Watch a Deep-Sea Squid Carry Hundreds of Pearl-Like Eggs – A video from the Monterey Bay Aquarium.

It’s a trap: managing cowbirds to save songbirds – The strategy of trapping cowbirds (a brood parasite) to help endangered songbirds along the Santa Clara River in Southern California has evolved to reduce harming other species and cost less.

Electric vehicle buyers want rebates, not tax credits – Of course….immediate rebates rather than waiting for months to get a tax credit are much more appealing.

Urban waterways: discovering the hidden beauty of a Jersey River – River restoration across the country…with the Cooper River story in more detail.

Universal influenza B vaccine induces broad, sustained protection – A new kind of vaccine….using nanoparticles. Perhaps this new technology will lead to an effective universal flu vaccine.

The sustainable cities made of mud – A little construction/architectural history….that could be applied more often.

10 Weird Australian Marsupials You’ve Never Heard Of – So many unusual animals…Australia has more than just kangaroos and koalas!

Cancer probably killed world’s first known pregnant Egyptian mummy – 2,000 years ago a young woman died…and was mummified. The Warsaw Mummy Project has determined that she was pregnant – the fetus was ‘pickled’ in the highly acidic and low oxygen environment of the mummified womb – and the woman probably died of nasopharyngeal cancer.

More Electricity from Wind and Solar than Nuclear for 1st time in USA – Hurray! Wind and solar accounted for over 25% of the nation’s electricity in the first 4 months of 2022!

Loss of male sex chromosome leads to earlier death for men – What? Y chromosome loss happens in 40% (estimated) of 70-year-old men. The loss occurs primarily in cells with rapid turnover, such as blood cells. And it might lead to heart muscle scaring…and then heart failure.

Under Water and Under Pressure – 100 national parks are coastal…and are already taking action to mitigate sea level rise.

Where do ‘Hawaiian box jellies’ come from? – Evidently the box jellies appear close to shore like clockwork 8-10 days after full moon. This research reveal that the jellies are spawning during that time…and where they are when they not close to shore. This is important for providing better information to ocean swimmers and beach goers…trying to avoid stings. Another benefit…learning to keep the food web balanced to control box jelly numbers in Hawaii and other tropical localities.

Stirring up a mid-Atlantic bloom – Lots of nutrients flowing into the water from the coastal watersheds during spring rainstorms.

Vancouver requires gas stations & parking lots without EV chargers to pay $10,000 per year – Interesting idea…hope it increases the number of chargers and the trend to EVs!

Photography In The National Parks: More Favorite Places For Photography - We’re not going to be traveling to any of the western parks near term….so I enjoyed them through these photographs: Crater Lake, Redwood, Yosemite, Great Basin, and Lewis and Clark (Washington state portion).

Maya tooth treatments may have prevented infection – In the Mayan world - holes were drilled to attach stones to teeth; an analysis of the sealant used for 8 teeth from across the Maya empire (AD 200-900) revealed that most sealants included ingredients from pine trees that have been shown to fight the bacteria that cause tooth decay.

Top 25 birds of the week: Forest Birds – I always like bird pictures….

Scientists recreate Cleopatra’s favorite perfume – Recreating Mendesian perfume…the result so far has been a strong, spicy, faintly musty scent that tended to linger longer than modern fragrances…with ingredients like desert date oil, myrrh, cinnamon, and pine resin.

Grand Canyon of Texas – I remember (tent) camping in Palo Duro Canyon in the 1970s on the way to Colorado…being very hot and worried that our tent was too close to a red ant bed! At the time, I didn’t realize that it is the second largest canyon in the US (behind Arizona’s Grand Canyon).

Why humans get less sleep than other primates – A different type of sleep research…teasing out the differences in sleep of humans and other primates….and between non-industrial human populations and industrial human populations. It turns out that in the human populations…the hours of sleep are about the same but the perception of getting enough sleep is higher in the non-industrial populations than the industrial ones!

A Watershed Moment: Key Findings About Potential Drinking Water Contamination – The sources of contamination are varied….but the list of primary sources is relatively short.

Better residents’ health after switch to electric buses – A study from Sweden. Improved health is a benefit of electrification of transportation!

Should people get rid of their yards? – Somewhat depressing conclusion: “Most people would rather make an aesthetic choice with their lawns than an environmental one.” My plan is not to eliminate the yard in my new house but to minimize it over time with the addition of bushes along the fence and extending beds around trees and around the house.

