The impact of an asteroid that about 65 million years ago caused the extinction of the dinosaurs is an event now known also outside of the scientific field. However, a study published in the journal “Geochemistry, Geophysics, Geosystems” reconstructs the impact of a much larger asteroid, with a diameter estimated to be between 37 and 58 km (23 to 36 miles), occurred about 3.26 billion years ago.
Daniel Levner, a bioengineer of the Wyss Institute at Harvard University, and some colleagues of the Bar Ilan University in Ramat-Gan, Israel, built nanobots, microscopic robots made from DNA. They were inserted into cockroaches to test their ability to perform logical operations that will allow to diagnose diseases or deliver drugs in an extremely targeted way.

A sentient asteroid wanders the cosmos. In the course of its long life, it never found creatures like him and has learned to feel his way around the universe without the need for common perception senses. After many travels, it enters a solar system in which there are life forms very different from it born on the third planet who have expanded on other planets.
CERN scientists who work with the Large Hadron Collider (LHC) (photo ©Julian Herzog) announced that operations have started to reactivate the largest particle accelerator in the world. In February 2013, the LHC was switched off in what was called “Long shutdown 1” (LS1), needed to upgrade some of the equipment and perform other maintenance tasks.
Gamebuino is a project to create a retro videogame console, like the old-fashioned 8-bit ones such as the Nintendo Game Boy, based on Arduino, an electronic platform with circuit diagrams that are distributed as free hardware with a software kit too free as well. The fundraiser with the crowdfunding method on the Indiegogo website, which started on March 12, 2014, is having a great success and will continue until April 28, 2014.
