Apples, Walnuts… and Toast? A New Study Reveals the Flavors of Ancient Roman Wine - Georgian vintners still employ a rustic approach. Grapes are crushed by hand or foot, placed in egg-shaped vessels known as qvevri, and buried for up to six months. It’s a UNESCO-recognized tradition dating back 8,000 years and researchers believe can help reveal the sight and scent of ancient Roman wine.

Mexico is suing US gun-makers for arming its gangs − and a US court could award billions in damages - In January, a federal appeals court in Boston decided that the industry’s immunity shield, which so far has protected gun-makers from civil liability, does not apply to Mexico’s lawsuit. Mexico’s lawsuit alleges that U.S. gun-makers aided and abetted illegal weapons sales to gun traffickers in violation of federal law. According to the lawsuit, feeding demand for illegal weapons is central to the industry’s business model.

Climate change reversing gains in air quality across the U.S.: study - The study finds that climate change is increasing the prevalence of two of the air pollutants most harmful to human health: particulate matter, commonly referred to as PM2.5, and tropospheric ozone. Whereas pollutants from cars and factories could be targeted by regulations over the past few decades, climate-related deterioration in air quality is a much tougher problem to solve.

Avar Grave Offers Clues to 7th-Century Heavy Cavalry - Thought to be a complete set of lamellar armor, which was made from hundreds of small iron plates, was spread out over the warrior.

What Does a Solar Eclipse on Mars Look Like? New, Breathtaking Images, Caught by NASA’s Perseverance Rover, Give Us an Idea – Images of Phobos passing across the sun’s surface…back on February 8.

Benefits of heat pumps - Nationally, heat pumps would cut residential sector greenhouse gas emissions by 36%-64%!

How millennials could give the suburbs a much-needed makeover – The trend is to move to the suburbs and not feel like you need to go to the city to have a great dinner or to see a show or live music or the arts.

The far-reaching impacts of wildfire smoke – and how to protect yourself - One study found that a quarter of the US's PM2.5 pollution was caused by wildfire smoke. In western regions, as much as half was caused by smoke. If there is a wildfire nearby, the Centers for Disease Control and Prevention advise taking steps to limit your exposure where possible:

Choose a room to close off from outside air

Wear a tightly fitting respirator, if it is safe for you to do so

Keep track of fires nearby using services such as AirNow's fire and smoke map

Pay attention to health symptoms and seek medical care if needed

Ancient Lipstick Dating Back More Than Three Millennia Is Found in Iran – Analysis of the loose, dark purple fine powder revealed minerals (hematite, quartz, braunite, anglesite, and rare tiny crystals of galena) and vegetal fibers.

In Scotland, Renewable Power Has Outstripped Demand – A milestone for Scotland. The volume of electricity produced by renewables in Scotland was equal to 113 percent of demand in 2022. Fossil fuels still supply some electricity, helping to smooth over gaps in renewable power. Across the U.K., fossil fuel power is at its lowest level in nearly seven decades. Impressive.

Water-quality risks linked more to social factors than money - Low population density, high housing vacancy, disability, and race -- can have a stronger influence than median household income on whether a community's municipal water supply is more likely to have health-based water-quality violations. Many of the water-quality challenges are downstream of demographics, with many community water systems lacking the financial, managerial, and technical abilities to address the water-quality issues.

Step Inside Artist Dale Chihuly’s Stunning Seattle Studio, Filled with an Epic Antiques Collection and His Otherworldly Glass Forms – Interesting pictures.

Archaeological Tropes That Perpetuate Colonialism - We need to start with presence rather than absence. How did Indigenous communities survive, persist, and come to live at the places where they are today? How do Indigenous people conceptualize and engage with the places of their Ancestors? What stories do they share with their grandchildren?

The US is spending billions to reduce forest fire risks – we mapped the hot spots where treatment offers the biggest payoff for people and climate – Where forest-thinning and controlled burns could have the most impact in the western US….for reducing wild-fire caused carbon loss, protecting human communities, and both.

The gold jewelry made from old phones - "We're trying to encourage the idea that one person's waste is someone else's raw material." An article about what is happening at the UK Royal Mint re circuit boards from electronic waste.

