When a magnet is heated up, it reaches a critical point where it loses magnetization. Called "criticality," this point of high complexity is reached when a physical object is transitioning smoothly from one phase into the next.
National University of Singapore (NUS) physicists have developed a computational imaging technique to extract three-dimensional (3D) information from a single two-dimensional (2D) electron micrograph. This method can be readily implemented in most transmission electron microscopes (TEMs), rendering it a viable tool for rapidly imaging large areas at a nano-scale 3D resolution (approximately 10 nm).
Insight into effects of femtosecond pulses on zebrafish larvae points to enhanced microscopy methods.
Nonlinear light microscopy has revolutionized our ability to observe and understand complex biological processes. However, light can also damage living matter. Yet, the mechanism behind the irreversible perturbation of cellular processes by intense light remains poorly understood.
<p>Scientists at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and their international collaborators have recently developed a new method for efficiently extracting information from galaxy surveys.</p>
