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>

New developments herald a future of ultra-secure quantum communication.

Graphene's exceptional electron transport and mechanical properties make it a key material for advanced electronics and sensors.

An atomic force microscope operating in pendulum mode was utilized by SNI network researchers to examine a two-layer graphene device. The outcomes offer empirical evidence that the technique can be applied to adjust the device’s magnetization as well as current flow.

Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption developed at Linköping University, Sweden. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication. The study is published in the journal Communications Physics.

Back in 1867, in an effort to test his thoughts on the emerging science of thermodynamics, physicist James Clerk Maxwell imagined an intelligent 'demon' sorting molecules between two containers based on their energy.
