New biochip technology could eliminate animal testing in chemicals and cosmetics industries

A new biochip technology could eliminate animal testing in the chemicals and cosmetics industries, and drastically curtail its use in the development of new pharmaceuticals, according to new findings from a team of researchers at Rensselaer Polytechnic Institute, the University of California at Berkeley, and Solidus Biosciences Inc.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Genetic cause of Kawasaki disease

Researchers from Japan's RIKEN SNP Research Center, collaborating with a team at the University of California, San Diego (UCSD), have discovered a new genetic variation that affects a child's risk of getting Kawasaki disease (KD), an illness characterized by acute inflammation of the arteries throughout the body.

Complex path to cell death shown by identification of new genes

Can a tiny winged insect's salivary glands really tell us about processes relevant to human disease? Yes, according to a new study by researchers at the University of Massachusetts Medical School (UMMS), who gained new insights into autophagy - a cellular degradation process associated with a form of programmed cell death - by studying the salivary gland cells of the fruit fly.

How molecular muscles help cells divide

Time-lapse videos and computer simulations provide the first concrete molecular explanation of how a cell flexes tiny muscle-like structures to pinch itself into two daughter cells at the end of each cell division, according to a report in Science Express.

Tumors less than 1 centimeter in size can be aggressive and may require maximum therapy

Breast tumors that are 1 centimeter in size or smaller - no more than 0.4 inch in length - can still be very aggressive and may require more intensive therapy than is routinely offered today, say researchers at Mayo Clinic in Jacksonville, Fla.
