Phys.org / Innovative optical atomic clock could combine single-ion accuracy with multi-ion stability
For many years, cesium atomic clocks have been reliably keeping time around the world. But the future belongs to even more accurate clocks: optical atomic clocks. In a few years' time, they could change the definition of ...
Phys.org / Using magnetic frustration to probe new quantum possibilities
Research in the lab of UC Santa Barbara materials professor Stephen Wilson is focused on understanding the fundamental physics behind unusual states of matter and developing materials that can host the kinds of properties ...
Phys.org / Scientists design molecules 'backward' to speed up discovery
Every medication in your cabinet, every material in your phone's battery, and virtually every compound that makes modern life work started as a molecular guess, with scientists hypothesizing that a particular arrangement ...
Phys.org / A wild potato that changed the story of agriculture in the American Southwest
Starchy residue preserved in ancient stone tools may rewrite the story of crop domestication in the American Southwest, according to research led by the University of Utah.
Phys.org / Single enzyme found to control formation of immune cells critical for health
A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health found that an enzyme involved in protein ...
Phys.org / 2.6-million-year-old Paranthropus fossil expands early hominin range
In a paper published in Nature, a team led by University of Chicago paleoanthropologist Professor Zeresenay Alemseged reports the discovery of the first Paranthropus specimen from the Afar region of Ethiopia, 1,000 km north ...
Phys.org / Rye pollen's cancer-fighting structure revealed for first time
Nearly three decades ago, scientists found that a pair of molecules in rye pollen exhibited an unusual ability to slow tumor growth in animal models of cancer. But progress stalled for one seemingly simple reason: No one ...
Phys.org / Low-platinum catalyst could make hydrogen production cheaper
A new type of catalyst that uses five times less platinum than usual could help make hydrogen production more affordable in the future.
Phys.org / US forests store record carbon as natural and human factors combine
U.S. forests have stored more carbon in the past two decades than at any time in the last century, an increase attributable to a mix of natural factors and human activity, finds a new study.
Phys.org / Velocity gradients prove key to explaining large-scale magnetic field structure
All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale magnetic fields are ...
Phys.org / Fossil shorebirds reveal Australia's ancient wetlands lost to climate change
Flinders University paleontology researchers—with local fossil experts—have discovered how prolific shorebirds, including the Plains-wanderer, once lived across South Australia's South-East during wetter times up to 60,000 ...
Phys.org / How early cell membranes may have shaped the origins of life
Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This complexity allows cells ...
