Bad weather is bad news for any ship. High-speed craft, able to skim open seas at 35 knots or more, are particularly vulnerable in strong winds. But captains may soon base their sail decisions on real-time information, generated by sophisticated new on-board equipment.
Some 300 high-speed vessels today criss-cross busy European sea routes. Though popular with passengers, they are more prone to cancellation than traditional ships when the weather turns nasty. According to Marielle Labrosse of French engineering company Mettle and coordinator of the IST project Wings-for-Ships, "Unwelcome weather adversely affects around 8 per cent of crossings by these ships. That is when those responsible for making the decision to go or not must think very carefully."
Fast vessels are most efficient and profitable travelling at top speed in calm waters. So if bad weather leads to their cancellation or forces them to slow down or return to port, they become a liability for their owners.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
