Scientists have now made metamaterials scalable in their purpose and usage.

Metamaterials — materials whose function is determined by structure, not composition — have been designed to bend light and sound, transform from soft to stiff, and even dampen seismic waves from earthquakes. But each of these functions requires a unique mechanical structure, making these materials great for specific tasks, but difficult to implement broadly.

But what if a material could contain within its structure, multiple functions and easily and autonomously switch between them?

Treatment for certain diabetes cases involves constant monitoring of blood-glucose levels and daily insulin shots. But scientists are now developing a painless “smart” patch that monitors blood glucose and releases insulin when levels climb too high. The report on the device, which has been tested on mice, appears in the journal ACS Nano.

People with Type 1 diabetes don’t make insulin—a hormone that regulates blood glucose, or sugar. Those with Type 2 diabetes can’t use insulin effectively. Either way, glucose builds up in the blood, which can lead to a host of health problems, including heart disease, stroke, blindness and amputation of toes, feet or legs. To avoid these outcomes, people with Type 1 or advanced Type 2 diabetes regularly prick their fingers to measure blood-sugar levels, and some patients must inject themselves with insulin when needed. But sometimes, despite a person’s vigilance, glucose levels can still get out of whack. Zhen Gu and colleagues wanted to come up with a simpler, more effective, shot-free way to manage diabetes.

The researchers developed a skin patch covered in painless microneedles that are loaded with tiny insulin-carrying pouches. The pouches are engineered to break apart rapidly and release the insulin in response to rising glucose levels. Diabetic mice wearing the patch maintained consistent concentrations of insulin in their blood. When these mice received a shot of glucose, their blood sugar levels spiked initially, but then fell to normal levels within two hours.

Never ceases to amaze me what DARPA is up to these days.

Drones are everywhere these days – from using them to take elaborate selfies to launching missiles at military targets, delivering aid to war torn areas to imaging the deadly environment around lava lakes, they appear to be the multipurpose tool of the moment. Perhaps slightly strangely, then, the Defense Advanced Research Projects Agency (DARPA) wants drones to vanish into thin air. Specifically, they want drones that are biodegradable, able to fade away after completing their mission.

Nice.

MINNEAPOLIS — Scanning a premature infant’s brain shortly after birth to map the location and volume of lesions, small areas of injury in the brain’s white matter, may help doctors better predict whether the baby will have disabilities later, according to a new study published in the January 18, 2017, online issue of Neurology ®, the medical journal of the American Academy of Neurology.

According to the Centers for Disease Control and Prevention, one in 10 babies is born prematurely in the United States.

Lack of oxygen to the brain is the most common form of brain injury in premature infants, resulting in damage to the white matter. White matter contains nerve fibers that maintain contact between various parts of the brain. Damage to white matter can interfere with communication in the brain and the signals it sends to other parts of the body.

QC communications (includes networking) is now available in China.

Nice job China; now if the rest of us can catch up.

China’s quantum communication satellite, launched last August, is officially operational after four months of in-orbit testing, the Chinese Academy of Sciences (CAS) said Wednesday.

Hope folks are realizing this is happening and now real. Not sure what experiments their doing as they have already been experimenting already on hacking.

The world’s first quantum science and communications satellite has been handed over to Chinese scientists for the official start of experiments to test the phenomena of quantum entanglement and ‘unhackable’ quantum communication.

The Quantum Experiments at Space Scale (QUESS) satellite was launched on August 15 last year and soon after began testing its payloads and space-to-ground links.
