This cool new approach to refrigeration could replace harmful chemicals

S70

This cool new approach to refrigeration could replace harmful chemicals Scientists at Lawrence Berkeley National Laboratory have developed a novel potential means of alternative refrigeration: ionocaloric cooling. The method involves electrically charged atoms or molecules (ions) changing the melting point of a solid material, much like adding salt to roads before a winter storm changes how ice will form. Their proof-of-principle experiment used salt made with iodine and sodium along with an organic solvent to achieve energy-efficient cooling, according to a recent paper published in the journal Science.

The true story behind the US' first federal monuments "Are you sitting down? I have news for you." Gwen Marable's cousin from the US state of Ohio called her at home in Maryland about 27 years ago. "We are descended from the sister of Benjamin Banneker, Jemima." The Banneker family, which numbers over 5,000 known descendants today, only learned about this astonishing connection to their ground-breaking but little-known ancestor through the wonders of DNA testing. As such, no personal stories about him, no artifacts, were handed down through the generations. Continued here

Biden taking "absolutely wrong approach" to crack down on Big Tech, critics say As president, Joe Biden has made it clear that he wants to lead the charge to change how Big Tech operates in the US.

Only with bipartisan action, Biden said, can the US do more to protect data privacy, prevent anti-competitive behavior, and “fundamentally reform Section 230,” by reversing course and holding platforms accountable for third-party content.

You're not imagining it--new cars really have gotten much more expensive The average transaction price of a new vehicle rose by 4.9 percent in 2022, according to Kelly Blue Book. As a result, the average sales price of a new vehicle in December was $49,075, a $2,297 increase over 12 months earlier. (Average sales prices were higher than MSRP thanks to factors like dealer markups.) Some of the rise is a consequence of a lack of inventory, which was at its lowest level ever early in 2022 due to factors like supply chain shortages caused by the pandemic and the Russian invasion of Ukraine. But prices have continued to rise even as more new cars have made their way to dealer lots. Continued here

Ancient Americans Crossed Back into Siberia in a Two-Way Migration, New Evidence Shows Scientists have long known that ancient people living in Siberia made their way into what is now North America. Mounting DNA evidence suggests migration also happened in the opposite direction Science has long known that people living in what is now Siberia once walked (and later paddled boats) across the Being Strait into North America. But new evidence now shows that these early migrations weren’t one-way trips: in a study published on Thursday in Current Biology, researchers say they have uncovered traces of Native American ancestry in the DNA of Siberians who lived centuries ago.

Duna de Bolonia: The Spanish sand dune hiding Roman ruins Near the southern tip of Spain's Cádiz province, where Europe lunges into the Strait of Gibraltar as if reaching out for the North African coast, the Duna de Bolonia is one of the continent's largest sand dunes. Rising more than 30m high and sprawling 200m wide, the white mound spills into the azure sea and appears as if someone has dumped a massive pile of sugar atop the surrounding Estrecho Nature Park's protected green forest. Like all sand dunes, Bolonia is a constantly moving ecosystem that shifts with the winds. But as climate change has intensified the hurricane-force gusts coming from the east, the dune has increasingly migrated inland towards the ecologically important cork and pine forests and scrubland – revealing remnants of the many past cilivilisations who have passed through here in the process.

Why we can't look away from Mexico City's gentrification Happy 2023! Or is it still 2022? You can’t tell going by the incessant, and near identical, reporting about the gentrification of Mexico City by digital nomads. You might even remember reading my own thoughts in this newsletter about whether tech was a force for gentrification in Latin America — 11 months ago! Only a few articles have actually moved the story forward, so why are we still talking about this? On the face of it, the gentrification of Mexico City feels like a story that has repeated across many moments in history: class conflict, migration, displacement. And yes, it is fundamentally about those things. More recently, though, I’ve been thinking that this story also reflects something very specific about the time and place we are living in right now.

