Top 25 birds of the week: Green Colours! – So many beautiful birds…

150-Year-Old Boxwoods Lost To Blight At Carl Sandburg Home – My daughter and I visited the Carl Sandburg Historical Site in 2003 when we were on our way from Maryland to meet family members coming from Texas for a Georgia vacation. It was the first time I had driven a car with a nav system! We enjoyed walking the grounds and touring the house more than we expected. It’s sad that the boxwood there will be cut down.

What early-budding trees tell us about genetics, climate change -- ScienceDaily – Our plum and cherry trees are the ‘fruitless’ kind but they were in full bloom when our temperatures dipped into the mid-20s. I wonder how many orchards are going to have less fruit this year.

Hope and Peril for North America’s “Snow Parrot” – A parrot that lives in pine forests. Their range once extended into the US from northern Mexico, but they’ve been gone since the 1930s.It’s only in the past few years that their migration and winter grounds in the Mexican state of Durango have been discovered. There are efforts to safeguard the free-living birds and continue captive breeding programs in zoos (like the San Diego Zoo) with the plan to begin reintroducing birds into the wild in the future.

The Kodak Brownie: The Camera That Made Photography Accessible – My mother was taking pictures of her siblings in the 1940s….with a Brownie. There is one of her twin sisters (maybe 4 or 5 years old) peeking over the windowsill of the bathroom window (they were standing in the bathtub!); I always wondered if she had help on the inside positioning them while she got outside to get the picture. It must have been a warm day since the window was open!

Dangerous landfill pollutants ranked in order of toxicity -- ScienceDaily – The technique can help landfill managers mitigate risk for a particular site rather than taking generic actions that might not address the biggest problems.

For the First Time in 75 Years, a New Invasive Species of Mosquito Was Found in Florida | Smart News | Smithsonian Magazine  - The mosquito that can carry yellow fever and other diseases was found in Florida last year. That does not bode well for keeping tropical diseases at bay in the US as the climate continues to warm.

Scythian people weren't just nomadic warriors, but sometimes settled down: Varied diets and limited mobility challenge stereotypes of ancient steppe populations -- ScienceDaily – Not all Scythians were nomadic. The majority of them might have remained local…farming millet and raising livestock!

Lessons from Darwin's "Mischievous" Birds | The Scientist Magazine® - The striated caracara of the Falkland Islands…we’re familiar with the crested caracara from the south Texas.

Newly Restored Pompeiian Frescoes Capture Hunting Scenes in Vivid Detail | Smart News | Smithsonian Magazine – Part of an ongoing conservation initiative funded largely by the European Union launched in 2012.

New wearable device turns the body into a battery -- ScienceDaily – I’m always forgetting to charge my Fitbit until the low battery warning message comes up. It would be great to never need to charge it!

Soot from Asia travels express on a highway to the high Arctic : Research Highlights – Soot in the Arctic traced back to its source.

Working outdoors linked to lower risk of breast cancer among older women -- ScienceDaily - Outdoor workers are able to make more vitamin D which may be protective, say researchers. This is an observation…but might indicate a thread for future research.

World's first dinosaur preserved sitting on nest of eggs with fossilized babies – An fossilized Oviraptorosaur, a bird-like theropod, found on a nest filled with its 24 eggs.

Stealth Chemicals: A Call to Action on a Threat to Human Fertility - Yale E360 and Air pollution: The silent killer called PM 2.5 -- ScienceDaily – Products of human ingenuity that are negatively impacting our health.

94% of older adults prescribed drugs that raise risk of falling: From 1999-2017, more than 7.8 billion fall-risk-increasing drugs were prescribed to older adults in the US, and deaths from falls doubled -- ScienceDaily – In my 50s, my doctor prescribed a blood pressure medication that made me dizzy. When I complained about it (citing the danger of becoming dizzy and falling down stairs being a greater risk than the benefit of lowering my blood pressure to the level she was attempting), she decided I didn’t need the medication since I was taking half the lowest dose tablet. I hope that the medical professionals prescribing the fall-risk-increasing drugs are more careful about how they are using them now for older people particularly…but for younger people too. Sometimes it seems like the trend is to always ‘treat with drugs’ to address a specific problem rather than integrating for the overall health of the individual.

Was This Helmet Worn by an Ancient Greek Soldier During the Persian Wars? | Smart News | Smithsonian Magazine – Found by a dredging vessel off the coast of Haifa, Israel.

50 Birds: Adventures in Backyard Birding – Birding can be done anywhere. Many people have discovered the joy of bird watching from home during this pandemic year.

