Medical Xpress / Brain activity patterns may 'tag' experiences for later memory-making during sleep
The brain may "tag" experiences during learning to better consolidate memories of them during sleep, according to a study published Aug. 27 in the journal PLOS Biology by Dan Denis from the University of York, United Kingdom, ...
Medical Xpress / Cancer is quantum: Studies show cancer cells may occupy limited, shared states like quantized energy levels
Andrea Califano began his career as a physicist. But that's not why he's now calling cancer a quantum disease. "We're really just following the data," says Califano, the Clyde '56 and Helen Wu Professor of Chemical Biology ...
Phys.org / Parasitic plants act like genetic engineers by stealing and remodeling useful genes
Many plant species parasitize other plants by latching on and taking the nutrients their hosts need to survive. But sometimes, plants steal more than nutrients; they take genes.
Phys.org / Beyond the Petri dish: Testing tomorrow's drugs in human blood
The COVID vaccine is perhaps the first thing many people think of when they hear about mRNA-based drugs. Small packages of genetic material are sent into the body, prompting cells to produce useful proteins in the fight against ...
Phys.org / Venus's mysterious clouds may hide an exceptionally strong light absorber
Venus appears pale yellow in visible light, but ultraviolet images reveal dramatic dark and bright patterns moving with the planet's upper sulfuric acid clouds. Scientists have known about these markings for roughly a century, ...
Phys.org / Using AI to thwart election misinformation
Election rumors, such as unverified accounts of voter fraud, have run rampant in the U.S. in recent years. Powered by the speed of social media and artificial intelligence (AI), it can be hard for people to know what messages ...
Medical Xpress / Chronic pain is reflected in the folds and grooves of the cerebral cortex
Persistent pain often has no clear cause. However, studies show measurable differences in the structure and activity of the brains of those affected. This might explain why they experience chronic pain. "Many of our study ...
Phys.org / 'Like uprooting tree stumps'—pulling nanoscale anchors creates tiny pores that could speed biosensor manufacturing
A new manufacturing method could help move the production of nanoscale sensors from specialized fabrication facilities to conventional semiconductor manufacturing plants.Publishing in Science Advances, researchers from KTH ...
Medical Xpress / Heart capillaries may build natural bypasses for blood flow after heart attacks
The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart attack, this passage becomes blocked, usually when a blood clot forms on plaque in a coronary artery ...
Tech Xplore / Six-legged robot learns to walk from a stick insect
Do you ever see an ant skittering across your kitchen counter and wonder how this little bug overcame all the obstacles in your home just to get there? Insects use their tiny nervous systems to walk with surprising dexterity—a ...
Tech Xplore / Forged by fire, frozen for fuel: Thermal shock advances green energy
As the global push for cleaner energy intensifies, solid oxide fuel cells have emerged as a promising option. They turn hydrogen or other renewable fuels directly into electricity and heat without combustion, eliminating ...
Phys.org / Emperor penguin colonies reveal decades-long resilience and flexible breeding sites
With their charming waddles, heat-conserving huddles and tuxedo-like plumage, emperor penguins are among the world's most recognizable animals. Recent satellite surveys estimate that hundreds of thousands of the flightless ...
