Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance? – A diverse array of microorganisms were found in the hot waters of the Roman Baths. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

The Changing Nature of Wilderness - The U.S. government has begun to acknowledge the Indigenous history of ‘wilderness’ areas and, in some (very few) cases, restored land to native tribes or created co-management agreements.

Nearly 25% of land in Africa has been damaged – What’s to blame, and what can be done - The “big five” drivers of land degradation globally and in Africa are:

• biological invasions, where plant species have spread outside their indigenous area and disrupted the services provided by ecosystems

• climate change driven events, such as intense droughts and severe fires

• extractive activities, such as mining and over-harvesting

• habitat transformation or fragmentation, including deforestation and poor agricultural practices

• pollutants such as sulfur dioxide, and eutrophication – where algae and other plants take over plant life.

The Hunt: Genghis Khan’s Final Resting Place - His last wish was to be buried in secret, something his soldiers accomplished in two ways: by killing everyone they met enroute to the gravesite, and then trampling that site under the hoofs of their horses until no trace was left. Although tomb culture, inherited from the neighboring Chinese, was well-established by the time Genghis Khan was born, many were constructed underground, some at a depth of more than 65 feet. Most Mongolians today would prefer that Genghis Khan’s tomb stayed hidden. Not because discovering it would unleash an ancient curse—a superstition that was actually quite widespread in Soviet times—but simply out of respect for the historical figure’s dying wish.

Airplane noise exposure may increase risk of chronic disease - Research has shown that noise from airplanes and helicopters flying overhead are far more bothersome to people than noise from other modes of transportation, and a growing body of research suggests that aircraft noise is also contributing to negative health outcomes.

New fossils show what Australia’s giant prehistoric ‘thunder birds’ looked like – and offer clues about how they died out - While the birds had broad, short toes and hoof-like claws for moving across open ground between bodies of water, their partial reliance on freshwater and new plant growth would have become more difficult as ponds and lakes shrunk and disappeared.

Phoenix Heat Deaths Rose by 1,000 Percent in 10 Years - Relentless heat led to 645 deaths last year in Maricopa County, the most ever documented in Arizona’s biggest metropolitan area. Almost half of the victims last year were homeless — 290 people. Twenty died at bus stops, others were in tents, and an unrecorded number of people were found on the pavement, prone as if on a baking stone.

Warming Brings Early Bloom to Bulgarian Rose Fields – Bulgaria is a top producer of rose water and rose oil. To produce these goods, pickers must harvest the flowers early in the morning, when their petals are richest in oil. After a mild winter and warm spring, pickers in Bulgaria’s Rose Valley have headed to the fields around three weeks earlier than normal.

Meet the World’s Largest Freshwater Crayfish – The Tasmanian giant crayfish. Their numbers are declining due to fishing and disturbance.

FDA urges Congress to pass bill mandating food manufacturers test for lead – I am surprised Congress did not pass this already. According to the U.S. Disease Control and Prevention, there have been at least 519 confirmed, probable and suspect cases of lead and chromium poisoning traced to imported applesauce pouches produced by brands WanaBana, Schnucks and Weis. Lead exposure in children is associated with learning and behavior problems, as well as hearing and speech issues and slowed growth and development.

Retention ponds can deliver a substantial reduction in tire particle pollution - The presence of wetlands and retention ponds alongside major highways led to an average reduction of almost 75% in the mass of tire wear particles being discharged to aquatic waters. Tire wear particles significantly outweighed other forms of microplastics, such as plastic fibers and fragments.

Climate change is fueling the US insurance problem – I’ve seen more articles about this recently….there is no good news re insurance…nothing that can overcome what climate change is doing. One state-level action that could help mitigate the impacts of climate change is the implementation of flood disclosures. Organizations like the Natural Resources Defense Council have urged states to require flood disclosure polices during property sales to help buyers decide whether buying is worth the risk. Research has shown disclosure can devalue flood-prone properties and discourage development in risky areas. Even though the number of states requiring flood disclosure policies is slowly increasing, Florida remains noticeably absent, and one-third of states still have no requirement that sellers must disclose a property's flood risk to potential buyers.

Does the time of day you move your body make a difference to your health? – Maybe – for people living with obesity.

How the iron lung paved the way for the modern-day intensive care unit – The iron lung was first used to save the life of a child in 1928. It swiftly became a fixture in polio wards during the polio outbreaks of the subsequent decades, particularly from 1948 until the vaccine was developed in 1955. And its creation paved the way for many subsequent medical innovations. Some patients spent just a short time in the iron lung, perhaps weeks or months until they were able to regain chest strength and breath independently again. But for patients whose chest muscles were permanently paralyzed, the iron lung remained the key to survival.

