12:02 AM | Beets for Speed and Power. Walnuts for Endurance.
The idea that beets increase speed and power during exercise performance is pretty new.  Beets are rich in anti-oxidants, but they are also high in nitrate.  Until recently nitrate was thought to be nothing but a problem.  Nitrate interferes with iodine uptake, so it could contribute to iodine deficiency.  There are also associations between high […] The post Beets for Speed and Power.

7:29 PM | Research on flies suggests that lost stem cells are naturally replaced by non-stem cells
Erika MatunisCreditJohns Hopkins researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies, when a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.The discovery sheds light on the tiny "environments" that stem cells occupy in animal bodies and may help explain how stem cells in tumors replenish themselves, the researchers report in the May 8 issue of the journal Cell […]

7:17 PM | Mesenchymal stem cells require hydrogen sulfide to function properly
Professor Songtao ShiMesenchymal stem cells need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study from the Center for Craniofacial Molecular Biology at the Ostrow School of Dentistry.Professor Songtao Shi, principal investigator on the project, said the presence of hydrogen sulfide produced by the cells governs the flow of calcium ions. The essential ions activate a chain of cellular signals that results in osteogenesis, or the creation of […]
