Phys.org / Where are Europe's oldest people living? What geography tells us about a fragmenting continent
For over a century and a half, life expectancy has steadily increased in the wealthiest countries. Spectacular climbs in longevity have been noted in the 20th century, correlating with the slump in infectious illnesses and ...
Phys.org / Oysters play unexpected role in protecting blue crabs from disease
Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research from William & Mary's Batten School of Coastal & Marine Sciences & VIMS shows they can ...
Phys.org / Scientists use RNA nanotechnology to program living cells, opening a new path for cancer cure
Scientists at Rutgers University–Newark have developed a first-of-its-kind RNA-based nanotechnology that assembles itself inside living human cells and can be programmed to stop propagation of harmful cells. The findings, ...
Phys.org / Nanocrystal biohybrids harvest light to reduce N₂ gas to ammonia
Ammonia, a key part of nitrogen fertilizers, is central to sustaining global food production. However, its manufacture is also energy intensive: Ammonia production requires 2% of global energy to meet global demand. Approximately ...
Phys.org / Lab-grown beef: Novel line of bovine embryonic stem cells shows promise
Researchers in the College of Agriculture, Health and Natural Resources have developed a novel line of bovine embryonic stem cells, which have significant potential for a variety of new innovations, from lab-grown meat to ...
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 / From cryogenic to red-hot: Optical temperature sensing from 77 K to 873 K
An international collaboration involving researchers from the University of Innsbruck has developed a novel luminescent material that enables particularly robust and precise optical temperature sensing across an exceptionally ...
Phys.org / Orange, camphor-smelling solid could be a key to the next generation grid-storage batteries
An orange solid with a camphor-like odor has helped aqueous zinc-iodide batteries move a large step closer to supplying safe and economic grid and household energy storage.
Phys.org / From sea to space: Turning the tide on microplastic pollution with satellite technology
What do microplastics, water color, and satellites have in common? Dr. Karl Kaiser, professor of marine and coastal environmental science in the College of Marine Sciences and Maritime Studies at Texas A&M University at Galveston ...
Phys.org / From single queens to mega-colonies: How ant societies are shaped by the environment
A single queen in the tropics; large colonies in deserts; workers with uniform morphology in temperate regions; ant social structures vary according to environmental conditions. This is shown, for the first time at a global ...
Phys.org / Well-behaved dogs generally have lower cortisol and higher serotonin, study finds
Dogs who scored well on the Wesen test, which is used to analyze a dog's temperament, tended to have lower levels of cortisol, often called the "stress hormone," and higher levels of serotonin, often called the "happiness ...
Phys.org / Hadean zircons reveal crust recycling and continent formation more than 4 billion years ago
Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought. New research led by scientists at the University of Wisconsin–Madison has uncovered chemical signatures ...
