Tax Burden by State – A comparison done by WalletHub that compared the 50 states on 3 types of taxes - property taxes, individual income taxes, and sales and excise taxes - as a share of total personal income in the state.

See a Restored Ancient Roman Helmet—and Two Shiny New Replicas – 2,000-year-old helmet made of silver-gilded iron.

Solar Savings in the US – Looking at the numbers….

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

Texas Solar Power Growth Changing the Shape of Daily Electricity Supply in ERCOT – Looking at the changes between 2022 and 2023…easy to see graphically.

Functional capacity in old age is like an ecosystem that may collapse when disrupted - In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning.

Ming Dynasty Tomb Found in China's Xinfu District – Part of excavations before nearby highway construction begins.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans - The rate with which we perceive the world is known as our "temporal resolution." Though our visual temporal resolution is quite stable from day to day in general, a post-hoc analysis did suggest that there may be slightly more variation over time within females than within males.

Study Reveals Vast Networks of ‘Ghost Roads’ in Asian Rainforests - An extensive analysis of satellite imagery has uncovered thousands of miles of unmapped roads slicing through Asia’s tropical rainforests - “ghost roads” may be laid down by miners, loggers, poachers, drug traffickers, and land grabbers, often illegally.

Volunteering Again

/

My first volunteering since moving to Missouri happened last weekend – helping set up a Friends of the Library in Christian County, Missouri book sale near where I live. I was part of the first wave of the set up so the first task was setting up the long folding tables around the edges and down the middle of the large space. There was one that seemed a little rickety and we quickly realized that it was not stable enough to load with books; it went back in the storage closet with a label that it was broken.

The boxes of donated books had been stored in a shed at the library and JROTC from the local high school loaded them onto a trailer and brought them over to our building. Fortunately the boxes were labeled well enough that we could aggregate them on the tables where the contents would be displayed. None of the volunteers with older backs (me included) had to lift any book boxes!

There were a large number of donated puzzles and I started emptying boxes and making a display that spread over two long tables. It seems that there were more puzzles than last year; maybe people are donating puzzles they bought during COVID. My goal was to get at least a small picture of the puzzle and the number pieces showing for each one. Most of the puzzles ended up in towers or standing on end.

It was a great way to spend a Saturday morning and I hope Friends of the Library make $$ from the sale that formally begins today.

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

What do terracotta warriors tell us about life in ancient China? – Discovered 50 years ago…they are a snapshot of the soldiers of Qin – the feudal state that unified China, for the first time in 221BC under the country's first emperor Qin Shi Huang – from the soles of their shoes to their candy-colored clothes to the bronze weapons buried with them to their distinct facial features. 2,000 terracotta warriors have been excavated but more are uncovered every year.

This Map Shows Where Planting Trees Would Make Climate Change Worse - Trees draw down carbon dioxide from the atmosphere, helping to keep warming in check. But their dark, green leaves also absorb heat from sunlight. Snow and sand, by virtue of their light color, reflect more sunlight back into space. As such, trees planted in snowy areas or in the desert will absorb more sunlight than their surroundings, which may negate the climate benefits of soaking up carbon dioxide.

These 3,000-Year-Old Treasures Were Forged from Meteoritic Iron - In the 1960s, researchers discovered a trove of Bronze Age treasure in Villena, Spain. New research has revealed that some of them made between 1400 and 1200 B.C.E. were forged from iron from a meteor that struck Earth a million years ago. Who manufactured them and where this material was obtained are still questions that remain to be answered.

Vernal Pools Make Your Garden Sing - It’s not just frogs that are making homes in these little pools of water. Less vocal species like salamanders, dragonflies, fairy shrimp, and even dozens of native plants are there too. Even more species than that can be found simply visiting the pool for a drink or snack, including great blue herons, wood ducks, and box turtles.

Return of Trees to Eastern U.S. Kept Region Cool as Planet Warmed - Over the 20th century, the U.S. warmed by 1.2 degrees F (0.7 degrees C), but across much the East, temperatures dropped by 0.5 degrees F (0.3 degrees C). A new study posits that the restoration of lost forest countered warming, keeping the region cool. Still, the return of trees can only partially account for the drop in temperature. Other possible explanations include the growth of irrigation, a source of water vapor, and the uptick in particulate pollution, which reflects sunlight, thereby cooling the air.

Sweetened drinks linked to atrial fibrillation risk - 20% higher risk of irregular heart rhythm, known as atrial fibrillation, among people who said they drank two liters or more per week (about 67 ounces) of artificially sweetened drinks. The risk was 10% higher among people who said they drank similar amounts of sugar-sweetened beverages.

Measles outbreaks and what parents need to know - Measles can lead to complications such as ear infections, diarrhea, pneumonia, and encephalitis (brain swelling). One to three of every 1,000 children infected with measles dies. More than 97 percent of the people who have had their two shots of the vaccine never get measles.

A new world of 2D material is opening up - 2D materials have shown great potential for an enormous number of applications. You can imagine capturing carbon dioxide or purifying water, for example. Now it's about scaling up the synthesis and doing it in a sustainable way.

In Cleveland, mushrooms digest entire houses: How fungi can be used to clean up pollution - Fungi can eat the noxious waste from abandoned homes. Heavy metals and other toxins are extracted and captured in the mushrooms that grow, while the substrate leftovers, including the mycelium, are compacted and heated to create clean bricks for new construction. The resulting "mycoblocks" have a consistency akin to hardwood and, depending on the specifics of the manufacturing process, have been shown to be significantly stronger than concrete.

