Medical Xpress / As GLP-1 drugs surge in popularity, bariatric surgery rates plunge across the US
For a very long time, bariatric surgery, in which doctors removed a portion of the stomach, was the standard procedure for helping patients lose weight and manage obesity, alongside metabolic disorders such as diabetes, high ...
Phys.org / Scientists improve knowledge on sea level rise—and confirm it has been accelerating since 1960
Sea level rise is a direct consequence of human-induced climate change: global warming. It is relentless and very hard to stop. It arises from human-induced warming and the consequential expansion of the ocean, plus the addition ...
Phys.org / Astronomers uncover why some solar eruptions die
A team of scientists has recorded one of the most detailed views ever of a failed solar eruption, a powerful blast from the sun that never broke free. Their work is published in the journal Nature Astronomy.
Phys.org / Debunking a core chemistry concept taught in classrooms everywhere
A new study has revealed that a core idea taught in chemistry classrooms around the world may be wrong. Dr. Edwin Johnson, Lecturer at the University of Newcastle, co-authored the paper published in the Journal of Chemical ...
Medical Xpress / Cracking the code of p53 fragility: Why the genome guardian is prone to failure
The protein p53 is often called the guardian of the genome for its central role in preventing cancer. Yet paradoxically, it is also one of the most frequently mutated and dysfunctional proteins in human tumors.
Phys.org / Overpopulation can impair fertility. A new study explains why
Scientists have reported it for decades: overpopulation can impair reproduction. Crowded chickens lay fewer eggs. Crowded mice have smaller broods. In humans, several studies have associated increased population density with ...
Phys.org / An explanation for the massive black holes the JWST found in the early universe
One of the most puzzling findings from the JWST's observations of the early universe is the size of black holes. According to our understanding of black hole growth, these early black holes are far more massive than expected. ...
Phys.org / A key science publishing platform is cracking down on AI slop
The pre-print website arXiv has announced that researchers who put their names to papers which included errors clearly generated by artificial intelligence (AI) will face a year-long ban and ongoing restrictions.
Phys.org / Chimpanzees reveal 69 socially learned behaviors, nearly doubling known cultural repertoire
Scientists have identified dozens of previously overlooked cultural behaviors in wild chimpanzees, suggesting that the great ape's culture extends far beyond complex skills like tool use. In a single community, they found ...
Medical Xpress / Why energy fades with age: Missing membrane lipid may destabilize mitochondria
Why do cells age—and why do we lose our energy and vitality as we get older? This question is one of the central challenges of modern biomedicine. The focus is particularly on mitochondria—tiny cellular organelles long known ...
Phys.org / Why meat-eating dinosaurs like T. rex evolved tiny arms
The evolution of tiny arms in several groups of meat-eating dinosaurs was likely driven by the development of strong, powerful heads, which were used to attack prey, according to a new study led by researchers at UCL (University ...
Phys.org / Neptune's mysterious moon Nereid may be original survivor of Triton's chaotic arrival
Neptune's far-flung moon Nereid may be the last of the planet's original companions that managed to survive a cosmic crash, scientists reported Wednesday.