We talk the fastest growing green jobs with LinkedIn Sr. Editor – The “job vs the environment” is changing. The “green economy’s ability to expand job opportunities is too significant to ignore.” This growth in green jobs is like the 1970s for computer related jobs – a lot of new types of jobs and many of them will extend for the duration of a career starting now.

Discover the Microscopic Wonders of Olympus’ 2021 Image of the Year Awards – Taken with light microscopes…lots of finesse preparing the specimens.

Known to be toxic for a century, lead still poisons thousands of Midwestern kids – Two things I learned from this article about the state I am moving to: Missouri is one of the four states in the Midwest that is struggling to alleviate lead poisoning in children…and it is the number one producer of lead in the US. Hope they are making progress.

Top 25 birds of the week: terrestrial birds – Always enjoy the bird photographs! This group includes a roadrunner….a bird I always associate with Texas but the photograph was taken in California!

Tests indicate bronze age daggers had a practical purpose – Evidently the daggers were thought to be ceremonial objects prior to this analysis.

Should we be eating three meals a day? – The number of meals may not be as important as consistency….and giving the body a long enough ‘fast’ time to rest.

The Great Barrier Reef through Time – Landsat Images used to illustrate recent research on the growth of the reefs as the ocean changes. Evidently the reef has been more resilient to past sea-level and temperature fluctuations than previously thought….but increased sediment input has been a bigger problem.

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.

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

Study recommends six steps to improve our water quality – The study focused on nitrogen pollution.

The cells that give you super-immunity – Memory B cells were first discovered in the 1960s….but there is still a lot we are learning about them as we analyze the data from the COVID-19 pandemic.

Chicken Frenzy: A State Awash in Hog Farms Faces a Poultry Boom – Ugh! Hope North Carolina can figure out how to keep their groundwater and waterways from being polluted. It’s a beautiful state and it saddens me that the intensive hog and poultry production has not developed technology to be friendly to their immediate environment….or any place that is down stream from where they are located.

What’s the Weirdest Animal Courtship? Here Are 4 Candidates – A post that came out on Valentine’s Day.

Heart-disease risk soars after COVID – even with a mild case – Heart disease was already one of the chronic conditions common for a lot of people in later life… now with COVID, the numbers of people are going to increase and the age demographics are skewing younger.

Enhanced forensic test confirms Neolithic fisherman died by drowning – A skeleton from a 5,000-year-old mass grave on the coast of Northern Chile was analyzed with methods used for more recent bones to determine if a person drowned in salt water….and the method worked!

The mysteries of the Ponderosa Pine – The complex relationships between the health of pine forests and: birds, low-severity fire, squirrels, mushrooms, and carbon storage. Forests are complex!

The science of healthy baby sleep - A little history…and the bottom line: there is NOT just one correct approach to how infants should sleep.

Feeling dizzy when you stand up? Simple muscle techniques can effectively manage symptoms of initial orthostatic hypotension – There might be more validation that needs to be done across a wider demographic range…..hope this happens and if it works for a wide range of people so that doctors can immediately start encouraging their patients that have initial orthostatic hypertension (IOH) to use the simple moves before and immediately after they stand up.

Do you know the world weirdest wild pigs? – The post includes 5 of the 18 wild pig species. The only one in North America is the Africa Red River Hog – one was caught in a trap set for feral hog control in Texas (2019); there are evidently Texas game ranches advertising ‘hunts’ for red river hogs which indicates they have been intentionally imported and there has been at least one escapee from one of those ranches! Is there a free-ranging population of African River Hogs reproducing in the wilds of Texas?

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

Why the Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

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.

Spruce Tree House – extreme rockfall management – It’s been decades since I visited Mesa Verde, but I’m still drawn to any articles about it. This one was a reminder of the fragility of the place from a geologic perspective.

4 of the biggest archeological advancements of 2021 – including one ‘game changer’ – I always browse these end-of-year summaries…catch up on any big things that I somehow missed when they were originally in my news feeds.

No more annual flu shot? New target for universal influenza vaccine – Wouldn’t it be nice if this could happen? Even if they did develop a vaccine effective against all strains of influenza…would we still have to get boosters (i.e. would our immunity fade over time)?