Sedimentation threatens to steal capacity from nearly 50,000 dams Slowly but surely, the world’s reservoirs are getting gunked up with sediment. In an unblocked river, the flowing water carries bits of sediment along—picked up from river banks or swept into the river from rain. However, rivers whose flow has been interrupted by a dam deposit some of that sediment right behind the dam itself, in the reservoir. “Gradually, [over] years and years, it will be accumulating,” Duminda Perera, a researcher with the United Nations University Institute for Water, Environment, and Health in Hamilton, Ontario, told Ars.

But with a little bit of sticky tree resin and a lot of luck, delicate bits of plants and tiny critters can sometimes last for tens of millions of years.

The ancient remains of Great Zimbabwe Walking up to the towering walls of Great Zimbabwe was a humbling experience. The closer I got, the more they dwarfed me – and yet, there was something inviting about the archaeological site. It didn't feel like an abandoned fortress or castle that one might see in Europe: Great Zimbabwe was a place where people lived and worked, a place where they came to worship – and still do. It felt alive.  Great Zimbabwe is the name of the extensive stone remains of an ancient city built between 1100 and 1450 CE near modern-day Masvingo, Zimbabwe. Believed to be the work of the Shona (who today make up the majority of Zimbabwe's population) and possibly other societies that were migrating back and forth across the area, the city was large and powerful, housing a population comparable to London at that time – somewhere around 20,000 people during its peak. Great Zimbabwe was part of a sophisticated trade network (Arab, Indian and Chinese trade goods were all found at the site), and its architectural design was astounding: made of enormous, mortarless stone walls and towers, most of which are still standing.

No atmosphere found on JWST’s first Earth-sized exoplanet For many of us, when we turn our eyes skyward, we imagine much, much more than the stars, galaxies, and the expanse of empty space that separates them. Instead, we turn our thoughts to the worlds that orbit each one of those stars: massive, gas giant planets with their own rich systems of moons, planets with solid surfaces like the Earth, Venus, Mars, and Mercury, and planets in between those two, like the so-called super-Earths that are almost exclusively more like mini-Neptunes. Each world in the Universe is unique, with its own composition, formation history, and possibilities for what sort of chemical or even biological reactions might occur there. For the very first time, one of those planets within our Universe was discovered by the James Webb Space Telescope (JWST): LHS 475 b. This planet happens to be almost identical in size to Earth, with its radius determined to be 99% as large as our home planet’s. Although it’s in a fairly close, tight orbit around its parent star, that star is relatively cool: an old, stable, red dwarf star. As the planet — serendipitously aligned with its parent star from our perspective — transited across the face of its star, JWST got a chance to observe it, using the technique of transit spectroscopy to measure its atmospheric contents. But what it found was instead a disappointment, consistent with there being no atmosphere at all. It’s a remarkable step forward for science, but also, one that suggests that JWST’s “nightmare scenario” for exoplanet discovery might come true. Continued here

Tuscany's mysterious 'cave roads' Wildflowers grazed my legs as I hiked down from the volcanic-rock hilltop fortress of Pitigliano into the Tuscan valley below. At the base of the hill, I crossed a burbling stream and followed a winding trail as it inclined. All of a sudden, I was walled in. Huge blocks of tuff, a porous rock made from volcanic ash, rose as high as 25m on either side of the trench I found myself in.

Our strategic imperative was to make sure that the platform provided all the resources (…) that an online business would need to succeed.” Continued here

Is Santa Claus buried in Ireland? Amid green hilly pastures dotted with grazing sheep and a cemetery with graves dating back to the 13th Century, the ruins of St Nicholas Church tower over the family home of Maeve and Joe O'Connell. Among those resting eternally here are early inhabitants of the estate, parishioners of the church and – according to local legend – St Nicholas of Myra. Yes, the St Nick who inspired Santa Claus. Today, the O'Connells are the owners and sole (living) human inhabitants of Jerpoint Park, a 120-acre deserted 12th-Century medieval town located 20km south of the town of Kilkenny, Ireland. Located along the crossing point of the River Nore and Little Arrigle River, the settlement (formerly called Newtown Jerpoint) is thought to have been founded by the Normans, who arrived in Ireland around 1160 CE. According to a conservation plan compiled by Ireland's Heritage Council, the town flourished into the 15th Century, with archaeological evidence revealing homes, a marketplace, a tower, a bridge, streets, a mill, a water management system and nearby Jerpoint Abbey, which still stands today. But by the 17th Century, the town's occupants were gone, likely from a combination of violent attacks and a plague. Continued here

