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.

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

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

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

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

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

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

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

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

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

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

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.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

Kitchen chemistry hacks explained – How many of these did you know before this article? I knew about lemon juice slowing browning of fruit…I’m going to try the ‘brown onions more quickly’ and ‘chop onions more comfortably.’

Top 10 Things You Didn’t Know About Distributed Wind Power – Interesting update….and map of annual average wind speed at 30 m. There is so much potential in the center of the country. It would be interesting to see the map extended offshore…but maybe that kind of wind power is only used for wholesale generation rather than distributed wind power.

Dust: how the pursuit of power and profit has turned the world to powder – A review of the book about ‘tiny particles doing terrible things’ created by detonation of nuclear weapons, burning coal, and drying of lakes via irrigation. These tiny particles influence our environment, our health, and our relationship with the world around us. They move around the planet through the air…no one is ‘safe’ from them.

More small airports are being cut off from the air travel network. This is why - A shortage of pilots is partially to blame for major airlines' departure from smaller airports. But changing airline economics means the challenge facing regional airports could become insurmountable. Williamsport PA is the example used in the article.

Health evidence against gas and oil is piling up, as governments turn a blind eye – An Australian perspective…but seems to be applicable to many developed countries, including the US. The methane leaks, water contamination, air pollution…why do we continue to push for gas and oil development rather that pivoting to cleaner (and renewable) sources?

Wyoming and Utah Borderlands – A picture from the International Space Station. I remembered a trip to Utah in 2008 where we drove in the area with a Roadside Geology of Utah book explaining the surface geologic features!

New research explains 'Atlantification' of the Arctic Ocean – Changes coming in the Arctic as a 15-year cycle is ending….and the next phase could result in a faster pace of sea-ice loss.

Stone Case Holding Precious Items Found at Templo Mayor – 15 stone figures found at the temple complex of Tenochtitlán, the capital of the Aztec empire. The figures may have already been 1,000 years old when the Aztecs conquered the Mezcala people that carved them. Also in the case: two rattlesnake-shaped earrings, more than 180 green stone beads, snails, shells, and marine corals.

Workers like it when their employers talk about diversity and inclusion - Research has shown that diversity, equity and inclusion (DEI) initiatives improve creativity, innovation, productivity and organizational performance. One of the reasons DEI initiatives have a positive impact is because workers appreciate them. It’s about making sure everyone feels valued and included.

What Does It Take to Photograph a Bat Cave? – Photographer Stephen Alvarez….lots of specialized photographs.

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.

Air Pollution Causes 1 In 6 Human Deaths – Deaths from modern pollution risk factors, which are the unintended consequence of industrialization and urbanization, have risen by 7% since 2015 and by over 66% since 2000. Unfortunately, little real progress against pollution can be identified overall, particularly in the low-income and middle-income countries, where pollution is most severe. It is increasingly clear that pollution is a planetary threat, and that its drivers, its dispersion, and its effects on health transcend local boundaries and demand a global response.

Opioids no more effective than placebo for acute back and neck pain – The study was done in Australia but, hopefully, will lead to stepping away from opioids for back/neck pain. How many became addicted to opioids via doctors writing prescriptions trying to relieve their patient’s back pain?

Antimicrobial Resistance: The Silent Pandemic – The first accounts of antimicrobial resistance (AMR) occurred 2 years after Alexander Fleming warned about it in his 1945 Nobel speech. AMR is now responsible for nearly 700,000 deaths worldwide each year, and it is projected to kill 10 million per year by 2050.

Early Women Were Hunters, Not Just Gatherers – My favorite statement from the article: “Grandmas were the best hunters in the village.”

Overdose deaths involving street xylazine surged years earlier than reported – Drug death data is gathered and analyzed slowly…not so long ago, it appeared that illicit xylazine use was still largely concentrated in the mid-Atlantic states and the Northeast….but it is not showing up in street samples all across the US and surging in the South and West. US drug deaths hit a new record last year with roughly 110,000 fatal overdoses nationwide from fentanyl and increasingly complex street drug cocktails.

U.S. Wind and Solar Overtake Coal for the First Time - In the first five months of 2023, wind and solar produced 252 terawatt-hours, while coal produced 249 terawatt-hours, according to preliminary government figures. The decline in coal is happening faster than anyone anticipated.

Largest-ever atlas of normal breast cells brings unprecedented insights into mammary biology – 12 major cell types, 58 biological states…differences based on ethnicity, age, and the menopause status of healthy women.

