Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

U.S. Judge approves federal funding for embryonic research

Federal funding of human embryonic stem cell (hESC) research is now legal in the United States. Chief judge of the US District Court for the District of Columbia Royce Lamberth has ruled on the case Sherley et al. v. Sebelius, in favor of hESC research. This overturns an existing law that prohibits the government from funding research that destroys the embryo.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Report on versatility of nitric oxide in arming hosts against pathogens

A new target for nitric oxide has been revealed in studies of how it inhibits the growth of Salmonella. This bacterium is a common cause of food-poisoning.

Strategies toxins use to invade human host cells

Toxins produced by plants and bacteria pose a significant threat to humans, as emphasized by the recent effects of cucumber-borne Shiga toxin in Germany. Now, new research published on July 21st by the Cell Press journal Developmental Cell provides a clearer view of the combination of similar and divergent strategies that different toxins use to invade a human host cell.

Caffeine reduces women's chances of becoming pregnant

Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb. "Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman's chance of becoming pregnant," says Sean Ward, professor of physiology and cell biology, at the University of Nevada School of Medicine, who conducted the study.

Scientists define structure of astrovirus that causes juvenile diarrhea

Rice University scientists have defined the structure -- down to the atomic level -- of a virus that causes juvenile diarrhea. The research may help direct efforts to develop medications that block the virus before it becomes infectious.

Nano-patterned plastic to advance stem cell research

Scientists have developed a novel plastic surface which overcomes the difficulties associated with growing adult stem cells. Standard surfaces have proved limited for growing large amounts and retaining the stem cells' useful characteristics. This discovery could lead to the creation of stem cell therapies for re-growing bone and tissue, and also for conditions such as arthritis. The study was carried out by Glasgow and Southampton universities.

New animal model for studying development of testicular germ cell tumors

A team of researchers from Spain and Switzerland have developed a new model for studying the development of testicular germ cell tumors by transplanting embryonic stem cells into the seminiferous tubules in mouse models, resulting in the development of testicular germ cell tumors (TGCT) that mimic the early stages of TGCT development.
