Protein found to control tumor growth in certain breast cancers

...and will hopefully stimulate researchers to take a fresh look at the Nod1 protein." In the study, researchers looked at a number of biological processes where Nod1-dependent apoptotic (programmed cell death) pathways were a critical component, including the regulation of tumor cell growth where the fai...

US woman gives birth to baby from world's first frozen donor egg bank

...nd difficult path. Many problems that exist with fresh donor eggs such as synchronizing the donor's cycle with the cycle of the infertile woman are virtually eliminated with frozen donor eggs from the CEI bank. Frozen donor eggs, like frozen sperm, offer unprecedented convenience, eliminating geographica...

Ancient fossil DNA found preserved in crystal

...irst reported the existence of crystal clusters in fresh bones. Even when these bones are ground up and treated with sodium hypochlorite ?a substance that removes all traces of organic matter ?the clusters of crystals remain intact and the organic material embedded in them is unaffected. Now, almost 20 yea...

History of human cannibalism eats away at researchers

...niversitat Pompeu Fabra, and his colleagues used a fresh set of genetic data to show that balancing selection associated with cannibalism has not been a major selective driving force on the prion protein gene, as has recently been proposed. Their work also has important scientific implications for researc...

Relic of life in that Martian meteorite? A fresh look

...hysical Laboratory, with colleagues,1 have taken a fresh look at how material associated with carbonate globules was created using sophisticated instrumentation and they compared the results to analogous globules from a volcanic complex on Svalbard, an island north of Norway. It does not appear that living...
