Medical Xpress / Macrophage 'molecular scissors' may drive obesity-linked inflammation and metabolic damage
Imagine the body's immune cells as a neighborhood cleanup crew. When all is healthy, macrophages roam tissues, clearing away cellular debris and helping maintain order. But obesity can turn these normally protective cells ...
Medical Xpress / New fibroblast state reveals how lung tumors may suppress immune defenses
Researchers at Columbia University have identified a previously unknown population of fibroblasts that may protect lung tumors from immune attack. The work, published in Nature Immunology, illuminates a previously unknown ...
Phys.org / New study reveals how space rocks become meteorites
What happens to a space rock as it falls through Earth's atmosphere and becomes a meteorite? By studying 75 meteorite falls captured on video and in photographs, researchers identified seven distinct phases in the journey ...
Phys.org / How chromosomes find their partners
For a long time, so-called satellite DNA was considered largely worthless. Now, ETH Zurich researchers have shown in fruit flies that these repetitive sections of genetic material act as a kind of barcode, enabling the correct ...
Phys.org / Wildlife trafficking spreads across social media, putting thousands of species at risk
Researchers monitoring online activity for six weeks in mid-2025 found primates, birds, snakes, frogs, orchids and many other wildlife groups advertised for sale across Facebook, Instagram, TikTok and YouTube. Wildlife is ...

Tech Xplore / Spy-device detector users miss nearly 60% of hidden gadgets
Consumer detectors sold to help people find hidden surveillance devices are often too difficult for typical users to interpret, potentially giving a false sense of security to those most at risk such as domestic abuse survivors, ...
Tech Xplore / Attackers bypass Windows security without physical access
Experts have shown that the most powerful security defenses in Windows 11 can be dismantled by an attacker who never touches the target computer.
Tech Xplore / Tailored surface vibrations to improve aerodynamic performance in passenger jets
A passenger jet soars across the sky at 640 mph (1,030 kilometers per hour), its wings pummeled with wind and boundary-layer turbulence, challenging the plane's operation and efficiency. Advancing research from Mahmoud I. ...
Phys.org / The superconducting gap of an ultrathin nickelate defies expectations
Superconductors are materials that carry electrical current with zero resistance below a specific critical temperature. In conventional superconductors, the transition to superconductivity generally occurs at very low temperatures.
Phys.org / How to CT scan a 400-pound crocodile
At 61, Bill had begun showing changes in his health—decreased appetite, weight loss and abdominal bloating. But his bloodwork was normal, leaving the cause of his symptoms unknown. The next step was clear: Bill should get ...
Phys.org / Bacteria from ancestral wheat microbiomes help protect plants against root rot fungus
In the journal npj Biofilms and Microbiomes, researchers from the Brazilian Agricultural Research Corporation (EMBRAPA) and the University of São Paulo (USP) describe the role of three bacteria in suppressing a soil-borne ...
