Crab shells help spinal injury?

By | April 19, 2010

Material from crushed up crab and shrimp shells can restore electrical function to damaged guinea pig spinal cords, suggesting it may one day serve as a treatment for spinal cord injuries, according to a study published April 16th in the Journal of Experimental Biology. This paper is an "intriguing first step," said linkurl:Scott Whittemore,; professor of neurological surgery at the University of Louisville, who was not involved in th

Catastrophic art

By | April 16, 2010

When artists Jebney Lewis and K.R. Wood asked University of Pennsylvania mathematical biology postdoc Todd Parsons for a complex concept that needed to be communicated to the broader public, it was hysteresis: the idea that seemingly gradual change can suddenly become catastrophic. Over dinner, pad of paper and pencils in hand, the three started brainstorming ways to visually embody the slow growth and sudden collapse. Several months and many sketches later, their work is now on display as an


NIH funding rates drop

By | April 15, 2010

Last year, the NIH funded fewer grants than it has for any year in the last nine years, and the average grant success rate -- 20.6 percent of reviewed grant applications funded among 26 institutions -- was the second lowest since 2000. Success rates are down from 21.8 percent in 2008 and only slightly higher than the 2006 ten-year low, when the NIH dispersed its funds out among only 20.0 percent of reviewed proposals. In total, 8,881 grant applications were funded last year, down from 9,460

Nuclei swap to stop disease?

By | April 14, 2010

A technique may one day prevent something that is currently unpreventable -- the transmission of mitochondrial diseases from mother to child, according to a proof-of-concept paper published online today (April 14) in Nature.

Top killers share genes

By | April 12, 2010

Cancer, obesity, and even atherosclerosis share a common set of differentially expressed genes, suggesting a diverse number of human diseases share the same disrupted biological pathways, according to new research published this week in Cancer Cell. The genetic link also suggests that drugs currently used for the treatment of metabolic and cardiovascular diseases might also be used against cancer, researchers say.