Arctic nightlife: Seabird colony bursts with sound at night - Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.

Zentangle® – March 2024

/

The tile materials for the 31 tiles I selected from my March creations were more varied than usual. The thin cardboard rectangular tiles were the first I made. The unbleached color varies slightly – always warm. I like that this is reused cardboard mostly made from recycled paper/cardboard.

There were two tiles from index cards from my dad’s old office,

Four square tiles that were paperboard coasters,

Five square tiles that were colorful cardstock,

And nine tiles that were round paperboard coasters that were all started with the same string.

It was a good month for savoring tile creation…experiencing the Zen minutes they provided.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

  • The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

  • At night, the cranes move to the Platte River for safe roosting in the shallow water.

  • Sandhill cranes are the most numerous of the world’s crane species.

  • In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

  • Increase tree percentage in parks and green spaces

  • Provide shade on sites

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

Possible Neolithic Body Piercings Unearthed in Anatolia – Over 11,000 years old…found near ears and chins of human remains.

Under Threat in Their Native California, Giant Sequoias Are Thriving in Britain - First introduced to country estates in the 19th century, half a million sequoias now grow in Britain, compared to just 80,000 along the western flank of the Sierra Nevada in California, where they are increasingly imperiled by warming. Up to a fifth of all large giant sequoias in California died in wildfires in 2020 and 2021. The trees in Britain are still relatively young — sequoias can live for more than 3,000 years — and squat. In Britain’s cool, mild climate, sequoias are growing nearly as fast as in California.

Whales That Go Through Menopause Live Longer and May Help Care for Grandchildren - Female tooth whales that go through menopause (narwhals, killer whales, false killer whales, short-finned pilot whales and beluga whales) have longer lifespans than those that don’t, surviving decades past their reproductive prime!

A healthier diet is linked with a slower pace of aging, reduced dementia risk - We have some strong evidence that a healthy diet can protect against dementia…but the mechanism of this protection is not well understood. This study suggests that slower pace of aging mediates part of the relationship of healthy diet with reduced dementia risk, and therefore, monitoring pace of aging may inform dementia prevention. Additional observational studies need to be conducted to investigate direct associations of nutrients with brain aging.

The next pandemic? It’s already here for Earth’s wildlife – The pathogenic strain of avian influenza has killed millions of birds and unknown numbers of mammals. Between January 1, 2003 and December 21, 2023, 882 cases of human infection were reported from 23 countries, of which 461 (52%) were fatal. To prevent the worst outcomes for this virus, we must revisit its primary source: the incubator of intensive poultry farms.

Ultra-fast fashion is a disturbing trend undermining efforts to make the whole industry more sustainable - Ultra-fast fashion is marked by even faster production cycles, blink-and-you’ll-miss-it trends, and poor labor practices. Without change, the industry will account for 26% of the world’s carbon budget for limiting global warming to 2°C by 2050. Established brands such as Gap introduce 12,000 new items a year and H&M 25,000. But Shein leaves them in the dust, listing 1.3 million items in the same amount of time.

Our yard/yard work – March 2024

/

There is a lot going on in our yard this month. The bulbs I planted last year have thrived. The crocus bloomed first followed by the hyacinths and daffodils. The hyacinths don’t seem to bloom as well here as they did years ago in Maryland.

The forsythia bush in the corner of our yard is blooming profusely. I cut some to bring inside…and took some macro pictures of the flowers there. After the bush finishes blooming, I will trim it back significantly. I planted pawpaw seeds under it and I am hoping they come up…start my grove of pawpaw trees with the forsythia’s protection from the hottest parts of the summer days.

The fragrant sumac is blooming. I bought the young plant last spring after the bloom time so this is my first season to observe the small flowers.

The lambs’ ear is returning. The clumps that get more sun did not die back like the largest clump on the north side of the house. There are two in a sunny place that might merge over the summer.

The small hens and chicks are pretty with additional color forming on the tips of their leaves over the winter. There are still two chicks. I’ll be moving more rocks away from them so it will be easier for them to spread.

The vinca under one of our cedars is blooming. It seems to be well contained. I don’t want more of it!

I’ve planted more pollinator/butterfly garden seeds in two places: enlarging the existing wildflower garden and a sunny area under a pine tree where I cleared away most of the pine needles (it is sunnier there because I cut some low branches).

I’m not sure if the bulbs I planted from my parents’ garden are going to survive. They had to be planted in the winter…not the optimal time. Hopefully they will become established over this summer although I doubt they will bloom.

The mound where a pine tree used to be (it fell and had to be removed) is going to fill out nicely with irises and I planted a tiny oak there (I cut it from my flower bed last fall and put it in a vase to enjoy the fall color….it grew a root and put out green leaves! It will take years before it gets big enough to impact the bed but could eventually dominate the back yard!). The beautyberry that is there has not leafed out yet.

The hostas are beginning to emerge…in dense clumps. I decided to divide two clumps…since I have a shady place that I’d like to convert from grass.

