Niacin or vitamin B3 has the ability to prolong life, as demonstrated by Michael Ristow, from the Federal Polytechnic School of Zurich (Switzerland), in a study with worms of the species Caenorhabditis elegans.

Prepubertal rodents prevent adult males from copulating with them by secreting a pheromone through their tears. The discovery is the first step towards understanding how a sensory system, in this case the olfactory, can regulate social behavior.
According to the traditional model, black holes are defined based on their mass and their angular momentum or speed of rotation. Once its progenitor has collapsed (a massive star, for example), its memory is lost forever. All that would be left then would be a quiescent black hole, almost featureless: all black holes, mass and angular momentum apart, would look similar. According to this concept, all the matter that forms or falls into the hole disappears completely and is inaccessible to an external observer.
