Medical Xpress / Catching cancer's earliest moments: How mutated cells transform their local environment so a tumor can develop
Scientists at Memorial Sloan Kettering Cancer Center (MSK) and their colleagues are shedding new light on a tumor's earliest moments—revealing how lung cells with cancer-causing mutations recruit accomplices from healthy ...
Medical Xpress / HEPA air purifiers may boost brain power in adults over 40
Using an in-home HEPA purifier for one month spurs a small but significant improvement in brain function in adults age 40 and older. That's the result of a new study we co-authored in the journal Scientific Reports.
Medical Xpress / COVID antiviral speeds recovery but doesn't reduce hospitalization in vaccinated patients, trials find
Paxlovid (nirmatrelvir-ritonavir) does not reduce hospital admissions or deaths in vaccinated adults at higher risk of severe COVID-19, despite helping them recover faster, according to results from two national trials published ...
Medical Xpress / MorphoGenie learns reusable cell features that could sharpen disease diagnosis
Cells contain a wealth of information about health and disease, but extracting that data reliably from microscope images remains a major challenge. Many important differences between healthy and diseased cells are too subtle ...
Medical Xpress / How an anti-inflammatory drug helps the heart after a heart attack
Every day, thousands of people worldwide suffer a heart attack, often leading to lasting damage to the heart muscle. Recent research from the University of Oslo suggests that targeting inflammation in the body helps protect ...

Medical Xpress / Hormonal chain reaction may shed light on the causes of reproductive disorders
Researchers at the University of Ottawa and the Institute of Hydrobiology of the Chinese Academy of Sciences have discovered a new role for reproductive hormone secretoneurin (SN) and, for the first time, explained how it ...
Medical Xpress / Molecular 'switch' that fuels cancer progression discovered
Researchers from the University of Cape Town's (UCT) Scientific Computing Research Unit (SCRU) have uncovered a critical molecular "switch" that drives the formation of cancer-associated antigens. The study, published in ...
Medical Xpress / How does imagination really work in the brain? New explanation upends what we knew
Your brain is currently expending about a fifth of your body's energy, and almost none of that is being used for what you're doing right now. Reading these words, feeling the weight of your body in a chair—all of this together ...
Medical Xpress / Biosensor works with blood samples to identify pancreatic cancer in early stages
Brazilian researchers have developed an electrochemical sensor that can detect pancreatic cancer in its early stages. The device identifies the biomarker molecule CA19-9, which is associated with the disease, at low concentrations ...
Medical Xpress / How the adult brain reuses an embryonic signal to balance persistence and change
A signaling pathway best known for shaping the brain before birth also helps govern how adults learn, adapt, and persist in their behavior, according to new research co-led by Andreas H. Kottmann, associate medical professor ...
Medical Xpress / Asphalt is everywhere, but is it bad for our health?
If you piled all of Phoenix's pavement into one spot, it would be enough to cover San Francisco four times over. Roads, parking lots, and other paved surfaces blanket a lot of land—an estimated 40% of Arizona's capital city.
