Discovery, at Palomar Telescope (San Diego, CA, USA), of the closest (type 1) supernova found in the past 25 years. It is “only” 21 million light-years away, in the Pinwheel Galaxy.
To locate it, take the last two stars in the handle of the “big dipper” formed by the Ursa Major constellation, and form an equilateral triangle heading North. You should be able to see it by Friday night.
Stuxnet is a very sophisticated virus, famous for having destroyed nuclear installations in Iran. Variants are now being developed. They can attack, as Stuxnet did, so called “SCADA” (Supervisory Control And Data Acquisition) IT systems, which are used to monitor, in real time, large scale technical installations, for instance to control industrial machines and processes, or to supervise the production and distribution of energy (electricity – with smartgrids – gas, oil) or water with potentially catastrophic consequences (massive power outage or water shortage, explosions, toxic spills…).
The risk strategy of industrial companies, whatever their size, must increasingly take into account this kind of threat.
The following video, recorded in 2006, predicts somehow the H1N1 flu pandemics of 2009 and warns us about the risk of H5N1 avian flu, which is still high, according to a recent declaration of the FAO.
