Low Iron Levels Cause Weakness In Women Who Are Not Anemic
.... Since studying women working in fields would be too
difficult, they assessed the physical performance of women working out on exercise bikes. First, they compared 15 normal women with 15 iron-depleted non-anemic women exercising at their maximum level of effort. They found that iron-depleted women ha...

little dopamine contributesto a reduction of motor function and executive abilities (planning and attention). "We thought that we might see reduced motor function," shesaid. "At this point, however, it doesn't look like it. We've onlylooked at two o...

much out of the RNA, or pastedthe remainingRNA together wrong. Normal and fetal cells made the same mistakes, but muchless often. "The earlier report of TSG101 deletions was actually detecting this alteredsplicing," saysFeinberg. "Is this ...
New Gene May Intensify Breast Cancer Growth
...of Intramural Research, at the NIH. The finding is too
new to have an immediate impact on breast cancer therapies."At this early stage, we're really thinking more in terms of the fundamentalcell biology of breast cancer. We think this gene is probably part of the enginethat drives the growth of some brea...
Roadsides Benefit From Waste, UF Researchers Say
..."They're everywhere." In general, roadside soil is too
sandy to hold nutrients or water, making it difficult for grass to grow well. Importing topsoil and adding commercial fertilizer helps but is prohibitively expensive. So the researchers turned to organic wastes. "The roadside is a very harsh conditio...