I planted divided clumps (roots plus a furled leave or two) at the pine needle and flower bed boundaries with grass. I covered the grass with extra pine needles (from under the tree where I planted pollinator/butterfly garden seeds) and clippings from some bushes). I was thrilled when the hosta leaves unfurled within a day or two after they were planted!

There is still a lot to do in the yard. I get a little done every day I am at home and it’s dry…over 60 degrees.

Heat Pumps Are Still a Good Investment Even If Your Grid Is Powered By Coal - If every American home with gas, oil, or inefficient electric resistance heating swap those things out for heat pumps, the emissions of the entire U.S. economy would shrink by 5% to 9%. That’s how powerful a decarbonizing tool heat pumps are.

Asian Elephants Bury Their Dead - In India, five dead elephant calves were found buried on their backs in irrigation ditches, with evidence that multiple herd members had participated in the burials. Are there more examples? It doesn’t seem likely that elephants would be able to move an adult elephant like they did the calves. Do they do something else with the carcass rather than burial?

COVID-19 virus can stay in the body more than a year after infection – So – if it persists in blood, should these people not be donating blood? Does this mean that people could get COVID from a blood transfusion?

Archeoastronomy uses the rare times and places of previous total solar eclipses to help us measure history – What we learn from historical eclipses….a timely history lesson with the 4/8 total eclipse that will be visible from much of the US coming soon.

An Eruption for Galápagos Iguanas – The La Cumbre volcano is erupting in the Galapagos. Some satellite views from NASA including a description of the instrumentation available to monitor this eruption.

An obsessed insect hunter: The creepy-crawly origins of daylight savings – We did it again last weekend…changed to daylight savings time. I wish we could stop (don’t care whether we stay permanently on standard or daylight savings…just that we don’t change) but we don’t seem to be able to stop. This post is about George Hudson…and his desire for more daylight after work to study insects! I’ll browse some of his books on Internet Archive.

Solar Accounted for More Than Half of New Power Installed in U.S. Last Year - Solar accounted for most of the capacity the nation added to its electric grids last year. That feat marks the first time since World War II, when hydropower was booming, that a renewable power source has comprised more than half of the nation’s energy additions. Texas and California led a solar surge driven mostly by utility-scale installations, which jumped 77 percent year-over-year to 22.5 gigawatts. The residential and commercial sectors also reached new milestones. The biggest open question is how quickly projects can connect to the grid.

An inside look at Beech tree disease – A fast spreading disease….killing another tree species. It hasn’t been that long ago that Emerald Ash Borer wiped out the ash trees. We were just noticing sickly beeches in Maryland before we moved…realizing that the forests would be profoundly changed without beech trees.

Apples, Walnuts… and Toast? A New Study Reveals the Flavors of Ancient Roman Wine - Georgian vintners still employ a rustic approach. Grapes are crushed by hand or foot, placed in egg-shaped vessels known as qvevri, and buried for up to six months. It’s a UNESCO-recognized tradition dating back 8,000 years and researchers believe can help reveal the sight and scent of ancient Roman wine.

Mexico is suing US gun-makers for arming its gangs − and a US court could award billions in damages - In January, a federal appeals court in Boston decided that the industry’s immunity shield, which so far has protected gun-makers from civil liability, does not apply to Mexico’s lawsuit. Mexico’s lawsuit alleges that U.S. gun-makers aided and abetted illegal weapons sales to gun traffickers in violation of federal law. According to the lawsuit, feeding demand for illegal weapons is central to the industry’s business model.

Climate change reversing gains in air quality across the U.S.: study - The study finds that climate change is increasing the prevalence of two of the air pollutants most harmful to human health: particulate matter, commonly referred to as PM2.5, and tropospheric ozone. Whereas pollutants from cars and factories could be targeted by regulations over the past few decades, climate-related deterioration in air quality is a much tougher problem to solve.

Avar Grave Offers Clues to 7th-Century Heavy Cavalry - Thought to be a complete set of lamellar armor, which was made from hundreds of small iron plates, was spread out over the warrior.

What Does a Solar Eclipse on Mars Look Like? New, Breathtaking Images, Caught by NASA’s Perseverance Rover, Give Us an Idea – Images of Phobos passing across the sun’s surface…back on February 8.

Benefits of heat pumps - Nationally, heat pumps would cut residential sector greenhouse gas emissions by 36%-64%!

How millennials could give the suburbs a much-needed makeover – The trend is to move to the suburbs and not feel like you need to go to the city to have a great dinner or to see a show or live music or the arts.

The far-reaching impacts of wildfire smoke – and how to protect yourself - One study found that a quarter of the US's PM2.5 pollution was caused by wildfire smoke. In western regions, as much as half was caused by smoke. If there is a wildfire nearby, the Centers for Disease Control and Prevention advise taking steps to limit your exposure where possible:

Choose a room to close off from outside air

Wear a tightly fitting respirator, if it is safe for you to do so

Keep track of fires nearby using services such as AirNow's fire and smoke map

Pay attention to health symptoms and seek medical care if needed

Ancient Lipstick Dating Back More Than Three Millennia Is Found in Iran – Analysis of the loose, dark purple fine powder revealed minerals (hematite, quartz, braunite, anglesite, and rare tiny crystals of galena) and vegetal fibers.

In Scotland, Renewable Power Has Outstripped Demand – A milestone for Scotland. The volume of electricity produced by renewables in Scotland was equal to 113 percent of demand in 2022. Fossil fuels still supply some electricity, helping to smooth over gaps in renewable power. Across the U.K., fossil fuel power is at its lowest level in nearly seven decades. Impressive.

