Gleanings of the Week Ending October 28, 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.

Water Worker Stumbles Upon 2,500-Year-Old Gold Necklaces in Spain – Celtic gold….from before the Roman Empire ruled the Iberian Peninsula.

Canopy gaps help eastern hemlock outlast invasive insect – Hemlock wooly adelgid killed most of the hemlocks in the part of Maryland where I lived previously. Perhaps part of the reason so many died was that they were in forests where there were too few gaps in the canopy around them.

Germany to Surpass 50 Percent Renewable Power This Year – Good milestone but evidently Germany is still not on pace to reach its goal of 80 percent renewable power by 2030.

The surprising origin of a deadly hospital infection - The burden of C. diff infection may be less a matter of hospital transmission and more a result of characteristics associated with the patients themselves (i.e. patients that are already colonized with C. diff were at greater risk to transition to infection). However, it is still unknown what triggers the transition from C. diff hanging out in the gut to the organism causing diarrhea and the other complications resulting from infection.

Meet the Bison: North America’s Most Famous Mammal – Lots of info on bison…their history of almost being hunted to extinction.

The secret world of rhododendrons: a plant more ancient than the Himalayas that inspired fables and stories around the world - There are around 1000 species in total, and modern DNA-based work confirms that all “azaleas” are in fact species of rhododendron.

A Sign of Things to Come? After Last Ice Age, Europe Cooled as the Planet Warmed - More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change.

Fiber from crustaceans, insects, mushrooms promotes digestion – Chitin (from insect exoskeletons and mushrooms) activates the immune system and benefits metabolism. Insects are not on my menu….but I could eat mushrooms more frequently. The researchers plan to follow up to determine whether chitin could be added to human diets to help control obesity.

Review of over 70 years of menopause science highlights research gaps and calls for individualized treatment - Less than 15% of women receive effective treatment for their symptoms. Socio-economic factors such as lower quality of life and the potential negative impact of menopausal symptoms on a woman's work performance aren't often acknowledged. Therapy should be individualized depending on age and health risks, recognizing that health risks may increase with age.

California and Florida grew quickly on the promise of perfect climates in the 1900s – today, they lead the country in climate change risks - In California, home owners now face dangerous heat waves, extended droughts that threaten the water supply, and uncontrollable wildfires. In Florida, sea level rise is worsening the risks of high-tide flooding and storm surge from hurricanes, in addition to turning up the thermostat on already humid heat. Global warming has put both Florida and California at the top of the list of states most at risk from climate change. These futures bring into question how historic visions of economic growth and the sun-kissed good life that California and Florida have promised can be reconciled with climates that are no longer always genial or sustainable.

Archaeologists Uncover Hundreds of Colorful Sarcophagi at Saqqara—and They’re Not Done Yet – The seeming endless interest in Egypt…sustained by continuing new finds.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

Winners of Wildlife Photography Competition Show the Power of Water – Starting out the gleanings list with some eye candy this week.

Personality traits are associated with well-being and satisfaction in life after work – My husband and I have transitioned to ‘life after work’ and seem to have easily established ‘new fulfilling life patterns.’ In an odd way, the COVID-19 pandemic has helped us focus on the most important aspects of those patterns.

A New Study of the Permian Basin – a US oil-drippling hotspot is kicking out far more methane that we thought – I keep thinking that the technology to reduce emissions in the fossil fuel extraction process has improved from the early days. Maybe it has…maybe the hasn’t. The industry may not be motivates. Is it all about maximizing profits for them and their stockholders…everyone else doesn’t matter?

Toad Wisdom – A story of webs of life from the Prairie Ecologist.

European earthworms reduce insect populations in North American forest – Even small invasive species can have a significant impact.

Mapping Inequality – Redlining in New Deal America – An introduction….then downloads and data for maps for urban areas across the US from the 1930s.

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.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory.  A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.

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

The great experiment to put a price on nature – Whether it’s toting up ecosystem services or simply realizing that Mother Earth is our one and only…we should all realize that we need to start taking care of ‘nature’ a lot better than we have in the past.

Microplastics May Be Impacting the Climate, Study Finds – A starting point for combining climate science and microplastic science into a model….still a lot if refinement/additions. We already know that the microplastics in our atmosphere are increasing so whatever impact they have it will likely be increasing during the time the model is being refined.

Ancient Stone Ram Heads Unearthed on Egypt’s ‘Avenue of the Sphinxes’ – New finds…and part of an advertisement for some restored places reopening in early November. Are tourists ready to travel again to places like Egypt?

