Phys.org / 3D analysis of wrist ligaments reveals locomotion clues in human ancestors
When studying how fossil hominids moved, researchers usually analyze the morphology of bones—which is crucial for understanding the evolution of bipedalism—focusing mainly on muscle insertion sites. However, the potential ...
Phys.org / Enzyme disables bacterial toxin by cleaving key chemical ring structure
A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless. Malleicyprol is considered an important virulence factor of Burkholderia bacteria, which causes, among ...
Phys.org / Subsystem resetting: Researchers discover a new route to control phase transitions in complex systems
Researchers in the Department of Theoretical Physics at Tata Institute of Fundamental Research (TIFR), Mumbai, have discovered that instead of manipulating every component or modifying interactions in a many-body system, ...
Phys.org / Warmer ocean currents significantly destabilize ice sheets, driving their retreat
New research reveals how ocean warming triggered the large-scale retreat of the Northeast Greenland Ice Stream (NEGIS)—offering vital clues for understanding its modern-day vulnerability.
Phys.org / Data bias reduces reliability of AI models predicting antimicrobial resistance
Experts are increasingly turning to machine learning to predict antibiotic resistance in pathogens. With its help, resistance mechanisms can be identified based on a pathogen's genetics. However, the results should be viewed ...
Phys.org / Low-temperature greenhouse gas conversion: Direct current reveals charge-driven mechanism
Catalytic dry reforming of methane (DRM) offers a promising strategy for the sustainable utilization of greenhouse gases, CH4 and CO2. However, its practical application has long been hampered by severe catalyst deactivation ...
Phys.org / Subtle twist in materials prompts surprising electromagnetic behavior
Materials react differently to electric and magnetic fields, and these reactions are known as electromagnetic responses. In many solid materials, unusual electromagnetic responses have been known to only emerge when specific ...
Phys.org / Active thermal metasurfaces amplify heat signatures by a factor of nine
Light undergoes a unique phenomenon called superscattering, an optical illusion where a very small object scatters far more light than expected. This happens when multiple scattering modes overlap and interact, allowing tiny ...
Phys.org / Physicists push superconducting diodes to high temperatures
For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the team's result could help ...
Phys.org / GoMars model simulates 50-year Martian dust cycle
Mars is a dusty planet dominated by vast, dry deserts, with no easily accessible sources of liquid water. Much like on Earth, dust is lifted from Mars's surface by wind and rotating air columns, transported through the atmosphere, ...
Phys.org / How the ocean's most abundant bacteria diversify into ecologically distinct groups
A study led by the University of Hawaiʻi at Mānoa's Hawaiʻi Institute of Marine Biology (HIMB) has revealed critical new details about one of the ocean's most abundant life forms—SAR11 marine bacteria. Understanding ...
Phys.org / New fossil lungfish from Yunnan sheds light on critical stage of early vertebrate evolution
A research team led by Prof. Zhu Min—a member of the Chinese Academy of Sciences (CAS) and affiliated with the CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP)—has identified a new species of fossil ...
