...ards? Fear not. In a comprehensive study of 25 men competing in an Ironman, Austrian researchers uncovered some startling physiological insights into training and recovery from the combined effects of swimming 3.9 kilometers (2.4 miles), cycling 180.2 km (112 miles) and then running the standard marathon dista...Rochester scientists develop fast-working biosensor

The technology potentially could detect any biological entity, Miller said. A physician someday, for example, could use the technology in his office to confirm a streptococcal......t? Biologists have come up with a wide variety of competing (and, in some cases, complementary) hypotheses to explain why sex continues to exist in the midst of recurrently evolving asexual competitors. The most widely accepted explanation has been that sexual reproduction confers the benefit of "unlinking" g...UCLA engineering and Mattel Children's Hospital collaborate to develop children's heart valve

Thin film nitinol could allow doctors at UCLA to make a transcatheter heart valve suitable for use even in small children.
