New technology for keeping liver cells alive inside bioartificial liver-assist devices
http://www.news-medical.net/?id=29075
Such devices enable people who are suffering from acute liver failure to survive while their own liver cells regenerate, or until they receive a liver transplant. The person's blood or plasma circulates through the device. Inside, living cells -- usually pig or human liver cells -- perform normal liver functions.

Techniques that improve people's comprehension
http://www.news-medical.net/?id=29093
People have incredible amounts to learn throughout their lives, whether it be preparing for a test in middle school or training for a new job late in life. Given that time is often at a premium, being able to efficiently learn new information is important.
