These Smoked Human Remains May be the Oldest Mummies Known to Science

Researchers have discovered what they believe to be the earliest evidence of artificial mummification known to science, pushing back the timeline for the burial ritual to far before the time of the ancient Egyptians. Hunter-gatherers in Southeast Asia who lived some 20,000 and 4,000 years ago buried their dead in tightly crouched or squatting positions. Not only that, but these communities also practiced a form of mummification that involved drying out the human remains over a fire, as research

Electromechanical reshaping offers safer eye surgery

A new, promising technique has the potential to replace laser surgeries in ophthalmologists’ offices in the future, for a fraction of the cost. Called electromechanical reshaping (EMR), the technique offers a gentler approach to correcting the cornea than Laser-Assisted in Situ Keratomileusis (LASIK), today’s gold standard for treating vision issues including nearsightedness, farsightedness, and astigmatism. The eye develops these and other conditions when the cornea’s curvature is off—too stee

How to Watch an Asteroid Fly Uncomfortably Close to Earth on Wednesday

An asteroid the size of a commercial airplane will skim past our planet on Wednesday, September 3. Asteroid 2025 QD8 has no chance of hitting Earth, but its brief proximity will allow scientists (and you!) a rare opportunity to observe a passing asteroid at very close range. The Virtual Telescope Project 2.0 will host a livestream of the flyby starting at 7:00 p.m. ET on Tuesday, September 2. This astronomical program, overseen by the Bellatrix Astronomical Observatory in Italy, uses remotely c

LASIK Without Lasers? Scientists May Have Found a Way

What if you could fix your damaged eye without having to shoot a laser at it? Scientists have potentially discovered a novel method of repairing the cornea, similar to LASIK, that wouldn’t require a laser or other invasive surgical tool. Researchers at Occidental College and the University of California, Irvine, created the technique, which aims to temporarily make the cornea malleable. In experiments with rabbit eyeballs, their method appeared to work while also leaving corneal cells alive. Mo

Scientists Testing New LASIK-Like System That Doesn't Use a Laser on Eyeball

Image by Valeria Blanc / Getty Images Treatments Researchers have come up with a potentially groundbreaking — and entirely laser-free — alternative to LASIK, a popular surgical procedure that uses high-power lasers to reshape the cornea to correct vision problems. During a meeting of the American Chemical Society, a team of scientists led by Occidental College chemistry professor Michael Hill showed off a new approach, called "electromechanical reshaping" (EMR), that uses small jolts of electr

The AI Industry Just Got Some Horrible News

For years now, big tech and its financial backers have been blowing past the warning signs that human-level AI — the theoretical technology with hundreds of billions of dollars riding on it — could turn out to be a pipe-dream, at best. Now, however, Wall Street appears to be yanking its money out of one of the largest datacenter providers in the game, possibly an early indicator that reality could be finally catching up to the massively hype-dependent AI industry. On Tuesday, datacenter and te

Cohere hires long-time Meta research head Joelle Pineau as its chief AI officer

Investors once saw Canadian AI startup Cohere as a promising contender to challenge OpenAI and Anthropic in the race to build frontier AI models, with its backers pouring roughly $1 billion on their bet on CEO Aidan Gomez, who co-authored a seminal paper on LLMs when he was a 20-year-old Google intern. But Cohere’s AI models have fallen behind the state-of-the-art, and its business hasn’t scaled like its competitors. Now, the company is bringing in a veteran research leader to revamp its AI ef

What’s Going On at Tesla? A Wave of Executives Is Heading for the Exits

What’s going on at Tesla? The electric vehicle manufacturer, navigating a challenging business landscape marked by increased competition and evolving consumer sentiment, also appears to be facing a significant internal crisis: a rapid exodus of top talent. Elon Musk’s group has now lost its 10th executive this year. The latest departure is Piero Landolfi, who announced his exit on LinkedIn after nearly nine years with the company. “After 8 3/4 years I have made the difficult decision to leave

Best Running Shoes for Women in 2025

Picking out a running shoe is a different experience than shopping for other types of footwear. For one, everyone has different preferences as far as style goes and their running needs. Some shoe brands are known to make shoes for specific types of running (trail, speed, daily), and you may notice some will market themselves as minimalist, maximalist or in-between sneakers. Running shoes, like walking shoes, can also be versatile enough to use for different activities. The only difference is tha

Italy's pizza detectives

What Your Nighttime Breathing Says About Your Health

For decades, sleep disturbance was a punch line: the cartoon dad snoring, the disgruntled partner burying their head under a pillow. But science is beginning to paint a less jovial picture. Sleep apnea—a relatively common disorder where breathing repeatedly stops and starts during sleep—is now being taken seriously as a potential biomarker for a host of major health conditions, from cardiovascular disease to Alzheimer’s, even anxiety and depression. “Sleep is just as important for health as die

