Phys.org / JWST may solve a 20-year mystery behind a rule-breaking gamma-ray burst
Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did ...
Phys.org / JWST reveals likely Type II supernova from when universe was only 2 billion years old
Astronomers using the James Webb Space Telescope have identified one of the most distant exploding stars ever confirmed. The supernova, SN 2023aeaf, was found at a redshift of 3.195—so far away that its light has been traveling ...
Phys.org / Old-growth tropical forests bear lasting legacy of ancient Maya civilization
Rainforests in Central America that have remained largely untouched by modern human activities could bear the invisible imprint of ancient Maya civilizations. New research has found that forest structure in Belize, such as ...
Medical Xpress / Immune cells may have a biological memory that makes weight loss harder after obesity
According to the World Health Organization, one in eight people lives with obesity. Yet despite numerous health education programs, books, articles and treatments, many individuals still struggle to lose weight once they ...
Medical Xpress / Rare antibodies with potential to combat alpha-gal syndrome identified
National Institutes of Health (NIH) researchers have discovered rare antibodies that could inform the development of an intervention for alpha-gal syndrome (AGS), an emerging tick bite-associated condition that can cause ...
Phys.org / Caterpillar twitches in an ultraquiet chamber help biologists understand how these insects hear without ears
In a quiet summer garden, a caterpillar perches on a branch, munching serenely on leaves. A moment later, it freezes. It senses danger—and just in time. From behind, a wasp approaches, sizing up its prey.
Medical Xpress / 3D atomic-level snapshots reveal ketamine binds to human opioid receptors
Ketamine, a drug approved for medical use in 1970 as a short-acting anesthetic, including during the Vietnam War for battlefield surgery, is still a pharmacological mystery. For a long time, scientists knew that ketamine, ...
Phys.org / In tune with nature: Human speech follows a rhythm that is also found in the animal kingdom
The temporal structure of speech rhythms resembles that of the communication signals of numerous animal species. This is shown by a study conducted by a research team from the Leibniz Center for General Linguistics (ZAS) ...
Phys.org / Saturn encounter may have set distant centaur on path to becoming a comet
More than 3 billion miles (4.8 billion kilometers) from Earth, an ancient icy object is slowly awakening. As it drifts inward through the solar system, the frozen body known as Centaur 450P/LONEOS has begun releasing gas ...
Phys.org / LEDs let archaeologists see the past in a new light
An archaeological excavation is a little like eating a layered cake: Once you have removed a layer, you cannot put it back. The problem becomes even trickier if two layers look almost exactly the same. Researchers from Aarhus ...
Phys.org / A snake-headed vessel hints at a mysterious Roman cult
The ancient Romans were a deeply religious and superstitious people, worshiping dozens of cults—some official and others secretive. One of these was dedicated to Sabazios, a deity from Thrace and Phrygia (regions spanning ...
Medical Xpress / How breakfast primes the response to the hormones that manage blood sugar