Surprisingly vibrant color of 12-million-year-old snail shells – Polyenes (includes carotenoids) preserved almost unchanged…and found in fossils.

Asbestos: The strange past of the 'magic mineral' – Asbestos was woven into textiles fit for kings and used for party tricks. One 18th-Century philosopher even slept in a night-cap made from it. It was also used to make the funerary shrouds for monarchs; because it didn't burn, it helped to keep their ashes separated from the rest of the pyre. An account from Ancient Greece describes a golden lamp made for the goddess Athena, which could reportedly burn for a whole year without going out and had a wick made from "Carpathian flax" – thought to be another name for asbestos. In 1899, an English doctor recorded the first confirmed case of a death linked directly to the material – a 33-year-old textile worker who had developed fibrosis of the lungs. In the UK, all asbestos was banned in 1999, but much of the asbestos added before this date remains in place – as buildings degrade, it is posing a significant health risk.

Rise of Peru’s Divine Lords – Hilltop sites in the Andes…early examples of divine lordship - a form of leadership that would endure in Peru for more than 1,000 years.

Amid Record Drop in Fossil Power, Europe Sees Wind Overtake Natural Gas - The E.U. power sector is undergoing a monumental shift - fossil fuels are playing a smaller role than ever as a system with wind and solar as its backbone comes into view. Coal generation fell by 26 percent, while gas generation fell by 15 percent.

Student Design Competition: Integrating Solar and Agriculture - Some 2.8 gigawatts of agrivoltaics exist across the U.S. Many combine solar energy with pollinator habitat and sheep grazing. The National Renewable Energy Laboratory (NREL) is looking for new design proposals from graduate and undergraduate landscape architecture students to push the agrivoltaics envelope!

The Moon Is Shrinking, Causing Moonquakes at a Potential NASA Landing Site - Researchers examined data on moonquakes detected by lunar seismometers, which have been on the moon since Apollo program astronauts left them there more than 50 years ago. They also used mapping data from NASA’s Lunar Reconnaissance Orbiter to identify the telltale creases on the moon. Through modeling, they linked these faults to seismic activity.

Texas Reservoirs Reach Dangerous Lows - In Corpus Christi, on the south Texas coast, authorities last month stopped releasing water aimed at maintaining minimum viable ecology in the coastal wetlands, even as oil refineries and chemical plants remain exempt from water use restrictions during drought. On the lower Texas coast, the Rio Grande has not been flowing consistently, and Colorado River water releases have been minimal as that river faces shortages farther upstream.

Extreme Birding: Gull Watching at the Landfill - You can find gulls around North America (and many parts of the world), including in interior states. At least 28 gulls can be seen in North America, with additional vagrant species showing up from time to time. Individual species look different depending on age and other factors. A gull goes through three feather molts in its first year.

Poisonous Seed Stash Discovered in the Netherlands – Black henbane contained in a hollow goat (or sheep) thigh bone sealed with a plug of black birch bark…from AD 70-200.

Ocean Sponge Skeletons Suggest a More Significant History of Global Warming Than Originally Thought - An analysis of six sea sponges—centuries-old creatures with an internal chemistry that holds secrets about climate history—points to global temperatures already having increased by 1.7 degrees Celsius due to human activity --- that’s more than scientists currently agree upon….so there is a flurry of activity to corroborate the finding.

Ramping up Elder Care – February 2024

/

My parents have rediscovered the joy of going out to a restaurant for a meal. The weekday late lunchtime seems to work best (i.e. not crowded). It is quite a production: two elderly people with walkers…and two (or three) others with them. One of my sisters bought a small refrigerator for their room and they relish being able to put their leftovers there (and seem to prefer eating them for their next meal!). This is probably something I will try to do with them every time I visit. There are a lot of restaurants near the assisted living group home to experience.

Sometimes major bends in our life path are only recognized in retrospect; the events of January and February 2024 are a bend everyone in my family anticipated and acknowledges in real time. My sisters and I are acclimating to others providing the day to day care of our parents with their move to an assisted living home and the family has lost a long term hub for family events with the selling of their house.

  • My parents moved to an assisted living group home at the end of 2023. They’ve settled into their new environment. My mother is improving; maybe it is simply a trend that started back in December, but it could also be the increased social interactions and her confidence that someone is always available to help. It is still challenging for my sisters and I to back away and not jump to assist them when we visit. The staff is helpful and patient with everyone! My dad is about the same although he was very disoriented at first; he is eating well.

  • My sisters and I began to clean out my parents’ house soon after we moved them. They had lived in the house for over 30 years. There was a lot to go through. I made two short (less than a week) trips to Carrollton to help. During January we cleared most of the house by

    • Distributing furniture to family members or selling it or marking it for donation. I took two small tables, and my daughter took a larger octagon table for her office.

    • Donating clothes. There was very little that someone else in the family could wear. The closets in their assisted living rooms are filled to the brim with clothes that they wear.

