Gleanings of the Week Ending April 20, 2024

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.

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.

L'art Vietnamien (ebook)

L’art Vietnamien was written by Louis Bezacier, a French archaeologist and art historian. It was published in 1955.

L'art Vietnamien

As I browsed the book, I found myself wanting more illustrations; the ones that were there acted to stimulate my interest but not satisfy it. I also wondered how much of Vietnam’s art history was damaged or destroyed in the battles that followed. The author first began his work in Vietnam in 1935 and published for at least 20 years after that…but this book is the only one that is currently on Internet Archive.

Ducklings 2024!

Last year I saw ducklings on our neighborhood pond on April 14th. This year I photographed this year’s brood 3 days earlier than last year on the 11th (although a sighting was posted on the neighborhood Facebook page on the 9th). There are 14 ducklings this year; no losses so far. The Mom Mallard was wisely keeping them close to shore protecting them from the turtles (turtles can pull a duckling underwater, drown it, and then eat it). Click on the images below to enlarge…see if you count 14 ducklings. When they are close to shore, one or two seem to always want to climb up on the mud and nibble the grass. The last picture has all 14 (I think). Their down make their bodies look out-of-focus, so count the heads!

Zoomed in, the ducklings show how fuzzy they still are.

Mom Mallard took them on a brief loop out into the pond before going back to the shore. The line of ducklings is somewhat easier to count.

I noticed some other things around the pond: robins,

Plastic swans (an attempt to deter geese from nesting near the pond),

And, of course, turtles. Most were red-eared sliders; there might be one that I photographed that was something else. I didn’t see the large snapping turtle. I’m not sure how large a turtle has to be to pull down a duckling. Fortunately, the Mom Mallard was keeping them at the other end of the large pond.

Before I headed home, I saw the ducklings again in the inflow channel of the large pond; there had been enough rain recently that there was still water in it and the ducklings were loving it! They were moving around finding bits of food and sitting down letting the water move around them. I wondered where the Mom Mallard had made her nest since they seemed to be heading up stream.

Then and Now: Groceries

In the 1960s, my mother did the grocery shopping for the family – usually going once a week.  I went with her occasionally but not often. She usually shopped while my sisters and I were in school. Her favorite grocery store was Safeway. I am now shopping at Walmart most of the time since it is the closest grocery store to me and once a week is still my goal. The hours my The Walmart is open from 6AM-11PM, 7 days a week; the hours grocery stores were open in the 1960s was a lot less than that and there were items they couldn’t sell on Sundays if they were open then (‘blue laws’ in Texas).

The carts were similar in design to the larger ones in most stores now although they were all metal (no plastic) and did not have seatbelts for young children. Most grocery stores now  have a few smaller carts along with the larger ones but I usually am buying enough that I get a large cart.

My mother always had a list that accumulated over the week; most of the time she made the additions to the list but as my sisters and I got old enough, we sometimes wrote in items. Now I use the OurGroceries app so that my husband and I can add items to the list from any of our devices and I use my phone when I am in the store rather than a piece of paper.

My mother only bought food at the grocery store…not toiletries or over-the-counter medications; those were purchased at a drug store which also included a pharmacy. I buy many non-groceries during my weekly shopping now; toiletries are frequently on the list, but I sometimes buy clothes or office supplies as well. It’s an advantage of shopping at Walmart rather than a grocery store. We still pick up our prescriptions at a CVS; the pharmacy at Walmart is not open at the time I usually shop (between 7 and 8:30 AM on Friday mornings).

At checkout, a cashier had to enter the price of each item on the register and the strip of paper that my mother was handed at the end only included the prices and the total. She paid with cash or wrote a check. Now I scan my purchases myself, use a credit card to pay for them, and get an itemized list that includes an abbreviated description of each item along with the total.

