Developed an "immortal" lithium-ion battery

A simple lithium-ion battery is recommended to not to bend or twist, because the components contained in it are very sensitive to water and can explode or catch on fire when contacting it. But the new batteries created by scientists, you can not only bend, but also tie a knot, absolutely not worrying about your own health.

Work on a flexible lithium-ion battery began in 2015, when the US military chemical laboratory specialists together with scientists from the University of Maryland created a "safe and environmentally friendly" battery, just adding a little salt. Developers were not limited by adding salt in battery, but turned the electrolyte into a gel, which allowed literally to bend out of the new battery steering wheel.

Missile technologies open up big opportunities for the "Roadster"

The announcement of the most fashionable supercar from Tesla was held recently, but the head of the company Ilon Musk is already arguing on Twitter about the future of his new cars. According to him, the car, which will be produced in two years or less, will be only a basic model, whose capabilities will eventually increase due to rocket technologies.

"Should clarify that this is the base model performance. There will be a special option package that takes it to the next level. "wrote Musk on his Twitter account.

Many Musk projects borrow technologies from each other. So, the automobile company Tesla uses the same innovative welding that is used in the construction of SpaceX rockets. Probably, something from the developments of SpaceX is already in use or planned to be introduced into the production of auto.

"I do not claim that the next Roadster will be able to make flights and jumps, but everything can be ...", Tesla Head said, adding that all this is just safety issues, since missile technologies offer great opportunities for the manufacturer.

The first "Roadster" from Tesla will be on sale by 2020, will accelerate to 100 kilometers per hour in 1.9 seconds and will be able to develop a maximum speed of 400 kilometers per hour.

Lockheed Martin has developed an exoskeleton for the military landing

Researchers from the University of Michigan have determined that the FORTIS K-SRD exoskeleton, designed by Loосkheed Martin, can significantly reduce the fatigue of the military. The device, attached to the soldiers' feet, reduces the load and increases endurance.

Researches was funded by an independent organization, so scientists talk about the objectivity of their research. They say that they tested the devices on a treadmill, the angle of which varied periodically to 15 degrees. Subjects were loaded with backpacks weighing 20 kg, and during the tests the speed of the treadmill was changed. At the same time, all life indicators were read out and it was determined how much energy was spent by the experimental subjects to perform the tasks.

Invented a more accurate method of gene editing

Scientists at Yale University reported on the creation of a more accurate and effective technology for editing the genome of living organisms. The new method allows you to get rid of the shortcomings of modern technologies, including - CRISPR / Cas9.

"The existing technology can be compared to a saw, and this method - with a scalpel that allows you to make precise genetic changes with high efficiency in a lot of places in the eukaryote genome," says Farren Isaacs.

Modern gene-editing technologies, for example, CRISPR / Cas9, usually break two DNA strands when when genetic changes are being implemented. In order to repair the chain, the body makes efforts that can be lethal for the cell. However, sometimes these gaps remain unresolved or create tiny errors in the DNA sequence that change their functions.

3D-printed 'bionic skin' could give robots the sense of touch

Engineering researchers at the University of Minnesota have developed a revolutionary process for 3D printing stretchable electronic sensory devices that could give robots the ability to feel their environment. The discovery is also a major step forward in printing electronics on real human skin.

"This stretchable electronic fabric we developed has many practical uses," said Michael McAlpine, a University of Minnesota mechanical engineering associate professor and lead researcher on the study. "Putting this type of 'bionic skin' on surgical robots would give surgeons the ability to actually feel during minimally invasive surgeries, which would make surgery easier instead of just using cameras like they do now. These sensors could also make it easier for other robots to walk and interact with their environment."

McAlpine, who gained international acclaim in 2013 for integrating electronics and novel 3D-printed nanomaterials to create a "bionic ear," says this new discovery could also be used to print electronics on real human skin. This ultimate wearable technology could eventually be used for health monitoring or by soldiers in the field to detect dangerous chemicals or explosives.

In Japan, created a spherical flying display

Japanese regional provider NTT Docomo has created a spherical display that can fly. This development is based on a multi-copter. This device can fly and simultaneously show something. Thus, the information will receive a large number of people. The presentation of the development has already passed in the city of Chiba.The whole design is on a powerful quadrocopter. A sphere is attached to it from above. The frame diameter is 88 centimeters. On this sphere there is a screen. It was created from small LEDs, which are arranged horizontally, but they go in a circle. The design is made in such a way that with its movement on the screen there is then a static, then moving picture. Thus, it is possible to adjust the output of the image on the display.

SolarGaps - blinds, producing electricity

Usual blinds are used to protect the premises from sunlight. The creator of the SolarGaps entrepreneur Eugene Eric expanded their functions by adding lamellas to massive monocrystalline solar cells. This behind the blinds does not only block sunlight, but also generate electricity.

In addition, a light sensor is mounted in the blinds to track the location of the Sun. Now, depending on where it is, automatically change the slope angle of slats, put them to the best efficiency. There is also a "managed" version using a mobile application for a smartphone.In addition, the application allows you to open and close the blinds, including at certain times, monitor the amount of energy received, and also open when someone enters the room.
