A New Organism’s “Alien” Reproduction, Levitation and Dark Matter, and Genetic Evidence of an Ancient Killer

This week in stories we’re covering at The Debrief… Scientists say they have discovered an organism whose behavior mirrors the reproductive horror depicted in the “Alien” films. Elsewhere, physicists report that a recent levitation experiment could signal a breakthrough in the search for dark matter. Also, new genetic evidence of an ancient killer has surfaced in ancient medieval texts. And finally, a 15,000-year-old cave discovery in Ireland could push back evidence of the first humans on the island by 5,000 years.

Here’s a look at all the stories we’re tracking right now at The Debrief:
