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

Touching Image of Intergenerational Love Wins Black and White Minimalist Photography Prize – Minimalist…but powerful.

How an English castle became a stork magnet – 30 White Storks from a rescue project in Poland introduced in the rewilded habitat at Knepp Castle in southern England in 2016. At one point, storks even built nests on Knepp Castle itself although they usually build their nests in the crown of huge oak trees. The young storks started migrating in 2019. The colony has grown to about 80 storks…and is the first breeding colony in Britain in 600 years.

Evidence for Domesticated Chickens Dated to 400 B.C. - A study of eggshell fragments unearthed at 12 archaeological sites located along the Silk Road corridor in Central Asia.

Noisy Summer Ahead for U.S. as Dueling Broods of Cicadas Emerge - It is the first time these two broods are going to be emerging in the same year since Thomas Jefferson was in the White House. Mating season will last until July.

California’s Live Oaks in Focus - Some centuries old, the oaks are magnificent giants that can grow up to 100 feet tall and are what remains of a forest that once blanketed the region.

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Analyzing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health. Microparticles from car tires, pesticides from farmers' fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach.

Cars & Road Trips Made a Huge Difference in Women’s History – One of the first cars ever built got taken by a woman, without permission, on the world’s first road trip! Bertha Benz wanted her husband’s invention to be seen out in the country so people would buy it, but her husband Karl Benz was being timid about it. So, she took the car out on a road trip with her kids.

Common household chemicals pose new threat to brain health - The new study discovered that some common home chemicals specifically affect the brain's oligodendrocytes, a specialized cell type that generates the protective insulation around nerve cells. Loss of oligodendrocytes underlies multiple sclerosis and other neurological diseases. They identified chemicals that selectively damaged oligodendrocytes belong to two classes: organophosphate flame retardants and quaternary ammonium compounds.

The Soundtrack of Spring on the Platte River – Sandhill cranes staging last month along the Central Platte River in Nebraska. So many birds….lots of sound.

These Are the Most Polluted National Parks – Many national parks are suffering from air pollution and facing threats stemming from human-caused climate change. 98 percent of parks suffer from visible haze pollution, while 96 percent are grappling with ozone pollution that could be harmful to human health. Four of the nation’s parks with the unhealthiest air are in California: Sequoia and Kings Canyon National Park, Joshua Tree National Park, Mojave National Preserve and Yosemite National Park. Another California site, Death Valley National Park, also made the top ten list. 57 percent of national parks are facing at least one threat stemming from climate change that could permanently alter its ecosystems, with many parks grappling with multiple issues at the same time. Invasive species were the most prevalent issue.

The 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.

Federal flood maps are outdated because of climate change – The challenge of record rainfall events becoming more common and resulting in flooding of places not seen as vulnerable previously.

Hundreds of Monumental “Kites” Spotted in Arabian Desert – Low stone walls that could be enclosures used to guide game for capture/slaughter as early as 8000 BC.

The mystery of the human sacrifices buried in Europe's bogs – Sacrifices or maybe burial for anyone that died mysteriously or unnaturally. I remember being fascinated about the ‘bog bodies’ back in 1970s…buying the book about them by P.V. Glob.

Diet change may make biggest impact on reducing heart risk in people with hypertension – Too bad that the study also found “the availability and affordability of healthy food sources does not easily allow people to follow the DASH diet.” Diets are hard enough to sustain without those extra challenges.

Despite its innocently furry appearance, the puss caterpillar’s sting is brutal – The don’t look vicious….but the hairs have poisonous barbs! There are other caterpillars that also have ‘hairs’ and can deliver painful stings – like the saddleback caterpillars. In general…I avoid handling caterpillars with hairs or bristles!

Cancers in adults under 50 on the rise globally – Earlier detection could account for some of the increase…but it is unlikely to be the sole reason. 8 of the 14 cancers on the rise are related to the digestive system. With those types of cancers, the hypothesis is that the food we eat has changed dramatically and has changed our microbiome composition…and eventual these changes influence disease risk and outcomes. There is still a lot of work to be done but it appears that the drastic rise in early onset cancer began around 1990.

