Scientists have given yeast a brand new ability – gaining energy from light. The technique was remarkably easy, the team says, and could not only help us understand evolution but make better beer and biofuel.
-
Saturn’s moon Enceladus continues to climb the list of best places to look for life beyond Earth. New NASA data has detected a molecule thought to be key to the origin of life, and suggests there’s more chemical energy for life to chow down on.

Meeting aliens rarely goes well for humanity in movies. Scientists have been practicing by trying to chat to whales in their own language – and judging by early results, we should probably beef up security around the Eiffel Tower and the White House.
-
Phosphorus – a key ingredient for life as we know it – was thought to be relatively rare in space. But now, astronomers have detected a surprising amount of the stuff on the fringes of the galaxy, suggesting life may be more common in the cosmos.

A 15-year project trying to build a synthetic yeast genome has hit a major milestone – yeast cells with more than 50% synthetic DNA for the first time. The team created synthetic versions of almost all its chromosomes plus a completely new one.
-
The best places to search for life beyond Earth aren’t planets like Mars – they’re icy moons like Europa. The case for life on this watery world just got stronger, as the James Webb Space Telescope has detected a fresh carbon source there.
-
The animal kingdom is home to all kinds of stories – even horror stories. Scientists at Brown University have now uncovered a creepy new zombie story involving worms that propagate by hack their shrimp host's genome to take control of their minds.
-
It sounds like a disaster movie: scientists recently revived worms frozen in the permafrost since the Ice Age. Now, these worms have been attributed to a new species, and seem to have passed down their incredible hibernation genes to modern relatives.
-
How small a canvas can evolution work on? Scientists have experimented with a synthetic lifeform designed to have the simplest possible genome, and found that given the chance it can evolve lost fitness back, showing that indeed, “life finds a way.”
-
A new discovery has boosted the chances of life soon being found on another world. NASA has announced the detection of phosphorus, the rarest element that’s essential to life, in the oceans of Saturn’s moon Enceladus.
-
Scientists have discovered evidence of a “lost world” of previously unknown lifeforms that inhabited Earth about a billion years ago. Fossilized steroids were identified in rocks all over the world, produced by a group called the "Protosterol Biota."
-
Scientists are conducting a long-term experiment on evolution to investigate how single-celled organisms could evolve into multicellular lifeforms. After thousands of generations, their yeast grew 20,000 times bigger and 10,000 times tougher.
