Rare ‘Doomsday’ Oarfish Surfaces in California, Just the 20th Discovered in the State Since 1901 - Usually lives as far as 3,280 feet below the surface. Scientists conducted a necropsy, but they couldn’t discern a reason for the elusive fish’s death. Scientists aren’t totally sure why oarfish and other deep sea-dwelling creatures sometimes surface, but they suspect the animals may be disoriented, sick or injured.

Owl-Inspired “Bionic” Fan for EVs Reduces Fan Noise 50% While Improving Efficiency 10% - Making EVs even quieter!

Do you have knee pain from osteoarthritis? You might not need surgery. – Article written by researchers in Australia about the updated treatment guidelines for knee osteoarthritis that stress exercise, increasing physical activity, weight management, and pain medication (in moderation and not opioids). The links at the end of the article include an online exercise program specifically for knee osteoarthritis.

Frank Lloyd Wright’s Only Skyscraper Set to Close Amid Controversy – Price Tower in Bartlesville, Oklahoma. Built in 1956. Designated a National Historic Landmark in 2007.

Rebuilding the Genome of Woolly Mammoths - Typically, ancient DNA fragments yield short snippets of DNA and provide an incomplete picture of the genomic puzzle. However, the woolly mammoth skin sample showed promise. The team assembled the first 3D reconstruction of the woolly mammoth’s genome, which had 28 chromosomes; the order of genes was very similar to that of the Asian elephant. They discovered: the specimen was female; differences from modern elephants in the genes related to hair follicle development and, more broadly, hair maintenance; cooling and dehydration can preserve the molecules in their original locations.

Homelessness – From Our World in Data. Interesting…but frustrating too. I was glad that they emphasized when the data is not consistently collected…and the analysis gets very tricky.

Only One Country Is Making Progress on Electrifying Everything – Unfortunately it is not the US…it’s China. The country that electrifies most rapidly and builds the most renewables to power its electrified economy will be the most competitive economy globally.

As Arctic Thaws, New Evidence of Looming ‘Mercury Bomb’ - Scientists estimate that the amount of mercury in the atmosphere has grown sevenfold over the last 500 years, primarily from burning coal. Air currents are carrying airborne mercury toward the Arctic, where it is absorbed by plants, which then deposit the toxin in the soil. Over centuries, mercury has built up in the frozen ground, such that today, Arctic permafrost may hold more mercury than the atmosphere, the oceans, and every living organisms combined. As the region warms, melting permafrost could liberate this buried mercury.

Rare Fossils Give Clues to How Tardigrades Survived Mass Extinctions by Hitting the Snooze Button - Tardigrades are known for being some of the most resilient animals to exist, capable of surviving extreme temperatures, pressure, radiation and starvation—they can even withstand exposure to outer space. Only four known fossils of tardigrades have been found to date, and all of them are preserved in amber, or ancient tree resin; recently they were reanalyzed using confocal fluorescence microscopy. Cryptobiosis is the secret to tardigrades’ incredible resilience, and it appears to have evolved in two tardigrade linages (at least). In survival situations, these hardy creatures will expel the water from their bodies and suspend their metabolism almost completely allowing them to outlast unfavorable conditions of their environment.

Five ways the brain can age: 50,000 scans reveal possible patterns of damage - Results could lead to methods that detect the earliest stages of neurodegenerative disease. Dementia and its precursor, mild cognitive impairment, had links to three of the five patterns. Intriguingly, the researchers also found evidence that the patterns they identified could potentially be used to reveal the likelihood of more brain degeneration in the future. Other patterns were linked to conditions including Parkinson’s disease and Alzheimer’s disease, and one combination of three patterns was highly predictive of mortality.

How Storm King Art Center Became One of World’s Top Sculpture Parks – Adding to my list to consider seeing if I travel to New York (state).

Dirt Cheap Batteries Enable Megawatt-Scale Charging Without Big Grid Upgrades Right Away – Hope the technology trend continues…that this idea helps us transition to more electric trucks and other vehicles.

Extreme Birding: Shorebirds at the Sewage Lagoon – Maybe a great place for birding….if you can stand the smell. The same thing happens at landfills.