Food security in developed countries shows resilience to climate change - Data on American wheat production, inventories, crop area, prices and wider market conditions from 1950 to 2018, together with records of annual fluctuations in the weather for the same period reveals strong evidence of an increase in weather and harvest variability from 1974 onwards. However, Wheat prices remain relatively stable, along with the price of associated goods mainly due to farmers and agricultural industries providing a buffer, smoothing out any bumps in the supply of grain to retailers and consumers.

Where the Xerces Blue Butterfly Was Lost, Its Closest Relative Is Now Filling In - Silvery Blues collected 100 miles south of San Francisco were released at a restored a swath of dunes in the Presidio, a former military base, trying to bring back native wildlife. They will pollinate native flowers and form a critical link in the food chain there.

Colorless, odorless gas likely linked to alarming rise in non-smoking lung cancer - 5-20% of newly diagnosed lung cancers occur in people who have never smoked, many of whom are in their 40s or 50s.  Non-smoking lung cancer cases is likely linked to long-term, high exposures of radon gas. This colorless, odorless gas is emitted from the breakdown of radioactive material naturally occurring underground that then seeps through building foundations. The gas can linger and accumulate in people's homes and lungs silently unless they know to test for it. We had our Missouri house tested and radon remediation installed before we moved it!

Contents of Roman Lead Coffin Examined in England - The examination of the contents of a Roman lead coffin discovered in 2022 in the city of Leeds has identified the partial remains of a child (about 10 years old). The initial evaluation of the coffin’s poorly preserved contents found the remains of a woman between the ages of 25 and 35 at the time of her death some 1,600 years ago, a bracelet, a glass bead necklace, and a finger ring or an earring.

Just how big can a snowflake get? It depends on what you mean by 'snowflake' - A snow crystal with six-fold symmetry is the kind of snowflake you might cut out of folded paper with scissors. But the word "snowflake" also can refer to white puffballs that drift down from the sky, which are made of many individual snow crystals that have collided and gotten entangled.

Treating tuberculosis when antibiotics no longer work - Substances that have a dual effect against tuberculosis: They make the bacteria causing the disease less pathogenic for human immune cells and boost the activity of conventional antibiotics.

Planning a city that gets people moving – Lake Wales, Florida has a plan to create a built environment that promotes mobility through walking, cycling, e-biking, or other means of transportation beside automobiles. One way to do that is through proximity—to a park, multiuse pathway, protective bike lane, or walkable destination. Another is to ensure that the environment is pleasant for walking or using a bicycle.

The qualities that are more attractive than our looks - When it comes to finding the right match agreeableness accentuates the benefits of other parts of our personalities. It really could pay to be kind after all.

Archaeologists Uncover ‘Exceptional’ Ancient Mural Near Colosseum - Crafted of shells, a special volcanic stone called pozzolana, marble, colored glass, and Egyptian tiles found in the remains of a house from more than 2,000 years ago. Its intricate designs show weapons and instruments hanging alongside ships and tridents. Archaeologists think a wealthy Roman officer commissioned it after a military success. Whoever the owner was, he may not have stayed wealthy for long. Evidence suggests that his family fell out of favor when the Roman emperor Augustus came to power. The building and its contents were later buried and replaced with a grain store built directly on top of it.

A Lake Born out of an Earthquake – Earthquakes can fundamentally reshape the landscape, reroute rivers, and even form new lakes. Consider the northwest corner of Tennessee in the early 19th century. Between December 1811 and February 1812, three earthquakes with magnitudes greater than 7 occurred in the New Madrid seismic zone, which encompasses southeastern Missouri, northeastern Arkansas, and neighboring parts of Tennessee and Kentucky. The last of these quakes, on February 7, 1812, centered near New Madrid, Missouri, was especially notable: It temporarily rerouted the Mississippi River, permanently dammed the Reelfoot River, and directed water to fill in a low-lying area to form Reelfoot Lake. More than two centuries later, Reelfoot Lake remains a persistent feature on the Tennessee landscape. An image from Landsat 9 shows the area in late 2023. The area of lake and surrounding wetlands is a state park and national wildlife refuge.

