Neutrons

  • Forget steel, forget diamond and even forget graphene – “nuclear pasta” may be the strongest material in the universe. This strange substance is formed in the intense pressures inside neutron stars, and researchers have now run computer simulations to test just how strong it is.
  • In August 2017, astronomers observed a collision between two neutron stars so powerful it produced gravitational waves, flares in visible light, radio waves, x-rays and a gamma ray burst. Now that things have quietened, astronomers have studied the strange object created in the cosmic collision.
  • Last year astronomers around the world witnessed the merger of two neutron stars as gravitational waves, light, radio and gamma rays, but the aftermath of the mashup hasn’t played out quite as expected. Rather than fade over time, the afterglow has continued to brighten.
  • Before cures for diseases such as Alzheimer's can be found, scientists need a better understanding of how neurons in the brain communicate with one another. Researchers recently took a step towards that goal, by developing the smallest LED probes ever implanted in a living brain.
  • Science
    Sandia National Laboratories is working its Mobile Imager of Neutrons for Emergency Responders (MINER) – a nuclear device detector capable of narrowing a search to within a city block without door-to-door sweeps.
  • Science
    Neutrons have unique properties making them better than light, electrons, or x-rays for studying the physics and chemistry going on inside an object. Scientists at MIT's Nuclear Reactor Laboratory have developed new approaches to neutron optics, using them in the world's first neutron microscope.
