Phys.org / Ancient DNA suggests western farming reached Gansu without mass migration
A multidisciplinary study has answered key questions about how agricultural practices diffused into ancient Gansu from Eurasia, as well as described population movements and burial practices in the Gansu region thousands ...
Phys.org / Warming seas could shrink most mollusks by 2100, but some may grow
Research led by scientists at the University of Louisiana at Lafayette challenges a long-held assumption about the effects of climate change on marine life: Warmer oceans won't simply make animals smaller.
Phys.org / The Arctic melt season is a week longer now than it was in the 1980s, new research on sea ice trends shows
Relatively few people have been to the Arctic, and even fewer have set foot in Antarctica. Most people rely on imagination and the media to visualize these landscapes and the ways they are changing.
Phys.org / Electron spin unlocks magnetic control of hydrogen surface reactions
Chemical reactions at surfaces play a central role in many processes, including catalysis and materials synthesis. It is well known that the outcome of these reactions is influenced by the translational, vibrational and rotational ...
Phys.org / Satellites spot forest stress two years before bark beetle die-offs become apparent
Satellite measurements detected declining photosynthetic activity in Western U.S. forests two years before bark beetle mortality appeared in aerial detection surveys, according to new University of Utah-led research.
Phys.org / BESIII sets world's most stringent direct limit on Lambda hyperon electric dipole moment
The BESIII Collaboration, led by the Institute of High Energy Physics of the Chinese Academy of Sciences, has achieved the world's most precise measurement of the electric dipole moment (EDM) of the Lambda (Λ) hyperon using ...
Phys.org / Microbes—dead or alive—can be early indicators of soil health under regenerative farming
Researchers have demonstrated a series of biological tests that could serve as "proxies" for measuring how different regenerative agriculture practices could improve soil carbon—years before it would be possible to measure ...
Phys.org / First switchable graphene nanoribbon that twists on demand
Researchers at Nagoya University have built a graphene nanoribbon that can switch the direction of its twist using a natural solvent. Graphene nanoribbons are thin, ribbon-shaped structures made of fused carbon rings. Twisted ...
Phys.org / Permafrost melt could cost $261 billion in infrastructure damages, study suggests
A new study provides insight into the economic impact of melting permafrost on Arctic communities. Permafrost is ground that permanently remains below freezing for at least two consecutive years. Permafrost covers about 24% ...
Phys.org / 'Power of disorder' tames CF₄, a semiconductor greenhouse gas that can persist for 50,000 years
Among the gases used in semiconductor manufacturing, tetrafluoromethane (CF₄) is a greenhouse gas more than 6,000 times as potent as carbon dioxide.
Phys.org / Nanoscale multiferroic materials open the path to efficient magnetic memory technology
With the rapid spread of cloud computing, artificial intelligence and data centers, global energy consumption is rising to new heights. A promising way to reduce this burden is to develop memory devices that store information ...
Phys.org / Bacterial nanoplatform reprograms spleen immune cells to help prevent cancer recurrence
A research team led by Professor Yong Taik Lim at the SKKU Advanced Institute of Nanotechnology (SAINT), Sungkyunkwan University, have developed an engineered nanoplatform named t-SMC (trained immunity-mediated splenic myelopoiesis ...