How we will use the Sun as a telescope to image alien cities Exoplanets are the hottest topic in astronomy right now. After the discovery of the first planet orbiting a Sun-like star in 1995, the field exploded, revealing that nearly every star in the sky hosts a family of worlds. Powerful advances in technology are just now starting to give us the capacities to detect biological or even technological markers in the atmospheres of these alien worlds.  That is all very exciting, but if we really want to know what is happening on planets many light-years away, we need to image them. High-resolution images of green-pocked continents could reveal the presence of life. High-resolution images of those same continents at night, dotted with the lights of cities, could reveal the presence of civilizations. Unfortunately, we lack the ability to create such images. They have been nothing more than a pipe dream for astronomers. But that is changing now. Continued here

Trimurti: Meet the "Holy Trinity" of Hinduism Hinduism is recognized as the world’s oldest living religion, with ancient scriptures dating back more than four thousand years. There is no single set of beliefs and practices that can be considered “correct” or “true” in Hinduism. Its major concern is that people make the journey in the first place, as the cycle of life provides the necessary lessons.  There are three principal deities to guide people through that cycle. The Hindu trinity is also known as the Trimūrti, Sanskrit for “three forms,” and it includes Brahma, Vishnu, and Shiva. Since these three gods are responsible for the creation, preservation, and destruction of the Universe, respectively, exploring Hinduism through the Trimūrti can be a key to understanding what makes Hinduism so enduring.  Continued here

5 biotech trends to watch in 2023 2022 saw some incredible scientific and technological breakthroughs, as well as some major medical breakthroughs — and 2023 is poised to follow up with more paradigm-shifting advances in the making. As the Deputy Director of Communications for Leaps by Bayer, I surveyed a brain trust of scientists, investors, and CEOs to learn which areas of biotech they are most eagerly watching this year. Here’s what they said. Cell and gene therapies encompass a wide range of approaches that attempt to treat disease at the cellular and genetic level. With cell therapy, patients’ cells are extracted, reprogrammed, and then injected back into their bodies, often with the goal of leveraging their own immune system to fight diseases like cancer. Of the approved cell therapies in the U.S., most focus on blood cancers because they have not yet shown success in treating solid tumors. One of the next goals in cell therapy is to improve efficiency by reprogramming patients’ cells in vivo — that is, inside their own bodies. Continued here

Mexico's 1,500-year-old unknown pyramids From a distance, the grey volcanic rock pyramids and their encircling stonewalls looked like something that Mother Nature had wrought herself. Located in Cañada de La Virgen (The Valley of the Virgin), an area about 30 miles outside the city of San Miguel de Allende in Mexico's central highlands, the stone formations blended into the arid, desiccated landscape like a diminutive mountain range. But as I got closer to the largest of the three structures, there was no doubt it was man-made. A staircase of identical steps, etched into the hard, dark rock, had clearly required a skilled mason's hand.

A secret site for the Knights Templar? In a hole in the ground beneath the Hertfordshire market town of Royston, dimly illuminated by flickering light, I was looking at a gallery of crudely carved figures, blank-faced and bearing instruments of torture.

"And there's Saint Lawrence. He was burnt to death on a griddle." Amid the grisly Christian scenes were Pagan images: a large carving of a horse, and a fertility symbol known as a sheela na gig, depicting a woman with exaggerated sexual organs. Another portrayed a person holding a skull in their right hand and a candle in their left, theorised to represent an initiation ceremony – a tantalising clue as to the cave's possible purpose. Adding to the carvings' creepiness was their rudimentary, almost childlike, execution. Continued here

