Forensic Future: Around our country there are human remains sitting at forensic storage sites unidentified but for a case number. They are potentially the loved ones of those still living, but there has been no way of really knowing for sure. Catalyst investigates a real life unsolved mystery of a man who's body has been exhumed from the grave whilst revealing how cutting edge forensics, together with developments in DNA testing are working towards, quite literally, putting a face to the nameless.
Alien Megastructure: Something massive, with roughly one thousand times the area of Earth, is blocking the light coming from a star about 1400 light years away, and nobody is quite sure what it is. Without a natural explanation, even the world's most reputable astrophysicists have been forced to consider the possibility of an alien-built megastructure. Such an extraordinary idea would, of course, require extraordinary evidence, which is exactly what we're in search of as we turn our eyes and telescopes towards this perplexing celestial object.
