Gleanings of the Week Ending September 9, 2023

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.

Extreme Weather is the “New Norm” - There is high confidence that human induced climate change from greenhouse emissions, is the main driver.

A Visit to North America's Only Authenticated Viking Site - L’Anse aux Meadows National Historic Site (in Newfoundland), the only authenticated Viking site in North America. Credit for this discovery in the 1960s goes to Norwegian explorer/writer Helge Ingstad and his archaeologist wife Anne Stine.

Earth’s hottest month: these charts show what happened in July and what comes next – The intense heat this summer has killed Saguaro cactus!

Ötzi the Iceman’s Genome Sequenced – 90% of his ancestry came from Anatolian farmers. Genome analysis revealed he had high skin pigmentation, dark eyes, and male pattern baldness!

Common wristbands 'hotbed' for harmful bacteria including E. coli, staphylococcus – I am glad the band on my Garmin is metal since it likely harbors a lot less bacteria than a plastic, rubber, cloth, or leather band. However, I still need to get in the habit of cleaning it more often.

Fully Intact Giant Panda Skeleton Discovered in Chinese Emperor’s 2,000-Year-Old Tomb – There was also an Asian taper in the tomb.  The article suggests that perhaps the animals were included in the tomb as a part of a replica royal garden.

Medications for chronic diseases affect the body's ability to regulate body temperature, keep cool - Medications used to treat common chronic conditions, like blood thinners, blood pressure drugs, Parkinson's disease/Alzheimer's medications, and some chemotherapy drugs, can make it harder for the human body to handle hot weather by reducing its ability to sweat or increase blood flow to the skin. Hopefully doctors will become more aware of this issue – particularly for their elderly patients that are already at increased risk because of their age for heat related issues.

Trapped: Australia’s extraordinary alpine insects are being marooned on mountaintops as the world warms – The grasshopper with the turquoise exoskeleton snagged my attention. This movement up mountains and then becoming marooned must be happening around the world.

Chromium replaces rare and expensive noble metals – Osmium and ruthenium replaced with, much more abundant, chromium? More research is needed, but it might be possible.

Photos of the Week – August 13, 2023 from the Prairie Ecologist – Another example of enjoying some photography even when it is hot and humid!

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.

An effective new treatment for chronic back pain targets the nervous system – A 12-week course of sensorimotor retraining had a positive effect and participants reported improved quality of life one year later (i.e., the relief was lasting). Hopefully the results can be replicated, and the treatment applied to a broader population. There are a lot of people with chronic back pain!

New Study Links Cat Hormones and Gut Microbiomes to Their Social Behavior – Hard to resist a cat story!

Millions of Americans have long COVID. Many of them are no longer working – 4 million full-time equivalent workers out of work because of long COVID (conservative estimate…and that 2.4% of the US working population). There is a push to provide accommodation in the workplace but some of the symptoms are so severe that the person cannot perform the work they did before and maybe too disabled to work at all. No wonder unemployment is low, and some jobs are not finding applicants. Because long COVID is new, it is unclear when, or if, this population will recover enough to re-enter the workforce.

Arche Roach: the great song man, tender and humble, who gave our people voice – An obituary – and history of aboriginal people in Australia over the past century or so.

The promise and danger of Scotland's bog – 80% of the UK’s peatlands are degraded and in deteriorating condition. They store a lot of carbon…motivating restoration efforts. It takes decades to reverse damage done in a short time by a few ditches and a grid of planted saplings.

New molecule may prevent age-related diseases and increase life expectancy and wellness – A group of molecules that enable cells to repair damaged components has been identified….and efficacy was demonstrated in a model organism. The researchers and Hebrew University’s tech transfer company are moving toward pre-clinical studies.

Parts of the moon have stable temperatures fit for humans – Pits and caves that stay roughly 63 degrees Fahrenheit! There are still big challenges for living on the moon: growing food and finding sufficient oxygen, for example

Coming wave of opioid overdoses 'will be worse than it's ever been before' – Fentanyl and carfentanil…combined with methamphetamines and cocaine. The accelerated rates of overdoses are happening everywhere according to a Northwestern Medicine study.

