Phys.org / Billions are going into fish passage projects, but planning methods can undercut results
Fish that split their lives between fresh and salt water often face obstacles getting back and forth. Dams and roads fracture river networks and interfere with traditional migratory routes, sparking concerns about fish health ...
Phys.org / Milky Way black hole's missing wind finally found after a half-century-long search
The hunt is over. After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way's central supermassive black hole, Sagittarius ...
Phys.org / 'Out-of-place' rocks reveal how a young ocean formed
Deep below the Tyrrhenian Sea offshore Italy, scientists drilled into what they thought would be dark mantle rock—and found pieces of granite that seemingly had no business being there. Those unexpected intrusions turned ...
Phys.org / Smarter land use could unlock biodiversity, climate and economic gains across 146 countries
National governments and multilateral institutions face difficult challenges reconciling environmental goals, such as biodiversity conservation and addressing climate change, with economic development goals. In a first-of-its-kind ...
Phys.org / Quantum shell structure reveals new rule for proton-neutron pairing inside nuclei
Nuclear physicists used a little magic in their latest experiment conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, and the result has revealed surprising new information about the ...
Phys.org / On-demand Arctic observations with low-cost balloon systems could sharpen local storm forecasts
Arctic communities are increasingly exposed to dangerous weather events due to climate change and rely on accurate weather forecasts. However, conditions in the lower atmosphere remain poorly observed in the Arctic because ...
Phys.org / DNA repair enzyme uses one-dimensional sliding to detect key sites, researchers reveal
DNA is the blueprint of the human body. However, tens of thousands of DNA lesions occur in our bodies every day. In particular, if "apurinic/apyrimidinic sites" (AP sites, damaged sites where one letter of DNA information ...
Phys.org / Why jellyfish can't rise to the surface
Using box jellyfish as an example, researchers from Kiel University show how the physics of density, not behavior or physiology, can prevent animals from reaching the surface even as they actively swim upward.
Phys.org / Measuring gravitational waves in a humming universe with a coordinate-free approach
Gravitational waves are tiny ripples in spacetime. Their first direct detection in 2015 marked a revolutionary moment in astronomy. Today, we have a thorough understanding of signals that travel far from their sources through ...
Phys.org / Easily overlooked small wetlands are a big source of global methane
Waterlogged land areas such as marshes, bogs and fens are the world's largest natural source of methane. Even the smallest of wetlands emit this powerful greenhouse gas. In a study from The University of Texas at Austin, ...
Phys.org / D&D-seq maps DNA-protein interactions in single cells with multi-omics compatibility
A new technology allows scientists to map, in single cells, the DNA binding sites of transcription factors and other regulatory proteins that control gene activity, according to a study led by investigators at Weill Cornell ...
Phys.org / Can fighting via text be good for a relationship?
Today, many of our social interactions are routed through technology: text messages, video calls, voice messages, emails and instant messaging apps. In romantic relationships, couples often use these methods to deal with ...
