Honeywell Quantum Solutions has demonstrated record-breaking high fidelity quantum operations on their trapped-ion qubits. It is a major step towards producing the world’s most powerful quantum computer. Honeywell targets an operational trapped ion quantum computer by the end of 2019.

Currently the leading trapped ion quantum computer is by the startup IonQ. There are commercial quantum annealing systems from D-Wave Systems with 2000 qubits. There are superconducting quantum computers with 16–72 qubits from Google, IBM, Intel and Rigetti Systems.

For a robot to be able to “learn” sign language, it is necessary to combine different areas of engineering such as artificial intelligence, neural networks and artificial vision, as well as underactuated robotic hands. “One of the main new developments of this research is that we united two major areas of Robotics: complex systems (such as robotic hands) and social interaction and communication,” explains Juan Víctores, one of the researchers from the Robotics Lab in the Department of Systems Engineering and Automation of the UC3M.

The first thing the scientists did as part of their research was to indicate, through a simulation, the specific position of each phalanx in order to depict particular signs from Spanish Sign Language. They then attempted to reproduce this position with the robotic hand, trying to make the movements similar to those a human hand could make. “The objective is for them to be similar and, above all, natural. Various types of neural networks were tested to model this adaptation, and this allowed us to choose the one that could perform the gestures in a way that is comprehensible to people who communicate with sign language,” the researchers explain.

Finally, the scientists verified that the system worked by interacting with potential end-users. “The deaf people who have been in contact with the robot have reported 80 percent satisfaction, so the response has been very positive,” says another of the researchers from the Robotics Lab, Jennifer J. Gago. The experiments were carried out with TEO (Task Environment Operator), a humanoid robot for home use developed in the Robotics Lab of the UC3M.

They think gene-editing is a risk worth taking — if it means their babies will be able to hear.

A vegetable-picking robot that uses machine learning to identify and harvest a commonplace, but challenging, agricultural crop has been developed by engineers.

The ‘Vegebot’, developed by a team at the University of Cambridge, was initially trained to recognise and harvest iceberg lettuce in a lab setting. It has now been successfully tested in a variety of field conditions in cooperation with G’s Growers, a local fruit and vegetable co-operative.

Efficiently moving water upward against gravity is a major feat of human engineering, yet one that trees have mastered for hundreds of millions of years. In a new study, researchers have designed a tree-inspired water transport system that uses capillary forces to drive dirty water upward through a hierarchically structured aerogel, where it can then be converted into steam by solar energy to produce fresh, clean water.

The researchers, led by Aiping Liu at Zhejiang Sci-Tech University and Hao Bai at Zhejiang University, have published a paper on the new water transport and solar steam generation method in a recent issue of ACS Nano. In the future, efficient water transport methods have potential applications in water purification and desalination.

“Our preparation method is universal and can be industrialized,” Liu told Phys.org. “Our materials have excellent properties and good stability, and can be reused many times. This provides the possibility for large-scale desalination and sewage treatment in the future.”

Beryllium, a hard, silvery metal long used in X-ray machines and spacecraft, is finding a new role in the quest to bring the power that drives the sun and stars to Earth. Beryllium is one of the two main materials used for the wall in ITER, a multinational fusion facility under construction in France to demonstrate the practicality of fusion power. Now, physicists from the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics have concluded that injecting tiny beryllium pellets into ITER could help stabilize the plasma that fuels fusion reactions.

Experiments and computer simulations found that the injected granules help create conditions in the plasma that could trigger small eruptions called edge-localized modes (ELMs). If triggered frequently enough, the tiny ELMs prevent giant eruptions that could halt fusion reactions and damage the ITER facility.

Scientists around the world are seeking to replicate fusion on Earth for a virtually inexhaustible supply of power to generate electricity. The process involves plasma, a very hot soup of free-floating electrons and atomic nuclei, or ions. The merging of the nuclei releases a tremendous amount of energy.

We know that the rule “nothing lasts forever” holds true for everything. But the world of quantum particles doesn’t always seem to follow the rules.

In the latest findings, scientists have observed that quasiparticles in quantum systems could be virtually immortal. These particles can regenerate themselves after they have decayed — and this can have a significant impact on the future of quantum computing and humanity itself.

What’s not to like about this concept: high-efficiency solar cells gifting electric cars with mileage.

Bertel Schmitt, The Drive, said, “The solar roof could morph from mostly a marketing-device to a helpful feature.” He noted that, referring to plug-ins, “On a fair-weather day, the juice would be provided by the sun, a big improvement especially for people who don’t have their own garage.”

Toyota has ambitions over the concept and is to start testing an onboard solar recharging system where the hood, the roof, and back are covered with cells. The solar roof can charge while the car is on the move.

Taser bullets aren’t exactly a new concept—a bullet that zaps you with an electric jolt like a Taser.

That’s what the U.S. Marine Corps wants as a non-lethal munition that can be fired from a regular small arm. The U.S. military has been trying to develop a Taser-like bullet for 12 years but has yet to succeed. This time, the Marines hope to get it right.

The U.S. military already uses regular X-26 Tasers, pistol-like devices that fire two wired electrode darts that transmit a jolt to incapacitate a target. But not surprising for a device designed for civilian police forces, the wires limit an accurate shot to less than 25 feet, and the target is disabled for only about 5 seconds.
