Phys.org / Dynamic surface reconstruction explains how copper sulfide catalysts tune CO₂ reduction
Copper sulfide (CuS) catalysts continuously reconstruct their surface during electrochemical CO2 reduction, reports a study from the Institute of Science Tokyo, Japan. By uncovering the mechanism behind the dynamic surface ...
Phys.org / Unusual superconductivity could emerge in valley-imbalanced rhombohedral graphene
Superconductors are materials in which electrical current flows with a resistance of zero, typically below specific temperatures. In conventional superconductors, this state of matter emerges when two electrons bind together ...
Phys.org / Loud snoring—simulation reveals the physical mechanism that keeps so many of us awake at night
Anyone who has had to share a room—or worse, a bed—with a loud snorer knows the effect unchecked snoring can have on sleep, sanity and emotional stability. An entire industry of products, technologies and treatments claims ...
Phys.org / Why Korean 'aegyo' speech sounds cute: Adults raise vocal resonances to sound younger and smaller
In Korean, the term "aegyo" denotes a playful cuteness put on by adults to win someone's affection, typically in romantic contexts. This is usually accomplished with bashful expressions or a childlike manner of speaking sometimes ...
Phys.org / Double spiral inside narwhal tusks may explain their resistance to bending
The narwhal's impressive tusk has long been the subject of myths. In the Middle Ages, they were sold as unicorn horns believed to possess magical powers. Now, an international team of researchers led by Aarhus University ...
Phys.org / Distinct neurons drive mice's social sounds and squeaks
Mice use almost completely distinct sets of neurons for their two different types of vocalizations—the squeaks they produce when in distress or fighting and the whistle-like ultrasonic vocalizations they use when communicating ...
Phys.org / 'Snooping' on dolphins offers acoustic clues to hotspots for food and friends
For dolphins, the ocean is a world of sound. Their whistles carry social information, helping them communicate and stay connected, while echolocation—rapid-fire clicks—functions like underwater sonar, helping them navigate ...
Phys.org / Long-range magnetic interactions govern how a ferrimagnet approaches its phase transition
Close to a phase transition, very different materials can follow the same mathematical rules. The concept of universality, which groups seemingly distinct systems based on their common properties, was developed to describe ...
Phys.org / Tomato roots reveal hidden steps in 400-million-year-old fungal partnership
Scientists at VIB and Ghent University have produced the first high-resolution, cell-by-cell map of how tomato roots respond to colonization by arbuscular mycorrhizal fungi. These ancient fungal partners help plants absorb ...
Phys.org / Each degree of warming could add a month of intolerable heat for 1 billion people
The threat that rising temperatures fueled by climate change pose to the health of older people has been dramatically underestimated, according to a U.S. modeling study published Tuesday.
Phys.org / Drier soils may turn late summer into prolonged extreme heat
The summers of recent years have been hot, but not unusual from a meteorological perspective. According to researchers at Leipzig University, though, the next extreme summer would far exceed anything we have experienced so ...
Phys.org / Ancient Egyptian tomb shows how burial trends changed over hundreds of years
The Theban Necropolis, opposite Luxor, consists of more than 400 tombs. In a new Frontiers in Environmental Archaeology study, researchers in Spain examined part of one of these tombs—chamber three in tomb TT 209—to reconstruct ...
