AI trained on millions of life stories can predict risk of early death
Data covering the entire population of Denmark was used to train an AI to predict people’s life outcomes Francis Joseph Dean/Dean Pictures / Alamy Stock Photo An artificial intelligence trained on personal data covering the entire population of Denmark can predict people’s chances of dying more accurately than any existing model, even those used in…
Life may be less chaotic than we thought, say physicists
According to a long-standing idea, life exists at the edge of chaos, meaning it is sensitive enough to respond to small environmental changes. But an analysis of processes that occur inside cells challenges the idea Source link
Cyanide in the ocean of Saturn’s moon Enceladus could be good for life
An illustration of NASA’s Cassini spacecraft diving through the plumes of Saturn’s moon Enceladus NASA/JPL-Caltech The plumes of water vapour erupting from the surface of Enceladus seem to contain hydrogen cyanide, which – perhaps counter-intuitively – is a sign that the the ocean that lies beneath the surface of this icy moon of Saturn could be…
How tiny red stars can test ideas about the origin of life
A survey of small, cool stars is helping to narrow in on the conditions that might set the stage for life beyond our solar system. A look at about 200 ultracool dwarf stars shows that they lack sufficient ultraviolet light intensity to have the potential to jump-start life, researchers report December 1 in the Monthly…
COP28: Why a climate adaptation deal is a ‘matter of life or death’
Collins Nzovu, Zambia’s minister of green economy and environment, speaking at COP28 Dominika Zarzycka/NurPhoto/Shutterstock The countries most vulnerable to climate change say the world must do far more to help them adapt to rising temperatures and extreme weather, even as it races to slash greenhouse gas emissions, in what has emerged as a key issue…

Photographer Kristina Varaksina travelled to the Republic of Karakalpakstan, an…
Having children earlier in life is genetically linked to dying younger
There seems to be a link between the age you have children and your lifespan Halfpoint Images/Getty Images People who are genetically predisposed to having children earlier in life are less likely to live to the age of 76, according to an analysis of more than 270,000 people’s genomes. Why we age is one of…
