It's an occurrence that happens so fast it cannot be followed by the human eye.  However, researchers at MIT, Virginia Tech and Princeton University announced on Thursday that they have solved the mystery of how cats lap liquids with such elegance.Using high-speed cameras, the researchers found that domestic cats and larger felines like tigers use their tongues to delicately draw up water without breaking the surface of the liquid, harnessing a perfect balance between the physical forces...

A new experiment proposed by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances"”a scale at which exotic new details of gravity's behavior may be detectable.Of the four fundamental forces that govern interactions in the universe, gravity may be the most familiar, but ironically it is the least understood by physicists. While gravity's influence is well-documented on...

Most animals don't think anything of breaking into a run: they switch effortlessly from walking to a high-speed bouncing run. But what about elephants? Their sheer size makes it impossible for them to bounce up in the air at high speeds. So how are high-speed elephants moving: are they running or walking? At a first glance, fast-moving elephants look as if they are walking, according to John Hutchinson from the Royal Veterinary College, UK. But closer analysis of elephant footfall patterns by...

STATE COLLEGE, Pa., July 22 /PRNewswire/ -- In order to encourage community-wide energy efficiency, GreenQuest has launched the "School's Out Promotion" for school districts.

Through the School's Out campaign, school districts can provide GreenQuest to their students, staff and community members at no...

Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers.These precarious bits, formed in this case by arrays of semiconductor quantum dots containing a single extra electron, are easily perturbed by magnetic field fluctuations from the nuclei of the atoms creating the quantum dot. This perturbation causes the bits to essentially forget the piece of information they were tasked with storing.A quantum dot is a semiconductor...

GARDINER, N.Y., June 23 /PRNewswire/ -- "The Universal Properties of Acceleration: Did Einstein Look the Wrong Way?" (published by AuthorHouse) is about gravity. Author Barry Lebost proposes a new law in physics stating "that all acceleration and its intimate partner inertia have the same general properties everywhere in the universe including the surfaces of planets and stars." Lebost demonstrates that when universal property tests are performed upon the surface of planet Earth, the test...
