Google has announced it’s closing its social network Google+ to consumers to remain open to enterprise users. The transformation will take place in 10 months, giving users time to make a copy of their messages. The news was provided along with the revelation of a security problem that left the data of many users visible to anyone who could exploit it.

A settlement was reached between Elon Musk and the Securities and Exchange Commission (SEC), the authority that monitors the US stock market, which put an end to the fraud investigation that began after the businessman declared on Twitter that he wanted Tesla to go private and already secured the funding to do it. Musk will resign as Tesla Chairman and will not be able to hold that position for at least 3 years. Also, he and Tesla will pay a $20 million penalty each.


Microsoft has announced the release of the sources of versions 1.25 and 2.0 of its MS-DOS operating system, which were made available on the GitHub website, under the MIT free / open source license. In 2014 the same sources were released to the Computer History Museum but with a restrictive license, for historical reasons. The released versions are very old and Microsoft will not accept pull requests to modify them sent through the GitHub system but anyone can freely not only read the assembly code but also experiment with it, perhaps on a virtual machine.

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.
