An article published in the journal “Computers & Geosciences” describes a research into the possibilities of combining artificial intelligence, Twitter and what is called citizen science to create early warning systems for flood-prone communities. A team of researchers from the British University of Dundee led by Roger Wang worked to create solutions that can detect as quickly as possible the first signs of danger to activate countermeasures.

IBM has announced the company’s progress in the field of quantum computing. A 20-qubit processor will be available in commercial systems with offerings within its specific IBM Q quantum systems program. Customers will be able to access its services via cloud and develop applications using the QISKit project, an open source development kit to program on quantum computers. IBM also announced the creation of a quantum processor prototype with 50 qubits.

An article published in the journal “Nature Communications” describes the development of a new type of quantum computer that, according to the authors, resolves many problems with this type of computer. A team of engineers at the University of New South Wales, Australia, invented a new architecture based on flip-flop qubits that is supposed to make the production of large-scale quantum chips much simpler and cheaper.

The news came that yesterday the writer Jerry Pournelle died in his sleep at his home in Studio City, California.

His military experience, both at the front and in weapon development projects, also accompanied Jerry Pournelle’s career as a writer. Today, military science fiction has become an acknowledged subgenre that has its importance and its fans but in the past it had little consideration and Jerry Pournelle’s works were crucial to its development.

Jerry Pournelle was a complex person with a life spent working in many different fields so it’s a case where every label would be trivial and would only describe a small part of him. It’s thanks to all the experiences he accumulated that in his stories he created complex situations in which the characters ended up finding solutions to problems that were far from politically correct.

An article published in the journal “Nature” describes the application of neural networks to gravitational lensing. A team of researchers reduced from a few weeks to a few seconds the time needed to analyze complex space distortions in images captured thanks to gravitational lenses. This could greatly facilitate this type of task with great benefits for astronomical research.