Joshua Trees: An Uncertain Future For A Mojave Desert Icon – A big fire and climate change….are the Joshua Trees doomed?

Health declining in Gen X and Gen Y, US study shows -- ScienceDaily – The long-term trends are not positive; the US was already seeing decreases in life expectancy and increases in disability/morbidity pre-pandemic. The study pointed to the increase in unhealthy behaviors over the past decades that medical treatment cannot overcome. Based on the response to public health measures attempted in the US for the pandemic, it’s difficult to be optimistic that any kind of intervention could be broadly effective.

How the Loss of Soil Is Sacrificing America’s Natural Heritage - Yale E360 – At best 24% of Corn Belt topsoil is gone…at worst 46%....and topsoil is still being lost. The study found that the main source of erosion is not water runoff but tillage…and right now only 15% of acreage in the heart of the Corn Belt is ‘no-till.’

Oldest Known Wild Bird Hatches Chick at Age 70 | Smart News | Smithsonian Magazine – Wisdom, an Laysan albatross, returns to Midway Atoll again. Her chick for this year hatched on February 1. She has outlived the person that originally banded her!

Diets high in fructose could cause immune system damage, study suggests -- ScienceDaily – Another reason to avoid processed foods….

Easy Nature Adventures to Enjoy Near You – Enjoying the place where you are…outdoors! This time of year, there is a lot of things to see close to where I live and I can choose the places/times to avoid any crowds (still a good thing in this pandemic time until the vaccination rates get much higher and infections begin to plummet).

Stealth Chemicals: A call to action on a threat to human fertility – Evidence has been accumulating…and there are a lot more observable problems at this point. I was glad that near the end of the article, there were recommendations for people trying to have children and/or for young children. And we need to move forward on top-down approaches if manufacturers don’t take near term action.

Helping Birds Adapt to Climate Change in the Nevada Desert – Replacing lost riparian areas after removal of invasive tamarisk.

Earth Matters - What in the World Are Moon Trees? – Trees grown from seeds that were taken into lunar orbit 50 years ago!

Climate Change, Deforestation Hurting Monarch Butterfly Migration : NPR – So many problems for the migrating populations of these butterflies. Soon we might only see this butterfly in areas where they don’t need to migrate to survive the winter.

Remnants of Iron Age Settlement, Roman Villa Found in England | Smart News | Smithsonian Magazine – 15 cone shaped roundhouses dating from 400 BC and 100 BC and then a Roman villa from the 3rd to early 4th century AD. It must have be a good place to call home over a long time period!

Top 25 birds of the week: March 2021 – Starting off the gleanings for this with bird photographs. I found myself looking at eye color as I enjoyed this group of 25.

Satellite imagery shows northern California kelp forests have collapsed – I had read a story about this previously….but this article include visuals: satellite image and underwater images of what it look like before…and the urchin barrens that are there today.

Kauri trees mark magnetic flip 42,000 years ago | Science – Analysis of a tree preserved in a bog. It lived during the Laschamp Excursion (the last time the poles flipped) The climate instability lasted about 500 years.

Giving Wildlife Room to Roam in the Face of Climate Change – The importance on microhabitats in wildlife conservation particularly as climate changes.

Small Particulates From Burning Fossil Fuels Kills 8.7 Million People Each Year – And this is a form of pollution no one escapes….unless you choose to live in an enclosed and continuously filtered environment (like on an planet that does not support life as we know it). Right now, there are areas outside cities that have lower levels of the small particles in their air but eventually the continued increase in particles and circulation within the atmosphere will spread the ever increasing particles over the entire planet.

Even for Solitary Squirrels, It’s Better to Know the Neighbors – Red squirrels that have the same neighbors year after year…live longer! The study was done in a remote area of Canada over 22 years.

Thanks to Etsy, You Can Now Purchase a Gee's Bend Quilt Online for the First Time | Smart News | Smithsonian Magazine – Folk art…museums…and a modern outlet to improve the artists’ ability to sell their work.

America’s First National Wildlife Refuge – Pelican Island National Wildlife Refuge….I’m including it in our plans for the next time we go to Florida; it’s about 1.5 hours to the south of Merritt Island National Wildlife Refuge which is always one of the places we visit in Florida.

Highly functional membrane developed for producing freshwater from seawater: A desalination membrane laminated with nanosheets featuring 2D nanochannels -- ScienceDaily – Still in the research stage. Maybe this is one of the technologies that will enable low-energy desalination - something we will need to avoid water shortages in many areas of the world.

