SpaceX booster explodes in test flight

SpaceX gave a dramatic demonstration on Friday of why spacecraft undergo such thorough testing. At its testing ground at McGregor, Texas, a SpaceX Falcon 9 Reusable Development Vehicle 1 (F9R Dev 1) exploded in midair during a test flight. Nearby residents saw the fireball and local television station KXXV caught the incident on video. Elon Musk tweeted that the vehicle "auto-terminated," but there were no injuries or near-injuries, and that “Rockets are tricky …” .. Continue Reading SpaceX booster explodes in test flight

Largest ship ever built for the Royal Australian Navy begins final sea trials

The largest ship ever built for the Royal Australian Navy (RAN) has taken to sea as it begins its final contractor trials. The 27,800 tonne (30,600 ton) Nuship Canberra is the first of two Land Helicopter Dock (LHD) ships under construction for the Australian Defence Force and is billed by the RAN as “one of the most capable and sophisticated air–land-sea amphibious deployment systems in the world.” ..

Whooshh Innovations' "fish gun" shoots salmon over obstacles small and tall

If you live in an area where salmon spawn, then summer treats you to a free nature drama as the fish battle against currents, fight through rapids, struggle up tiny streams, and leap up waterfalls to return to the calm pools where they were born. Unfortunately, however intrepid the odd salmon is, they weren't built to take on a 300-ft tall hydroelectric dam. That's why Whooshh Innovations has developed a system that sucks the fish up through a plastic tube and shoots them over obstacles low and tall like so many piscatorial projectiles. ..

DARPA seeks high-tech alternatives to armor

As a quick visit to any armored division will make obvious, tanks are big ... really big. A Challenger 2 main battle tank, for example, weighs 62.5 tonnes (68.9 tons) and costs about £4.2 million (US$7 million). And as anti-tank weapons get better, tanks can only get bigger. To avoid armies of tomorrow having to pay for land-going battleships, DARPA’s Ground X-Vehicle Technology (GXV-T) program aims at developing lighter, more agile successors to the tank that protect themselves with more than ever-thicker walls of steel...

ExoLance project wants to use tunneling darts to hunt for life on Mars

If there’s life on Mars, it will have a great impact on Earth. But to answer the question, a group of engineers want to make an impact on Mars. Explore Mars, Inc., a private organization made up technologists and former NASA engineers, wants to look for signs of any present life on Mars not by scratching about on the surface, but by dropping supersonic lances on the planet that will penetrate deep into the Martian soil to seek out protected, potentially wet strata where life might still exist...

X-47B learns to share the deck with manned aircraft

Anyone who’s seen an aircraft carrier in full operation knows that everything needs to be carried out with absolute precision by a small army of sailors as one plane lands and is hurried aside to make room for the next. To show that its X-47B Unmanned Combat Unmanned Aerial Vehicle (UCAV) can work in this hectic environment alongside manned ones, the US Navy sent it to carry out landing and deck maneuvers aboard the aircraft carrier USS Theodore Roosevelt (CVN 71) in concert with an F/A-18 fighter...

MIT researchers propose recycling lead from old batteries to produce new solar cells

The world of modern technology is one of out with the old, in with the new. For battery technology, that means the expected demise of lead-acid batteries and replacement by a more efficient, cheaper, and environmentally-friendly alternative. This is good news, but leaves the problem of what to do with all the lead in the batteries currently in use when the time comes to dispose of them? Researchers at MIT have an answer – use it to make solar cells... Continue Reading MIT researchers propose recycling lead from old batteries to produce new solar cells

Creation of functional 3D brain-like tissue could aid in study of the brain

One approach to studying the brain rather than working on the whole thing at once is to examine small bits of it. With that in mind, researchers at the Tissue Engineering Resource Center at Tufts University, Boston have developed a three-dimensional brain-like tissue that is structurally similar to living rat brain tissue, functions enough like it for experimental purposes, and one that scientists have been able to keep alive for up to two months...
