Medical Xpress / New RNA vaccine strategy aims to build broader immunity against mutating viruses
New research by Malaghan's Connor Laboratory, published in PNAS, shows how directing the immune system toward conserved areas of the COVID virus and its many variants using RNA technology could be a significant step toward ...
Medical Xpress / The hidden role of a cell-cycle regulator in senescent cells that don't divide
In a tale of identities as divergent as "The Prince and the Pauper," a well-known cancer-causing gene also influences cells in a zombie-like state meant to prevent cancer.
Phys.org / How methylation sets a parasite in motion to invade host cells
Parasites such as Toxoplasma gondii and the malaria parasite Plasmodium falciparum depend on rapid, precisely controlled movement to complete their life cycles. To start moving, they must assemble actin filaments at their ...
Medical Xpress / Brain recordings hint at how AI reads facial expressions differently from us
The human brain can recognize a person's face and expression in less than a blink of an eye, but current artificial intelligence (AI) models, although fairly accurate at doing the same, use a different process than the brain. ...
Phys.org / AI model designs potentially stable protein sequences beyond those found in nature
A protein's function is determined by its structure, and structure—the way a protein folds—is determined by its sequence of amino acids, the building blocks of proteins.
Medical Xpress / Keto diet has greater health benefits than other popular weight-loss diets, according to clinical trial
A diet that severely limits carbohydrates but is high in fat has the greatest health benefits for people with obesity compared with a Mediterranean diet or a low-fat diet, according to a clinical trial published Aug. 27 in ...
Medical Xpress / Physical exams alone may not reliably diagnose pneumonia in children, national study finds
When a child has symptoms that could be pneumonia, doctors often listen to the child's lungs with a stethoscope to help make a diagnosis. But a new national study led by physician-scientists at Ann & Robert H. Lurie Children's ...
Medical Xpress / Implantable cardioverter-defibrillators may benefit certain younger patients with mild–moderate heart dysfunction
A more than a decade-long medical trial has opened the way for potentially life-saving treatment options for patients with mild-to-moderate heart conditions. Internationally recognized cardiac expert Flinders University Professor ...
Phys.org / Candida fungi can burst immune cells and shape-shift to evade immunity
Candida auris and Candida albicans are microscopic fungi that cause life-threatening human infections, killing almost a million people globally every year. The World Health Organization lists both species among the top four ...
Medical Xpress / A liver signaling pathway may explain why colorectal cancer weakens muscle and bone
Researchers at the University of Colorado Anschutz and Indiana University School of Medicine have identified a biological process that may help explain why colorectal cancer can cause severe muscle and bone loss, especially ...
Phys.org / Low oxygen could limit insects' uphill escape from climate warming
Reduced oxygen levels and air pressure at higher elevations may limit insects' ability to move upslope to escape a warming climate, with potential consequences for the essential services they provide, like pollination, according ...
Medical Xpress / Three shifting immune states in sepsis could explain why treatments miss their window
Researchers have mapped how the immune response in people with sepsis changes over time. The work, led by King's College London, could help pave the way for treatments that target the specific parts of the immune system that ...
