In just over 1,000 years, Icelanders have gone through numerous changes in their gene pool, to the extent that Iceland's first settlers, who came to the island from Norway and the British and Irish isles between the years 870 and 930, are much more similar to the inhabitants of their original home countries than to Iceland's present-day inhabitants.
Stanford and Seoul National University researchers have developed an artificial sensory nerve system that can activate the twitch reflex in a cockroach and identify letters in the Braille alphabet.
The work, reported May 31 in Science, is a step toward creating artificial skin for prosthetic limbs, to restore sensation to amputees and, perhaps, one day give robots some type of reflex capability.
Identify and prioritize treatment options based on a patient's profile of genetic alterations is a major challenge in personalized cancer medicine. Data-driven approaches such as PanDrugs can help to this end. This new computational resource has been developed by researchers from the Bioinformatics Unit at the Spanish National Cancer Research Centre (CNIO) and is described in a paper published in Genome Medicine.
Cell biologists have deepened understanding of proteins associated with neurodegenerative diseases. The findings could open up new treatment approaches for disorders including Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis (ALS), among others.
Researchers in Japan have gained valuable insights into 'stress granules' -- clumps of RNAs and proteins that form when cells are stressed by factors such as heat, toxins and viruses.
Boston, MA -- Humans can accurately sense the position, speed and torque of their limbs, even with their eyes shut. This sense, known as proprioception, allows humans to precisely control their body movements. Despite significant improvements to prosthetic devices in recent years, researchers have been unable to provide this essential sensation to people with artificial limbs, limiting their ability to accurately control their movements.
Sensory-based food education given to 3-5 year-old children in the kindergarten increases their willingness to choose vegetables, berries and fruit, according to a new study from the University of Eastern Finland. Sensory-based food education offers new tools for promoting healthy dietary habits in early childhood education and care. The findings were published in Public Health Nutrition.
Alzheimer's disease patients lose up to 60% of a component called plasmalogen from the membranes of the cells in their brains, but it's still not known how or why. In a paper to be published in the June 1 issue of the Journal of Biological Chemistry, researchers at Washington University in St.
For many people, household chores are a dreaded, inescapable part of life that we often put off or do with little care - but what if a robot maid could help lighten the load?
Hazardous chemicals such as bromine, antimony and lead are finding their way into food-contact items and other everyday products because manufacturers are using recycled electrical equipment as a source of black plastic, according to a new study.
The substances are among those applied to devices, such as laptops and music systems, as flame retardants and pigments but remain within the products when they reach the end of their useful lives.
RIVERSIDE, Calif. -- Drugs available to treat multiple sclerosis, a leading cause of neurological disability affecting roughly 2.3 million people worldwide, alter the body's immune system to reduce disease symptoms and disability.
They do not induce, however, repair of damaged axons, the long threadlike parts of nerve cells that conduct impulses between cells or restore myelin, the protective sheath that surrounds the axons of neurons essential for the proper functioning of the brain and spinal cord.
