Filling a Day of Social Distancing - 5/1/2020 - Gleanings

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

Here are the unique activities for yesterday:

Downloading Woody Plants of the Northern Forest by Jerry Jenkins.  The Northern Forest Atlas organization has 3 digital atlas guides: woody plants, mosses and sedges. They are available as free downloads (PDFs). The images are wonderful…the downside is that the guides are HUGE because of the high quality images. The woody plant guide is 630 MB. Put the download in a place you will remember to retain it as a reference (and avoid downloading it again).

Browsing the books illustrated by Frederick Richardson on Internet Archive. He illustrated books in the early 1900s. The samples below are from Edith Ogden Harrison’s The Enchanted House and Other Fairy Stories.

Walking laps. It’s been very wet here, so I’ve been indoors more. I’ve plotted various circuit paths through my house to get some exercise! I do laps for 5 or so minutes every hour…or that is the general goal.

Receiving a new office chair. My constant bouncing on the Swopper stool at my computer had recently started to bother my back rather than sustaining my back muscles….so I opted to move to a more traditional office chair. We had one that was over 30 years old that I thought might work but the height adjustment no longer functioned. My husband found a new chair from Staples…ordered it…and it came to our front porch within a day or so. It’s now assembled and will be the chair at my computer. The Swopper will still get used daily….but not as heavily as it has for the past 10 years!

And now for the weekly gleaning list….

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.

Deep Sea Squid Communicate with Glowing Skin: NPR – The video is a little over a minute…deep sea footage of Humboldt Squid taken by the Monterey Bay Aquarium Institute off the California coast.

To Cut Carbon Emissions, a Movement Grows to ‘Electrify Everything’ - Yale E360 – All-electric new construction…preparing the way for dramatic reduction of fossil fuel consumption.

Top 25 birds of the week: April 2020 - Wild Bird Revolution and Top 25 birds of the week: Blue Feathers - Wild Bird Revolution – A double dose of bird photographs this week!

Enjoy the Red-Winged Blackbird Show – I saw red-winging blackbirds on one of my walks in the neighborhood – at the storm water retention pond. There was a bit of drama I’ll share in a post next week.

The Hidden History in My Backyard – A history of a Florida backyard/neighborhood. I am content with the idea that my back yard was a forest….and that there is still a swath of forest down to the river.

Skulls from the Yucatan Peninsula a Clue to Early American Settlers | The Scientist Magazine® - Analysis of Quintana Roo skulls from people that lived 13,000-8,000 years ago…found in underwater caves that were above sea level at that time.

Pictures of Redwood National and State Park – Huge trees – always awesome.

Southwest Drought Rivals Those of Centuries Ago, Thanks to Climate Change - The New York Times – The last sentence is the bottom line: ‘We don’t have the whole story on Southwestern hydroclimate nailed down.’ The article talks about the analysis we have now….it probably means that the population growth in the Southwest happened at a time that was unusually wet, and that it won’t be supportable into the future.

Insect wings hold antimicrobial clues for improved medical implants -- ScienceDaily – Beginning to understand how nanopillar structures in cicada and dragonfly weeks kill bacteria on contact.

What chemical analyzes of human bones tell us about kitchen utensils in the Middle Ages - HeritageDaily - Archaeology News – Copper in bones….shows continuous exposure for cooper from AD 800 to AD 1800…consumed in daily diet prepared in copper cookware!

Filling a Day of Social Distance – 4/24/2020 - Gleanings

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

Here are the unique activities for yesterday:

Finishing Fashion as Design Coursera course. The theme for the last module was Expression. It was a good way to end the course. I have enjoyed both courses I’ve done from MoMA and will probably start a third one – What is Contemporary Art – early next week.

Hearing a piano practice. My husband opted to start up piano practice…not sure why he hadn’t thought to play it weeks ago. What’s not to like about a grand piano? It was tuned last winter just before the coronavirus pandemic, so it is in excellent condition. His playing didn’t last for long, because the cat demanded attention…and has decided that the best place to sleep is under the piano.

And then there are the gleanings for 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.

How Rain Evolved Its Distinct Scent—and Why Animals and Humans Love It | Smart News | Smithsonian Magazine – The chemical that is the scent of newly moistened soil, geosmin, has been known to scientists since the 1960s….but now we are figuring out its purpose. It is made by 120 of 122 species of bacteria in the genus Streptomyces that have been studied. The scent attracts springtails (tiny arthropods) that eat the bacteria and spread the bacteria’s spores via their excrement or the spores that attach to their body and then fall off. Many other insects, fungi and nematodes are killed by chemicals produced by the bacteria. So – the scent after rain is connected to the lifecycle of bacteria that are one of the most important sources of antibiotics known to science!

