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 .. ...

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 ...

Engineers have discovered an unexpected link between two very different realms of physics: the behavior of electrons in graphene and magnetic waves in specially engineered materials. By designing a thin magnetic film with a hexagonal pattern of holes ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint "Lyman-alpha" light emitted by energized hydrogen, ...

A new brain-imaging study has revealed how ketamine produces its fast antidepressant effects in people with treatment-resistant depression. Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ...
