Insulator becomes conductor at the push of a button

Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Physicists from Leiden University have now found that the charging process of ionic liquids depends purely on opposite ...

Fish's use of electricity might shed light on human illnesses

Deep in the night in muddy African rivers, a fish uses electrical charges to sense the world around it and communicate with other members of its species. Signaling in electrical spurts that last only a few tenths of a thousandth ...

Detecting the shape of laser pulses

A team of researchers at the Center for Relativistic Laser Science, within the Institute for Basic Science (IBS) have developed a method to measure the shape of laser pulses in ambient air. Unlike conventional strategies, ...

Innovative microscope poised to propel optogenetics studies

A newly developed microscope is providing scientists with a greatly enhanced tool to study how neurological disorders such as epilepsy and Alzheimer's disease affect neuron communication. The microscope is optimized to perform ...

Electrons at the speed limit

Electronic components have become faster and faster over the years, thus making powerful computers and other technologies possible. Researchers at ETH Zurich have now investigated how fast electrons can ultimately be controlled ...

Electric eels make leaping attacks

In a legendary account the famous 19th century explorer and naturalist Alexander von Humboldt recounted a dramatic battle between horses and electric eels that he witnessed on a field trip to the Amazon. In the following ...