Molecules, atoms, and their constituent particles did not readily reveal their secrets to the scientists that wrestled with the physics of atoms in the early 20th century. Drama, frustration, anger, puzzlement, and nervous breakdowns abounded, and it is hard for us now, a full century later, to understand what was at stake. What happened was a continuous process of worldview demolition. You might have to give up believing everything you thought to be true about something. In the case of the quantum physics pioneers, that meant changing their understanding about the rules that dictate how matter behaves. In 1913, Bohr devised a model for the atom that looked somewhat like a solar system in miniature. Electrons moved around the atomic nucleus in circular orbits. Bohr added a few twists to his model — twists that gave them a set of weird and mysterious properties. The twists were necessary for Bohr’s model to have explanatory power — that is, for it to be able to describe the results of experimental measurements. For example, electrons’ orbits were fixed like railroad tracks around the nucleus. The electron could not be in between orbits, otherwise it could fall into the nucleus. Once it got to the lowest rung in the orbital ladder, an electron stayed there unless it jumped to a higher orbit. Continued here S39 A Recently Discovered Gas Cloud Near Andromeda Stumps Astronomers With dozens of large telescopes scattered across Earth and some well above it, you might think we’ve pretty much discovered all there is to find in the sky. But this is, literally, too narrow a view. The recent discovery of a huge cloud of gas floating near the Andromeda galaxy—one of the most extensively studied objects in the heavens—is the latest proof that the sky still offers a vast amount of celestial real estate to sift through. This cloud has been hiding in plain sight for decades. And the best part is that its origin is a mystery. Continued here S24 The Maine lake full of sunken steamboats "A hundred years ago there were dozens of these things cruising around here," said a man who'd suddenly appeared next to me at the dock as I watched the approaching steamboat. He'd startled me out of my reverie, my gaze caught somewhere between the shimmer that dances across Moosehead Lake and the seaplanes taking off toward Mount Katahdin. I grew up in the US state of Maine at a smaller lake not far from here, and I spent many summers taking day trips to Moosehead Lake with my family. But this was the first time I boarded the historical Steamboat Katahdin, the last of a once-numerous fleet that used to ferry hordes of well-dressed elites from nearby train depots to the area's luxury resorts for their summer holidays.  Continued here S21 The Himalayas' ancient earthquake-defying design In 1905, a deadly earthquake rocked the landscape of Himachal Pradesh, an Indian state in the western Himalayas. Sturdy-looking concrete constructions toppled like houses of cards. The only surviving structures were in towns where the residents had used an ancient, traditional Himalayan building technique known as kath kuni. On a warm Tuesday afternoon, I was headed towards one of them: Naggar Castle, which was built more than 500 years ago as the seat of the region's powerful Kullu kings, and which remained standing, unscathed, after that calamity.  Continued here S49 The Best Tea Accessories for Sipping Steamy Beverages If you buy something using links in our stories, we may earn a commission.

