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.

In search of the Old Ones: Where to find the world's longest-lived trees – 25-30 woody plants can, without human assistance, produce specimens that reach the age of 1,000 years or older. Of those, only about 10 can reach 2,000 years and those are all conifers. 3 can produce trimillenials and 1 can produce quadrilmillenials. The longest-lived trees of eastern North America, bald cypress, grow in swamps and blackwater rivers. The eldest occur in backwater sections of North Carolina's Black River, just miles from industrial hog farms and fields cleared long ago for tobacco….these bald cypresses reach ages of 2,600+ years. Conifers achieve maximum longevity when conditions are cold and dry, or hot and dry, or steep and exposed, or high altitude, or nutrient poor. In the case of Great Basin bristlecone pine, the longest-living plant on the planet, it is all of the above, with some of these plants reaching up to 4,900 years old.

Conservation of Monumental Mexica Snake Sculpture Continues - Discovered last year in the heart of Mexico City at the site of the Templo Mayor, the main temple in the Mexica city of Tenochtitlan. The 500-year-old sculpture, which measures about six feet long and three feet tall, was painted with yellow, blue, red, black, and white colors made from minerals and plants employed by the Mexica on cult images and temples.

Fungal infection in the brain produces changes like those seen in Alzheimer's disease - When the fungus Candida albicans enters the brain, the body’s response generates amyloid beta (Ab)-like peptides, toxic protein fragments from the amyloid precursor protein that is considered to be at the center of the development of Alzheimer's disease.

Wildlife Photographer of the Year winners show the beauty — and precarity — of nature – My favorite is the Plants and Fungus winner (Last Breathe of Autumn) taken on Mount Olympus.

Scientists says identifying some foods as addictive could shift attitudes, stimulate research - Most foods that we think of as natural, or minimally processed, provide energy in the form of carbohydrate or fat -- but not both. Many ultra-processed foods have higher levels of both. That combination has a different effect on the brain. In a review of 281 studies from 36 different countries, researchers found ultra-processed food addiction is estimated to occur in 14 percent of adults and 12 percent of children. Viewing some foods as addictive could lead to novel approaches in the realm of social justice, clinical care, and public policy.

Flood Resilience Through Green Infrastructure - Green spaces don’t just mitigate flooding. They beautify the urban landscape and improve residents’ mental health. They filter out microplastics and other pollutants, keeping them from reaching sensitive water bodies like rivers. And when the weather is hot, they cool neighborhoods, because plants ‘sweat.’

15th-Century Theater Floorboards Uncovered in Norfolk - A combination of tree-ring dating and study of the building's construction dated the floorboards to between 1417 and 1430. This suggests that William Shakespeare may have performed on the boards!

Second report on the status of global water resources published - Large parts of the world experienced drier conditions in 2022 than those recorded on average for the equivalent periods over the last 30 years. The report results from the expertise provided by 11 international modeling groups to extrapolate from the data/statistics available. There is a particular lack of data on the situation regarding groundwater.  

More Mammals Can Glow in the Dark Than Previously Thought - By examining museum specimens, researchers documented the glowing property across 125 mammal species. Humans, for example, have fluorescent teeth, like all mammals do. In 1911, researchers reported fluorescence in European rabbits, marking the first documented case of the glowing ability in a non-human mammal.

21 species have been declared extinct, the U.S. Fish and Wildlife Service says – 10 birds, a bat, 2 fish and 8 freshwater mussels. There are now 650 species that have gone extinct in the U.S., according to the Center for Biological Diversity, which says factors such as climate change, pollution and invasive species contribute to species loss.

Teotihuacan in 1906

/

Leopoldo Batres, a pioneer of the archaeology of Mexico, published a picture book of the Teotihuacan site as it was in 1906…during early excavations. His reconstruction of the Pyramid of the Sun was evidently flawed but the book is still worth browsing to understand why the place was never ‘lost’ once it was created; the structures are large and dominate the scene even before excavation.

Teotihuacan : memoria que presenta Leopoldo Batres ... año de 1906

Looking at the book reminded me of a trip to Mexico City with my parents in 1966; one of the places we visited was Teotihuacan and I remember it vividly; it was interesting to think about all the changes that had happened at the site in the 60 years between when this book was published and when I visited. This book prompted me to search/read more about recent work at the site; a lot has been discovered there between 1966 and now!