    • Following the ‘bequeath’ list for decorative and kitchen items. I got 2 items from their 50th anniversary (one passed down from my maternal grandparents’ 50th), 1 from my parents’ 25th  anniversary, items that I remember from my childhood (a knife, fork and spoon of the silver plate my mother bought before she married; a orange cut glass bowl that I bought as a present to my Mother because it was her favorite color), 2 paintings my mother made (one of a dogwood blossom…and the pressed flower that I sent to her in 1984 from my Virginia house that she used as her model), the remnants of my maternal grandmother’s China….too many things to name although I am realizing that I should make a list for myself.

  • The house went on the market on February 1st and we accepted a full-price offer on the 2nd. Closing was requested for 2/28. February became a sprint to clear out the two sheds on the property and donate the furniture that no one in the family wanted. I made a very focused trip to help.

    • Salvation Army came with a truck to get furniture and boxes of books. It was tricky since the city had the street in front of the house torn up (infrastructure update project). The truck managed the pickup from the alley.

    • Tools were mostly distributed to the sister that wanted them. Some were tools from my paternal grandfather.  My daughter got a telescoping tree trimmer (she has the bigger trees…but I can borrow it when I need it).

    • The trash and recycle bins were full for every pickup and some items were put at the curb in front of a neighbor’s house for bulk pickup.

    • Some odds and ends were taken to be repurposed. I got some white vertical blinds (not attached to anything…just loose pieces of blind) which I plan to cover with Zentangle patterns and hang (not sure where yet). There were three small pieces of Masonite that I got for another Zentangle project. Some pieces of wood were taken by my sisters for art projects and specific repairs at their house.

    • One sister is having the king headboard (purchased in 1963…beautiful wood) made into a display case. She also took the antique meat grinder that we found in one of the sheds.

    • Another sister is taking most of the yard equipment to distribute to her family’s houses so that it will be easier for her to do yard maintenance.

Are we through the bend….or is more to come before we settle into a new normal? As I write this my dad has tested positive for COVID-19. The symptoms were mild and initially attributed to some new eye drops. He was tested after one of my sisters that visits frequently tested positive. He is getting Paxlovid. This is the first experience with COVID for him and my mother; they are both vaccinated. Hopefully this will be a minor blip and we’ll achieve a new normal in March.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The lost art of the death mask – In the late Middle Ages (after 50% of the population was wiped out in 4 years by plague), death masks were created by molding wax or plaster over the face, and were a useful way of copying the features of deceased relatives, so that sculptors could use them as a reference for the lifelike portraits displayed at funerals. Then in the 18th Century, something unexpected happened: people began to value death masks for their own sake. Many death masks were turned into spooky heirlooms, while some became souvenirs that command six-figure sums to this day.

Rapa Nui’s Rongorongo Tablets in Rome Radiocarbon Dated - In the nineteenth century, Roman Catholic missionaries took four wooden tablets bearing rongorongo glyphs from Easter Island. They have recently been radiocarbon dated; three of the tablets were made from trees cut down in the eighteenth or nineteenth centuries; the fourth tablet came from a tree felled sometime between 1493 and 1509, some 200 years before the arrival of Europeans in the 1720s.

Tribe Making Play to End Oil Development at Big Cypress National Preserve - The National Park Service took charge of the land 50 years ago, which is a haven for some of Florida’s most endangered wildlife species, such as the Florida panther — but not the mineral rights under the land. Those are owned by the Collier Resources Company, which has from time to time dispatched oil companies to the preserve to look for black gold.

Bird Alert: The Search for Local Rarities – The joy of birding close to home!

Archaeologists discover oldest known bead in the Americas - At the La Prele Mammoth site in Wyoming. Made of bone from a hare. Almost 13,000 years old.

Stunning Macro Photos Pay Homage to the Frozen Beauty of Winter – A good reminder to check ice as a subject for winter photography!

Ancient pollen trapped in Greenland ice uncovers changes in Canadian forests over 800 years - The onset of the Little Ice Age around 1400 and the arrival of European settlers and subsequent intensive logging practices around 1650. The pollen in ice can be dated almost to the year it was deposited!

Back Pain Explained - Many people with degenerated discs feel no pain at all….but others have severe pain. It appears that when aging or under degenerative stress, a subset of cells in the center of the disc can release a cry for help, a particular signal that causes outside neurons to extend their axons within, allowing the brain to feel the pain inside. This work could inform future treatments for discogenic lower back pain!

PACE Makes it to Space – NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) was launched February 8…preparing to move into operational phase soon.

How our drinking water could come from thin air - The solar-powered hydropanels work by using sunlight to power fans that pull air into the device, which contains a desiccant material which absorbs and traps moisture. The water molecules accumulate and are emitted as water vapor as the solar energy raises the temperature of the panel to create a high-humidity gas. This then condenses into a liquid before minerals are added to make it drinkable. There are several startups with other approaches to produce water from air too. And they all work even with dry air.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Sleep tight: A curious history of beds through the centuries – From 4,500 year old ‘beds’ at Skara Brae (Scottish island of Orkney…rectangular enclosures, around the length of a human…made from slabs of cold, hard stone…with tall headboards and raised sides) to Durrington Walls near Stonehenge (spectral outlines of long-vanished wooden bed boxes, where the builders of that monument may have once slept) to a clay figurine of a woman slumbering peacefully on her side, one hand under her head, on a simple raised platform to the gilded wooden bed in King Tut’s tomb (including a rigid, raised headrest rather than a soft pillow) to mats of dried leaves or animal skins to box beds to the ‘tick mattress’…hints of beds of the past.

