TIDIER HOUSE, FITTER BODY
University suggests that how tidy we keep our home can also indicate how fit we are. That conclusion was based on an examination of the domestic habits of 998 urban African- Americans, ages 49 to 65, that found a correlation between the interior condi- tion, or cleanliness, of a participant’s residence and their level of physical activity. Remarks researcher NiCole Keith, “If you spend your day dusting, cleaning, doing laundry, you’re active.”
A
new study at Indiana
esearchers at Huntsman Cancer Institute at the University of Utah have uncovered new informa- tion about the notion that sugar “feeds” tumors. While it’s accepted that tumor cells use a lot more glucose (a simple sugar) than normal cells, the new study sheds light on how this process takes place and might be stopped. The researchers discovered that during both normal and cancerous cell growth, a cellular process takes place that involves both glucose and glutamine, a common amino acid found in many foods. Glucose and glutamine, both essential for cell growth, were thought to operate independently. This groundbreaking research now shows not only that they are interde- pendent, but that restricting glutamine works to stop the utilization of glucose. Essentially, if glutamine is absent, the cell is short-circuited, due to a lack of glucose; thus, it suggests a new way to halt the growth of tumor cells. The researchers hope that their findings will lead to more effective cancer treatment therapies.

PESTICIDES CAN CONTRIBUTE TO ADHD
A team of scientists from the University of Montreal and Harvard University have dis- covered that exposure to organophosphate pesti- cides may be associated with increased risk of attention deficit hyperactivity disorder (ADHD) in children. Exposure to organophosphates, they report, might affect neural systems in ways that contrib- ute to ADHD behaviors such as inattention, hyperactivity and impulsiveness.

for various ailments, including colds and upset stomachs. Now, researchers at the University of Georgia have found that daily ginger consump- tion also reduces muscle pain caused by exercise. Ginger that’s been heated, as by cooking, might even increase the root’s pain-relieving effects.
