Cellular cues identified for stroke recovery
...mbination of mitotic, genetic, and viral labeling, tracked newly formed neuroblasts (immature brain cells from which mature adult neurons form) as they traveled through healthy brain tissue to the stroke area. Once there, these immature neurons wrapped themselves around the immature vascular cells that were ...Other highlights in the January 3 JNCI

They also tracked whether it was most effective to inject the liposomes before, during, or before and during heating of the tumor, which triggers the liposomes to dissolve and release the doxorubicin inside.

... insect bodies and passerine muscular tissues were tracked throughout the year, serving as a control. The results elegantly showed that the bats ate only insects in summer, included some songbirds' flesh in their diet during spring, and depended a great deal on passerines during autumn.
