Medical Xpress / Why the body's inflammatory alarm misfires in familial Mediterranean fever
Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease in which the body's own immune system overreacts to minimal or inappropriate stimuli, producing recurrent attacks of fever and painful inflammation. ...
Medical Xpress / D-serine accelerates gastric tumor growth by suppressing killer T cells
One of the crucial steps in cancer proliferation is evading killer immune cells. Cancer cells use a variety of signaling molecules to evade the immune system. Immune checkpoint inhibitor (ICI) therapy interferes with some ...
Medical Xpress / From growth to function: Gene helps human heart cells decide when to mature
Understanding how heart muscle cells stop dividing and acquire the characteristics needed to sustain lifelong cardiac function remains one of the greatest challenges in cardiovascular biology. Leveraging human induced pluripotent ...
Phys.org / Harvesting rainwater from rooftops could help cities stay cool and cut the number of heat wave days
Collecting rainwater from rooftops and using it to spray buildings during hot weather could help cities cut air conditioning use, lower urban temperatures and lessen the impact of heat waves, according to new research from ...
Phys.org / Molecular orbitals imaged in 3D, opening path to femtosecond videos
One of the most famous and intriguing results of quantum mechanics is the finding that fundamental particles, such as electrons, cannot be pinned down to one single location. Instead, a particle is described by its "wavefunction," ...
Phys.org / Nanowires restore key functions in aging T cells
For decades, scientists have accepted that the immune system naturally weakens with age. Georgia Tech biomedical engineer and Carl Ring Family Professor Ankur Singh wasn't convinced. Then the COVID-19 pandemic made the stakes ...
Medical Xpress / Newer AI models still reproduce racial and gender stereotypes in medicine
Flinders University researchers have evaluated two next-generation reasoning large language models (LLMs)—o3-mini and DeepSeek-R1—and found that when asked to describe fictional patients with common medical conditions, the ...
Phys.org / As urban tree shade shrinks, mortality rises
As trees disappear from urban neighborhoods, lives may be lost with them. In a new study, Northwestern University scientists tracked death rates and fluctuations in tree canopy cover across an 11-year period in Chicago. They ...
Phys.org / Ancient armored fish that narrowly avoided meteorite strike reveals life before Earth's largest mass extinction
A rare fossil discovered near South America's largest known meteorite crater has been named a new species. Initially mistaken for a frog by locals, Leolepis matogrossensis is actually a species of ancient ray-finned fish—the ...
Medical Xpress / Why do people's pupils dilate when they're surprised? Researchers explain
When people encounter new information that challenges their expectations, their pupils are likely to dilate. This physiological response is a sign that something is happening in the brain to help the person adapt to the new ...
Dialog / How to keep the Earth habitable when the sun dies
In a billion years, the sun will start to run out of fuel and expand to become a red giant. Earth's oceans and atmosphere will be burned away, and Earth will likely be engulfed by the sun altogether. The sun will then shrink ...
Medical Xpress / Cells in breast tumor microenvironment may reveal who benefits most from hormone treatment
The types of cells in the microenvironment of a breast tumor may affect how well the hormone therapy tamoxifen works over the long term. A study from Karolinska Institutet, published in BMC Medicine, shows this. The findings ...
