    Researchers are developing methods for inactivating all sorts of pathogens that could be found in blood, including West Nile virus, an emerging infection recently brought to the United States from Africa.

  3. Health & Medicine

    In Silico Medicine

    Medical researchers are increasingly turning to computer simulations to help them understand the complexity of living systems, design better drugs, and treat patients more effectively.

  4. Health & Medicine

    Keeping the beat

    Muscle cells taken from embryonic rats and put into an adult rat's heart can transmit the electric signals that govern the heartbeat.

  5. Tech

    Robotic heart surgery

    By using robotic rather than conventional open-heart techniques, doctors can perform heart surgery with smaller incisions, giving patients less pain and speeding recovery.

  6. Health & Medicine

    Cycling and surgery have similar effect

    Among people with chest pain because of clogged heart arteries, regular exercise on a stationary bike reduced symptoms better than surgery did.

  7. Health & Medicine

    A hot new therapy?

    Spending time in a sauna improves heart function in people with chronic heart failure.

  8. Health & Medicine

  12. Health & Medicine

    Nervous tics in the heart

    The irregular heartbeats sometimes triggered after a heart attack may be caused by abnormal nerve growth in heart tissue damaged by the attack.
