NASA’s Fermi telescope reveals the power source behind monster supernovae

Key Points

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast was powered by a rapidly spinning magnetar, an exotic neutron star with unbelievably strong magnetic fields. The event, called SN 2017egm, erupted 440 million light-years away and may help explain why some supernovae become extraordinarily bright.

Genetically modified worms can now produce and deliver drugs inside a living body, scientists say In a proof-of-concept lab experiment, scientists demonstrated that intestinal parasites could make and release therapeutic agents inside a living host. Scientists genetically tweaked a tiny, worm-like parasite to produce a life-saving antitoxin from inside a living host. In a first-of-its-kind study, researchers modified the hookworm Ancylostoma ceylanicum so that it produces antibodies that...
