Mathematical Equation Calculates Cost of Walking for First Time

Why do tall people burn less energy per kilogram when walking?

Any parent that takes their kid out for a walk knows that children tire more quickly than adults, but why is that? Do kids and small adults walk differently from taller people or do they tire faster for some other reason? Peter Weyand from Southern Methodist University, USA, is fascinated by the effect that body size has on physiological function.

Our Brains Wiring For Attention!

Some demand a little more attention than others

University of Utah (U of U) medical researchers have uncovered a wiring diagram that shows how the brain pays attention to visual, cognitive, sensory, and motor cues. The research provides a critical foundation for the study of abnormalities in attention that can be seen in many brain disorders such as autism, schizophrenia, and attention deficit disorder.

Lead May Be the Culprit in ADHD

100128130227-large

Lead, which is sometimes found in paint in older homes, can get on the hands of children and be ingested.

ADHD, or attention-deficit/hyperactivity disorder, is among the costliest of behavioral disorders. Its combination of inattention, impulsivity and hyperactivity leads to accidental injuries, school failure, substance abuse, antisocial behavior and more. Yet despite nearly a century of study, the disorder’s roots remain mysterious.

Laboratory mouse.

At birth, children with Down syndrome aren’t developmentally delayed. But as they age, these kids fall behind. Memory deficits inherent in Down syndrome hinder learning, making it hard for the brain to collect experiences needed for normal cognitive development.

Mobile phones and other cordless telephones have a biological effect on the brain, according to new research.

A study at Örebro University in Sweden indicates that mobile phones and other cordless telephones have a biological effect on the brain. It is still too early to say if any health risks are involved, but medical researcher Fredrik Söderqvist recommends caution in the use of these phones, above all among children and adolescents. Few children who regularly use mobile phones use a headset often or always, even though the Swedish Radiation Safety Authority recommends this.

Children With Autism Show Slower Pupil Responses, Study Finds

The Human eye

Autism affects an estimated 1 in 150 children today, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined. Despite its widespread effect, autism is not well understood and there are no objective medical tests to diagnose it. Recently, University of Missouri researchers have developed a pupil response test that is 92.5 percent accurate in separating children with autism from those with typical development. In the study, MU scientists found that children with autism have slower pupil responses to light change.

Participants were asked to complete patterns in the Raven’s Standard Progressive Matrices (RSPM) — a test that measures hypothesis-testing

Autistics are up to 40 percent faster at problem-solving than non-autistics, according to a new Université de Montréal and Harvard University study published in the journal Human Brain Mapping. As part of the investigation, participants were asked to complete patterns in the Raven’s Standard Progressive Matrices (RSPM) – test that measures hypothesis-testing, problem-solving and learning skills.
