Levels of biomarkers in the cerebrospinal fluid of individuals with very mild dementia may be associated with the rate at which their thinking, learning and memory skills decline, according to a report in the May issue of Archives of Neurology.

"Audience segmentation" refers to categorizing people by their behaviors, attitudes, opinions, or lifestyles. It is widely used in social-marketing efforts. A new study uses this method to find high-risk drinkers in the US, leading researchers to a group dubbed the Cyber Millenials: "the nation's tech-savvy singles and couples living in fashionable neighborhoods on the urban fringe."

Dish Network Corp., the second-largest satellite TV provider in the U.S., surprised investors Monday by posting first-quarter results that were not as bad as feared. Earnings rose by 21 percent on the back of price increases and lower costs.

Regularly eating fish, nuts, olive oil and other foods containing omega-three fatty acids and avoiding trans fats appears to be associated with a lower risk for the eye disease age-related macular degeneration, according to two reports in the May issue of Archives of Ophthalmology.

A teenage skier from the Nepalese national team who went missing while training in the Alps has been found wandering the streets of Paris thanks to a Facebook campaign, his team said Monday.

Greece's data protection agency Monday barred Google from taking any more images on the nation's streets for its Street View feature, pending "additional information" from the US search engine service.

(PhysOrg.com) -- The Hubble community bids farewell to the soon-to-be decommissioned Wide Field and Planetary Camera 2 onboard NASA's Hubble Space Telescope. In tribute to Hubble's longest-running optical camera, which was developed and built by NASA's Jet Propulsion Laboratory, Pasadena, Calif., a planetary nebula has been imaged as the camera's final "pretty picture."

(PhysOrg.com) -- If you were to snorkel just before dawn at the popular tropical Pacific destination Jellyfish Lake, you'd have lots of company: millions of golden jellyfish, known to scientists as Mastigias papua, mill around the western half of the lake, waiting for sunrise.

(PhysOrg.com) -- Like tiny Jedi knights, tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also provide imaging in medical devices, eliminating the necessity and discomfort of moving the tip of a probe.

Shake things up with MOTO W7 Active Edition, a motion-enabled 3G mobile device announced today by Motorola. Designed for those who want a "moving" phone experience, MOTO W7 is equipped with an accelerometer that senses your body`s motions, orientation and hand gestures to perform tasks.

(AP) -- President Barack Obama on Monday portrayed the health care industry's promise to cut $2 trillion in costs over 10 years as "a watershed event" in the long search for a solution to the millions of uninsured.

The responses of older adults who are asked whether they had a stroke frequently do not agree with diagnoses obtained by magnetic resonance imaging (MRI) of the brain, according to a report posted online today that will appear in the July print issue of Archives of Neurology.

(PhysOrg.com) -- A study by information systems researchers at the University of Arkansas shows that as many as three out of four college students may be illegally copying and downloading digital material, including copyright-protected music, movies and software.

Alcohol-use disorders (AUDs) can damage the brain, particularly the frontal and parietal cortices, although this damage is at least partially reversible with sustained abstinence from alcohol. Chronic smoking is extremely common among individuals with AUDs. A new study has used longitudinal magnetic resonance imaging (MRI) of brain blood flow to show that smoking makes it harder for brain blood...

Iron chelating drugs have been heavily promoted for use in patients with primary myelofibrosis (PMF), a form of blood cancer often treated with blood transfusion. These drugs, however, which withhold available iron in the body, are highly expensive and potentially toxic. A new study published in American Journal of Hematology finds that their increased use has been propagated by non-evidence...

The discovery of tumor-suppressor genes has been key to unlocking the molecular and cellular mechanisms leading to uncontrolled cell proliferation - the hallmark of cancer. Often, these genes will work in concert with others in a complex biochemical system that keeps our cells growing and dividing, disease free.

Two Oregon State University researchers have uncovered a pattern of distrust - and sometimes outright antagonism - among physicians at hospitals and midwives who are transporting their home-birth clients to the hospital because of complications.

Early findings about the emerging pandemic of a new strain of influenza A (H1N1) in Mexico are published today in Science.

(PhysOrg.com) -- First motion is almost always a big event in the world of space exploration. Whether the first motion is of a wheel beginning to rotate or a rocket lifting off the pad, first motion means things are definitely changing. On day four of the upcoming shuttle servicing mission of the Hubble Space Telescope, there will be another such significant first motion. It will begin when a bolt...
