Bystander CPR helps cardiac arrest survivors return to work

A Danish study found that more than 75% of out-of-hospital cardiac arrest survivors returned to work, with a significant increase in return-to-work rates among those who received bystander CPR. The study also revealed that survivors spent an average of three years back at work and earned the same salary after arrest.

Researchers 'un-can' the HIV virus

A new approach to fighting HIV has been discovered by researchers at the University of Montreal, who identified a way to use a tiny molecule to 'open up' the virus and expose its vulnerable parts. This breakthrough could lead to the design of a vaccine to prevent transmission and potentially one day eradicate the virus.
