A new microscope can resolve features deep below the surface of samples. "The new system advances the original super-resolution fluorescence microscopy by incorporating the deformable mirrors into a microscope using two objectives, one above and one below the sample, and introducing a set of new algorithms to pinpoint molecular positions of proteins deep inside cells. The system allows researchers to resolve details far smaller than the wavelength of light."
"The technology was demonstrated by imaging cellular components, including synaptonemal complexes, which link chromosomes together; mitochondria and the endoplasmic reticulum, which are critical for cellular functions; the cilia, which protrude from cells like tiny antennas; and bacteriophages, which are viruses about 50 nanometers in diameter that infect bacteria."
A new ultra-high resolution 'nanoscope' is capable of taking 3-D images of an entire cell and its cellular constituents in unprecedented detail, an advance that could reveal biological phenomena never before seen and bring new medical insights.
A one-kilobyte atomic-memory device is described in a new paper in the journal Nature Nanotechnology. Scientists say it can pack hundreds of times more information per square inch than the best currently available data-storage technologies.
Sweden is moving to a six-hour working day in a bid to increase productivity and make people happier. Employers across the country have already made the change, according to the Science Alert website, which said the aim was to get more done in a shorter amount of time and ensure people had the energy to enjoy their private lives.
