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 / Scientists harness quantum tunneling to boost heavy water production efficiency
A study by scientists at Hunan University introduces a new hydrogen isotope separation method that leverages proton quantum tunneling to produce heavy water, overcoming the key physical limitation faced by current methods ...
Phys.org / Chemical shifts help track molecules breaking apart in real time
When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane ...
Phys.org / Mining the dark transcriptome: Synthesizing the first potential drug molecules from long noncoding RNA
A team from University of Toronto Engineering is the first to synthesize long noncoding RNA (lncRNA) outside the cell—a new approach to drug discovery that has already yielded some promising anti-inflammatory molecules. ...
Phys.org / NASA finds extreme star collision in unlikely spot
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this ...
Medical Xpress / The timing of rewards plays a key role in learning, study finds
For almost a century, psychology and neuroscience researchers have been trying to understand the processes via which humans and other animals acquire new skills or learn to deal with specific situations. One well-known and ...
Medical Xpress / Real-time metabolic monitoring on a chip: What happens inside a cell can be measured instantly
In a significant advancement for lab-on-chip technology, IBEC researchers in the frame of the European project BLOC, have demonstrated the first integration of a benchtop nuclear magnetic resonance (NMR) spectrometer with ...
Medical Xpress / Study of 3 million Swedes links women's suicide risk to female relatives' attempts
A woman's suicide risk may be influenced by the suicidal intention of her female first degree relatives, with sex-specific effects of a shared familial environment and possibly other social factors having a key role, finds ...
Medical Xpress / Younger stroke survivors face greater concentration, mental health challenges—especially those not employed
Analysis of a large, nationally representative survey shows that stroke survivors under age 50 have more problems concentrating and running errands and experience more poor mental health days than older stroke survivors do. ...
Phys.org / Opening the path to high-efficiency hydrogen production without expensive precious metals
A research team has successfully designed and developed a proprietary non-precious metal oxygen evolution reaction (OER) catalyst featuring a layered structure optimized for anion exchange membrane water electrolysis (AEMWE) ...
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 ...
Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
