Items Listed In The News Category:Studying the Genetic Component in LongevityScientists are reporting the results of a detailed study on the gene-expression patterns in C. elegans with and without mutated daf-2 genes, which affects longevity. The mutated daf-2 gene leads to a doubling in lifespan. The research shows that several metabolic processes are repressed by the presence of the mutated gene. MORE... Vitamin D and Calcium Supplements Failed to Prevent FracturesIn a blind study of more than 5,000 persons over the age of 70, researchers failed to find any significant effect from taking daily supplements of 1,000 mg calcium and/or 800 i.u. vitamin D3. The main thrust of the study was to examine the incidence of bone fractures due to osteoporosis, but they also looked at mortality, frequency of falling and quality of life. MORE... Scientists put Mice in Hibernation-Like StateScientists report the first successful attempts to induce a hibernation-like state in mice, and hope the simple process used will work on larger mammals and even humans. Simply spiking the air with a preponderance of hydrogen sulfide put the mice into a lowered metabolic state, and returning normal air revived them. If this process works on humans it could have numerous medical applications, allowing doctors to \'buy time\' in crisis situations. MORE... |
