NASA officials have described the event as a “catastrophic anomaly” but have not pointed to a cause of explosion yet. NASA reports that the team did not experience any warning signs prior to launch that there would be a problem.

The Cygnus spacecraft atop the rocket was carrying 2290 kg (5050 lbs) of cargo for the International Space Station, including the Arkyd-3 satellite.

Scientists have opened the blood-brain barrier for the first time

The blood-brain barrier is a network of cells that separates the brain from the rest of the body, preventing harmful toxins and chemicals in the blood stream from entering the brain tissue. This blocking mechanism makes it very difficult to deliver drugs to the brain for the treatment of neurodegenerative disorders and cancer.

Fiber optics in Antarctica will monitor ice sheet melting

Earth is rapidly being wired with fiber-optic cables—inexpensive, flexible strands of silicon dioxide that have revolutionized telecommunications. They’ve already crisscrossed the planet’s oceans, linking every continent but one: Antarctica. Now, fiber optics has arrived at the continent, but to measure ice sheet temperatures rather than carry telecommunication signals. A team of scientists using an innovative fiber-optic cable–based technology has measured temperature changes within and below the ice over 14 months. This technology, they say, offers a powerful new tool to observe and quantify melting at the base of the West Antarctic Ice Sheet, the collapse of which may help drive a worldwide increase in sea levels of more than 3 meters.