Mother’s purchases were put in brown paper bags by the cashier. Now the store provides single-use plastic bags; I’ve used my own bags for more than a decade (they are stronger, and I don’t have to take precautions to contain the single-use bags from littering and polluting the environment). I put my items into my bags after I scan them. All the refrigerator items go into an insulated bag and the remaining items are grouped into bags to make unloading easier once I get home (and to make sure bread, chips, and eggs are not damaged in transit).

There was a lot less plastic. Milk came only in cartons (waxed…not plastic coated) and juices and soft drinks came in glass. Canned foods were purchased frequently, and the cans were not lined with plastic. The produce section included mainly seasonal foods along with ones that could be easily stored/transported (like bananas). Broccoli was something we had periodically as a frozen vegetable, and it was packaged in a box rather than a plastic bag.  We enjoyed strawberries seasonally or frozen (in a box); now my husband likes the frozen ones (in a plastic bag) more than he likes fresh ones! Plastic is the dominate packaging now: jugs of milk, bottles of water/soft drinks/juice, bags of frozen veggies and fruit, robustly sealed meats, bags of snacks and fresh vegetables/fruits, jars of peanut butter. Sometimes there is an option to buy in class jars but most of the time there is no choice; the packaging is plastic.

The most common type of bread was white; my mother wanted ‘whole wheat’ and bought Roman Meal when she could find it. I buy Dave’s Sprouted organic bread….avoiding a lot of added chemicals that have been introduced over the years to keep bread from molding or otherwise ‘improving’ it in some way (‘improving’ is in quotes because many breads cross over into the ultra-processed realm with the additions that are quite common today).

Some of the brands are still around: Cambell’s, Nabisco, Kelloggs, Green Giant. I don’t buy them as often as my mother did…only Cambell’s Tomato Soup and Green Giant Niblets Corn for my husband.

There are a lot of products in the grocery store that were not available in the 1960s…most of them ultra-processed and they fill up whole aisles of the grocery store. It requires some willpower to steer clear of those (although it gets easier over time). On the healthier side, it is now easier to find international foods (salsas and tortillas, etc.) and things like boneless chicken breasts…a lot more options when it comes to pasta, sauces in glass jars, greens (kale and arugula were not in grocery stores in the 1960s), grains/seed (quinoa and chia are new…’chia pets’ were not introduced until the later 1970s), and no salt seasonings. There are now targeted foods for special diets; for example, milk that includes Lactaid for those that are lactose intolerant and protein shakes for diabetics or those dieting and concerned about getting adequate protein.

My mother was very conscious of nutritional guidelines; she had taken home economics courses in college. We had some form of protein at every meal along with fruits and vegetables and grains. Sugary items were only for special occasions. There were seasonal fresh foods, but she relied on canned goods more than we do now, particularly during the winter. Both sets of grandparents had big gardens and we enjoyed their bounty whenever we could – supplementing what was purchased at the grocery store; we knew how food was grown and a little of how it was preserved (canned) for later. Now we buy more fresh or frozen fruits and veggies rather than canned because they are readily available during the whole year. I also buy organic as much as I can….something that didn’t exist in the 1960s.

Groceries have changed significantly since the 1960s. Availability of healthy foods is probably better now – although it takes more attention/knowledge to avoid the ultra-processed foods that are often intermingled with the healthy food.

Previous Then and Now posts

Solar Eclipse – Part 2

Last week I posted about my pre-eclipse experience. Today’s post has photos of the eclipse itself. I used my bridge camera (Canon Powershot SX70 HX) on a tripod with a solar filter for most of them. Both my skill and camera improved since the 2017 eclipse when I was using a Canon Powershot SX730 HS with the same filter. I compose my shots such that the camera stays in  P (program) mode and autofocuses. The only setting change made was the +/- exposure compensation during totality.  My ‘best shots’ for the 2024 eclipse included:

Two areas of sunspots (pre-eclipse)

First contact

Further along

Only one sunspot still visible

Frown in the sky

Diamond ring (no filter)

Baily’s beads and solar flares/prominences (no filter)

More solar flares/prominences (no filter)

Corona (no filter)

Nearing the end of totality (no filter)

Diamond ring (no filter)

Smile in the sky

I took one picture with my phone holding my solar glasses over the lens after totality. I was klutzy to hold…but worthwhile to try.

