Phys.org / Experimental drug turns cancer's favorite fuel against it
Cancer cells have a voracious appetite for sugar—using it to fuel their rapid growth. This is why many scientists have tried to develop drugs that block cancer cells' metabolism by cutting off their sugar supply.
Medical Xpress / Researchers discover immune 'off switch' used by cancer cells
Mayo Clinic researchers have identified a protein that cancer cells use to shut down the body's immune response, a discovery that could help scientists develop new treatments that make cancer immunotherapies more effective.
Phys.org / Little-known protein helps the body restrain scar-forming signals
U.K. and U.S. scientists have uncovered an important piece of the puzzle in the signaling pathway that causes damaging scar tissue to build up in the body, raising hopes for future treatments. A team from the University of ...
Phys.org / How the 'fecal revolution' changed Earth's ecosystems
An international study led by Flinders University has found a fertile area of inspiration to explain an important step in evolution—and it's a whole lot of poop. The new study describes the "fecal revolution" to explain a ...
Medical Xpress / New brain model suggests how regional chemistry shapes large-scale neural activity
Researchers have developed a computer model of the human cortex that links its microscopic chemistry to its brain-wide patterns of activity, providing new evidence that regional differences in receptor density help shape ...
Medical Xpress / A hands-on approach to distance medicine
Dr. Pijuan Yu sits at his lab station, focused on the task at hand. He is feeling for a lump. The glass wall to his right reveals other students and researchers as they pass, but his attention remains steady. Two rubbery ...
Phys.org / Microbreaks key to boosting energy and motivation at work, study finds
Employees who incorporate microbreaks alongside work-related strategies into their workday are more motivated and energized, University of Queensland research has found.
Phys.org / 3D DNA mapping in rare immune cells reveals new genes linked with autoimmune disease risk
Our DNA is often pictured as a simple spiral, like a piece of rope held taut. But inside cells, it folds into a complex three-dimensional structure, with 2 meters (6.6 feet) of DNA scrunched like a headphone wire in a pocket. ...
Medical Xpress / A 'molecular switch' that heals the gut—and that colorectal cancer hijacks to spread
Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of ...
Tech Xplore / AI models nearly erase female characters when they write kids stories about animals
Last year, Melanie Walsh, a University of Washington assistant professor in the Information School, wrote an article examining how 300 popular children's books gendered their animal characters. Of the 13 most common animals, ...
Medical Xpress / What's in kratom products? Tests find 85% conflict with labels
What's listed on a kratom product label may not tell the full story. Researchers in the University of Florida College of Pharmacy have found that commercially available kratom products, including many kratom-derived products, ...
Phys.org / Electrostatic nanocorral offers new control over charged excitons and quantum light
Researchers created an electrically tunable quantum nanoscale corral that traps charged excitons and enables precise electrical control of tiny light sources, including their brightness, color and quantum states, the team, ...
