The W88 ALT 370 warhead was dropped from a crane to simulate a loading accident

Dropping a nuclear warhead may not seem like a particularly bright idea, but earlier this year Sandia National Laboratories did just that. As part of the US government’s Life Extension Program (LEP) for its nuclear arsenal, the inert W88 ALT 370 warhead was dropped from a crane in New Mexico onto a slab of concrete to test the updated design’s safety.  Read More

Electron microscope scan of a THz circuit detailing its high-electron-mobility transistors

Getting into the Guinness Book of World Records isn't just about who can eat the most hotdogs or fly a paper airplane the highest. Sometimes it involves technological breakthroughs with huge potential. Guinness has handed DARPA’s Terahertz Electronics program the award for the fastest solid-state amplifier integrated circuit. Developed by Northrop Grumman, the Terahertz Monolithic Integrated Circuit (TMIC) is a ten-stage common-source amplifier that cranks speeds of one terahertz (1012 Hz), or one trillion cycles per second.  Read More

The accident occurred less than 20 seconds after lift off of the Antares rocket (Image: NA...

At a press conference arranged only a few hours after the event, NASA released details of the explosion of the Antares rocket carrying the unmanned Cygnus supply ship to the International Space Station (ISS). The space agency said that the launch pad at Wallops Island, Virginia, where the 240,000-kg (530,000-lb) rocket went up in flames seconds after lift off has been cordoned off by firefighters until daylight because of the on-going hazards from fires, and scattered solid and hypergolic fuel from the Antares.  Read More

The chemical computer works by differences in surface tension

If you’re going out for pizza in Budapest, which would you choose to get you there; a smartphone with GPS or a drop of gel on a little maze? A team of scientists from Switzerland, Hungary, Japan and Scotland under the leadership of Empa, the Swiss Federal Laboratories for Materials Science and Technology, thinks that the gel might be your better bet because that little bit of plastic and goo is a chemical computer capable of navigating a maze faster than a satnav.  Read More

The microwalkers consist of a pair of particles, one of which has magnetic properties and ...

Ever wonder how a germ knows where to attack the body or how a white blood cell knows where to counter attack? How bacteria find food? Or how cells organize themselves to close a wound? How can something so simple do things so complex? A team of MIT researchers is seeking the answers as they develop "microwalkers" – microscopic machines that can move unguided across the surface of a cell as they seek out particular areas.  Read More

Waste water from fracking is over five times saltier than seawater (Photo: Christopher Hal...

Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well.  Read More

The Yardarm Sensor fits into the grip of a firearm to monitor use in real time

Anytime a police officer draws their weapon, it's likely to be a tense, confusing situation where split second decisions can be the difference between life and death. In an attempt to reduce some of the confusion, Yardarm has developed a wireless sensor that allows firearms to be tracked and monitored in real time thanks to a small electronics package that fits into the weapon's grip.  Read More

The odor is based on chemicals outgassing from comet 67P/Churyumov–Gerasimenko (Image: ESA...

Comets may be deep-frozen fossils that could provide clues as to the earliest days of the Solar System, but what does one smell like? Not very nice, says ESA, whose Rosetta space probe has discovered that comet 67P/Churyumov–Gerasimenko (67P/C-G) has the aroma of rotten eggs and horse dung.  Read More

Artist's impression of the Krossblade SkyCruiser over London

Can’t decide if you want an airplane, a helicopter, or a flying car? Then why not all three at once? Arizona-based start-up Krossblade seems to think the same way with its SkyCruiser concept – an electric hybrid aircraft that not only switches between being an airplane and a quadcopter, but can be driven on the road as well.  Read More

The center of the exhibit is a giant radio tuner from the 1920s

If the 19th and 20th centuries were the Transportation Age, then the 21st century is the Information Age. Like most other ages, it didn't suddenly leap into being with the arrival of the Web or the smartphone – it has a history going back more than 200 years. The Science Museum in London is exploring this history in a new permanent exhibit called "Information Age: Six Networks That Changed Our World," which was recently opened by Queen Elizabeth II when she sent the first tweet by a British monarch.  Read More
