Phys.org / Global warming is speeding breakdown of major greenhouse gas, research shows
Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously ...
Medical Xpress / Shingles vaccination associated with delayed dementia onset in older adults
Every three seconds, someone, somewhere in the world, develops dementia. The number of people living with the condition is projected to rise dramatically, doubling from 78 million in 2020 to 139 million by 2050, making dementia ...
Tech Xplore / New design tool 3D-prints woven metamaterials that stretch and fail predictably
Metamaterials—materials whose properties are primarily dictated by their internal microstructure, and not their chemical makeup—have been redefining the engineering materials space for the last decade. To date, however, ...
Phys.org / Snakes on trains: King cobras are 'hopping railways' to unsuitable habitats in India
King cobras are the world's longest venomous snakes. So, imagine seeing one a few feet away as you embark on a train in India. The Western Ghats King Cobra (Ophiophagus kaalinga)—a vulnerable king cobra species found in ...
Phys.org / Acoustic study reveals deep-diving behavior of elusive beaked whales
Scientists have captured a rare view of one of the ocean's least understood whales—without ever seeing it. By listening to the sounds beaked whales naturally produce, researchers have reconstructed a three-dimensional picture ...
Medical Xpress / Eye movements help the brain see in 3D: Research challenges long-standing assumption
When you go for a walk, how does your brain know the difference between a parked car and a moving car? This seemingly simple distinction is challenging because eye movements, such as the ones we make when watching a car pass ...
Phys.org / CFC replacements behind vast quantities of global 'forever chemical' pollution, research reveals
Chemicals brought in to help protect our ozone layer have had the unintended consequences of spreading vast quantities of a potentially toxic "forever chemical" around the globe, a new study shows. Atmospheric scientists, ...
Phys.org / Huge areas of Australia are vulnerable to tree-killing beetle, study warns
A new Curtin University study warns that large parts of Australia, including major cities and farming regions, could be highly vulnerable to a fast-spreading invasive beetle, already causing severe damage across the Perth ...
Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Phys.org / Quick test can curb antimicrobial resistance, identifying bacteria and antibiotic susceptibility in under 40 minutes
McGill researchers have developed a diagnostic system capable of identifying bacteria—and determining which antibiotics can stop them—in just 36 minutes, a major advance in the global effort to curb antimicrobial resistance ...
Phys.org / Honest or deceptive? What a new signaling model means for animal displays and human claims
For decades, scientists have tried to answer a simple question: why be honest when deception is possible? Whether it is a peacock's tail, a stag's roar, or a human's résumé, signals are means to influence others by transmitting ...
Phys.org / Bacteria can survive washing and disinfection in food production plants
Bacteria in food can make you seriously ill, which is why it is so important for the facilities that produce your food to ensure proper hygiene in their production lines. A new doctoral thesis from NTNU has investigated how ...
