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.
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.
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.
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.
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.
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.
Latest research into dual-purpose contraceptives and non-hormonal contraception will be presented at a major scientific conference in Melbourne.
A new LIDAR measurement system -- unique in the world -- will provide continuous data on atmospheric humidity for Western Switzerland's weather forecasting headquarters.
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.
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.
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.
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.
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.
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.
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.
In experiments, sweet potatoes grown in Maryland and Alabama yielded two to three times as much carbohydrate for fuel ethanol production as field corn grown in those states, scientists report. The same was true of tropical cassava in Alabama.
Individuals with a history of nonmelanoma skin cancer are at increased risk for other cancers, according to a study published in the Aug. 26 online issue of the Journal of the National Cancer Institute.
A new bioinformatics tool is capable of identifying and correcting abnormal, incomplete and mispredicted protein annotations in public databases. The MisPred tool currently uses five principles to identify suspect proteins that are likely to be abnormal or mispredicted.
Scientists at the University of York have discovered a new role for a population of white blood cells, which may lead to improved treatments for chronic infections and cancer.
Agricultural Research Service scientists have ways of making seeds talk. They have demonstrated that seeds can reveal genetic information even after they've lost viability, which is the ability to germinate. The research has significant implications for seed bank management.
