New Approach to Stroke Therapy

LMU researchers developed a new strategy for the treatment of stroke, which could help to improve blood flow to ischemic brain. Strokes are due to a localized reduction in the blood supply to the brain, mainly due to the blockage of a vessel by a blood clot. This can lead to the death and irreversib...

New 3-D Stem Cell Culture Method Published in JoVE

Stem cells are the body's mechanics, repairing damaged tissues and organs. Because these cells are able to grow into any type of cell in the body, scientists believe they hold the key to groundbreaking new therapies. To help further this research, scientists from the University of Victoria have foun...

Study by UC Santa Barbara Researchers Suggests That Bacteria Communicate by Touch

What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions. The findings appear today in the journal Genes & Developm...
