Protein completely restores motor function; scientists hope it will help humans People with impaired mobility after a stroke soon may have a therapy that restores limb function long after the injury, if a supplemental protein works as well in humans as it does in paralyzed rats. Two new studies by UC Irvine biologists have found that a protein naturally occurring in humans restores motor function in rats after a stroke. Administered directly to the brain, the protein restores 99 percent of...

A resilient rodent from the horn of Africa has begun charming scientists around the world.  Resistant to cancer and aging better than Sean Connery, the remarkable, if somewhat unattractive, naked mole rat is proving to be a biological wonder and a new source of scientific inquiry. "They really are from Mars, I think," Thomas Park, biological sciences professor at the University of Illinois at Chicago, told the Associated Press. Able to live up to 30 years, these 3 to 4 inch East African...

Eat those naughty, high calorie foods! A high-fat, high-sugar diet has now been shown to affect the brain the same way as mood-altering drugs, Australian researchers announced on Tuesday. In a recent investigation, rats - traumatized when young and exhibiting signs of depressed behavior - were fed lard-laced foods like sweets. The results suggested these foods decreased the rats' stress levels. "We asked the question, if you're stressed early in life and then you're given yummy food to eat...

Human activities have meant invasive species have been able to populate parts of the world to which they are not native and alter biodiversity there over thousands of years. Now, an international team of scientists has studied the impact of the black rat on bird populations on Mediterranean islands. Despite the rat's environmental impact, only the tiny European storm petrel has been affected over time by its enforced cohabitation with the rat. A European team has studied around 300 islands in...

Rat Island, Alaska, may get its Aleut name back now that the rats for which it was named seem to be gone, scientists from a polar marine program said. A $3 million eradication program appears to have rid the island of rats for the first time since the late 1700s, said Steve MacLean, polar marine program director for The Nature Conservancy in Alaska, one of the partners in the eradication program. A year ago, crews dropped 700 pounds of poison-laced pellets on the island, McClatchy Newspapers...

Exercise is always being advised for good health but a study in rats found extreme exercise may be physically addicting, U.S. researchers found. Lead author Robin Kanarek of Tufts University said excessive running shares similarities with drug-taking behavior. As with food intake and other parts of life, moderation seems to be the key, Kanarek says in a statement. Exercise, as long as it doesn't interfere with other aspects of one's life, is a good thing with respect to both physical and...

Alaska's Rat Island is finally rat-free, after a Japanese shipwreck spilled rampaging rodents onto the island 229 years ago, decimating the local bird population. According to the U.S. Fish and Wildlife Service, after dropping poison last autumn onto the island from helicopter-hoisted buckets for a week and half, there were no signs of living rats and some birds returned. Rats have ruled the island since 1780 when they jumped off a sinking Japanese ship and terrorized all but the largest...
