Cutting Edge

After multiple scrubbed launches last week, an Antares rocket finally lifted off the ground from NASA's Wallops Flight Facility in Virginia as part of Orbital Sciences' bid to transport cargo to the International Space Station.

The rocket lifted off at 5 p.m. ET Sunday and achieved orbit smoothly. It launched an 8,400-pound mock Cygnus supply ship into orbit about 158 miles above Earth.

Antares is a medium-class, two-stage, 13-storey rocket designed to carry payloads of up to 6,500 kg (14,329 pounds). Along with SpaceX, Orbital was awarded a Commercial Orbital Transportation Services (COTS) contract to … Read more

I just rewatched Ridley Scott's "Prometheus," and I think the soundtrack's opening horn melody would go perfectly with this NASA pic.

The Hubble Space Telescope has photographed the Horsehead Nebula in stunning detail. The nebula, about 1,500 light years away in the constellation of Orion, was imaged in infrared wavelengths against the backdrop of the Milky Way.

The pink cast is from hydrogen gas behind the nebula, which is being lit up by Sigma Orionis, a five-star system. … Read more

After weeks of testing, the Federal Aviation Administration announced on Friday that it has approved Boeing's plans to fix batteries on its 787 Dreamliner airplanes.

The FAA said it will start instructing operators next week about the changes that will keep the batteries from catching on fire. This will allow airlines to get the planes up and running again.

"A team of FAA certification specialists observed rigorous tests we required Boeing to perform and devoted weeks to reviewing detailed analysis of the design changes to reach this decision," FAA Administrator Michael Huerta said in a press release. … Read more

There are many gestural interfaces under development, but our fingers remain one of the most useful tools we have. Fujitsu's FingerLink lets your fingers control a scanner and projector for printed information, acting as a bridge between digital and analog tech.

The prototype uses off-the-shelf cameras and projectors. Fujitsu's image-processing software links the two.

It can accurately detect where your fingers are as you touch or swipe any printed matter, letting you copy text or images and project them elsewhere. The size of projected images can similarly be adjusted with a fingertip. … Read more

After three months of sitting on the ground, it's looking like Boeing's 787 Dreamliner jets may be able to soar again.

According to the Wall Street Journal, the Federal Aviation Administration is rumored to announce as soon as Friday that the jets will soon be allowed for takeoff. People familiar with the matter told the Journal that the FAA believes that Boeing has proven that the redesigned batteries are now safe.

Boeing's Dreamliners were grounded in January after a battery fire on an All Nippon Airways flight let to a forced evacuation of the plane. The FAA … Read more

A researcher who used to work in digital television has just led a team of Columbia University engineers to win the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge.

Dimitris Anastassiou, who is now a systems biologist (meaning he investigates interactions within biological systems), reports in the April 17 issue of Science Translational Medicine that his team's winning computation model is extremely predictive of breast cancer survival.

Before the challenge, Anastassiou and his team identified what they call "attractor metagenes," which are genetic signatures expressed in almost the exact same way across many types of cancer. Their new … Read more

NASA, that wily band of intergalactic peepers, says it's spied three distant planets in two different solar systems that are the proper distance from their suns to make them potentially habitable.

I can almost hear Elon Musk's pitch for time-shares in the Kepler-62 and Kepler-69 systems already.… Read more

One of the biggest bugbears of smartphones is just how much juice they drain -- and how long they take to recharge. Batteries are also the reason many devices can't be smaller; after all, the batteries have to fit somewhere (although, given the burgeoning phablet market, that's not exactly a huge problem).

Scientists have made several recent attempts to build a better lithium ion battery. In the latest push, a team of researchers led by mechanical science and engineering professor William P. King at the University of Illinois in Urbana-Champaign has developed a new type of lithium ion battery that's just a fraction of the size of the batteries we use now -- and that can out-power the best supercapacitors. … Read more

NASA's Kepler spacecraft has been in hot pursuit of extraterrestrial life for four years now. And, on Thursday, it's letting people know just what it's found lurking in the Milky Way.

NASA is holding a Kepler briefing at 11 a.m. PT on Thursday. It will be broadcast live on NASA Television and on UStream. The agency will also host a moderated Web chat with Kepler Deputy Project Scientist Nick Gautier of NASA's Jet Propulsion Lab. During the briefing, people can submit questions to the Kepler scientists via Twitter with the hashtag #AskNASA.

Kepler launched in … Read more
