Court tosses Virginia challenge to healthcare law
WASHINGTON (Reuters) - An appeals court handed President Barack Obama another victory for his signature healthcare law on Thursday, rejecting challenges by the state of Virginia and others seeking to invalidate the law as unconstitutional. The U.S. Court of Appeals for the Fourth Circuit overturned a lower court judge who had ruled the federal government could not compel people to buy health insurance or face paying a penalty, known as the individual mandate and a critical part of Obama's avowed effort to cut healthcare costs.
Scientists find gene that controls chronic pain
LONDON (Reuters) - British scientists have identified a gene responsible for regulating chronic pain, called HCN2, and say their discovery should help drug researchers in their search for more effective, targeted pain-killing medicines. Scientists from Cambridge University said that if drugs could be designed to block the protein produced by the gene, they could treat a type of pain known as neuropathic pain, which is linked to nerve damage and often very difficult to control with currently available drugs.
Kids who live with smokers have more ear infections

Mutant genes found for asthma, point to possible therapy
HONG KONG (Reuters) - A drug used to treat rheumatoid arthritis could help asthma patients, scientists said on Friday, as they identified two mutant genes that may predispose a person to asthma. Over 235 million people worldwide suffer from asthma and it is the most common chronic disease among children, according to the World Health Organization.
Fewer screening colonoscopies OK for some: study
NEW YORK (Reuters Health) - People who've had a colonoscopy with no signs of cancer may be able to delay the next one or not have it at all, German researchers suggest. Guidelines from the U.S. Preventive Services Task Force, a federally supported expert panel, currently recommend that people at average risk of colon cancer start screening for the disease at age 50, using one of a number of tests that have all been found to cut the risk of dying from colon cancer.