Top 25 birds of the week: Terrestrial Birds - Wild Bird Revolution – Enjoying images of birds from around the world.

Long-living tropical trees play outsized role in carbon storage -- ScienceDaily – They used ‘hindcasting’ to validate their model: seeded the model with forest composition data collected at their site in Panama during the 1980s and then ran the model forward to see that it adequately represents the changes that occurred from then until now.  Once that was done…they can use the model to predict what will happen to the forest with climate change. Will the forest continue absorbing some of the excess carbon – or not?

Flamingos in Captivity Pick Favorite Friends Among the Flock | Smart News | Smithsonian Magazine – 2-4 birds…not limited to mated pairs. Some were together for the whole 5 years of the study! The study found no loners but some bounded between groups.

What do soap bubbles and butterflies have in common? Butterfly breeding gives insight into evolution of iridescence -- ScienceDaily – A 75% increase thickness in the chitin lamina of wing scales turned iridescent gold to shiny blue….the same way a soap bubble iridescence works! And now there is a whole new genetic approach to investigate structural color in butterflies – and may lead to new ways to produce photonic nanostructures for solar panels, paints, clothing, and cosmetics.

How to mine precious metals in your home - BBC Future – Theoretically - the “urban mine” is far richer in high value materials per ton than traditional metal ore mines….but we don’t quite have the way to collect the ‘ore’ or effectively extract the metals.  

Springfield Plateau: Cowbird Eggs – Cowbirds….I’m trying not to be too judgmental. (I’ve included a picture of cowbirds at our bird feeder below. The female is a more frequent visitor than the male.)

2020 04 IMG_8702.jpg

Colorful Image Lights Up Microscopic Guts of 'Water Bear' | Smart News | Smithsonian Magazine – Enhancing our view of a tardigrade with fluorescent stain….and done close to where I live at University of Maryland Baltimore County!

Take a Free Virtual Tour of Five Egyptian Heritage Sites | Smart News | Smithsonian Magazine – These are best viewed on your largest monitor!

Common protein in skin can 'turn on' allergic itch -- ScienceDaily – Turning off the production of the protein periostin in the skin can reduce the itch from atopic dermatitis (in mice). More research needed to see if it works for humans too.

Filling a Day of Social Distance – 4/17/2020 - Gleanings

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

Here are the unique activities for yesterday:

Browsing through some issues of Vogue. The Internet Archive has some issues of Vogue online. I particularly enjoyed the one labeled Vol 138: Vogue which includes issues from October - December 1961 (a bound reference volume); you’ll have to create a free-sign on to check it out – browse through. I was in 2nd grade when these issues were originally published and the designs appealing; maybe we all have a subconscious affinity for clothes that were worn as we were growing up. It was a time when natural fiber fabrics were being replaced with synthetic fibers. I can remember learning to iron my cotton shorts and tops during the summertime when I was in the later grades of elementary school!

Noticing filaments algae in the sycamore branch vase. How did it get here? Were there spores on the branch when I brought it in? The picture on the left below is looking down into the vase, the branch being the diagonal shape in the lower left corner. I pulled some algae out and put it on the top of my iPad (using the iPad as a light table) and took a picture through the jeweler’s loupe (picture on the right)…not enough magnification to see any internal detail, unfortunately.

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.

These Colored Micrographs Show the Incredible Intricacies of Plants – A different botanical perspective.

Can fashion ever be sustainable? - BBC Future – This article fit right in with the Fashion as Design Coursera course I am working my way through right now. I already buy more than half my wardrobe from thrift stores and don’t buy very often. My closet is still too full; one indication is recently finding a pair of jeans I had forgotten about! This article has prompted me to think about how often I wash my clothes. Maybe I don’t need to launder some of them as frequently.

Why This Rare, Huge Ozone Hole Over the Arctic Is Troubling Scientists | Smart News | Smithsonian Magazine – It probably will close soon – but it’s an interesting phenomenon that probably would have gotten more press if coronavirus wasn’t overwhelming all other news.

Blood test detects over 50 types of cancer, some before symptoms appear -- ScienceDaily – This type of test has been a goal for years. Are we getting closer to reality?