Inside King Tut’s Tomb – New research using the tomb walls to understand the real-world turmoil cause by the death of the young king.

Cocoa shown to reduce blood pressure and arterial stiffness in real-life study – Cocoa flavanols only decrease blood pressure if it is elevated! I enjoy my morning dark chocolate (70+% cocoa) squares…a healthy way to begin the day!

Gleanings of the Week Ending July 30, 2022

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.

Furs from Danish Viking Burials Analyzed – Proteins extracted from animal furs found in 6 burials. The accessories/furnishings were domesticated animals. The items of clothing were wild beaver, squirrels, and weasels. The beaver furs were not native to the area so were probably luxury furs obtained by trade.

More Energy on Less Land: The Drive to Shrink Solar’s Footprint – Good ideas…if we must use agriculturally productive land for solar panels. I’d like to see cities with high density solar panels that generate electricity close to where it is needed (i.e., short distance between generation and use). Hopefully that is happening in parallel with the solar development described in this article.

Moths are unsung heroes of pollination – The study was done with red clover…but probably applies to a broader range of plants. Moths are active during the night so have not been as easily observed as pollinators that are active during the day. The work was done with time lapse cameras.

Electric School Buses! – A blog post about the US Department of Energy’s ‘Flipping the Switch on Electric School Buses’ series. There are lots of communities that have been exploring making the transition and I am hopeful that it will be an escalating trend. I always cringed at the fumes that were so obvious when the buses arrived/departed from schools as I was growing up and when my daughter was in school. It would be good for the planet and good for children’s lungs to eliminate the school bus as a source of air pollution!

The habits that help prevent allergies – Studies that are improving our understanding of why allergies are increasing in the children….and strategies for addressing the problem. Evidently the time between 4 and 11 months is very important.

Harm from blue light exposure increases with age, research in flies suggests – Not good news. Maybe the default setting on our ‘screens’ (phones, computers, television) need to reduce blue light rather than it being a setting that everyone must intentionally set. And why don’t LED manufactures offer bulbs that are not so blue shifted?

Giant Snails take over Florida’s Gulf Coast - It is not the first time…probably won’t be the last. These snails are native to Africa and this the third time Florida has battled an invasion.

Water resources to become less predictable with climate change – The study focused primarily on areas that rely on snow for all or part of their water supply. Some of those areas are already relatively dry…and the populations are large enough that the unpredictability of water resources will be very problematic.

The best way to brush your teeth – This is going to take some practice to break old habits. I learned to brush my teeth a long time ago and probably am too sloppy even doing it the way I was taught!

New thought on Cahokia’s ancient wetlands – A large flat rectangular area that was previously thought to have been used as open, communal space might have been under water most of the year!

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.

Tallgrass Prairie National Preserve: A windo into the past – A prompt for an early fall road trip? It is about 4 hours from where we live now.

Psoriasis: Study lays foundation for new treatment strategy – Hope more targeted treatment can be developed….avoiding the drugs used currently that suppress the immune system overall.

Winners of the 2022 Audubon Photography Awards Celebrate the Beauty of Our Feathered Friends – Images of birds in action.

The silent danger of gum disease – More reasons to sustain regular dental checkups….and for dentists to be vigilant.

The Milkweed Gang – Milkweed attracts quite a few insects…even if it is an island surrounded by invasive plants!

New species of giant waterlily is the largest in the world – It has been growing in Kew Gardens in 177 years and in a herbarium in Bolivia for 34 years….always assumed to be the well-known species of giant waterlily named after Queen Victoria. The leaves can grow up to 10 feet wide…and support at least 176 pounds!

Toads surprise scientists by climbing trees in UK woodlands – Even when we think we know a species well…there are still surprises!

This New Species of Carnivorous Pitcher Plant Traps Its Prey Underground – In the rainforest of Borneo at elevations of 3,600 – 4,265 feet.

Ozone Hole — New, Large, Constant Ozone Hole — Appears Over Tropics – 7x larger than then Antarctic ozone hole!

Unlocking the secrets of the ancient coastal Maya – More than a decade of interdisciplinary work increasing the understanding of how these people lived and responded to rising sea levels and changing political/economic systems. And still more to be learned.

