MIT scientists have created a material, the cracks on which are tightened themselves.

Engineers from the Massachusetts Institute of Technology (MIT) presented a material capable of self-regeneration. He independently tightens the cracks appearing on it. The basis of the ability to restore new material is the process of photosynthesis. With it, plants turn light into carbon dioxide and oxygen. The researchers connected the chloroplasts responsible for photosynthesis in … Continue reading MIT scientists have created a material, the cracks on which are tightened themselves.

The world’s first medical imaging scanner that can capture a 3-D picture of the whole human body at once

The brainchild of UC Davis scientists Simon Cherry and Ramsey Badawi, EXPLORER is a combined positron emission tomography (PET) and x-ray computed tomography (CT) scanner that can image the entire body at the same time. Because the machine captures radiation far more efficiently than other scanners, EXPLORER can produce an image in as little as … Continue reading The world’s first medical imaging scanner that can capture a 3-D picture of the whole human body at once

Canadian researchers are close to creating batteryless smart devices.

The techers at the University of Waterloo have taken a huge step towards making smart devices that do not use batteries or require charging. They found a way to hack radio frequency identification (RFID) tags, the ubiquitous squiggly ribbons of metal with a tiny chip found in various objects, and give the devices the ability … Continue reading Canadian researchers are close to creating batteryless smart devices.

Robust fuel cell runs on methane at practical temperatures.

A group of scientists led by Meilin Liu from the Georgia Institute of Technology created a new fuel cell, which had been reimagined with the help of a newly invented fuel catalyst. This catalyst uses readily available methane instead of usual high-priced hydrogen fuel. It gonna make its production much cheaper. Hydrogen is the best … Continue reading Robust fuel cell runs on methane at practical temperatures.

Super cheap, super compact, super accurate: russian physicists have upgraded a usual diode laser to an ultra-precise instrument.

A group of researchers from the Russian Quantum Center (RQC), the Moscow Institute of Physics and Technology (MIPT), Lomonosov Moscow State University (MSU), and Samsung R&D Institute Russia have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer. This makes their device a useful … Continue reading Super cheap, super compact, super accurate: russian physicists have upgraded a usual diode laser to an ultra-precise instrument.

Engineers have taught the quadcopter to continue flying with the loss of one propeller.

Engineers from the Delft University of Technology (The Netherlands) have created a system that allows the quadrocopter to stay airborne and maintain balance if one of its propellers is damaged. Usually, if one of the propellers breaks, the quadrocopter loses its orientation and falls. The researchers created a system that, based on accelerometer and gyroscope … Continue reading Engineers have taught the quadcopter to continue flying with the loss of one propeller.
