Chemical 'crumbs' from microbes' snacks provide a trail to ancient, remote life

...ies and knows where the goodies are kept, then the missing cookies and the crumbs would implicate him as the midnight snacker. Anbar's team found an "imposter," a chemical process that doesn't necessarily involve any living organisms but nevertheless leaves evidence that scientists had thought might only be...

Genes for unusual flower within a flower are identified by UCSD scientists

...f the flower organs. "This discovery may add the missing piece of the puzzle, as we now know that these genes are necessary for the formation of the different flower organs," says Yanofsky.

Asprin-like drugs may be useful for cancer treatment, study suggests

...ssels, a process called angiogenesis. In the cells missing the COX-2 gene, VEGF levels were substantially lower; with an active COX-2 gene, VEGF levels dropped after treatment with COX-2 inhibitors. "It appears that the inhibition of tumor growth is due to lack of tumor-associated angiogenesis," said Raymon...

Prosthetic limb to be controlled by microchip: Agreement signed to create smart leg

... "This is about making a leg that is more like a missing limb than a collection of components ever can be," says Diane Hurtado of the Smart Integrated Lower Limb (SILL) project team. "This limb will have a digital control system to make it smart." Says Ivan Sabel, president of Hangar, of which SOGI is a...

Sense of touch/nerve research

...dual nerve fibers were examined. Strikingly, mice missing the protein showed a very specific and selective deficit in one type of touch perception; rapidly adapting mechanoreceptors were much less sensitive. These fibers sense very light touch. "The BNC1 protein is an ion channel located at the tips of n...
