A new study gives insight into the behavioral medications that medical caregivers sometimes prescribe for kids with Down syndrome.

The impact of scary TV on children's wellbeing has been overstated, according to a new paper. While research has shown that a small minority of children can have extreme reactions to a scary program, overall there is very little sign of increased anxiety, fear, sadness or sleep problems. 

An artificial intelligence system has for the first time reverse-engineered the regeneration mechanism of planaria, small worms that can regrow body parts. This is the first model of regeneration discovered by a non-human intelligence and the first comprehensive model of planarian regeneration, which had eluded human scientists for over 100 years. 

The capacity to recall specific facts deteriorates with age, but other types of memory do not, according to research conducted by Wilma Koutstaal (University of Minnesota) and Alaitz Aizpurua (UPV/EHU-University of the Basque Country), which concludes that the memory of older adults is not as deficient as has been thought until now. Elderly people remember fewer specific details than younger people and, in general, both groups retain concrete information about events experienced better than abstract information. The main difference is to be found in the capacity to remember more distant facts: youngsters remember them better.

Scientists synthesizing nanoscale materials using simple and highly efficient flame technology have been able to “bake” nanostructures using tin oxide, which opens up a wide field of possible new applications.

Metal oxides in bulk form are generally brittle, which limits their desired utilizations. Their one-dimensional (1D) structures, such as belt-like nanostructures, exhibit much more application potential because of their high surface to volume ratio. This ratio induces extraordinary physical and chemical properties, including a high degree of bendability.

New research has shown that pH lowering of municipal water supplies, a common strategy used to control the release of soluble lead from plumbing materials, can affect corrosion of cast iron water mains, resulting in increased levels of both particulate iron and particulate lead in drinking water.

The results of intensive laboratory and field testing of samples from a municipal system following consumer complaints of "red water" and the link between iron corrosion and lead leaching are described in an article in Environmental Engineering Science.
