Seismology highlights from BSSA February issue
Feb. 5, 2010 (San Francisco, CA) -- A new study identifies earthquakes through July 2007 that have produced 100 of the strongest peak accelerations (PGA) and 100 of the strongest peak velocities (PGV) ever recorded. The threshold for the first list is acceleration of the ground exceeding 7.31 m/s2 (74% of gravity), while the threshold for the second is velocity exceeding 0.65 m/s. Crustal earthquakes dominate the lists. Exceptionally strong ground motions exceeding these levels have been observed on sites with the softest soils and sites with the hardest rock.

Extremity war injuries symposium seeks to improve patient care for wounded warriors
WASHINGTON, D.C. - Since the beginning of Operations Iraqi Freedom and Enduring Freedom, there have been nearly 36,000 battle- injured warriors, of which approximately 82 percent suffer extremity trauma. Many of these injuries are complicated by the effects of improvised explosive devices which cause injury patterns distinct from civilian trauma. Traditional wound-management guidelines simply fall short. In an effort to address the increasing number and severity of extremity war injuries among the nation's warriors serving in Iraq and Afghanistan, the American Academy of Orthopaedic Surgeons (AAOS), the Society of Military Orthopaedic Surgeons (SOMOS), the Orthopaedic Trauma Association (OTA), and the Orthopaedic Research Society (ORS) will bring together the nation's top civilian and military orthopaedic trauma surgeons and researchers for a two-day symposium January 27 - 29 to discuss barriers of return of function and duty and develop treatment principles.

Bypass procedure used during infant heart surgery does not impair later neurological outcomes
Congenital heart defects (CHD) are the most common birth defects in humans, affecting 8 per 1000 live births with one third of affected children requiring intervention in early infancy. Increasing numbers of survivors combined with developmental expectations for independence, behavioral self-regulation and academic achievement have led to a growing identification of neurobehavioral symptoms in some survivors. A study now suggests that a cooling technique often used in heart operations does not impair neurological outcomes.
