Catching fast changes in excited molecules

It's hard to see certain molecules react. The reaction is just that fast. Until now. A team of scientists devised a way to reveal time- and energy-resolved information on "dark" states of molecules—ones that are normally ...

Scientists create anti-laser for a condensate of ultracold atoms

An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists have demonstrated that it is possible to absorb the selected ...

Study unravels long-held Fermi puzzle tied to nonlinear systems

In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem—which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states—has been a challenge that scientists have ...

Predicting the extent of flash flooding

Devastating floodwaters such as those experienced during Iowa's Flood of 2008—which swamped many Iowa communities, along with ten square miles of Cedar Rapids—are notoriously difficult to predict.

Neuron circuit may enable pitch perception applications

The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit operates according ...

2012 Great Plains drought not caused by climate change

From May to July 2012, the Great Plains region of the western United States faced a powerful and unpredicted drought. Following 7 months of normal rainfall, the drought was one of the largest deviations from seasonal precipitation ...

Founder of US-based Bose audio firm dies at 83

Acoustics pioneer Amar Bose, founder and chairman of the audio technology company Bose Corp., known for the rich sound of its small tabletop radios and its noise-canceling headphones popular among frequent fliers, has died ...

Random noise helps make signals clearer

Scientists have shown the energy conditions, under which a weak signal supplied to a physical system emerges as a stronger signal at the output thanks to the presence of random noise (a process known as stochastic resonance), ...
