Researchers have developed a fish-like robot that shows how some species of modern fish are able to walk on land, and could help unravel how early vertebrates evolved similar abilities hundreds of millions of years ago.

Researchers from the University of Copenhagen have identified a previously unknown protein that may help explain how plants managed to colonize land more than 400 million years ago. The protein was studied in moss, and the new findings contribute to our understanding of plant evolution and life on Earth.

A new study identifies vgll3 as a key gene that promotes rapid growth and early reproduction while increasing the risk of aging and cancer later in life. The findings provide rare experimental evidence for the theory that evolution favors early-life advantages even at the expense of long-term health. Researchers say the discovery could open new paths for understanding, and potentially separating, the biological links between development, aging, and disease.
