For years, researchers have documented both gastrointestinal issues and problematic behaviors, such as aggression, in many children with autism spectrum disorder.
Researchers from the University of Missouri have now found that both internalizing and externalizing problem behaviors might indicate gastrointestinal distress in children and adolescents with autism.
An Australian-led team of astronomers using the Gemini South telescope in Chile have successfully confirmed the distance to a galaxy hosting an intense radio burst that flashed only once and lasted but a thousandth of a second. The team made the initial discovery of the fast radio burst (FRB) using the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope.
The critical Gemini observations were key to verifying that the burst left its host galaxy some 4 billion years ago.
URBANA, Ill. - Conflict over resource extraction is rampant in sub-Saharan Africa, with small-scale miners violently pitted against multinational mining corporations - and the state security forces that protect them - for access. Attempts to solve the problem by imposing Western environmental systems and regulations aren't working. But it's not for the reasons most experts might suspect, according to a new Illinois study.
MicroRNAs are tiny molecules of nucleic acid that control gene expression, acting like a dimmer switch to tone down gene output at key positions in the network of information that governs a cell's function. MicroRNAs are important for the day-to-day inner working of cells and especially important during development. They also become profoundly defective in diseases such as cancer. Unlike most other human or animal genes, microRNAs are often encoded in genomes and expressed as beads-on-a-string groupings, known as polycistrons.
LA JOLLA--(June 27, 2019) There are hundreds of thousands of distinct colors and shapes that a person can distinguish visually, but how does the brain process all of this information? Scientists previously believed that the visual system initially encodes shape and color with different sets of neurons and then combines them much later. But a new study from Salk researchers, published in Science on June 27, 2019, shows that there are neurons that respond selectively to particular combinations of color and shape.
Losing a limb, either through illness or accident, can present emotional and physical challenges for an amputee, damaging their quality of life. Prosthetic limbs can be very useful but are often expensive and difficult to use. The Biological Systems Engineering Lab at Hiroshima University has developed a new 3D printed prosthetic hand combined with a computer interface, which is their cheapest, lightest model that is more reactive to motion intent than before. Previous generations of their prosthetic hands have been made of metal, which is heavy and expensive to make.
In many ways, a cell is like a city. Proteins or people do daily work to keep the economy going, and items are imported and exported for trade. Imports are shipped into cells by way of endocytosis. Before reaching their final destination, they are kept at the early endosome, a structure that determines whether the material will be disposed, recycled or delivered to a specific region in the cell.
People who report a declining quality of sleep as they age from their 50s to their 60s have more protein tangles in their brain, putting them at higher risk of developing Alzheimer's disease later in life, according to a new study by psychologists at the University of California, Berkeley.
The new finding highlights the importance of sleep at every age to maintain a healthy brain into old age.
Financial crises not only result in severe disruptions to the economic system, they also affect people's life satisfaction. A new study by Martin Luther University Halle-Wittenberg (MLU) and the Halle Institute for Economic Research (IWH) shows that weaker members of society are more affected by increased uncertainty during crisis times, even if they may not be speculating on the stock market themselves. This could potentially also lower their propensity to consume, thereby intensifying the impact of a financial crisis. The study was recently published in "The B.E.
In a pilot study of 14 older adults with mild cognitive problems suggestive of early Alzheimer's disease, Johns Hopkins Medicine researchers report that a high-fat, low-carbohydrate diet may improve brain function and memory.
Using cutting-edge electron microscopy, researchers from Aarhus University have determined the first structures of a lipid-flippase. The discoveries provide a better understanding of the basics of how cells work and stay healthy, and can eventually increase our knowledge of neurodegenerative diseases such as Alzheimer's.
San Diego, CA - June 27, 2019 - Meal delivery drivers bringing food to homebound seniors can be an effective early-warning system for health and safety problems, according to a new study published in the Journal of the American Geriatrics Society by researchers at the West Health Institute, Brown University and Meals on Wheels America.
In a recent study with 3 to 7-year-old children provided an example of how children's daily living environment and motor skills are closely related in the Finnish context. The main finding revealed that residential density is related to children's motor skills, engagement in outdoor play and organised sports. It was found that Finnish children living in the countryside spent more time outdoors and had better motor skills than their age peers in the metropolitan area. On the other hand, children living in the metropolitan area participated the most in organised sports.
Water is a vital resource for people and the environment. One of the most important sources is groundwater which is renewed from precipitation or surface water. Population growth as well as agriculture and industry strongly influence the quantity and quality of groundwater. To be able to investigate groundwater resources more easily, cost-effectively and comprehensively than in the past, researchers at Karlsruhe Institute of Technology (KIT) have developed a new method with Australian colleagues which they are now unveiling in the Reviews of Geophysics journal.
Insights into how a gene that increases the risk of Alzheimer's disease disrupts brain cells have been revealed by scientists.
Brain tissue from people with Alzheimer's showed that a protein called clusterin builds up in vital parts of neurons that connect cells and may damage these links.
Scientists say the findings shed light on the causes of the disease and will help to accelerate the search for a treatment.