The biggest myths of the teenage brain – Hopefully some of these findings will be factors in decision making for things like high school hours and how to help teenagers better understand themselves.

NREL Study Identifies Opportunities & Challenges of Achieving the U.S. Transformational Goal of 100% Clean Electricity by 2035 – No single solution….having multiple pathways to the goal is probably a good thing.

Arctic lakes are vanishing a century earlier than predicted – Warmer temperatures and more abundant autumn rainfall have caused permafrost around/beneath Arctic lakes to melt…and the lakes shank between 2000 to 2021. The reduction in lakes impacts migratory birds and other wildlife…and human communities in the Arctic.

Fall Foliage Prediction Map – My road trips this fall will offer many opportunities to see fall foliage: 1st week in October in Michigan and Canada, the rest of October around Missouri, then Texas later in October into November.

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 human brains were bigger 3,000 years ago – Some possible explanation: human populations reached a large enough size to share/divide labor and knowledge with others, writing….however, brain size/IQ relationship is not deterministic.

Operating rooms are the climate change contributor no one’s talking about – The health care industry accounts for 8.5% of all greenhouse gas emissions in the US. Operating rooms represent 70% of waste in hospitals and 3 to 6 times as much carbon as the rest of health systems.

Where tornadoes strike most frequently is changing – More erratic tornado activity and the broad impacts of climate change.

Do you have a lost twin? - The rate of twins among live births is only about 1.3%. But as many as 12% of all naturally conceived pregnancies may begin as twin pregnancies.

Wild fox kills 25 flamingos and a duck at National Zoo – We see foxes in our neighborhood. They seem to have adapted to the suburban environment. This one was very efficient to kill 25 birds, though.

A 10,000-year history of geo-ecological change in Yellowstone’s lower geyser basin – A study using a 26.5-foot core from Goose Lake.

US could cut transport emissions by 34% b 2030 – The current trend will reduce emissions by 19% but a bit more focus would provide a bigger reduction.

Garbology: How to spot patterns in people's waste – We’ve been getting rid of a lot as we prepare to move. I try to do as much as possible via donations and recycling…but there is still a lot going in the trash. Some of it came from Texas with us back in 1983…and was still in the same box!

6,000-Year-Old Slate Rings May Have Symbolized Relationships – Friendship rings? Careful analysis revealed the rings had been intentionally broken…and shared (i.e. pieces of a ring were found in two separate burial sites).

How Taipei discovered an active volcano on its doorstep – Disconcerting. Even of there is some ability to provide early warning of an eruption…could the city be abandoned quickly enough?

Gleanings of the Week Ending April 16, 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.

Purple gallinule with chicks – I remember seeing an adult purple gallinule on a birding field trip in Florida. Aren’t the chicks cute? Little black fluffs.

Reproductive factors and dementia risk – Hurray! My life events skew toward reduced dementia risk…according to this study.

Macro photos reveal the often unseen beauty and diversity of slime molds – Hmmm…maybe I should hone my observational skills to find these on my next hike…attempt some macro photography of them.

As EV Sales Soar, Automakers Back Higher Fuel Standards – So glad that industry is finally onboard…projecting a ‘we can do it’ attitude. I’d rather society take action…build some optimism into our view about the future rather than being depressed by trends that seem dystopian.

Beginner’s Tips for Identifying Backyard Bird Nests – It’s the nesting time of year! Look…id…don’t disturb!

Ozone may be heating the plant more than we realize – We’ve been concerned about ozone in the upper atmosphere for years (hence the Montreal Protocol) but this study also points to ozone in the lower atmosphere (caused by chemical reactions between pollutants like vehicle exhaust fumes and other emissions) as contributing to climate change as well. Until now, we thought of lower atmosphere ozone as a health problem (I get headaches if I am outdoors on a high ozone day, for example). This research says that it also is contributing to climate change by affectioning ocean heat uptake.