Covid-19: The history of pandemics - BBC Future – The impact of coronavirus on our day to day lives is a unique experience for most of the world’s population. This article is a short history of  other pandemics: Justinian plague (6th century…killed as many as 50 million which was half the global population), the Black Death (14th century…killed up to 200 million), smallpox killed as many as 300 million people in the 20th century alone even though there was an effective vaccine available since 1796, 1918 influenza (50-100 million died), and HIV (killed 32 million and infected 75 million with more added every day). Since 1980, the number of outbreaks of new infectious diseases per year has tripled.

19 Incredible Winning Photos from Nature Photography Contest – Lots of interesting nature photos.

Wearable device lets patients with type 2 diabetes safely use affordable insulin option -- ScienceDaily – Maybe technology can deliver less expensive drugs in news ways….making the drugs more effective.

Bioprospecting for Industrial Enzymes and Drug Compounds in an Ancient Submarine Forest: NOAA Office of Ocean Exploration and Research: NOAA Office of Ocean Exploration and Research - An unusually large, biodiverse, and temporally stable wood-associated marine habitat off the coast of Alabama. Within 100-200 prepared culture plates, the team identified approximately 100 strains of bacteria, many of which are novel and 12 of which are already undergoing DNA sequencing for further study of their identity and their biosynthetic potential to make new drugs.

Photographer Immortalizes the Ice Waves of Picturesque Lake in Colorado – It must have been cold work capturing these images!

6 Creative Ways Wildlife Find Shelter • The National Wildlife Federation - A fun article…with some great photographs too.

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

Here are the unique activities for yesterday:

2020 04 IMG_8728.jpg

Photographing the sunrise. I seem to get busy and miss the sunrise most mornings…but not yesterday!

Catching up on Charles Cockell’s Life in the Universe Pandemic Series:

Noticing more sycamore leaves emerging. There are now three buds that have popped…lots of tiny leaves.

Making experimental face masks from materials I have at home….for when/if we need to go out. I made a mask with a paper napkin, small binder clips, the cut off top of a small gift bag (for the loops). The napkin would be replaced after each use…the rest sprayed with Lysol. It would probably fit better over the nose if I made some pleats. Even better using a scarf (or paper towels) and two hair ties/covered bands. (How to videos I watched). This is all about protecting others; I don’t want anyone to get sick if I happen to be an asymptomatic carrier.

20200403_114554.jpg

Started Fashion as Design course on Coursera. The week 1 optional 2-hour video of 4 speakers and then Q&A (Under Review and then Reading) on the topic was well worth it.

Links to my previous “filling a day of social distance” posts  here.

And now for the normal weekly gleanings post….

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. 

25 Photos of Madeira's Dreamy Fanal Forest by Albert Dros – Calming nature. It is a quite different forest than the one I see from my office window. Both views are much appreciated.

Tips for how to stay happy in troubling times - BBC Future – Hopefully, some of these work for you. I find that limiting the time I spend catching up on ‘news’ is the one I need to keep reminding myself about; it’s so easy to get absorbed in all the pandemic news (none of it good). I want to be informed but not 24/7.

Monarchs Covered 53 Percent Less Area in Mexico this Winter | The Scientist Magazine® - The last paragraph of the article was the worst news: “The butterflies have already begun their journey north but there is not enough milkweed in Texas to support the butterflies’ reproductive cycle this spring.”

How your personality changes as you age - BBC Future – It seems like there are a lot of positive general trends in personality as we age: more altruistic and trusting individuals, willpower increases, a better sense of humor, more control over emotions. They’re calling it ‘personality maturation’ and it continues until at least the 8th decade of life! And its observed across all human cultures.

Top 25 birds of the week: Eagles - Wild Bird Revolution – Never can resist the birds….

On This Scorching-Hot Exoplanet, a Forecast of Molten Iron Rain | Smart News | Smithsonian Magazine – 640 light-years outside our solar system

Tour A National Park from The Comfort of Your Couch -  Hmmm….I’m going to start working my way through the virtual tours….Maybe one a day?

Unprecedented preservation of fossil feces from the La Brea Tar Pits: A 50,000-year-old Snapshot of Los Angeles trapped in asphalt -- ScienceDaily – The La Brea Tar Pits have been studied for more than a century….but apparently there are still things to learn from them. Fossilized rodent pellets found in context (so definitely not modern, they also were radiocarbon dated to ~50,000 years ago). They are preserved along with twigs, leaves and seeds….an intact woodrat nest!

