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.
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 ...
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 ...
Medical Xpress / Severe COVID-19 reactivates dormant viruses, study finds
Chronically infecting viruses—such as Epstein-Barr virus, cytomegalovirus (CMV) and herpesviruses—are common and often innocuous and asymptomatic. However, emerging evidence suggests their reactivation may contribute to autoimmune ...
Medical Xpress / Your personality changes more across your life than you think, according to new study
Personality traits have long been seen as set in stone, with many believing they stop changing once we reach adulthood. A recent study, however, challenges this long-held belief, suggesting that personality changes far more ...
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 ...
Phys.org / New models shed light on how an exotic phase of hydrogen in Earth's core may behave
While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, scientists suspect it makes ...
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 / Brittany burial mounds may hide human-shaped stones as Coëby cemetery mystery deepens
For archaeologists, the Coëby cemetery in Brittany, France, is a gold mine for research. It contains several prehistoric stone monuments and earth mounds. In a new study of two unusually large mounds, scientists may have ...
Tech Xplore / These 3D-printed objects can tell you if they're being used properly
Imagine a bottle of hazardous chemicals sitting on a laboratory shelf that changes its appearance to alert scientists that its lid is not properly secured, potentially preventing a dangerous spill.
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, ...
Phys.org / Adding an AI tool to Google Earth shook our trust in maps that has been centuries in the making
Throughout the 18th and 19th centuries, Europe's cartographers traded on their reputation for accuracy and detail at a time of huge societal change. But as demand grew for increasingly detailed maps of the world to support ...