American Lung Association Says EVs Save Lives – Good for our health….and also for the planet. I also noted that where I live now is in the American Lung Associations Tops 10 US urban areas at risk from airborne pollution…another reason to move away from this area!

New Technology Employed to Protect Pompeii – A four-legged robot used to gather data on structural and safety issues.

Flamingo that escaped from a zoo in Kansas is spotted once again in Texas 17 years later – The flamingo is a species from Tanzania….and must be a very lonely bird.

Brain charts for the human lifespan – Normative trajectories derived from over 100,000 MRI scans that allow quantification of individual variation. Figure 1 in the post can be enlarged by simply clicking on the image.

Gleanings of the Week Ending August 1, 2020

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.

Identifying sources of deadly air pollution in the United States -- ScienceDaily – Focusing on fine particulates associated with heart attacks, strokes, lung cancer, and other diseases…about half comes from burning fossil fuels; the other half is from animal agriculture, dust from construction and roads, and burning wood for heating/cooking. Ammonia is one pollutant that is not regulated as much as the others and yet it causes a 5th of all deaths caused by fine particulates. It could be reduced with targeted manure management and improving formulations of cleaning supplies, paints, and inks, etc.

Free Technology for Teachers: 500+ Icebreaker Questions – These could also be used as writing prompts…they are good for a bit of self-exploration…useful even if you are not in as many groups right now.

Aztec Palace and House Built by Hernán Cortés Unearthed in Mexico City | Smart News | Smithsonian Magazine – History through layers of stone floors.

Biosignatures may reveal a wealth of new data locked inside old fossils -- ScienceDaily – Not DNA…chemical analysis (using non-destructive Raman spectral analysis) of products of degraded proteins, lipids, and sugars in fossils. Results group into 3 types of biosignatures: biomineralization, tissue, and phylogenic.

Infographic: What Social Isolation Can Mean for the Brain | The Scientist Magazine® - I wondered if the brain structural observations were a cause or effect (or neither). Does the observation that people who are lonely have smaller amygdalae because that are isolated or because they were born that way and it wouldn’t matter if there were a lot of people interacting with them…they would always feel lonely/isolated.

Top 25 birds of the week: July 2020 - Wild Bird Revolution – Always beautiful birds.

Innovative Birds Face a Lower Risk of Extinction | The Scientist Magazine® - Birds that are dropping nuts on roads, stealing burning candles to eat the wick, using bread to lure fish, and pecking open sugar packets…..coming up with new behaviors to cope with new aspects of their environment.

A Silk Road Renaissance - Archaeology Magazine – Many more commodities than silk on the ‘silk’ road: jade, glass, spices, metalwork, ceramic….and missionaries. And the Sogdians were the people that made it work from the 5th to 8th centuries. Panjakent, in modern Tajikistan, has been excavated since the 1940s; many murals have been found depicting myths, fables and everyday life of the Sogdians. In 755 a failed Sogdian coup against the Chinese emperor and thereafter incursion of Arabs from their west caused the culture to fade.

New Research Reveals Surprising Origins of Egypt's Hyksos Dynasty | Smart News | Smithsonian Magazine – Based on chemical analysis of skeletons from the Hyksos capital, the dynasty was likely the result of an immigrant uprising rather than a hostile outside invasion!

Weird and Unbelievable Facts About Earwigs – Entomological trivia…always fun.

Unique Activities for Yesterday:

Blue Jay Behavior.  There was a blue jay on the deck railing making noise….fluttering its wings…making eye contact with 3 or 4 other blue jays around at the time. Those other jays seemed to ignore the ruckus and flew away. Then the bird flew down to the floor of the deck to look for seeds. Maybe it was a fledgling wanting to be fed by the adults…but the adults were forcing the young bird to find its own food? I’m not sure…but I enjoyed witnessing the minute or so of action…whatever it was about. Maybe it was the same jay that tried to get seed from our bird feeder a few days ago (and failed).

Gleanings, MAELSTROM prompt, and a Phoebe

Continuing the blog post series prompted by COVID-19….

