Medical Xpress / Some tumors eliminate healthy neighboring cells to grow, study reveals
Chromosomal instability is a common feature in many solid tumors and is associated with greater aggressiveness. For years, its main contribution to cancer was thought to be driving the evolution of tumor genomes, causing ...
Phys.org / Short videos may hinder learning by fragmenting attention and memory, study finds
Recent technological advances and the introduction of new digital media platforms have dramatically changed how people learn and source information about topics that interest them. Some recent studies have found that while ...
Medical Xpress / How mechanical stress can accelerate bone destruction in periodontitis
Excessive bite force does not cause alveolar bone loss but significantly worsens it when combined with periodontitis, report researchers in a new study. While traumatic occlusion has long been suspected to exacerbate periodontitis, ...
Phys.org / Strange winds on seven hot Jupiters reveal strongest signs yet of exoplanet magnetic activity
A team of astronomers has found the strongest evidence yet that some planets outside our solar system may be magnetic. Using the European Southern Observatory's Very Large Telescope (ESO's VLT) and the Gemini North telescope, ...
Phys.org / Photoexcitation flips 2D moiré devices from metals to insulators in ultrafast test
Quantum materials, materials with properties that are governed by the laws of quantum mechanics describing many-body interactions, have proved promising for the development of various advanced technologies. Many of these ...
Phys.org / Extraordinary fossils solve a 500-million-year mystery: Bryozoans were there at the dawn of animal life
Bryozoans are tiny, filter-feeding colonial invertebrates that thrive in the world's oceans today, yet for decades their origins presented a puzzling gap in the fossil record. While nearly every other major animal group made ...
Medical Xpress / Creatine may supercharge immune cells that are key to fighting cancer
Creatine, the organic acid that is popularly taken as a supplement by athletes and bodybuilders, supercharges a critical class of immune cells that activate and prepare the body's key cancer-fighters, according to new UCLA ...
Medical Xpress / Major surgery may accelerate memory loss in 1 in 7 older adults
Going through surgery can take a significant toll on a patient's physical health and capabilities, especially if they are elderly. A recent study found that the effects extend far beyond mobility and pain management, as the ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Phys.org / Understanding Earth's hidden east-west symmetry could improve climate models
Earth is divided into two halves: the Northern and Southern Hemispheres. Both reflect equal amounts of sunlight (albedo) even though they have different landmasses and weather patterns, especially cloud distribution. Why ...
Science X / Local 'Little Red Dots' stay eerily steady for up to 15 years, puzzling astronomers
Astronomers have spent over a decade tracking a unique type of compact dwarf galaxy, which continues to surprise everyone. Known as the "Little Red Dots" for their small, red appearance, these local galaxies look much like ...
Medical Xpress / Poor sleep threatens health, society and the economy
An increasing number of people are suffering from sleep deprivation, difficulty falling asleep, or interrupted sleep—with consequences for health, society, and the economy. An international research team involving the Institute ...
