Phys.org / India faces rising uncompensable heat stress, especially during monsoon season
Animals struggle to cool down in extreme heat and high humidity, and heat stress is rising in many regions around the world. This is especially true for people in tropical countries, including populous India. In a new paper ...
Phys.org / Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances ...
Medical Xpress / Brain cancer cells exploit normal nerve signaling to multiply and invade, new study finds
Gliomas are malignant brain tumors that originate from glial cells, which do not produce electrical impulses like neurons but instead support neurons by maintaining their structure and function. They are the most common form ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Phys.org / Two oceans, one country—and 20 times more sharks in the prehistoric Pacific
How many sharks should a coral reef have? It sounds like a simple question, but almost nowhere on Earth is there a reef that has not at some time been fished or otherwise affected by humans, so there is no yardstick against ...
Medical Xpress / A new target in the gut for reducing Alzheimer's risk
A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could ...
Phys.org / Active supermassive black holes may help form massive planets
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...
Phys.org / Layered nano-biohybrid uses sunlight, air and water to make hydrogen peroxide
A research team led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has developed a new material that combines inorganic material with biological components to produce hydrogen peroxide more efficiently.
Medical Xpress / Why brain imaging struggles to identify psychiatric disorder signatures
For decades, neuroscientists have been trying to determine whether different neuropsychiatric conditions are linked to specific variations in brain structure and neural connections. While past studies identified possible ...
Phys.org / Fulfilling friendships linked to better health and well-being across 22 countries
Fulfilling friendships and close social relationships are strongly linked to excellent physical and mental health, finds a substantial global study published in the Journal of Mental Health.
Phys.org / Complex suicidal somersault behavior in male redback spiders may be explained by surprisingly simple genetics
The Australian redback spider (Latrodectus hasselti), a cousin of the North American black widow spider, is known to practice sexual cannibalism, which is somewhat common among spider species. However, the male Australian ...
Phys.org / Synchronized star pairs unleash radio bursts via a Jupiter-Io-like mechanism
Researchers have helped unravel the mystery of why certain pairs of stars pulse with regular, long-period bursts of radio waves. The particular class of objects observed comes in pairs that always include a compact dead star, ...
