Here is what I am reading today:
“The human ear cannot hear these infrasound signals. However, by playing the data faster than true speed, Georgia Tech faculty member Zhigang Peng increased the sound waves’ frequency to audible levels. The Incorporated Research Institutions for Seismology’s Data Managment Center provided the data.
“The sound started at about 10 hours after the explosion and lasted for another 10 hours in Georgia,” said Peng, an associate professor in the School of Earth and Atmospheric Sciences. He’s confident that the sound is associated with the meteor impact because a slow propagation of the sound waves can be seen across the entire collection of USArray stations, as well as other stations in Alaska and polar regions.”
“”We think this one type of cell may be useful in treating several types of neurodevelopmental and neurodegenerative disorders in a targeted way,” said Arnold Kriegstein, MD, PhD, director of the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research at UCSF and co-lead author on the paper.”
“”The human capacity for complex symbolic math is clearly unique to our species,” says co-author Jessica Cantlon, assistant professor of brain and cognitive sciences at the University of Rochester. “But where did this numeric prowess come from? In this study we’ve shown that non-human primates also possess basic quantitative abilities. In fact, non-human primates can be as accurate at discriminating between different quantities as a human child.””
“”It is unclear why so many physicians who specialize in the management of ADHD — child neurologists, psychiatrists and developmental pediatricians — fail to comply with recently published treatment guidelines,” said Andrew Adesman, MD, senior investigator and chief of developmental and behavioral pediatrics at Cohen Children’s Medical Center in New Hyde Park. “With the AAP now extending its diagnosis and treatment guidelines down to preschoolers, it is likely that more young children will be diagnosed with ADHD even before entering kindergarten. Primary care physicians and pediatric specialists should recommend behavior therapy as the first line treatment.””
“”Athletic participation may prevent involvement in violence-related activities among girls but not among boys because aggression and violence generally might be more accepted in boys’ high school sports,” said senior author Tamera Coyne-Beasley, MD, MPH, FSAHM, FAAP, professor of pediatrics and internal medicine at University of North Carolina at Chapel Hill.”
“”Texting while driving has become, in the words of Transportation Secretary Ray LaHood, a ‘national epidemic,'” said principal investigator Alexandra Bailin, a research assistant at Cohen Children’s Medical Center of New York.
Motor vehicle accidents are the leading cause of death among teenagers, and using a phone while driving significantly increases the risk of accidents in this age group. The specific act of texting while driving has been found to raise the risk of a crash by 23 times, leading many to conclude that texting while driving is more dangerous than driving while intoxicated.”
