Astronomers have discovered a supermassive black hole at the center of a galaxy just 1.5 billion years after the Big Bang that is consuming matter at a phenomenal rate -- over 40 times the theoretical limit.
Dance of electrons measured in the glow from exploding neutron-stars
The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole.
Violating Bredt's rule: Chemists just broke a 100-year-old rule and say it's time to rewrite the textbooks
According to Bredt's rule, double bonds cannot exist at certain positions on organic molecules if the molecule's geometry deviates too far from what we learn in textbooks.