The human brain has been shrinking – and no-one quite knows why - The brains of modern humans are around 13% smaller than those of Homo sapiens who lived 100,000 years ago. Exactly why is still puzzling researchers. I was a little surprised that the authors did NOT consider the challenge of birthing babies with larger heads (i.e. until C-sections allowed mother and baby to survive if the baby’s head was too large, both mother and baby died) which would result in natural selection of genes for smaller heads.

Climate change is most prominent threat to pollinators - Pollinator populations are declining worldwide and 85% of flowering plant species and 87 of the leading global crops rely on pollinators for seed production. The decline of pollinators seriously impacts biodiversity conservation, reduces crop yield, and threatens food security. Changes in water and temperature associated with climate change can lower the quantity and quality of resources available to pollinators, decrease the survival of larvae or adults, and modify suitable habitats.

The deep ocean photographer that captured a 'living fossil' – In 2010, Laurent Ballesta was the first diver to photograph a living coelacanth. In 2013, Ballesta and his team returned and encountered multiple coelacanths, spending up to half an hour in their presence. Thanks to Ballesta's work, we now know the coelacanth is among the longest-living fish species, with a lifespan of around 100 years, and has one of the slowest life histories of all marine fish – so, like deep-sea sharks with a reduced metabolism, the coelacanth grows slowly, taking as long as 69 years to reach sexual maturity, and with a gestation period of around five years.

Under stress, an observer is more likely to help the victim than to punish the perpetrator - It takes more cognitive effort to punish others than it does to help them. Studies show that when witnessing an act of injustice while stressed, people tend to behave selflessly, preferring to help the victim than to punish the offender.

Stunning Aerial Photos Capture the Abstract Beauty of Iceland’s Glacier Rivers – Iceland….blue.

These tricks make wind farms more bird-friendly – Migratory birds can crash into wind turbines…but there are ways to reduce the carnage: adding high visibility reflectors and spirals to cables, not building wind farms in flight paths, painting one blade on each turbine black (or stripes of black on each blade), and sound.

Swarms of miniature robots clean up microplastics and microbes, simultaneously – Interesting idea. While the bots were decontaminated and reused…they were not as effective…so more work is needed.

Then and Now – Heating

During the 1960s, the heating where I lived in Texas transitioned from electric wall heating to gas powered central heating. Both had to work harder because the windows of the houses were single paned and had little insulation. I remember that my grandparents’ houses were often colder in the winter than mine was. My paternal grandparents’ farmhouse had gas burning (probably propane) stoves in each room and my maternal grandparents’ house had gas burning (probably natural gas) floor furnaces; in those houses, the kitchen during meal prep time, was the warmest! Prior to the advent of thermostats, the controls on the heaters were tweaked manually.

My house now has two central heating furnaces (2 zones) – one natural gas and one electric. Within the next 5 years, we will be transition to electric powered heat pumps. The house has well-sealed doors and double pained windows….and was well insulated when it was built in 1999. It has two gas fireplaces which we haven’t used; the gas is turned off and we have sealed the vents with magnetic strips to stop the drafts in the winter. We have a ‘smart’ thermostat that we can program to change the temperature at different times during the day; since we are retired, that is usually letting it cool down a bit at night while we are sleeping.

In general, modern heating systems and houses, make it easier to feel warm in the winter. I wonder sometimes if that changes the early years of children’s lives. For example – a baby born in December would be learning to walk a year later. Prior to central heating, that would mean more clothes to get in the way during that process than a child born in July would have as they learned to walk. Did mothers of winter babies keep them close to their own bodies to make sure they were warm (i.e. did winter babies get held more in their very early lives)? Central heating might have made early childhood development more consistent because it took away much of the seasonal variation experience for babies!

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.

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.

