Global warming has picked up speed in the past decade, according to a new analysis from the Potsdam Institute for Climate Impact Research (PIK). By removing short term natural influences such as El Niño, volcanic eruptions, and solar cycles from ...

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a "nuclear metabolic fingerprint." Some of the enzymes gather around ...

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could .. ...

Exercise normally boosts the body's ability to use oxygen, a key marker of health and longevity -- but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how .. ...

Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16-30 found users were more than twice as likely to sleep five hours or less per night. Many of these products ...

Scientists have found a way to significantly boost "blue energy," which generates electricity from the mixing of saltwater and freshwater. By coating nanopores with lipid molecules that create a friction-reducing water layer, they enabled ions to ...

DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on Bornean fanged frogs shows the line between species can be blurry--an important challenge when deciding what wildlife needs .. ...

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria--the cell's energy generators--can actively pull .. ...

A prehistoric mass grave in Serbia reveals that more than 77 people--mostly women and children--were deliberately killed in a brutal act of violence about 2,800 years ago. Genetic evidence suggests the victims came from different communities, ...

Physicists have long struggled to unite quantum mechanics--the theory governing tiny particles--with Einstein's theory of gravity, which explains the behavior of stars, planets, and the structure of the universe. Researchers at TU Wien have now taken ...