Iron Age Child’s Shoe Found in Austria – Found in a salt mine in north-west Austria…a 2,000 year old shoe that once belonged to a child that lived or worked underground.

New Satellite Tracking Air Pollution Releases Its First Images – The TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument makes hourly measurements of pollutants over North America. NASA will share observations with agencies that provide weather forecasts in hopes of reducing exposure to pollutants such as ozone.

Fine Particulates Are Slowly Killing Us All - People who live in Delhi, the most polluted big city on the planet, are living 11.9 fewer years because of air pollution. People in Bangladesh, the world’s most polluted country, stand to lose 6.8 years of life compared to 3.6 months in the United States. Acknowledging the benefits to society from burning fossil fuels in the past is no reason to continue embracing them in the future. We have created a system that kills people. We have access to clean energy technologies that do not make negative health outcomes one of their embedded features.

New cause of Alzheimer's, vascular dementia - A form of cell death known as ferroptosis -- caused by a buildup of iron in cells -- destroys microglia cells, a type of cell involved in the brain's immune response, in cases of Alzheimer's and vascular dementia.

 Windows to the Past at Great Smoky Mountains National Park – History told through structures left behind (and maintained). Forever Places. A former resident said, ““…it was more like livin’ in the Garden of Eden than anything else I can think of.”

Dead trees around the world are shocking scientists – Hotter droughts are impacting forests more than anticipated. According to one 2019 study, global greening stopped more than 20 years ago, and vegetation has been declining since, all because of the drought-amplifying effects of warming. Forests are being forced into a transitional phase as they are impacted by the pressures of warmer temperatures, drought, fires, and insects. Perhaps the forests of the future will look very different from the forests that existed in the late 1900s.

Visiting the Grand Canyon will get more dangerous – A heat-related death was reported in July. As the summer days get hotter in the coming years, the risk will increase. I wonder if the peak visitation times at the National Park will shift to spring and fall rather than summer.

Study confirms link between concealed carry weapons and gun homicide rates – The study included 832 counties in the US from 2010 to 2018. "People aren't using concealed guns in public defensively to thwart potential homicides. Rather, having more guns in public through concealed carry appears to be more dangerous and leads to higher homicide numbers.”

This Arrowhead Was Made from a Meteorite 3,000 Years Ago – Found in Switzerland in the 1870s…. examined with X-ray tomography and gamma spectrometry recently. Based on the chemical composition, the researchers say it may have been made from a meteorite that fell in Estonia aroud 1500 BCE; a fragment must have reached Switzerland through trade.

Skin cancer screening guidelines can seem confusing – three skin cancer researchers explain when to consider getting checked - Since the early 1990s, the incidence of melanoma has risen dramatically in the U.S. This increase may be due in part to more emphasis on early detection. Despite this, the rate of death per capita from melanoma has remained unchanged over the last 40 years!

Over one million acres of tribal land submerged by dams in the US, research finds - Over the centuries, colonial settlers and the federal government have acquired over two billion acres from Native nations through various policies, including forced removal, allotment, and the reservation system.

Are You Ready to Have an Immersive Experience — With Your Home Yard? – I am gradually reducing the amount of my lawn…a little this first year in the house….more next year…and every year thereafter until there is very little – if any – grass to mow. Our homeowners’ association has ‘rules’ that I am currently following by simply extending flower beds around the house and making beds in the corners of the back yard. Hopefully by the time I want to turn more of the grassy areas to meadow, the project to create a meadow around the neighborhood ponds will be a success…and the ‘rules’ will change.

Rising methane could be a sign that Earth’s climate is part-way through a ‘termination-level transition’ - Since 2006, the amount of heat-trapping methane in Earth’s atmosphere has been rising fast and, unlike the rise in carbon dioxide (CO₂), methane’s recent increase seems to be driven by biological emissions, not the burning of fossil fuels. Natural variability…or the beginning of a great transition in Earth’s climate?

Wildfires and farming activities may be top sources of air pollution linked to increased risk, cases of dementia - Particulate matter air pollution from agriculture and wildfires might be more neurotoxic compared with other sources.

