Study: Are plug-ins the next wave of hybrid vehicles?

Is America ready for rechargeable cars? Teams of researchers at the University of Michigan and Pacific Northwest National Laboratory will explore this question and others with $2 million from the U.S. Department of Energy's offices of Electricity Delivery and Energy Reliability and Energy Efficiency & Renewable Energy.

Viewing dye-packed vesicles causes them to explode

It`s a long-standing question: Can just the act of observing an experiment affect the results? According to a new study by Rockefeller University scientists, if the experiment uses a fluorescent dye called acridine orange, the answer is a resounding “yes.”

Amazon Spins Up Digital Music Store

(AP) -- Web retailer Amazon.com Inc. launched its much-anticipated digital music store Tuesday with nearly 2.3 million songs, none of them protected against copying.

Clever plants chat over their own network

Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen reveals that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut off or eaten up. Many plants form internal communications networks and are able to exchange information efficiently.

EchoStar May Split Into 2 Companies

(AP) -- EchoStar Communications Corp. said Tuesday that it may split into two publicly traded companies, one to operate the Dish satellite TV service and the other to focus on technology development.

New use for stem cells found in war on terrorism

For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries. His most recent discovery, which produces billions of neural cells from a few stem cells, could now aid in national security.

Online game feeds music search engine project at UC San Diego

UC San Diego electrical engineers and computer scientists are working together on a computerized system that will make it easy for people who are not music experts (like the senior author`s mom) to find the kind of music they want to listen to - without knowing the names of artists or songs.

Qualcomm Raises 4Q Earnings Guidance

(AP) -- Qualcomm Inc. on Tuesday raised its profit forecast for the fourth quarter, citing higher-than-expected shipments of its chip sets for more advanced cellular phones.

Research warns that human papillomavirus might cause bladder cancer

The Human Papillomavirus (HPV) is considered the cause of one of the most important sexually transmitted diseases nowadays, and affects both men and women. HPV is so common in our society that only people who have never had sexual relations can be sure that they have not been exposed to this disease. However, as with other microbes, people infected do not necessarily develop the disease, because,...

Researchers set new record for brightness of quantum dots

By placing quantum dots on a specially designed photonic crystal, researchers at the University of Illinois have demonstrated enhanced fluorescence intensity by a factor of up to 108. Potential applications include high-brightness light-emitting diodes, optical switches and personalized, high-sensitivity biosensors.

Study shows how the zebrafish gets his stripe

Scientists have discovered how the zebrafish (Danio rerio) develops one of its four stripes. Their findings add to the growing list of tasks carried out by an important molecule that is involved in the arrangement of everything from nerve cells to reproductive cells in the developing embryo.

YES2 student payload released from Foton-M3

The Second Young Engineers` Satellite (YES2) was activated and separated from the Foton-M3 spacecraft earlier today. The tether deployed for 8.5 km, after which the Fotino capsule was released on its way to Earth.

Splitting Water with Sunlight

Hydrogen is one of the most important fuels of the future, and the sun will be one of our most important sources of energy. Why not combine the two to produce hydrogen directly from solar energy without any detours involving electrical current? Why not use a process similar to the photosynthesis used by plants to convert sunlight directly into chemical energy?

'Arnie,' 'Al' Push Climate Action

(AP) -- "Arnie" and "Al," Republican and Democrat, shared the world spotlight to press for climate action, adding a touch of star quality to the staid proceedings of a U.N. summit.

A new look at the proton

Dutch researcher Paul van der Nat investigated more than three million collisions between electrons and protons. In his PhD thesis he demonstrates -- for the first time -- that the spin contribution of quarks to the proton can be studied by examining collisions in which two particles (hadrons) are produced.

Asian spacefarers race for the moon

Asian giants Japan, China and India are engaged in a race to map lunar resources and make the moon a platform to explore planets beyond, amid a renewed burst of global space activity.

Baby booms and birth control in space

Stars in galaxies are a bit similar to people: during the first phase of their existence they grow rapidly, after which a stellar birth control occurs in most galaxies. Thanks to new observations from Dutch astronomer Mariska Kriek with the Gemini Telescope on Hawaii and the Very Large Telescope in Chile, it is now known that a part of the heavy galaxies already stopped forming stars when the...

Bavaria to build Maglev train line in Germany

Bavarian officials have found funds to build a magnetic levitation train with the backing of industrial groups, but more than half the region's residents oppose the futuristic and already fatal project.

Chinese takeaway in the Wadden Sea

Shore crabs catch their food at food-rich spots and subsequently eat it elsewhere. With this takeaway strategy the crabs maximize their food uptake and keep competing crabs at a distance, says Dutch researcher Isabel Smallegange.