Gleanings from the Past Week

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 world’s most nutritious foods - BBC Future – The one on the list that surprised me was ‘pork fat.’

New Thoughts on Corn Cultivation at Cahokia - Archaeology Magazine – Evidently maize arrived between AD 900 and 1000…about 1,000 years later than previously thought. I remember visiting Cahokia in 2010 about this time….a road trip from Ithaca NY to Flagstaff AZ with my daughter for her summer of undergraduate research.

Old Wisteria Tree in Japan Is the Most Beautiful in the World – I missed the wisteria blooming at Brookside Gardens this year. This 150 year old tree in this post is huge in comparison.

How the news changes the way we think and behave - BBC Future – I find that I feel better when I don’t check the news as often…once or twice a day is often enough unless there is something happening that impacts what I am doing (like very bad weather coming). I want to stay informed but don’t need stories repeated again and again…one time is generally enough and there are very few that I need to know as they are developing.

Top 25 birds of the week: #May 2020 - Wild Bird Revolution – A little feathery color….

Waves of Fluid Bathe the Sleeping Brain, Perhaps to Clear Waste | The Scientist Magazine®  - Still a lot to learn about the brain. I found myself wondering of poor sleep is the cause or effect of some disorders.

An Intimate Look at Italy’s Saffron Harvest - The New York Times – Color and flavor – and labor intensive.

Saber-tooth surprise: Fossils redraw picture of the fearsome big cat – The big cat was a forest/ambush hunter rather than one that hunted in more open environments.

Welcome Back! | The Prairie Ecologist – Noticing the firsts of spring….a bird returned…insects emerging (or sometimes returning), plants beginning to grow….lots to take in.

Medieval Arrows Inflicted Injuries That Mirror Damage Caused by Modern Bullets | Smart News | Smithsonian Magazine – The English longbow. The best ones were made from yew and measured 6 feet long. Drawing the weapon required 150-180 pounds of force. They shot arrows to 1,000 feet. At the Battle of Crecy in 1346, historians estimate that the English archers shot as many as 35,000 arrows per minute….were victorious even though they were outnumber by 2 to 1.

A Zentangle Prompt

Experiment with the MAELSTROM pattern. This is a grid pattern and is an opportunity to play with different orientations of a simple basic design made in each small square.  I always like to reuse materials I have around the house and an old calendar is great for these patterns. My calendar has large enough blocks for each day that I divide each into 4 x 4 grids and then cover the whole page (except for the small blocks that have a number in them) – in this case with MAELSTROM variations. I’ll share the results with you tomorrow.

img843.jpg

Here is a tile I made yesterday based on the prompt: Make a tile with TRIPOLI as the central tangle.

Unique activities for yesterday:

Phoebe in the morning. I hear a phoebe almost every morning but usually don’t get a photograph. Yesterday I did…while it was proclaiming its name.

IMG_9976.jpg

Small chipping sparrow. I’ve noticed a chipping sparrow that looks smaller than the others coming to the feeder the past couple of days. I finally got a picture of it with another chipper on the other side of the feeder. Doesn’t the one on the right look smaller? Maybe it is just the way the bird is oriented/holding itself.

Top 25 Wild Bird Photographs of the Week: November – Enjoy the birds!

Common nutrient supplementation may hold the answers to combating Alzheimer's disease -- ScienceDaily – Choline….not sure I am even getting the recommended intake very often. Taking a supplement might be worthwhile.

Female scientists gaining recognition for their breakthroughs – A little history….and hope that things are changing for female scientists working now. This article is from the November 2019 special issue of National Geographic, “Women: A Century of Change.”

New report highlights Alaska’s last five years of dramatic climate change | NOAA Climate.gov – There are often stories about dramatic high temperatures in Alaska…but this is an overall look at what is happening.

A Field Guide to Commonly Misidentified Snakes – Cool Green Science – The first photograph is labeled ‘#NotACopperhead’ – lots of snakes have probably been killed by people thinking they were a poisonous snake.

