Traces of Toxic Industrial Chemical Found in U.S. Air for the First Time

Americans’ air is teeming with all sorts of known toxin pollutants—now scientists have found a new one to add to the list. Researchers at the University of Colorado Boulder detailed their discovery in a study published earlier this month. They sampled agricultural sites in Oklahoma and found clear traces of medium-chain chlorinated paraffins (MCCPs) in the surrounding air. The health effects of MCCPs on people are still being studied, though countries are already planning to debate whether thes

Scientists in Antarctica Detect Deep-Earth Signals That Defy Known Physics

A balloon-borne experiment over Antarctica, designed to detect cosmic radio waves, has instead picked up bizarre signals that appear to be coming from deep within the ice. These signals challenge our current understanding of particle physics, scientists say. The Antarctic Impulsive Transient Antenna (ANITA) experiment consists of radio antennas flown on NASA balloons 19 to 24 miles (30 to 39 kilometers) over the surface of Antarctica. In recent years, the detector has recorded radio pulses that

I Took a Quick Tour Through Longevity Culture. Here's What I Learned About Reverse Aging

I'm standing in a drafty room with several hundred people in London's Truman Brewery, all of us shaking our hands above our heads, woo-wooing our way to the end of another day at SXSW. I won't lie –– I'd hoped something like this would happen at some point during the week. Weird, offbeat moments such as this really separate a fun conference from a boring one. This particular moment is a mini taste of a "longevity rave" –– an event style that's popping up around the world, run by those who belie

How the first electric grid was built

The Linear No Threshold model says that there is no safe level of radiation exposure. There is overwhelming evidence it is false, yet it inspires the ALARA principle, which makes nuclear power unaffordable worldwide. Read the lead article from Issue 19 of Works in Progress. We’re hosting a Stripe Press pop-up coffee shop and bookstore on Saturday, June 28, in Washington, DC. RSVP here if you can make it.

Astronomers Just Solved the Mystery of the Universe’s Missing Matter

Decades ago, astronomers estimated that “ordinary” matter (basically everything that isn’t dark matter or dark energy) makes up 5% of the universe. There was just one problem—they had no idea where most of it was. Astronomers from the Center for Astrophysics Harvard & Smithsonian (CfA) and the California Institute of Technology (Caltech) have tracked down the universe’s “missing” matter. Fast radio bursts (FRBs) indicate that over three-quarters of ordinary matter, officially called baryonic ma

Sam Altman Says "Significant Fraction" of Earth's Total Electricity Should Go to Running AI

During a recent public appearance, OpenAI CEO Sam Altman admitted that he wants a large chunk of the world's power grid to help him run artificial intelligence models. As Laptop Mag flagged, he dropped that bomb dropped during AMD's AI conference last week after Lisa Su, the CEO of the hosting firm who counts Altman as a client and friend, mentioned ChatGPT's recent outages. Though OpenAI hasn't revealed the exact causes of its massive June outage, there's a good chance it had to do with runni

Salesforce study finds LLM agents flunk CRM and confidentiality tests

A new benchmark developed by academics shows that LLM-based AI agents perform below par on standard CRM tests and fail to understand the need for customer confidentiality. A team led by Kung-Hsiang Huang, a Salesforce AI researcher, showed that using a new benchmark relying on synthetic data, LLM agents achieve around a 58 percent success rate on tasks that can be completed in a single step without needing follow-up actions or more information. Using the benchmark tool CRMArena-Pro, the team a

Alta raises $11M to bring ‘Clueless’ fashion tech to life with all-star investors

Throughout her years working in technology, Jenny Wang, 28, always found herself stumbling back to one idea — a personal styling agent to help users decide what to wear and buy based on their budget, lifestyle, weather and calendar. She has tried to build such a product numerous times in the past, “but the AI technology was not yet mature enough,” she told TechCrunch. That’s changed so a few months ago she announced the launch of her dream company, Alta, followed by the announcement today of an

How Mixtape reminds us that your mixtapes were your life | Johnny Galvatron interview

It took Johnny Galvatron and his small team of neophytes six years to make The Artful Escape, a musical narrative game that debuted in 2021. With Mixtape, the team has been working on it for about two years. Annapurna Interactive published the game from Galvatron, a former star from the Australian band The Galvatrons, even though it focused on a somewhat cursed genre of music games. It did well enough for Annapurna, despite its recent troubles, to publish Galvatron’s second game. With Mixtape,
