Australian physicists’ team has developed a new research assistant to carry out experiments in quantum mechanics in an artificial intelligence (AI) algorithm form, which quickly took control of the experiment, learned the job tasks and even innovated. In a statement, co-lead researcher Paul Wigley from the Australian National University (ANU) Research School of Physics and Engineering, said he didn’t expect that the machine would be able to conduct the experiment itself from scratch within an hour.

He added that in case a simple computer program had been used, it would have taken much more time than the age of the universe to go through all the combinations and work on it.

Scientists were looking forward to reconstruct an experiment that was awarded the 2001 Nobel Prize in Physics, which included very cold gas trapped in a laser beam called a Bose-Einstein condensate.

US Navy paying D-Wave to train them on QC.

A division of the U.S. Navy intends to pay Canadian company D-Wave $11 million to learn how to use its quantum computing infrastructure, according to a federal filing posted online on Monday.

The unit seeking this training is the Navy’s Space and Naval Warfare Systems Center Pacific, known as SPAWAR or SSC-PAC for short, which is headquartered in San Diego and has previously researched amphibious throwable robots, unmanned aerial vehicles, virtual reality, and many other technologies. The filing does not actually cover the cost of quantum computing hardware. But NASA has been allowing SPAWAR scientists to learn how to use the D-Wave machine that it operates with Google at the NASA Ames Research Center, the San Diego Union-Tribune reported last month.

Quantum computers employ quantum bits, or qubits, each of which can be zero or one or both, unlike the regular bits in classical computers. The superposition of qubits lets machines perform great numbers of computations at once, making a quantum computer highly desirable for certain types of processes. Google recently found that quantum annealing with D-Wave hardware is 100 times faster than simulated annealing on a classic computer chip.

New and improve fuel cells.

Fuel cells, which generate electricity from chemical reactions without harmful emissions, have the potential to power everything from cars to portable electronics, and could be cleaner and more efficient than combustion engines.

(Phys.org)—A team of researchers with members from several institutions in the U.S. and one in Germany has proposed the idea of using an extremely small compass needle to build an ultrasensitive magnetometer. In their paper published in Physical Review Letters, the team describes their idea and the possibility of such a device actually being built.

Current magnetometers are very sensitive, able to detect levels of magnetism that are approximately a trillion times less than that of the Earth’s magnetic field. They achieve this feat by taking advantage of the wobble that occurs when an atom is placed in a magnetic field—such magnetometers are made by placing cells of atomic gas in a magnetic field, the wobbles of the are averaged to arrive at a single measurement. In this new effort, the researchers suggest that a new way to measure magnetic fields could be perhaps as much as 1000 times more sensitive.

The idea behind the still theoretically magnetometer comes from the way a compass needle works—instead of wobbling when exposed to a magnetic field, it simply lines up—at least when viewed from a distance. The researchers have shown that such needles do actually wobble like atoms, when they are very small and placed in a very weak magnetic field. They envision a very tiny needle made of cobalt with all of its atoms aligned in a single direction. When the needed is placed in a weak magnetic field, the angular momentum of the rotation of the needle would be a lot smaller than its intrinsic , which means it would precess, very much like single atoms do. Measuring the precess then would offer a means of measuring the level of magnetism.

Pressure is on DARPA by US Military to speed up on completing the soft Exosuit.

The clothing-like Soft Exosuit has been described as a “Wearable Robot” by the U.S. Defense Advanced Projects Research Agency (DARPA) that’s commissioning universities and research institutions to advance this military technology. The DARPA Soft Exosuit is part of the agency’s Warrior Web program.

A prototype Soft Exosuit had a series of webbing straps around the lower half of the body with a low-power microprocessor and a network of flexible strain sensors. These electronics act as the “brain” and “nervous system” of the Soft Exosuit. They continuously monitor data signals, including suit tension, wearer position (walking, running, crouched) and more.

In 2014, DARPA awarded $2.9 million to The Wyss Institute for Biologically Inspired Engineering at Harvard University to further develop its Soft Exosuit, other versions of which might eventually help persons (military and civilian) with limited mobility.

EPA’s new rules on Carbon Nano Tubes.

On May 16, 2016, the U.S. Environmental Protection Agency (EPA) promulgated, through a direct final rule, significant new use rules (SNUR) for 55 chemical substances that were the subject of premanufacture notices (PMN), including functionalized carbon nanotubes (CNT) (generic). EPA states that it determined that any use of the functionalized CNTs without the use of impervious gloves, where there is potential for dermal exposure; manufacturing the PMN substance for use other than as a thin film for electronic device applications; manufacturing, processing, or using the PMN substance in a form other than a liquid; use of the PMN substance involving an application method that generates a mist, vapor, or aerosol except in a closed system; or any release of the PMN substance into surface waters or disposal other than by landfill or incineration may cause serious health effects or significant adverse environmental effects. EPA states that the following tests would help characterize the health and environmental effects of the PMN substance: “a fish early-life stage toxicity test (OPPTS Test Guideline 850.1400); a daphnid chronic toxicity test (OPPTS Test Guideline 850.1300); an algal toxicity test (OCSPP Test Guideline 850.4500); a 90-day inhalation toxicity test (OPPTS 870.3465) with additional testing parameters beyond those noted at CFR 870.3465, for using the 90-day subchronic protocol for nanomaterial assessment; a two-year inhalation bioassay (OPPTS Test Guideline 870.4200); and a surface charge by electrophoresis (for example, using ASTM E2865-12 or NCL Method PCC-2 — Measuring the Zeta Potential of Nanoparticles).” The SNUR requires persons who intend to manufacture, import, or process any of the 55 chemical substances for an activity that is designated as a significant new use by the direct final rule to notify EPA at least 90 days before commencing that activity. The direct final rule will be effective July 15, 2016. If EPA receives written adverse or critical comments, or notice of intent to submit adverse or critical comments, on one or more of the SNURs before June 15, 2016, EPA will withdraw the relevant sections of the direct final rule before its effective date.

If today’s aviation advances aren’t moving fast enough for you — tray table technology hasn’t budged in decades — you’ll want to check out the futuristic visions of Spanish industrial designer Oscar Viñals.

The Flash Falcon is a future concept jetliner powered by portable fusion reactors. That technology isn’t here yet, of course, but Viñals kind of specializes in “what if?” scenarios.