Peru’s High-Altitude Hunter-Gatherers Ate Mostly Plants – Wild potatoes and the root vegetables made up 80% of their diet.

Rethinking Monarchs: Does the Beloved Butterfly Need Our Help? - The Xerces Society has published a joint statement signed by 10 top monarch biologists warning against the captive rearing and releasing of monarchs by backyard and commercial breeders. Such activities, they wrote, “promote crowding and disease spread.” The monarch is not in peril since the winter population in Mexico has shown no continued decline for the past 10 years. --- But there are some that still argue for continued ‘help.’

Deceptively Beautiful Invasive Plants – Avoid Lessor Celadine, Mimosa Tree, English Ivy…..Today, we have the opportunity to make gardening choices that benefit both the aesthetics of our gardens and local wildlife by removing invasive species and replacing them with beautiful and wildlife-friendly native alternatives. 

See the World Through the Eyes of Animals with These Stunning New Videos - To “see through” animal eyes, the team uses two cameras—one sensitive to ultraviolet light and one sensitive to visible light. Together, they capture light in four distinct wavelengths: blue, green, red and ultraviolet.

New genetic variants found in large Chinese mother–baby study - Mothers with higher blood pressure give birth to lighter and shorter babies than do mothers with lower blood pressure. This was just one of a multitude of links between maternal health and fetal development observed in a large genetic analysis of Chinese parents and their babies, which included some unexpected results. The researchers sequenced genetic data from blood samples taken from the parents and umbilical-cord blood of the infants and collected physical information about the mothers and their babies, including height and weight. The researchers identified discrepancies in the effect of some genetic variants on the same trait between mothers and their babies. For example, some variants were associated with altered cholesterol levels in infants but not in their mothers, and vice versa.

Preserving History at Bandelier National Monument – Two videos that show recreations of what the structures looked like in use based on archeological findings.

The 4-Second Nap: Unusual Sleep Habits of Animals - The killer whale, which can go a month or more without sleeping. Or the chinstrap penguin, which researchers recently discovered sleeps in four-second microbursts. Compare that to the koala, which conks out for most of the day.  When dolphins are sleeping with one hemisphere, one eye closes and one remains open. They sometimes rest motionless near the surface of the water or swim slowly, still able to breathe when needed. African elephants sleep for the least amount of time recorded of any land mammal.  The domestic horse sleeps just under three hours on average each day, and the domestic pony sleeps about three hours and 20 minutes. 

How a walk in nature restores attention - The study, conducted in 2022 between April and October, analyzed EEG data recorded on each of 92 participants immediately before and after they undertook a 40-minute walk. Half walked through Red Butte, the arboretum in the foothills just east of the University of Utah, and half through the nearby asphalt-laden medical campus. The participants that had walked in nature showed an improvement in their executive attention, whereas the urban walkers did not.

Climate change is causing a pothole plague. Are robots and self-healing pavement the solution? - In the United States, about 44 million drivers reported damage to their vehicles from potholes in 2022, which was a massive 57% increase over 2021, according to AAA. New developments offer hope for addressing potholes more effectively amid climate change, and are attracting investors….but innovations take time to be implemented.

5 Ways Power Sectors Worldwide Can Drive Down Emissions - The coal-to-clean transition is complex — how effective it ends up being hinges on ensuring ambitious climate action integrates priorities around energy security, affordability, reliability, and meeting growth in electricity demand.

The 'dark earth' revealing the Amazon's secrets - Amazonian dark earth(ADE), sometimes known as "black gold" or terra preta, is a layer of charcoal-black soil, which can be up to 3.8m (12.5ft) thick, and is found in patches across the Amazon basin. It is intensely fertile – rich in decaying organic matter and nutrients essential for growing crops, such as nitrogen, potassium and phosphorus. But unlike the thin, sandy soils typical of the rainforest, this layer was not deposited naturally – it was the work of ancient humans. Now businesses are attempting to capitalize on this ancient method, in a quest to help farmers to improve their soil and combat climate change at the same time.

Rusting Rivers - Researchers suspect that thawing permafrost is the cause of dozens of Alaskan streams turning orange. Along with the strange appearance of the water, they have found it tends to be higher in iron, lower in dissolved oxygen, and more acidic than nearby rivers that run clear. The dramatic shift in water quality may be felt most acutely in the villages that rely upon rivers originating in permafrost regions for fish and drinking water.

World’s Largest Green Hydrogen Plant Will Take a Poke at Russian Gas - Mitsubishi is putting up $690 million to help build the world’s biggest green hydrogen plant, to be located in the Netherlands. It will help patch up some holes in the energy independence plan of Europe, where Russian gas has been clinging to a foothold despite sanctions.

Greece Reopens the Palace Where Alexander the Great Was Crowned - The 2,300-year-old Palace of Aigai—the largest building in classical Greece—had been under renovation for 16 years. At 160,000 square feet, the Palace of Aigai was classical Greece’s largest structure. Built primarily by Alexander’s father, Phillip II, in the fourth century B.C.E., it was the home of the Argead dynasty, ancient Macedonia’s ruling family. It was destroyed by the Romans in 148 B.C.E. and endured a subsequent series of lootings.

Predictions For Heat Pump Adoption Trends In 2024 - With $8,000 rebates for space heating heat pumps, and $1750 for water heating heat pumps, the IRA is helping accelerate adoption of this technology.

