Come on out, exotic matter, don't be shy! Let's ride a TARDIS with the Doctor! <♥>

Using the Bridge Inspector HoloLens app created by the Cambridge team, engineers are able to inspect the condition of infrastructure in office as if they were standing on site in front of the real asset. "Bringing a bridge to life at full scale while still being aware of your surroundings is a major time saver for experienced inspectors," explains Dr Ioannis Brilakis.

In the study, the research team reported that red-light absorbing carbon nitride (C₃N₄) sheets lead to remarkable proliferation and osteogenic differentiation by runt-related transcription factor 2 (Runx2) activation, a key transcription factor associated with osteoblast differentiation. (...)

Professor Kim and Professor Suh examined the C₃N₄sheets. They discovered that this material absorbs red light and then emits fluorescence, which can be used to speed up bone regeneration. Professor Kim's team synthesized carbon nitrogen derivatives from melamine compounds. Then, they analyzed the light-absorbing characteristics of C₃N₄sheets at a wavelength range of 455-635 nanometers (nm). As a result, the C₃N₄sheets were found to emit fluorescence at the wavelength of 635 nm when exposed to red light in a liquid state. At this time, the released electrons induced calcium to accumulate in the cytoplasm.

“This is exciting as all subjects accomplished the tasks using a completely noninvasive technique. We see a big potential for this research to help people who are paralyzed or have neurodegenerative diseases to become more independent without a need for surgical implants.”

Places where precision is required often uses industrial automation. These include hazardous environments, heavy lifting or repetitive production. But more often than not, the robotics are working alongside humans on factories’ production lines. However, they come with the risk of injury as the robot will continue along its path no matter the obstruction. (...)

The robot can perform a variety of tasks. These tasks include positioning, drilling, assembling and any automated job that requires some form of dexterity. The Franka Emika uses strain gauges to measure the forces on its motors, which classifies the Franka as a torque-controlled robot. It can not only detect minor collisions but also halt the action to prevent any damage and continue once the path is clear.

“The extremely flexible mesh, made of gold wires sandwiched between layers of a polymer, easily coils into a needle so it can be injected rather than implanted, avoiding a more extensive surgery. Part of the mesh sticks out though the brain and a hole in the skull so that it can be wired up to a computer that controls the electric jolts and measures the neurons’ activity. But eventually, Lieber says, the controls and power supply could be implanted in the body, as they are in today’s systems for deep brain stimulation. “