My husband had an app running that was providing prompts leading up to totality…when to remove filters…the mid-point of totality…filters back on. It was good to have the audio rather than having to check the time some other way. He had a more complex set up with several higher end cameras – one of which had automated tracking (which didn’t work quite the way he expected). These were his three favorite totality shots.

The road trip home was prolonged with heavy traffic. A lot of people traveled to see the eclipse, and all were heading home afterward at about the same time. We stopped for dinner along the way and the traffic cleared a little. It was a long day for us: leaving home at 5:30 AM and returning at 9:30 PM. It was worth it!

Gleanings of the Week Ending April 13, 2024

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.

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.

The Art and Architecture of Ancient Egypt

W. Stevenson Smith’s The Art and Architecture of Ancient Egypt was published in 1958 and is available on Internet Archive. It has 192 black and white plates which are well worth browsing. There are familiar images of Egyptian artifacts/ruins, but the ones I enjoyed the most were either new-to-me or a different view of something familiar.

For example, the different perspective of the Ramses II statue and Tutankhamon’s chair and chariot drew my attention (click on the sample images to see a larger version).

Many statues and smaller items like axe heads were shown large enough to make out details. It is also evident that the author included images of artifacts from many museums.

The architecture of ancient Egyptian sites is shown at locations and via reconstructed versions (models and drawings).

Enjoying browsing the images that are grouped after the text of the book! Research and excavation continue in Egypt so keep in mind the vintage of this book.

Solar Eclipse – Part 1

We traveled from our home near Springfield MO to Poplar Bluff MO for the solar eclipse on April 8th. There was a flurry of activity on the day before the event to finalize our destination; the weather forecast was the key driver for us to choose Poplar Bluff (along with Whitely Park being a good location that was not included as part of the event planning by the city).

We left our house at 5:30 AM to pick up our daughter and son-in-law before heading east; it wasn’t long before sunrise. I took some pictures of it through the windshield of the car (my husband did all the driving).

We did not encounter any heavy traffic during our morning drive…got to the park 2 hours before the first contact…plenty of time for set up and looking around the park. We set up on an asphalt parking lot that never completely filled up so we spilled over onto the two spaces on either side of where we were parked next to a fenced soccer field.

I walked around to look at a few low growing plants…

And trees that were just beginning to leaf out. I realized that the trees did no have enough foliage to make projected crescent patterns onto the ground as happened when we were in Loup City, Nebraska for the August 2017 solar eclipse.

On the ground – I noted roots of a sycamore, seed pods of sweet gums (from last year and green ones from this year) and a clump of green (probably a weed) surrounded by brown thatch.

There were birds about:

Two purple martin houses that were beginning to be populated. One had a pair of house sparrows too; I wondered how long it would take for the purple martins to evict them.

A starling in the grass – keeping an eye on the sky.

And a group of robins in a tree without leaves but lots of twigs that made it hard to get a good image.

I took most of my eclipse pictures with my bridge camera (Canon Powershot SX70 HX) on a tripod with a solar filter taped to the camera body to cover the lens until totality). I had eclipse glasses that I wore to look at the sun with my eyes and put over the camera on my iPhone to take one picture. I’ll post my eclipse pictures on Sunday along with some my husband took…stay tuned for that.

Then and Now

The is the first post in my Then and Now series that will include my reflections on my ‘growing up decade’ (the 1960s) and now. A lot has changed over those 60 years, and I’ve found myself thinking more about it recently – maybe prompted by my mother’s death or me being 70 years old. Choosing these decades leaves out my career almost entirely – only the perspectives of preparation for it in the 1960s and reaping the benefits from it now in my post-career years.

