human heartCardiac surgeon and his colleagues have developed a biodegradable adhesive that can patch a hole in a pig's heart or artery.

Justice Dept. opposes block on contraceptive mandate

us justice dept.The Obama administration on Friday called on Supreme Court Justice Sonia Sotomayor to lift her order temporarily blocking a part of the president's signature health care law that requires some religious-affiliated organizations to cover forms of contraception in their health care plans.
