Phys.org / Scientists trace crop viruses back to the last Ice Age
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. According to a new international study published in Plant Disease, the ancestors ...
Phys.org / Neutrons reveal magnetic signatures of chiral phonons
Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University mapped magnetic signatures ...
Medical Xpress / Circadian rhythm drives metabolic dysfunction in fat cells, study finds
Northwestern Medicine scientists led by Joseph Bass, MD, Ph.D., the Charles F. Kettering Professor of Endocrinology and Metabolism and director of the Center for Diabetes and Metabolism, have discovered how disruptions in ...
Phys.org / The Black Death's counterintuitive effect: As human numbers fell, so did plant diversity
Between 1347 and 1353, Europe was gripped by the most catastrophic pandemic in its history: the Black Death. Killing many millions, the plague wiped out between one-third and a half of Europe's population.
Phys.org / Microbes hitchhiking on marine snow could limit how deep carbon sinks
In some parts of the deep ocean, it can look like it's snowing. This "marine snow" is the dust and detritus that organisms slough off as they die and decompose. Marine snow can fall several kilometers to the deepest parts ...
Phys.org / Astrophysicists trace the origin of valuable metals in space, from colliding stars to merging galaxies
Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a sudden flash of gamma ...
Phys.org / European Space Agency probing fireball that hit German home
The European Space Agency said it is investigating a fireball that streaked across the skies of Europe on the weekend before reportedly punching a football-sized hole in the roof of a German home.
Medical Xpress / Adult ADHD trial shows clinically relevant reduction in symptoms
A randomized controlled trial (RCT) published in Psychological Medicine demonstrates a significant and clinically relevant reduction in ADHD symptoms in adults using the digital therapy "attexis."
Medical Xpress / Cheek cells may provide clues to schizophrenia risk
A simple cheek swab could one day provide a quick and noninvasive diagnostic test for schizophrenia. A new study published in Science Advances has identified higher levels of two biological markers in the cheek swabs of patients ...
Phys.org / Engineered magnetic films follow graphene's equations for massless electron waves
The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers ...
Phys.org / New LVK catalog adds 128 gravitational-wave candidates, more than doubling detections
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...
Phys.org / Mapping 3D-super-enhancers with machine learning to pinpoint regulators of cell identity
Scientists usually study the molecular machinery that controls gene expression from the perspective of a linear, two-dimensional genome—even though DNA and its bound proteins function in three dimensions (3D). To better ...