Spending time in nature promotes early childhood development – A study from metro Vancouver of 27,372 children from birth to age 5… that pushes us to get serious about making sure spaces for children include a lot green space…that includes day care and preschools and K within the age range for this study. And while we are doing that – let’s think about how important green space is to everyone else too.

Meet the muskrat: push-up champion of cattail marshes – This article made me wonder if muskrats eat phragmites – and a plant that is taking over marshes. I found an article that says they do…at least in some situations.

Changing ocean currents are driving extreme winter weather – Looking at the impact of the slowing Atlantic Meridional Overturning Circulation (AMOC) and extreme cold weather (like in Texas last February) using a high-resolution global climate model. They’ve only done the simplest model (turning off the AMOC) so far…but plan to refine it to address the more complex reality.

Finding Fall Colors At Bandelier National Monument – I hope everyone found someplace to enjoy fall colors these past few weeks. My main opportunities were in my own backyard and as I was driving down the highway between Maryland and Texas!

Cheers! Wine’s red grape pulp offers nutritional bounty – Not compost or fodder...getting more than wine from vineyards!

Hit the sleep ‘sweet spot’ to keep brain sharp – Evidently 5.5-7.5 hours of self-reported sleep is about right.

2021 EPSON International Pano Awards Celebrate the Creativity of Panoramic Photography – Enjoy some eye candy as the last of this week’s gleanings!

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.

Self-controlled children tend to be healthier middle-aged adults -- ScienceDaily – Benefits include younger brains and bodies, better outlook in the years ahead. This finding is from a study done in New Zealand with 1,000 people tracked from age 3 to 45 (i.e. they were born in 1972 and 1973). Hopefully they will continue to be tracked as they get older….to determine if they remain healthier as they age. The finding makes sense to me based on my observations of my own life and people I have known over many years.

An Invasive Wild Edible Winter Rose – Natural History Society of Maryland – Multiflora rose…it’s a plant that takes over – climbing over everything around it…and it is prickly. One redeeming quality might be the RoseHips that can be used to make tea. Birds eat them too and that propagates the plant – so maybe more harvesting by humans would reduce this invasive!

College campuses are COVID-19 superspreaders, new study suggests -- ScienceDaily – My daughter and son-in-law are very aware that this could happen at the university where they teach and have research teams. They are offering blended classes so that students can be in person or virtual…and providing higher quality masks for their themselves and their research teams.

The 'megascale' structures that humans could one day build - BBC Future – Some history and observations…the realization that there are existing ‘megascale’ structures: terracing of parts of Southeast Asia, land reclamation from the sea by the Netherlands, the internet, the US Interstate Highway system.

SolarEV City concept: Building the next urban power and mobility systems: Unlocking the potentials of EV batteries with roof-top PVs for urban decarbonization -- ScienceDaily – Calculations done for 9 Japanese urban areas…CO2 emissions in these urban areas could be reduced by 53-95%!

The state of the climate in 2021 - BBC Future – Looking at CO2, record heat, Arctic ice, permafrost, and forests. We need to make progress toward drawdown rather than continuing actions that cause the upward ramp of planetary warming.

Are monarchs in trouble? | Science – In my area of Maryland…the decline has been dramatic.

A Tweak to Immune Cells Reverses Aging in Mice | The Scientist Magazine® - Interesting but so far has not be translated into humans. Evidently a drug to specifically block the EP2 receptor is not easily developed.

Tiny hard drives that are alive — and multiplying : Research Highlights – Experiments with data encoding in the E. coli genome. Evidently the data is protected from degradation in the presence of dirt and other contaminants…but what about changes that would occur over many replications?

Top 25 birds of the week: February 2021 – A grand finale to the gleanings….bird photographs!

Doing Something About Global Warming Is Cheaper Than Doing Nothing – I selected a series of gleaning for this week that are focused on various aspects of climate change – with a mix of perspectives. This is the first one. For the pure capitalists…this one makes the argument for action in their terms. This first article came out back in September…so it is a little dated…but still makes some good points.

The daring plan to save the Arctic ice with glass - BBC Future – Do we want to consider Geoengineering?

40% of O'ahu, Hawai'i beaches could be lost by mid-century -- ScienceDaily – Sea level rise…and our response to it.

6 Graphics Explain The Climate Feedback Loop Fueling US Fires – Some good graphics about the fires on the west coast of the US. In recent days, fires in Colorado have been added to the news. At a time when forests sequestration of carbon is important for the health of the planet….the fires are reversing that benefit.

