Versailles’s Hidden Scientific Legacy to Surface in a Major U.K. Exhibition - The five-mile-squared grounds were mapped out by geometricians and astronomers; keeping the 14,000 fountains bubbling further required developing an unprecedented hydraulic engineering system. AND… Giovanni Domenico Cassini, who headed the Paris Observatory, turned skyward, mapping the moon with a precision that wouldn’t be matched until the late 19th century. AND… Hundreds gathered in the courtyard of Versailles to watch the flight of a hot-air balloon, agronomists developed a hardier potato capable of feeding the masses, and an inoculation against smallpox was discovered.

Air conditioning causes around 3% of greenhouse gas emissions. How will this change in the future? – The article concludes: “Rather than lamenting air conditioning's impact on energy use, we need to accept that demand for cooling will increase, work on making it affordable for those who need it most, and build efficient solutions that ensure electricity grids worldwide can cope.”

Ancient Rome’s Appian Way Is Now a UNESCO World Heritage Site - Rome’s Appian Way, an ancient highway dating to the fourth century B.C.E., has been declared a UNESCO World Heritage site.

Could the shingles vaccine lower your risk of dementia? - The idea that vaccination against viral infection can lower the risk of dementia has been around for more than two decades. Associations have been observed between vaccines, such as those for diphtheria, tetanus, polio and influenza, and subsequent dementia risk. It may be the resulting lack of viral infection creating this effect. We need more research exploring in greater detail how infections are linked with dementia. This will help us understand the root causes of dementia and design potential therapies.

Chickasaw National Recreation Area's Monkey Tree Needs Some TLC - An Osage orange tree estimated to be about 130 years old with three thick spreading trunks that generations of children have played on.

Divers Discover Mesmerizing Roman Mosaic Beneath the Sea – Near Naples…a villa in a city known as the Las Vegas of the Roman Empire…now under water.

Healthy diet with less sugar is linked to younger biological age – The correlations between a diet that is rich in vitamins and minerals, especially one without much added sugar, and having a younger biological age at the cellular level.

Agriculture: Less productive yet more stable pastures - Grassland optimized for high yield responds much more sensitively to periods of drought than less intensively used meadows and pastures.

Anne Boleyn’s Childhood Home Is Restored to Its Tudor Glory – The interiors of rooms restored to the style they had during Anne Boleyn’s time.

Forest carbon storage has declined across much of the Western U.S., likely due to drought and fire – Forests in some parts of the world, like the American West, probably do not have the potential to help curb climate change.

Tax Burden by State – A comparison done by WalletHub that compared the 50 states on 3 types of taxes - property taxes, individual income taxes, and sales and excise taxes - as a share of total personal income in the state.

See a Restored Ancient Roman Helmet—and Two Shiny New Replicas – 2,000-year-old helmet made of silver-gilded iron.

Solar Savings in the US – Looking at the numbers….

Feral Hogs to Be Removed from Congaree National Park – My husband and I visited Congaree in 2008 and I vividly remember the feral hogs. Evidently action is being taken to remove them. They have become a pervasive problem to both the park and surrounding landowners, routinely causing widespread damage to land and water resources both within and outside of the park. Recent observations have shown that they have begun to cause more extensive damage to areas near the Harry Hampton Visitor Center, including areas where synchronous fireflies are active and where restoration of longleaf pine is ongoing.

What four decades of canned salmon reveal about marine food webs - The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Researchers dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms -- a common, tiny marine parasite -- within the flesh. The parasites were killed by the canning process but still visible… counting them is one way to gauge how well a marine ecosystem is doing.

Texas Solar Power Growth Changing the Shape of Daily Electricity Supply in ERCOT – Looking at the changes between 2022 and 2023…easy to see graphically.

Functional capacity in old age is like an ecosystem that may collapse when disrupted - In old age, a tighter interlinkage between different domains of functional capacity may indicate a loss of system resilience. When functional capacity domains are tightly interconnected, a disruption in one domain can affect others and lead to a collapse in functioning.