Kitchen chemistry hacks explained – How many of these did you know before this article? I knew about lemon juice slowing browning of fruit…I’m going to try the ‘brown onions more quickly’ and ‘chop onions more comfortably.’

Top 10 Things You Didn’t Know About Distributed Wind Power – Interesting update….and map of annual average wind speed at 30 m. There is so much potential in the center of the country. It would be interesting to see the map extended offshore…but maybe that kind of wind power is only used for wholesale generation rather than distributed wind power.

Dust: how the pursuit of power and profit has turned the world to powder – A review of the book about ‘tiny particles doing terrible things’ created by detonation of nuclear weapons, burning coal, and drying of lakes via irrigation. These tiny particles influence our environment, our health, and our relationship with the world around us. They move around the planet through the air…no one is ‘safe’ from them.

More small airports are being cut off from the air travel network. This is why - A shortage of pilots is partially to blame for major airlines' departure from smaller airports. But changing airline economics means the challenge facing regional airports could become insurmountable. Williamsport PA is the example used in the article.

Health evidence against gas and oil is piling up, as governments turn a blind eye – An Australian perspective…but seems to be applicable to many developed countries, including the US. The methane leaks, water contamination, air pollution…why do we continue to push for gas and oil development rather that pivoting to cleaner (and renewable) sources?

Wyoming and Utah Borderlands – A picture from the International Space Station. I remembered a trip to Utah in 2008 where we drove in the area with a Roadside Geology of Utah book explaining the surface geologic features!

New research explains 'Atlantification' of the Arctic Ocean – Changes coming in the Arctic as a 15-year cycle is ending….and the next phase could result in a faster pace of sea-ice loss.

Stone Case Holding Precious Items Found at Templo Mayor – 15 stone figures found at the temple complex of Tenochtitlán, the capital of the Aztec empire. The figures may have already been 1,000 years old when the Aztecs conquered the Mezcala people that carved them. Also in the case: two rattlesnake-shaped earrings, more than 180 green stone beads, snails, shells, and marine corals.

Workers like it when their employers talk about diversity and inclusion - Research has shown that diversity, equity and inclusion (DEI) initiatives improve creativity, innovation, productivity and organizational performance. One of the reasons DEI initiatives have a positive impact is because workers appreciate them. It’s about making sure everyone feels valued and included.

What Does It Take to Photograph a Bat Cave? – Photographer Stephen Alvarez….lots of specialized photographs.

Previously deployed military personnel show retained dust in lungs – The lingering impact of deployments in Afghanistan and Iraq.

As Rio Grande shrinks, El Paso plans for uncertain water future – Preparing for a year when there is no river water. Elephant Butte Reservoir that stores water for Las Cruces NM and El Paso TX, where I went on a birding field trip in November 2016, is currently at 5.6% of its capacity. So far – nothing has resolved the water insecurity of the region into the future.

Watercolor seas in the wake of Hurricane Ian – The impact of water surging and running off…natural-color imagery from NASA’s Terra satellite. There is also an image from the European Space Agency’s Sentinel-2 satellite detailing the coastline near Fort Myers.

Solar Community Slammed by Hurricane Ian: “Our Lights Stayed On” – And another Hurricane story…this one from the ground – Babcock Ranch, about 2 miles from Fort Myers.

Pre-Hispanic images revealed on early convent walls in Mexico – Hmmm….the building was not always a Christian convent?

Has the pandemic changed your personality? – Declines in extroversion, openness, agreeableness, and conscientiousness among adults were measured…particularly in young adults (ages 18-25). I found myself wondering whether the political upheaval that was happening at the same time contributed to the finding; the collective stress levels were probably heightened by more than the pandemic.

A field guide to Jackrabbits – An animal to look for in the west….next time I travel there.

Multiple health benefits of b-type procyanidin-rich foods like chocolate and apples consumed in right amounts – The study showed that peak benefits are achieved at mid-range doses rather than high or low doses. But it is not clear how to get the mid-range dose through diet…which made this article interesting but not actionable.