Settling in, developing new routines – 8th month

We moved to Missouri eight months ago and have adjusted in many areas…but there are still things to do. My previous ‘settling in’ posts were made in the 1st, 2nd, 3rd, and 4th month; it’s time for another update. The upheaval of the move is waning. The changes between our 4th month and now are more gradual; there isn’t the frenzy of activity like in the first few months. We’ve voted in the mid-term election, subscribed to a local news feed… are experiencing winter and working on our 2022 tax filing (it is more complex this year with the sale of a house and two state taxes). I’ve sustained my treks to Texas; it’s become apparent that the monthly plan might need to be adjusted quickly depending on the care my parents need; the priority of being available for my parents will keep me from signing up for volunteer gigs or university classes. Our three kittens are keeping us close to home too; they need a lot of attention but we have successfully done day trips and 1-2 nights away; my daughter checks on them when we are gone for more than a few hours.

There are still things we are anticipating:

Spring in Missouri. The rhododendron flowers were already fading by the time I first looked at the house…the irises had already bloomed too. I’ll enjoy seeing the flowers…supplemented with the additional bulbs I planted last fall. We are also talking about day trips for gardens and birding hotspots within the state.

All-electric. We are talking more about the order of steps we will take to move the house toward being ‘all-electric’ over the next 3 years or so…and then adding solar panels/battery.

Dark sky. My husband is keen to go to a dark sky site…hopefully once the temperature is a bit warmer, he’ll be able to do it.

Yard. I have been putting off contacting a nursery…but need to do it soon if I want things in before it gets too hot (and potentially dry) this summer.

Overall – we are not venturing out very much right now because of the cold…but we’ll do more outdoors in the spring. And maybe meet more of our neighbors too!

Milk packaging influences its flavor – Light blocking containers are best….and plastic/glass is better than paperboard. So why aren’t paperboard cartons being phased out (they are also harder to recycle than plastic milk cartons).

Clean Energy Saw as Much Investment as Fossil Fuels for the First Time in 2022 – Good! And hopefully this will continue to be the case…and we don’t allow any fossil fuels to be counted as ‘clean.’

What Secrets Lie Beneath This 17th-Century French Aristocrat’s Smile? – Decaying teeth and an ivory prosthesis (in front) held in place with gold wire….and a woman kept her smile and place in society.

A curious Colorado bear strikes a pose for 400 selfies on a wildlife camera – A bear that noticed the camera!

Leprosy: the ancient disease scientists can’t solve – There is treatment…but diagnosis is complicated and there is no cure. And we still don’t know how it is transmitted.

Researchers find rare 17-pound meteorite in Antarctic ice – A team spent a week and half in the Antarctic summer (14 degrees Fahrenheit…so still very cold) sleeping in tents and riding snowmobiles to search for meteorites. They found small ones….and a big one!

New mosquito repellents that work better than DEET – Maybe the next generation mosquito repellent?

In 2021, 20% of electricity in the US was generated from renewable sources – And wind surpassed hydroelectric in 2019 as the predominant renewable source. Hopefully, the percentage of electricity from renewables will go up quickly in the coming years.

Three grizzly bears tested positive for avian flu in Montana - The animals were euthanized in the fall; suspected to have rabies, they tested negative. But they were positive for avian flu. The bears were ‘in poor condition and exhibited disorientation and partial blindness, among other neurological issues.’ So – the current outbreak of avian flu that has impacted wild and domestic birds (more the 52 million have been killed or culled to contain the virus) is impacting more than birds.

Drone video of moose shedding its antlers – Wow – it happened so quickly; the video is only 16 seconds! The moose just shakes its body, and the antlers fall off. It seems to want to leave the scene quickly once they are off too.

How do snowflakes form? Is each snowflake really unique? Why is some snow light and fluffy or heavy? The amazing science of snow – A good topic to explore in the winter! The article includes a video of snow and ice crystal growth.

Falling birth rate in US not due to less desire to have children – People are not having as many children as they say they want, especially at earlier ages. There is some evidence that people reduce the number of children they intend to have as they get older. They may realize how hard it is to have and raise kids in the US…and decide to only have one child rather than two. They may have more challenges conceiving as they get older too. Larger economic and social forces are also impacting birth rates.

Meditation and mindfulness offer an abundance of health benefits and may be as effective as medication for treating certain conditions – An overview of the strengths/weaknesses of studies about mediation/mindfulness…a good introduction.

