Now researchers at the UCSD Cancer Center have discovered a fundamental basis for drug resistance, which they report in the June 24 issue of the journal NATURE. The team discovered a signaling pathway that is activated by the chemotherapy drug cisplatin. Drug resistance occurs when this pathway is defective.

A hundred years ago, John Philip Sousa was the most popular musician in America, and not just because marches were more popular then. "Sousa's secret," says the leader of the Blawenburg Band, and a professor of music at Rider University in Lawrenceville, NJ, "is simple, but often lost on people who people who put together programs of orchestral music today."
Many urban Kansans arrange their vacations around the wheat harvest so that they can help on a family's or friend's farm. A handful of University of Kansas faculty and staff members with roots entrenched in farming return to homesteads each summer to help in the fields.
Looking deep within the genes of three very different kinds of animals, scientists have found enough molecular evidence to finally fell the animal kingdom's old family tree.
Green watermelons--a serious economic threat to farmers and a disappointment for consumers--may be quickly and automatically rejected by a new machine invented by four University of Delaware engineering students. The computer-controlled ripeness sensor ultimately could result in huge savings for the global watermelon industry.
Expanding educational and sports opportunities for girls and women around the world is the theme of the 50th anniversary conference of the International Association of Physical Education and Sport for Girls and Women (IAPESGW), a conference expected to draw 100 of the world's most influential women in sports and physical education to Smith College July 7
In 1996, uninsured people with HIV waited up to four and one-half months longer, than privately insured patients to begin AIDS cocktail drugs; HIV patients covered by Medicaid waited three months longer, blacks started nearly three months after whites, and women began about two months later than men. But disparities are narrowing.
Dallas -- A simple 30-minute test may soon be a safer and more convenient way to diagnose coronary heart disease, the cause of heart attacks, than the widely used invasive technique of X-ray angiography, researchers report today in Circulation: Journal of the American Heart Association.
The incidence of serious knee injuries among female athletes at the high school and college level is four to six times higher than that of their male counterparts.

Six years ago, an economics journal suggested that milk producers who pay "check-off" allocations may be better served spending that money on research, rather than on milk promotion and marketing. Now, Cornell University agricultural economists say that the mathematical model used in that study may be incorrect due to erroneous assumptions, and in some cases money spent on consumer promotion will pay off better.