Cats Prey on More Than 2,000 Different Species - Scientists have long known that free-ranging cats—those that spend unsupervised time outdoors—can affect biodiversity by hunting and eating insects, birds, reptiles and mammals. Researchers sifted through hundreds of previous studies, books and reports to put together a database of every animal cats have been recorded eating, as well as the location. In the end, their list featured 2,084 species, which includes 981 birds, 463 reptiles, 431 mammals, 119 insects and 57 amphibians, plus 33 additional species from other groups. Some of the creatures that made the list—including humans—are too large for cats to hunt but reflect their scavenging tendencies. Though the findings are useful, some scientists say they distract from a much larger threat to biodiversity: humans.

Autistic people experience loneliness far more acutely than neurotypical people -Small adjustments to lighting, acoustics, decor and wayfinding, among other sensory factors, can significantly reduce the burden on people with sensory processing differences and open up more social spaces to them.

Inhalable sensors could enable early lung cancer detection - The new diagnostic is based on nanosensors that can be delivered by an inhaler or a nebulizer. If the sensors encounter cancer-linked proteins in the lungs, they produce a signal that accumulates in the urine, where it can be detected with a simple paper test strip. It could replace expensive CT scans for lung cancer (and be more accurate…not as many false-positives).

This Photographer Captured One Image of Cambridge (England) Every Day for 13 Years - After 5,000 photos, Martin Bond has decided to conclude his project, which showcased the city’s mundane and extraordinary moments. “The best thing about street photography ... is that it is possible for the final viewer of a picture to see more than the original photographer—proof, if any were needed, that there is more going on in any moment than a single person can understand.”

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

What links litmus paper and lichens? – How did I not know that litmus dye was made from lichens? I remember using red cabbage to tint paper for an elementary school science project with my daughter. We tested everything in the house…discovered that even the fumes from toilet bowl cleaner turned the strips we made bright pink!

How donkeys changed the course of human history – The beast of burden. During Roman times the subspecies used was larger than modern donkeys…specifically bred for the expanding empire.

Jungle realm of the Snake Queens – A 5-part article about 2 Mayan queens: Lady K’abel and Lady Six Sky.

Marriage in Minoan Crete – A surprise – it was very common to marry one’s first cousin!

Kenya’s Rift Valley lakes are rising, putting thousands at risk – A study reveals that there have been increases in rainfall since 2010…an increase of only 0.4-2% of mean annual rainfall leads to the observed rising lakes/flooding.

EPA requirement keeps electric buses out of low-income schools – Low-income school districts often don’t own their school buses; they rely on contractors or subsidized lease deals. So --- they can’t meet the requirement to scrap the old diesel buses.

Ten-minute scan enables detection and cure of the commonest cause of high blood pressure – The hormone aldosterone causes 1 in 15 cases of high blood pressure. This new technology/treatment is a big improvement for the way those cases can be treated.

Dead Humpback Whale Washes Ashore at Assateague Island – This is the second one recently. I am familiar with the place this time…Assateague Island was a place my husband and enjoyed for birding when we lived in Maryland.

China’s population declines for the first time in six decades – Changing demographics in China.

Bees exposed to common weedkiller via wildflower nectar – Evidently the flowers can be contaminated even if they are not sprayed directly!

Musings from the parks: Navigating National, Wild, Recreational, and Scenic Rivers – Prompted by a proposal to refine limits on the horsepower boaters can use in Ozark Scenic Riverways in Missouri…a look at regulations at other rivers in the National Park System. I’d prefer that we begin the transition to electric motors (if motors are allowed at all) rather than only focusing on horsepower.

Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging – A blood test to measure the pace of biological aging…with the possibility of identifying interventions that would slow aging… and attempt to build aging health equity.

Art and Archaeology – An Illustrated Magazine

There are 11 volumes of the Art and Archaeology magazine from 1914-1923 available on Internet Archive; it was published in Baltimore. Most of the illustrations are black and white photographs but there are occasional color ones. I enjoyed finding pictures that looked familiar…and realizing how long some of the places and artifacts have been featured in magazines: the Aztec and Maya from Central America; buildings in Greece and Italy and Spain and France from Europe; Egypt, Babylon, and Petra from the Middle East; the desert Southwest and Lincoln of the US….and these are just what is represented in the 2 sample images I picked from each volume. Some of the places are probably a bit more worn from tourists and damaged by air pollution 100 years later…some have been restored. Maybe I will do a side by side look at some historical pictures of a place I visit (when I start doing that kind of traveling again).

I hope that more of volumes of this magazine become available as the copyright expires; it was published into the 1930s. For now – enjoy the sample images below by clicking through the 22 images…or go to the volumes directly by following the 11 links.