Image of the Day: Stick and Leaf Insects | The Scientist Magazine® - The article includes a link to the full study too (here). The figures alone are worth a look.

Non-pharmacologic treatments may be more effective for psychiatric symptoms of dementia -- ScienceDaily – Outdoor activities, massage and touch therapy may be more effective that drugs….and they don’t have the side effects of the drugs. I hope the findings of this study are incorporated into care decisions.

Image of the Day: Brains and Braincases | The Scientist Magazine® - The human skull shows adaptations for walking upright more than changes because of our brain structure.

Photos of the Week – October 18, 2019 | The Prairie Ecologist – Milkweed seeds.

Textile technology: Joseph-Marie Jacquard and the loom that changed the world – Some textile history from the early 1800s.

Gleanings of the Week Ending November 9, 2019

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.

Infographic: How Air Pollution Could Affect the Brain | The Scientist Magazine® - A quick and disturbing summary. The evidence of harm: particles like those produced by vehicle engines found in frontal cortex (postmortem), reduced volumes of white matter, slowed development of children, inflammation related damage to brain cells, and higher accumulation of Alzheimer-associated proteins.

Happier Babies Have an Edge - Scientific American Blog Network – The more children experience happy emotions, the more time they spend building skills and relationships that help them in the future.

900 Pythons Removed from South Florida – That’s a lot of snakes. Kudos to the Python Action Team. There are other organizations (government and non-profits) working on this too. I wish the article would have included information about what they do with the snakes after they are captured. Presumable they are killed.

Study: 95 percent of baby food contains traces of toxic metals - UPI.com – Not good. The full report referred to in the article is available here. I wonder if pediatricians are changing their recommendation when it comes to some foods (like rice cereal for babies).

Newly discovered virus infects bald eagles across America -- ScienceDaily – Over 1/3 of America’s Bald Eagles are infected…and it might be causing a fatal disease – Wisconsin River Eagle Syndrome.

BBC - Future - What life might be like in alien oceans – Lots of possibilities. It will be interesting to get some probes (submersibles, etc.) out to the moons of other planets in our solar system that have alien oceans…maybe life.

From quills to typewriters: how the industrial revolution changed our writing culture | Europeana Blog – A little history lesson.

National Science Board highlights Skilled Technical Workforce shortage in new report - The Bridge: Connecting Science and Policy - AGU Blogosphere – “Without immediate action, the US risks falling behind other nations that are making significant investments in their Science and Engineering workforce and the Science and Technology enterprise.”  The whole report can be found here.

The Platypus Is Weirder Than You Ever Imagined – Cool Green Science – They don’t have a stomach, their venom can help treat diabetes, their milk can help fight antibiotic resistance….the list goes on.

Photography in The National Parks: Your Armchair Photography Guide To Olympic National Park, Part 2 – The Forests – National Parks….always a great destination for nature photography.

Gleanings of the Week Ending October 26, 2019

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.

Scientists Find Way to Fully Recycle Plastics Without Losing Quality - Yale E360 – I hope this process undercuts plastic manufacturing from fossil fuels…plastics should not be the glide path for the oil companies! The heating of the plastic to 850 degrees for this process should be done with renewable energy. And what happens to the parts that don’t get recycled (I assume there is waste from the things that weren’t plastic that got into the stream (i.e. ‘dirty’ containers).

Top 25 Wild Bird Photographs of the Week: Bird Interactions – National Geographic Society Newsroom – Birds with other birds (not always the same species).

Maya Tomb of the Unknown Red Queen - Red from cinnabar (mercuric sulfide) power that covered everything inside the limestone sarcophagus…a mask of malachite.

Time Spent in Nature Is Good for You | The Scientist Magazine® - Spending at least 2 hours in nature per week is strongly correlated with self-reports of being in good health and having high well-being…..based on a study in the UK with 20,000 participants between 2014 and 2016. Intuitively – the idea seems right. But what does ‘time spent in nature’ really mean and what is it that causes the correlation? Do you have to be outdoors or is viewing it enough? I am outdoors in beautiful natural places (gardens, forests, seashores, rivers and lakes) so frequently…the 2 hours per week is at the low end for me…except for the coldest or wettest weeks.

