Kilimanjaro ice reveals devastating history, future

Researchers analyzing ice cores taken from Tanzania's Mount Kilimanjaro say they've found evidence of several catastrophic droughts that plagued the tropic over the millennia, and strong signs the ice field itself will disappear within 20 years, the victim of global warming.

Valium-like drug helps treat lupus

A cousin to the anti-anxiety drug Valium has been shown in mice to reduce some of the symptoms associated with lupus. Lupus is an autoimmune condition in which the immune system attacks the body's own tissues. "The best available therapies for lupus haven't changed for many, many years," says U-M's Gary D. Glick, Ph.D., one of the lead authors on the study. "It's a disease where the mechanisms that normally prevent the immune system from attacking components of one's own body are defective. Because we do not yet understand what triggers lupus, it has been very difficult to develop lupus-specific therapies."

Now for something really important ... pork!

Injecting me with bicarbonate of soda makes me ever so much more delicious Treating pork and other livestock meat with plain old baking soda improves the taste, Wisconsin researchers have found. "For years consumers have noticed that pork quality is inconsistent. A major reason is that the meat from some pigs becomes pale, soft and watery after they are slaughtered, according to Robert Kauffman, an expert on pork quality and a UW-Madison emeritus professor." Vegetarians in the audience should move on now, as this clearly meat-friendly story may make you a little uncomfortable.

Vet develops cheap manatee chow for injured animals

Must be the manatee chow Fifty pounds of romaine lettuce makes enough Caesar salad for a hundred people, but it?s just a one-day food supply for a manatee in captivity. To feed the endangered aquatic mammals more economically while they recover from injuries or medical treatment, a University of Florida veterinarian has developed a new manatee chow that costs one-tenth the price of lettuce. The discovery comes at a time when manatee injuries and subsequent deaths have reached record rates. In 1986, 122 manatees died in Florida. Fifteen years later, that number climbed to 325.

Coenzyme Q10 slows Parkinson's in study

High doses of the naturally occurring compound coenzyme Q10 has been found to slow by 44 percent the deterioration in function that occurs in Parkinson's disease. The greatest benefit was seen in everyday activities like eating, dressing, bathing and walking. But researchers say that before people run out to RightAid for a barrel of the stuff, a wider study is needed (this one tracked 80 patients). Parkinson?s is a degenerative disorder of the brain in which patients develop tremor, slowness of movement and stiffness of muscles. It affects about 1 percent of Americans over the age of 65.

Bloodworm shows new use for copper

No other worm looks like it, or lasts like it The lowly and somewhat gruesome bloodworm may have a few lessons to teach material scientists.The critter apparently is the first ever to be found to use a copper-containing mineral structure as part of its skeleton. The finding is remarkable first because the amount of copper detected in the jaw tip of the marine worm would normally be toxic to an organism. Second, the copper also occurs in non-mineral form in the bloodworm jaw where it may act as a sort of bridge, cross-linking long chains of fibrous proteins. And that has appealing commercial posibilities. "The marriage of protein with copper mineral as well as with bound copper ions is an intriguing concept per se but may also serve as a design prototype for new materials that need to be hard, lightweight, and durable."

Broccoli not always so healthy, researchers find

It probably won't get you off the hook with mom, but researchers say that the nutritional content of broccoli tends to fluctuate wildly. While a single serving from one head could pack enough antioxidants and cancer fighters to keep you going for a few days, eating an entire other head could do bupkus.

Fat cells converted to bone

Pre-cells destined to become fat can be converted instead into true bone cells in
response to outside signals, say researchers at the University of California, San Francisco. The finding could pave the way for scientists to replenish lost bone cells in patients with conditions like osteoporosis, and to help repair bone defects. The new bone cells have all the hallmarks associated with mature bone formation, including production of bone proteins and calcification, the UCSF team says.
