Medical Xpress / Unexpected discovery reveals mechanism behind brain tumor development
When researchers at Lund University investigated how UM171, a molecule used to make blood stem cells multiply, works, they made an unexpected connection. The results provide new insights into how one of the most common malignant ...
Phys.org / Unexpected source of genetic diversity found in human sperm
Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development than previously thought. Published in Nature, researchers at the Wellcome Sanger Institute, the ...
Medical Xpress / Pre-cancerous blood cells may fuel disease risk by prematurely aging the bone marrow
Precancerous blood cells can actively reshape their surroundings, prematurely aging cells in the bone marrow to create conditions that favor their own growth and potentially increase the risk of blood cancer, according to ...
Phys.org / Researchers reveal the unique 'tagging' mechanism that guides the sleeping brain in remembering key thoughts
Why do we remember certain moments while forgetting others? Every day, our minds are bombarded with thousands of pieces of information, yet our brains have a limited capacity to consolidate these experiences into lasting ...
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 / XY or ZW? Gecko chromosomes reveal evolution's hidden playbook
Why do humans rely on XY chromosomes to determine sex, while birds use ZW—and many reptiles use neither, letting temperature decide instead? Sex determination is remarkably diverse across the animal kingdom. In genotypic ...
Phys.org / Heat-tolerant corals may be more vulnerable to disease
Corals that partner with heat-tolerant algae may be better equipped to survive warming oceans—but that resilience comes with an unexpected trade-off, according to a new study from Boston University published in Science Advances.
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 / Nanoscale transistors achieve lower contact resistance with stepwise evaporation method
Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received ...
Phys.org / How bacteria develop resistance to programmable antibiotics
Antimicrobial resistance is one of the greatest challenges facing modern medicine. A new class of programmable antibiotics known as asobiotics can be used to treat bacterial infections when classical antibiotics fail. A team ...
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, ...
Phys.org / Oxygen collisions reveal how quark–gluon matter approaches equilibrium
High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons ...