8 Great U.S. National Parks for Birding – Everglades, Hawai’i Volcanoes, Saguaro, Congaree, Channel Islands, Zion, Redwoods, and Yellowstone. I’ve been to 6 out of the 8!

We asked children how they experienced poverty. Here are 6 changed needed now – This was a study done in Australia. I wonder how applicable these findings are around the world.

The identical twins who discovered their secret sibling – An adoption agency that separated twins for adoption in the 1960s…and the researchers that were part of that process. Fast forward to 2022.

Heat wave reveals 17th-century English gardens – Longleat Gardens….a whisper of the past…from before the transition to natural parkland in the 18th century.

Is this the end of DC’s most-beloved hidden landmark? – I’ve never seen (or known about) the Capitol stones in Rock Creek Park but I’ve noticed the old columns dating from the same period that are in the National Arboretum. They are certainly a landmark!

Painted Bunting: The Fun of Local Bird Quests – I remember seeing some painted buntings at a Florida National Wildlife refuge and an indigo bunting under my bird feeder in Maryland. They are special birds!

Colorful solar panels could make the technology more attractive – Color is a lower priority than efficiency for me, but it could be very important in some applications.

A Beginner’s Guide to Butterfly Watching – I wish there were more butterflies to watch! It seems like every year there are fewer of them around.

Taming Tomorrow’s Wildfires – There is a wildfire burning somewhere in the US all the time recently. It’s important that we make changes to reduce their devastation.

New drug candidate fights off more than 300 drug-resistant bacteria – Antibiotics have been around for my whole life…but there is always the discomfort that more bacteria are becoming resistant…and there could come a time that the pre-antibiotic killers will beginning killing people again. I’m glad there are new drugs in development to take up the fight.

Olmec contortionist Reliefs Uncovered in Mexico – Artifacts from a civilization known for colossal head sculptures….hints of their culture.

How driverless cars will change our world – A little realism in the projections….rather than hype. Hopefully by the time I am old enough to no longer want to drive myself, driverless car options will be convenient and safe.

Ubiquitous food additive alters human microbiota and intestinal environment – The research was about carboxy methyl cellulose specifically. As I read the article, I wondered if this additive -that isn’t really about the nutritional value of the food at all – is one of the ways ultraprocessed foods are bad for us in unintended ways.

120 Volt Heat Pump Water Heaters Hit the Market and Make Gas Replacements Even Easier – This is good news. I’ll be watching as these come on the market…see how they are reviewed. I am assuming a line will quickly form with people wanting to replace their gas hot water heaters!

When Wildfire comes to Nature Conservancy Preserves – The preserves are managed with prescribed burns and forest thinning…and can provide examples of effective ways of managing wild areas against destruction by wildfire.

Children’s Teeth Reveal Breastfeeding Practices in Ancient Peru – A detailed study of the remains of 48 children from 2,500 years ago revealed that they were breastfed exclusively for the first 6 months of life and were weaned when they were about 2.6 years old. I wonder how many other ancient cultures have been studied this way.

Transparent Solar Windows: You Ain’t Seen Nothing Yet – If solar windows could be produced at reasonable cost….a lot of people would be motivated to replace their windows/power their house. There is a pleasing aesthetic to this type of solar power too.

Why Putting Solar Canopies on Parking Lots is a Smart Green Move – A great idea…hopefully it becomes the norm. The first one I noticed was at the Patuxent Research Refuge.

Top 25 birds of the week: Nectar Feeding Birds – Always worth looking at some bird pictures!

8 Fall Nature Experiences to Enjoy – There are so many things to enjoy in the outdoors during the fall – as the heat of summer fades away.

Exploring The Parks: 10 Historic Sites To Visit This Fall – More ideas for fall activities. I’ve been to all the sites they list that are on the east coast…but not necessarily in the fall.

NASA and USGS Launch Landsat 9 – The first Landsat was launched in July 1972 – the year my husband and I graduated from high school.

A new solid-state battery surprises the researchers who created it – Solid state electrolyte and an all-silicon anode – faster charge rates at room to low temperatures. There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!

