For data transmission over the Internet, electrical computer signals are converted into light signals and conducted via fiber optic cables to the recipient.Once there, they are converted back into electrical signals. These light signals can be tapped into on the cables, enabling unauthorized persons to intercept data without detection. However, this does not go undetected if single light particles, photons, are used for encryption based on quantum cryptography….
The new method opens up new realms of study, ones that might have long-ranging implications for biofuels research and crop genetics.“The data we’re seeing are…
From an engineer’s perspective, plants such as palm trees, bamboo, maples and even potatoes are examples of precise engineering on a microscopic scale. Like…
When averaged, the predictions have come in remarkably close to the mark in the past two years. But the low and high predictions are off by hundreds of…
Enzymes can be efficient biocatalysts for organic synthesis, but often only work on a small range of specific substrates. Yoshihito Watanabe and colleagues at…

The Tropical Rainfall Measuring Mission satellite known as TRMM is managed by both NASA and the Japanese Space Agency. From its orbit in space, TRMM's…
They are often only visible to those in flight above a storm, and happen so quickly you might not even see it unless you chance to be looking directly at it….
Many elderly people spend their last years alone. Spouses pass and children scatter. But being lonely is much more than a silent house and a lack of…
Two researchers at Weill Cornell Medical College have deciphered a mouse's retina's neural code and coupled this information to a novel prosthetic device to…
Tiny space age probes — those that can see inside single living cells — are increasingly being used to diagnose illness in hard-to-reach areas of the body. NewYork-Presbyterian Hospital/Weill Cornell Medical Center's Dr. Michel Kahaleh often threads a tiny microscope into the narrow bile ducts that connect the liver to the small intestine to hunt for cancer. He also uses the device to minutely explore the pancreatic duct as one of a few doctors in the country to use such technology in this way….
At the 4th EuCheMS (August 26-30) in Prague, FIZ CHEMIE will be showing how professional information services can today efficiently support teaching, research…
Experiments using heavy ions at CERN1’s Large Hadron Collider (LHC) are advancing understanding of the primordial Universe. The ALICE, ATLAS and CMS…
Although the probability that hurricanes will hit such conditions is small, ranging from 10 to 23 percent, the effect is potentially large: Hurricanes can…
Yo-yo dieting – the repetitive loss and regain of body weight, also called weight cycling – is prevalent in the Western world, affecting an estimated 10…
