Telomeres And Cancer: Elusive Telomere RNA Subunit Identified In Singl
Scientists have identified the long-sought telomerase RNA gene in a single-cell research model. Chromosomes shorten with every cell division. In stem cells and in cancer cells, this shortening is compensated by telomerase, an enzyme that adds short repeat sequences to the ends of chromosomes to replenish lost DNA. As telomerase is required for the continued growth of most cancer cells, the enzyme is considered a promising target for new anti-cancer drugs. A correlation between telomere length and a variety of diseases has further intensified interest in understanding telomerase and its regulation. Heavy, Lifetime Alcohol Users May Be Toasting Metabolic Syndrome
The risk of developing metabolic syndrome increases the more a person drinks -- and beginning a heavy drinking pattern early in life seems to add extra risk, according to a first-of-its-kind study presented at the American Heart Association's Scientific Sessions 2004. Steve Jobs Unveils New iMacs, Revamps iLife 08, Adds iPhone Features

Plans for pop-up ads and restrictions on copying have some consumer advocates wondering about Tivo's commitment to customer control. The company says it has to bow some to Hollywood and advertiser interests. Abstinent Alcoholics Can Have Reduced Brain Activation Without Apparen
Heavy alcohol use can lead to structural and functional changes in the brain. New findings show that even when structural damage may not be apparent, brain activation can still be reduced. Researchers refer to this alcohol-induced damage as "latent lesions."A new examination of memory retrieval among recovering alcoholics has found lower activation than among nonalcoholics in key areas of the brain even in the absence of demonstrable brain structural damage. Glitch Leads to Segway Recall
In rare circumstances, the gyroscope-controlled scooters can reverse course and toss their riders. Resulting safety concerns cause the manufacturer to pull back all shipped units for a software upgrade. [Obvious] Chicago Tribune Pulls 'Vulgar' Section
A preprinted section was pulled from Wednesday's Chicago Tribune because it contained an article discussing the use of a vulgar slang term in referring to women, according to the newspaper. Researcher: Global Warming Not To Blame For Tsunami
The shock and awe resulting from the massive tsunami that hit Indian Ocean nations Dec. 26 has left many wondering what could have caused such a disaster and if there is anything humans can do to control or mitigate future events. Some quickly suggested that an increase in the frequency of natural disasters like the tsunami were a harbinger of what we have in store due to the increase of Earth's greenhouse gases resulting from the burning of fossil fuels. Diabetes: A Link Between Oral And Overall Health?
Diabetes affects 18.2 million people in the United States and is expected to double by the year 2010. Additionally, diabetics who do not have good control over their blood sugar levels are more susceptible to oral health problems than non-diabetics, according to a study that appears in the November/December 2004 issue of General Dentistry, the Academy of General Dentistry's (AGD) clinical, peer-reviewed journal. Unique Dual Treatment For Liver Cancer Packs Curative Punch
It's been five years since Dave Smethurst had 10 tumors removed from his liver. After surgery, three remained, too difficult for surgeons to safely remove. The average patient lives less than six months with liver tumors that cannot be removed surgically. But after receiving a new type of treatment pioneered at the University of Michigan Comprehensive Cancer Center, Smethurst has reached the magical five-year mark.
