  New microscope makes movies of tiny live specimens
  تاریخ  ثبت خبر : 1393/08/03

A new microscopy technique allowing biologists to see more detail in living specimens without damaging them with intense light has been developed by researchers in the US, Europe and Japan. The method uses interacting beams of light to create an ultrathin "light sheet" that passes through the sampl

  Dark matter could light up giant mirror
  تاریخ  ثبت خبر : 1393/08/03

A large metallic mirror previously used as a prototype for a cosmic-ray observatory will be reused by physicists in Germany to hunt for "hidden photons". These exotic and hitherto unseen cousins of normal photons could account for some dark matter – the mysterious and invisible substance that appea

  Isamu Akasaki, Hiroshi Amano and Shuji Nakamura win 2014 Nobel Prize for Physics
  تاریخ  ثبت خبر : 1393/08/03

The 2014 Nobel Prize for Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for their development of blue LEDs. The prize is worth SEK 8m (£690,000) and will be shared by the three winners who will receive their medals at a ceremony in Stockholm on 10 December. Akasaki is

  Quantum effects bridge the gap
  تاریخ  ثبت خبر : 1393/08/03

Tunneling is an intriguing aspect of quantum mechanics whereby a particle is able to pass through a classically insurmountable barrier. Theoretically, quantum plasmonic tunneling is only noticeable when plasmonic components are very closely spaced -- within half a nanometer or less. However, resea

  New experiment provides route to macroscopic high-mass superpositions
  تاریخ  ثبت خبر : 1393/08/03

Standard quantum theory places no limit on particle size and current experiments use larger and larger particles, which exhibit wave-like behaviour. However, at these masses experiments begin to probe extensions to standard quantum mechanics, which describe the apparent quantum-to-classical transi
