| Subliminal Learning Demonstrated In Human Brain Thu, 28 Aug 2008 14:00:00 EDT |
Although the idea that instrumental learning can occur subconsciously has been around for nearly a century, it had not been unequivocally demonstrated. Now, new research uses sophisticated perceptual masking, computational modeling, and neuroimaging to show that instrumental learning can occur in the human brain without conscious processing of contextual cues. |
| High Cholesterol Levels Drop Naturally In Children On High-fat Anti-seizure Diet, Study Show Thu, 28 Aug 2008 14:00:00 EDT |
Elevated cholesterol levels return to normal or near normal levels over time in four out of 10 children with uncontrollable epilepsy treated with the high-fat ketogenic diet, according to results reported in the Journal of Child Neurology. |
| Olive Leaf Extract Can Help Tackle High Blood Pressure And Cholesterol Thu, 28 Aug 2008 14:00:00 EDT |
Taking 1000 mg of a specific olive leaf extract (EFLA 943) can lower cholesterol and lower blood pressure in patients with mild hypertension (high blood pressure). These findings came from a "Twins" trial, in which different treatments were given to identical twins. By doing this, researchers could increase the power of their data by eliminating some of the uncertainties caused by genetic variations between individual people. |
| Army Personnel Show Increased Risk For Migraine; Condition Underdiagnosed, Mistreated Thu, 28 Aug 2008 14:00:00 EDT |
Two new studies show that migraine headaches are very common among US military personnel, yet the condition is frequently underdiagnosed. The studies, appearing in Headache, the peer-reviewed journal of the American Headache Society, examine the incidence among soldiers within 10 days of returning from a 1-year combat tour in Iraq , as well as US Army officer trainees. |
| Facades: A Source Of Water Pollution Thu, 28 Aug 2008 14:00:00 EDT |
For many years, fingers have been pointed at agriculture whenever pesticides are detected in rivers and streams. Studies now show that built-up areas also account for a considerable proportion of such inputs. For example, substances can be leached out of facade renders and paints by rainwater and enter the environment, where they may have toxic effects on organisms. |
| Teens Making Poor Choices When It Comes To Riding In Vehicles Thu, 28 Aug 2008 14:00:00 EDT |
Car crashes are the No. 1 killer of US teens. While states are passing laws to help teen drivers, little thought is being given to their habits as passengers. A new study uncovers a public health crisis and offers a solution to the problem. |
| Jamaican Lizards' Shows Of Strength Mark Territory At Dawn, Dusk Thu, 28 Aug 2008 11:00:00 EDT |
What does Jack LaLanne have in common with a Jamaican lizard? Like the ageless fitness guru, the lizards greet each new day with vigorous push-ups. That's according to a new study showing that male Anolis lizards engage in impressive displays of reptilian strength -- push-ups, head bobs, and threatening extension of a colorful neck flap called a dewlap -- to defend their territory at dawn and dusk. |
| First Gene Associated With Dry Macular Degeneration Found Thu, 28 Aug 2008 11:00:00 EDT |
In a study that underscores the important role that individual genetic profiles will play in the development of new therapies for disease,scientists have made two important discoveries related to age-related macular degeneration, the leading cause of blindness in adults over the age of 60. |
| Wind-powered 'Ventomobile' Places First in Race Thu, 28 Aug 2008 11:00:00 EDT |
The solely wind-driven Ventomobile constructed by a team of students in aerospace engineering came in first at the Aeolus Race in the Dutch town of Den Helder last Friday. Racing the extremely stylish and lightweight three-wheeler, the vehicles of five European universities and research centres had difficulties to catch up. |
| New Concepts In Contraception Thu, 28 Aug 2008 11:00:00 EDT |
Latest research into dual-purpose contraceptives and non-hormonal contraception will be presented at a major scientific conference in Melbourne. |
| New LIDAR System Sees The Sky In 3D Thu, 28 Aug 2008 11:00:00 EDT |
A new LIDAR measurement system -- unique in the world -- will provide continuous data on atmospheric humidity for Western Switzerland's weather forecasting headquarters. |
| Unusual Ultrasonic Vocalization Patterns In Mice May Be Useful For Modeling Autism Thu, 28 Aug 2008 11:00:00 EDT |
Scientists have found novel patterns of ultrasonic vocalizations in a genetic mouse model of autism, adding a unique element to the available mouse behaviors that capture components of the human disease, and representing a new step towards identifying causes and better treatments. |
| Minimum Mass For Galaxies Discovered: Breakthrough Sheds Light On Mysterious Dark Matter Thu, 28 Aug 2008 08:00:00 EDT |
By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe -- 10 million times the mass of the sun. |
| Heart Attack Prevention: Potential New Use For Viagra? Thu, 28 Aug 2008 08:00:00 EDT |
A breakthrough into regulating a single enzyme may lead to new drug therapies that will help prevent heart attacks and strokes. The research focuses on the effects of Viagra -- the popular erectile dysfunction drug, which is also used to treat pulmonary hypertension. |
| Genetic Underpinnings Of Sheep Traits May Yield Clues To Greater Productivity Thu, 28 Aug 2008 08:00:00 EDT |
Keeping America's sheep healthy and productive while expanding the market for wool and lamb is the goal of scientists who are matching the animals' physical traits to the genes that underpin their expression. |
| More Aortic Chest Aneurysms Being Treated With Less-invasive Stents Thu, 28 Aug 2008 08:00:00 EDT |
An increasing number of patients with thoracic aortic aneurysms are being treated with a device called a stent graft, rather than open-chest surgery. The device is delivered with a cathether. Patients go home in a day or two. It's much less invasive than open-chest surgery. |
| Fingerprint Breakthrough Hope In US Double Murder Probe Thu, 28 Aug 2008 08:00:00 EDT |
A double murder investigation that has remained unsolved for almost a decade could be provided new impetus following a forensic breakthrough. |
| Over 10 Million Americans Are Taking Opioids Each Week, Study Finds Thu, 28 Aug 2008 08:00:00 EDT |
Researchers from Boston University's Slone Epidemiology Center have found that in a given week, over 10 million Americans are taking opioids, and more than 4 million are taking them regularly (at least five days per week, for at least four weeks). These findings appear in the Aug. 31 issue of the journal Pain. |
| Why Is Greenland Covered In Ice? Changes In Carbon Dioxide Levels Explain Transition Thu, 28 Aug 2008 05:00:00 EDT |
A fall in levels of atmospheric carbon dioxide, close to that of pre-industrial times, explains the transition from a mostly ice-free Greenland of three million years ago to the ice-covered region we see today. |
| Heart Attack Patients Who Stop Statin Risk Death, Say Researchers Thu, 28 Aug 2008 05:00:00 EDT |
Patients discontinuing statin medication following an acute myocardial infarction increase their risk of dying over the next year, say researchers at McGill University and the McGill University Health Center. Their study was published in a recent issue of the European Heart Journal. |
