Quantum Ghosts Are Helpful

Physicists have harnessed the phenomenon, "spooky action at a distance," to shed light on another unusual and previously difficult aspect of quantum physics -- that of distinguishing between two similar quantum devices.

World's Fastest Camera Relies On Entirely New Type Of Imaging

Scientists have developed an entirely new approach to imaging that does not require a CCD or CMOS camera. Building on more than a decade of research on photonic time stretch, a technique for capturing illusive events, the team has demonstrated a continuous running camera that captures images at 6 million frames per second, roughly a thousand times faster than conventional...

Magnesium Detected In MESSENGER Flyby Of Mercury

NASA's MESSENGER spacecraft served up another curveball after a second flyby of the hot inner planet Oct. 6 detected magnesium -- an element created inside exploding stars and which is found in many medicine cabinets on Earth -- clumped in the tenuous atmosphere of the...

Flu Vaccine Given In Microneedle Skin Patches Proves Effective In Mice

Flu vaccine delivered through skin patches containing microneedles has proven just as effective at preventing influenza in mice as intramuscular, hypodermic flu immunization. A team of researchers believes the new microneedle skin patch method of delivering flu vaccine could improve overall seasonal vaccination coverage in people because of decreased pain, increased convenience, lower cost and...

How Mercury Emissions Reach Tuna And Other Seafood, And Why Mercury Contamination Is Likely To Worsen

A new study documents for the first time the process in which increased mercury emissions from human sources across the globe, and in particular from Asia, make their way into the North Pacific Ocean and as a result contaminate tuna and other seafood. Because much of the mercury that enters the North Pacific comes from the atmosphere, scientists have predicted an additional 50 percent increase in...

Novel Role Of Protein In Generating Amyloid-beta Peptide

A defining hallmark of Alzheimer's disease is the accumulation of the amyloid-beta protein, otherwise known as "senile plaques," in the brain's cortex and hippocampus, where memory consolidation occurs. Researchers have identified a novel protein which, when over-expressed, leads to a dramatic increase in the generation of the amyloid-beta...

Arcobacter: Foodborne Pathogen's Genome Exposed

If a little-known microbe called Arcobacter butzleri has contaminated the water you drink or the food you eat, this troublesome pathogen could make you sick. Symptoms include diarrhea, stomach cramps, nausea, vomiting and fever, all of which can become chronic if left...

Cave Activity Discouraged To Help Protect Bats From Deadly White-nose Syndrome

White-nose syndrome, a wildlife crisis of unprecedented proportions, has killed hundreds of thousands of bats from Vermont to West Virginia and continues unchecked. Now, the U.S. Fish and Wildlife Service is asking those who use caves where bats hibernate - called hibernacula - to take extra precautions and to curtail activities to help prevent the spread of...

Palm Oil Not A Healthy Substitute For Trans Fats

Manufacturers are now required to state on food labels the amount of trans fatty acids, also called hydrogenated fats, in packaged foods. Both trans fatty acids and saturated fatty acids are associated with elevated heart disease risk factors.
