Astronomers have disproved the existence of two exoplanets thought to orbit Gliese 581 in ...

Those packing their bags for a trip to the two potentially habitable exoplanets previously claimed to be orbiting the red dwarf star Gliese 581 had better rethink their travel plans. Astronomers at Pennsylvania State University say the planets, Gliese 581 d and Gliese 581 g, don't actually exist.  Read More

KIST researchers have developed a material that has properties similar to graphene but is ...

For all the attention graphene gets thanks to its impressive list of properties, how many of us have actually encountered it in anything other than its raw graphite form? Show of hands. No-one? That's because it is still difficult to mass-produce without introducing defects. Now a team at the Korea Institute of Science and Technology (KIST) has developed a graphene substitute from plastic that offers the benefits of graphene for use in solar cells and semiconductor chips, but is easy to mass-produce.  Read More

Researchers have increased the toughness of various metals by giving them a 'gradient stru...

Steel is a common benchmark against which the strength of materials is measured, with "stronger than steel" a familiar catch cry for those touting the properties of some new space-age material. But now researchers at North Carolina State University have created steel that is stronger than steel using a process that increases the toughness of various metals by altering the microstructures within them.  Read More

Researchers at Princeton University have converted CO2 into formic acid by using an electr...

Rising atmospheric CO2 levels can generally be tackled in three ways: developing alternative energy sources with lower emissions; carbon capture and storage (CCS); and capturing carbon and repurposing it. Researchers at Princeton University are claiming to have developed a technique that ticks two of these three boxes by using solar power to convert CO2 into formic acid.  Read More

The Refuel is a smart tank gauge designed to ensure your tank is ready when you need it The partnership between Quirky and GE continues to bear fruit following the release of various smart products designed to work in conjunction with the Wink app. Joining the family is Refuel, a smart propane gas gauge designed to ensure your barbeque guests aren't dished up a plate of salad and raw meat after your grill runs out of gas.  Read More

Dr Jon Major says magnesium chloride could replace toxic cadmium chloride in CdTe solar ce...

Tofu has long been touted as a good way to clean out your insides, but now a researcher at the University of Liverpool says an ingredient in tofu could also be used to clean up solar cells. The hope is that the naturally occurring substance could replace a key ingredient in thin film solar cells that is highly toxic and expensive to produce.  Read More

The ReWalk motorized exoskeleton, which has been available in the UK since 2012, has now b...

Following multiple clinical studies, the Food and Drug Administration (FDA) has cleared the way for the ReWalk to be sold for personal use in the US. This makes the ReWalk the first motorized exoskeleton designed for people with lower body paralysis due to spinal cord injury to be cleared for personal use in the US.  Read More

Artist's concept of a derelict satellite being reeled in after being harpooned by the e.De...

In 2021, as part of its Clean Space Initiative, ESA plans to launch the e.DeOrbit mission. The aim of this mission is to clean up the important polar orbits between altitudes of 800 to 1,000 km (500 to 625 mil) that face the prospect of becoming unusable due to the increasing buildup of space debris. The ESA has now announced plans to examine the potential for the mission to use space harpoons to capture large items, such as derelict satellites and the upper stages of rockets.  Read More

The Nokia X2 is the first Android-based smartphone for Microsoft after taking over Nokia's...

Microsoft has unveiled its first Nokia-branded Android-based smartphone since the takeover of Nokia's Devices & Services business was finalized earlier this year. Aimed at the budget end of the smartphone market, the Nokia X2 packs a 4.3-inch WVGA display and is powered by a Snapdragon 200 dual core CPU clocked at 1.2 GHz and 1 GB of RAM.  Read More

The underside of the reinforced concrete beam has been fitted with two iron-based SMA stri...

Shape memory alloys (SMAs), which when heated are able to return to their original shape after being severely deformed, have found their way into everything from spectacle frames to cars. Now researchers at Empa in Switzerland have developed a new type of SMA that could allow the material to find applications in the building and construction industries.  Read More
