    Nobels go to maps, LEDs, microscopy

    As if to recognize that walls separating scientific fields are falling, the 2014 Nobel Prizes in chemistry, physics and physiology or medicine went to discoveries that defy single-discipline labels.

    “Biology has turned into chemistry. Chemistry has turned into biology,” says Sven Lidin, chairman of the chemistry Nobel committee. This year’s chemistry laureates...

    Microscopy providing ‘window into the cell’ wins chemistry Nobel

    Breaking the limits of light microscopy by using fluorescence has won three scientists the 2014 Nobel Prize in chemistry. Eric Betzig, a physicist at the Howard Hughes Medical Institute’s Janelia Research Campus in Ashburn, Va., Stefan Hell, a physicist at the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, and W.E. Moerner, a physical chemist at Stanford University, have...

    Microscopy techniques win Nobel Prize in chemistry

    Guest post by Beth Mole

    Fluorescence microscopy allowing researchers to see single molecules just a billionth of a meter across has been awarded the 2014 Nobel Prize in chemistry.

    Since the end of the 19th century, researchers had thought that the resolution of light microscopes would be limited by the wavelength of light, keeping the features inside living cells out of sight.

    Blue LEDs win Nobel Prize in physics

    The invention of blue light-emitting diodes that are central to the energy-efficient lights illuminating homes, offices and electronic displays has earned three scientists the 2014 Nobel Prize in physics. Isamu Akasaki of Meijo University and Nagoya University in Japan, Hiroshi Amano of Nagoya University and Shuji Nakamura of the University of California, Santa Barbara will split the roughly $...

    Blue light-emitting diode earns three researchers Nobel Prize in physics

    Guest post by Andrew Grant

    The invention of blue light-emitting diodes has been awarded the 2014 Nobel Prize in physics. Blue LEDs, when combined with red and green diodes, produce an energy-efficient and environmentally friendly source of white light when compared with incandescent and fluorescent light bulbs.

    LEDs use semiconducting materials like the ones in computers and...

    Neuroscientists garner Nobel for discovering brain’s ‘inner GPS’

    Mapping the brain’s GPS system has earned three neuroscientists the 2014 Nobel Prize in physiology or medicine. John O’Keefe of University College London shares the prize with husband-and-wife duo May-Britt Moser and Edvard Moser of the Norwegian University of Science and Technology in Trondheim.

    “I’m delighted that three great friends and three great scientists have deservedly won this...

    Brain’s map cells win three scientists Nobel Prize

    Guest post by Tina Hesman Saey

    The discovery of brain cells that provide a sort of “inner GPS” has been awarded the Nobel Prize for physiology or medicine.Half of the prize goes to John O’Keefe of University College London. In 1971, he found that “place cell” neurons in the brain’s memory center become active when rats are in certain positions in a maze. Other place cells become active...
