Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4 feet vertically. It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. Handle uses many of the same dynamics, balance and mobile manipulation principles found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.
A Navy SEAL, broad-chested and strongly built, floats peacefully on the water, as his recent deployment to a war-torn country becomes a distant memory.
Sealed inside a pitch-black sensory deprivation tank in the Mind Gym at Navy SEALs headquarters in Norfolk, Va., electrodes attached to his head, he has reached an altered state of consciousness referred to as “ecstasis” or “stepping outside oneself.”
It’s a state achieved by many others throughout time. High-performance athletes are in ecstasis when they ski down huge mountains or surf giant waves. Monks attain it after years of meditation. Mystics feel it when they have visions. And the US government uses it to try to reset their most elite warriors after brutal battles abroad.

In Brief
Rocket science isn’t easy. Ask any engineer. Rocket science isn’t cheap. Just ask NASA. Fortunately, in recent years, a number of commercial spaceflight companies have stepped up to the plate in order to help national space agencies extend their reach into the final frontier.

Scientists have figured out how to inject a conducting solution into a rose cutting, and have it spontaneously form wires throughout its stem, leaves, and petals to create fully functioning supercapacitors for energy storage.
The so-called e-Plant was able to be charged hundreds of times without any loss on the performance, and the team behind the invention says it could allow us to one day create fuel cells or autonomous energy systems inside living plants.
“A few years ago, we demonstrated that it is possible to create electronic plants, ‘power plants’, but we have now shown that the research has practical applications,” says one of the team, Magnus Berggren from Linköping University in Sweden.

It consists of two thin, flexible polymer films (black) with source, drain, and gate terminals, connected by an electrolyte of salty water that permits ions to cross. A voltage pulse applied to the “presynaptic” layer (top) alters the level of oxidation in the “postsynaptic layer” (bottom), triggering current flow between source and drain.

Stanford University and Sandia National Laboratories researchers have developed an organic artificial synapse based on a new memristor (resistive memory device) design that mimics the way synapses in the brain learn. The new artificial synapse could lead to computers that better recreate the way the human brain processes information. It could also one day directly interface with the human brain.
The new artificial synapse is an electrochemical neuromorphic organic device (dubbed “ENODe”) — a mixed ionic/electronic design that is fundamentally different from existing and other proposed resistive memory devices, which are limited by noise, required high write voltage, and other factors*, the researchers note in a paper published online Feb. 20 in Nature Materials.

A super-material that bends, shapes and focuses sound waves that pass through it has been invented by scientists.
The creation pushes the boundaries of metamaterials — a new class of finely-engineered surfaces that perform nature-defying tasks.
These materials have already shown remarkable results with light manipulation, allowing scientists to create a real-life version of Harry Potter’s invisibility cloak, for example.
British and Czech scientists have unveiled a new “super laser” that they claim is the most powerful pulse laser available today.
The laser was developed by Britain’s Central Laser Facility (CLF) and Czech research and development project HiLASE (high average power pulsed laser). The 22-ton device has been dubbed Bijov after a mythical Czech strongman, and it cost $48 million to build.
Bijov has an average power output of 1,000 watts — a world record for pulse lasers. It first crossed this “magical barrier” on December 16, 2016, and HiLASE physicist Martin Divoky told AFP that it is “10 times as powerful” as any other laser of the same type.

Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible.
Understanding a stem cell’s fate—the type of cell it will eventually become—and how far along it is in the process of development can help scientists better manipulate cells for stem cell therapy.
The beauty of the method is its simplicity and versatility, said Prabhas V. Moghe, distinguished professor of biomedical engineering and chemical and biochemical engineering at Rutgers and senior author of a study published recently in the journal Scientific Reports. “It will usher in the next wave of studies and findings,” he added.