Cooking food alters the microbiome: Raw vs. cooked diets have distinct effects on both mouse and human gut microbes -- ScienceDaily – No recommendations from this research but lots of prompts for further research.

The Short List Of Climate Actions That Will Work | CleanTechnica – These are country or continent type actions like: electrify everything, overbuild renewable generation, build continent-scale electrical grids and marks, fix concrete, change agricultural practices, shut down coal and gas generation aggressively. Some of them can be impacted by individual decisions…to move in the direction. For example – 1) The CSA I belong is on a path to not use plastic to control weeds and retain moisture around their crops. 2) The next house I buy (in the next 2-3 years) will be all electric and have solar panels…maybe battery storage too….maybe geothermal heating/cooling. 3) The next car I buy will be an EV rather than a plug-in hybrid like I have now. And I can change my yard into a mini-forest (of redbuds, dogwoods, spice bush, hollies….not huge trees but ones that are native to the area where I live).

Air Pollution May Damage People's Brains | The Scientist Magazine® - Mortality, respiratory health, cognition, and social behavior. This is scary. This is yet another reason to move away from fossil fuels.

Humankind did not live with a high-carbon dioxide atmosphere until 1965 -- ScienceDaily – I was in 5th grade in 1965. It was the grade between two memorable events: seeing a tornado just before it touched the ground and traveling with my parents to Mexico City for a weeklong vacation (two firsts: on an airplane…and out of the US). But the cross over to a high-carbon dioxide atmosphere has the greater long-term impact. I already suspect that unless something changes dramatically, climate change by midcentury will probably shorten my life.

Ailing U.S. pecan industry calls on India to reduce tariffs - UPI.com – I couldn’t find an update on this story from a few weeks ago. Evidently China used to buy 40% of the pecan crop in the US but now there is a tariff and the market is gone. So, the farmers are trying to develop the Indian market. It’s been tough to be a farmer for many years…but the tariffs have added even greater challenges.

Stressed out: Americans making themselves sick over politics: One in five report lost sleep, damaged friendships -- ScienceDaily – If individuals are stressed by politics….hopefully they’ll realize that it’s time to implement strategies to reduce the stress. Spending less time on ‘news’ would provide time to shift focus to other aspects of life – skew toward activities that make you happy and help others too. ‘Staying informed’ of politics 24/7 should not be a priority (although participating in elections should be).

Gleanings of the Week Ending June 14, 2019

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.

Antibiotics found in some of the world's rivers exceed 'safe' levels, global study finds -- ScienceDaily and Hundreds of world's rivers contain dangerous levels of antibiotics – Same story from different news feeds. Antibiotics we take are not broken down in our bodies and are excreted. Wastewater treatment does not take them out of the water so the rivers are – over time – building up more antibiotics.

Ancient Fingerprints Show Men and Women Both Made Pottery in the American Southwest | Smart News | Smithsonian – The breadth of men’s finger print ridges are 9% wider than those of women…so pots that are made via pinching layers of coiled clay together using the thumb and forefinger (leaving fingerprints) can be analyzed to determine the gender of the person that made them. It turns out at Chaco Canyon that men and women made pottery…unlike the more modern tradition of the skill passing from grandmothers to mothers to younger women.

Route 66 Considered for National Historic Trail in The Park System – On a recent road trip, the Pacific, MO hotel we stayed in (west of St. Louis) was near Route 66. They had a map to continue the journey through Missouri on stretches of the old road. We needed to reach our destination quickly so stayed on I-44…but maybe sometime when we can take our time…we’ll take Route 66 where we can.

CITY SPROUTS: The Budding Movement to Integrate Garden-Based Learning in Public School Education | Children & Nature Network – A laudable goal…but it takes work. With teachers that already have a lot to do….organizing garden-based learning might be a tough addition to their job jar.

