Phys.org / Improved climate forecasts alone won't protect Africa's poorest farmers
As Africa prepares for the arrival of a powerful El Niño weather event, an international team of researchers led by the University of Sydney and Imperial College London has found that access to improved forecasts alone will ...
Phys.org / Luminescence dating pushes age of South Dakota's Mammoth Site back by more than 100,000 years
Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, ...
Phys.org / Gravitational-wave analysis narrows the search for black hole impostors
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that ...
Phys.org / Researchers pinpoint key early-universe measurement with record precision
An international team, including researchers from the University of Minnesota Twin Cities, has reached a major milestone in "precision cosmology" by measuring the amount of helium created in the universe's first five minutes ...
Phys.org / AI helps microscopes find the most informative nanoscale features in a sample
Researchers at the Department of Energy's Oak Ridge National Laboratory (ORNL) have developed an artificial intelligence framework that helps researchers use atomic force microscopes to identify important nanoscale features ...
Phys.org / A 1,000-fold longer charge lifetime helps organic catalyst produce solar hydrogen faster
Researchers from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with researchers from the Technical Institute of Physics and Chemistry of CAS, ...
Phys.org / AI automates 3D membrane mapping, matching manual results in a fraction of time
Cell membranes and the proteins within them control many vital processes and play a key role in health and disease. But studying them in 3D images of cells has so far meant slow, manual work. A team from Helmholtz Munich, ...
Phys.org / Why are the stars around our galaxy's black hole missing their companions?
A new study suggests that the young stars orbiting the Milky Way's central black hole may have a surprisingly ordinary origin. But the black hole's influence may be what makes their origin look more exotic than it really ...
Phys.org / Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios
Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme ...
Phys.org / Silicon nanosphere coatings deliver glossy, nonfading color on 3D surfaces
"Color coatings are expected to provide vivid color, brightness, gloss and long-term durability, yet no existing technology satisfies all of these requirements simultaneously," says Kobe University materials engineer Hiroshi ...
Phys.org / Human embryo base editing can reach all cells but causes unpredictable genetic changes
A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge techniques can accurately edit genes in human embryos—giving scientists indispensable tools for understanding ...
Phys.org / Physicists turn classical light into a quantum machine for information processing
Quantum computers promise to tackle problems that are extraordinarily difficult for today's computers. But there is a major obstacle: quantum systems are notoriously fragile. Noise, loss and even tiny disturbances can destroy ...
