(AP) -- Google Inc. said Friday it had filed for European Union permission to take over online ad tracker DoubleClick, a $3.1 billion deal that already has stirred concern about the control it will give Google over Internet advertising.

New research in primates suggests that infants and children who carry a certain gene variant may be more vulnerable to the ill effects of fetal alcohol exposure.

Growth hormone and associated proteins could be responsible for promoting many types of cancer, including breast and prostate cancer, according to an Australian researcher.

Researchers at the University of North Carolina at Chapel Hill have patented a synthetic version of the drug heparin, called Recomparin, that is less complex chemically and should be easier to produce than previous forms.

Radiation oncologists and urologists at the Kimmel Cancer Center at Jefferson and Thomas Jefferson University Hospital in Philadelphia have begun using a real-time system to implant radiation-emitting seeds in prostate cancer patients. While the system, which is made by Nucletron, a technology company based in The Netherlands, is only being used for imaging and planning purposes so far, it...

Resistance to chemotherapy treatments can be the worst news a cancer patient ever receives. A pair of researchers at the University of Missouri-Columbia is working steadfastly to learn why some tumors eventually build a tolerance to the common chemotherapy drug cisplatin, in hopes of identifying the particular genes that can be manipulated to make treatment as effective as possible.

NASA's Mars Odyssey spacecraft has discovered entrances to seven possible caves on the slopes of a Martian volcano. The find is fueling interest in potential underground habitats and sparking searches for caverns elsewhere on the Red Planet.

NASA's Mars Reconnaissance Orbiter (MRO) is examining several features on Mars that address the role of water at different times in Martian history.

An invisible force so mysterious that it has yet to be understood by even the most eminent astronomers is being turned into music at a new Cambridge University exhibition.

As we age, our brains slowly shrink in volume and weight. This includes significant atrophy within the frontal lobes, the seat of executive functioning. Executive functions include planning, controlling, and inhibiting thought and behavior. In the aging population, an inability to inhibit unwanted thoughts and behavior causes several social behaviors and cognitions to go awry.

Growing and burning many biofuel crops may actually raise, rather than lower, greenhouse gas emissions. That`s the conclusion of a new study led by Nobel prize-winning chemist Paul Crutzen, best known for his work on the ozone layer.

Britain on Friday launched a campaign to help schools combat "cyber-bullying" of children and teachers using the Internet and mobile phones.

In science fiction movies, it happens all the time: A small device is briefly held against the skin of a sick crewmember and seconds later the monitor displays what ails him. This futuristic image could someday be real.

A University of Queensland biophysical chemist is working on new research which one day may slow down or switch off certain diseases.

“There are many applications for ultracold neutrons in fundamental physics,” Oliver Zimmer tells PhysOrg.com. “And we will find even more applications with a stronger source of ultracold neutrons.” Zimmer, a scientist at the Institut Laue Langevin in Grenoble, France, thinks that he and his colleagues may have found a way to tap a better source for ultracold neutrons by extracting them from...

Chinese, Africans and Indians may differ in what odors they find yummy, but they all perceive pleasantness in the same way, according to the findings of neurobiologists from the University of California, Berkeley, and the Weizmann Institute of Science in Rehovot, Israel.

The development of wind power promises much in terms of providing us with renewable energy for the future and wind turbines could be the most effective way to harness that power. Danish researchers now suggest that in order to assess the overall environmental impact of wind power, however, the finite lifespan of wind turbines and the need to replace and recycle them must be taken into account....

Recently, researchers at Iowa State University discovered a way to increase the accuracy of a popular crop model. By zeroing in on early stages leading up to kernel formation, scientists believe they can help improve yield predictions across a variety of environmental conditions. The team of scientists reported their findings in the September-October issue of Crop Science.

Chinese scientists said Friday they had found fossils belonging to six baby dinosaurs that died in a volcanic mudflow 125 million years ago.

At least one case of cholera has been reported in Baghdad, raising concern that the epidemic in northern Iraq is spreading south.

A gorilla at the Brookfield Zoo in Illinois is the first gorilla to undergo uterine fibroid embolization.

A group of computer scientists, mathematicians, and biologists from around the world have developed a computer algorithm that can help trace the genetic ancestry of thousands of individuals in minutes, without any prior knowledge of their background. The team`s findings will be published in the September 2007 edition of the journal PLoS Genetics.

(AP) -- Palm Inc.'s death knell has been rung over and over - on Wall Street, in headlines, and by a growing number of discontented fans.

There is currently a great deal of interest in the health-associated properties of probiotics, also known as ‘beneficial` or ‘friendly` bacteria, and prebiotics, the food needed for the growth of probiotic when inside our bodies. University of Leicester scientists have discovered a natural fruit-based extract that dramatically improves the growth and probiotic qualities of ‘friendly` bacteria...
