Lasers make magnets behave like fluids

For years, researchers have pursued a strange phenomenon: When you hit an ultra-thin magnet with a laser, it suddenly de-magnetizes. Imagine the magnet on your refrigerator falling off.

New method enables quantum simulations on larger systems

Through randomly selected measurements, Austrian physicists can now determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger number of quantum ...

Making a fast ion transporter

An international team of researchers at Institute for Molecular Science in Japan and Max Planck Institute of Biophysics in Germany has revealed an ion transport mechanism of sodium/proton antiporter by simulating its motion. ...

Could computer games help farmers adapt to climate change?

Researchers from Sweden and Finland have developed the interactive web-based Maladaptation Game, which can be used to better understand how Nordic farmers make decisions regarding environmental changes and how they negotiate ...

Bacterial mix helps predict future change

A controlled, laboratory approach, along with computer simulations, has helped KAUST researchers to show that bacterial communities can homogenously disperse within aquatic ecosystems, even with slow-flowing water and the ...

In preparation for his Beyond mission, ESA astronaut Luca Parmitano was at the Johnson Space Center in Houston, USA, in March 2019. Here he is strapped to the Partial Gravity Simulator to practice repairing the dark-matter ...

SLAC's high-speed 'electron camera' films molecular movie in HD

With an extremely fast "electron camera" at the Department of Energy's SLAC National Accelerator Laboratory, researchers have made the first high-definition "movie" of ring-shaped molecules breaking open in response to light. ...

Can we cure cancer by finding out how two proteins interact?

In a paper published in the Journal of Biological Chemistry, Dr. Özdemir has studied two protein families named Rho GTPases and IQGAPs, which are known to play an important role in cancer metastasis. These two "suspicious" ...

Quantum simulation more stable than expected

Simulation

Simulation is the imitation of some real thing, state of affairs, or process. The act of simulating something generally entails representing certain key characteristics or behaviours of a selected physical or abstract system.

Simulation is used in many contexts, including the modeling of natural systems or human systems in order to gain insight into their functioning. Other contexts include simulation of technology for performance optimization, safety engineering, testing, training and education. Simulation can be used to show the eventual real effects of alternative conditions and courses of action.

Key issues in simulation include acquisition of valid source information about the relevent selection of key characteristics and behaviours, the use of simplifying approximations and assumptions within the simulation, and fidelity and validity of the simulation outcomes.