A mild way to upcycle plastics used in bottles into fuel and other high-value products -- ScienceDaily and How Paving with Plastic Could Make a Dent in the Global Waste Problem - Yale E360 – Two articles about uses for the plastic waste that is overwhelming the planet right now. There still needs to be significant testing on plastic for paving: will it withstanding heavy traffic…will it shed microplastic particles, etc.

Pompeii's Museum Reopens With Dazzling Display of Archaeological Treasures | Smart News | Smithsonian Magazine – I enjoyed the article…and the website for the new museum.

A large number of gray whales are starving and dying in the eastern North Pacific -- ScienceDaily – Ongoing research but one explanation being explored in a decline in prey (i.e. amphipods) availability in their Arctic feeding grounds – maybe caused by warming there due to climate change.

For the Birds: Why Designing for Birds is Good for Everyone - News | Planetizen – Fast Company interviewed Tim Beatley about his book; he was one of the speakers at the Birds on the Niagara conference.

Wombats Poop Cubes, and Scientists Finally Got to the Bottom of It | Smart News | Smithsonian Magazine – Over 40,000 contractions as the feces moves down the intestine to shape a very dry cube. Evidently the cube shape is an indicator of wombat health!

Water Warning: The Looming Threat of the World’s Aging Dams - Yale E360 – Lots of people live downstream from big dams. Yikes! Decommission of dams is not easy…arguably it could be harder than the building of the dam originally.

Thousands of Wild Bee Species Haven't Been Seen Since 1990 | Smart News | Smithsonian Magazine – Most of the data came from Europe and North America….with some from the rest of the world. All of it sums up to a grim picture when it comes to bees.

Top 25 birds of the week: Bird Interactions! - Wild Bird Revolution and Top 25 birds of the week: Raptors!  and Top 25 birds of the week: Feathers!  – A treat this week – 75 bird photographs – enjoy!

The unseen 'slow violence' that affects millions - BBC Future – The harms that happen so slowly that we don’t notice in the moment. It happens over months and years and decades (maybe even centuries). We notice as we use our ‘big data’ to see hot spots of ill-health, where the environmental degradation is at it’s worst, and populations that can’t seem to escape their dire situation. And the issue very quickly becomes – how does our culture respond to the awareness of that ‘slow violence.’

Carbon: Getting to net zero -- and even net negative -- is surprisingly feasible, and affordable -- ScienceDaily – A detailed model of the entire US energy and industrial system….showing how to achieve carbon neutrality by 2050…with particular emphasis on what needs to happen in the next 10 years.

The country rejecting throwaway culture - BBC Future – France has introduced an index of ‘repairability’ rating for appliances…hoping to increase the electronics repair rate to 60% within 5 years. I’m glad I opted to repair my clothes drier rather than replace it….although the repair (replacing of the failed heating element) produced some trash it was a lot less than the whole appliance! Things like phones and laptops and monitors are harder.

Carolina Wrens Will Nest in Just About Anything and Why Carolina Wrens Have Moved into Your Neighborhood – We had a Carolina Wren make a nest in a gas grill we hadn’t used in along time. It surprised me when I opened the lid and the bird – startled and then panicked – flew out onto the deck railing. There is usually a pair nesting somewhere around our yard; we see them when they come to the feeder and hear them even more frequently. The forest behind our house and the brush pile at the edge of the forest are good places for them.

Federal Funding Obtained to Replace Zion National Park's Shuttle Fleet – And they’ll be electric! What a great way to keep the air smelling like nature rather than combustion fumes!

Rare Yellow Penguin Photographed for the First Time | Smart News Science | Smithsonian Magazine – What an unusual looking bird! It’s a king penguin on South Georgia Island with leucism, a condition where melanin is only partially lost and some parts of the body retain color. In this case…the ability to produce the usual black pigment is missing.

New River Gorge is America's Newest National Park - News | Planetizen – This park is within ‘road trip’ distance from where we live….maybe a destination post-pandemic.

How we turned a golf course into a haven for rare newts, frogs and toads – Hopefully US golf courses are doing things like this too. I usually think of them as using a lot of chemicals and would not want to live near a golf course….but if they consciously made places for amphibians….it would mean that other creatures could survive in the space too. There is an Audubon International Certification program for golf courses but they don’t publish a list of course that are certified.

The Arctic Ocean might have been filled with freshwater during ice ages – Based on a geochemical study of sediments.

Top 10 things we learned about climate change in 2020 – I’m thinking about this more this week with the extreme cold in Texas…and lack of preparedness of utility companies and state governments. It drives home the overarching message now: doing nothing will cost more than doing something.

