Scientists funded by the Medical Research Council (MRC) have shown, for the first time, how our brain 'wiring' develops in the first few months of life. Using a new imaging technique, the scientists monitored the formation of insulating layers around nerve cells, a process called myelination, which is vital for normal brain function. Damage to the myelination process is believed to contribute to a...
A research team led by astronomers from the University of Tokyo and the National Astronomical Observatory of Japan (NAOJ) has discovered that inclined orbits may be typical rather than rare for exoplanetary systems -- those outside of our solar system. Their measurements of the angles between the axes of the star's rotation (stellar rotational axis) and the planet's orbit (planetary orbital axis)...
(AP) -- It looks like Rep. Gabrielle Giffords is one of the lucky ones. Few people who take a bullet to the brain - just 10 percent - survive such a devastating wound.
(AP) -- Shares of Merck & Co. are falling after the drugmaker says it has halted one late-stage trial of a potential blood thinner and will immediately stop giving the drug in another study to patients who have had a stroke.
NASA this week told Congress it cannot afford to build a new heavy-lift rocket and spacecraft to replace the retiring space shuttle program within the current budget approved by Congress.
Nootkatone, a component of essential oil in grapefruit peels and other sources, is used in many food, beverage and personal-care products because of its clean, citrusy taste and smell.
Plant biologists are facing pressure to quantify the response of plants to changing environments and to breed plants that can respond to such changes. One method of monitoring the response of plants to different environments is by studying their vein network patterns. These networks impact whole plant photosynthesis and the mechanical properties of leaves, and vary between species that have...
Advancements in understanding rotational motion in living cells may help researchers shed light on the causes of deadly diseases, such as Alzheimer's, according to Ning Fang, an associate scientist at the U.S. Department of Energy's Ames Laboratory and faculty member at Iowa State University.
News Corp. said Thursday it is exploring "strategic options" for Myspace amid reports it is considering a sale, merger or spinoff of the ailing social network.
For the first time in history, the next generation will not live longer than their parents.
The discovery of a hot Jupiter exoplanet that transfers orbital momentum to its host star may hold the key to a clearer understanding of the evolution of common planetary systems, according to findings presented by Dr. Edward Guinan, a professor of astronomy at Villanova University in Villanova, Pa.
The first baby boomers will turn 65 in 2011, but is this generation truly ready to leave the workforce?
Ratting on neighbours who light up on the sly can be lucrative in Sweden, where a landlords' association said Thursday it would offer a hefty reward for shopping people who violate a strict smoking ban in a residential building.
Twenty years of mortality data from counties across the United States led to the striking discovery that living at higher altitudes may be a risk factor for suicide, according to a provocative study published online ahead of print in High Altitude Medicine & Biology.
A European Internet study has an instant message for parents who want to control their children's online habits: web filters are not 100 percent foolproof against harmful sites.
Biologists have been unable to agree on a definition of the complex phenomenon known as "life." In a special collection of essays in Astrobiology, a peer-reviewed journal from Mary Ann Liebert, Inc., leaders in the fields of philosophy, science, and molecular evolution present a variety of perspectives on defining life. Tables of content and a free sample issue are available online.
One of the world's rarest wild cats, an elusive creature once thought to be extinct, has been spotted in camera traps in Malaysian Borneo for the first time since 2003, researchers said Thursday.
Men are more likely than women to seek jobs in which competition with coworkers affects pay rates, a preference that might help explain persistent pay differences between men and women, a study at the University of Chicago shows.
Researchers from the Kimmel Cancer Center at Jefferson and two other institutions have discovered new evidence that suggests the "longevity" protein SIRT1, known for its life-spanning effects in different species, can inhibit the development of a known precursor to prostate cancer, prostatic intraepithelial neoplasia (PIN).
Surviving cancer may also mean surviving pain, according to a study by the University of Michigan Health System showing 20 percent of cancer survivors at least two years post diagnosis have current cancer-related chronic pain.
The inhibition or removal of an enzyme may prevent or treat ischemic retinopathy by stalling growth of unwanted vessels in the retina, Medical College of Georgia researchers say.
Two federal agencies announced on January 7 that they are exploring new guidelines for water fluoridation and with good reason, according to the American Dental Association (ADA).
In their paper, Exploring the impacts of accelerated delivery on student learning, achievement and satisfaction, published in Research in Post-Compulsory Education, Stephen Wilkins, from the International Center of Higher Education Management, Dr. Susan Martin, from the Department of Education, along with Dr. Ian Walker, from the Department of Psychology, suggest that many high ability...
Zoologists of the University Jena (Germany) analysed the central factor for the development of the morphologically distinctive features of the tadpoles. "We were able to show that the 'FOXN3' most of all influences the development of the cartilages in the oral region and the gills," professor Dr. Lennart Olsson points out. These structures in particular belong to the evolutionary new developments...