Yale Climate Change Maps 2020 – Results from a spring 2020 poll about climate change.

Annual Flu Vaccine

It’s that time of year again – time to get the annual flu vaccine. This year it was very easy for me; I went to my grocery store pharmacy just as I did last year… right after they opened. There was no line, and their system already had all my information. I filled out a form on a clip board, provided an electronic signature, and got the shot.

I refrained from buying myself a treat like a piece of cake or a soft drink -went to the nearby thrift store instead. I found 2 pairs of ‘like new’ leggings that are easy additions to my fall wardrobe!

I am still planning another road trip to Texas in October so getting the flu shot in September means it will be fully effective by then. I am hopeful that the high rate of infection and hospitalization along my route will be reduced by then – and that hospitals will not be as overwhelmed as they are right now…just in case some accident occurs along the way.  

On the same day I got the flu shot – we had a very hazy day in Maryland and it was attributed to the California wildfires. Signs of climate change are everywhere. For me – getting the flu shot is an action to avoid a health issue at a time when the pandemic and climate change are straining the resources of our country to deal with those disasters – making it even more challenging to take the strategic actions to reduce and mitigate the climate change going forward.

Wind Energy Accounted for 42% of New US Power in 2020 – And solar was 38% of the new energy. And 8 east coast states have large offshore wind projects in the works in the years ahead. Hurray! It’s a good trend and it looks like the slope of the trend will keep increasing for wind and solar (decrease and go to 0 for new natural gas).

How people respond to wildfire smoke -  Another reason to slip on a mask.

Devastating Rain in Tennessee – A map of the change in soil moisture between August 20 and August 21. The floods on August 21 in Tennessee (area circled on the map) killed at least 22 people. I was surprised that there was an area of Illinois (to the north and a little west of the flash flood circle) where the soil moisture increased even more; perhaps that area floods frequently and the area is managed with flooding in mind.

New analysis reveals Vesuvius Victims’ diverse diets – From analysis of Herculaneum skeletons. Men got more of their protein from seafood. Women ate more meat grown on land, eggs and dairy products.

Eye provide peek at Alzheimer’s disease risk – Amyloid plaques can form in retinas of the eye. Does their presence there provide a visible biomarker for detecting Alzheimer’s risk?

Top 25 birds of the week: Wild Birds! – Bird photography…..challenging and beautiful subjects for our cameras.

Have you seen a weasel lately? – There is a suspicion that weasels are in the decline…but the data is circumstantial. These are not predators that have been widely studied. The post points to a role for citizen scientists!

Dispatches from a world aflame – Reviews of two books about the recent fires…and the relation to climate change.

Preemption of Green Cities in Red States – At a time when we need to get serious about addressing climate change – a drive by some states to keep local governments from taking any action. There is a cognitive dissonance between historically arguing for local control then usurping that control when the state government does not agree with it. I like local control but acknowledge that higher up the governance hierarchy could make sweeping changes easier. Perhaps some of these state governments will redeem themselves by quickly taking strong action toward climate change reduction and mitigation – soon. The top issue for me when I vote these days has become climate change!

Climate Change Is The Greatest Threat To Public Health, Top Medical Journals Warn – Another reason that actions to address climate change must be at the forefront of our thinking about the future. Medicine cannot make up for the injury we are making to ourselves and every living thing on the planet.

Most Memorable of 2020

Looking back on 2020 – there is so much that was different than prior years. There has not been a year of my life with so many significant types of upheaval: COVID-19 pandemic, environmental disasters (fires, hurricanes), racial strife, and strident politics. Today I am writing about the way this year was different for me as an individual with those upheavals as the broader situation.

Early year travel…then no travel. In prior years, I enjoyed travel throughout the year – being away from home a week or less at a time and daytrips. My original plan for 2020 was to spend a week of each month in Texas with my family. The early part of the year started out on that plan – a visit with family and a birding festival in Laredo, TX in late January and early February. We talked with an HHS person in the San Antonio airport; she was headed to the base where some of the first cruise ship passengers were arriving for their quarantine period. Once we got home, we hoped the virus was going to be limited to the few groups from cruise ships that were talked about in the news….and we started paying more attention. It quickly became apparent that telephone calls and Zoom meetings would have to take the place of the trips to Texas. We did some 2-3 hour outings for some outdoor time in the fall; we wore masks even outdoors and distanced from others; now that the infection rate is higher in our area and it’s often too cold to be outdoors for very long, we are not attempting more than walks around our neighborhood.

