Fresh Hurdle for Stem Cell Hunt
from BBC News Online
A Nobel Prize-winning scientist says it could be tougher than first thought to harness the healing power of stem cells in medicine.
It had been hoped a single "master" cell could potentially be used to repair all damage in a single organ. Professor Mario Capecchi, from the University of Utah, found surprising clues that different stem cells might be working together in the same organ.
This means experimental treatments relying on the wrong type might fail. Professor Capecchi, writing in the Nature Genetics, said the finding suggested stem cell biology could be "more complicated" than previously thought, which could be bad news for patients hoping for the swift arrival of new therapies.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