Ming Dynasty Tomb Found in China's Xinfu District – Part of excavations before nearby highway construction begins.

I spy with my speedy eye: Scientists discover speed of visual perception ranges widely in humans - The rate with which we perceive the world is known as our "temporal resolution." Though our visual temporal resolution is quite stable from day to day in general, a post-hoc analysis did suggest that there may be slightly more variation over time within females than within males.

Study Reveals Vast Networks of ‘Ghost Roads’ in Asian Rainforests - An extensive analysis of satellite imagery has uncovered thousands of miles of unmapped roads slicing through Asia’s tropical rainforests - “ghost roads” may be laid down by miners, loggers, poachers, drug traffickers, and land grabbers, often illegally.

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.

Top 25 birds of the week: Shorebirds! – Always lots to see looking at birds!

Everglades' Wading Birds Had Mixed Success In 2020 – Overall wading bird nesting in South Florida has increased…but is still a fraction of the target. In 2020, an early arriving rainy season impacted the availably of food for chicks.

De-cluttering may not help people with dementia – People with moderate dementia perform better surrounded by their ‘usual’ clutter!

U.S. Is World’s Top Generator of Plastic Waste – Not surprising. And the US should take the lead in figuring out what to do about it: how to produce less and recycle more.

A Mosaic From Caligula’s ‘Pleasure Boat’ Spent 45 Years as a Coffee Table in NYC – Still a lot of mystery about how the mosaic got from its recovery when Lake Nemi was drained by Mussolini and then becoming the top of a coffee table for 45 years. It was seized in 2017 and returned to the Italian government.

Roadrunner: Meet the Real Bird Behind the Cartoon – I can remember seeing one a little north of where my parents live now (north of Dallas) in the 1980s…but they are probably long gone from that area now. I’ve seen them in west Texas more recently; one was at a rest stop between San Antonio and Laredo. They always seem to thrive in relatively harsh environments.

The bustling hidden world of hedgerows – The closest we come in North America to hedgerows are fencerows or windbreaks….and even those have been reduced over the years. Near where I live the advent of glyphosate/Roundup ready crops has eliminated the herbaceous growth along the edges of fields which in the past included milkweed and other plants that were attractive to butterflies and other small animals.

Master Artisans Fixed Mistakes Made by Apprentices at Ancient Egyptian Temple – I enjoyed the 6 minute video in this post…it’s quiet enough to hear the birds in the ruins.

Managing water resources in a low-to-no-snow future – We need to be thinking of adaptations to this manifestation of climate change now rather than waiting since the solutions will be challenging….take time to design and construct.

Old-fashioned rice custard – I have a container of rice from some Chinese takeout…..and plan to make this rice custard. I am anticipating that it will be yummy (and high protein too).

Virginia Museum of Fine Arts – Part 2

Continuing the highlights from our visit to the Virginial Museum of Fine Arts….

The Ancient gallery is dedicated to Egyptian, Greek, Roman and Etruscan art. I was glad the museum permits (non-flash) photography because there were lots of Zentangle prompts in the pots. Thinking about how old some of them are…how amazing it is that they survived…that they still appeal to us now. Some of them appeared to be more functional objects than art but may those pieces tell us more about the lives of long-ago peoples that things intended only for display or another special purpose.

I’d never seen an Egyptian bust that was intentionally made from a rock with a vein of another color across the face. It is quite striking and was the ‘style’ for a short period of Egyptian history.

In the East Asian gallery, there was black screen with botanical images. It did not look as impressive until I zoomed with the camera and made out the detail of the images.

Other items from the East Asian gallery provided a diversity of styles and materials. The small bowl is made from agate.

Back for a last look as some pieces from the Ancient gallery….gold piece from a crown, more pottery, jewelry and two small friezes.

For a short walk around, we saw a lot of interesting (and beautiful) things!
