Nearly 1,000 times thinner than a human hair, nanowires can only be understood with quantum mechanics. Using quantum models, physicists from Michigan Technological University have figured out what drives the efficiency of a silicon-germanium (Si-Ge) core-shell nanowire transistor.

Core-Shell Nanowires

The study, published last week in Nano Letters, focuses on the quantum tunneling in a core-shell nanowire structure. Ranjit Pati, a professor of physics at Michigan Tech, led the work along with his graduate students Kamal Dhungana and Meghnath Jaishi.

Artificial intelligence (AI) technologies offer great promise for creating new and innovative products, growing the economy, and advancing national priorities in areas such as education, mental and physical health, addressing climate change, and more. Like any transformative technology, however, AI carries risks and presents complex policy challenges along a number of different fronts. The Office of Science and Technology Policy (OSTP) is interested in developing a view of AI across all sectors for the purpose of recommending directions for research and determining challenges and opportunities in this field. The views of the American people, including stakeholders such as consumers, academic and industry researchers, private companies, and charitable foundations, are important to inform an understanding of current and future needs for AI in diverse fields. The purpose of this RFI is to solicit feedback on overarching questions in AI, including AI research and the tools, technologies, and training that are needed to answer these questions.

Was our universe born from the one before it? Neil Turok and Steffen Gielen explore the “big bounce” in the latest edition of Physical Review Letters.

In just a few years, we could see an electric car on the market that doesn’t need a charging station to ‘fuel up.’

The biggest apparent stumbling blocks for electric vehicles (EVs) seems to be their range — the distance that can be driven between charging — and the time it takes for an EV battery to be charged. When competing against gas cars, which can be filled up in just a few minutes, and can cover a range of several hundred miles per tank, the idea of having a limited range and a longer ‘fueling’ time with an EV isn’t one that most of us are comfortable with. And when considering the easy availability of fuel from the vast number of gas stations (as opposed to the EV charging stations that are few and far between in most areas), switching from gas to electric mobility is a bit of a stretch for many people (not even taking into account the higher cost for EVs).

However, as costs go down, and as EV ranges increase (along with the growing numbers of dedicated EV charging stations), electric transport options will start to become more and more desirable (especially in times of rising gas prices), but will still most likely need to be tethered to charging points, unless the next generation of electric cars follows in the footsteps of one Chinese company.

Data from a now-defunct X-ray satellite is providing new insights into the complex tug-of-war between galaxies, the hot plasma that surrounds them, and the giant black holes that lurk in their centres.

Launched from Japan on February 17, 2016, the Japanese space agency (JAXA) Hitomi X-ray Observatory functioned for just over a month before contact was lost and the craft disintegrated. But the data obtained during those few weeks was enough to paint a startling new picture of the dynamic forces at work within galaxies.

New research, published in the journal Nature today, reveals data that shows just how important the giant black holes in galactic centres are to the evolution of the galaxies as a whole.

Scientists at the Computational Story Laboratory have identified the six emotional arcs that form the building blocks of all stories.

Space and technology have collided in a recent design challenge hosted by Star Trek and NASA. Future Engineers has once again called upon students to push their creative boundaries. Since February 2016, they have been working hard to engineer 3D printable design concepts aimed at food sustainability in space. More than 400 students from 30 US states created amazing solutions that would aid astronauts in harvesting, preparing, eating and disposing of food while on long-duration space missions. A panel of judges from NASA, the American Society of Mechanical Engineers (ASME) Foundation, and Made In Space, Inc. selected Kyle Corrette from Phoenix, Arizona and Sreyash Sola from Asburn, Virginia as winners of their respective Teen Group and Junior Group. Judges also selected three finalists from each group, who were each awarded a MakerBot Replicator Mini Compact 3D printer for their school and a PancakeBot for their household. Winners Corrette and Sola received a grand prize trip to New York City for a private viewing of the Space Shuttle Enterprise with astronaut Mike Massimino at the Intrepid Sea, Air and Space Museum, as well as a VIP tour of MakerBot’s headquarters in Brooklyn, New York.

BAE systems and a professor at Glasgow University have revealed a way to really grow drones with an advanced form of chemical 3D printing.

The news has already swept the mainstream news sites, even though this is little more than a theoretical exercise right now. Professor Lee Cronin, the man behind the concept, freely admits that he has a mountain to climb to turn this dream into a reality.

The video, then, which depicts a pair of printer heads laying the absolute basics in a vat before the drone literally grows from almost nothing, is really a pipe dream right now.
