Medical Xpress / How do GLP-1 agonists affect gene expression?
GLP-1s are building a reputation as "wonder drugs." First characterized for their ability to improve insulin release and treat diabetes, the drugs were later found to promote weight loss and improve cardiovascular health. ...
Phys.org / Cockroaches that eat each other's wings become exclusive partners
Scientists have discovered that, far from being solitary insects, some cockroaches appear to form an exclusive bond with a partner. And how do they get this relationship off the ground? By eating each other's wings.
Phys.org / Water-window X-rays without a synchrotron: How graphite flakes could shrink bioimaging tools
Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window." This new method holds promise in making bioimaging ...
Phys.org / Overshoot reshapes climate strategies—but the path to net zero remains unchanged
Temporary overshoot of global temperature targets—particularly the 1.5°C goal of the Paris Agreement—is no longer just a modeling concept. New research, published in Nature Climate Change and led by the Euro-Mediterranean ...
Dialog / Can we observe Earth-like exoplanets from our own planet?
Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge speaks directly to one of ...
Phys.org / Meet 'Tous'—an entirely new genus of mammal
Mammals are not especially diverse. Roughly 6,800 mammal species are known to exist, compared with about 8,800 species of amphibian, 11,000 species of bird and 12,500 of reptile. Yet when most people picture biodiversity, ...
Phys.org / A new 'molecular switch' for inborn immunity identified
Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or viral intruders. The PRRs forward the signals which results in the production of interferons, which ...
Phys.org / 'Nano-origami' reshapes liquid droplets into six-pointed stars
For the first time, researchers in France and Israel have observed how an emulsified liquid droplet can transform from a hexagon into a six-pointed star shape in response to rising temperature. Publishing their results in ...
Medical Xpress / Empathy's roots in parenting? Study in mice reveals brain circuits behind why we comfort others
Humans and animals share a remarkable capacity to sense when others are in distress and respond with comforting behavior. But the motivation for doing so, and why it sometimes breaks down, has been poorly understood. UCLA ...
Phys.org / Large area MoS₂ reduces energy loss in magnetic memory films
Scientists at the University of Manchester have discovered that placing magnetic films on atomically thin molybdenum disulfide (MoS₂) fundamentally changes how they lose energy, a finding that could bring 2D‑material ...
Medical Xpress / Better sleep could reduce anxiety in later life
As humans grow older, their emotional stability and sleep patterns can change significantly. For instance, some past studies have found that many older adults find it harder to manage negative emotions, experience higher ...
Phys.org / Brazilian fossil site yields smallest rhynchosaur fossil ever recorded
A study published in the Journal of Systematic Palaeontology describes the smallest rhynchosaur fossil ever recorded from the Brazilian Triassic, with the reconstructed skull only measuring around 2.5 cm (~1 inch). Additionally, ...