Top 25 birds of the week: Seabids! – Birds and water…from around the world.

Size, Shape, and diversity in phytoplankton – The tiny organisms that could be changing in warming, more acidic oceans….do we have enough of a baseline to know if these communities are changing in ways that will impact the food networks of our oceans?

Fairy Shrimp – A video from a vernal pool in Pony Pasture Rapids Park in Richmond, Virginia.

Wintering bird communities track climate change faster than breeding communities in Europe and North America – Weather impacts birds in the short term (my family has commented that they have seen flocks of robins in their neighborhood recently….having not seen them in the past 30 years they’ve lived in the area) but the longer term impacts of climate changes are only observable with large data bases built since the 1980s. This study looked at over 1,200 species of birds!

How to see the red fox in winter – We occasional see red fox in our neighborhood but I haven’t seen any (so far) this winter. Maybe after the snow/sleet is over I’ll take a walk and look for tracks.

Age provides a buffer to pandemic's mental health impact, researchers say -- ScienceDaily – It may not be ‘age’ as much as older people being more able to stay at home and avoid other people (stress reduction through conscientious steps to avoid COVID-19 exposure)….whereas young people are more likely to have to get out and about for work or other obligations. It could be difficult for older people living along…but maybe we have quite a few older people that are not alone in their ‘bubble.’

Sunset Crater's Explosive Past – The youngest of the volcanoes in the 1,800 square mile San Francisco Volcanic Field near Flagstaff, AZ. It’s a place I visited (and posted about) back in February 2015.

Immune driver of brain aging identified -- ScienceDaily – It seems to be a change in how myeloid cells handle glucose….tending to hoard it rather than using it for energy. I wondered if that is why people with diabetes are at increased risk for cognitive decline.

Magnetic fields detected in Venus Flytraps – A small magnetic field is produced when the trap closes!

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?

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.

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

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

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

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

Top 25 birds of the week: Colouration! - Wild Bird Revolution – Lots of color in this post to break up mostly brown and white winter color outside my window! 

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

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

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

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

I am featuring videos this week….including the newest baby panda in the US and historic houses. I discovered that a lot of house-type museums have increased their virtual content during the pandemic. The historic houses I picked for this post are ones I have visited in the past. Some I have visited more than once (Mount Vernon and Monticello, for example). It’s fun to savor them virtually!

Panda Cub’s virtual debut – From the National Zoo…video is just over 2 minutes

Virtual visits to the Newport Mansions -  3D tours From the Preservation Society of Newport County. Includes The Elms, Marble House, Hunter House, Isaac Bell House, Chateau-ser-Mer, Chepstow, and Kingscote.

Diet and lifestyle guidelines can greatly reduce gastroesophageal reflux disease symptoms -- ScienceDaily – Exercise seems to be important – perhaps because it helps clear stomach acid that causes heartburn symptoms.

Top 25 birds of the week: Wild birds Photos! - Wild Bird Revolution – Birds – always great to look at in the wild and in photos.

How Codebreaker Elizebeth Friedman Broke Up a Nazi Spy Ring | Smart News | Smithsonian Magazine – Some history…about how a woman did work she wanted to do…made significant contributions…didn’t get credit or pay that she should have. It happens again and again. We can’t assume that it isn’t still happening just because we have some very visible examples of women with power, recognition, and pay.

Are sleep trackers accurate? Here's what researchers currently know – It’s not always good to track sleep….particularly if it causes anxiety. I am in the group that generally has good sleep, so the tracker data doesn’t cause me anxiety, but it probably doesn’t improve anything either!  I might get a much simpler tracker next time that doesn’t provide sleep metrics.

The Wintertime Wonder of Unusual Ice | Smart News | Smithsonian Magazine – The short video of hair ice forming is interesting.

How Africa's largest city is staying afloat - BBC Future – Lagos, Nigeria. Part of the city is known as the ‘Venice of Africa.’ And there is a ‘Great Wall of Lagos’ to reinforce the coast.  The claim is that Africa’s largest city is leveraging its ingenuity to stay afloat….but whether it succeeds in the coming decades will be the real test.

Wingspan and Other Tabletop Games for Naturalists – A new indoor activity for during the winter?

Square Structure Detected Under Monte Albán’s Main Plaza - Archaeology Magazine – The plaza was in use for 1,000 years….and evidently the structure detected with ground penetrating radar, electrical resistance and gradiometery is 60x60 feet…and about 3 feet thick. More study of the data might reveal if the building had stairs, tunnels, and columns.

