In the United States, over one-third of food is never eaten, and more food reaches landfills than any other material in the municipal solid waste stream. Wasting food wastes the labor and other ...

More than a week after a glacial collapse near the Langtang Lirung mountain peak set off devastating floods in Nepal and Tibet, sending a deluge of rocks, mud and water to the valleys below, forensic ...

Clues emerging from DNA could unlock the mystery of human ancestors that are missing from the fossil record yet present in the genes of people living today. Scientists found evidence years ago that ...

Researchers have used AI to uncover the DNA signature of a key genetic “switch” involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly ...

ATHENS, Ga. — University of Georgia researchers have developed a method to estimate the age of sharks by analyzing chemical alterations in their DNA. The scientific technique relies on predictive ...

The evolutionary tree that produced Homo sapiens might contain more knots than previously thought. Researchers have identified traces of two ancient hominin species in the DNA of modern humans. One of ...

In a new Science study, scientists read the family tree buried inside modern genomes and turned up “ghost ancestors” in every population on Earth that no fossil records can account for. But did our ...

Two mysterious human relatives left their genetic footprints in the modern human genome alongside the DNA of Neanderthals and Denisovans, underscoring the fact that our ancestors interbred with many ...
