Darren's love of technology started in primary school with a Nintendo Game & Watch Donkey Kong (still functioning) and a Commodore VIC 20 computer (not still functioning). In high school he upgraded to a 286 PC, and he's been following Moore's law ever since. This love of technology continued through a number of university courses and crappy jobs until 2008, when his interests found a home at Gizmag.
The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame.
After unveiling the world's first flexible OLED TV
at CES earlier this year, LG has gone a step further with the unveiling of two new 18-inch OLED panels: the first is a transparent display, while the second can be rolled up. Although both fall short of the 77-inch flexible TV on show at CES, the company says the new panels prove that it has the technology to bring rollable TVs with screens in excess of 50 inches to market in the future.
Hydrogen fueled vehicles, such as Toyota's FCV
and Hyundai's Tuscon Fuel Cell
, face a chicken or egg predicament: consumers are rightfully hesitant to invest in such vehicles if they don't have a convenient way to refuel them, and energy companies don't want to cough up dollars for costly infrastructure without significant numbers of such vehicles on the road. But a study by researchers at Sandia National Laboratories says that more existing gas stations in California could readily integrate hydrogen fuel than previously thought.
Conventional lithium-ion batteries rely on anodes made of graphite, but it is widely believed that the performance of this material has reached its zenith, prompting researchers to look at possible replacements. Much of the focus has been on nanoscale silicon
, but it remains difficult to produce in large quantities and usually degrades quickly
. Researchers at the University of California, Riverside have overcome these problems by developing a lithium-ion battery anode using sand.
The flood of smart devices aimed at hooking into the Internet of Things (IoT) seems to be turning into a flood of consortia of industry heavyweights looking to standardize the IoT. First we had the AllSeen Alliance
, which was followed by the Industrial Internet Consortium
(IIC) and now we have the Open Interconnect Consortium (OIC), which boasts Atmel, Dell, Broadcom, Intel, Samsung and Wind River as members.
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.
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.
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.
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.
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.