How did Vikings make glass beads? – Evidently by salvaging Roman and Byzantine mosaics as their raw material!

Scientists are finding fungi in cancerous tumors – A surprise…and lots of research still to be done to understand if the fungi are a correlation or contributor to the tumor.

Carl Lumholtz eBooks

/

I am featuring 5 books, available from Internet Archive, by Norwegian explorer and ethnographer, Carl Lumholtz. His way of working influenced the field of ethnography – broadening the field to include of social relationships, attitudes, and the role of women. The illustrations from 4 books about his work in Mexico skew toward material culture – which was, from the beginning, part of ethnography; he spent longer in the field than most researchers of the time. He was in Mexico off and on between 1890 and 1910.

Decorative art of the Huichol Indians (1904)

New Trails in Mexico (1912)

Unknown Mexico V1 (1902)

Unknown Mexico V2 (1902)

His expedition to Borneo was from 1915-1918 and it turned out to be his last. The sample image I chose from this book is a high-status couple. I was intrigued by the woman’s clothing…of the different kinds of materials and where they might have originated.

Through Central Borneo (1920)

 Lumholtz died in 1922 of tuberculosis.

Snapshots of Indigenous Decorative Art in the early 1900s

/

This week the two books-of-the-week are about decorative art published in the early 1900s about native cultures on opposites sides of the world: The Huichol in Mexico and the Amur tribes in Russia/China (along the Amur River). Both have a relationship to clothing ornamentation.

The sample image from Decorative art of the Huichol Indians by Carl Lumholtz (1904) has a pattern called ‘double water-gourd’ in a ribbon and girdle.

The Decorative Art of the Amur Tribes  by Berthold Laufer(1902) also included designs in metal and ceramics. The designs are common in the broader Chinese decorative arts showing the long-term exchange and cultural linkage with these tribes to the rest of China…at least in the early 1900s. The sample image I chose includes a boot – showing how clothing items incorporated decoration.

I like browsing the books and letting the designs prompt Zentangle tiles. I am reminded that art is not static. It is a representation of the moment it was created – a communication through material culture into the future – different but as potent as the written word.

The oil-field ‘fugitive’ that can slip into the water supply – The methane leaks into ground water are yet another reason fossil fuel is problematic. The industry evidently can’t or won’t clean up…making moving away from fossil fuels as quickly as possible even more urgent – although climate change should be enough for the world to be doing that already.

Top 25 birds of the week: Brown Birds – Not all birds are colorful! Watching small brown birds can be just as much fun though.

Ancient Human Presence Revealed At White Sands National Park - Researchers Push Back Date Of Human Arrival In North America Thousands Of Years – Fossilized footprints in the gypsum sand playa deposits…dated to the Late Pleistocene.

Mexico’s Ancient Inhabitants Moved Land and Bent Rivers to Build Teotihuacán – Still more being learned from an archaeological site that has been studied for many decades. LiDAR is one of new technologies that is yields a lot of new information.

Poorly circulated room air raises potential exposure to contaminants by up to six times – COVID has prompted more detailed research on this topic…and the discoveries should be used to improve building ventilation systems to help control other air-borne diseases.

Why colorful food is good for you – I like the colors and flavors….it’s an added benefit that they are also healthy choices!

NASA’s James Webb Space Telescope Will Launch Into Orbit in December – Finally!

River research reveals scale of macroplastic pollution – A plastic bottle takes a long time to break down….450 years and requires UV light. With so many bottles getting into rivers around the world, it is important to understand how they travel…how they begin to breakdown. They are going to be around for a very long time and, right now, more are still entering the rivers.

Research shows more people living in floodplains – From NASA. Tragedies that are getting worse as population increases and climate change causes flood risk changes.

Making Beetles Pee Can Protect Your Garden – Maybe this is also a pathway to an effective way to control insects like aphids without pesticides!

Entomologists Eradicated the First Asian Giant ‘Murder’ Hornet Nest of 2021 – Includes a picture of the 9 layers of the nest that was carved into an alder tree’s interior.

Turning thermal energy into electricity – It seems like this type of electricity production would have application beyond the military. Even solar panels produce heat and finding a way to automatically harness that into more electricity would be a good thing.  

