Phys.org / Avalanche cracks may appear globally supersonic while remaining locally subsonic
Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific ...
Phys.org / Simulations hint at a hidden population of companionless black holes
So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Medical Xpress / Erectile dysfunction drug used to treat enlarged prostate symptoms may raise glaucoma risk
An erectile dysfunction drug that is also used to treat symptoms, such as sudden urgency and frequency, associated with an enlarged prostate in men may heighten the risk of glaucoma, a serious eye condition, a large comparative ...
Tech Xplore / RL-100 framework helps robots refine learned tasks amid real-world disruptions
Robots are gradually making their way into a variety of settings, ranging from households to public spaces, offices, factories and health care facilities. Despite their potential, however, many existing robots do not perform ...
Phys.org / Total eclipse gives scientists chance to probe sun's mysteries
Scientists plan to use a total solar eclipse that will be visible in Spain next week as a rare chance to learn more about the stormy, unpredictable nature of our star.
Phys.org / New quantum encryption method prevents ciphertext from being cloned
Digital security currently relies on difficult equations to protect data. For example, when you use a credit card online, the information is locked inside a math problem that would take a modern computer thousands of years ...
Medical Xpress / International project delivers hundreds of next-generation models for cancer research
Ten years and thousands of patient samples later, the National Cancer Institute (NCI) has published its results from the Human Cancer Model Initiative (HCMI) on the development of 665 organoid models of 25 types of cancer ...
Medical Xpress / Pretrained AI could help clinics analyze brain MRIs with few labeled scans
When it comes to medical imaging, a chatbot doesn't know its backside from its elbow. Or, at least, it can't tell a spine from a knee. But if a Boston University research team is successful, a smarter AI system for evaluating ...
Medical Xpress / Rare bone disease often goes untreated while patients quietly live with chronic pain
Teeth and bones are among the hardest structures in the human body, but certain inherited conditions can rob them of that strength. One of them is hypophosphatasia (HPP), a rare, lifelong genetic bone disorder that disrupts ...
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 / Fossils from Wyoming's Smiley Draw deepen understanding of early primate evolution
A new study from the University of Kansas complicates the picture of primates living in North America some 55 million years ago during the Eocene, a warm period that allowed mammals to diversify quickly.
Medical Xpress / IL-1 pathway may stop Candida fungus from turning fatal in weakened immunity
An immune pathway has been discovered that prevents a normally harmless fungus from developing into a fatal infection. The King's College London study, published in Nature Microbiology, provides the first potential clue as ...