The Pandemic. By March, we had an inkling that COVID-19 was not going way and that there was more around in the community that anticipated. The grocery stories started having shortages of toilet paper and disinfecting products and hand sanitizer. Fortunately, we had an adequate supply of those to last until the stores had them again (although maybe not the brands we bought previously – what happened to Formula 409?). I went to an ‘over 65’ shopping hour at a local grocery in March and it was crowded enough that it scarred me into switching to grocery delivery for 2 months. I tried to keep 2-3 weeks of food in the house at all times. We bought over the counter medications that might help symptoms if we got sick. By the summer I was comfortable going to the grocery store again – masked and going at 6:30 AM every other week and, now, extending to every three weeks. We do curbside pickup at some local stores and restaurants. My husband has virtual and in-person appointments with his doctors, but we both delayed routine optometrist and dental checkups that started to be due; those appointments and my annual physical can wait until after we are vaccinated.

Cultural, environmental, and political drama. The pandemic would have made this a challenging year but with the cultural, environmental, and political drama happening as well – the news was overwhelmingly bad…traumatically bad. The trauma of seeing the murder of George Floyd by a policeman brought to the consciousness of the country that racial equality before the law is not something the US has achieved…and the varied response to the event showed us more about how deep the challenge runs in our culture…and highlighted other manifestations of inequality in our country. Because of our ‘stay at home’ strategy during the pandemic, we didn’t witness any unrest – but the news prompted some donations and solidified our votes in November. There were environmental disasters – fires in the west, hurricanes on the Gulf Coast; neither impacted us directly in Maryland, but it was very easy to be traumatized imaging how awful it must be for people trying to take precautions to not get COVID-19 but having to evacuate and then returning to find their home gone or damaged. The political drama – much of it seemingly intentionally done to sustain a level of chaos – continued through the end of the year; I became more angry as time went on that the leadership of the country – in a year of extreme national stress – seemed to be acting to increase the trauma.

Virtual birding festivals and conferences. I saved some positive things to write about for the last of this post….we all need something positive to sustain ourselves. My husband and I both enjoyed virtual birding festivals and conferences in 2020. They added variety to our weeks; we appreciated the work of the teams that made the transition to virtual because they took us away from our immediate environment (not quite as good as travel but the best we were going to do during the pandemic). We hope to be back to some in-person events in the second half of 2021. The ones we did virtually in 2020 were:

• May – Cape May Spring Festival (New Jersey)

• June – Mid-Atlantic Climate Change Education Conference

• July – Get into your sanctuary (NOAA)

• July and August – Sara Via Climate and Sustainability Webinars

• September – Yampa Valley Crane Festival (Colorado)

• September – Puget Sound Bird Fest (Washington)

• October – Cape May Fall Festival (New Jersey)

• October – Hawaii Island Festival of Birds

• November – Crane Fiesta (New Mexico)

• November – Patuxent River Conference Reflections

• December – Maryland Water Monitoring Conference

• December - AGU

At home. I spent more time at home this year than every before in my life (that I can remember…maybe I spent more time at home from birth to 4 years old). It’s been different but not hard. The house is well situated with forest to the back and a 30-year-old neighborhood street to the front with lots of trees as old as the houses; the views from the windows are all good – and there is wild life (birds (including an occasional wild turkey!), squirrels, deer, chipmunks, and racoons (seen only on the bird feeder cam in the wee hours of the morning)). Individuals and couples take walks…the neighborhood does not feel vacant or isolated. Inside - my husband and I have plenty of room to enjoy our individual projects/activities then be together for meals and shared activities…settling into a comfortable way of living in the house together and probably becoming more synchronized emotionally than we have since early in our marriage – simply because we are around each other more.