Why our voices change with age – Lots of reasons the sounds we make can change. One habit suggested from the article that I am considering: “Singing or reading out loud daily can give the vocal cords sufficient exercise to slow their decline.”

Cedar Breaks Wildflower Festival Starts Friday – Hmmm…maybe I should look for wildflower festivals (along with birding) when I plan our vacations.

Meltwater is hydro-fracking Greenland’s ice sheet through millions of hairline cracks – destabilizing its internal structure - Earth’s remaining ice sheets in Greenland and Antarctica are far more vulnerable to climate warming than models predict, and that the ice sheets may be destabilizing from inside. Recent studies have shown that:

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.

Environmentally friendly ways to cool homes – This will be an increasingly ‘hot’ topic for individuals and various levels of business and government. Many electrical utilities are already seeing increased energy consumption during the summer.

What’s Up with White Squirrels and Black Squirrels? – I haven’t seen any white squirrels but we have the occasional black one in our neighborhood (in Maryland).

Medical errors keep killing patients – but there are laws, incentives and mindset changes that could reduce the death toll – Medical mistakes are s leading cause of death, behind heard disease and cancer. This should not be the case. Surely incentives can be used to force changes to the unacceptable status quo.

Deaths linked to ‘hormone disruptor’ chemical costs billions of lost US productivity – A study that included more than 5,000 adults ages 55-64 done by NYU Grossman School of Medicine. The people with the highest concentrations of phthalates in their urine were more likely to die of heart disease than those with lesser exposure. I am no longer storing food in plastic containers unless they phthalate free…the bigger problem is cosmetics/hygiene products. It’s hard to know which ones have it.

Why are you seeing lots of vultures now? – Our area has resident turkey and black vultures…we see a few all year long. In the fall we might see an uptick because of vultures from further north migrating through.

Mushroom consumption may lower risk of depression – Yet another reason to enjoy mushrooms in your diet!

US Moving Towards 30% Electricity from Wind & Solar – By 2026! That is not that far away. I know I’ll probably have solar panels on the roof of my house well before that (and probably some energy storage as well).

Possible Mammoth Butchery Site Found in Arctic Circle – On an island off the northern coast of East Siberia. At the time the animal was killed (26,000 years ago), sea levels were lower, and the island was connected to the mainland.

Nature-based activities can improve mood and reduce anxiety – A metastudy that looked at 50 studies and 14,321 NBI records done by the University of York. Interestingly – they didn’t find that the activities improved physical health!

It’s Time to Ban Gas-Powered Landscaping Equipment – We already have some electric landscaping equipment: blower, trimmer, weed eater. The mower will be next. I am looking forward to it since I notice the exhaust smell and get a scratchy throat every time I mow.

How to Easily Catch Spotted Lanternflies Using a Water Bottle – These insects have invaded Maryland, but I haven’t seen them yet. Maybe this is a reason to put an empty plastic water bottle in the car – just in case.

Exposure to deadly urban heat worldwide has tripled in recent decades, says study – On of the topics in the schoolyard field trip for 6th graders was heat islands – it’s a good example of the impact of climate change around the world.

Smoky Clouds That Form Over Wildfires Produce Less Rain – Drought…forests burning…and then less rain. Aargh!

8 Fall Nature Experiences to Enjoy – There are so many things to enjoy in the outdoors during the fall – as the heat of summer fades away.

Exploring The Parks: 10 Historic Sites To Visit This Fall – More ideas for fall activities. I’ve been to all the sites they list that are on the east coast…but not necessarily in the fall.

NASA and USGS Launch Landsat 9 – The first Landsat was launched in July 1972 – the year my husband and I graduated from high school.

A new solid-state battery surprises the researchers who created it – Solid state electrolyte and an all-silicon anode – faster charge rates at room to low temperatures. There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!

Yale Climate Change Maps 2020 – Results from a spring 2020 poll about climate change.

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.

Human egg cells are imperfect surprisingly often -- ScienceDaily – More than 7% of human oocytes contain at least one exchangeless chromosome pair…and the frequency is not affected by maternal age. Our species is hardwired to have significant numbers of miscarriages and babies with extra or missing chromosomes. The finding is interesting, but I immediately thought of some questions…has this changed over the past 100 years (i.e. have we changed our environment enough that we are impacting our reproductive success) and how does this frequency compare to other mammals?

Why our pursuit of happiness may be flawed - BBC Future – A thought provoking piece about how seeking ‘happiness’ often sets the stage for disappointment…rather than contentment.

