Since the end of the Space Shuttle flights, NASA has been relying on help from Russia to launch men and women into space. The agency has been planning on replacement rockets to take humans into space and now engineers have taken a crucial step in preparing to test parts of NASA's Space Launch System (SLS) rocket that will send humans to new destinations in the solar system. They installed on Thursday an RS-25 engine on the A-1 Test Stand at the agency's Stennis Space Center near Bay St. Louis, Mississippi.

Los residentes de California han estado notando algo desconcertante cuando llegan a la tienda de abarrotes este año: es un año terrible para las frutas con hueso. A pesar del hecho de que estamos en plena canícula, los duraznos, nectarinas, albaricoques, ciruelas, cerezas y similares son mucho más caros que usualmente, y encima son de mucha menor calidad. ¿Qué está pasando? La respuesta está en la sequía extrema del estado, lo que causó estragos en numerosos cultivos de este año, incluyendo la fruta con hueso. La agricultura del estado puede estar experimentando algunos cambios importantes que se verán reflejados el año que viene, gracias al cambio climático y los cambios naturales en los niveles de lluvia, y no es la única región con miras de un futuro más seco.

Thought to dwell mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals. "So little is known about these rays," said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. "We thought they probably travelled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise."
