Probiotic bacillus eliminates staphylococcus bacteria – A new study shows that a 'good' bacterium commonly found in probiotic digestive supplements helps eliminate Staphylococcus aureus, a type of bacteria that can cause serious antibiotic-resistant infections. The researchers unexpectedly found that Bacillus bacteria prevented S. aureus bacteria from growing in the gut and nose of healthy individuals.

An exoplanet inflated like a balloon – Although helium is a rare element on Earth, it is ubiquitous in the universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only detected recently in the atmosphere of a gaseous giant by an international team. The team has observed for the first time how this gas escapes from the overheated atmosphere of an exoplanet, literally inflated with helium.
