Device Offers Hope for Battery-Free Pacemakers
Implantable pacemakers have
been around for more than 50 years, but they've always had one

Daily Aspirin May Help Those at Risk for Recurrent Blood Clots
About a quarter of people who
experience the dangerous blood clots in the legs or lungs known as
venous thromboembolisms (VTEs) develop them for no discernable
reason, and most will receive a powerful anti-clotting drug such as
warfarin in the months after the clot forms.

Approval of the anti-clotting
drug Xarelto (rivaroxaban) has been expanded by the U.S. Food and
Drug Administration to include treating deep vein thrombosis (DVT)
or pulmonary embolism.