Massive Mammoth-Bone Structure Found in Kostenki, Russia - Archaeology Magazine – A circular structure about 41 feet in diameter…made with bones from at least 60 mammoths.

Tree Tapping Isn’t Just for Maples – The 2020 season is over for getting sap from trees – this is still an interesting article about how it is done…and other trees that also have sweet sap. I was surprised to see sycamore on the list.

Gleanings of the Week Ending March 28, 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.  

Tree Rings, Wildfires, and Climate | The Scientist Magazine® - Evidently the linkage between winter precipitation and fires in the spring in California – long documented in tree ring studies – has disappeared. Wildfires now are as likely to happen after a wet winter as they are after a dry one.

New Research Shows Healthy Agriculture Means Healthier Birds – Honing our understanding of healthy agricultural schemes that promote healthy farmland birds.

How cutting your food waste can help the climate - BBC Future – Over the past few years, I have started composting and reduced my food waste by eating food – never forgetting what I have in the refrigerator. Keeping a mental inventory of fresh fruits and veggies…freezing anything that I might not use before it goes bad….has been key. I enjoy frozen bananas in smoothies more than the unfrozen! This time at home (social distancing) gives me an opportunity for another round of reducing food waste….although it’s harder now since I’ve done all the easy actions.

'Grand Challenge' review stresses global impact of microplastics -- ScienceDaily  - Where major research and discovery are needed re microplastics impact on the environment and health. Recognizing that all plastic is not the same and new tools will be needed.

20+ Photos of a Snow-Covered Winter Wonderland in the Forest and 15 Incredible Finalists of the Smithsonian Magazine Photo Contest – So many beautiful pictures. I needed the boost of natural images this week.

Dragonflies are efficient predators: They consume hundreds of thousands of insects in a small area -- ScienceDaily – Exploring predation in the insect world…its impact on prey species and the community.

A Naturalist’s Guide to the South African Cape – Some unique species.

Top 25 birds of the week: Migratory birds - Wild Bird Revolution – I always enjoy the 25 bird pictures each week.

Sinking ships to stop erosion - The Landslide Blog - AGU Blogosphere – The example shows ships sunk after World War I to stop erosion…and now more than 100 years later – it’s obvious that it worked!

Staying in? Keep learning with science activities that kids and families can do at home | National Oceanic and Atmospheric Administration – Some resources from NOAA….ocean and atmosphere topics to explore without leaving the house!

Gleanings of the Week Ending March 21, 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.  

Can Destroying Senescent Cells Treat Age-Related Disease? | The Scientist Magazine® - Lots of trials going on…this may be a way to extended years of healthy life (not elongate life).

This 'Blood-Red' Snow Is Taking Over Parts of Antarctica | Smart News | Smithsonian Magazine – I remember seeing snow that was the color of watermelon in Colorado…it’s algae Chlamydomonas nivalis, which is the most common type of snow algae around the world. It hasn’t been as common in Antarctica until this year.

Spotted Zebras, Yellow Cardinals, and Three-Antlered Deer: What Causes these Animal Oddities? • The National Wildlife Federation Blog – Some uncommon forms of animals we all recognize.

What Makes a Venus Flytrap Snap | The Scientist Magazine® - It’s complicated…and nuanced so that the plant only invests in digestion efforts when there is food!

Just a Tiny Fraction of America’s Plastic Can Actually Be Recycled, Report Finds - Yale E360 – We can’t send it to China any more…so it’s all on us to clean up our own mess. Unless and until we can get recycling working well…it’s important for all of us to reduce our use of plastics as much as possible. It’s hard to do.

States with highest rates of melanoma due to ultraviolet radiation identified: Several landlocked states among those with highest rates -- ScienceDaily – It’s not all about being out in the sun either. The prevalence was higher in younger females due to tanning bed usage by teen girls in the late 1990s contributing.

Interactive Infographic: How Salt Transforms Coastal Forests | The Scientist Magazine® - We noticed this process as we’ve visited Blackwater National Wildlife Refuge over the years. There are some areas that used to be marsh with some trees that are now open water.

Top 25 birds of the week: March 2020 - Wild Bird Revolution – No birding festivals in our future near term….but still enjoying pictures taken by others.

Why your internet habits are not as clean as you think - BBC Future – A good compilation of studies about energy consumption for various aspects of our online activities….maybe we can skew toward the lower energy use ones more frequently. Some of the energy, we pay for in terms of our electricity use….others are embedded in products or services we use where the energy usage is not something we see directly.

