“But as a neuroscientist and psychologist, I have no use for the soul. On the contrary, all functions attributable to this kind of soul can be explained by the workings of the brain.”

In Brief.
Tesla and SolarCity are working on making their cars capable of powering a household, and even the entire grid. Using vehicle-to-grid technology, Tesla may be on to something here, and its more than just saving on your electric bills.

The lights dimmed inside the Shenzhen Bay Sports Stadium as the countdown to the match began. “Wu, si, san, er, yi!” A chime sounded and two teams of robots sprang into action across an intricately constructed battlefield. In the stands, thousands of fans cheered, and groups of small children beat red and blue balloons together, producing a percussive roar.
Each team had four rovers, nimble infantry units that quickly spread over the terrain. The rovers were shaped like small cars, but could also slide side to side, strafing like water bugs over the surface of a lake. They fired small plastic marbles from cannons mounted on top of their frames. Lumbering alongside the nimble rovers was each team’s hero, a larger tank-like robot that could fire the small plastic marbles as well as more powerful golf balls.
The heavy favorite in this matchup of RoboMasters, an annual competition held each summer, was team 1.5S, returning champions hailing from China’s University of Electronic Science and Technology in the Sichuan province. They were taking on StarPro, from the Huazhong University of Science and Technology in Wuhan.

Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow’s computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip, as outlined Nature Photonics. This fulfills one condition for the use of photonic circuits in optical quantum computers.
“Experiments investigating the applicability of optical quantum technology so far have often claimed whole laboratory spaces,” explains Professor Ralph Krupke of the KIT. “However, if this technology is to be employed meaningfully, it must be accommodated on a minimum of space.” Participants in the study were scientists from Germany, Poland, and Russia under the leadership of Professors Wolfram Pernice of the Westphalian Wilhelm University of Münster (WWU) and Ralph Krupke, Manfred Kappes, and Carsten Rockstuhl of the Karlsruhe Institute of Technology (KIT).
The light source for the quantum photonic circuit used by the scientists for the first time were special nanotubes made of carbon. They have a diameter 100,000 times smaller than a human hair, and they emit single light particles when excited by laser light. Light particles (photons) are also referred to as light quanta. Hence the term “quantum photonics.”

Robert Zubrin is best known for his advocacy of the manned exploration of Mars.
Zubrin also had a design for interplanetary propulsion called the Nuclear Salt Water Rocket.
A nuclear salt-water rocket (NSWR) is a theoretical type of nuclear thermal rocket. A conservative design for the rocket would be fueled by salts of 20 percent enriched uranium or plutonium. The solution would be contained in a bundle of pipes coated in boron carbide (for its properties of neutron absorption). Through a combination of the coating and space between the pipes, the contents would not reach critical mass until the solution is pumped into a reaction chamber, thus reaching a critical mass, and being expelled through a nozzle to generate thrust.

The Oxfordshire-based firm has been developing a turbine that combines both jet and rocket technologies to achieve rates five times the speed of sound, to fly anywhere in the world in just four hours.
Rather than aiming for a demonstrator that can achieve more than 150,000 lb thrust, the firm will instead now target an engine size capable of roughly 44,000 lb thrust, according to Aviation Week Network.

Crohn’s Disease is a legendarily difficult disease to not only identify but to treat or cure. The disease affects the intestines and digestive tract, stemming from bacteria in those areas building up and leading to serious side effects. It affects more than half a million people in the United States and is brutal – with the possibility of diarrhea, weight loss, fatigue, ulcers, malnutrition, and eventually colon cancer, liver disease or osteoporosis.
Treatment is limited, with the current best options being medicine to limit inflammation and prevent symptoms. There is no complete cure, only efforts to make life as comfortable and normal as possible for those afflicted. Without a specific target at which to aim some sort of treatment, the options for permanently reducing or removing symptoms and health risks are few and far between. Before now, the only thing scientists thought they knew about the disease’s cause was that E Coli was involved.
However, recent studies have led researches to believe that they have narrowed down other bacteria that contributes to the onset and ongoing symptoms of Crohn’s. Experts at the Center for Medical Mycology at Case Western Reserve and University Hospitals Cleveland Medical Center (wow, is that a mouthful!) think they have pinpointed two additional bacterial strains that contribute to the disease. They studied a cross section of people – those with the disease, those with the disease whose family members did not have it, and those without it – to attempt to identify common details in their biological tests. Such a diverse group of subjects is required not only due to the importance of adhering to the scientific method but because Crohn’s can be caused by genetics and environmental factors.
