A research team from the University of the Basque Country, led by Basilio Sierra, is devising a robot that can get around by itself. Tartalo is able to identify different places and ask permission before going through a doorway.
The leader of the team that made the discovery, Professor Christopher Rowe of the Austin Hospital in Melbourne, says early diagnosis and treatment presents medical practitioners with the best opportunity to delay the onset of Alzheimer's.
"While the discovery is at an experimental stage, this work places Australia at the forefront of neuro-imaging in Alzheimer's disease," Professor Rowe says.
On your marks, get set
go to lane 1?
Researchers at the University of Alberta in Edmonton studying the connection between loud sounds and reaction time are reporting findings that may have sprinters thinking twice about lane assignments at the upcoming Olympics.
More than half of California's preschoolers attend center-based early care and education programs, but the children who have the most to gain from preschool frequently are those least likely to participate in the programs, according to a new RAND Corporation study.
Washington, DC A new study released today offers a potential predictive technique to anticipate how individuals might behave during a psychotic episode. The study, in the June 18 issue of The Journal of Neuroscience, related the brain activity of healthy participants to how they behaved after exposure to ketamine (a psychosis-inducing drug that mimics schizophrenia symptoms). The findings help explain why schizophrenia symptoms vary greatly from person to person and may ultimately help personalize diagnosis and intervention.
June 17, 2008 -- Nutrition researchers at Washington University School of Medicine in St. Louis have identified five common genetic variations that increase the risk of metabolic syndrome, a group of factors linked to heart disease and diabetes. Another variant they found appeared to protect against the condition.
Mount Sinai researchers have discovered that polyphenolics derived from red grape seeds may be useful agents to prevent or treat Alzheimer's disease (AD). The new study entitled, "Grape derived polyphenolics prevent Aâ oligomerization and attenuate cognitive deterioration in a mouse model of Alzheimer's disease," was published in The Journal of Neuroscience. This new study explored the possibility of developing 'wine mimetic pills' that would replace the recommended beneficial glass of red wine a day for AD prevention.
St. Louis, June 16, 2008 — A group of steroids found in female mouse urine goes straight to the male mouse's head, according to researchers at Washington University School of Medicine in St. Louis. They found the compounds activate nerve cells in the male mouse's nose with unprecedented effectiveness.

A compound found in grape seed extract reduces plaque formation and resulting cognitive impairment in an animal model of Alzheimer's disease, new research shows. The study appears in the June 18 issue of The Journal of Neuroscience.
Lead study author Giulio Pasinetti, MD, PhD, of Mount Sinai School of Medicine and colleagues found that the grape seed extract prevents amyloid beta accumulation in cells, suggesting that it may block the formation of plaques. In Alzheimer's disease, amyloid beta accumulates to form toxic plaques that disrupt normal brain function.