V1 (1914-1915), V2 (1915), V3 (1916-1), V4 (1916-2), V5 (1917), V7 (1918), V9-10 (1920), V11-12 (1921), V13-14 (1922), V15 (1923 - 1), V16 (1923 -2)

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

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

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

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

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

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

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

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

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

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

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.

Why cavemen needed no braces – Our diet and behavior have changed a lot since the stone and hunter/gather stages of our species….and those changes have impacted our jaw (and teeth and air way). There are more health consequences than just crooked teeth. I’ve bought the book (Kindle version) to learn more.

Characteristics that give viruses pandemic potential – An article from The Scientist that is more future oriented. What we are experiencing with COVID-19 is something that could happen again. The article talks about various types of viruses that pose the greatest threats.

Amazing Macro Winners of the International Garden Photographer of the Year 2020 – Visual treats. This it the type post that gives me ideas about things to try with my own camera.

1,200-Year-Old Soap Factory Unearthed in Negev Desert – The soap was made from olive oil and the ashes of the saltwort plant. The factory produced enough for export to places like Egypt and other parts of the Arab world.

Low humidity increases COVID-19 risk: Another reason to wear a mask – This finding does not bode well for the winter when many homes and workplaces have much lower humidity because of furnaces.

Top 25 birds of the week: Birds in Pairs – Beautiful birds….I always enjoy looking at the 25 pictures each week.

Hawaiʻian Snails: A Tale of Discovery and Rediscovery – I remember seeing a snail in a planter box at the airport on the big island while I was waiting for my luggage a few years ago…and I dug up the picture I took when this article prompted the memory.

Wolverines Seen Roaming About Mount Rainier National Park – What a boon remotely triggered cameras can be….and then DNA testing of hair to determine relationships!

 Meet the Squad of Mosquito-Eating Species – Birds, dragonflies, newts, aquatic turtles, and bats. We haven’t noticed very many mosquitoes around this year, but we try to replace the water in our bird baths frequently and make sure our gutters are draining properly. Having the birds around our house probably helps…and the turtles at the neighborhood pond do their part.

Unique Activities for Yesterday:

Going to the basement during a storm. Our phones went off with tornado warnings – which is rare in Maryland. We went to the basement. It turned out to be only heavy rain for us (not very windy either); to the east and south of where we live there was a lot of damage with trees/big branches falling and shingles flying.

Cleaning the leaves off the deck. Over the past week we’ve had several fronts come through that have blown leaves and branches onto our deck. They were still wet when I went out to clean up. I dumped the sediment that had accumulated in the bird bath too.

Finding Witches’ Butter. I photographed the fruiting bodies of Witches’ Butter on our deck railing. The deck is over 25 years old and even regular treatment can’t keep it clear for fungus; it is only visible during times when the wood is wet for several days.  

I’m more concerned about a window frame that has the same fungus growing. I’m not keen about replacing the window but we might have to consider it.

Why some older adults remember better than others -- ScienceDaily – The article seems to be more about the technology that enables these studies….hints at findings that may eventually be actionable.

The World’s Forests Are Getting Younger and Shorter, Research Finds - Yale E360 – This article is a little confusing. It says that ‘climate change is altering the age and structure of the world’s forests’….but it’s more than climate change. It’s also land use decisions (like logging , conversion to agriculture, introduction of invasive species) that have changed the forests. I was disappointed in the article although the last sentence seems obvious: “We as a human society are hitting these forests so rapidly with so many different changes that they can’t keep up.” Now the big question is – what are we going to do about it?

Remains of 60 Mammoths Discovered in Mexico | Smart News | Smithsonian Magazine – North of Mexico City.

Ancient Roman Mosaic Floor Unearthed Beneath Italian Vineyard | Smart News | Smithsonian Magazine – Finally returning to a site first discovered in 1922 and making this find within a week of starting excavations. The mosaic floor is well preserved a few meters below the vineyards surface and is thought to date from the 3rd century AD.

The Infant Gut Microbiome and Probiotics that Work | The Scientist Magazine®  - Evidently the infant microbiome has changed in the past 100 years…even among breastfed babies. And maybe that explains some of the immunologic problems in young children. There are indications that the probiotic helps babies nutritionally and immunologically.

Two bacteria allow spittlebugs to thrive on low-nutrient meals -- ScienceDaily – One of the bacteria uses aerobic glycolysis to process glucose to synthesize 7 essential amino acids plus 2 biproducts that the other bacteria uses to create ATP to produce 3 additional essential amino acids. It’s a similar two cell type process used by cancer cells.

An Encounter with Mating Gopher Snakes – Springtime out in nature…. this article from Idaho.