Ten Little Celebrations – April 2022

April was a whirlwind month---with more than the usual amount of drama because of our plan to move to Springfield, Missouri. More than half the little celebrations I selected for the month have to do with the move:

Finding a house we liked and getting it under contract. It was new (and high anxiety) to do the contract with only seeing it virtually…thrilling to do the walkthrough to confirm that it was THE HOUSE for us.

A good driving day is always welcome, but we particularly celebrated one of the days heading home; perhaps a sunny, spring day is balm to the stress of the drive and the anticipated events of the next few months.

Home again is always something I celebrate. This time I savored the house that has been home since October 1994…realizing that soon I would be transferring the joy of homecoming to a new place.

Initiating contact then selecting movers. This was not a single day event, but I was pleasantly surprised at virtual inventories and other options. There are some things that have changed for the better since my last long distance move in 1983.

22 boxes packed in one day. I set a goal for myself to pack 20 boxes a day for a week and I achieved that goal! I celebrated the most on the highest day (22 boxes).

There were other things to celebrate in April…

Early morning at the grocery store. I love the quiet at the store before 7 AM with spring far enough along that it is light at that time…but still full of morning color.

A medical test that found nothing. Sometimes finding nothing is worth celebrating…particularly as we get older.

No traffic on the Bay Bridge. We made a 2-day trip to the Eastern Shore (birding field trips) and celebrated that we didn’t have traffic on the bridge – coming or going.

No traffic on the Bay Bridge. We made a 2-day trip to the Eastern Shore (birding field trips) and celebrated that we didn’t have traffic on the bridge – coming or going.

A wealth of birds. There were 4 field trips over 2 days…and we celebrated that we saw so many birds – some species in larger numbers than we had ever seen before. Stay tuned for blog posts coming next week.

Japanese Garden. I enjoyed our visit the Mizumoto Japanese Stroll Garden in Springfield MO although the celebration came afterward as I looked at my pictures (too noisy from the mowers while I was in the garden).

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.

Study recommends six steps to improve our water quality – The study focused on nitrogen pollution.

The cells that give you super-immunity – Memory B cells were first discovered in the 1960s….but there is still a lot we are learning about them as we analyze the data from the COVID-19 pandemic.

Chicken Frenzy: A State Awash in Hog Farms Faces a Poultry Boom – Ugh! Hope North Carolina can figure out how to keep their groundwater and waterways from being polluted. It’s a beautiful state and it saddens me that the intensive hog and poultry production has not developed technology to be friendly to their immediate environment….or any place that is down stream from where they are located.

What’s the Weirdest Animal Courtship? Here Are 4 Candidates – A post that came out on Valentine’s Day.

Heart-disease risk soars after COVID – even with a mild case – Heart disease was already one of the chronic conditions common for a lot of people in later life… now with COVID, the numbers of people are going to increase and the age demographics are skewing younger.

Enhanced forensic test confirms Neolithic fisherman died by drowning – A skeleton from a 5,000-year-old mass grave on the coast of Northern Chile was analyzed with methods used for more recent bones to determine if a person drowned in salt water….and the method worked!

The mysteries of the Ponderosa Pine – The complex relationships between the health of pine forests and: birds, low-severity fire, squirrels, mushrooms, and carbon storage. Forests are complex!

The science of healthy baby sleep - A little history…and the bottom line: there is NOT just one correct approach to how infants should sleep.

Feeling dizzy when you stand up? Simple muscle techniques can effectively manage symptoms of initial orthostatic hypotension – There might be more validation that needs to be done across a wider demographic range…..hope this happens and if it works for a wide range of people so that doctors can immediately start encouraging their patients that have initial orthostatic hypertension (IOH) to use the simple moves before and immediately after they stand up.

Do you know the world weirdest wild pigs? – The post includes 5 of the 18 wild pig species. The only one in North America is the Africa Red River Hog – one was caught in a trap set for feral hog control in Texas (2019); there are evidently Texas game ranches advertising ‘hunts’ for red river hogs which indicates they have been intentionally imported and there has been at least one escapee from one of those ranches! Is there a free-ranging population of African River Hogs reproducing in the wilds of Texas?

