Living among large predatory carnivores could actually make you safer. A study published in the journal Current Biology found that pumas—wild cats also known as mountain lions, cougars or panthers—change deer behavior, leading ...
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 ...
Medical Xpress / Immune cell dysfunction, not absence, defines skin cancer in immunosuppressed patients
Researchers at The University of Texas MD Anderson Cancer Center have discovered that immunosuppressed patients with non-melanoma skin cancer are not missing the key cancer-fighting immune cells found in immunocompetent patients, ...
Phys.org / Melting sea ice combines with Arctic sea to make clouds
Scientists have uncovered a previously unknown natural process that dramatically increases the number of cloud-forming particles in the Arctic atmosphere—potentially altering cloud cover, sunlight reflection and future climate ...
Phys.org / Catalyst converts CO₂ into high-value industrial chemical at room temperature with record efficiency
A research team has developed a highly efficient catalyst that directly converts carbon dioxide—a major contributor to global warming—into high-value industrial 2-propanol. The research was published online in Applied Catalysis ...
Medical Xpress / Containment costs reveal when pandemic measures should shift from none to intensive
In the event of a pandemic, every society is confronted with the question: How can the spread of an infectious disease be effectively contained without restricting daily life more than necessary? Measures such as mandatory ...
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 ...
Phys.org / A new species of Ice Age toad discovered at La Brea Tar Pits: The spadefoot toad Spea labreae
For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian ...
Medical Xpress / Avoiding three things during middle age is linked to 13 more years without dementia
Having normal blood pressure, no diabetes and not smoking between ages 45 and 65 is associated with nearly 13 additional years of dementia-free life, on average, a new study shows. Led by NYU Langone Health researchers, the ...
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 / A new reason to use the whole watermelon: USDA adds official nutrition profile for watermelon rind
Watermelon's rind is finally getting some respect. The fruit's outer layer now has an official nutrition profile in USDA FoodData Central, giving registered dietitians, researchers, recipe developers and other food professionals ...
Medical Xpress / Dementia after age 90: Study clarifies who may be at higher risk
It may seem natural to assume that people experience cognitive decline after age 90, but until recently, researchers had limited evidence about how advanced age affects the brain. This major knowledge gap will need to be ...
