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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