Climate Change Producing More “Fire Weather” as Far East as Oklahoma – It’s not just the west coast that has a higher risk for fire as the planet gets hotter.

Aztec Pictograms Are the First Written Records of Earthquakes in the Americas – One of the pictograms matched to a 1507 earthquake that coincided with a solar eclipse!

Food systems: seven priorities to end hunger and protect the planet – A thoughtful commentary re ending hunger and improving diets; de-risking food systems; protecting equality and rights; boosting bioscience; protecting resources; sustaining aquatic foods; and harnessing digital technology.

Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk – There was a similar article about pecans a few days ago. I’m glad I like both walnuts and pecans! However – ½ cup is a lot to eat in one day. Usually ¼ cup is considered a serving.

Top 25 birds of the week: Woodpeckers! – I always enjoy hearing a woodpecker in the forest…and its a special tree to see them in our yard. The piliated, downy, and red-bellied woodpeckers are native to our area.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

Identifying sources of deadly air pollution in the United States -- ScienceDaily – Focusing on fine particulates associated with heart attacks, strokes, lung cancer, and other diseases…about half comes from burning fossil fuels; the other half is from animal agriculture, dust from construction and roads, and burning wood for heating/cooking. Ammonia is one pollutant that is not regulated as much as the others and yet it causes a 5th of all deaths caused by fine particulates. It could be reduced with targeted manure management and improving formulations of cleaning supplies, paints, and inks, etc.

Free Technology for Teachers: 500+ Icebreaker Questions – These could also be used as writing prompts…they are good for a bit of self-exploration…useful even if you are not in as many groups right now.

Aztec Palace and House Built by Hernán Cortés Unearthed in Mexico City | Smart News | Smithsonian Magazine – History through layers of stone floors.

Biosignatures may reveal a wealth of new data locked inside old fossils -- ScienceDaily – Not DNA…chemical analysis (using non-destructive Raman spectral analysis) of products of degraded proteins, lipids, and sugars in fossils. Results group into 3 types of biosignatures: biomineralization, tissue, and phylogenic.

Infographic: What Social Isolation Can Mean for the Brain | The Scientist Magazine® - I wondered if the brain structural observations were a cause or effect (or neither). Does the observation that people who are lonely have smaller amygdalae because that are isolated or because they were born that way and it wouldn’t matter if there were a lot of people interacting with them…they would always feel lonely/isolated.

Top 25 birds of the week: July 2020 - Wild Bird Revolution – Always beautiful birds.

Innovative Birds Face a Lower Risk of Extinction | The Scientist Magazine® - Birds that are dropping nuts on roads, stealing burning candles to eat the wick, using bread to lure fish, and pecking open sugar packets…..coming up with new behaviors to cope with new aspects of their environment.

A Silk Road Renaissance - Archaeology Magazine – Many more commodities than silk on the ‘silk’ road: jade, glass, spices, metalwork, ceramic….and missionaries. And the Sogdians were the people that made it work from the 5th to 8th centuries. Panjakent, in modern Tajikistan, has been excavated since the 1940s; many murals have been found depicting myths, fables and everyday life of the Sogdians. In 755 a failed Sogdian coup against the Chinese emperor and thereafter incursion of Arabs from their west caused the culture to fade.

New Research Reveals Surprising Origins of Egypt's Hyksos Dynasty | Smart News | Smithsonian Magazine – Based on chemical analysis of skeletons from the Hyksos capital, the dynasty was likely the result of an immigrant uprising rather than a hostile outside invasion!

Weird and Unbelievable Facts About Earwigs – Entomological trivia…always fun.

Unique Activities for Yesterday:

Blue Jay Behavior.  There was a blue jay on the deck railing making noise….fluttering its wings…making eye contact with 3 or 4 other blue jays around at the time. Those other jays seemed to ignore the ruckus and flew away. Then the bird flew down to the floor of the deck to look for seeds. Maybe it was a fledgling wanting to be fed by the adults…but the adults were forcing the young bird to find its own food? I’m not sure…but I enjoyed witnessing the minute or so of action…whatever it was about. Maybe it was the same jay that tried to get seed from our bird feeder a few days ago (and failed).
