Gleanings of the Week Ending December 25, 2021

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.

New copper surface eliminates bacteria in just two minutes – One of the emerging technologies to fight bacteria (and viruses) without antibiotics. Copper is already being used in some applications, but this materials research developed a new structure of copper that is more effective and faster. The article didn’t comment about durability…but still very promising finding.

Home Battery Storage: The (Solar) Rich Get Richer – There is beginning to be more equity in solar panel installation….but storage is still a challenge at lower incomes. Some states have programs that may be the wave of the future and there are incentives in pending legislation. Hopefully a positive momentum will build over the next few years.

California Readies Launch of Largest Food Waste Recycling Program in the U.S. – Part of the county where I live in Maryland has curbside pickup of food waste for composting…but not the part where I live. I have a backyard compost bin…but many people do not so there is still considerable food waste going to the landfill.

10 Winter Birds to Spot During the Christmas Bird Count – Seen any of these in your area?

Why is snow white? – 3 videos…the last one with more ‘bonus’ explanations (such as why polar bears are white).

Top 25 birds of the week: Bird Pigment – This post was a bit confusing since it wasn’t explicit about which colors were from pigments ( as in the red of cardinals) and which were from light scattering caused by the physical structure of the feathers (for example, in blue jays). Read more about this non-pigment phenomenon particular for blue feathers here.

Winter is coming: Researchers uncover the surprising cause of the little ice age – New research shows that the little ice age in the early 1400s occurred when the Atlantic Meridional Overturning Circulation (AMOC) collapsed after a warming period which flushed Arctic ice into the north Atlantic, cooling it and reducing its saltiness. Could the AMOC collapse again with ice melting because of climate change? Existing climate models do not model the impacts of ice melt (making the north Atlantic cooler and less salty)!

From blood clots to infected neurons, how COVID threatens the brain – An overview of the research into how COVID-19 impacts the brain; there is still a lot more to be learned about this - probably one of the most devastating aspects of ‘long Covid’. It appears that the cognitive impact experienced by some COVID-19 survivors improves over time, but half the patients in one study were not back to normal after a year. It is a very sad prospect for individuals and for or society.

Watch This Giant Phantom Jellyfish With 33-Foot-Long Arms Float Through the Deep Ocean – The video is less than a minute…worth watching.

AAA Electric Vehicle Infographic — The Good & The Bad – My current car is a plug-in hybrid….the next one will most likely be an EV.

Gleanings of the Week Ending February 13, 2021

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

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

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

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

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

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

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

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

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

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

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

Gleanings of the Week Ending February 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.

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.