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 the Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

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.

Wind Energy Accounted for 42% of New US Power in 2020 – And solar was 38% of the new energy. And 8 east coast states have large offshore wind projects in the works in the years ahead. Hurray! It’s a good trend and it looks like the slope of the trend will keep increasing for wind and solar (decrease and go to 0 for new natural gas).

How people respond to wildfire smoke -  Another reason to slip on a mask.

Devastating Rain in Tennessee – A map of the change in soil moisture between August 20 and August 21. The floods on August 21 in Tennessee (area circled on the map) killed at least 22 people. I was surprised that there was an area of Illinois (to the north and a little west of the flash flood circle) where the soil moisture increased even more; perhaps that area floods frequently and the area is managed with flooding in mind.

New analysis reveals Vesuvius Victims’ diverse diets – From analysis of Herculaneum skeletons. Men got more of their protein from seafood. Women ate more meat grown on land, eggs and dairy products.

Eye provide peek at Alzheimer’s disease risk – Amyloid plaques can form in retinas of the eye. Does their presence there provide a visible biomarker for detecting Alzheimer’s risk?

Top 25 birds of the week: Wild Birds! – Bird photography…..challenging and beautiful subjects for our cameras.

Have you seen a weasel lately? – There is a suspicion that weasels are in the decline…but the data is circumstantial. These are not predators that have been widely studied. The post points to a role for citizen scientists!

Dispatches from a world aflame – Reviews of two books about the recent fires…and the relation to climate change.

Preemption of Green Cities in Red States – At a time when we need to get serious about addressing climate change – a drive by some states to keep local governments from taking any action. There is a cognitive dissonance between historically arguing for local control then usurping that control when the state government does not agree with it. I like local control but acknowledge that higher up the governance hierarchy could make sweeping changes easier. Perhaps some of these state governments will redeem themselves by quickly taking strong action toward climate change reduction and mitigation – soon. The top issue for me when I vote these days has become climate change!

Climate Change Is The Greatest Threat To Public Health, Top Medical Journals Warn – Another reason that actions to address climate change must be at the forefront of our thinking about the future. Medicine cannot make up for the injury we are making to ourselves and every living thing on the planet.

Night Sky Celebrations Across the National Park System – We’re not doing this kind of traveling this summer….but maybe we’ll do several of these ‘star parties’ in summer 2022.

Tooth loss associated with increased cognitive impairment – Another reason to not neglect going to the dentist! It’s not just about preserving cognitive impairment either….quality of life is a big motivation as well.

Top 25 birds of the week: Seabirds – From around the world…a few I’ve seen in North America.

Mucus and mucins may become the medicine of the future – There is still a lot to learn about how this might work….but it appears that this is an opportunity to treat disease by enhancing the mechanisms already used by the body. Maybe one of the first uses will be for eye drops to treat eye infections rather than the antibiotics used today.

Protect Pollinators – reform pesticide regulations – Hopefully the action requested by these scientist from around the world will happen…our ecosystems are having enough challenge dealing with climate change. Many pollinator species won’t survive the continued threat of status quo pesticide use.

Keeping your composure: Creative Ways to Compose Your Photographs (part 1, part 2, part 3) – Always good to browse through these kinds of tutorials…pick up some new ideas, celebrate the things you are already doing.

What to do with food waste? – It doesn’t appear than there is any one strategy that will work broadly. I’m glad I have already dramatically reduced food waste and then have a large enough yard to have a compost bin.

Waterfalls of North Carolina – A few years ago, my husband and I made a waterfall themed trip to New York. It seems that North Carolina would be another state that has a lot of opportunities for waterfall photography. Maybe next spring?

Creativity Myths – A recent ‘letter’ on The Painter’s Keys website.  I enjoy the twice-weekly blurbs that appear in my inbox (free subscription) and often follow the ‘click here to read more’ link.

Exposure to light with less blue before sleep is better for energy metabolism – I already change the color balance on my PC screens to ‘nightlight’ between sundown and sunrise. Maybe we will do more eventually based on this and subsequent research. It is probably true that no one should be watching a television screen just before going to bed!
