Mouse brain cells

An article published in the journal “Nature Communications” describes a new technology developed to obtain highly detailed images at very small scales of what happens inside living cells. A team of researchers combined the use of heavy water as a tracer with the technique known as stimulated Raman scattering to be able to obtain images of metabolic activities. The idea is to use it for medical purposes, completing other exams, and biological research.

The Mexican city of Ensenada has become famous in recent days because the local police declared that they have been able to arrest over 500 criminals thanks to the use of a drone in the last 4 months. According to the statistics reported, that led to an overall crime reduction by 10% overall and in particular a drop in burglaries by 30%.

IBM and the US Department of Energy’s Oak Ridge National Laboratory (ORNL) announced the supercomputer Summit stating that it’s the fastest in the world. Peak performances are declared at 200 petaflops, which are eight times those of the previous ORNL supercomputer, called Titan, activated in October 2012 and for a few months the most powerful in its category. It’s a system designed for scientific applications with an eye to artificial intelligence.

The announcement arrived of the agreement that sees Microsoft buy the hosting service for software projects GitHub for $7.5 billion in Microsoft stock. The rumors of the deal begun last week but two years ago Microsoft had already attempted the acquisition.

GitHub is a hosting service for software projects that use the Git distributed version control software, one of the inventions of Linus Torvalds, famous above all for being the father of the Linux operating system. The company behind the service was founded in 2008 with its office in San Francisco, initially as Logical Awesome and since 2010 as GitHub, Inc. rapidly achieving great success.

An article published in the journal “Applied Materials and Interfaces” describes a scalable process to produce graphene sheets relatively cheaply and quickly, with speeds of 5 centimeters per minute. A team of MIT researchers applied a technique based on chemical vapor deposition to synthesize high-quality graphene of uniform quality. This process allows to create graphene with nanopores, microscopic holes of the desired size to use it as a filter.
