Snails get stressed: Invertebrate model sheds light on biological basis of anxiety
Anxiety, the psychological and physiological state characterized by an anticipation of potential threats and a heightened sense of vigilance, is regularly experienced by many humans worldwide....
Individual neurons in amygdala and hippocampus encode visual features that help recognize faces, study finds
Humans are innately capable of recognizing other people they have seen before. This capability ultimately allows them to build meaningful social connections, develop their sense of identity, better...
New method stores high-density methane in graphene-coated nanoporous carbon
Methane (CH4), one of the most abundant natural gases on Earth, is still widely used to power several buildings and to fuel some types of vehicles. Despite its widespread use, storing and...
Twisted trilayer graphene shows high kinetic inductance
Superconductivity is an advantageous physical phenomenon observed in some materials, which entails an electrical resistance of zero below specific critical temperatures. This phenomenon is known to...
Injury to specific brain connections could explain some people’s criminal behavior, study finds
Over the past decades, some lawyers have started using brain imaging scans as evidence during criminal trials, to provide a possible explanation for the criminal behavior of defendants. This was...
New passivation strategy improves scalability and efficiency of perovskite solar cells
Solar cells, devices that can convert sunlight into electrical energy, are becoming increasingly widespread, with many households and industries worldwide now relying on them as a source of...
Study explores genetic link between cannabis use and psychiatric disorders
Cannabis, also known as marijuana or weed, is widely consumed worldwide, whether for recreational or medicinal purposes. Over the past decades, the use of cannabis has been fully legalized or...
Turning tap water into hydrogen: New strategy lets PEM electrolyzers use impure water
In recent years, energy engineers have been working on a wide range of technologies that could help to generate and store electrical power more sustainably. These include electrolyzers, devices that...
A new approach to probing Landauer’s principle in the quantum many-body regime
Landauer's principle is a thermodynamics concept also relevant in information theory, which states that erasing one bit of information from an information system results in the dissipation of at...
How hippocampal place cells and synaptic plasticity contribute to the progressive acquisition of memories
The human brain is known to store various memories for long periods of time, progressively learning from new experiences and forming adaptive representations that ultimately guide...