Aeneas transforms how historians connect the past

Research Aeneas transforms how historians connect the past Share Copy link × Introducing the first model for contextualizing ancient inscriptions, designed to help historians better interpret, attribute and restore fragmentary texts. Writing was everywhere in the Roman world — etched onto everything from imperial monuments to everyday objects. From political graffiti, love poems and epitaphs to business transactions, birthday invitations and magical spells, inscriptions offer modern hist

Scientists Teach AI to Think About the Roman Empire

Historians don't know when the Ancient Roman text "Res Gestae Divi Augusti," a chronicle of Emperor Augustus's deeds, was first written, since these kind of epigraphs tend to not contain any written dates. Enter our hero Aeneas — not the mythological forefather of Rome, but a generative AI model that's been trained on Ancient Roman texts. According to The New York Times, the Aeneas AI pinpointed the date of the Augustus epigraph to around 15 CE, soon after his death in 14 CE. Aeneas, developed

Where are vacation homes located in the US?

As of 2023, the US has around 142.3 million housing units: roughly one home for every 2.4 people in the country. The vast majority of these homes – 127.5 million – are occupied. The remaining 14.8 million homes are vacant. Of these, around 4.8 million homes, or around 3.5% of the total, are vacant because they’re seasonal, or vacation, homes. I’ve spent a lot of time writing about patterns of housing and home construction in the US, but virtually none of it has been looking at vacation homes sp

Neanderthals Ate Maggots, Scientists Say

Modern humanity’s most famous cousins, the Neanderthals, may have had a clever, if unappealing, dietary trick for survival: maggots. Research out today posits these creepy crawly fly larvae provided Neanderthals an ample source of essential nitrogen and fat. Scientists at Purdue University, the University of Michigan, and others conducted the study, published Friday in Science Advances. Using both experimental and historical data, they showed that maggot-infused meat is rich in fat and nitrogen

The Download: gas and oil’s role in climate tech, and using AI to decipher ancient Latin

—Casey Crownhart After writing about Quaise, a geothermal startup that’s trying to commercialize new drilling technology, I've been thinking about the role oil and gas companies are playing in the energy transition. It’s becoming increasingly common in climate tech to see a startup join up with a bigger fossil fuel company in its field, like Quaise has with Nabors Industries, one of the biggest drilling firms in the world. This industry has resources and energy expertise—but also a vested inte

Google DeepMind's Aeneas model can restore fragmented Latin text

At its best, AI is a tool, not an end result. It allows people to do their jobs better, rather than sending them or their colleagues to the breadline. In an example of "the good kind," Google DeepMind has created an AI model that restores and contextualizes ancient inscriptions. Aeneas (no, it's not pronounced like that) is named after the hero in Roman mythology. Best of all, the tool is open-source and free to use. Ancient Romans left behind a plethora of inscriptions. But these texts are oft

Google DeepMind’s new AI can help historians understand ancient Latin inscriptions

To do this, Aeneas takes in partial transcriptions of an inscription alongside a scanned image of it. Using these, it gives possible dates and places of origins for the engraving, along with potential fill-ins for any missing text. For example, a slab damaged at the start and continuing with ... us populusque Romanus would likely prompt Aeneas to guess that Senat comes before us to create the phrase Senatus populusque Romanus, “The Senate and the people of Rome.” This is similar to how Ithaca w

Trump admin squanders nearly 800,000 vaccines meant for Africa: Report

Nearly 800,000 doses of mpox vaccine pledged to African countries working to stamp out devastating outbreaks are headed for the waste bin because they weren't shipped in time, according to reporting by Politico. The nearly 800,000 doses were part of a donation promised under the Biden administration, which was meant to deliver more than 1 million doses. Overall, the US, the European Union, and Japan pledged to collectively provide 5 million doses to nearly a dozen African countries. The US has

Local cuisine was on the menu at Cafe Neanderthal

Sixty thousand years ago, two groups of Neanderthals lived just a stone’s throw apart in what’s now northern Israel. But they had very different cultures when it came to food, according to a recent study. Archaeologist Anaëlle Jallon of Hebrew University of Jerusalem and her colleagues examined dozens of animal bones from both sites, looking for clues about Neanderthal meal prep. It turns out that something as mundane as the cut marks left by butchering an animal can reveal differences in ancien

Bitcoin is nearly double where it was a year ago. This is what's behind the run

Bitcoin traded around $116,000 on Tuesday, falling back from a historic surge that briefly sent the world's largest cryptocurrency past $123,000 for the first time. Even with the pullback, the cryptocurrency is still trading at nearly twice its level from a year ago. Unlike previous cycles, the record run isn't being driven by retail mania or meme-stock energy. This move is being powered by structural demand, shifting macro positioning and a wave of Wall Street adoption that's playing out in r