Conscious efforts to sustain healthy mental and physical health. As we’ve gotten older, we have become more intentional about our lifestyle – making sure we get enough exercise…eat healthy…assess our feeling and act to keep them positive. During this year – we have increased our focus. I had time to process the bounty of the CSA season (June-October) and am just now beginning to see that we have space in the freezer again. We eat well but keep our portion sizes reasonable; we haven’t gained weight…maybe we’ve lost a few pounds. We both try to get some outdoor time as frequently as we can – walks, yard work, reading on the deck, photography (stars/planets, sun, plants, animals, and snowflakes) etc. It was easier before it got cold. More of our exercise has shifted indoors at this point. We do things to brighten our mood – flowers, purchases to use for projects (mounted insects, clickers and magnifiers for cell phone photography), special pens, special food – things to make each day a little different.

Overall – at the end of 2020, I am feeling optimistic about 2021 and pleased that my husband and I have responded with resilience to the changes in our lives during the past year. We had ups and downs but on the whole managed to sustain ourselves and to enjoy parts of every day (for me it was easier when the television was off, and I wasn’t reading my news feeds).

Antibiotics found in some of the world's rivers exceed 'safe' levels, global study finds -- ScienceDaily and Hundreds of world's rivers contain dangerous levels of antibiotics – Same story from different news feeds. Antibiotics we take are not broken down in our bodies and are excreted. Wastewater treatment does not take them out of the water so the rivers are – over time – building up more antibiotics.

Ancient Fingerprints Show Men and Women Both Made Pottery in the American Southwest | Smart News | Smithsonian – The breadth of men’s finger print ridges are 9% wider than those of women…so pots that are made via pinching layers of coiled clay together using the thumb and forefinger (leaving fingerprints) can be analyzed to determine the gender of the person that made them. It turns out at Chaco Canyon that men and women made pottery…unlike the more modern tradition of the skill passing from grandmothers to mothers to younger women.

Route 66 Considered for National Historic Trail in The Park System – On a recent road trip, the Pacific, MO hotel we stayed in (west of St. Louis) was near Route 66. They had a map to continue the journey through Missouri on stretches of the old road. We needed to reach our destination quickly so stayed on I-44…but maybe sometime when we can take our time…we’ll take Route 66 where we can.

CITY SPROUTS: The Budding Movement to Integrate Garden-Based Learning in Public School Education | Children & Nature Network – A laudable goal…but it takes work. With teachers that already have a lot to do….organizing garden-based learning might be a tough addition to their job jar.

Most of the World’s Macadamias May Have Originated from a Single Australian Tree | Smart News | Smithsonian – The majority of macadamias are grown in Hawaii…so the lack of diversity within the trees in Hawaii leaves the crop open to species-level risk. This article talks about the research and search for wild plants in Australia to increase the diversity within the macadamia gene pool.

Seven US Species Invading Other Countries – Cool Green Science – We talk a lot about non-native species invading the US. Here are some that have gone the other way.

A Sea of Sagebrush Disappears, Making Way for Fire-Prone Cheatgrass: NPR – Nearly 75% of the acres burned by wildfires in the west are range lands rather the forest. And what burns is sage and cheatgrass. The problem is that cheatgrass, an invasive grass, grows faster than sage and is taking over land where sage once dominated…and cheatgrass is more flammable. Put that together with climate change and the look of the west is changing.

Megacities Like Paris and London Can Produce Their Own Clouds | Smart News | Smithsonian – The urban heat island phenomenon has been known for a long time. Now studies are looking at cloud cover over cities and it appears they are 10% cloudier than rural areas.

Still snarling after 40,000 years, a giant Pleistocene wolf discovered in Yakutia – Found in Siberia. The discovery was announced as the opening of a Woolly Mammoth exhibition in Tokyo organized by Yakutian and Japanese scientists. The same team also presented a well-preserved cave lion cub.

Six fingers per hand – People with 6 fingers on a hand (a form of polydactyly) can perform movements with one hand where people with 5 fingers would require 2 hands. The brain of polydactyly subjects controls the additional degrees of freedom the additional finger provides without sacrificing any other brain functions.