Most of the World’s Macadamias May Have Originated from a Single Australian Tree | Smart News | Smithsonian – The majority of macadamias are grown in Hawaii…so the lack of diversity within the trees in Hawaii leaves the crop open to species-level risk. This article talks about the research and search for wild plants in Australia to increase the diversity within the macadamia gene pool.

Seven US Species Invading Other Countries – Cool Green Science – We talk a lot about non-native species invading the US. Here are some that have gone the other way.

A Sea of Sagebrush Disappears, Making Way for Fire-Prone Cheatgrass: NPR – Nearly 75% of the acres burned by wildfires in the west are range lands rather the forest. And what burns is sage and cheatgrass. The problem is that cheatgrass, an invasive grass, grows faster than sage and is taking over land where sage once dominated…and cheatgrass is more flammable. Put that together with climate change and the look of the west is changing.

Megacities Like Paris and London Can Produce Their Own Clouds | Smart News | Smithsonian – The urban heat island phenomenon has been known for a long time. Now studies are looking at cloud cover over cities and it appears they are 10% cloudier than rural areas.

Still snarling after 40,000 years, a giant Pleistocene wolf discovered in Yakutia – Found in Siberia. The discovery was announced as the opening of a Woolly Mammoth exhibition in Tokyo organized by Yakutian and Japanese scientists. The same team also presented a well-preserved cave lion cub.

Six fingers per hand – People with 6 fingers on a hand (a form of polydactyly) can perform movements with one hand where people with 5 fingers would require 2 hands. The brain of polydactyly subjects controls the additional degrees of freedom the additional finger provides without sacrificing any other brain functions.

I have a growing list of gleanings from sites that are not operational because of the partial government shutdown; they’ll come out in the list for the Saturday after the sites are operational again.

Climate, life and the movement of continents: New connections -- ScienceDaily – Sediment, which often includes pieces of dead organisms, may create a lubricating effect between plates, accelerating subduction and increasing plate velocity!

BBC - Future - Six reasons your memory is stranger than you think – Timelines are hard (many times inaccurate) from memory…I’m glad I keep a running list of important family travel and events.

Regenerative Cities: An Urban Concept Whose Time Has Come! | CleanTechnica – Re-thinking what cities of the future could be.

Scientists call for eight steps to increase soil carbon for climate action and food security: International coordination and financing essential -- ScienceDaily – Big benefits…but hard to come by the collective push to obtain them.

Earthquake Damage Detected in Machu Picchu - Archaeology Magazine – Evidence of an AD 1450 earthquake that damaged Machu Picchu is seen in cracks and stone damage of the buildings. The Inca’s modified their construction techniques after the event too.

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.

Ring in the New Year With Dazzling Total Lunar Eclipse of a Supermoon | Smart News | Smithsonian – Hope we have good weather on January 20-21….since it should be visible from our house!

Drug pollution concentrates in stream bugs, passes to predators in water and on land: Animals that eat insects in or near streams at risk of being dosed with pharmaceuticals -- ScienceDaily – Wow – the existence of macroinvertebrates in our local rivers is an indicator of water quality (the focus of the field trips with high schooler’s I’ve been doing in recent years) but those same macroinvertebrates are probably getting a healthy dose of pharmaceuticals from the water…the fish that eat them act as concentrators….and some of those fish are eaten by people.  I hope reserarchers in the US are doing similar studies to the one described in this article.

Premature Birth Report Cards | March of Dimes – Only one state gets an ‘A’ – and many areas of the country are getting worse when it comes to premature births.

High levels of previously unsuspected pollutant uncovered in homes, environment -- ScienceDaily – An organophosphate that is known to be toxic was a surprise find in household dust…more study needed on its impact on humans that live with it at that level. The chemical is used as a flame retardant or plasticizer in consumer products…and may also form as other chemicals degrade.

Wildlife Populations Have Shrunk by 60 Percent Since 1970 | The Scientist Magazine® - The impact of less and less space for habitat for any species other than those directly related to humans.