Leaf microbiomes are a neighborhood affair in northern forests -- ScienceDaily – The microbes associated with trees have been an active research area in recent years. This study looked at Sugar Maples and discovered that their microbiome was similar to the trees around them…whether it was other sugar maples or conifers….other species entirely.

A warm pool in the Indo-Pacific Ocean has almost doubled in size, changing global rainfall patterns | NOAA Climate.gov – The impacts on large-scale atmospheric circulation and rainfall are expected to intensify in the future.

Top 25 birds of the week: January 2021 – This collection includes a photo of a red-breasted nuthatch…a bird we’ve seen at our feeder this year!

Photographer Nathan Myhrvold Captures Snowflakes in High Resolution – I enjoy trying to photograph snowflakes…but I do it close to home where the challenge is higher temperatures. That tends to cause them to clump rather than be easily separated into single flakes. It’s still a fun activity for snow days.

New mammogram measures of breast cancer risk could revolutionize screening -- ScienceDaily – Improving the way mammograms are analyzed…giving results at the time of screening instead of later then moving toward personalized screening thereafter rather than ‘one size fits all.’ I wonder how long it will take for this to trickle through the industry.

Flapper style | Europeana – Our family has a picture of one of my grandmothers in a flapper dress. She probably made it herself – as the article indicated…they were easy to make and patterns were available. The dresses have a timelessness to them even though they are associated with the 1920s. They look great as party dresses even 100 years later!

'Sparkling' clean water from nanodiamond-embedded membrane filters -- ScienceDaily – The problem the researchers are addressing is filtering of the hot water from oil recovery and other industrial processes. We’ll need more technologies like this to clean up water we can’t afford to leave polluted forever….but we should concurrently move toward technologies that don’t leave toxins in water. Technologies should be designed with the goal in mind of 0 waste.

Researchers Catch Oldest Tropical Reef Fish Known to Science | Smart News | Smithsonian Magazine – An 81-year-old midnight snapper! They also caught a 79-year-old red snapper in the same area. Climate change is already warmed the reef enough that the life-span of the fishes there is expected to be shorter in the future. The record for oldest known vertebrate in the world is also a sea creature – a 400 year old Greenland shark.

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.

Coronavirus FAQ: How Do I Protect Myself From The U.K. Variant? - I added this one at the last minute…it’s scary…a good prompt to evaluate the precautions you are taking to not get COVID-19 with this more contagious variant circulating in the US. We are so close to having vaccinations broadly available!

When Only a Hippopotamus Will Do – Learn a bit about hippos. Did you know that there is a ‘wild’ population of hippos in Columbia’s Magdalena River, escaped from Pablo Escobar’s menagerie after his death?

Plastics pose threat to human health, report shows -- ScienceDaily – Awful….and there is relatively little being done to control this source of toxins in our environment.

Top 25 birds of the week: Terrestrial Birds! - Wild Bird Revolution – Most of the birds are relatively drab – lots of browns and off-white feathers….but interesting patterns. - the better to blend in with their environment. But there are a few surprises that are quite different from the rest.

From Ancient Rome to Contemporary Singapore: The Evolution of Conservatories – THE DIRT – I like conservatories….this article includes some history that I hadn’t thought about before…a bit more from the perspective of how conservatories fit into the cultures that created them.

Operation Ponderosa: Saving a Forest, Pandemic Edition – Several reasons this article caught my attention: it’s about 1) the Davis Mountains in Texas…a location I’ve driven through on road trips between Dallas and Tucson, 2) fieldwork and also done by a woman during this pandemic year, 3) the Ponderosa pine’s importance as ‘sky islands’ in this arid part of the country, 4) the impact of fire, and 5) how genetic testing informs forest restoration efforts.

Trees are out of equilibrium with climate -- ScienceDaily – I might have gotten a bit stuck on trees for this gleanings collection. This study found that factors other than climate often limit where trees grow...that few trees grow everywhere the climate would appear to support their growth.

Ancestral Puebloans Survived Droughts by Collecting Water from Icy Lava Tubes | Smart News | Smithsonian Magazine – New Mexico’s El Malpais….a place I’ve visited several times.

Migration and disease in the Iron Age - Current Archaeology – A skeleton of a man with tuberculosis that died between 400 BC and 230 BC in Britain but was born elsewhere based on analysis of his molars that developed in early childhood. Did he contract the disease early in his life or after he arrived in Britain?

Canyon De Chelly, Walnut Canyon Park Pages Added to Traveler – I’ve been to both these places so was glad they were added list of Essential Park Guides on this site. The guides are collections of articles about each park…and good references when planning a visit or to see some pictures of the park!