Miners Discover Seven-Foot Mammoth Tusk in North Dakota - Coal miners in North Dakota have uncovered a seven-foot-long, 50-pound mammoth tusk that’s been buried for thousands of years. Paleontologists have found more than 20 additional mammoth bones so far, including parts of hips, ribs, a tooth. and a shoulder blade.

The new drugs that may bring an end to constant itching - One in five of us will experience chronic itch lasting weeks or months. Fortunately, there might be treatments that address the problem.

Global groundwater depletion is accelerating but is not inevitable - This study shows that humans can turn things around with deliberate, concentrated efforts. Fine resolution, global studies will enable scientists and officials to understand the dynamics of this hidden resource.

Syphilis microbe’s family has plagued humans for millennia - Remains of people who lived on the eastern coast of South America nearly 2,000 years ago have yielded the oldest known evidence for the family of microorganisms that cause syphilis.

Can autoimmune diseases be cured? - After decades of frustration and failed attempts, scientists might finally be on the cusp of developing therapies to restore immune ‘tolerance’ in conditions such as diabetes, lupus and multiple sclerosis.

Good and bad news for people with low back pain - The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months. The bad news is that once you have had back pain for more than a few months, the chance of recovery is much lower. This reminds us that although nearly everyone experiences back pain, some people do better than others, but we don't completely understand why.

Why diphtheria is making a comeback - While this present surge of diphtheria cases is indeed unprecedented for West Africa, it is really a symptom of larger issues in global health, including insufficient infectious disease surveillance, poor vaccination rates and scarcity of public health resources.

The Prairie Ecologists Photos of the Week – January 22 2024 – Photographs from out in the cold.

The chemistry of meat alternatives – It’s complicated…..in the end are meat alternative ultra-processed food?

The strange reasons medieval people slept in cupboards – I can see how they might have been warmer….but also rather claustrophobic. And wouldn’t they be hard to keep clean?

In the time of the copper kings - Some 3,500 years ago, prosperous merchants on Cyprus controlled the world’s most valuable commodity. Beginning in the third millennium B.C., and especially during the second millennium B.C., copper was king and could make those who possessed it extremely wealthy and powerful. There was enough copper and tin on board the Uluburun ship (wrecked off the coast of Turkey) to produce 11 tons of bronze, which experts estimate could have been turned into 33,000 swords. Researchers have analyzed the Uluburun wreck’s copper and found that it all came from Cyprus. There is evidence of the surprisingly diverse nature of the community thriving there and that those Cypriots who controlled the production and distribution of copper, such as the shipment found off Uluburun, could become exceptionally rich.

Cicadas Are Coming: Rare ‘Dual Emergence’ Could Bring One Trillion of the Bugs This Year – We don’t live in the overlap area…but where we live in Missouri will see Brood XIX this summer….a great opportunity for cicada photography!

Incredible Winners of the Close-Up Photographer of the Year Contest – So many beautiful images. My favorite is ‘Spirit of Yucatan’ (drifting stems of lily pads in a Mexican freshwater cenote…the sky above).

What were the death tolls from pandemics in history? – The two most recent ones are COVID-19 and HIV/AIDS. Death from the 1918-1920 flu pandemic was larger than both together….and the population of the world was less then too.

Moments of hope and resilience from the climate frontlines – Drought then intense rains leading to rolling blackouts, damage to infrastructure, agriculture failures, mosquito spread diseases. Heat stress leading to deaths of people and wildlife, wildfires. Protecting and rehabilitating damaged habitats. A new normal….not anyone ready. Heat officers to help residents cope. Coastal erosion (caused by coastal development, rising sea levels and storm surges). Taking two years rather than one to dry firewood in Lapland. Solar panels positive impact on health care in India (and anywhere where electric power is unreliable). Crop irrigation required where it previously was not. Learning from our past, simpler lifestyles.

European Imports of Russian Pipeline Gas Dropped by Half Last Year - Europe has implemented measures to conserve energy and has ramped up wind and solar power. Last year, Germany, the largest economy in Europe, drew more than half of its power from renewables for the first time.

Fevered Planet: How a shifting climate is catalyzing infectious disease – The geography of disease is also changing as novel pathogens affecting plants, animals and humans increase their range. New beetles are heading north and devastating Siberian forests, Alaskan mammals are struggling as new ticks arrive and human habitations in northern Norway are infested by new insects.

‘Green Roads’ Are Plowing Ahead, Buffering Drought and Floods - Designing roads to capture water through strategic channels, culverts, and ponds and divert it for agricultural use. Nearly 20 countries have either implemented Green Roads for Water or plan to begin soon, and thousands of kilometers of roads, worldwide, have already received Green Roads interventions.

Fresh water from thin air - Atmospheric water harvesting (AWH). The need for more affordable options has spurred interest in ‘passive’ AWH systems that use moisture-hungry sorbent compounds to collect water. The small amounts of power that such systems require could, ideally, be supplied by the Sun. Typically, these sorbents are exposed to the air overnight, when temperatures are cooler and moisture is more abundant. They collect the airborne moisture as liquid in a process known as adsorption. When day breaks, the sorbents are transferred to a device that uses solar energy to drive the release of water. This water is then condensed and collected. And there are abundant opportunities beyond simply producing drinking water. For example, a harvesting system that piggybacks on existing photovoltaic solar panels, using the waste heat and energy from these panels to power water production9; the resulting water helps to cool the panels and therefore improves their efficiency

Archaeologists Discover Brutal ‘Bakery-Prison’ at Pompeii - The cramped space provided minimal light, as windows to the outside were small, high and barred.

