Container ships become more energy-efficient

Technology and Software from Siemens are making the world's largest container ships more energy-efficient. The Korean shipbuilding company Daewoo is building 20 container ships for the Danish shipping company Maersk, each ...

Researchers design compact high-power laser using plasma optics

Lawrence Livermore National Laboratory (LLNL) researchers have designed a compact multi-petawatt laser that uses plasma transmission gratings to overcome the power limitations of conventional solid-state optical gratings. ...

A primary standard for measuring vacuum

A novel, quantum-based vacuum gauge system invented by researchers at the National Institute of Standards and Technology (NIST) has passed its first test to be a true primary standard—that is, intrinsically accurate without ...

New quantum system could help design better spintronics

Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics.

Studies add to concern about climate tipping

Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the ...

A new twist for quantum systems

Physicists at ETH Zurich have developed a method for precisely controlling quantum systems by exploiting a trick that helps cats to land on their feet and motorists to fit their cars into parking spots. In the longer run, ...
