There's a new, cheap meningitis vaccine and after just 6 months it managed to reduce the number of new cases in three west African countries to almost zero. It costs just 50 cents and is more potent then old ones. Still to vaccinate all children in the meningitis belt millions will be needed.

The emergence of new vaccine manufactures forced big pharma companies to compete harder for contracts to supply UNICEF with childhood vaccines over the next five years and drove down the prices for vaccines for preventable diseases. At least in poorer countries but they are also the ones who need it most. Richer ones have more problems with those who refuse vaccinations endangering not only themselves but also those around them. Of all the stupid conspiracy theories and scams for publicity the one that made people believe vaccines cause autism is probably most harmful. There is no medicine with less side effects and more positive results.

In more distant news Voyagers are traveling through the last barrier to leave Solar System. They are crossing through a border of Sun's magnetosphere where magnetic field lines are snapping and reconnecting sculpting the wind of high-energy particles coming from space into discrete bubbles that are many tens of millions of kilometres wide. Looks like the border is much more violate then we thought.

Even further away there were some strange supernoveae detected. The fact that they lack hydrogen is not unique but that they burn oxygen is. Seems the yesterday's poster was even more wrong then we though - some stars do burn oxygen. At least when they explode. And this really makes the explosions bright.

And finally someone took and unified the theories of multiverse and many worlds into one. You know the ones that postulate that either cosmos constantly splits into parallel universes in which every conceivable outcome of every event happens or our universe is part of a larger multiverse. The end result is pretty much the same and most people never learn the difference anyway. No you no longer need to.
