Half-billion-year-old tunicate from western Utah “looks like it died yesterday”
OpenAI is back in the headlines with news that it is updating its viral ChatGPT with a new version called GPT-4. But when will this be available, how does it work and can you use it?
Artificial intelligence art generators train themselves on art pulled straight from the internet… but what happens when most of the art out there is now made by AI?
Humanity needs to eat less meat. Here are seven alternatives.
Would you eat a burger enriched with mealworms? Fake bacon sliced from a mass of fermented fungi? Milk proteins extruded by microbes? Maybe you already have. Dozens of companies are now banking on these alternatives to animal protein becoming a regular part of your diet.
Complexes formed from ‘nanobodies’ and an antiviral drug halt infection in its tracks.
A dynamic duo comprising an antiviral drug joined to an antibody fragment provides strong protection against the two main types of influenza that infect humans, according to research in mice.
Subtle shifts in stellar signals reveal pervasive waves from mergers of giant black ho
Scientists are learning how to cryopreserve living tissues, organs, and even whole organisms, then bring them back to life
The huge eruption of the Hunga Tonga–Hunga Ha‘apai volcano generated more than 2,600 lightning flashes per minute.
Freely accessible large language models have accelerated the pace of innovation, computer scientists say.
The craze for generative artificial intelligence (AI) that began with the release of OpenAI’s ChatGPT shows no sign of abating. But while large technology companies such as OpenAI and Google have captured the attention of the wider public — and are finding ways to monetize their AI tools — a quieter revolution is being waged by researchers and software engineers at smaller organizations.
Mock embryos created by multiple groups recapitulate developmental events beyond implantation

An MIT class exercise suggests AI tools can be used to order a bioweapon, but some are skeptical
A skull fragment and shin bone suggest that early modern humans might have passed through southeast Asia earlier than thought.
Researchers laboriously sifted through clay, bucket by bucket, using their fingers to hunt for bone fragments
For most of history, the only lights made by humans were naked flames. Daily life was governed by the times of sunrise and sunset, outdoor nighttime activities depended on the phase of the Moon, and viewing the stars was a common and culturally important activity. Today, the widespread deployment of outdoor electric lighting means that the night is no longer dark for most people—few can see the Milky Way from their homes. Outdoor lighting has many legitimate uses that have benefited society. However, it often leads to illumination at times and locations that are unnecessary, excessive, intrusive, or harmful: light pollution.
Data on shark populations in coral reefs raise concern and hope for recovery
Sharks and their relatives are some of the most threatened vertebrates on Earth, with approximately one-third estimated or assessed as threatened with extinction (1). This is a major problem because as predators that help keep the food web in balance, these animals play a variety of vitally important ecological roles (2) and in doing so help to keep healthy many ecosystems that humans depend on. Coral reefs provide homes for countless fish species that are vital for fisheries and are therefore an especially important ecosystem for humans—and one where the decline of shark populations seems to be especially acute
The technology developed by DeepMind that plays Go and chess can also help to write code.
An artificial intelligence (AI) system based on Google DeepMind’s AlphaZero AI created algorithms that, when translated into the standard programming language C++, can sort data up to three times as fast as human-generated versions.
“We were a bit shocked,” said Daniel Mankowitz, a computer scientist at DeepMind who led the work. “We didn’t believe it at first.”
Extensive flooding could have severe consequences for farming, health and the environment.
The 66-year-old Kakhovka dam on the Dnieper River in south Ukraine collapsed on the morning of 6 June after a suspected explosion, triggering a catastrophic humanitarian and environmental crisis.
At Brooklyn’s Green-Wood Cemetery the living get as much attention as the dead. Groundskeepers maintain the 478-acre historic landmark as an arboretum and habitat for more than 200 breeding and migratory bird species. But many visiting wildlife lovers aren’t interested in those native birds. They’re at the entryway, their binoculars trained on the spire atop its Gothic Revival arches. They’ve come to see the parrots.
When dangerous heat waves hit cities, better risk communication could save lives
Exposure to extreme heat can damage the central nervous system, the brain and other vital organs, and the effects can set in with terrifying speed, resulting in heat exhaustion, heat cramps or heatstroke. It also exacerbates existing medical conditions such as hypertension and heart disease and is especially perilous for people who suffer from chronic diseases. The older population is at high risk, and children, who may not be able to regulate their body temperatures as effectively as adults in extreme conditions, are also vulnerable.