Bowerbirds: Meet the bird world’s kleptomaniac love architects – Elaborate structures of sticks and often colorful found objects…to attract a mate.

Gleanings of the Week Ending January 2, 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.

2020 Year In Review: Top Stories From Around The National Park System – Issues discussed in the post: COVID-19, Great American Outdoors Act, border wall, invasive species, wildlife issues, climate change, crowding in the parks, wildfires.

New Discoveries in Human Anatomy | The Scientist Magazine® - So much study of human anatomy over the years….and there are still new discoveries.

50 Satellite Images from 50 Years of NOAA | NOAA National Environmental Satellite, Data, and Information Service (NESDIS) – Visuals from NOAA – beauty, science, education….so much has happened over the 50 years of NOAA’s existence.

2020 Year In Review: Parks, A Pandemic, And Photography – Lots to see in the National Parks…I hope to be able to get out and see some in-person before the end of 2021.

Top 25 birds of the week: Birding! – Wild Bird Revolution  - And I want to travel to some birding festivals too!

Recycled concrete could be a sustainable way to keep rubble out of landfill: Can even outperform traditional construction, says researcher – ScienceDaily – A Canadian study…seems like the results should be pertinent to the US too. The research indicates that “recycled concrete can be a 100% substitute for non-structural applications”….and might also be a substitute within more structural applications as well if innovations in the composition of recycled concrete continue.

Top 10 States For Renewable Energy, & Their Renewable Energy Splits  - Interesting mix of states on the list with quite a difference in the amount of hydro, wind, solar, geothermal, and biomass among the top 10. California is the only one with all 5. But there are 5 states that have 4 of the 5.

Scientists reverse age-related vision loss, eye damage from glaucoma in mice – ScienceDaily – Hopefully this research will translate into treatment for people.

Take a Virtual Tour of the World’s Largest Circular Tomb, Augustus’ Mausoleum | Smart News | Smithsonian Magazine – The virtual tour takes a little bit to load….but is worth it. Note that the ‘chapters’ are along the bottom of the screen.

Desalination breakthrough could lead to cheaper water filtration – ScienceDaily – Increasing efficiency of reverse osmosis filters by beginning to better understand how they work. This is something that will be more important as climate change and our own production of pollutants makes obtaining clean water more challenging.

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.

35 Beautiful Winter Scenes to Get You in the Holiday Spirit – We had our first snow a little over a week ago…our Christmas was windy and rainy….I enjoyed these snowy pictures from around the world to get me back into the ‘winter wonderland’ mood.

Time capsule for 2020: the 37 objects that defined the year – This prompted me to think about what objects represent the year for me…maybe just a top 10 though rather than 37!

Top 10 Discoveries of the decade – From Archeology magazine

NOAA Research’s top 5 stories from 2020 – NOAA models track smoke movement – and locust swarms; scientists explore the impact of the COVID-19 response on the environment; carbon dioxide continues to rise; Dungeness crab larvae are already showing effects of ocean acidification; and a new roadmap for tracking ocean and Great Lake acidification

Top 11 Clean Energy Developments in 2020 – Some good news….nice to find these in a year that was dominated by bad – sad – horrific news (pandemic, fires, hurricanes, cultural/political strife).

Glucosamine may reduce overall death rates as effectively as regular exercise, study suggests -- ScienceDaily – It’s a correlation finding…not cause/effect. But the correlation was found by assessing data from over 16 thousand people over 40 years of age.

In boost for renewables, grid-scale battery storage is on the rise – Another good news story.

Photography in the National Parks: Winter Wonderlands – More wintery pictures of beautiful places.

Stonehenge's Continental Cousin - Archaeology Magazine – Archaeology in a German potato field! Evidence of concentric rings of oak posts, graves, pits filled with sacrifices, a village of long houses near the circle, alignment with sunrise on days halfway the solstices and equinoxes….no fortification.

Top 25 birds of the week: Bird Camouflage – Ending this gleaning list with birds. There lots of birds that blend into their environment!

Gleanings of the Week Ending December 19, 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.

How Has Photography's Relationship With Nature Evolved Over the Past 200 Years? | Smart News | Smithsonian Magazine – A little history…that I used as a prompt to look for some of the works on Internet Archive. I’ll post about what I found for Kazumas Ogawa in a post next week.

Infographic: Deciphering Diet from Blood and Urine Samples | The Scientist Magazine® - Full article also available and more interesting that the infographic! The approach is still not perfected…but it may eventually help us get to personalized nutrition plans without as much trial and error that is required now.

