Governments and leading computing companies such as Microsoft, IBM, and Google are trying to develop what are called quantum computers because using the weirdness of quantum mechanics to represent data should unlock immense data-crunching powers. Computing giants believe quantum computers could make their artificial-intelligence software much more powerful and unlock scientific leaps in areas like materials science. NASA hopes quantum computers could help schedule rocket launches and simulate future missions and spacecraft. “It is a truly disruptive technology that could change how we do everything,” said Deepak Biswas, director of exploration technology at NASA’s Ames Research Center in Mountain View, California.

Biswas spoke at a media briefing at the research center about the agency’s work with Google on a machine they bought in 2013 from Canadian startup D-Wave systems, which is marketed as “the world’s first commercial quantum computer.” The computer is installed at NASA’s Ames Research Center in Mountain View, California, and operates on data using a superconducting chip called a quantum annealer. A quantum annealer is hard-coded with an algorithm suited to what are called “optimization problems,” which are common in machine-learning and artificial-intelligence software.

However, D-Wave’s chips are controversial among quantum physicists. Researchers inside and outside the company have been unable to conclusively prove that the devices can tap into quantum physics to beat out conventional computers.

At MIT, researchers have developed a stretchable bandage-like device capable of sensing skin temperature, delivering drugs transdermally, and containing electronics that include LED lights for displaying information. The various components of the system are designed to work together, for example the drug dispenser activating only when skin temperature is within a certain range and the LEDs lighting up when the drug reservoirs are running low. While this is only a prototype device, it certainly points toward future flexible devices that stay attached to a person’s skin, or even internally, for extended periods of time while providing health data and taking therapeutic actions in an intelligent way.

The device is based on a stretchable hydrogel matrix that reliably holds onto embedded metallic components linked by pliable wires. The hydrogel was made to have a stiffness similar to human soft tissues so that it blends well with the body when attached to it. When wires, drug reservoirs, delivery channels, and electronic components were built-in, the team tested the stretchiness of the final result showing that it maintains functionality even after repeated stress.

Flashing some interplanetary gold bling and sipping “space water” might sound far-fetched, but both could soon be reality, thanks to a new US law that legalizes cosmic mining.

In a first, President Barack Obama signed legislation at the end of November that allows commercial extraction of minerals and other materials, including water, from asteroids and the moon.

That could kick off an extraterrestrial gold rush, backed by a private aeronautics industry that is growing quickly and cutting the price of commercial space flight.

In a breakthrough that could lead to printable organs and an enhanced understanding of human physiology, researchers from Lawrence Livermore National Labs have 3D-printed functional blood vessels that look and function like the real thing.

3D bioprinters are similar to conventional 3D printers, but instead of using inert materials, they use “bio-ink:” basic structural building blocks that are compatible with the human body.

Researchers at Linköping University’s Laboratory of Organic Electronics, Sweden, have developed power paper — a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer. The results have been published in Advanced Science.

One sheet, 15 centimetres in diameter and a few tenths of a millimetre thick can store as much as 1 F, which is similar to the supercapacitors currently on the market. The material can be recharged hundreds of times and each charge only takes a few seconds.

It’s a dream product in a world where the increased use of renewable energy requires new methods for energy storage — from summer to winter, from a windy day to a calm one, from a sunny day to one with heavy cloud cover.

An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors. Their downside? The films are notoriously riddled with defects, killing their performance.
