5 studies you may have missed

Here's a roundup of five medical studies published this week that might give you new insights into your health, mind and body. Remember, correlation is not causation – so if a study finds a connection between two things, it doesn't mean that one causes the other.

1. Surgical glue may mend broken hearts
Journal: Science Translational Medicine

Doctors see a huge unmet need for better adhesives in medicine, says Jeff Karp, co-director of the Center for Regenerative Therapeutics at Brigham and Women’s Hospital in Boston. The current options include sutures, which can be time-consuming to insert, and staples, which can do significant damage.

Karp and colleagues wanted to develop a better adhesive solution for babies with congenital heart defects who require surgery. To create an adhesive that would work on a beating heart in the presence of blood, a material would have to be biodegradable, elastic and nontoxic.

Researchers turned to nature for answers, observing how creatures such as sandcastle worms and spiders "have secretions that enable them to attach to wet surfaces," Karp said.
