As an eleven year old boy in 1985, Donald Wylie tossed a bottle into the Orkney sea, with a message asking its finder to track him down. Almost a quarter of a century later, Donald will be reunited with the bottle which eventually washed up hundreds of miles away on the West Sands in St Andrews

Ship-in-a-bottle kit on a microchip
(PhysOrg.com) -- Sometimes physicists resort to tried and trusted model-making tricks. Scientists at the Max Planck Institute for Metals Research, the University of Stuttgart and the Colorado School of Mines have constructed micromachines using the same trick that model makers use to get ships into a bottle where the masts and rigging of the sailing ship are not erected until it is in the bottle. In the same way, the scientists link the valves, pumps and stirrers of a microlaboratory to create a micro device on a chip. To do this, they introduce colloidal particles - tiny magnetizable plastic spheres - as components into the channels on the chip. A rotating magnetic field is used to link the components into larger aggregates and set them into motion as micromachines. (

(PhysOrg.com) -- Flames shot more than 100 feet high in a successful 5.5-second ground test firing Thursday, Nov. 20, of a launch abort motor for NASA's next generation spacecraft, the Orion crew exploration vehicle. NASA and the Orion industry team conducted the firing at the Alliant Techsystems, or ATK, facility in Promontory, Utah.
Hazardous alternatives to alcohol beverages are still widely available in Russia
The term "non-beverage alcohols" refers to manufactured liquids that contain alcohol but are not intended for consumption, such as medicinal tinctures, aftershave, alcohol-based anti-freeze, antiseptics, and eau-de-colognes. Drinking these products is very hazardous to one's health. Prior research (see the October 2005 issue of
Alcoholism: Clinical & Experimental Research) had found a high availability of non-beverage alcohols in one city in Russia; this follow-up study of 17 Russian cities has found they are still widely available.
