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.

Can autoimmune diseases be cured? - After decades of frustration and failed attempts, scientists might finally be on the cusp of developing therapies to restore immune ‘tolerance’ in conditions such as diabetes, lupus and multiple sclerosis.

Good and bad news for people with low back pain - The good news is that most episodes of back pain recover, and this is the case even if you have already had back pain for a couple of months. The bad news is that once you have had back pain for more than a few months, the chance of recovery is much lower. This reminds us that although nearly everyone experiences back pain, some people do better than others, but we don't completely understand why.

Why diphtheria is making a comeback - While this present surge of diphtheria cases is indeed unprecedented for West Africa, it is really a symptom of larger issues in global health, including insufficient infectious disease surveillance, poor vaccination rates and scarcity of public health resources.

The Prairie Ecologists Photos of the Week – January 22 2024 – Photographs from out in the cold.

The chemistry of meat alternatives – It’s complicated…..in the end are meat alternative ultra-processed food?

The strange reasons medieval people slept in cupboards – I can see how they might have been warmer….but also rather claustrophobic. And wouldn’t they be hard to keep clean?

In the time of the copper kings - Some 3,500 years ago, prosperous merchants on Cyprus controlled the world’s most valuable commodity. Beginning in the third millennium B.C., and especially during the second millennium B.C., copper was king and could make those who possessed it extremely wealthy and powerful. There was enough copper and tin on board the Uluburun ship (wrecked off the coast of Turkey) to produce 11 tons of bronze, which experts estimate could have been turned into 33,000 swords. Researchers have analyzed the Uluburun wreck’s copper and found that it all came from Cyprus. There is evidence of the surprisingly diverse nature of the community thriving there and that those Cypriots who controlled the production and distribution of copper, such as the shipment found off Uluburun, could become exceptionally rich.

Cicadas Are Coming: Rare ‘Dual Emergence’ Could Bring One Trillion of the Bugs This Year – We don’t live in the overlap area…but where we live in Missouri will see Brood XIX this summer….a great opportunity for cicada photography!

Incredible Winners of the Close-Up Photographer of the Year Contest – So many beautiful images. My favorite is ‘Spirit of Yucatan’ (drifting stems of lily pads in a Mexican freshwater cenote…the sky above).

Deepwater Horizon oil spill study could lead to overhaul of cleanup processes worldwide – Chemical oil dispersants combined with sunlight…made oil more toxic. Observations from after Deepwater Horizon, and being confirmed experimentally, to improve responses to oil spills.

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.