Historic Low Sea Ice in the Bering Sea: Image of the Day – Big changes to the amount of ice.

Algae Blooms in Lakes & Oceans Creating Pollution That Harms People, Pets, & The Planet | CleanTechnica – Who want to do anything in green water. Ugh! Another reason to slow the flow and reduce the extra nutrients that we send into our rivers, streams and lakes (that cause algae blooms).

World’s Largest Victorian Glasshouse Opens Doors After Five-Year Restoration Project | Smart News | Smithsonian – It’s easier to the structure of the building at this point…before the many new plants get very large and block the view. The building was originally opened in 1863…and this was it first restoration.

Alligators on the beach? Killer whales in rivers? Get used to it: Large predators once hunted to near-extinction are showing up in unexpected places -- ScienceDaily – Rebounding populations! They are returning to hunting grounds where they were common before hunting caused their near extinction.

Five Tips to Help Frogs and Toads in Your Yard: The National Wildlife Federation – Good recommendations for frogs…and wild life in general. I may repurpose my daughters old ‘turtle sandbox’ into a vernal pool (but will have to monitor it for mosquito larvae)

Why Teenagers Should Understand Their Own Brains (And Why Their Teachers Should Too!): NPR Ed: NPR – After being around middle school students this week…this article caught my interest. I’m glad we are learning more about the teenage brain and can come up with solutions to the problems caused to their sleep pattern by early school start times.

How Seeds from War-Torn Syria Could Help Save American Wheat - Yale E360 – From a seed bank near Aleppo…saving the seeds from the bank by taking them into Aleppo to Lebanon and now Kansas State and North Dakota State Universities developing wheat that is resistant to Hessian fly which has been an increasing problem with climate change (higher temperatures enough that the flies were not killed by the cold of winter, less water) significant enough that US grain yields were falling. Hurray for a diverse seed stock (and the US should take note to develop diversity rather than destroying via monoculture agriculture).

For how long will the USA remain the Nobel Prize leader? Empirical study on historical development allows a prognosis -- ScienceDaily – The graph is not positive for the US. It looks like the UK is recovering from a trough that developed in the 1990s while the US peaked in the 1980s and has been going down since then (the metric being Nobel prizes per year per 100 million inhabitants).

Top 25: Wild Birds on the Edge – National Geographic Blog – Endangered birds….many factors causing stressing these birds…no quick fix.

Explore Thurston Lava Tube At Hawai'i Volcanoes National Park By Flashlight  and The Nature Conservancy Transfers 222 Acres To Hawai'i Volcanoes National Park  - Reminded how much I enjoyed our trip to the big Island (and the national park there) a few years ago.

11 Chocolate Desserts That Are Totally Healthy – Dark chocolate…it’s wonderful that it is also good for you too – in moderation.

Long-term economic impact of cover crops: 29-year study finds cover crops offer benefits with no-till cotton systems -- ScienceDaily – Decreasing soil erosion….always a good thing.

Artists envisioned the future of work, and the results are pure fantasy - MIT Technology Review – What do you think? Some of these are (somewhat) logical extensions of existing technology and jobs.

Why Are You Seeing Robins in Winter? – Cool Green Science – I didn’t see any robins at my birdbath this winter, but we don’t have trees with berries that might be food for them. I did see some robins at Mt. Pleasant yesterday…a small group…and wondered if the warm weather we had earlier in the week (in the 70s) is bringing them in larger numbers to our area.

Saving a Crown Jewel – National Geographic – We spent some time at Santa Ana National Wildlife Refuge last November when we were at the Rio Grand Valley Birding Festival See my post here). The short video is worth watching. The wall that is being built through the refuge (destroying the refuge) is the proof of concept for the wall that some in our country want to build. It’s very sad.

BBC - Future - An effortless way to improve your memory – After reading this, I wondered if creating a Zentangle tile has the effect of a short rest period for me. I’ve noticed that it is easier for me to learn new material if I include breaks to make tiles!

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.