I was 6 to 16 years old in the 1960s …remembering vivid snippets primarily about friends, family, and school…and a few events in the news (the assassination of John F. Kennedy in 1963 and a tornado that I saw through my school window before the sirens went off on April 3, 1964). In the 1960s I assumed I had a long life ahead of me; now I assume that it will take more and more focused effort on my part to remain healthy and enjoy the years left in my life. The way I live now definitely has roots that began developing in the 1960s!

The posts will focus on a particular aspect that has changed and will come out weekly on Monday mornings. Stay tuned….

Gleanings of the Week Ending April 6, 2024

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.

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.

Gleanings of the Week Ending March 30, 2024

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.

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.

Fine Art History (collection on Internet Archive)

This ‘book of the week’ post introduces a collection found on Internet Archive that features slideshow collections of art works from artists from around the world and different time periods. There is a lot to browse in this collection and I will probably feature it again from time to time since I enjoy the images and learning about the artists. I have chosen 5 for this first post…hopefully the sample images will provide enough of an incentive to take a look at these artists and the rest of the collection.

Springfield Botanical Garden – March 2024

Springfield Botanical Gardens is one of my favorite places; I will try to go at least once a month for the rest of this year. We went on a sunny cool day in the late morning. The sky was almost clear and the light was very bright….making for some ‘almost high key’ pictures of the blossoms on a tree growing close to where we parked.

There were other trees/bushes in bloom as well.

The maples were already making seeds (i.e. past blooming). The seeds were still colorful.

Spring bulbs were still blooming….

But I was more interested in the new growth all over the hosta garden. It will be very lush this summer.

I took some pictures of the garden mosaic…carefully avoiding getting my shadow in the picture.

Lenten roses were blooming. My daughter has some in her yard too. They do seem to grow well but I tend to not like them because their blooms face downward.

There were birds in the gardens too. Lots of robins. We heard a brown thrasher and then saw it high in the tree….too high for a good picture. I did get a picture of a blue bird though!

My husband was very tolerant of my walking around to take pictures even though he didn’t see anything he was interested in photographing. He seemed very intent on macro photography….and didn’t see any opportunities. I find that the zoom on my bridge camera (Canon Powershot SX70 HS) is good enough to take some ‘almost macro’ pictures without being close to the flowers (or birds) at all!

Sustaining Elder Care – March 2024

A recap: My sisters and I started our journey ramping up elder care back in November. At first we thought we were being proactive in our conversation about ‘next steps’ with my parents’ doctor….but, less than a week later, my mother was critically ill and in the hospital. I spent the next 7 weeks in Texas. My mother managed to recover enough to come home before Thanksgiving even though she needed a lot of support at home. We hired caregivers to assist her at night through December and moved my parents to an assisted living group home just before the new year. As we worked to get them settled into the assisted living routine, we started a surge of effort to get their house cleared and on the market; the sale was finalized at the end of February. Both parents responded favorably to assisted living and decided they wanted to go out to eat occasionally rather than having special meals via take out as we had done for them at their house. In mid-February, they became sick with COVID…my dad first; he got Paxlovid and was recovering. My mother tested positive a few days later; her doctor adjusted her meds and she got Paxlovid; at first her case seemed even less symptomatic than my dad’s; the staff at the group home thought her breathing was wheezy one afternoon (even though my mother did not think she was having breathing problems) and sent her to the hospital via ambulance; she died 2 hours later.

The last few weeks have been busy ones. We reconfigured my dad’s living space from two rooms down to one and are in the process adjusting the assets my mom and dad accumulated to support his long-term care. As I write this, I realize that we have already settled into a ‘sustaining’ rather than ‘ramping up’ mind set. It isn’t that we won’t evolve what we do based on my dad’s needs…but we have a framework that will stay the same: the assisted living group home…daily visits from family….out to eat several times a month…walking in the neighborhood when the weather is good. Right now, he is still adjusting to not having mom around all the time; she was there for him for over 71 years. We are grateful to the staff of the assisted living for their increased attention. He still has times when he looks lonely…but he is talking more than he did when mom was around to talk for him.