Pollution from cooking remains in atmosphere for longer -- ScienceDaily – Eating deep-fat fried foods is not just unhealthy…the cooking of foods that way contributes to air pollution. In London, 10% of the PM2.5 particles are from deep fat frying….in Hong Kong 39%!

2nd Annual Threatened And Endangered Parks: Natural Darkness And Sounds – My husband and I are looking forward to more dark sky opportunities in national parks. So far – the ‘star parties’ we’ve been to have been at state parks and hosted by amateur astronomy clubs in the area. The dark sky venue requires a bit of infrastructure to support a field full of camping amateur astronomers with their telescopes (electricity for telescopes/computers and bath rooms with red tented windows).

U.S. Breaks Record for Billion-Dollar Climate Disasters in 2020 | Smart News | Smithsonian Magazine – Not a good record to be breaking…and they happened during a pandemic year too. There were 22 disasters that caused at least $1 billion in damages across America in 2020.

Q&A: Global Insect Declines Due to "Death by a Thousand Cuts" | The Scientist Magazine® - In every case researched….it’s not just one thing that caused the decline…it a cluster of primary factors (6 or more) and then other factors that are difficult to quantify.

Texas Wind Power Dominates Coal In Crossover Year – Hurray! Hopefully, the coal plants will begin to phase out in Texas and across the country as they become less and less competitive with renewable sources of power.

On the road to invisible solar panels: How tomorrow's windows will generate electricity -- ScienceDaily – I am always reluctant to consider replacement windows….but if they were cost effective solar panels…that would tip the decision toward ‘buy’!

Critically endangered South American forests were planted by ancient peoples -- ScienceDaily – Forests of monkey puzzle trees were cultivated for their nuts and ability to attract game….they expanded as the population grew between 1,410 and 900 years ago. That was after an earlier expansion of the tree’s range caused by wetter climate from 4,480 and 3,200 years ago.

NASA Study Says Freshwater Shortages Will Be Biggest Challenge of This Century | CleanTechnica – As population increases along with industrialization and farming….more fresh water will be needed. We cannot afford to damage the supply beyond recover or use it unwisely.

Most popular vitamin and mineral supplements provide no health benefit, study finds -- ScienceDaily – Lots of studies say that food is the best way to get vitamins and minerals….this one goes a step further. It found that the supplements provide no health benefit!

Mapping America’s Aging Population - CityLab – The maps made this article for me: showing where Americans over 70 live (5% of the population in the county where I live now) and the death and birth in the use that categories whether population is naturally decreased on increasing by county (it naturally increasing where I live now).

Urban Plant Diversity – Cool Green Science – The theme of this article is to plant native species…less expensive, require less maintenance, and harbor greater diversity overall.

Social pursuits linked with increased life satisfaction -- ScienceDaily – This result seemed intuitive to me. As we get older and don’t have the level of social contacts we had during our career years, choosing activities that provide social interaction have to be done more consciously.

The State(s) Of Distributed Solar -- 2017 Update | CleanTechnica – Hopefully more states (utilities within the states) will jump on the bandwagon. There is quite an uptick since 2015 so the trend is in the right direction.

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.

How to Access Your Medical Records | Berkeley Wellness – I like the patient portal idea…just wish that every provider seems to have their own separate one.

First floating wind farm, built by offshore oil company, delivers electricity | Ars Technica – Hywind Scotland began producing power in September…now delivering to the Scottish grid. The turbines don’t require a firm attachment to the seafloor…using suction anchors like offshore drilling.

Germany Sees Drastic Decrease in Insects | The Scientist Magazine® - This story was reported in several my the feeds I monitor. A 27 years study….insect biomass declined by about 75% in that time. And the sampling was done in nature preseves!

Symmetrical Eyes Indicate Dyslexia | The Scientist Magazine® - Interesting….but what next.

The Millipede That Protects Itself with Cyanide – Cool Green Science – We found millipedes at the Belmont BioBlitz…but not these cyanides producing ones. Still – fascinating critters of the forest.

Stone Age Britons Feasted While Building Stonehenge | Smart News | Smithsonian – Pigs – maybe fattened with something sweet, like honey – that came from all over Great Britain. Cattle to a lesser extent.

The Real-Life Whale That Gave Moby Dick His Name | Smart News | Smithsonian – A little history behind the novel.

Compound Interest - Broccoli colour changes and cancer-fighting compounds – I tend to eat broccoli raw but have noticed the color change when it is cooked – never thought about why it did.

Top 25 Wild Bird Photographs of the Week #110 and  #109 – Birds and more birds…I can’t resist including them.

