A jellyfish may be able to help human heart patients.
Researchers from Cal-Tech and Harvard created a free swimming artificial jellyfish.
They built it using silicone as a base to grow heart muscle cells harvested from rats..
And used electric current shock into making it swim with synchronized contractions that mimic real jellyfish.
Researchers say the breakthrough could lead to new heart treatments for humans.
HIV and Cervical Cancer
Infection with the virus that causes aids does not appear to increase a woman's risk of cervical cancer.
Researchers looked at more than 400 HIV infected women and 300 without the virus.
All had a normal pap test and a negative result for the human papillomavirus at the start.
After five years of follow-up, the risk of cervical pre-cancer was similarly low for both groups.
YouTube and Vertigo
Video sharing websites are being used to help people with a certain type of vertigo.
Researchers reviewed more than 3300 YouTube videos on a procedure called the Epley Maneuver.
This helps people with benign paroxysmal positional vertigo -- an inner-ear disorder that causes dizziness.
Although video sharing works for one type of vertigo, doctors say it should never take the place of seeing a doctor in person.
