A variety of strange vehicles including the German Ball Tank (Yes, a tank shaped like a ball) and the proposed walking tank (think scout walker), both shown above.
Israeli researchers propose seeding roads with peizoelectric crystals. They expect that a 1-km stretch of 4-lane highway could generate 400 kilowatts of energy. The plan to begin testing on a 100 metre stretch of highway in January.
Princeton researchers believe they have observed the last of three criteria for addiction related to sugar intake. Previously they had observed that sugar consumption in mice demonstrates a behavioural pattern of increased uptake and signs of withdrawal, but the missing element was craving and relapse.
An aircraft-mounted laser was test-fired, albeit from a stationary plane. The ABL is the result of a 12-year, $4.3 billion(US) project to put a high-energy weapon in the sky. In theory, a megawatt laser should be capable to causing the pressurized parts of a missile to warp, resulting in it's disintegration.
The WhiteKnightTwo mothership is designed to carry the SpaceShipTwo aloft. When the combo achieves sufficient altitude, SpaceShipTwo detaches and heads for suborbital space, all for $200,000(US) from each of it's six passengers.
The presence of large quantities of carbonates, which don't form in conditions hostile to life, indicate that Mars was once benign enough to support life. The green areas in the image are areas that contain carbonates. Much of the Martain surface was also once covered with salt-rich (acidic) water, but carbonates dissolve quickly in acids so extensive areas must have been far less salty, raising the possibility that such areas could have supported life.
A UK academic has suggested four classifications for habitable worlds. Class 1 is Earth-like and acts as a baseline. Class II are Mars-like planets that were formerly habitable like Mars and Venus. Class III are Europa-like ice worlds with liquid oceans. Class IV are worlds composed almost entirely of liquid water.
A CBC documentary which postulates that the increase in male reproductive problems are chemicals found in everything from shampoo to sunglasses. I haven't seen it yet so I can't comment as to whether this is more sensation or scientific reporting.
National Geographic holds weekly photography contests in categories of People, Places, and Nature. They also have online jigsaw puzzles for those so inclined.
