Illuminating a biological light switch

Using an innovative new imaging technique, researchers at Weill Cornell Medicine have revealed the inner workings of a family of light-sensing molecules in unprecedented detail and speed. The work could inform new strategies ...

Light reveals the origin of a grain of sand

A grain of sand buried for an extended period of time in earthworks or on the bottom of the ocean, accumulate a luminescence signal. Scientists use this signal to determine how long a particular grain of sand has been buried. ...

Organic photodiodes for sensor applications

Powerful, inexpensive and even flexible when they need to be, organic photodiodes are a promising alternative to silicon-based photodetectors. They are used to improve light sensitivity in cameras and to check displays for ...

An ultrasensitive molybdenum-based image sensor

A new material has the potential to improve the sensitivity of photographic image sensors by a factor of five. In 2011, an EPFL team led by Andras Kis discovered the amazing semi-conducting properties of molybdenite (MoS2), ...

Scientists discover why soft corals have unique pulsating motion

Scientists from the Hebrew University of Jerusalem and the Technion-Israel Institute of Technology have discovered why Heteroxenia corals pulsate. Their work, which resolves an old scientific mystery, appears in the current ...