Coronavirus: How hand sanitizers protect against infections – Compound Interest – Some timely chemistry.

Gleanings of the Week Ending March 14, 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.  

Shrikes: Meet the Bird That Impales Prey on Spikes – The bird creates its “pantry” on barbed wire…other spikey objects. Gruesome…but it’s an adaptation that works for the bird.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

Researchers Find Cell-Free Mitochondria Floating in Human Blood | The Scientist Magazine® - Surprise! Now to figure out their function….

Gleanings of the Week Ending March 7, 2020

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

Can we heat buildings without burning fossil fuels? - BBC Future – Capturing heat from nearby places…using it for heating. It’s geothermal in the cities!

Bloom in McMurdo Sound – Green swirls in the water off Antarctica (some of the green color might be on the ice as well.

Camera Trap Chronicles: Cool Critters of New Hampshire – Maybe sometime  we’ll put our camera, currently pointed at the birdfeeder, in another location….see what comes into our backyard. I know we have deer but there could be other things as well. Our camera already picked up what looked like a racoon on our deck.

Top 25 birds of the week: groups of birds – Beautiful birds…a good ‘last addition’ to the gleanings list this week.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!

Capturing CO2 from trucks and reducing their emissions by 90% -- ScienceDaily – Research applicable to making transportation friendlier to the environment…retrofitting of existing trucks.

Rising Temperatures Are Stressing the U.S. Corn Belt - Yale E360 – It’s not just rising temperatures…it’s the shift in rainfall causing hydrologic stress during the summer months. Maybe the ‘corn belt’ could shift northward?

Traveler Special Report: Threatened and Endangered National Parks – In Alaska and beyond…we are losing the natural treasures we sought to protect.

The history of candy canes and why they taste so cool – I am late getting around to including this in the gleanings list. I like peppermint candy year round…even if it’s not in the candy cane shape! I have peppermint candy chips to use in snow ice cream…if it will ever snow enough this winter here in Maryland!

Largest Electric School Bus Program in United States Launching in Virginia | CleanTechnica – Dominion Energy partnering with Virginia School districts…to achieve a 50% electric school bus fleet by 2025 and 100% by 2030. Good for the environment and the lungs of Virginia’s school children. I hope other states will move in the same direction.

These infrared images show just how alive butterflies’ wings are – Surprise! Butterfly wings have living cells not just membranes and scales! The living cells can sense heat and the butterfly responds behaviorally.

 Flame retardants and pesticides overtake heavy metals as biggest contributors to IQ loss - ScienceDaily – There are a lot of things that are toxic in our environment these days…and children are the ones that are hurt the most…and the hurt lasts their lifetime. This study looked specifically at lead, mercury, poly-bromated diphenyl ethers (PDBE…flame retardants) and organophosphate pesticides.

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

Unusual Urban Bobcat Spotted in Washington, D.C. | Smart News | Smithsonian Magazine – Wow! There is more open area where I live (between Washington DC and Baltimore)…maybe there is a bobcat around here too.

Low doses of radiation used in medical imaging lead to mutations in cell cultures -- ScienceDaily - Discovery that radiation creates breaks that allow in foreign DNA must be confirmed in animal studies. Maybe this is just a pathway to learning more about how cells cope with natural amounts of DNA damage….or maybe we need to look again at the risk/benefit of some routine diagnostic testing.

Stunning Chronophotos of Powerful Osprey in Mid-Hunt – Very dramatic!

Surprising Beauty Found in Bacterial Cultures – The video is less than a minute…worth watching.

Top 25 Wild Bird Photographs of the Week: #Feeding – National Geographic Society Newsroom – They all must eat. I kept track of what they were eating in the pictures: snail, insect or other small invertebrate, frog, rodent, fish, lizard, algae, carrion, nectar, skink, or seeds.

Walnuts may be good for the gut and help promote heart health -- ScienceDaily – I like walnuts….now just to eat them more consistently!

HEADING TO THE FOREST: Bringing Joy, Accomplishment & Hope to Children | Children & Nature Network – Forest days for kindergarteners and nature kids from preschool to high school…backyard to back country. More examples of how education in nature is happening. This was part 2…the earlier article can be found here.

America's most widely consumed oil causes genetic changes in the brain: Soybean oil linked to metabolic and neurological changes in mice -- ScienceDaily – Start reading labels….there is soybean oil is in a lot of processed foods like mayonnaise and salad dressings….the list goes on and on. Evidently other soy products (edamame, soymilk, tofu, etc.) don’t cause the same changes observed with soy oil.

