Famed '$100 Laptop' Now $188

(AP) -- The vaunted "$100 laptop" that Massachusetts Institute of Technology researchers dreamed up for international schoolchildren is becoming a slightly more distant concept.

Germany approves plan for TV on phones

German anti-monopoly authorities on Friday approved plans by mobile phone operators T-Mobile, O2 and Vodafone to create a joint technical platform to bring television to mobile phones.

Why is the Hercules Dwarf Galaxy so flat?

Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, an international team of astronomers has found that a recently discovered tiny companion galaxy to our Milky Way, named the Hercules Dwarf Galaxy, has truly exceptional properties: while basically all of its known peers in the realm of these tiny dwarf galaxies are rather round,...

'Radio Wave Cooling' Offers New Twist on Laser Cooling

Visible and ultraviolet laser light has been used for years to cool trapped atoms—and more recently larger objects—by reducing the extent of their thermal motion. Now, applying a different form of radiation for a similar purpose, physicists at the National Institute of Standards and Technology have used radio waves to dampen the motion of a miniature mechanical oscillator containing more than a...

Researchers test old drug with new hopes for pre-eclampsia cure

Researchers at the University of Texas Medical Branch at Galveston are trying to determine whether a drug already available to heart patients can also be used to delay delivery in expectant mothers with severe preeclampsia. If so, this groundbreaking study would give hope to hundreds of thousands of women who experience this life-threatening disorder each year.

Team develops novel method for nanostructured polymer thin films

All researchers at the National Institute of Standards and Technology wanted was a simple, quick method for making thin films of block copolymers or BCPs (chemically distinct polymers linked together) in order to have decent samples for taking measurements important to the microelectronics industry. What they got for their efforts, as detailed in the Sept. 12, 2007, Nano Letters, was an unexpected...

'Guide to Secure Web Services' provides blueprint to safer Web 2.0

Many Web-based services, from shopping to online word processing, allow computer programs to talk to each other and exchange user data across several Web sites without human intervention. Many of the attractive features of this “Web 2.0,” including greater access to information and one-stop transactions that process information from several websites, are at odds with traditional ways of...

Probing a rare material spin state

A team of international physicists that includes researchers from the National Institute of Standards and Technology has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials. Their work, one of the very few studies of this particular spin state, which has been postulated as a possible underlying mechanism for...

The missing link in the evolution of magnetic cataclysmic stars?

An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma. They found that the Paloma system has a weird way of rotating that fills the gap between two classes of magnetic cataclysmic stars. Their results will soon be published in Astronomy...

Lift-off for Foton microgravity mission

An unmanned Foton spacecraft, carrying a payload of more than 40 ESA experiments, was successfully launched earlier today. The Soyuz-U launcher lifted off from Baikonur Cosmodrome, Kazakhstan, at 13:00 CEST (11:00 GMT).

Satellites witness lowest Arctic ice coverage in history

The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage - a long-sought short cut between Europe and Asia that has been historically impassable.

Mother's milk a gift that keeps on giving

Extensive medical research shows that mothers` milk satisfies babies` nutritional needs far better than any manufactured infant formula. It also protects babies against many common infectious diseases and certain inflammatory diseases, and probably helps lower the risk of a child later developing diabetes, lymphoma and some types of leukemia.

Galaxy 'hunting' made easy

Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits a first-class instrument, represents a major breakthrough in the field of galaxy 'hunting'.

Deaths Blamed on Improper Painkiller Use

(AP) -- The deaths of two patients prescribed a powerful painkiller as a headache treatment were among four fatalities linked to the recently approved drug, its manufacturer reported Thursday.

Researchers Track Lake Erie Algae Blooms

(AP) -- NASA scientists are teaming with researchers from the National Oceanic and Atmospheric Administration to monitor Lake Erie's harmful algae blooms, a move that could lead to early warnings for beachgoers and water departments.
