Cigarette smoking is a well-known risk factor for a wide-range of diseases. Now, scientists have evidence that smoking may also increase the risk of age-related cataract, the leading cause of blindness and vision loss in the world.

Startup Targets Genes Tied to Heart Disease

A company working on drugs for genetic heart disease is among several tying therapies to genes. In September, a biotech company started up in San Francisco with a goal of using a novel genomics-based approach to developing drugs for cardiomyopathy, a life-threatening heart condition that affects 60 million people worldwide. The company, called MyoKardia, is going after people who have genetic...

The body's own recycling system

Times of distress literally eat away at the core of starving cells: They start to digest their own parts and recycle them for metabolic purposes. Ingo Schmitz at the Helmholtz Centre for Infection Research in Braunschweig, Germany, together with a team of researchers, has discovered that a "molecular brake" is in charge of regulating autophagy to keep it from getting out of control. They published...

Veterans are at higher risk of alcohol abuse relapse due to smoking

In a new study published in Frontiers, Dr. Timothy Durazzo and colleagues from the San Francisco VA Medical Center and University of California, San Francisco, expand upon their decade of research showing that smoking while kicking the alcohol habit impairs memory, learning and other cognitive skills--ultimately making it more difficult to weather the long storm of sobriety.

3G protocols come up short in privacy, say researchers

(Phys.org)—Researchers from the UK and Germany have found that 3G telephony systems pose a security weakness that results in threats to user privacy. The weakness makes it possible for stalkers to trace and identify subscribers. Their paper, "New Privacy Issues in Mobile Telephony: Fix and Verification," says that 3G systems come up short in preventing unauthorized parties from tracking the...

First evidence of dynamo generation on an asteroid found

About 4.6 billion years ago, the solar system was little more than a tenuous disk of gas and dust. In the span of merely 10 million years, this soup evolved to form today's massive, complex planets. In the intervening period, however, the solar system contained a mixture of intermediary bodies—small chunks of rock, the remnants of which today are known as asteroids.