Prozac in ocean water a possible threat to sea life -- ScienceDaily – Medications can have unintended consequences far beyond out intent.

Reimaging Neuroscience’s Finest Works of Art – Recreating the work of Santiago Ramon y Cajal’s century old drawings of the nervous system

Top 25 Wild Bird Photographs of the Week #103 –  There is wood duck image near the end of this group….I have never managed a view from the front. This one has the reflection too.

Utilities Grapple with Rooftop Solar and the New Energy Landscape – I’m glad some utilities are adapting in a positive way to renewable energy. If they don’t – I think more people will be motivated to add battery capacity as the technology becomes available and be ‘off grid.’

New Guide: Smart, Sustainable Materials at Home – This is some I’ll take a look at more thoroughly if I am doing any renovations to an outdoor area.

Wind power costs could drop 50%. Solar PV could provide up to 50% of global power – Are solar and wind energy underestimated? They may be getting cheaper and scaling up faster than the most optimistic forecasts of a few years ago. Hurray!

The Smartphone’s Future: It’s All About the Camera – Some tech…just over the horizon but plausible based on what is available already.

Opinion: The Flood Reduction Benefits of Wetlands – There are lots of studies that will come out of the hurricanes that are impacting the US. This one was based on Hurricane Sandy and came out on August 31. It reported that insurance industry models show that during Hurricane Sandy, marshes prevented $625 million in direct flood damage in 12 states….a reduction in property damage by as much as 30% in some states.

Artificial warming trial reveals striking sea-floor changes – When researchers heated up a slice of Antarctic sea bed by 1 degree (Centigrade), changes were visually discernable: some species grew twice as fast in the heated conditions, different animal communities developed…one bryozoan became so dominate on the warmer sea floor that the diversity of species went down. The researchers already have more experiments planned.

Podcast Series Delves into History, Cultures of Mesa Verde – There are three episodes so far (available here) with a plan for additional ones in 2018.

Our Hurricane Risk Models are Dangerously Out of Date – More than half the area flooded by Harvey was ‘outside of any mapped flood zone’! It seems like insurance companies and property owners need a better understanding of risks…and the old models are no longer adequate.

Top 25 Wild Bird Photographs of the Week #101 and #102 – 50 bird pictures this week! My favorite in the first group is the barn owl (and the other owls in this group). My favorite in the second group are the two pictures of spotted owlets! --- I am drawn to owls this week for some reason.

Voyager: Inside the world’s greatest space mission – The two Voyager space craft were launched in 1977…and are both sending back messages to earth.

Trees with ‘crown shyness’ mysteriously avoid touching each other – I haven’t observed this phenomenon in our Maryland forests…but now when I am in a forest, I’ll always look for it!

Time Spent – Who Americans spend their time with (from Richard Watson’s blog). It changes with age. The last chart shows that as we get older we spend more and more time alone.

Air pollutions ranking in 32 cities –  LA ranks 24; Washington DC, San Francisco and New York are 26-28; Boston is 31. Delhi, Beijing, and Cairo are the top three.

Trees and shrubs offer new food crops to diversity the farm – Ongoing research from the University of Illinois trying to mimic the habitat features, carbon storage, and nutrient-holding capacities of a natural system with a farming method that incorporates berry and nut bearing shrubs/trees with alley cropping (hay or row crops)….to be economically and environmentally sound.

AWEA releases map of every wind farm and factory in America – There is a link to the interactive map. The red diamonds are manufactures and the blue dots are the wind farms themselves. It’s easy to see that manufactures happens a lot in areas other than where the wind farms are located….that the center of the country has a lot of installed wind turbines! We saw some of them in Iowa on our way to and from the solar eclipse last Monday.

Diversity Lacking in US Academia: Study – Under-representation of African Americans, Hispanics, and women in STEM faculties at public universities. There is a similar lack of diversity in PhD programs. On a positive note: the assistant professor is more diverse (more Asians, Hispanics and women) that the associate or full professor rank.  Unfortunately, this positive finding is not true for African Americans. Overall – still a challenge….and it impacts the broader labor market as well.

More than 300,000 Atlantic Salmon Spill into Pacific – Oh no! Hopefully this is not catastrophic in the long run. But – Why are they growing Atlantic salmon in pens in Puget Sound anyway?

Thanks to Co-op, Small Iowa Town Goes Big on Solar – Kalona, Iowa – not far from our route to the eclipse! It comes down to local self-reliance and economic development that made sense for this small town. Somehow a pointer to this article (from last February) was in a blog post I looked at when I returned home and I noticed where the town was…small world.