With omicron, you need a mask that means business – I’ve been wearing KF-94 masks since February. My Christmas present from daughter was some patterned ones…although I still have a good supply of the black (the Ninja look) ones. I wear one anytime I am indoors (and not at home) and if I am outdoors with a lot of people around. Now that it’s cold, I wear them for warmth too; it’s surprising how much the mask keeps the nose and face comfortably warm….and the mask seals well enough that my glasses don’t fog!

Climate Clues from the Past Prompt a New Look at History – Some examples of the outsized role of climate in human affairs….and the interdisciplinary contributions to papers on the topic.

As Wetland Habitats Disappear, Dragonflies and Damselflies Are Threatened with Extinction – Maybe we need to start thinking about having wetland/ponds in our gardens as well as pollinator gardens…reduce the ‘lawn’ part of the area around our houses.

Forest Keepers: The National Park System is an essential laboratory—and also a battleground—in the management of invasive pests – The invasive pest pictured at the top of this article is woolly adelgid…something a learned to recognize in our area of Maryland…that has killed most of the hemlocks. Some of the trees growing in parks were saved with aggressive treatment, but the ones in the forest behind our house are gone.

New smart-roof coating enables year-round energy savings – A technology that changed the reflection/absorption properties of the roof based on temperature would be another step toward increasing the energy efficiency of buildings….reducing the heat island that plagues cities.

Study shows critical need to reduce use of road salt in winter – This has been a topic in several water quality sessions I’ve attended overthe past few years in Maryland. I have noticed the spraying of brine prior to storm events in our area so maybe some jurisdictions are already following the suggestions in this article.

Inside Idaho’s Campaign to Include Indigenous History in Its Highway Markers – Good idea; history of the US is more than European colonization. This article also prompted me to wonder if there are web sites that document the location and text of highway markers. I did some web searches and found several at the state level…and a general one: https://www.hmdb.org/

In the Middle Patuxent River – 1

Another morning in a local river last week – the Middle Patuxent near King’s Contrivance. There are pathways from the neighborhood streets nearby to connect to the Kings Contrivance Loop that are lined with the big trees of the easement along the river.

A part of the Loop trail parallels the river for a short distance and there is a root supported path down to the river in one spot. The river was more silt than cobbles…more big trees had fallen in from the bank since the last time I was there (pre-pandemic). Still – being in the river is a wonderful outdoor experience every time. There are gentle sounds of the water moving…trees ruffled by little breezes. It was a cloudy day but enough light filtered through the canopy to make patterns on the surface of the water.

I took some pictures of leaves that had fallen recently and were plastered to the sandy beach near the water. Soon there will be a lot more.

And then the students arrived and it was a flurry of activity while we collected and identified macroinvertebrates…decided that, based on our sample, the water quality was poor but not dead. There were macroinvertebrates in good numbers…but skewed toward species that are tolerant to pollution. Some of the students were surprised at how easy it was to step in water just over the height of their boots! They good naturedly made their way to shore, took boots off one at a time to pour out the water.

And then the time was up - the students headed back to their buses and the river was quiet again. I climbed back up the bank on root ‘steps’….glad that the abundant green on both sides of steep bank was NOT poison ivy!

Near the Little Patuxent River

On a recent morning – I headed out to the stream that flows under Broken Land Parkway from Lake Elkhorn just before it joins the Little Patuxent River for a volunteer gig – guiding a stream survey done by high school students. Near the bridge that crosses the stream on the Patuxent Branch Trail, there was muddy trail (poison ivy on each side…glad I had on long pants and high boots) to allow access down to stream. We set up our gear around three tables. There was not much dry area to set them up but the water was shallow. A partner and I guided 10 students to collect and ID macroinvertebrates from one of the tables while other volunteers did the same at two others. We had about 45 minutes….and then we got another group of 10 to do it again.

I took some pictures before and after the students arrived. The steam has a lot of vegetation on the banks but the stream has been eroded  - with some trees toppling over from being undercut by rapidly moving water. It is in an area where there is a lot of impervious surface. When it rains – the water rushes down to the stream where it carries away anything in the eroded channel; there is no connection to a flood plain that to slow down the water. It doesn’t take long for it to run off further downstream because we are in the Pediment rather than the Coastal Plain (i.e. there is always an incline for the water to follow).

