BY NATHAN WARTERS / THE FREE LANCE-STAR When she first tried out for the United States Deaf Women’s National Soccer team, Sabrina Hernandez begged her mother to take her home. She was only 12 at the time, and she wasn’t comfortable around the older players. Hernandez laughs at the memory now. It seemed so long ago that she felt like an outsider among all those college- and professional-level players. Now she calls them teammates. “They don’t care what your age is. They care if you can play soccer the right way and if you can have fun playing soccer,” said Hernandez, 14. Hernandez, an eighth-grader at Caroline Middle School, was recently named to the deaf women’s national soccer team. The 15-person squad, of which Hernandez is the youngest, will soon be on its way to the Deaflympics, which will be held from July 26–Aug. 4 in Sofia, Bulgaria. Being the youngest player on the team has its challenges, but those pale in comparison to what Hernandez has overcome in her young life. Because of underdeveloped cochlea, she was born with 85 percent hearing loss in her right ear and 45 percent hearing loss in her left. Hearing loss hasn’t prevented Hernandez from doing extraordinary things in her life. She is extremely ambitious and communicates well—she is insightful and chatty—with the help of hearing aids. “She is a straight-A student. She’s in the Beta Club. She’s in the National Junior Honor Society, also. She’s always trying to get int ...

Earthquakes that break seismic sound barrier confirmed in lab experiments

The inner workings of bizarre and potentially dangerous earthquakes that break the seismic sound barrier have now for the first time been confirmed in laboratory experiments with real rocks, report scientists in today's issue of the journal Science. What are called supershear earthquakes are strange events in which the rupturing fault breaks faster than certain seismic waves can travel, creating a sort of seismic mach cone that fires out the end of a fault's rupture zone -- the part of the fault that breaks loose allowing two rock surfaces to jerk past each other. That cone and the waves that follow can cause inordinately severe shaking, out of proportion to the earthquake's magnitude. "It's like the (seismic) waves are propagating along and all of a sudden it steps on the accelerator," explained Eric Dunham, an assistant professor and seismological researcher at Stanford University who has done modeling work on supershear waves. ...