Natural Debate: Do Forests Grow Better With Our Help or Without? - Yale E360 – Hurray for natural regeneration – unless the land is too degraded for that to be possible…then our help is needed.

The Best Places for Solar Power If You Want to Clean The US Grid – Where investing in solar power would do the most toward reducing grid emissions…by state.

Unique Activities for Yesterday:

A busy morning. The only extra activity I’d planned yesterday morning was to get my car washed since the dirt road into the CSA is history for the year. The car is cleaner (at least on the outside) than it has been for months! The weather was so great when I got back that I swept the leaves from the driveway, street gutter, and deck onto the yard so that the mower would mulch them when my husband mowed later in the day. When I got back inside – I noticed my husband had called from the vet parking lot saying his battery was too low to start his car (and the vet had resolved the cat’s bleeding claw issue)….so I was off to help that car situation. We managed to get home just in time to cook lunch. The level of activity was greater than any recent morning (months and months of mornings!) …and I felt a little discombobulated! I’ve begun to enjoy the pace of pandemic life!

Shrinking of Utah National Monument May Threaten Bee Biodiversity | Smart News | Smithsonian – Grand Staircase-Escalante is home to 660 bee species, 84 of which live outside of protected land under changes. At a time when we know pollinators are under stress…one more reason why our Federal lands are needed as refuges from human activities that damage the environment.

Scientists Don't Stay for Long in Their Jobs Anymore: Study | The Scientist Magazine® - About half of scientists who enter a scientific discipline drop out after 5 years; in the 1960s, it was 35 years. We are probably training more people in science fields but many don’t stay in academia. This study used publishing records to determine if a person stayed ‘in the discipline.’ I’d prefer to see numbers of people that had careers in a STEM related field rather than just the one they trained in and find another metric than published papers to make the determination. There are a lot more jobs today where people use their science training that do not use ‘publication’ as a measure of success.

BBC - Future - Can we cheat ageing? – Some areas of active research to help us stay healthy longer (may or may not help us live longer).

Corn Domestication May Have Taken Thousands of Years - Archaeology Magazine – It all started 9,000 years ago in southern Mexico. The process continued in Mexico and the southwestern Amazon for several thousand years. It was a slow process.

Only 12 percent of American adults are metabolically healthy, study finds: Trends help sound alarm for efforts to lower associated risk of types 2 diabetes, heart disease and other complications -- ScienceDaily – Not a good statistic since the long term risks of diabetes, cardiovascular disease and other serious health issues are higher for those that are not metabolically healthy.

Rethinking Raw Milk, 1918 | The Scientist Magazine® - Alice Evans and the path toward avoiding milk borne diseases. Her work was published in 1918. Draft ordinances for states and localities to implement pasteurization requirements for milk to be consumed by humans were written in 1924. The first federal pasteurization law was passed in 1947…saving lives and millions of dollars in public health costs.

With Shorter Winters, Plants Bloom Early and Die Young – National Geographic – Green springs…but the plants don’t sustain the green through the drier summers. Not good for our yards and our farms…and us.

Photo of the Week – October 19, 2018 – The Prairie Ecologist – Fluffy seeds from the prairie…including common milkweed,

Image of the Day: Clubbing | The Scientist Magazine® - Peacock Mantis Shrimp have a spring-like structure that enables them to beat the life out of their prey.

Beautifully Painted Shrine Emerges from the Ashes of Pompeii | Smart News | Smithsonian – Much of Pompeii that we know from tourist books was excavated before modern methods…and sometimes ‘restored’ in a way that we don’t know exactly what it looked like when originally uncovered. New excavation can provide clues about older excavations as well as the particulars of the newly uncovered walls.

Substantial changes in air pollution across China during 2015 to 2017 -- ScienceDaily – Particulates are down but ozone is up….so good and bad trends.

BBC - Future - The flu that transformed the 20th Century – The 1918 flu epidemic…100 years ago this year. There is still research on the virus and what happened…some surprises in the findings.

Lighting intervention improves sleep and mood for Alzheimer’s patients: Daytime light exposure decreases sleep disturbances, depression and agitation -- ScienceDaily – I wonder if this is not true for almost everyone…not just Alzheimer’s patients. Artificial light (and computer/tablet/phone screens) are disruptive to our circadian rhythm.

Majority of Americans Believe Space Exploration Remains Essential | Pew Research Center – Hurray! The result that surprised me the most in this survey, was that ‘monitor key parts of the Earth’s climate system’ was the top priority!

Photographer Captures the Enchanting Beauty of Mount Fuji at Dawn – I expected more sunrise color…but enjoyed the artistry behind these images more than I initially thought I would.