The water quality was ‘very poor’ based on the types of macroinvertebrates that we found…however – we found quite a few of the types we found. The stream is not dead. Life holds on tight in this suburban stream.

Top 25 birds of the week – June 2021! – The first picture startled me – a bird with a turquoise beak!

Beach Safety Tips: How To Avoid Being Bitten or Stung This Summer – I’m don’t go to the beach frequently…and then am usually more interested in shells and ghost crabs than being in the water! Still – the safety tips were interesting.

Concrete: The material that defines our age – With the collapse of the reinforced concrete building in Florida….this story seemed particularly timely.

Edible Cholera vaccine made of powdered rice proves safe in phase 1 human trials, study suggests – Reminded me of distribution ease of the polio vaccine sugar cubes back in the 1960s. In this case the special rice is powdered and sealed in aluminum packets that are then mixed with 1/3 cup liquid and drunk. Hopefully, the subsequent phases of the trials will be successful…it could save a lot of lives.

Yellowstone and Warming: An Iconic Park Faces Startling Changes – A few degrees makes a big difference….in National Parks too.

Scientists Find Toxic ‘Forever Chemicals’ in More Than 100 Popular Makeup Products – I hope manufacturers of makeup will check their ingredients more carefully….make their products PFAS-free.

Canada is right to classify single-use plastics as toxic – I hope the US takes similar action. Industry should get on board with this idea and be innovative rather than taking legal action.  There is no ‘responsible plastic use’ for single use plastic. We consumers are too accepting that single use plastics are inevitable. It’s pretty easy for us to avoid singe use plastic bags, straws, stirring sticks, six-pack rings, plasticware….the one that is challenging for me is the hard-to-recycle food containers because of the lack of options in grocery stores and restaurant takeout.

Move Over Bald Eagle: Meet 12 of the World’s Coolest National Birds – Some are flashy…some are majestic….a little history of how they were selected aa representatives for their country.

Losing Ladybugs – Native and non-native ladybugs….you are more likely to see the non-natives now.

Florida’s Manatees Are Dying at an Alarming Rate – Starving because water pollution (nutrient runoff causing algal blooms) smothers seagrass. More than 10% of the manatee population of Florida has died so far in 2021. Very sad for other aquatic species that need the same habitat … and people too.

Water treatment: Removing hormones with sunlight -- ScienceDaily – Research to find and remove micropollutants. Micropollutants have become more concerning over the past few years as research has shown the potential for health impacts.

Which processed foods are better than natural? - BBC Future – Processed foods are not all unhealthy. Some are better than fresh (for example, canned tomatoes, pasteurized milk). But watch out for ultra-processed foods – ones derived from foods and additives; they can alter gut bacteria, cause inflammation….and many people have a tendence to overeat ultra-processed food.

Top 25 birds of the week: endemic birds – Birds found only in a small area of the world…and no where else. My favorite is the Bee Hummingbird – smallest hummingbird in the world and only found in the Cuban archipelago.

Dietary cocoa improves health of obese mice; likely has implications for humans -- ScienceDaily – Hmmm…maybe my 2 squares of dark chocolate for 1st breakfast is not a bad thing at all…even though I am not obese.

Chipmunk Quest – We have had chipmunks around our house periodically. They are fun to watch. They seem to taunt our cat through the window!

Why Bald Eagle Populations Soared in the Last Decade | Smart News | Smithsonian Magazine – A good news story of species recovery.

Europe’s Drive to Slash Plastic Waste Moves into High Gear – Hope similar efforts are made in the US. As an individual, it is hard to avoid single-use plastic although I have made an effort to avoid plastic shopping bags and buy products in paper/metal rather than plastic when that is an alternative.

Move Over, Cicadas: 5 Other Great North American Wildlife Hatchings (and Emergences) – The Brood X cicada emergence is beginning to wane in our area….it was interesting to think about other emergence type events. Maybe one of the events mentioned in this article will motivate a road trip in the next year or so.

Tropical species are moving northward in U.S. as winters warm: Insects, reptiles, fish and plants migrating north as winter freezes in South become less frequent -- ScienceDaily – Shifts already observable…others projected.

Report exposes power gap at US universities – Only one in ten top-earning faculty members is a woman.

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.

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.

Taking the measure of sea level rise - ocean altimetry, land motion, ice height, gravimetry – NASA missions that measure some aspect of sea level rise…there is a lot to work to measure and analyze – to better understand that is happening.

