NOAA Reports No Tornado Fatalities Since March, A Record
No one has died from a tornado since March in the United States--a first since official records began in 1950, according to the NOAA Storm Prediction Center in Norman, Okla. Normally, during the most active tornado months of April, May and June, 61 percent of all tornado fatalities or an average of 52 deaths occur. Research Casts Doubt On Circulating Stem Cells
Although adult stem cells taken from bone marrow are able to migrate into the muscle fibres, they do not generally take on any tissue-specific functions. This result of a study currently being conducted at Bonn's University Clinic means the cells would not serve as a substitute for defective muscle cells. The study is reported in the online section of the science journal PNAS (www.pnas.org, PNAS Early Edition). A New Brake On Cellular Energy Production Discovered
A condition that has to be met for the body to be able to keep warm, move and even survive is that the mitochondria - the cells'power stations - release the right amounts of energy. Scientists have now identified the first known factor that acts as a brake on cellular energy production. Overproducing Leptin Receptors In Fat Cells May Be Key To Halting Weig
A new study by researchers at UT Southwestern Medical Center suggests that when fat cells increase in size -- as they do during the development of obesity -- the cells progressively lose receptors for the hormone leptin, a powerful stimulus for fat burning. US Elections 2008

Most studies of college-student drinking have looked at the individual, and have relied on self reports; New findings gathered from on-the-spot observations show that parties with drinking games can predict higher blood-alcohol concentrations; and young women at theme parties, especially with sexualized themes and costumes, drink more heavily than men. Interestingly, larger parties were associated with less drinking. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Archerfish Tune Their Shots To Universal Properties Of Prey Adhesion
Archerfish exhibit the remarkable ability to hunt for insects and other small terrestrial animals by firing precisely aimed streams of water that knock prey onto the water's surface. These water shots were once thought to be all-or-none in quality, but researchers have now discovered new levels of sophistication in the archerfish's hunting strategy that shed light on how this impressive predatory behavior has evolved. Retinal Stem Cells Can Regenerate After Transplant
University of Toronto researchers have shown that human retinal stem cells transplanted into the eyes of mice and chicks can successfully regenerate. Pre-natal Alcohol Exposure Shapes Sensory Preference, Upping Odds Of L
Young people whose mothers drank when pregnant may be more likely to abuse alcohol because, in the womb, their developing senses came to prefer its taste and smell. Researchers have found that because the developing nervous system adapts to whatever mothers eat and drink, young rats exposed to alcohol (ethanol) in the womb drank significantly more alcohol than nonexposed rats.
