Counting Atoms with Glass Fiber
Glass fiber cables are indispensable for the internet - now they can also be used as a quantum physics lab. The Vienna University of Technology is the only research facility in the world, where single atoms can be controllably coupled to the light in ultra-thin fiber glass. Specially prepared light waves interact with very small numbers of atoms, which makes it possible to build detectors that are extremely sensitive to tiny trace amounts of a substance.

Scientists Point to Link between Missing Synapse Protein and Abnormal Behaviors
Although many mental illnesses are uniquely human, animals sometimes exhibit abnormal behaviors similar to those seen in humans with psychological disorders. Such behaviors are called endophenotypes. Now, researchers at the California Institute of Technology (Caltech) have found that mice lacking a gene that encodes a particular protein found in the synapses of the brain display a number of endophenotypes associated with schizophrenia and autism spectrum disorders.

Hydrogen peroxide provides clues to immunity, wound healing, tumor biology
Hydrogen peroxide isn't just that bottled colorless liquid in the back of the medicine cabinet that's used occasionally for cleaning scraped knees and cut fingers. It's also a natural chemical in the body that rallies at wound sites, jump-starting immune cells into a series of events. A burst of hydrogen peroxide causes neutrophils, the immune system's first responders, to rush to the wound to fight microorganisms, remove damaged tissue and then start the inflammation process.

Blocked holes can enhance rather than stop light going through, engineers find
Blocked holes can enhance rather than stop light going through, engineers find
by Steven Schultz Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all, but rather enhances its transmission.

Promising anti-HIV agents
Researchers at Yale University have discovered new chemical compounds that prevent HIV from replicating in human T-cells. These compounds could result in new, highly effective HIV treatments that are 10 to 2000 times more potent than HIV drugs now on the market. "The current compounds or slight variants could become drugs," said Professor William L. Jorgensen, one of two principal investigators behind the research.

Schizophrenia linked to memory process
Genetic mutations that cause schizophrenia could be linked to systems in the brain responsible for learning and memory. University researchers from Edinburgh have identified changes to genes - genetic mutations - in patients with schizophrenia who had not inherited the condition. The study, which was carried out with Cardiff University, showed that these mutations occurred among a set of proteins that play a key role in memory function.

Scientists design experimental treatment for iron-overload diseases
Iron overload is a common condition affecting millions of people worldwide. Excess iron in the body is toxic, and deposits can cause damage to the liver, heart and other organs. Current treatments, researchers say, are not ideal and have significant side effects. Iron in the body is regulated by a hormone called hepcidin, and a deficiency in this hormone can cause the iron overload seen in genetic disorders like hereditary hemochromatosis and Cooley's anemia.
