This is how some snakes can fly

Some snakes have evolved the ability to glide through the air. For example, paradise tree snakes in southeastern Asia can launch off from a branch and fly as far as 10 meters. Scientists have known that the snakes flatten their bodies to gain lift but new research reveals that they also undulate their bodies as they're gliding in order to remain stable. Johns Hopkins University mechanical engineer Isaac Yeaton and colleagues from Virginia Tech put reflective tape on snakes' bodies and then use...

Virginia Tech's fog harp harvests water even in the lightest fog

'We already knew that in heavy fog, we can get at least two times as much water,' said Boreyko. 'But realizing in our field tests that we can get up to 20 times more water on average in a moderate fog gives us hope we can dramatically enhance the breadth of regions where fog harvesting is a viable tool for getting decentralized, fresh water.'

Viruses don't have a metabolism; but some have the building blocks for one

'Giant viruses' are many times larger than typical viruses and have more complex genomes. Using publicly available metagenome data, researchers at Virginia Tech assembled genomes for more than 500 giant viruses and found a surprising number of genes for cellular metabolic cycles, including glycolysis, gluconeogenesis, and the TCA cycle. Viruses may deploy these genes to rewire their hosts' metabolism upon infection, expanding their ecological influence and blurring the distinction between viruse...

Virginia Tech scientists reveal brain tumors impact normally helpful cells

Unprovoked recurrent seizures are a serious problem affecting most patients who suffer from glioma, a primary brain tumor composed of malignant glial cells. Fralin Biomedical Research Institute researchers tested the hypothesis that glioma-induces processes that renders a type of brain cells dysfunctional, perpetuating the imbalance between excitation and inhibition in tumor-associated epilepsy.

Weather radar records drastic drop in mayfly populations

Researchers at the University of Oklahoma, the University of Notre Dame and Virginia Tech applied radar technology -- the same used for meteorology -- to quantify the number of mayflies that emerged annually from two different bodies of water: the Upper Mississippi River and the Western Lake Erie Basin. Their goal was to characterize the size of these swarms using the same technique a meteorologist would use to quantify the amount of precipitation that may fall from a cloud.

How Insects Cope With the Effects of Gravity

You wouldn't think gravity would be a big worry for insects. They're so small. So light. An ant that fell from a second-floor balcony and landed on its head wouldn't even get a bruise.Consequently, scientists have not concerned themselves greatly with what gravity does to insects. But a group of scientists who routinely put grasshoppers into the linear accelerator at the Argonne National Laboratory in Illinois decided to take a closer look.That's not as strange as it sounds. With...

ASU and Virginia Tech researchers unlock mysteries of grasshopper response to gravity

How do insects control the effects of gravity when they climb a tree or hang upside-down waiting for prey? They don't have closed circulatory systems that restrict fluid flow to certain parts of the body. ASU and Virginia Tech researchers discovered how insects adjust their cardiovascular and respiratory activity in response to gravity. When they change orientation, they respond to gravity just like humans, and they show many of the same physiological responses.

Is This the First Fossil of an Embryo?

A creature called Caveasphaera lived in China 609 million years ago, and it left behind fossils that resemble tiny grains of sand. But as innocuous as those fossils appear, they may speak volumes about our own evolutionary history.Under a microscope, the fossils turn out to be clusters of hundreds or thousands of cells. Were they on their way to developing into adult bodies? On Wednesday, a team of researchers published a study on hundreds of new Caveasphaera fossils, using high-powered X-ray be...

Oldest Frog Relative from North America Could Fit on Your Pinky Finger

It's possible that during the Triassic period, the crocodile-like phytosaur snapped at a frog-like creature, but missed. It's a good thing it did, because 216 million years later, paleontologists have found the fossils of these tiny creatures, the oldest known frog relative from North America, a new study finds.This frog -- nicknamed the Chinle frog because it was found in the Chinle Formation of northern Arizona -- is a big finding, but the creature itself was small, just over 0.5 inche...

Judge halts grizzly hunting because Yellowstone bears need to find more diverse sex partners

The grizzly bears are spared from hunting, for now.  For as low as $600 per hunting permit, grizzly bears were scheduled to be legally hunted in Wyoming beginning on Sept. 1, making it the first such hunt in over four decades. But after first just temporarily suspending the hunt, a federal judge has now bucked attempts by the U.S. Fish and Wildlife Service to remove the Yellowstone-area grizzlies from the endangered species list. The 48-page decision, however, wasn't about hunting. It was a...

Yellowstone won't erupt anytime soon, but a debate still rages about the supervolcano

Ying Zhou teaches a Geology 101 class to students at Virginia Tech, but after peering deeply into the subterranean world beneath the Yellowstone volcano, Zhou says she needs to modify her lesson plans — for Yellowstone, anyhow.  Yellowstone is one of the most heavily-researched volcanoes in the world, and it's believed to be responsible for few mega-eruptions in the last two million years. Volcanologists understand its behavior quite well, and there's agreement that any sort of eruptio...
