Despite health warnings, Americans still sit too much: Survey of 50,000 people across multiple ages, racial, ethnic groups documents troubling trends

The research team analyzed surveys of 51,000 people from 2001 to 2016 to track sitting trends in front of TVs and computers and the total amount of time spent sitting on a daily basis.

Deadly box jellyfish antidote discovered using CRISPR genome editing: Pain researchers uncover secrets to box jellyfish venom

The Australian box jellyfish (Chironex fleckeri) has about 60 tentacles that can grow up to three metres long.Each tentacle has millions of microscopic hooks filled with venom.

Arctic warming will accelerate climate change and impact global economy

A new paper in Nature Communications reveals a combination of these factors has the potential to increase the long-term economic impact of climate change by just under $70 trillion, under mitigation levels consistent with current national pledges to cut carbon emissions (5% of the estimated total cost of climate change

Running may have made dinosaurs' wings flap before they evolved to fly: New evidence suggests that passive wing flapping may have arisen earlier than gliding flight

The findings, published in PLOS Computational Biology, provide new insights into the origin of avian flight, which has been a point of debate since the 1861 discovery of Archaeopteryx.

Experimental device generates electricity from the coldness of the universe

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe..

Knit 1, purl 2: Assembly instructions for a robot? Researchers make soft, actuated objects using commercial knitting machines

Software developed by researchers from CMU's Morphing Matter Lab and Dev Lab in the Human-Computer Interaction Institute makes it possible for the objects to emerge from the knitting machines in their desired shapes and with tendons already embedded. They can then be stuffed and the tendons attached to motors, as

Water found in samples from asteroid Itokawa: Up to half of Earth's ocean water may have come from impacts by asteroids

The team's findings suggest that impacts early in Earth's history by similar asteroids could have delivered as much as half of our planet's ocean water.

Researchers crack the peanut genome: New genome map sheds light on ancestry, diversity of today's peanuts

Researchers working as part of the International Peanut Genome Initiative have previously pinpointed one of the peanut's two wild ancestors and shown that the peanut is a living legacy of some of the earliest human agricultural societies in South America. Since then the team has mapped the entire peanut genome

Arsenic-breathing life discovered in the tropical Pacific Ocean

"Thinking of arsenic as not just a bad guy, but also as beneficial, has reshaped the way that I view the element," said first author Jaclyn Saunders, who did the research for her doctoral thesis at the UW and is now a postdoctoral fellow at the Woods Hole Oceanographic Institution

5 Remarkable Examples of Animal Intelligence That Will Leave You in Awe

Animal intelligence could stretch to more than just an elephant’s excellent memory! As these examples will reveal..

Scientists print first 3D heart using patient's biological materials: Engineered heart completely matches the immunological, cellular, biochemical and anatomical properties of the patient

Until now, scientists in regenerative medicine -- a field positioned at the crossroads of biology and technology -- have been successful in printing only simple tissues without blood vessels.

Features that make lizards appealing to potential mates are resilient to stress

"Animals in the wild experience stress every day when they flee from predators, fight with others over food, or face extreme weather," said Kirsty MacLeod, a postdoctoral scholar at Penn State at the time of the research and lead author of the paper. "But they are facing increasing amounts of
