Tissue-specific adult stem cells are responsible for the ability of mammals to re-grow the tips of fingers or toes lost to trauma or surgery, say researchers at the Stanford University School of Medicine. The finding discredits a popular theory that holds that previously specialized cells regress, or dedifferentiate, in response to injury to form a …
In the new study, Elimelech and William Phillip, now at the University of Notre Dame, demonstrate that reverse osmosis requires a minimum amount of energy that cannot be overcome, and that current technology is already starting to approach that limit. Instead of higher water flux membranes, Elimelech and Phillip suggest that the real gains in …
Based on our (Royal Bank of Canada) analysis, only 26 million pounds of additional uranium can be brought into production between $40 per pound and $60 per pound and an incremental 60 million pounds can be added at prices between $75 per pound and $90 per pound The Royal bank is still projecting increases in …
