Phys.org / Blue and fin whale sightings on the rise in the Southeast Atlantic
More than 40 years after the end of commercial whaling, new research reveals a recent increase in sightings of the world's two largest whale species in the southeastern Atlantic. The findings, published in the African Journal ...
Medical Xpress / Why brain cells learn better: NMDA receptor maps may explain memory-linked calcium flow
The human brain constantly adapts in response to experiences, forming new connections between neurons and reorganizing existing ones. The brain's ability to adapt in response to experiences is known as neuroplasticity.
Phys.org / Intensifying droughts may be pushing tropical forests toward a dangerous threshold
Tropical forests, often described as the lungs of the planet, may be edging closer to a dangerous threshold as droughts become more frequent and widespread across the world's humid tropics. New research suggests these ecosystems ...
Medical Xpress / Mental disorders have nearly doubled since 1990, now affecting 1.2 billion people worldwide
Nearly 1.2 billion people worldwide are living with a mental disorder, nearly double the number recorded in 1990. According to a new study, this stark rise has placed mental disorders as the leading cause of disability globally, ...
Phys.org / MeerKAT discovers 15 new millisecond pulsars in a well known globular cluster
Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest ...
Phys.org / Unusual nonlinear thermoelectric effect appears in chiral tellurium, confirming theoretical predictions
An unusual thermoelectric effect has been observed in the semiconductor tellurium by RIKEN physicists for the first time. This demonstration points to the potential of similar materials to be used in applications such as ...
Phys.org / Dual-atom fuel cell catalysts break single-peak rule, exposing two optima
Researchers have uncovered a new principle that could accelerate the development of cheaper and more efficient fuel cells by revealing how dual-atom catalysts behave during a key energy conversion reaction. The study, led ...
Phys.org / Climate catch-22: Cleaning up air pollution could speed key Atlantic current decline
It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts ...
Phys.org / Extraterrestrial life may be slipping past space missions, astrobiologists warn
Suppose there are signs of extraterrestrial life and we have not yet been able to detect them. What does that mean? In Nature Astronomy, researchers discuss the consequences of these so-called false-negative results. "We ...
Phys.org / eROSITA discovers a 'changing-look' Seyfert galaxy
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor ...
Science X / Across Bronze Age Sweden, carved footprints point to a ritual for turning social ties into stone
Etched into the ancient rocky outcrops of southern Scandinavia and large boulders left behind by retreating glaciers are footprints, also called podomorphic petroglyphs. Some are barefoot with every toe visible, while others ...
Medical Xpress / A brief kidney crisis in childhood can cast a long shadow over health for years afterward
Acute kidney injury (AKI) is a condition in which the kidneys suddenly lose their ability to filter waste from the blood. Developing within hours or days, AKI can cause dangerous waste accumulation and disrupt the body's ...
