Scientists created AI that could detect alien life — and they're not entirely sure how it works

Scientists have created an artificial intelligence (AI) program that can detect alien life in physical samples — though they aren't sure exactly how it works. The new machine-learning algorithm — trained using living cells, fossils, meteorites and lab-made chemicals — can distinguish between samples of biological and nonbiological origin 90%...

Alien life may evolve from radically different elements than human life did

Self-sustaining chemical reactions that could support biology radically different from life as we know it might exist on many different planets using a variety of elements beyond the carbon upon which Earth's life is based, a new study finds. On Earth, life is based on organic compounds. These molecules are...

Scientists are searching for alien signals at frequencies never studied before

Is there life beyond Earth? The question has turned out to be one of the hardest to answer in science. Despite the seemingly boundless expanse of the universe, which implies there's potential for abundant life, the vast distances between stars render the search akin to locating a needle in a...

World's 1st 'conversation' between humans and whales could help us talk to aliens someday, scientists claim

Humpback whale conversations provide valuable insight on how humans may one day communicate with life beyond Earth, new research claims. Researchers from the SETI Institute, University of California Davis and the Alaska Whale Foundation recently conversed with a humpback whale named Twain using an underwater speaker and recorded a humpback...

Seismic reading linked to 'alien technology' by Harvard professor likely came from a passing truck, study claims

Another study has cast doubt on a Harvard professor's claim that he discovered tiny metallic balls made by aliens at the bottom of the Pacific Ocean. In 2023, Avi Loeb, director of Harvard University's computational astrophysics center, claimed he had found several metallic spherules left behind by a meteor that...
