With industry momentum mounting around a low power Wi-Fi solution, Wi-Fi Alliance announced the Wi-Fi HaLow designation for products incorporating IEEE 802.11ah technology. Wi-Fi HaLow operates in frequency bands below one gigahertz, offering longer range, lower power connectivity to Wi-Fi CERTIFIED products. Wi-Fi HaLow will enable a variety of new power-efficient use cases in the

The first durable, flexible cloth that harnesses human motion to generate energy From light-up shoes to smart watches, wearable electronics are gaining traction among consumers, but these gadgets’ versatility is still held back by the stiff, short-lived batteries that are required. These limitations, however, could soon be overcome. In the journal ACS Nano, scientists report

The discovery could significantly reduce the risk of deadly hospital-acquired infections and revolutionise the way the medical industry deals with infection control. Secondary infections are a serious and potentially deadly complication for hospital patients. Antibacterial fabrics do not allow nasty disease-causing bacteria to stick to and grow on their surface – creating an infection free

A team of international scientists have created a new form of highly-efficient, low-cost insulation based on the wings of a dragonfly. The material, known as an aerogel, is the most porous material known to man and ultralight, with a piece the size of a family car weighing less than a kilogram. Starting out as a wet

The internet has become a critical means of communication during humanitarian crises and a crucial everyday tool for people around the world. Now, a Portuguese company wants to make sure everyone has access to it. Quarkson plans to use unmanned aerial vehicles (UAVs) to transmit internet access “to every corner of the world.” Quarkson’s SkyOrbiter

New system extends the lives of flying microrobots Call them the RoboBats. In a recent article in Science, Harvard roboticists demonstrate that their flying microrobots, nicknamed the RoboBees, can now perch during flight to save energy – like bats, birds or butterflies. “Many applications for small drones require them to stay in the air for

Using a process described as “a lint roller in reverse,” engineers from the University of California, Berkeley, have created a pressure-sensitive electronic artificial skin from semiconductor nanowires. This “e-skin,” as it’s called, could one day be used to allow robots to perform tasks that require both grip and a delicate touch, or to provide a

A unique new instrument at Gemini South in Chile takes the removal of atmospheric distortions (using adaptive optics technology) to a new level. Today’s release of seven ultrasharp, large-field images from the instrument’s first science observations demonstrate its remarkable discovery potential. Astronomers recently got their hands on Gemini Observatory’s revolutionary new adaptive optics system, called

Looking at human beings as ecosystems that contain many collaborating and competing species could change the practice of medicine If the microbiome does turn out to be as important as current research is hinting, then a whole new approach to treatment beckons. WHAT’S a man? Or, indeed, a woman? Biologically, the answer might seem obvious.
