Amazon Spins Up Digital Music Store
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.
Biologists link Huntington's disease to health benefits in young
(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.
City birds better than rural species in coping with human disruption
For years researchers in neurology have believed that people with Huntington`s disease have more children than the general population because of behavioral changes associated with the disease that lead to sexual promiscuity.
Clever plants chat over their own network
Birds that hang out in large urban areas seem to have a marked advantage over their rural cousins - they are adaptable enough to survive in a much larger range of conditions.
Cystic fibrosis patients may breathe easier, thanks to bioengineered antimicrobials
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
By better understanding how antimicrobials bind and thereby get inactivated in the mucus of air passages, researchers at the University of Illinois may have found a way to help cystic fibrosis patients fight off deadly infections.
Molecular profiling can accurately predict survival in colon cancer patients
(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
Researchers in The Netherlands have developed a method of accurately predicting which patients with colon cancer are most likely to have their disease recur after surgery and who would, therefore, be likely to benefit from additional chemotherapy.
Nosespray vaccine using aloe vera has exciting potential, researcher says
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
Researchers at Texas A&M University are participating in developing a medicine that is worth sneezing about: a treatment for influenza that forms a jelly when sprayed into the nose.
Qualcomm Raises 4Q Earnings Guidance
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.
Research warns that human papillomavirus might cause bladder cancer
(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.
Researchers set new record for brightness of quantum dots
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,...
Study shows how the zebrafish gets his stripe
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.
YES2 student payload released from Foton-M3
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.
Splitting Water with Sunlight
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.
'Arnie,' 'Al' Push Climate Action
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?
A new look at the proton
(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.
Asian spacefarers race for the moon
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.
Baby booms and birth control in space
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.
Bavaria to build Maglev train line in Germany
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...
Chinese takeaway in the Wadden Sea
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.
How adhesive protein causes malaria
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.
Microsoft mulls investment in Facebook: Wall Street Journal
Researchers at the Swedish medical university Karolinska Institutet (KI) and the Swedish Institute for Infectious Disease Control (SMI) have identified the biochemical mechanism behind the adhesive protein that give rise to particularly serious malaria in children. The knowledge of how the malaria parasite makes blood vessels become sticky paves the way for a future vaccine for the disease, which...
Microsoft is mulling an investment of up to 5.0 percent in the social networking site Facebook, a move that could set the stage for confrontation with rival Google, the Wall Street Journal reported.