Going forward, my trips to Texas will be quick ones – drive down and visit with dad in the afternoon before I head to my hotel, drive home the next day. Sometimes I will visit with dad in the morning before I drive back. I have done 2 of these trips so far in March. My sisters are there more frequently because they live closer than I do – one is there almost every day, another comes 2-3 times per week, another once or twice a week. Along with taking him out to eat, we put out his clothes for the next day, work on a puzzle with him, accompany him on a walk, help him find something that he lost (his wallet with his id and he glasses tend to go missing).

My sisters and I have had conversations about how much we have accomplished in the past few months – having to adjust very rapidly. We are not exactly relaxed at this point, but the stress level is dramatically lower!

Gleanings of the Week Ending March 23, 2024

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.

6 chemical stories of colors through time – A little history of these colors….some very toxic!

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.

Warming Waters Bringing More Sharks to the Alabama Coast - Globally, warming waters are driving sharks to new areas where they were previously scarce. Great white sharks, tiger sharks, and bull sharks have all edged northward. From 2003 to 2020, the number of juvenile bull sharks swimming through Mobile Bay rose fivefold.

Arctic Sculpture

The 4 eBooks for this ‘books of the week’ post are from Canadian Arctic Producers Co-operative published in 1980 and include sculpture from Inuit artists in 1979-1980…grouped by village. I enjoyed the figures of the Arctic as a place and culture.

Pangnirtung, recent sculpture

Igloolik, recent sculpture

Clyde River sculpture

Coppermine : Sculpture

 I found these 4 eBooks by accident but recently did a comprehensive search for the publisher and found a lot more books so there are more to browse – which I will do over the coming months! These books are a great way to become more familiar with modern Inuit art. There is a Wikipedia entry for the Co-op too.

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.

Annual stick/pinecone yard clean up

The chiminea left by the previous owner of our house comes in handy for burning sticks and pinecones that would otherwise be difficult to get rid of. The sticks come mostly from our neighbor’s river birch (the tree sheds into our side yard every time we have a strong wind!) but there is a mixture of crape myrtle and oak….and some branches trimmed from the forsythia last season that were thoroughly dried in their pile under a pine tree. The first two fires were all sticks! Most of them broke into short enough pieces easily enough but a few poked out the opening of the chiminea until they burnt enough that I could slide them the rest of the way in. The mornings were cool enough that I enjoyed watching the fire burn. My husband asked why I smelled like smoke when I came inside!

As I trimmed some lower branches off our largest pine, I realized that there were way too many pine cones and that I was going to need to burn some of them – particularly the ones that had fallen onto grass rather than the carpet of needles directly under the tree; otherwise the lawn mower was going to be challenged by them every time I mowed in the upcoming months.

I piled the cones into a wagon along with the forsythia sticks (which had broken easily into short lengths) and loaded the chiminea with the sticks and half the cones for the third fire of the season. I lit a paper towel wadded under the sticks to start the fire.

It was an interesting fire to watch. The forsythia sticks and most of the cones caught fire easily although some of the cones might have been damp enough to slow their burning. As the fire progressed, I enjoyed the movement of the flames…the shape of the cones and the way they changed from their brown color to black with glowing red crescents to black and white…and then ash. I added the rest of the pinecones once most of the initial load had burned….and they caught quickly. After they had burned down, I stirred the ashes and was surprised at the chunks that still hadn’t burned. I closed the screen on the chiminea and watched the fire die before I went inside – realizing how much I had enjoyed photographing the pinecone fire.

Gleanings of the Week Ending March 16, 2024

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.

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.
