Alongside developing a quantum computer, one group of scientists is selling its components to other researchers.

A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter. The research appeared in the journal Advanced Materials.

“This is very exciting,” says Xiaomeng Liu, a graduate student in electrical and computer engineering in UMass Amherst’s College of Engineering and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

“The air contains an enormous amount of electricity,” says Jun Yao, assistant professor of electrical and computer engineering in the College of Engineering at UMass Amherst, and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt—but we don’t know how to reliably capture electricity from lightning. What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

Human-computer interaction company Sightful is releasing its first product, Spacetop, a screen-less “augmented reality laptop” projecting tabs across a 100-inch virtual screen. The laptop — if you can call it that — is a hardware deck and full-size keyboard with a pair of tailored NReal glasses. The glasses project tabs directly in front of whatever the user is looking at while remaining invisible to anyone else.

Specs-wise, Spacetop is running a Snapdragon 865 paired with an Adreno 650 GPU, 8GB RAM and 256GB storage, putting it in the same class as some of the smartphones that are already capable of driving AR glasses. It’s not smartphone-sized, however, measuring 1.57-inches high, 10.47-inches wide and 8.8-inches deep, and it weighs in at 3.3 pounds, the same as plenty of laptops we could choose to mention here.

Sightful is clearly gunning for a crossover hit in the work-from-home-or-anywhere market. “Laptops are the centerpiece of our daily working lives, but the technology has not evolved with the modern, work from anywhere, privacy matters, ‘road warrior’ mentality. Meanwhile, augmented reality is full of potential and promise but is yet to find its daily use case,” said Tamir Berliner, Sightful co-founder who previously worked at both Leap Motion and Primesense. “We are at the perfect moment for a significant paradigm shift in a device we all know and love.”

The first protein-based nano-computing agent that functions as a circuit has been created by Penn State researchers. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.

Traditional synthetic biology approaches for cell-based therapies, such as ones that destroy cancer cells or encourage tissue regeneration after injury, rely on the expression or suppression of proteins that produce a desired action within a cell. This approach can take time (for proteins to be expressed and degrade) and cost cellular energy in the process. A team of Penn State College of Medicine and Huck Institutes of the Life Sciences researchers are taking a different approach.

“We’re engineering proteins that directly produce a desired action,” said Nikolay Dokholyan, G. Thomas Passananti Professor and vice chair for research in the Department of Pharmacology. “Our protein-based devices or nano-computing agents respond directly to stimuli (inputs) and then produce a desired action (outputs).”

Finding the best quantum computing stocks to buy is critical because this is clearly the next big industry.

Quantum computers promise to bring the power of quantum mechanics to bear in solving our most vexing problems. They may be capable of processing more data, faster, than any classical computer.

If all that happens, then quantum computing stocks may bring generational wealth to their investors.

A fluxonium qubit can keep its most useful quantum properties for about 1.48 milliseconds, drastically longer than similar qubits currently favoured by the quantum computing industry.

Even the scientists who have made quantum computers their life’s work say they can’t do anything useful yet — but the future is bright. Plus, how China’s data privacy laws affects researchers and LIGO is back, better than ever.

Researchers have experimentally demonstrated a new quantum information storage protocol that can be used to create Greenberger-Horne-Zeilinger (GHZ) quantum states. There is a great deal of interest in these complex entangled states because of their potential use in quantum sensing and quantum error correction applications.

Chun-Ju Wu from the California Institute of Technology will present this research at the Optica Quantum 2.0 Conference and Exhibition, as a hybrid event June 18–22 in Denver, Colorado.

Quantum-based technologies store information in the form of qubits, the quantum equivalent of the binary bits used in classical computing. GHZ states take this a step further by entangling three or more qubits. This increased complexity can be used to store more information, thus boosting precision and performance in applications such as quantum sensing and networking.