Health Care Facilities Maintain Indoor Air Quality Through Smoke and Wildfires | U.S. Climate Resilience Toolkit – Some of the HEPA filters purchased for the pandemic were available and were used to keep hospitals operational in areas where the outside air was smokey. Are we going to need this type of filters in our homes as well – for air quality more than the pandemic?

Top 25 birds of the week: Seabirds – Beautiful birds…from all around the world.

From Palmyra to the Pacific: Realigning a Rainforest – Cool Green Science – An atoll 1000 miles southeast of Hawaii…marred by human intervention…now owned by The Nature Conservancy…inspiring the creation of the Pacific Remote Islands Marine National Monument in 2008. Restoration is ongoing to maximize Palmyra’s resilience to climate change: eradicating black rats, realigning native rainforest (not restoring because what was there originally is unknown), and reintroducing native bird species.

Red maples doing better in the city -- ScienceDaily – Hurray for red maples. The study was done in Philadelphia which is a couple of hours from where I live….and I have a health red maple in my back yard!

Deformed Beaks: What We Know About An Alarming Bird Disease  - Avian Keratin Disorder (AKD) which might be caused by a poecivirus. The birds in the article are from Alaska but some are species we have hear in Maryland too. Hopefully, this is not a disease that will become widespread.

Top US States for Percentage of Electricity from Solar – Even states that aren’t normally viewed as ‘high sun’ are near the top of the list! This chart will probably change a lot over the next few years as more and more utility companies and individuals transition to renewables. Government can help but it is quickly becoming the more cost-effective path forward…market forces will drive the transition.

Scientists Discover New Human Salivary Glands | The Scientist Magazine® - Tubarial glands…what a surprise that they haven’t been discovered previously!

Floating gardens: More than just a pretty place -- ScienceDaily – It is a small experiment…but there was measurable nitrate reduction by the garden….maybe it is something that could be scaled to reduce accumulation of nitrate (from agricultural and yard runoff) that causes algal blooms.

Largest Arctic Expedition Ever Comes to a Close | Smart News | Smithsonian Magazine – The Polarstern, a German research vessel, is back in port after spending a year drifting with the ice floe across the Arctic. It will take 2 years to fully process all the data collected but the initial assessment of the Arctic environment is summarized as grim: ice gone in places it should be meters thick.

Top 25 birds of the week: October 2020 – Starting out the weekly gleanings with birds.

Linking calorie restriction, body temperature and healthspan -- ScienceDaily – Interesting research. I went off on a tangent thinking about “up to half of what we eat every day is turned into energy simply to maintain our core body temperature.” Many people in the developed world spend the majority of time in temperature-controlled buildings or homes…and that means we probably expend a lot less calories warming or cooling ourselves than we did prior to efficient heating and cooling systems. Just one more way we are changing our environment in a way that will tweak our future evolution.

The super-adaptable chimps that can withstand climate change - BBC Future – I didn’t realize how many different habitats chimpanzees are found in…and that the ones that live in environments with greater seasonal change have more varied behaviors to respond to those changes than chimps that live in an environment that doesn’t change much.

Environmental Education Goes Virtual: Creating Meaningful Learning Opportunities at Home: The National Wildlife Federation Blog – So many good online resources…they’ve been developed over years but are probably getting a lot more use during this pandemic year.

It's Tarantula Season At Bandelier National Monument – I’ve not been to Bandelier during tarantula season! The last time I was there was in March 2005 and that was before I started taking a lot of pictures….this article reminded me that I want to go again. Maybe we’ll plan to go in the fall and be on the look out for the male tarantulas trying to find a mate. Here are a couple of pictures my husband took when we visited in 1980!

Are we living at the 'hinge of history'? - BBC Future – It’s difficult not to look at current trends and think the future will be a dystopian one with or without seeing this as a ‘hinge.’ The last paragraph was the best of the article: “So, while we do not know if our time will be the most influential or not, we can say with more certainty that we have increasing power to shape the lives and well-being of billions of people living tomorrow – for better and for worse. It will be for future historians to judge how wisely we used that influence.”

Why is America Running out of water? – Shortages are not everywhere…but there are places in the US that are already problematic…and there are a lot of people living in those areas.

