Top 25 birds of the week: Bird Migration – I am missing the birds I see most during migration times in Maryland this year since I am in Texas.

Kestrel Cam: A Story from Egg to Falcon – Moving from the 25 pictures…to a detailed picture of a small falcon’s life beginning.

Climate change threatens one-third of global food production – We have lots of reasons to make changes…to stop mistreating our planet and let it recover. This is another one.

Saint Petersburg Keeps the Sea at Bay – A big project started in 1979 and operational in 2011…built to withstand a storm surge from the Baltic Sea of 5 meters.

Thirteenth-Century Angkor was home to more people modern Boston – I was surprised….recent studies have shown other ancient population centers were more populous that previously estimated too.

How cities will fossilize – From BBC Future. Thought provoking…using Shanghai Tower as an example to illustrate what could happen.

Flashy plants draw outsize share of scientists’ attention – ‘Aesthetic bias’ when it comes to choices for research (and probably extends beyond plants).

New Monarch butterfly breeding pattern inspires hope – Signs that the monarch butterflies in the western US might be adapting to changing climate. It’s good to see a little positive news about monarchs.

Egyptian Archaeologists Accidently Discovers 250 Ancient, Rock-Cut Tombs – Still new sites to study even in a country that has been intensively studied for many years. This time the tombs are not ‘royal’ – may provide more insight into how ordinary people lived in ancient Egypt.

Top 25 birds of the week -May 2021 – Starting out the gleanings list with bird photographs!

Why cats love to sit in boxes – even fake ones – All of our cats have liked sitting in boxes….it was fun to see some research showing that even the 2D shape is appealing to them!

An incomparable intellectual who fell through the cracks of history – A woman, of course. In this case it was Robert Boyle’s older sister, Katherine Jones, Lady Ranelagh.

Strange and surprising facts about Opossums – The only marsupial north of Mexico. Odd look and behavior.

Ancient pottery reveals the first evidence of honey hunting in prehistoric West Africa – Analysis of potsherds from Central Nigeria revealed that around 1/3 of the pots they came from were used for processing or storing beeswax! The pieces of pottery are from the 1st millennium BC.

Big Spring Lodge, Cabins Rehabilitation Lags at Ozark National Scenic Riverways – I hope the project now planned to start in the fall gets completed on time. The place would be a good vacation destination for us since my daughter lives in Missouri.

You are how you cook – Research on the cooking methods in different parts of China and the relationship to the type of grains utilized over time. The areas that boiled/steamed food tended to use millet over wheat or barley since the later two grains take longer to cook by that method.

Fighting dementia with play – A pilot study with a game consisting of a screen and floor panel with four fields that measure steps, weight displacement and balance….users attempt a sequence of movements with their feet requiring physical and mental skills. The pilot was promising. Perhaps these types of games will become one of the strategies to enable people to handle daily life longer.

Meet Benjamin Banneker, the black scientist who document brood x cicadas in the late 1700s – Benjamin Banneker Historical Park and Museum are close to where I live in Maryland. I’ve been there several times (posted about it in March 2015 and December 2018, but hadn’t realized that noting the periodic cicadas was one of his numerous observations.

You Can Now Explore the Louvre's Entire Collection Online | Smart News | Smithsonian Magazine – Next best thing to being there.

The radical coral rescue plan that paid off – Restoration after Hurricane Iris hit Belize in 2001.

Experimenting with Tucson Night Lights – Streetlights accounted for only 13% of the light visible after midnight….so we need to address other types of lighting to reduce the impact of outdoor lighting. Streetlights have been the easiest to address because they are a single source, and the local government has direct control over them.

1,200-year-old children’s hand prints found in Mexican cave – Made by Mayan children…perhaps made during coming of age ritual…in black handprints at first…then red.

Pileated Visitation – The joy of having a pileated woodpecker around long enough to photograph.

Forget Stonehenge: the first know massive monuments are much older – 6th millennium BC (7,000 years ago) structures on the Arabia Peninsula. Mustatils built as monuments by cattle herders.

Top 25 Birds of the Week: Seedeaters! – Starting out the gleanings list with bird photographs.

Mapping tree inequality: Why many people don’t benefit from tree cover – Trees are an effective way to reduce the heat island effect within cities (i.e. where there are fewer trees it is hotter). Lower income communities tend to have fewer trees…and thus are hotter. As there are more hot days, the impact is becoming greater. There is also a beauty to trees…each one is an island of nature in a sea of concrete and asphalt. Increasing trees in cities and towns is an investment in physical and mental health!

Roman temple at Egyptian Emerald Mine – In the eastern Egyptian desert. The researchers found 19 coins, incense burners, bronze and steatite figurines, bones, terracotta body parts, and amulets.

Return of Brood X Cicadas – This brood emerges in the area where I live in Maryland. I am not there to see it, but I hope my husband can photograph some emerging cicadas. There should be lots of opportunities!

