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.

Building confidence in hydrologic models

Understanding water availability and quality for large-scale surface and groundwater systems requires simulation. Scientists have developed many numerical models to address these simulation needs. How do these models differ ...

Researchers offer new information warfare model

Researchers have collaborated to develop a mathematical model of information warfare in a society under periodic destabilization. The authors of the paper, which was published in Mathematical Models and Computer Simulations, ...

The return of the comet-like exoplanet

Astronomers from the University of Geneva (UNIGE), Switzerland and collaborators used the Hubble Space Telescope to study an exoplanet that had been observed losing its atmosphere, forming an enormous cloud of hydrogen and ...
