      Red Alert: Energy Drink Thickens Blood

      (Newser) - Drinking Red Bull could lead to heart problems, the London Times reports. In a small study—30 Australian college students took part—downing even one can of the hypercaffeinated energy drink increased the risk of blot clots. In short, the young Red Bull enthusiasts developed a condition that resembled cardiovascular disease. More »

      Brewhaha Over Coffee Muddies Health Facts

      (Newser) - Coffee’s health risks and benefits have been widely debated, often with contradictory “facts” emerging simultaneously—but can they all be right? Yes, Jane Brody writes in the New York Times . For instance, below 550 milligrams of caffeine, beverages are not diuretic (though they are beyond that); and while caffeine causes blood pressure to spike temporarily, long-term hypertension among coffee-drinkers is no more likely.

      Guzzle Coffee, Prevent Multiple Sclerosis?

      (Newser) - For preventing the autoimmune disease multiple sclerosis, caffeine might be just what the doctor ordered, the Daily Telegraph reports. In a study involving what must have been some very jittery mice, researchers found that the equivalent of 6-8 cups of coffee per day conferred protection from the rodent equivalent of MS. Don't rush off to Starbucks yet, though. More »

      Coffee's Smell Alone Can Perk You Up

      (Newser) - The aroma of coffee is enough to wake you up, a new study shows. Smelling coffee stimulated the expression of genes known to reverse the damaging effect of stress and sleep deprivation in test animals’ brains, international researchers tell LiveScience. Coffee’s stimulating effects have been known for ages, but are usually attributed to its caffeine kick. More »

    • A Coffee a Day May Keep Dementia Away: Study

      BBC  |  Apr 3, 08 4:52 AM CDT

      A Coffee a Day May Keep Dementia Away: Study

      (Newser) - A daily fix of caffeine helps shield the brain from the damaging effects of cholesterol, which is apparently the way coffee helps reduce the risk of dementia, new research suggests. The "blood-brain barrier" protects the brain from toxins in the bloodstream, but scientists have discovered that cholesterol makes it leaky. The strength of the barrier was boosted in rabbits given the caffeine equivalent of a daily cup of joe, reports the BBC. More »

    • Why Fork Over $11,000 for a Coffee Machine?

      Slate  |  Mar 13, 08 7:18 PM CDT

      Why Fork Over $11,000 for a Coffee Machine?

      (Newser) - A cup of coffee brewed with 16 ounces of water at 203 degrees for 44 seconds? Coming right up. The brouhaha over the $11,000 Clover 1s—the ultra-high-tech machine that brews one cup at a time—makes sense, Paul Adams writes in Slate. After two hours test-driving the built-to-order machine, which regulates temperature, water, and brew time with staggering precision, he considers himself “a Clover addict.” More »

      (Newser) - For those wide-eyed deep into the night, rising and shining with the early birds might seem like an elusive dream that comes to a jarring end each morning. But for this 5% to 30% of the population, understanding circadian rhythms can benefit their tired eyes more than chugging coffee. The Wall Street Journal's health columnist looks at ways to catch some Zs. More »

      (Newser) - Help may be on the way for tired Americans in the form of a nasal spray that eliminates sleepiness without apparent side effects, reports Wired . UCLA scientists testing the naturally occurring brain hormone orexin A found that when used as a spray, it allowed sleep-deprived monkeys to perform as well as rested monkeys. More »

      Peppy Combo May Battle Skin Cancer

      (Newser) - A 1-2 punch of caffeine and exercise may help prevent skin cancer. Hairless mice fed caffeinated water who worked out on a running wheel showed an increase in destruction of skin cells damaged by UVB rays, the AP reports, and the secret appears to be the combination. Researchers caution, however, that sunscreen remains the best skin cancer prevention. More »

      'Caffeinated' Workout May Cut Cancer

      (Newser) - New research suggests that drinking coffee, combined with regular exercise, speeds up the killing off of cells damaged by ultraviolet-B radiation. Researchers at Rutgers University specifically examined UVB apoptosis — the programmed death of cells that become damaged by ultraviolet rays – in hairless mice. This sort of cell-suicide helps prevent the formation of deadly melanoma skin cancer. The mice were divided into four groups for the study. The first group drank the equivalent of one or two cups of coffee per day. The second group exercised regularly on a running wheel. The third had both caffeine and exercise, and a fourth group had neither. The rate of cell suicide was 400 percent greater in mice that both drank caffeine and exercised, when compared to the control group, the researchers say. When combined, caffeine and exercise also “markedly” decreased tissue fat in the mice. More »

      Coffee's Perks Not in the Caffeine

      (Newser) - Scientists have long championed coffee's health benefits, but a series of recent studies is waking them up to the fact that caffeine has nothing to do with it. Regular consumption of coffee or tea can provide protection against cancer, diabetes and heart disease, but researchers say other chemicals are responsible. More »