Drone Photography Celebrates the Beauty of Historic High-Rise Buildings in the U.S. – Wonderful views of the highest parts of tall buildings.

9 in 10 drivers in the US would save money on fuel by going electric – Good! Hopefully the cost of the electric cars will come down a bit…and we’ll have more models to choose from…and the places to charge them during road trips will be convenient.

Why obesity is more dangerous for men – Evidently men have a lot more inflammation associated processes and don’t grow as many new blood vessels in their fatty tissue.

See the Lavish Pompeii Home Owned by Two Men Freed from Slavery – Reopened after 20 years of restoration work. It was originally excavated in 1894-1895.

Broccoli looks more like cauliflower in a warmer world – Looking at the chemistry behind the changed growth of broccoli at higher temperatures…avoiding the change in the lab…but will it enable us to still produce broccoli that looks like broccoli as the planet warms?

Another step toward an insulin tablet - A lot of diabetics would appreciate ‘no more injections’!

Why Electrifying Everything Is a Critical Pathway to Decarbonize The World & Our Lives – I like these articles that get specific about the options that individuals/families can take. It gives me more hope for my future and the future of the planet to take the actions I can to 1) decarbonize the electricity used by my home, 2) move toward an all-electric home and transportation, 3) improve efficiency/reduce waste, and 4) sequester carbon. Focusing on the ‘all electric’ concept this week. I have natural gas powered heating and hot water heater…will probably replace the heating/cooling first. The gas fireplaces are turned off already – removing them is not a high priority.

Utilities

My husband made the arrangement to transition of utilities from the previous owner to us in our Missouri house. The water, sewer, electric, gas and trash/recycle were all with the city…easier than in locales where each one is separate.  

We thought that maybe the internet/cable connection would take longer, but we got an appointment for the day after closing! What a relief to have that taken care of before I made the whirlwind trip back to Maryland!

It seems like the process was easier than when we moved to our Maryland house 25+ years ago…a positive experience.

Now to wait a month and see how we do on electric usage with the air conditioner keeping the house comfortable during the summer heat. The gas usage during the summer is only for hot water so should be at the lowest for the year.

Can cloud seeding help quench thirst of the US West? – New research on an old idea…many states increase their use of the technology.

Fresh water from thin air – Another technology that might help dry regions….using hydrogels (like the ones currently used in diapers!).

What’s The Construction Industry Blueprint to Cut Carbon? – I wanted more specific examples…was a little disappointed that this article did not provide them, but maybe that would have made it a long article! I hope to see more on this topic.

Higher education must reinvent itself to meet the needs of the world today. Enter the distributed university – The pandemic has highlighted the challenges the current higher education model is facing. The ideas in this post are a start but don’t seem to be fully developed to push into full implementation. More work needs to be done to enable transition from the existing model to a new one that is more responsive to the needs not only of undergraduate students but for graduate students and continuing education. The sources of money in the current model don’t match up well. For example – in the US the sports programs (football) is a big money maker for many universities; how does that map into the new model (or do we want it to).

Upcycling plastic waste into more valuable materials could make recycling pay for itself – Hope this research can be transitioned into commercial use….we have to improve the recycling processes that are being used today. Too much is still ending up in landfills.

Fossil pollen reveals the African origins of Asia’s tropical forest – Research on Borneo’s Dipterocarps (very large trees with buttress roots, smooth/straight trunks, high crown) using fossil pollen reveals their origins in Africa…spread through India before it crashed into Asia…and then to Southeast Asia. The forests in India shrank as the climate became drier. These trees need a wet, seasonal climate to survive.

Mummification in Europe may be older than previously known – Analysis of bodies found in Mesolithic shell middens in Portugal reveal that they were probably mummified before being placed there 8,000 years ago. The description of the way the researchers came to that conclusion was interesting…a lot has been learned about forensics since the 1960s when the bodies were originally found. The oldest intentional mummification known before this finding was from the Chinchorro hunter-gatherers living in the coastal region of the Atacama Desert in shell middens (around 7,000 years old).

Lake Powell Reaches Lowest Level Since 1980s – The drought continuing in the west….