Connection between gut bacteria and vitamin D levels -- ScienceDaily – Lots more needed to understand Vitamin D. This study indicated that blood tests for Vitamin D might not be useful at all since they don’t measure active Vitamin D….and active vitamin D is what correlates to gut bacteria…and potentially bone health. “Maybe it’s not how much vitamin D you supplement with, but how you encourage your body to use it.”

Get a Bird's-Eye View of UNESCO World Heritage Sites Across the Globe – Some beautiful places…from overhead.

How Non-Native Plants Are Contributing to a Global Insect Decline - Yale E360 – Insect declines….then birds. Lots of reasons to focus on planting natives a much as we can. I’m glad the forest behind my house is full of native trees and that I’ve replaced 2 bushs in the front of my house with natives. The challenge is to control the small but prolific invasive plants growing on the forest floor and into our yard enough for non-natives to survive. There used to be native jack-in-the-pulpits in our forest until several years ago.

How do we separate the factual from the possible? New research shows how our brain responds to both -- ScienceDaily – This article was frustrating. The study found that factual language is something our brains respond to. That’s not the issue at this moment in our nation’s history. The problem is the use of factual language about something not factual! Maybe this article is why we need to be more worried about public discourse/pronouncements.

It's One Hot Place Deep Down On The Floor Of Yellowstone Lake – About studies at Yellowstone Lake…the sensors and what they are revealing.

Shuttering fossil fuel power plants may cost less than expected -- ScienceDaily – Interesting…but I hope we’ll retire them all well before 2035 with the cost of renewals coming down so quickly. It will make economic sense to just do it!

Keeping Black Bears Wild And People Safe – This article is about black bears in Smokey Mountains National Park and the BearWise program more broadly. We do have Black Bears in Maryland and they occasionally show up in our area; there was one that showed up at our nearby elementary school a few years ago – caused a school lockdown until it wondered off.

Meet the Dipper, the Songbird That Swims – Evidently they are easier to spot in Colorado during the winter when they are concentrated long streams that remain unfrozen…but they are in the Rockies all year round…Dippers are elevation migrants (higher in the summer….lower in the winter). Maybe some post-pandemic trip we’ll look for them!

Gleanings of the Week Ending December 12, 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.

Massive Arecibo Telescope Collapses in Puerto Rico | Smart News | Smithsonian Magazine – Very sad. It was already being decommissioned which was wrenching….but then the collapse meant that even the instruments that might have been usable elsewhere were destroyed. My husband spent some time at Arecibo during his graduate school studies in the 1970s.

What do slight arm movements reveal about our breathing and health? -- ScienceDaily – Evidently it works best during sleep when there is not a lot of other movement other than breathing!

Hegra, an Ancient City in Saudi Arabia Untouched for Millennia, Makes Its Public Debut | Travel | Smithsonian Magazine – Undisturbed for 2,000 years…once an international trade hub although most of the surviving structures are tombs…a few hundred miles to the south of Petra

Proterra Sells Its 1,000th Electric Bus and New Electric School Buses In Virginia & Massachusetts – Electric buses are very appealing…I’ve always hated the sooty exhaust from diesel buses. Buses operate in situations where many people (and children) are in close proximity, so removing buses as a source of city and school pollution would be a good step forward.

Glyphosate may affect human gut microbiota -- ScienceDaily – A bioinformatics tool to predict if a microbe is sensitive to glyphosate – in the soil…in the digestive system of animals. The compound, widely used as a herbicide, biochemically targets plants but the same pathway is also in bacteria.

Opinion: The Biological Function of Dreams | The Scientist Magazine® - Learning more about sleep…and REM sleep in particular.

The mystery of Siberia’s exploding craters - BBC Future – Gas emission craters. Studies have revealed a 3-5 year life cycle: a mound forms…rising several meters, the gas underneath explodes. They tend to form in areas where there is a thick layer of ice over permafrost…with some areas of unfrozen ground surrounded by permafrost…and very deep deposits of gas and oil. The big challenge has been to identify the source of the gas that builds up – because after the explosion it is already gone.

Forest fires, cars, power plants join list of risk factors for Alzheimer's disease: Airborne pollution implicated in amyloid plaques, UCSF-led study shows -- ScienceDaily and Air pollution spikes linked to lower test scores for Salt Lake County third graders -- ScienceDaily – Studies that show the impact of air pollution on humans….other reasons to step up the pace of the shift away from fossil fuels. Thinking positively – actions to address climate change tend to improve air quality.

Mistletoe: A Natural and Human History – A plant associated with the season! And there are other species of mistletoe from around the world.

