- Green Tea Finds A Tumor Cell
A major antioxidant in green tea binds to a protein on the surface of tumor cells and slows their growth.
- Insight Into Lupus Antigen Protein
These studies suggest how an RNA-binding protein such as La may be involved in the autoimmune response in systemic lupus erythematosus.
- Sex And Brain Gender Differences
Brain regions known to be involved in processing emotionally important stimuli are more activated when men view sexually arousing images than when women do.
- New Technique Tracks Irregular Heartbeats
Scientists report on a new technique for diagnosing and guiding the treatment of heart arrhythmias.
- Stopping Cell Death Speeds Spinal Injury Recovery
Blocking a protein involved in cell death could be one way to treat Spinal cord injuries.
- Protein-Like Polymers
Researchers create a new type of vesicle made of block copolypeptides (polymers made with the same building units as proteins), combining mechanical stability with the ability to open up in response to a specific stimulus -- pH change.
- Faster Road To Inflammation
Cells from arthritic joints make more inflammatory factors because of their response to signals that are normally involved in cell death pathways.
- Honey, I Shrunk The Laboratory!
Researchers have reduced all the components of a molecular biology laboratory needed to isolate genetic material to a chip the size of a dime.
- Hair Springs Eternal
Study shows that stem cells in mouse hair follicles regenerate new hair and hair follicles after being implanted into the skin of mice.
- Grandmas Give Kids A Start In Life
Research may shed some light on why, within the animal kingdom, only in humans do the majority of women live long after menopause.
- Ovarian Transplant Yields Baby Monkey
Fertility researchers have successfully produced a baby rhesus monkey after transplanting part of its mother's ovary to a different site in her body.
- Mouse Ovaries Boast Hidden Reserves
The long-held view that female mammals are born with their lifetime's complement of egg cells may not be correct after all.
- New Smallpox Inoculations Show Promise
Tests of an experimental smallpox vaccine have produced encouraging results in monkeys and mice; the discovery may lead to an alternative for humans unable to receive current smallpox vaccines.
- Cell Double Act Boosts Blood Vessel Production
Researchers have devised a new way to make long-lasting, functional blood vessels in mice; this method may help those who wish to produce artificial vascular networks for human use.
