How hummingbirds evolved to fly at high altitude
(Phys.org) —High up in the Andes, numerous species of hummingbirds are thriving despite low levels of oxygen.
Plasma tool for destroying cancer cells
Plasma medicine is a new and rapidly developing area of medical technology. Specifically, understanding the interaction of so-called atmospheric pressure plasma jets with biological tissues could help to ...
Scientists discover first multicellular life that doesn't need oxygen
Algae and bacteria hogged oxygen after ancient mass extinction, researchers say
(PhysOrg.com) -- After the biggest mass extinction in Earth's history -- 250 million years ago -- ocean algae and bacteria rebounded so fast that they consumed virtually all the oxygen in the sea, slowing ...
Niacin, the fountain of youth
The vitamin niacin has a life-prolonging effect, as Michael Ristow has demonstrated in roundworms. From his study, the ETH-Zurich professor also concludes that so-called reactive oxygen species are healthy, ...
Scientists notch a win in war against antibiotic-resistant bacteria
A team of scientists just won a battle in the war against antibiotic-resistant "superbugs"—and only time will tell if their feat is akin to the bacterial "Battle of Gettysburg" that turns the tide toward ...
The secrets of a tadpole's tail and the implications for human healing
Scientists at The University of Manchester have made a surprising finding after studying how tadpoles re-grow their tails which could have big implications for research into human healing and regeneration.
Nanoparticles detect biochemistry of inflammation
Inflammation is the hallmark of many human diseases, from infection to neurodegeneration. The chemical balance within a tissue is disturbed, resulting in the accumulation of reactive oxygen species (ROS) such as hydrogen ...
Professor's hypothesis may be game changer for evolutionary theory
(PhysOrg.com) -- A new hypothesis posed by a University of Tennessee, Knoxville, associate professor and colleagues could be a game changer in the evolution arena. The hypothesis suggests some species are ...
Research may unlock enzyme's role in disease
A UT Arlington chemist doing National Science Foundation-funded research on enzymes that regulate human biology has uncovered characteristics that could be used to identify predisposition to conditions such ...
Ceria nanoparticles could lessen the damage from ischemic strokes
(Phys.org)—The most common form of strokes are caused by a sudden reduction in blood flow to the brain (ischemia) that leads to an inadequate supply of oxygen and nutrients. These so-called ischemic strokes ...
Nanoparticles reboot blood flow in brain
A nanoparticle developed at Rice University and tested in collaboration with Baylor College of Medicine (BCM) may bring great benefits to the emergency treatment of brain-injury victims, even those with mild injuries.
Sticking power of plant polyphenols used in new coatings
A simple kitchen sink experiment helped Northwestern University researchers discover that green tea leaves not only can be used to steep a good cup of tea, but they make an excellent antibacterial coating, too.