Blue Jay: A New Look at a Common Feeder Bird – Our feeder is not accessible to blue jays….but we see them at our birdbath frequently….and hear their calls in the forest and our yard trees.

Macro Photography Shows Stunning Details of Carnivorous Plants – Some botanical pictures to finish out the gleanings for this week.

Top 25 Wild Bird Photographs of the Week: January 2020 – Starting out with wild and wonderful birds this week.

Infographic: How does nature influence human health? – Most people intuitively know that nature has a positive impact…but now there is more and more research to quantify that impact.

The Plastics Pipeline: A Surge of New Production Is on the Way - Yale E360 – Just when I really want manufacturers to find ways to package products in something other than plastic….the industry has plans to ramp up production of plastic. Consumers can still make a difference with our purchases (or lack of purchase). I’m slowly but surely reducing the items I buy that come in plastic….always looking for alternatives.

New aqueous lithium-ion battery improves safety without sacrificing performance: Non-flammable, cost-efficient, and effective battery -- ScienceDaily – Hurray for all the battery research going on right now….hopefully there will be more and better options near term. It would certainly boost the speed we can transition away from fossil fuels.

Pylos Tomb Artifacts Suggest Trade Links - Archaeology Magazine – Amber from the Baltics, imported carnelian, pendant depicting an Egyptian goddess….the Greek site might have been a stop on a trade route.

Happy New Year from Amundsen-Scott South Pole Station – Kelly Brunt posted this on January 3rd….and I just got around to looking at it. She was one of our hosts at NASA for my HoLLIE class and then the keynote for our graduation. It was good to read about her recent activities!

Super Resilient Protein Structures Preserved a Chunk of Brain for 2,600 Years – Wow – what an amazing and surprising find! And there is has been some research to figure out how it managed to be preserved.

Towards Ecophilia: Being hopeful in spite of it all -I enjoyed the pictures and activity descriptions about children in nature.

How US sewage plants can remove medications from waste-water – Using granular activated carbon and ozonation….more than 95% of certain antidepressants and antibiotics can be removed. This is important to help reduce the development of antibiotic resistant bacteria and maybe other environmental harms as well. But it can be expensive.

The oldest person in the world turns 117 – I liked the last paragraph of the story the best: Last year, when Tanaka received her record for the world’s oldest person, she was asked about the happiest moment in her long life. Her reply was simple: “Now.” Wouldn’t it be great if we all could feel like that no matter how old we are!

Earth at Night – This is an eBook from NASA that was last updated in December 2019….lots of pictures of the earth at night, analysis, and the technology behind the images.

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

Top 25 Wild Bird Photographs of the Week: Seabirds – Starting with the birds this week. I’m thinking about the Delmarva birding sessions later this month…they’ll be sea birds and more to see.

Clearing damaged cells out of the body helps heal diabetics' blood vessels -- ScienceDaily – Interesting….but still a lot of research needed before it could potentialy be used in treatment.

The toxic killers in our air too small to see - BBC Future – Nanoparticles – 90% of particles by busy roads are nanoparticles below 100nm. The smaller the particles, the greater potential toxicity. Anything smaller than 30 nm can make it to through the lungs and into the blood stream (larger than that doesn’t gets past the lungs). The Global Burden of Diseases study estimates that air pollution could account for 21% of all deaths due to stroke and 24% of deaths from ischaemic heart disease.

A little prairie can rescue honey bees from famine on the farm -- ScienceDaily – Food crops can provide good food for honey bees…but maybe not for the whole season.

Adult Humans Can Regenerate Cartilage: Study | The Scientist Magazine® - microRNA may have potential in human regeneration of tissue.

Agar Art Contest 2019: See this year’s winners – Art made with live bacteria.

Infrared Reveals Egyptian Mummies' Hidden Tattoos | Smart News | Smithsonian – 7 mummies – 3,000 years old. All the mummies with tattoos at the site were women.

Gabapentin: A Risky Answer to the Opioid Epidemic - The Atlantic Gabapentin has become the 10th most-commonly-prescribed medication in the US. It is viewed as a safer alternative to opioids for chronic pain….but it is problematic in combination with other sedating medication and it doesn’t work as well as hoped….particularly for back pain. It appears that looking for a quick fix for chronic pain is – again – not working as advertised.

Photography In The National Parks: My Favorite Spots For Great Photos – From Arches, Bryce Canyon, Big Bend, Acadia, and Padre Island.