The gilded mummy of Lady Isaious | Egypt at the Manchester Museum – A Graeco-Roman Period mummy from the 1st century CE.

Unique activities for yesterday:

A large Zentangle tile. I printed a page (on card stock) from The genera of the plants of the United States illustrated by figures and analyses from nature by Asa Gray and Isaac Sprague published in 1848 available from Internet Archive.

Then I used the lotus as the ‘string’ for an 8.5x11 Zentangle tile. Like most strings….it mostly vanished. It took me about three days working for short periods of time to finish. Next time I’ll use more colors so that the botanical print ‘string’ remains more visible.

Nations with strong women's rights likely to have better population health and faster growth-- ScienceDaily – A study analyzed databases which held information on health, human rights, and economic and social rights for 162 countries for the period 2004 to 2010.  The results suggest that gender equality is not just a women’s issue but a development issue.

More Climate Surprises Expected – THE DIRT – “Climate change together with environmental degradation and social and political instability is the threat multiplier.” It seems like more and more climate-linked surprises/disasters are happening every year. When do we reach a tipping point where everyone realizes that we cannot continue the status quo?

Viking Woman Warrior May Have Been Slavic | Smart News | Smithsonian – Not all ‘Vikings’ were Nordic men…some were Slavic and some were women! It’s good to understand long ago cultures in more depth…particularly when it causes us to rethink our assumptions.

Top 25 Wild Bird Photographs of the Week: Birding – National Geographic Society Newsroom – Variety and beauty of birds…I always enjoy the ‘25’ collections.

How to keep buildings cool without air conditioning – according to an expert in sustainable design – We are going to need all the technology we know (and some new ones) to keep buildings and homes cool as the planet gets warmer.

America's packaged food supply is ultra-processed: Americans are overexposed to products that are high in calories, saturated fat, sugar and salt -- ScienceDaily – Unhealthy ‘food’ --- most of us have an inkling about this but it doesn’t keep us from indulging. The article mentions the Foodswitch app that allows consumers to scan packaged foods to determine their healthfulness; I loaded the app and scanned things in my pantry. The pasta I buy (whole wheat and green) rates a 5 of 5! Soymilk was 4.5. The canned tamales my husband likes are a 3 (salt and fat).

Thamugadi, a Roman outpost in Algeria, was saved by the Sahara – Buried in sand after it was abandoned around AD 700…and rediscovered in the 1700s but not explored. In the 1870s it was again rediscovered. It was excavated by the French from 1881 to 1960 in its entirety. It became a UNESCO World Heritage site in 1982.

100 days, 100 nights: Sensor network reveals telltale patterns in neighborhood air quality: Custom-built sensors deployed for 100 days and nights to track black carbon pollution -- ScienceDaily – A test was done in West Oakland with new technology to monitor air pollution with more specificity over the area and time of day(s) than has been done before now. The technology worked and demonstrated that the finer grain measurements provide deeper understanding of what impacts localized air quality…something we have to understand to make progress in improving city environments.

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.

Narwhals and belugas can interbreed -- ScienceDaily – It is a unique case….apparently not something that is common at all. It also utilized some relatively recent analytic tools to determine that the hybrid was a first-generation hybrid between a female narwhal and male beluga…and it was a bottom feeder rather than feeding like either of the parents.

Photography in The National Parks: Where Will That Trail Take You? Creating A Theme – For me - themes most often emerge from the experience rather than something I think about specifically in advance.

Cholesterol medication could invite diabetes, study suggests: Patient data shows association between statins and type 2 diabetes -- ScienceDaily – A drug prescribed to reduce risk of heart attack and stroke…doubles the risk of diabetes diagnosis which would require other drugs to treat…for the rest of the person’s life. Not a good prospect.  

The Pomological Watercolors: A Collection of Watercolor Fruit Paintings – Watercolors of fruits and nuts created over 56 years beginning in 1886 by the US Department of Agriculture. They have recently been digitized and are available via the Pomological Watercolor Database. It’s not as easy to browse as a book in Internet Archive, unfortunately.

Ice Cores Preserved 1,500 Years of Industrial Lead Levels - Archaeology Magazine – I was surprised that lead levels in the atmosphere now are 60x higher than in the medieval period and that is an 80% decline since the enactment of the 1970 Clean Air act in the US. How is the lead in the air we breathe impacting our cognition – particularly for children?

Found: An ‘Undisturbed’ Roman Ship Near Cyprus | Smart News | Smithsonian – Lots of amphorae. Cyprus’ location would have made it a link on the trade route that spanned the Mediterranean but studying a wreck like this one could fill in more of the details.
