Countries in sub-Saharan Africa have made remarkable progress towards reaching universal school enrollment in the past 25 years.

In a new study in mice, a team of researchers from UCLA, the Swiss Federal Institute of Technology, and Harvard University have uncovered a crucial component for restoring functional activity after spinal cord injury. The neuroscientists have shown that re-growing specific neurons back to their natural target regions led to recovery, while random regrowth was not effective.

People in poorer countries are disproportionately suffering from air pollution spewed from the increasing scourge of fires in forests and fields around the world, according to new research published Wednesday.
