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 / Discovery of new fossils in Northwest Canada changes view of early animal evolution
Researchers have uncovered a remarkable fossil site in a remote part of Canada's Northwest Territories, offering unprecedented insight into the earliest evolution of complex animal life on Earth. Findings from the site represent ...
Phys.org / Coupled DNA nanopores control molecular traffic inside synthetic cell microreactors
Living systems such as cells rely on membrane pores and channels to transport molecules, exchange signals, and organize biochemical reactions. These functions emerge from dynamic interactions between molecular components. ...
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 ...
Medical Xpress / 'Pink noise' can help make anesthesia work better during surgery
In the brain, specific electrical waves are associated with different states of consciousness. For instance, delta waves—also known as slow waves—are especially prevalent during deep sleep, as well as during states of unconsciousness ...
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 ...
Medical Xpress / Scientists capture 'housekeeping' immune cells attacking live melanoma
Scientists at the Garvan Institute of Medical Research have captured, for the first time, "housekeeping" immune cells actively attacking and engulfing live melanoma cells—a discovery that could change the way we approach ...
Phys.org / AI-designed miniproteins switch key cell receptors on and off
G protein-coupled receptors, or GPCRs, sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies—from the ability ...
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 ...
Phys.org / Flint reveals changes in human mobility in the southern Pyrenees during the Upper Paleolithic
Analysis of more than 3,000 lithic artifacts from the Cova Gran de Santa Linya site (Les Avellanes-Santa Linya, Lleida) shows that anatomically modern human communities occupying the southern Pyrenees during the Upper Paleolithic ...
Phys.org / Multiplexed method reveals protein energy landscapes across 10 domain families
Northwestern Medicine scientists have developed a new experimental method to analyze conformational fluctuations in protein domains on a uniquely large scale, which may improve data-driven modeling, biology and protein engineering, ...
Medical Xpress / Sunscreen confusion puts more Americans at risk for Melanoma
Melanoma—the most serious form of skin cancer—doesn't just happen at the beach or in a tanning booth.