Top 25 birds of the week: December 2020! - Wild Bird Revolution – Beautiful birds….at the end of the gleanings list for this week.

Gleanings of the Week Ending December 5, 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.

Climate change presents new challenges for the drinking water supply -- ScienceDaily – Studying the Rappbode Reservoir in Germany and applying models….helping to predict what happens with warmer temperatures and increased drought…and what tweaks in reservoir management can mitigate.

The Lanterna of Genoa, the oldest lighthouse in Europe – The current Lighthouse of Genoa was built in 1543. The article includes some pictures of the technology used in the lighthouse from the 19th and 20th centuries.

Pollution and pandemics: A dangerous mix: Research finds that as one goes, so goes the other -- to a point -- ScienceDaily – Studying the relationship between along term ambient particles with a diameter of 2.5 micrometers or less and the spread of COVID-19….using air quality data and COVID-19 case across the country. There is a correlation – more pollution….higher COVID-19 transmission. Also: "We found black carbon acts as a kind of catalyst. When there is soot present, PM2.5 has more of an acute effect on lung health, and therefore on R0." This is an example of how air quality degradation has adverse health consequences.

Leila Jeffreys' Elegant Bird Portraits Show Feathery "High Society" and Photographer Tim Flach Captures Emotive Portraits of Fascinating Birds – I prefer birds in the wild…but sometimes portraits show the bird with more detail…certainly with less distraction. These two series were quite different but full photogenic birds.

Two centuries of Monarch butterflies show evolution of wing length -- ScienceDaily – Looking through museum collections and island populations of Monarchs, the researchers discovered how migration selects for longer, larger forewings….non-migrants have smaller wings! And they have determined that the effect is due to genetics rather than the rearing environment.

Photography In The National Parks: Birdy, Birdy In The Sky – Almost half the gleanings this week are about birds. I think this is my favorite. National Parks…great places for photography and birds add some action in the scene!

Top 25 birds of the week: Coastal birds – Some I’ve seen (particularly the ones in this group that were photographed in New Jersey). Others are totally new – like the Great Stone-curlew found in coastal areas of southern Asia…striking head pattern…and eye.

Tens of thousands of 12,000-year-old rock paintings found in Columbia – Found in an area previously inaccessible to researchers due to Columbia’s 50-year civil war. Made with red ocher.

Vitamin D regulates calcium in intestine differently than previously thought – Still new discoveries to be made about how our bodies work…how complex and interconnected the chemistry is….a system of systems.

Newly Discovered Underground Rivers Could Be Potential Solution for Hawai’i’s Drought – The potential for water wells off the coast of islands…supplementing fresh water available on the land to support the population living there.

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.

Iridescence - from archaeological glass to Art Nouveau – A little history of iridescent glass…how the effect is produced.

Photographer Captures Beauty of Starling Murmurations Across Europe – Awesome coordination of birds in flight. The starlings are not numerous enough in the US to create murmurations like this….but we did see flocks of tree swallows wintering in Florida that did.

New study reveals United States a top source of plastic pollution in coastal environments -- ScienceDaily and Plastic pollution is everywhere. Study reveals how it travels -- ScienceDaily – Plastic everywhere. We need to find a way to stop the waste.

Top 25 birds of the week: Plumage! - Wild Bird Revolution – Shots of color (I appreciated them more because it is a very cloudy day as I write this).

Into The Badlands Of El Morro and El Malpais National Monuments – Two places in New Mexico that I’ve visited several times…appreciated the pictures…reminder of how special these places are.

Which particulate air pollution poses the greatest health risk? -- ScienceDaily – Evidently the oxidative potential of particulate matter is key….wood combustion and metal emissions from brake and tire wear have higher oxidative potential, for example.

How to cut carbon out of your heating - BBC Future – A comparison of different types of heating…and other elements of carbon production related to heating where we live.

Wind & Solar Are Cheaper Than Everything, Lazard Reports – Great trend….now the market forces should push harder toward cleaner electrical generation.

The strange and surprising ways wild animals prepare for winter – The story starts out with bears but quickly moves on to animals not as well known for their winter preparations: moles, honey ants, chickadees, and snakes.

These Four-Foot Lizards Will Eat Anything—and They're Invading the Southeastern U.S. | Smart News | Smithsonian Magazine – The tegus, native to South America, and brought to the US as pets. They have roamed wild in southern Florida for a decade…and now are spotted around the southeastern US. It loves to eat eggs and thus is a threat to native species like quail, turkeys, alligators, and tortoises. The race is on to try to stop the invasion of this reptile.