Continued here S30 The mysterious Viking runes found in a landlocked US state "[Farley] spent the majority of her adult life researching the stone," said Amanda Garcia, Heavener Runestone Park manager. "She travelled all around the US, went to Egypt and went to different places looking at different markings." Faith Rogers, an environmental-science intern and volunteer at the Heavener Runestone Park, led me down a cobblestone path toward one of the 55-acre woodland's biggest attractions – which is also one of the US' biggest historical mysteries. We were deep in the rolling, scrub-forest foothills of the Ouachita Mountains in far eastern Oklahoma, and we were on our way to view a slab of ancient sandstone that still has experts scratching their heads and debating about the eight symbols engraved on its face.  Continued here S14 5 Ways to Outmaneuver Competitors Using Intellectual Property Plan ahead, startup founders! Copycats are never far behind a successful new product or service. Continued here S46 The sustainable brilliance of Indigenous design When human rights advocate Manu Peni returned to Papua New Guinea from abroad, he built a home for himself using modern techniques -- and promptly learned a harsh lesson on how the newest ideas aren't always the best ideas. Peni calls for us all to rethink who we consider experts, particularly when it comes to building in the face of climate change, showing how Indigenous wisdom must work in harmony with new science and technology if we want to create a sustainable future. Continued here S53 Riddle solved: Why was Roman concrete so durable? The ancient Romans were masters of engineering, constructing vast networks of roads, aqueducts, ports, and massive buildings, whose remains have survived for two millennia. Many of these structures were built with concrete: Rome’s famed Pantheon, which has the world’s largest unreinforced concrete dome and was dedicated in A.D. 128, is still intact, and some ancient Roman aqueducts still deliver water to Rome today. Meanwhile, many modern concrete structures have crumbled after a few decades. Researchers have spent decades trying to figure out the secret of this ultradurable ancient construction material, particularly in structures that endured especially harsh conditions, such as docks, sewers, and seawalls, or those constructed in seismically active locations. Continued here S23 Spain's ingenious fairy-tale houses Deep in Spain's north-western corner, the windswept Ancares mountains are dotted with centuries-old houses that look straight out of a fairy tale – or the Asterix and Obelix comic-book series – but that are cleverly suited to the harsh realities of this remote region. Known as pallozas, the round huts are made of stone and topped with a teardrop-shaped roof of rye straw. There are more than 200 scattered among Galicia's and Castile-León's rural villages, including Piornedo, Balouta, O Cebreiro and Balboa. Many of these homes were built 250 years ago, though their architectural roots stretch back millennia – some historians contend that pallozas are pre-Roman, an evolution of Celtic and Iron Age constructions. Continued here S50 2022 Wasn't the Hottest on Record. That's Nothing to Celebrate NASA and NOAA, two leading atmospheric science research agencies in the United States, have some ostensibly good climate news: Their twin annual analyses of global temperatures revealed today that 2022, like 2021, wasn't an all-time record-breaker. Instead, NASA says it tied with 2015 as the fifth-warmest year on record, and NOAA says it was the sixth. (The agencies use slightly different methodologies, and the difference between fifth and sixth place is just a hundredth of a degree Celsius.) Still, humanity remains on a dangerous trajectory because the past nine years have been the nine hottest since measurements began. "The heat waves this summer in Europe, the rainfall in Pakistan, the floods here and there and everywhere—they've been juiced by the overall global warming," says Gavin Schmidt, director of the NASA Goddard Institute for Space Studies and lead scientist of the agency's analysis. "It doesn't need to be the warmest year on record for these things to happen." Continued here S16 3 Lessons Learned During a Company Rebrand Rebranding can be complex and fear-inducing.

Continued here S47 Microbial Cocktails Are More Than a Gut Feeling In 2023, our understanding of the microbes that live inside the human gut will lead to new ideas for medicine. Today, we know that gut microbes help develop and sustain our immune system. They do that by producing high levels of three types of short-chain fatty acid molecules: acetic acid, propionic acid, and butyric acid (or butyrate). The last of these, butyrate, promotes the activity of immune cells called regulatory T cells, or T regs. These cells are specialists at turning off the activity of other immune cells, which is vital to keep the immune system from damaging the body. The other short-chain fatty acids also affect immune cells, as well as the cells of the gut lining, although these other processes are not as well understood.  This story is from the WIRED World in 2023, our annual trends briefing.

Now Comes the Hard Part The tech world’s biggest gadget show, CES, which took place in Las Vegas last week, looked a lot like a car show—and specifically an electric car show. Automakers and parts suppliers crowded the convention center halls with futuristic outlet-powered prototypes, sleek electric concepts, and software built to power that next generation of EVs. Yet the most vital electric auto project of the moment could hardly feel further from the limelight of Las Vegas. Drivers are embracing electric vehicles faster than industry analysts had expected, and sales are booming. But those e-wheelers will need somewhere to charge up, creating an infrastructure problem much less glamorous than the latest electrified sports car. Right now, some 90 percent of US electric vehicle owners can charge at home or at work. But convincing more Americans to buy electric is crucial (if not sufficient) to hitting climate goals. And more than a third of US residents live in apartment buildings, where installing a personal charger may not be an option. The US Department of Energy says there are just under 50,000 public electric vehicle chargers in the US, but one analysis projects that the country will need 495,000 if it hopes to hit state and federal goals to ban gas car sales by 2035. Each charger can cost more than $100,000 each to install.
