Record-shattering underwater sound

A team of researchers has produced a record-shattering underwater sound with an intensity that eclipses that of a rocket launch. The intensity was equivalent to directing the electrical power of an entire city onto a single ...

Pulsar punches hole in stellar disk

A fast-moving pulsar appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at a speed of about 4 million miles per hour. NASA's Chandra X-ray Observatory is ...

Data storage: Measuring the downside of downsizing

To keep pace with the rapidly growing consumer demand for data storage, hardware engineers are striving to cram as much electronic information into as small a space as possible. Jinmin Zhao, Mingsheng Zhang and co‐workers ...

Organic electronics—a hot matter

Organic semi-conductors could revolutionise electronics in various areas. Nowadays, components put out such high performances that they are used in small devices like mobile phones. With larger devices, however, the organic ...

DNA and quantum dots: All that glitters is not gold

(Phys.org)—A team of researchers at the National Institute of Standards and Technology (NIST) has shown that by bringing gold nanoparticles close to the dots and using a DNA template to control the distances, the intensity ...