Raptor Rescue: When Bird Injuries Warrant Rehab – This article was a good summary of things I’ve heard about before re injured birds.

Unusual climate conditions influenced WWI mortality and subsequent influenza pandemic -- ScienceDaily – Something new about the 1918 flu…torrential rains and unusually cold temperatures kept Mallard ducks from their normal migration…and thus spread the virus more broadly in the battlefields of the Western Front.

What 'net-zero carbon' really means for cities - BBC Future – Using London as an example: no/fewer cars and all transport EV, less concrete…more timber, buildings reused/retrofit, green roofs and walls, renewable energy, reduced waste through recycling and energy production, urban farms. It’s technology that exists now…and already is being applied…ramped up, of course.

Top 25 birds of the week: Diet and Birds in Groups - Wild Bird Revolution – Catching up with collections of bird photographs. Some species appear in both sets!

Older adults share fewer memories as they age -- ScienceDaily – As I read about this study – I remembered that my grandmother often seemed surprised when I asked her about her memories of school…of what she remembered from her life before marriage…when my father was born, etc. She even asked why I was interested. Once she was reassured that I was…and that I wanted to take some notes…she was more than willing to share her memories which were often quite vivid well into her 90s.

Breathtaking Photos of Farmers Harvesting Lilies from the Mekong Delta – How beautiful! Near us – this type of water lily harvesting was done at Kenilworth Gardens in the first part of the 1900s.

Death and Drama Among the Cicada Killers – I remember collecting two cicada killers for my insect collection during the summer before my sophomore year in high school. I saw one go into a hole and put a jar over the hole….and two cicada killers came up into the jar. This article helped me understand what I found. First – they both had stingers, so they were females. Second – one of them had dug the hole…and the other was trying to covertly lay her eggs on the cicada the other had brought to the hole!

The hidden risks of cooking your food - BBC Future – There are benefits too….

Putting Communities at the Center of Freshwater Conservation – Cool Green Science – This type of thinking needs to be more prevalent re US freshwater resources as well. There are some parts of the country that are a drought away from severe water shortage just for the human population (particularly if water for agriculture is included as that allocated for humans)…nothing left for wildlife or riparian landscapes.

Tongue microbes provide window to heart health -- ScienceDaily – Maybe a new tool for detecting and treating heart failure.

The astonishing vision and focus of Namibia’s nomads - BBC Future – Detecting visual and attention changes caused by modern life.

Is It Possible to Shower Too Much? - The Atlantic – There is hygiene critical to health….and going beyond that might be harmful.

Climate Change Tied to Increased Pregnancy Risks, Analysis Finds - Yale E360 – Air pollution and heat exposure are linked with negative pregnancy outcomes in the US…..and both of are increasing in the US. And the impact of air pollution and excessive heat is problematic for babies too.

Unique Activities for Yesterday:

2 fawns. For the past few days, we’ve had two fawns in the back yard in the morning – after my usual early morning hour on the deck. Sometimes the doe is close to them…one morning she stayed back in the forest while the fawns wondered around. One day the flies were bothering them; they are particularly noticeable on the doe. It’s not unusual for deer to have twins. It seems like it is the norm for the ones we see in our backyard during the past few summers.

Fashion as Design office hours. The Fashion as Design Coursera course from last April provided two Zoom based sessions this week. Both provided references that update the course relative to the current crises in the US. I managed to open many of the links posted to the chat during the office hours and am passing some of them along:

• Design Emergency – Instagram Live sessions that explore design’s role in the COVID-19 crisis. A collaboration between Paola Antonelli (design curator at MoMA) and Alice Rawsthorn (design critic). I am going to work my way through the videos on this site.

• That Time When We All Fell Back in Love with Nature | British Vogue – From the August issue of British Vogue.

• Kerby Jean-Raymond on Defunding the Police: “Anything else isn’t worth talking about” – Jean-Raymond is a designer that was one of the people featured in the course videos. Recently he drafted a list of actionable demands that the Council of Fashion Designers of America (CFDA) members and its associated companies could be held accountable for. He was interviewed for the latest  edition of Frontpage. His bottom line: “Now all you can do is pick a side — and if you don’t pick a side, that means you picked a side.”

• The Tuxedo Redefined – Virtual Exhibition from earlier this year curated by NYU Costume Studies Graduate Students.

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

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

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

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

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

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

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

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

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

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