The likelihood you pick up an infection while riding public transport all depends on how well ventilated the shared space is, according to new research using computer simulations of how viruses spread. A bus with active ventilation poses a significantly lower infection risk than an enclosed room with little ventilation, a study by scientists at the University of Kassel in Germany concludes. "The main finding was that ventilation is the most important factor," explained research assistant Natalie
A little moonlet, too small to be seen from Earth, could be playing cosmic sheepdog by shaping the thin rings around the distant minor planet Chariklo, according to new computer simulations.
Infant exoplanets may not be spherical as astronomers have always assumed. Instead, they may be oblate spheroids, like the 'Smarties' candy found in Europe.
