A team of U.S. and U.K. scientists has generated the end-to-end gapless DNA sequence of the human X chromosome. A telomere is the end of a chromosome that protects the interior of a chromosome from damage during cell division. Image credit: Darryl Leja, NHGRI. After nearly two decades of improvements, the reference sequence of the human genome is the most accurate and complete vertebrate genome sequence ever produced. However, there are hundreds of...

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.