Scientists Don't Know Why Freshwater Mussels Are Dying Across North America | Smart News | Smithsonian – It’s not just in one place….and may have multiple causes. But this just highlights that some mussel species that have already gone extinct…and our rivers are very different than their ‘natural’ state.

Scientists Use Agricultural Waste to Develop New Road Deicer - Yale E360 – Grape skins and other agricultural wastes rather than sodium chloride.

Poor Potato Crops Could Lead to a North American French Fry Shortage | Smart News | Smithsonian – Not a good year for potatoes in the US and Canada evidently. I wonder if prices will go up.

Hydration may affect cognitive function in some older adults -- ScienceDaily – Evidently overhydration has an impact on cognitive function as well…so it is important for older people to understand symptoms of both and actively manage their hydration.

Could Migraine Pain Relief Be Found In The Color Green? : Shots - Health News : NPR – Interesting research. Do green glasses help as much as the green LED light?

How everyday products are supercharging landfill gas, and what that means -- ScienceDaily – Some basic research that could be applied to getting more energy from our landfills.

U.S. States Have Eliminated Thousands of Environmental Protection Jobs Since 2008 - Yale E360 – “Neither EPA nor states have the funding they need to meet their responsibilities under the Clean Air Act, Clean Water Act, and other laws that protect the public’s health and our environment from dangerous pollution.” Not good.

How hacking the human heart could replace pill popping - BBC Future – Pacemakers are primitive compared to the devices that are being worked on now. The future implants will adjust to the situation…reading and writing to the nervous system to treat such things as diabetes, bladder control and chronic pain (and heart issues). Maybe they will address the root cause of some chronic diseases rather than just the symptoms.

Colouring Europe at Work: download our industrial heritage colouring book | Europeana Blog – Learn some history while your color.

IBM Changes the Energy Storage Game With Cobalt-Free Battery – Lots of research in the battery arena these days. This one caught my eye since I spent some of my career working for IBM. Maybe these will be part of the next-gen technology for batteries.

Tiny shells reveal waters off California are acidifying twice as fast as the global ocean -- ScienceDaily – Looking at shells of foraminifera in sediments provides a vertical record of ocean acidity.

Top 25 Wild Bird Photographs of the Week: Colourful Birds – National Geographic Society Newsroom – Starting off this last gleanings list of 2019 with birds! My favorite picture of this set is the scarlet macaw with a stick. Is it eating it or using it as a beak-pick?

Artistic Photographs of Mushrooms and Myxomycetes by Alison Pollack – Focusing on small things in the forest.

In Search of Australia’s Amazing Rainbow Finch – A bird survey experience…and some pictures.

Patchwork of Corn in the Snow – As of late November a lot of corn was unharvested because it was too wet. Corn needs to dry on the stalks before it is harvested and this 2019 crop may not be harvested in some areas until February or March of 2020.

Watching Wildlife on Skis – Winter wildlife….another benefit to being out and about (with proper gear) during the winter.

Life Rides the Wind in the Desert | The Scientist Magazine® - Finding life in the Atacama Desert.

Decking the halls of history: the origins of Christmas decorations – A little historical note for after the holiday.

Liver cancer deaths climb by around 50% in the last decade -- ScienceDaily – Survival rates are low too. Obesity and smoking are two preventable causes.

How Climate Change Will Affect Maryland's Birds | Audubon – I looked at the page for Maryland because that is where I live. The red-headed woodpecker is on the ‘high vulnerability’ list. The data is available for other states as well (scroll down on the ‘home’ page and select by state or zip code). The red-headed woodpecker appears on the high vulnerability list for Texas and Missouri too (those are two other states I checked).

First Global Map of Saturn's Moon Titan Reveals Secrets of Earth's 'Deranged' Twin | Smart News | Smithsonian – There are plains, sand dunes, mountains, labyrinthine valleys…and lakes of methane.

'Self-cleaning' concrete could keep buildings looking new -- ScienceDaily – Maybe a new building material…but can it be made in a ‘green’ way?

Everything You’ve Ever Wanted to Know About Turkeys – I’m just catching up on some reading…this would have been more appropriate for the Thanksgiving week gleanings…but better late that never. Turkeys are interesting birds!

Air Pollution Tied to Brain Cancer: Study | The Scientist Magazine® - Combustion-related nanoparticles can reach our brain! The concentrations of these particles in highly polluted areas are also causing other health related problems as well. For example, the air pollution in Kabul, Afghanistan may be causing more deaths than war in that area

Owling: A Field Guide to Finding Winter Owls – Seen any owls? They are often easier to hear than see.

