In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. Techniques, such as electron microscopy, allowed scientists to identify nucleosomes, the first and most basic level of chromosome organisation. Until now it was known that our DNA is packaged by regular repeating units of those nucleosomes throughout the genome giving rise to chromatin.
Red lead is most familiar to us in orange-red rustproof paint. Artists have treasured the brilliant color of this pigment for their paintings since ancient times. However, various ageing processes cause discoloration of the saturated hue over time.
The major limitation of microscopy is light itself: if we want to see an object smaller than the wavelength of visible light, we cannot use conventional optics. When it comes to imaging cells, the problems compound, since cells often require chemical processing beforehand in order to make them suitable for viewing under a microscope.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have captured the first real-time nanoscale images of lithium dendrite structures known to degrade lithium-ion batteries. The ORNL team’s electron microscopy could help researchers address long-standing issues related to battery performance and safety.
The world's most valuable (€1m) neuroscience prize, The Brain Prize has been awarded, to four scientists, Winfried Denk and Arthur Konnerth (Germany), and Karel Svoboda and David Tank (USA), for the invention and development of two-photon microscopy, a transformative tool in brain research.
Phenom-World is proud to announce the Phenom XL, an addition to the highly successful Phenom desktop SEM product family. The Phenom XL is the world’s first desktop Scanning Electron Microscope (SEM) that allows full imaging of samples up to 100 mm x 100 mm.
Guided by the motto “Connecting Science and Business”, Max Planck Innovation GmbH is a partner of science and industry alike. Its interdisciplinary team provides consulting services and support for scientists from the Max Planck Society with regard to evaluating inventions, applying for patents and founding companies. Max Planck Innovation thus performs the important function of transferring the results of basic research to products that are useful for both the industry and the general public.
Since the determination of the molecular structure of myoglobin in 1957, X-ray crystallography has been the defining tool of structural biology, allowing researchers to determine the structure (and hence the function) of tens of thousands of proteins, nucleic acids, and other biological molecules. But the method can only work for molecules that form large, high quality crystals.
Thanks to the work of an interdisciplinary team of researchers at the Dartmouth Center of Nanotechnology Excellence, funded by the National Institutes of Health, the next-generation magnetic nanoparticles (MNPs) may soon be treating deep-seated and difficult-to-reach tumors within the human body.
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now.
