The TOSA buses charge as they stand at a bus stop

It’s one thing to invent an electric bus, a hydrogen car, or other green transportation technology, but quite another for it to work in the real world. For example, the Trolleybus Optimisation Système Alimentation (TOSA) flash-charging electric bus system may be the most brilliant idea ever, but if it can’t stay in the black, then might as well be drawn by diesel-powered horses. Scientists at the École Polytechnique Fédérale de Lausanne (EPFL) are hoping to avoid that scenario by developing a computer model that helps engineers integrate the buses into existing transport systems while keeping costs down.  Read More

LLNL researchers are working to improve 3D metal printing using higher-powered lasers

To paraphrase Samuel Johnson, there was a time when 3D metal printing was like a dog walking on his hind legs – it wasn't done well; but you were surprised to find it done at all. Now that laser sintering or Selective Laser Melting (SLM) is used for everything from printing rocket engine components to semi-automatic pistols, the time for surprise may b long past, but the technology still has plenty of room for improvement. That's why researchers at the Lawrence Livermore National Laboratory (LLNL) are working on simulations to improve the speed of 3D laser printing and the quality of the final product by using higher-powered lasers.  Read More

The ISSpresso is designed to work in the zero gravity of the International Space Station

Living on the International Space Station (ISS) has its drawbacks. For one thing, the morning coffee run to the local espresso shack is the definition of impractical. To make sure that astronauts are suitably caffeinated, Italian coffee company Lavazza is developing the ISSpresso; the first espresso machine built to meet the needs of astronauts who need a decent jolt before facing the day.  Read More

Once you've sent the first space probe to Pluto, what do you do for an encore? As NASA’s New Horizons spacecraft races to its encounter with the dwarf planet next year, the Hubble Space Telescope Time Allocation Committee have given its recommendation that the Hubble be used to find the Horizons’ next destination in the outer reaches of the Solar System.  Read More

The Concept 2020 Vision Gran Turismo is Nissan's glimpse at the supercar of the future

“Cor, I’d like to take that for a spin.” It's what most of us think when looking at concept cars, but the chances of that ever happening are usually less than slim. The Nissan Concept 2020 Vision Gran Turismo is an exception to the rule – at least, it's a virtual exception. That’s because next month, the just revealed supercar concept becomes available for download for Polyphony Digital’s Gran Turismo 6 video game for the Playstation console.  Read More

NASA astronaut Rick Mastracchio prepares to test the ultraviolet light decontamination har...

The International Space Station (ISS) is perhaps the most artificial environment that human beings have ever taken up residence in. It’s not the sort of place where you’d want a lab accident, because you can’t run out the door and wait in the carpark for the air to clear, so NASA uses gloveboxes to keep the crew and equipment separate from dangerous contaminants. To increase this level of safety and expand the number experiments the station can carry out, the space agency is fitting one of the larger gloveboxes with an Ultraviolet Germicidal Irradiation (UVGI) system to to prevent potentially dangerous microorganisms from escaping.  Read More

WindTracer will drop out of aircraft to evaluate atmospheric conditions for accurate air d...

For a besieged soldier or a disaster victim, a plane dropping supplies is the most welcome sight in the world – unless the drop ends up drifting off out of reach. To help make sure that airdrops end up where they belong, the US Air Force Research Laboratory has awarded a contract to Lockheed Martin to adapt its WindTracer wind measurement system for a Precision Air Drop system to help aircrews land supplies faster and on target.  Read More

The US Navy is deploying its first laser weapon on the USS Ponce in a few months. The technology also has obvious potential for ground vehicles – a fact that hasn't escaped the US Marine Corps. The Office of Naval Research has awarded contracts to develop a similar laser weapon that can be installed in light-tactical vehicles instead of ships as part of its Ground-Based Air Defense Directed Energy On-the-Move (GBAD) program.  Read More

Rod photoreceptors (in green) within a 'mini retina' derived from human iPS cells in the l...

The eye is often compared to a camera, but although its basic design is as simple as an old-fashioned box Brownie, its detailed structure is more complex than the most advanced electronics. This means that, unlike simpler organs, studies of retinal disease rely heavily on animal studies, and treating such illnesses is extremely difficult. One ray of hope in the field comes from researchers at Johns Hopkins, who have constructed a functioning segment of a human retina out of stem cells that is able to respond to light.  Read More

Artist Mark Rademaker has unveiled a set of concept images imagining what a spaceship capable of traveling to other stars in a matter of months would really look like. Although it may look like something from the next science fiction epic and is unlikely to lift off anytime soon, his IXS Enterprise design is actually based on some hard science.  Read More
