UF study: Isthmus of Panama formed as result of plate tectonics
Contrary to previous evidence, a new University of Florida study shows the Isthmus of Panama was most likely formed by a Central American Peninsula colliding slowly with the South American continent through tectonic plate movement over millions of years. view more (2008-07-30)
Wii Fit a promising tool for all ages
While some emerging technologies can create environments that require very little physical effort, one Kansas State University researcher thinks games like Nintendo's Wii Fit can help promote physical rather than sedentary activities for people of all ages. view more (2009-01-07)
Eye movement tasks can be used to assess fetal alcohol spectrum disorders
Fetal alcohol spectrum disorders (FASD) refers to a wide array of adverse developmental outcomes in children due to prenatal alcohol exposure. view more (2007-02-23)
Amphetamines reverse Parkinson's disease symptoms in mice
Amphetamines, including the drug popularly known as Ecstasy, can reverse the symptoms of Parkinson's disease in mice with an acute form of the condition, according to new research at Duke University Medical Center. view more (2005-08-02)
On the track of tiny larvae, a new model elucidates connections in marine ecology
A computer model newly developed by researchers combines ocean current simulations and genetic forecasting to help scientists predict animal dispersion patterns and details of the ecology of coral reefs across the Caribbean Sea. view more (2006-08-22)
Abnormal Brain Circuits May Prevent Movement Disorder
Most people who carry a genetic mutation for a movement disorder called dystonia will never develop symptoms, a phenomenon that has puzzled scientists since the first genetic mutation was identified in the 1990's. view more (2009-08-06)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
Penn physicists track the random walks of ellipsoids, test 'lost' theory of Brownian motion
Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ago when he first described rotational Brownian motion for spheres in water. view more (2006-10-27)
New Guidelines Improve Diagnosis and Quality of Life for People with Parkinson Disease
New guidelines developed by the American Academy of Neurology aim to educate physicians on the diagnosis and treatment of Parkinson disease and provide people with Parkinson disease an improved quality of life. view more (2006-04-03)
Insight into dopamine role suggests new treatment pathway for Parkinson's
Dopamine (DA) not only functions as a neurotransmitter, a chemical messenger between neurons by which one neuron triggers another, researchers have found. view more (2006-10-19)
New procedure allows diagnosis of lower back pain cause
Functional anesthetic discography (FAD), a new diagnostic procedure involving injecting anesthetic directly into a spinal disc, can be used to confirm the presence of injured discs as the source of a patient's lower back pain symptoms. view more (2007-05-07)
National Open Access agreement for Finland
Finland is the first country to make a nationwide commitment to Open Access, it was announced today. All universities, polytechnics and research institutes in Finland have become BioMed Central members. The membership agreement covers the cost of publication, in BioMed Central's 100+ Open Access journals, for all 25000 publicly funded researchers... view more... (2004-05-10)
Newly discovered active fault building new Dalmatian Islands off Croatian coast
A newly identified fault that runs under the Adriatic Sea is actively building more of the famously beautiful Dalmatian Islands and Dinaride Mountains of Croatia, according to a new research report. view more (2008-01-23)
Ancient glaciers still affect the shape of North America, say scientists
Long after the disappearance of the glaciers that once covered much of North America, the land they rested upon is still recovering from their weight - and the slow movement of this recovery includes horizontal motion never seen before. view more (2005-12-15)
Caltech scientists find cells coordinate gene activity with FM bursts
How a cell achieves the coordinated control of a number of genes at the same time, a process that's necessary for it to regulate its own behavior and development, has long puzzled scientists. view more (2008-10-01)
JHU chemists devise self-assembling 'organic wires'
From pacemakers constructed of materials that so closely mimic human tissues that a patient's body can't discern the difference to devices that bypass injured spinal cords to restore movement to paralyzed limbs, the possibilities presented by organic electronics read like something from a science fiction novel. view more (2008-10-24)
Like a snail through the intestinal canal
The medical device currently used for intestinal research, the colonsope, causes patients great discomfort. At TU Delft, an alternative method has been developed, inspired by the way in which snails move. view more (2006-09-22)
3D Sound Systems Using Groundbreaking Piezoelectric Springs
Piezoelectric materials such as quartz are used in digital watches and computers to produce stable vibrations at high frequencies. Polycrystaline ceramics, such as PZT (lead zirconate titanate), can be made to mimic the behaviour of these natural monocrystaline materials by polarising the crystals within the ceramic. This is done by applying an... view more... (1999-11-29)
Researchers find differences in swallowing mechanism of Rett syndrome patients
Researchers at Wake Forest University Baptist Medical Center have found that the reflux and swallowing problems that are common symptoms in patients with Rett syndrome and other neurological impairments, may be caused by a different mechanism than they are in healthy individuals. view more (2008-08-05)
Resilin springs simplify the control of crustacean limb movements
Animals can simplify the brain control of their limb movements by moving a joint with just one muscle that operates against a spring made of the almost perfect elastic substance called resilin. view more (2009-05-29)
