Oumuamua is a comet after all
• When a reddish cigar-shaped rock came spinning through the solar system last October, scientists could not figure out what it was. It didn't have a comet's tail so it must be an asteroid. Later studies have, however, shown that the Oumuamua is indeed a comet but with an invisible tail. Like all comets, the gases in its tail fired its exit from the solar system.
• In May, archaeologists uncovered a man's skeleton in Pompeii. He seemed to have been killed by a giant block of stone while fleeing the volcanic eruption of Mount Vesuvius in 79 AD. The head and torso were missing. These have recently been found. They show that the man died of asphyxiation from the ash. The stone was probably part of a building that collapsed on him later.
• A recent study published in the Proceedings of the Royal Society B shows that bumblebees are doing much better in cities than in farmlands. Scientists established 38 bumblebee colonies in the cities, suburbs and farmlands. It was seen that the farmland colonies died out first. The suburban and city colonies fared more or less the same. Perhaps modern farm life -with fewer flowers and more pesticides - was too stressful for the bees.