The myths and realities of modern friendship – Thought provoking. The ways we communicate with each have changed a lot over my lifetime!

The climate math of home heating electrification – The rationale for moving to heat pump heating/cooling as quickly as possible.

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

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.

Why do we hate trash birds? – A little about the way we dismiss birds we see frequently (maybe too frequently) and the difference in the birds viewed that way in the US and Australia. The Australian white ibis is nicknamed ‘bin chicken’! Here in the US, some people think of pigeons and Canada geese and mallards as ‘trash birds.’

Flu and heart disease: The surprising connection that should convince you to schedule your shot – Flu vaccines save lives…particularly lives of people with heart disease. An improvement the article suggests: make sure cardiologists stress the need to get the flu vaccine to their patients – not just assuming the primary care doctor will do it.

AAA: Vehicle auto safety systems often fail when driving in heavy rain – I’ve observed this several times but is the first time I’ve seen the recommendation to ‘avoid using cruise control in wet and slippery conditions.’ The cars should probably provide warning messages more overtly to not rely on certain driver aids in bad weather.

By 2500 Earth could be alien to humans – The projections of models used now are out to 2100…that is not far enough into the future. We can’t assume that we’ll succeed in reversing climate change by that time…or maybe we are collectively so pessimistic right now that we think the world will end by 2100.

How to make sustainable choices for a long life and a healthy planet – A summary of some recent studies on health/diet choices and the relationship to climate change. It turns out that it’s pretty easy to eliminate some of the most unhealthy items like soft drinks and foods with lots of sugar. It’s a learning experience to shift to meals to plant based protein…for me – it’s still a work in progress.

The plastic recycling system is broken – here’s how to fix it – I agree that it is broken…but I’m not sure that what is suggested in the article would be enough. We need packaging solutions that are not plastic at all! I have tried to eliminate as much single use plastic as I can since even with perfect recycling, I’m not sure I want things like food to be in plastic packaging (how can we know that the plastic is safe for food). There are so many items that you can’t buy without plastic packaging. The consumer is forced to be part of the problem even if they want to be part of the solution.

How a simple tummy-rub can change babies' lives – Maybe baby massage techniques should be incorporated in all baby care courses, videos, and books!

7 underrated creepy creatures – A little hold-over on the Halloween theme.

From Homes to Cars, It’s Now Time to Electrify Everything – My existing house has a gas hot water heater and furnace; the other appliances are already electric and I drive a plug-in hybrid which means that most of my around town driving is in an EV. But I don’t have solar panels. My plan is to move in the next year or so and quickly arrange for solar panel installation and transition the house to be all-electric. Next step would be the addition of battery storage. I’m also intrigued by the idea of a wind wall (see next item on the gleanings list).

This ingenious wall would harness enough wind power to cover your electric bill – This could be something that would work for more homes and businesses than solar...particularly if they were relatively inexpensive to produce. There is an aesthetic appeal too.

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.

Listening to Silence: Why We Must Protect the World’s Quiet Places - Yale E360 – I realized after 9/11 that most of the modern world sounds at my house are from transportation: planes/helicopters and cars/trucks with occasional yard equipment. While we had a stay-at-home order with this pandemic, it became noticeable as well. There are still times when those noises are subdued or gone. I notice the bird songs in the early morning…when the other sounds don’t intrude. As we skew more toward electric ground transportation….the noise level will notch downward. I enjoy the natural sounds a lot more than our man-made ones.

Declining eyesight improved by looking at deep red light -- ScienceDaily – I wonder if this is something doctors will start prescribing!

Why your organs might reach 100 even if you don't - BBC Future – A summary of some current research areas re aging. There are a lot of different approaches with the primary goal of most being to extend healthy lifespan.  Even if different organs age at different rates…they are interrelated to the body they comprise.

Maryland offshore wind farm could become stop-over for migrating sturgeon, striped bass -- ScienceDaily – I live in Maryland….so this story grabbed my attention. Will the offshore windfarm become a rest stop for fish? And they will offer a convenient infrastructure for researchers to collect data.

