Watch Molecular Dynamics

Authors: George Rajna

Researchers have developed a fast and practical molecular-scale imaging technique that could let scientists view never-before-seen dynamics of biological processes involved in neurodegenerative diseases such as Alzheimer's disease and multiple sclerosis. [26] A research team led by Professor YongKeun Park of the Physics Department at KAIST has developed an optical manipulation technique that can freely control the position, orientation, and shape of microscopic samples having complex shapes. [25] Rutgers researchers have developed a new way to analyze hundreds of thousands of cells at once, which could lead to faster and more accurate diagnoses of illnesses, including tuberculosis and cancers. [24] An international team including researchers from MIPT has shown that iodide phasing—a long-established technique in structural biology—is universally applicable to membrane protein structure determination. [23] Scientists in Greece have devised a new form of biometric identification that relies on humans' ability to see flashes of light containing just a handful of photons. [22] A research team led by Professor CheolGi Kim has developed a biosensor platform using magnetic patterns resembling a spider web with detection capability 20 times faster than existing biosensors. [21] Researchers at Columbia University have made a significant step toward breaking the so-called "color barrier" of light microscopy for biological systems, allowing for much more comprehensive, system-wide labeling and imaging of a greater number of biomolecules in living cells and tissues than is currently attainable. [20] Scientists around the Nobel laureate Stefan Hell at the Max Planck Institute for Biophysical Chemistry in Göttingen have now achieved what was for a long time considered impossible – they have developed a new fluorescence microscope, called MINFLUX, allowing, for the first time, to optically separate molecules, which are only nanometers (one millionth of a millimeter) apart from each other. [19] Dipole orientation provides new dimension in super-resolution microscopy [18]
