Test flight of Virgin Galactic spaceship ends in fatal crash in California

Wreckage from Virgin Galactic's SpaceShipTwo is shown in this still image captured from KNBC video footage from Mojave CaliforniaBy Alex Dobuzinskis MOJAVE Calif. (Reuters) - A passenger spaceship being developed by Richard Branson?s Virgin Galactic company crashed during a test flight on Friday near the Mojave Air and Space Port in California, killing one pilot and seriously injuring the other, officials said. The crash of the suborbital vehicle, undergoing its first powered test flight since January over the Mojave Desert, 95 miles (150 km) north of Los Angeles, came days after another private space company, Orbital Sciences Corp, lost a rocket in an explosion moments after liftoff in Virginia. ...

U.S. rocket explosion investigation suspects main engine failure

An unmanned Antares rocket is seen exploding seconds after lift off from a commercial launch pad in this still image from NASA video at Wallops IslandBy Irene Klotz CAPE CANAVERAL Fla. (Reuters) - As Orbital Sciences picks up the pieces, literally and figuratively, after its high-profile rocket launch explosion, accident investigators are looking closely at a potential first-stage engine problem. Technical data relayed from Orbital?s Antares rocket before and after Tuesday?s liftoff from Wallops Island, Virginia, show everything was fine until the rocket?s ascent stopped 15 seconds into the flight, the company said in a status report issued late Thursday. ...

NASA handout photo of an aerial view of the Wallops Island launch facilities in Wallops Island, VirginiaBy Irene Klotz CAPE CANAVERAL Fla (Reuters) - Heeding a lesson from history, designers of a new generation of U.S. rockets will include escape systems to give crew members a fighting chance of surviving launch accidents such as the one that felled an unmanned Orbital Sciences Antares rocket on Tuesday. The U.S. space agency NASA bypassed escape systems for the now-retired space shuttle fleet, believing the spaceships to be far safer than they turned out to be. The illusion was shattered on Jan. ...

Boeing exec says NASA crash underscores need for new U.S. engine

By Andrea Shalal WASHINGTON (Reuters) - The crash of an unmanned Orbital Sciences Antares rocket is a "wake-up call" to the U.S. space community about the need to develop a new U.S. rocket engine, the head of Boeing Co's defense division said on Thursday. Chris Chadwick, chief executive of Boeing Defense, Space and Security, said the failure of the rocket on Tuesday was a "sad and tragic" reminder that the space business was complex and difficult, but he did not expect a lasting setback to the overall industry. The incident underscored growing concerns about U.S. ...

Skin-eating Asian fungus imperils world's salamanders

An international research team said on Thursday the fungus, first detected in Europe last year, has killed salamanders in the Netherlands and Belgium and is expected soon to reach other European nations. They said it is closely related to another fungus that already has wiped out some amphibian species. ...

Rare Look Inside Tiny Mouth Wins 'Small World' Photo Contest

Rare Look Inside Tiny Mouth Wins 'Small World' Photo ContestIn a photo contest that honors all things small, it's tough to beat a shot of a rotifer: A view into the mouth of one of the tiniest animals on the planet won the top prize in this year's Nikon Small World competition. Rotifers rank among tardigrades as the smallest creatures in the animal kingdom. The winning photo, captured by Rogelio Moreno, a programmer and self-taught microscopist from Panama, shows the open mouth of a rotifer surrounded by a heart-shaped corona, or a crown of cilia that sweep water into its maw. Moreno watched the rotifer for hours, waiting for the right opportunity to snap a shot of the constantly moving creature at the moment it opened its mouth, according to Nikon.

Her tidal simulation units could be an important tool for preserving and restoring environmentally important wetlands, because they enable researchers to investigate tidal marsh plant growth in a controlled setting.

A common complication, gestational diabetes affects approximately 6-7% of pregnant women. Currently, screening is done in two steps to help identify patients most at risk; however, the suggested levels for additional testing were based on singleton pregnancy data. Now investigators have analyzed data from twin pregnancies and have determined that the optimal first step cutoff for additional screening appears to be a blood sugar level equal to or greater than 135 mg/dL for women carrying twins.

The heart holds its own pool of immune cells capable of helping it heal after injury, according to new research. In a mouse model of heart failure, the researchers showed that blocking the bone marrow's macrophages from entering the heart protects the organ's beneficial pool of macrophages, allowing them to remain in the heart, where they promote regeneration and recovery. The findings may have implications for treating heart failure in humans.
