Phys.org / Gnaw-y by nature: Researchers discover neural circuit that rewards gnawing behavior in rodents
Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical ...
Medical Xpress / Why anger feels close to fear: Brain charts emotion in a map-like way
It is well established in psychology that humans conceptualize emotions by features known as valence (the degree of pleasantness or unpleasantness) and arousal (the intensity of bodily reactions, such as rapid breathing or ...
Phys.org / Soil health index finds restored mangroves can near full function
Brazilian researchers have developed an index that can measure the health of mangrove soils at different stages. When applied to degraded, restored, and preserved areas, the index revealed that healthy mangroves, including ...
Phys.org / Telomere breaks provide new insights into chaotic chromosome mutations
Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on mutation processes that contribute to cancer and inherited genetic conditions. The study, led by ...
Phys.org / Scientists document Europe's first Jurassic lizard trackways in Asturias
The article presenting the research results was published online at the end of February in the journal Ichnos. The study focuses on two trackways (T1 and T2) preserved as convex hyporeliefs on the underside of a Late Jurassic ...
Phys.org / Scientists control 'free-flowing' electric currents with light
By controlling magnetic fields using light, a team of researchers led by NTU scientists has solved a long-standing challenge to precisely direct electric currents produced by quantum materials. Their findings unlock new avenues ...
Phys.org / Strange cosmic burst from colliding galaxies shines light on heavy elements
A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely ...
Phys.org / Electron microscopy maps protein landscapes that drive photosynthesis
Research led by scientists at Washington State University has revealed insights on how plants form a microscopic landscape of proteins crucial to photosynthesis, the basis of Earth's food and energy chain. The discovery provides ...
Medical Xpress / Movies reconstructed purely from mouse brain activity
Scientists have successfully reconstructed videos purely from the brain activity of mice, showing what the mice were seeing, in a new study led by University College London (UCL) researchers. The findings, published in eLife, ...
Phys.org / Hybrid synthetic strategy unlocks previously unattainable molecular architectures
The molecular-scale design of materials is one of the major frontiers in modern science. Flat, highly conjugated organic molecules are already used in advanced technologies such as chemical sensors, optoelectronic devices, ...
Phys.org / An interstellar comet packed with alcohol? What ALMA found in 3I/ATLAS
Comet 3I/ATLAS continues to make astonishing headlines, thanks to new findings from astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA). This new research reveals that 3I/ATLAS is packed with an unusually ...
Phys.org / Deep ocean microbes may already be prepared to tackle climate change
Deep-sea waters are warming due to heat waves and climate change, and it could spell trouble for the oceans' delicate chemical and biological balance. However, a study published in Proceedings of the National Academy of Sciences ...