Where Will Climate Migrants Go? – THE DIRT – It’s something to think about now. Some coastal cities are already experiencing more flooding even without unusual storm events…and people that can move will probably do so. Will climate trends weigh in decisions about where they move? The article talks about cities and towns in the Midwest that have experienced declining population becoming ‘receiver’ locations. I wondered if people that have discovered that they can work from home during the pandemic – and can continue to do so – will be freer to move to these new locations and still have the same employer! Otherwise there is the challenge of how to sync moving to a new place with a new job.

The chemistry of cats: Allergies, catnip and urine – Compound Interest – Evidently male cats produce higher levels of allergen and have smellier urine…unless they have been neutered.

Ways to keep buildings cool with improved super white paints -- ScienceDaily – White roofs should probably become the norm….it will be hot enough without the added heat island effect caused by a lot of man-made structures with dark roofs.

How humans are altering the tides of the oceans - BBC Future – It’s happening around the world. Dredging river channels and filling in coastal wetlands cause shifts in how tides interact with the land. And then there is sea level rise too. Some places cited in the article that have experienced dramatic change: Cape Fear River in North Carolina (tidal range at Wilmington has doubled since 1880) and the same is true for St. Johns River/Jacksonville Florida. Sacramento’s tides disappeared in the late 1800s because of silt but dredging brought them back and the Thames tidal range was 2 meters during Roman times and 8 meters by the Victorian age.

Meet the Mountain Chickadee – We have mostly Carolina Chickadees where I live in Maryland…this is their relative in the western US (mountains).

Ancient Maya reservoirs contained toxic pollution: Mercury, algae made water undrinkable in heart of city -- ScienceDaily – Mercury from pigments used on Mayan building. Cyanobacteria blooms that made the water smelly and toxic. Not pleasant for a city center!

Unique Activities for Yesterday:

Regenerative Landscaping lecture (via zoom). The lecture was about an hour and my big take away was about the huge environment cost of lawns…and the many dimensions of that cost. The one I hadn’t thought much about before was from the California Air Resources Board fact sheet on Small engines in California (small engines being spark-ignition engines in things like lawn mowers). Their fact sheet says: “In the early 2020s, however, total smog-forming emissions from small engines are projected to exceed those from passenger cars in the South Coast Air Basin because passenger car emissions will continue to decrease. By 2031, small engine emissions will be more than twice those from passenger cars.” For comparison – they show 1 hour of lawn mowing emits as much smog-forming pollution as driving a Toyota Camry 300 miles! This must be an issue in all areas where there is a lot of mowed turf grass – kike most suburbs. There are multiple ways to address the problem and the one discussed in the meeting was transitioning to less lawn or lawn that does not need to be mowed as frequently (or at all). Another way would be to transition to electric mowers and other yard equipment. Right now – the only gasoline powered equipment I have is the mower. I’d been thinking about an electric mower because I don’t like the noise and smell of our current machine. So - this overall air quality issue is just one more reason to do it.

Enjoyed a slideshow of Armand Guillaumin (1841 – 1927) paintings available on Internet Archive here. He was a French impressionist painter and lithographer.

Clifford E. “Bill” Hall Park in Carrollton

The Bill Hall Park is a neighborhood park within walking distance of my parents’ house in Carrollton, Texas. It was developed just as their youngest grandchild was ready to enjoy it (he’s now in his 20s) so my mother thoroughly explored it with him. There has a playground and path through the small woods.

I chose a sunny day to walk over…passing under the electric towers right-of-way on a sidewalk.

There were dandelions blooming and going to seed on a berm behind a retaining wall near one corner of the park.

It hasn’t been cold enough this year to cause grass to go dormant or weeds to die back.

There was a small plant growing in one of the retaining wall drains that was wet (most of the others were dry) and had accumulated soil.

The park is surrounding by houses now, but it was once a farm and some of the rusted equipment is still around. The tree has grown around this rusting piece!

As I walked along the paved path through the woods, a group of blue jays made a ruckus. At first I thought they were reacting to me….but it was a hawk. They chased it through the woods. The tail had black and white bands…so not a red-tailed hawk. Maybe a red-shouldered. DFW Urban Wildlife has them second on the list of hawks seen in the DFW area.

