Phys.org / Who's watching who? Otters turn their attention to humans
For many people, a trip to the zoo is a chance to watch playful otters dart through the water and chatter with one another. But while we may worry that crowds could stress the otter community, a new Australian study shows ...
Phys.org / Deep-learning approach rapidly predicts where metals bind within proteins
In the living world, roughly a third of all proteins we know rely on metals to function. Zinc helps enzymes break down molecules, iron helps carry oxygen in the blood, calcium helps relay signals in cells and potassium flows ...
Phys.org / How only a few tree species drive Amazon forest recovery
When a destroyed section of the Amazon rainforest begins to recover, nature deploys only a few tree species that can withstand poor soil conditions and blazing sun and grow rapidly, a Brazilian study has shown.
Phys.org / Most species in UK zoos are non-native and not threatened, undermining conservation goals
In British zoos and aquariums, fewer than 10% of vertebrate species are native to the UK, and just 2% are high conservation priorities, according to a study by Justin Lennon at the University of Brighton and colleagues, published ...
Phys.org / Labrador Sea a key player in providing oxygen for deep North Atlantic life
Researchers from Cornell University have pinpointed the source of oxygen that sustains deep-sea life in the North Atlantic Ocean: the churning waters in the Labrador Sea.
Phys.org / Each degree of warming could add a month of intolerable heat for 1 billion people
The threat that rising temperatures fueled by climate change pose to the health of older people has been dramatically underestimated, according to a U.S. modeling study published Tuesday.
Phys.org / An African bat overlooked for two centuries is confirmed in Europe
An African bat whose presence in Sicily had remained an unresolved zoological mystery for almost two centuries has now been documented on Pantelleria Island. A study published in Global Ecology and Conservation reports the ...
Phys.org / Locust neurons detect PFAS at environmentally relevant levels, pointing to portable sensors
Researchers at Michigan State University have discovered that neurons in a locust's brain can distinguish among multiple PFAS compounds, including PFOS, one of the world's most common "forever chemicals," at environmentally ...
Phys.org / Giant crocodylians dominated the food chain in Miocene South America, fossil evidence suggests
South America was a frightening place during the Miocene. More than 10 million years ago, a vast lake covered much of the continent, home to giant turtles and crocodylians.
Medical Xpress / County vaccination data may mask school-level measles risk
Pockets of low vaccination rates in some schools help explain why measles outbreaks have been climbing in the U.S., even when county-level vaccination numbers—the data policymakers consult—appear high enough to provide community ...
Phys.org / A weakening Atlantic Ocean current system could accelerate Earth's warming
A current system in the Atlantic Ocean that shapes regional climates and distributes ocean nutrients also serves as a control knob to help regulate temperatures across the planet, new research has found.
Medical Xpress / Most patients view their test results before their doctor, with some reporting low comprehension
You get a message that a test result is available in your online patient portal. Do you look at it right away, or do you wait to hear from your health care provider?