Slideshow: Images from The World Beneath | The Scientist Magazine® - A few pictures from a new book about sea creatures and coral reefs. Lots of vibrant color and camouflage.

Eating in sync with biological clock could replace problematic diabetes treatment: An early-morning, carb-filled meal improves glycemic control among diabetics -- ScienceDaily – We are shifting our meals…largest one at midday…smallest one at night. If we eat a high carb meal it will be at breakfast. I had gingerbread cake this morning!

Sunlight-Tracking Polymer, Inspired by Sunflowers, Could Maximize Solar Power | Smart News | Smithsonian – Another way that solar panels can gain efficiency.

Springfield Plateau: Yellowjacket Nest – A yellowjacket tale from Springfield MO. I was surprised that ice was the treatment for a sting. I’ve always used baking soda with ice as the backup plan if there isn’t any baking soda available.

Why biodegradables won’t solve the plastic crisis - BBC Future – There are only pieces of a solution at this point….nothing comprehensive. It seems like the best strategy for at home is to reduce all single use plastic as much as possible. There are some easy things like reusable shopping and produce bags, but it becomes hard quickly. So many groceries and toiletries only come in plastic containers.

Remote Sensing Data Advances Soil Health Science – Cover crops and no-till practices were an advantage in record-breaking rainfalls of spring 2019.

How the House Finch Conquered Your Feeder…and A Continent – A little history of House Finches – originally from the southwest and Mexico…now in found widely across North America.

How the Aztecs could improve modern urban farming: Chinampas: An old technique might provide new solutions to sustainable urban agriculture -- ScienceDaily – The article made the multiple harvests per season seem feasible in tropical wetlands…not so much in the temperate zone where the artificial islands would go through a real winter although maybe it would just mean the use of cover crops during that time period.

Top 25 Wild Bird Photographs of the Week: December – Bird photography to enjoy!

Listening to Nature: The Emerging Field of Bioacoustics - Yale E360 – An up and coming technology for remote sensing of birds, insects, frogs and other animals.

Red Tides Under the Microscope | The Scientist Magazine® - It’s surprising what we don’t yet know about the organism responsible for red tides – Karenia Brevis. Spanish explorers of Florida in the 15th and 16th centuries described fish kills in Gulf waters. The first official documentation was in 1882 – published in the Proceedings of the US National Museum. This article is about what we know….and where more research is needed.

The woman who reshaped maths - BBC Future – Hilda Geiringer…a refugee from the Nazis. A BBC Future column celebrating a ‘missed genius’ whose contributions are still notable in the world today.

NOAA weather balloons find no zero-ozone regions above South Pole during 2019 ozone hole season | NOAA Climate.gov – A little science…a little history…a projection. The positive message – if the trend continues, it’s estimated that the ozone layer will recover around 2070.

Abrupt shifts in Arctic climate projected: Likelihood of an abrupt increase in wildfires also noted -- ScienceDaily – With specific modeling of permafrost as it continues to degrade….it appears that the changes won’t be as gradual as  previously assumed.

Lake On Bottom Of Halema‘uma‘u Crater At Hawai'i Volcanoes National Park Now Bigger Than Football Field – The lake was noticed back in July….and is being studied with instruments on drones. More information is at the National Park Service site for the park.

Top 25 Wild Bird Photographs of the Week: Wild Birds – National Geographic Society Newsroom – I always enjoy the bird photography compiled by National Geographic every week.

Offshore Wind Has the Potential to Fulfill Global Electricity Demand 18 Times Over - Yale E360 – Hurray for this potential….the transition is the challenge.

AP: At least 1,680 dams across the US pose potential risk – There is a link to an interactive map that shows where the 1,680 dams are located. The last paragraphs of the article are the most troubling. There are a lot of dams with unknown status. Roughly 45% of Texas dams are exempt from regulation…in Missouri safety inspections are only done on 650 of its more than 5,000 dams. And states that know about problematic private dams often can’t identify the owners to address the dam’s issues.

Aging in good health: The inequalities are widening -- ScienceDaily – A study with over 11 million people tracked for 25 years!

Susquehanna Sediment in the Chesapeake Bay – Imagery of big rivers and the Chesapeake Bay after a storm at the end of October…. close to where I live. On a positive note - the sediment (even after the record rains earlier this year) has not damaged the underwater grasses on the Susquehanna Flats as much as was initially feared.
