Nanotube Water Doesn't Freeze -- Even At Hundreds Of Degrees Below Zer
A new form of water has been discovered by physicists in Argonne's Intense Pulsed Neutron Source (IPNS) Division. Called nanotube water, these molecules contain two hydrogen atoms and one oxygen atom but do not turn into ice -- even at temperatures near absolute zero. Hackers Supersize Zune Hard Drive
A relatively easy hardware mod gives Microsoft's music player an enormous upgrade. In Gear Factor. Amazon Mechanical Turk: Artificial Artificial Intelligence
This online service allows computer software designers to pose "Human Intelligence Tasks"(HITs) for people to answer. Those who answer are paid a nominal fee, and the designers incorporate the answers into their programs. Includes a FAQ and list of HITs. (The name for the service is based on an 18th century hoax in which a "mechanical chess-playing automaton"beat almost all opponents.) From Amazon.com. Safe journey for works of art
Valuable paintings travel long distances when they are shipped from one place to another. To minimize damage, they are packed in special picture cases. In future, these will be equipped with sensors to detect the buildup of pollutant gases, emanating from adhesives for example. Ebola Virus: From Wildlife To Dogs
Since 1976 the Ebola virus has caused some lethal human epidemics in Central Africa. Research now indicates that humans do not become directly contaminated from the animal reservoir, which is an any case still unknown, but from infected carcasses of chimpanzees, gorillas and certain forest antelopes. Results have come from work conducted over the past several years by IRD scientists and their partners to shed light on the virus's propagation paths.

Two substances that occur naturally in the brain act to protect the brain during a stroke. This is the conclusion of a dissertation published at the Sahlgrenska Academy, and the discovery may lead to new treatmentsfor stroke patients. Stroke is the result of an infarction, or bleeding, within the brain, and it may lead to impaired movement, impaired sensation, and difficulties in cognitive function and speech. Approximately 30,000 people are affected by stroke each year in Sweden, and it is the most common cause of long-term dependence on care. Blogging + Video = Vlogging

Cells in an embryo divide at an amazing rate to build a whole body, but this growth needs to be controlled. Controlling growth requires that some cells divide while others die; their fates are determined by signals that are passed from molecule to molecule within the cell. Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg have now discovered how one of these signaling pathways controls the life and death of cells in the fruit fly.
