Is there a link between soy formula and attention deficit disorder?

“Does soy-based infant formula lead to attention deficit hyperactivity disorder (ADHD)? There’s much speculation — but little science — on this association. Shedding some light on this problem, a UC Irvine-led study discovered that a mineral found in high levels in soy milk appears to be linked to behavioral problems.

The study in rats, one of the first scientific inquiries into soy milk and ADHD, indicates that the mineral manganese may cause behavioral problems if consumed in high doses. The study appears in the August issue of NeuroToxicology.

Francis Crinella, professor of pediatrics, and his colleagues at UCI and UC Davis found that giving rats increasing levels of manganese during infancy resulted in behavioral changes at higher doses. The researchers also found that manganese exposure resulted in lowered levels of the neurotransmitter dopamine, which plays a key role in inhibiting behavior seen in cases of ADHD.” EurekAlert!

Hubble Spots the Biggest World Since Pluto

A cold new world:

‘Astronomers have dubbed it “Quaoar” (pronounced kwa-whar) after a Native American god. It lies a billion kilometers beyond Pluto and moves around the Sun every 288 years in a near-perfect circle. Until recently it was just a curious point of light. That’s all astronomers could see when they discovered it last June using a ground-based telescope.

But now it’s a world.

NASA’s Hubble Space Telescope has measured Quaoar and found it to be 1300 km wide. That’s about 400 km wider than the biggest main-belt asteroid (Ceres) and more than half the diameter of Pluto itself. Indeed, it’s the largest object in the solar system seen since the discovery of Pluto 72 years ago.’ NASA