Invasive Jumping Worms Have Spread to 15 States – This species is in the middle of the country. I haven’t seen any yet in Texas, but they are in the state and my daughter might have them in Missouri. Hopefully, there will be a method to control them soon or the landscape of that area of the country could change…they are a small organism with a big impact.

A Retreat to Catoctin – This park is close  (about an hour) from where I live in Maryland. I’ve been there many times….maybe not often enough.

Hopes and Weeping Trees: What’s up with the Yellow-bellied Sapsucker? – Neat rows of holes in tree trunks? There is a sapsucker around. Sometimes hummingbirds will come to get the sap dribbling out of the holes. I am always pleased to discover a tree that has been visited by a sapsucker; I noticed when I was at Mt. Pleasant this spring that the tree that was convenient to a hiking route for school field trips (pre-pandemic) has been cut down so I will hunt for another one to share with hikers.

Trove of 2,000-Year-Old Bronze Mirrors Found in Ancient Chinese Cemetery – 80 mirrors….ranging from 3-9 inches in diameter. There are other artifacts recovered from the same cemetery….maybe more stories to come as the excavations and analysis of finds continues.

Charting ice from above – The Icebird flights….flying low over ice and open water. What if feels like to be part of the crew.

National Parks Traveler Checklist: Padre Island National Sea Shore – My husband and I have been to parts of the Padre Island National Sea Shore for snippets of time. Our plan to visit in 2017 to see more of the park was cancelled after Hurricane Harvey…maybe we should add it to our post-pandemic travel plans!

Eating processed meat could increase dementia risk, researchers say -- ScienceDaily – A study with a large cohort (500,000 people) in the UK.

Photographer Travels Asia Capturing Beautiful Repeating Patterns – I liked the photographs for the repeating patterns but also how they capture the people and places. The photos capture the cultural landscape.

Stalking The Carnivorous Plants Of Big Thicket National Preserve – I can remember first reading about carnivorous plants in elementary school. I still find them fascinating.

How birds defend against brood parasites – I’ve already seen a pair of cowbirds at my feeder this spring; fortunately, they must have been migrating because I haven’t seen them again.

The Butterfly of Spring: Meet the Mourning Cloak – I haven’t seen one this spring…although I have in other years. All the ones I’ve seen in early spring are more battered that the one in the first picture!

Vitamin A for Nerve Cells – Another reason to eat those orange fruits and veggies. My favorites are carrots and butternut squash!

Washington’s Famed Tidal Basin and Cherry Trees Face Rising Waters – Planning initiated for how the area and its cherry trees could survive the rising waters in the coming decades. Some trees have already been lost.

Reflecting on your own capabilities boosts resilience -- ScienceDaily – Thinking about memories of successfully overcoming past challenges may help us cope with crisis situations we are facing in the present.

Great Lakes people among first coppersmiths | Science – The Old Copper Culture began earlier and faded earlier that previously thought…starting about 9,500 years ago and ending about 5,000 years ago. A climate shift might have caused the culture to shift from using copper for tools to adornment at the end of the period.

Waste from making purple corn chips yields a natural dye, supplements, kitty litter -- ScienceDaily – I like processes that dramatically reduce the amount of agricultural waste. I wonder if the purple kitty litter would stain carpet if it was tracked out of the litter box though.

Why cats won’t punish a stranger who harms you - BBC Future – Evidently cats do form emotional bonds with their humans…but they probably don’t pick up on human social relationships….not as domesticated as dogs.

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!

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.

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!

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.

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.

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.

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!

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!

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’!

Caligula's Gardens, Long Hidden Beneath Italian Apartment Building, to Go on View | Smart News | Smithsonian Magazine – A subterranean museum beneath the streets of Rome to open this spring.

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.

The Mark Twain House in Hartford, CT – 3D tour

Mount Vernon – George Washington’s house. 3D of the gardens and mansion

Lyndhurst – Several 3D views….including at Christmas and Halloween

Vizcaya Museum and Gardens – Florida. 3D with links to historic photos of the same area

Monticello – Thomas Jefferson’s house. 3D tour. There is also a Google Arts and Culture tour with video/photos.

Olana’s Historic Landscape Video Tour – Frederic  and Isabel Church home.

Val-Kill tour – Eleanor Roosevelt National Historic Site from Google Arts and Culture

Wilderstein – Online exhibit, aerial tour, and landscape tour. The house was the Suckley residence for 3 generations from 1852 to 1991.

Ice sheet uncertainties could mean sea level will rise more than predicted -- ScienceDaily – There are warning signs that the current models aren’t accurately predicting ice sheet dynamics.

How mail-order frogs could save Colombia's amphibians - BBC Future – Carefully breeding frogs to keep them from going extinct in the wild.

Meet Amanda Gorman, the U.S.' Youngest Inaugural Poet | Smart News | Smithsonian Magazine – Leading with eloquence and hope for the future….pushing us to strive for a country that is a ‘more perfect union.’

House Agrees Saguaro National Park Should Grow By 1,200 Acres – Hope this happens…when my daughter was in Tucson we enjoyed this park many times.

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.

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.

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.