Houses built to survive floods - The Manobo indigenous people live and thrive on a vast wetland in the Philippines – despite dealing with dozens of storms and floods per year. Their homes are built on floating platforms as a traditional way of coping with regular floods and storms, and the method proved resilient even in the face of aexceptionally powerful typhoon.

Hunter-Gatherer Childcare Studied - The infants of ancient hunter-gatherers were likely to have received attentive care and physical contact for approximately nine hours a day from about 15 different caregivers. Working with modern hunter-gatherers (the Mbendjele BaYaka who now live in what is now the Republic of Congo), researchers found that the children often have more than 10 caregivers, and sometimes more than 20. These people, including older children and adolescents, support the mother in responding to more than half of her baby’s cries, resulting in improved maternal rest and well-being and thus enhanced maternal care.

Why Does Everything Taste Like Chicken? - Comprised of white muscle fibers, chicken breast and wings rely more on glycogen than myoglobin since they are specialized for more sporadic and brief energy demands. Likewise, unique meats such as frogs and alligators are also considered white meat. They boast a leaner meat profile, a palatable flavor, and a chicken-like texture.

Socio-cultural practices may have affected sex differences in stature in Early Neolithic Europe - Biological effects of sex-specific inequities can be linked to cultural influences at least as early as 7,000 yr ago, and culture, more than environment or genetics, drove height disparities in Early Neolithic Europe.

People Can Be Prescribed “Photography” as a Mental Health Treatment in the UK – “Once a GP or healthcare professional refers a patient to the “Photography on Prescription” program, they will be granted access to photography equipment and masterclasses by Wex, with the intention of giving them the tools to improve their mental health.” What a great idea! It appears that the classes from Wex are available on YouTube!

Gelatine: The ingredient with the wonder wobble - Gelatine, made from the connective tissues of animal parts, is an unlikely staple ingredient. A thousand years ago in Iraq, when the cookbook containing the recipe was written, party guests might have welcomed a slice of the jiggling substance, much the way the attendees of a Tupperware party in Omaha in 1963 would have tucked into a brilliant green molded Jell-O larded with canned mandarin orange slices. Gelatine is made by boiling the bones and connective tissue of animals, breaking down the protein known as collagen. The proteins released by the process will cling together at room temperature, but if they are mixed with hot water and then allowed to cool, the water is threaded through the network they form. Different concentrations of the proteins will yield different firmness of the final gel.

Massive Ancient Mosaic Floor Discovered in Turkey -  A large floor mosaic covering some 6,400 square feet has been uncovered in central Anatolia, in a Roman villa dated to the fourth century A.D.

These Are the Best Northern Lights Photos of 2023 – Color in the sky. My favorite is the one full of greens titled “Circle of Life.”

How ancient civilizations dealt with trauma - Just a year after the Norman conquest, a group of bishops got together to create an unusual list - a set of instructions for those who had participated in the bloodshed – setting out the repentant actions they should perform to atone for their deeds. To help veterans avoid trauma and give them tools to deal with it, medieval societies relied heavily on religion. There were prayers and blessings from priests before battles, and penances allowed veterans to absolve themselves of any atrocities they had committed. Later, during the Crusades, people were told that entering into war was a holy act itself, and could do away with all your previous transgressions. the Ancient Romans invested heavily in getting the proper permission from the gods for their wars. In the ancient world, as today, war often spilled over into the world of the general public – leading to rape, torture, slavery, theft, murder and the mass displacement of people, with entire cities razed to the ground.

Sustaining Myself in the Caregiving Role

/

I left my home in Missouri on November 15th and have been learning to be the caregiver my parents need at this point in their lives until my sisters and I can transition them to a new living situation that will meet their needs into the future. Now that it has been more than a month, I realize that some of my strategies developed during my career to reduce my stress and maintain my overall mental health are still serving me well:

  • Writing about something stressful as a way of letting it go…moving from anxiety to acceptance for things that cannot be changed.

  • Creating a little work of art every day (Zentangle)…focusing totally on it for the short time it takes to create it…a break from everything else going on.

  • Continuing a daily blog post that not only documents my journey…but produces something separate from the caregiving part of the day

I have discovered that little things that remind me that my other life still exists and is waiting for me to return are important to me – a telephone call with my daughter or husband (they have both been very supportive)….a walk outdoors even if it is just for a few minutes…photography. At the same time, finding bits of time for these activities can be a challenge. There is a similarity to caring for a young child: nap times for them become ‘me time’!

As I write this post, I am realizing that I am not fully sustaining myself for an indefinite period of caregiving and neither is my sister that is sharing caregiving with me. We are not as sleep deprived as we were during the hospitalization but we are not storing up reserves either; when little things go awry we are instantly feeling the stress of the situation and consciously staying focused exclusively on what our parents need.  We already have started the process to change my parents’ living situation in January that will shift much of the care giving role to assisted living staff; our interactions with our parents will shift to frequent visits and shared activities. We are preparing ourselves and them for the transition.