Gleanings of the Week Ending December 30, 2017

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.

Top 25 Wild Bird Photographs of the Week #118 – National Geographic Society – As usual – I can’t resist bird pictures. So many birds….all around the world.

Learning Center Classes and Field Excursions — North Cascades Institute – I’m adding this to my list of places to check out when I get round to planning a vacation in the US Pacific Northwest.

Ancient Maya Heritage Comes Alive...With Some Help from Google and the British Museum | Smart News | Smithsonian and the Preserving Maya Heritage Site – Be prepared to spend some time with the second link if you are interested in Mayan culture at all.

The Woman Who Shaped National Geographic – A short biography of Eliza Scidmore….writer and photographer.

Shutdown of coal-fired power plant results in significant fetal health improvement in downwind areas -- ScienceDaily – A study close to home…a power plan in Pennsylvania…the health impact happened down wind of the plant in New Jersey. An example of the need for multi-state studies (and Federal involvement) …and another reason to reduce generation of electricity using coal-fired plants.

NASA Unveils Finalists for Its Next New Frontiers Mission | Smart News | Smithsonian - A mission to Saturn’s moon Titan (from Applied Physics Lab) and a sample-return mission to a comet (from Cornell). Both projects will be funding through the end of 2018…then one will be chosen.

Bees use invisible heat patterns to choose flowers -- ScienceDaily – Heat pattern on such flowers as poppies and daisies can be 4-5 degrees warmer than the rest of the flower!

BBC - Future - Educationism: The hidden bias we often ignore – Some idea on how to improve: acknowledge that bias exists and use assessment as a tool for education (how to improve) rather than for selection. It turns out that many factors beyond an individual’s control can hinder potential.

Tiny red animals dart in the dark under the ice of a frozen Quebec lake -- ScienceDaily – A surprise for winter researchers – previously the assumption was that everything was on hold during the winter.

Five Surprising Ways Your Christmas Tree Can Give Back Long After the Holidays – Cool Green Science – Maybe there are other things to do with a ‘real’ Christmas tree after the holiday.

Three things to know about the Louvre’s history – A fort…royal residence…and then a museum!

Americans are using less electricity today than a decade ago – Annual residential electricity sales have declined by 3% and residential electricity sales per capita is down by 7% since 2010. Advances in efficiency and shifts to smaller devices are making a difference. Some argue that electric cars will cause an increase in demand for electricity….but the same people that drive electric cars are likely to have solar panels!

Aspirin’s Four-Thousand-Year History – Willow bark was used for 1000s of years for ‘curing’ fevers. In 1897, Felix Hoffman at Bayer created chemically pure salicylic acid and then created acetylsalicylic acid which did not irritate digestion the way salicylic acid does….and Aspirin came to the marketplace.

The Quest to Restore American Elms: Nearing the Finish Line – My grandparents had elm trees around their house in Oklahoma when I was growing up in the ‘60s. My grandfather built a picnic table around one of them and we had our evening meals there during our summer visits. In my late teens, the tree began to die and eventually had to be cut down. The place lost a key element when that happened. I’m sure that was true around many homes. I hope the elms can be restored….and maybe the chestnuts too.

Climate change is disrupting the birds and the bees and Europe to experience vast and rapid ‘invasion’ by infectious diseases as climate warming continues – The effects of climate change are not just rising temperatures or changing weather patterns. Everything on earth is interrelated. Sometimes that building in resiliency to change and sometimes it enables small changes to have a domino effect that is catastrophic.

In the Earth’s hottest place, life has been found in pure acid – Microbes that survive in extreme acid, hot temperatures, and high salinity. The pH in one pool was 0…and life was found there.

Here’s a crazy idea: let’s agree on the facts – Finding common ground through data? That is what Steve Ballmer is working on. The USAFacts site is the result and it is very easy to spend time looking at the summary reports….and the linkage to raw data sources.

It’s not your imagination. Summers are getting hotter. – A graphic of the changing bell curve of the temperatures with the base period being 1950-1980…crawling toward the hot and hotter direction for the time periods since them.
