Computer scientists' new tool fools hackers into sharing keys for better cybersecurity
Instead of blocking hackers, a new cybersecurity defense approach actually welcomes them. The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders into a decoy site so the computer can learn from hackers' tactics. The information is then used to train the computer to recognize and stop future attacks.

Team deciphers how myotonic dystrophy generates lethal heart dysfunctions
Roughly 80% of people with myotonic dystrophy — a common form of muscular dystrophy — experience dangerous heart ailments, and heart rhythm defects are the second-leading cause of death in those with the condition. In a new study, researchers traced the molecular events that lead to heart abnormalities in myotonic dystrophy and recreated the disease in a mouse model.
