Microscope photo of tungsten diselenide samples connected to electrodes

Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.  Read More

ESA's 15 m-diameter dish antenna at the European Space Astronomy Centre (ESAC), near Madri...

As you might expect, acquiring a signal from a satellite traveling at speeds of over 17,400 mph can be a tricky business. A new system called SARAS, which is a Spanish acronym for "Fast Acquisition of Satellites and Launchers," more than doubles the effective area of the receiving dish antenna, allowing the signal to be acquired much faster.  Read More

Fuel depots in space could help make future missions to the Moon more economical says an M...

Getting into space is an expensive business where every little bit of extra weight, which includes the fuel powering the spacecraft, can add thousands of dollars to the cost of a mission. A team of researchers at MIT proposes establishing gas stations in space as a possible way to help cut the cost of future missions to the Moon.  Read More

Since first taking to the air in June 2009, trials of the UK's homegrown Watchkeeper tactical unmanned aerial vehicle have been conducted by industry partners including QinetiQ. The UK Ministry of Defence has now announced the aircraft has been awarded a Release To Service, clearing the way for flight training to begin with the Royal Artillery.  Read More

DARPA's ARES consists of a VTOL flight module capable of carrying several different types ...

Helicopters are an invaluable military resource for transporting supplies, carrying out surveillance and reconnaissance, and evacuating casualties from rugged terrain. Unfortunately, they are also a finite resource. That's why DARPA is looking to share the load with the Aerial Reconfigurable Embedded System (ARES) concept, a compact, high-speed and highly-automated delivery system with vertical take-off and landing (VTOL) capabilities.  Read More

Ring's gesture recognition is precise enough to identify letters written in mid air

We've already seen rings that unlock doors and mobile devices, show the time, act as a mouse or display notifications from a connected mobile device, but, like the Fin, the Ring from California-based Logbar aims to take finger wagging to the next level. Featuring Bluetooth Low Energy (BLE) connectivity, the Ring is designed to allow control of mobile devices and home appliances, make electronic payments and even type text in mid air with a wave of a finger.  Read More

Nissan's e-NV200 borrow heavily from the Nissan LEAF

Nissan originally began testing of an all-electric version of its NV200 light commercial van back in mid-2010 before showcasing the e-NV200 concept at the North American International Auto Show in 2012. Now the automaker has unveiled the production version of the LEAF's bigger brother in Geneva, touting the vehicle as a practical and sustainable city delivery vehicle or people mover.  Read More

Samsung's Chromebook 2 Series will come in 11-6 (pictured) and 13.3-inch models

Samsung, which along with Acer was the first to market with Chrome OS-based Chromebooks in 2011, has announced the launch of its Chromebook 2 Series. The new machines boast faster startup times, longer battery life and an easy-to-grip lid featuring the faux leather stitched design found on the Galaxy Note 3.  Read More

The Global Precipitation Measurement (GPM) Core Observatory was launched last Thursday aboard a Japanese H-IIA rocket that blasted off from Tanegashima Space Center on Tanegashima Island in southern Japan. Weighing in at 4-ton, the GPM is the largest spacecraft ever built at NASA's Goddard Space Flight Center and will help provide a more detailed picture of the Earth's precipitation to assist climate scientists and help improve forecasting of extreme weather events.  Read More

Current gesture recognition technology seen in devices such as Samsung's Galaxy S4 generally rely on the device's camera. This not only creates a drain on the device's battery, but means users need to retrieve the phone from their pocket or handbag to make use of the technology. The new AllSee system developed at the University of Washington (UW) overcomes both these problems by using wireless signals not only as a power source, but also to detect user gestures when the phone is tucked away out of sight.  Read More
