First evidence that the genome can adapt to temperature changes

Researchers at the Universitat Autònoma de Barcelona are the first to have studied the effects of a heatwave on the genetic make-up of a species. The researchers have been monitoring the evolution of the fly Drosophila subobscura ...

Close look at iron-based superconductor advances theory

(Phys.org)—Cornell researchers have resolved a longstanding theoretical debate about the electronic structure of iron-based superconductors by directly observing it at the atomic scale. The work is reported in the Feb. ...

Dopants dramatically alter electronic structure of superconductor

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into "superconductors" able to carry electrical current with no energy loss-an enormously ...

Metamaterials provide active control of 'slow light' devices

LANL researchers and collaborators have made the first demonstration of rapidly switching on and off "slow light" in specially designed metamate­rials at room temperature. Metamaterials are assemblies of multiple individual ...

Scientists uncover how immune cells sense who they are

Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), a part of the National Institutes of Health, have demonstrated that DNA previously thought to be "junk" plays a critical role ...
