Why kids see a dog when they see a cloud

A new study by Brit scientist has found that children do not see objects in a fully grown-up way until the age of 13.

While adult brains can assume that light comes from above when they have to judge whether shaded images are convex or concave, young children have to learn this ability.
Jim Stone at the University of Sheffield showed embossed shapes such as squares and shaded images such as footprints to 171 children aged from 4 to 10.

Each child was shown 10 images and asked whether they were convex or concave. The ‘correct’ answer assumed an object was lit from above.

The children got better with age, with the average score out of 10 improving by 0.43 each year.

If children of other ages develop at the same rate, Stone predicts that babies will learn to assume that light comes from above at about 21 months.

But this aspect of their visual perception won’t be ‘fully grown’ until the age of 13 or so.
“Children really do see the world differently to adults, inasmuch as their perceptions seem to be more variable,” said Stone.

“No wonder they can’t look at a cloud without seeing a dog or a bear,” he said.

Black rice relieve inflammation caused by allergies

Scientists have reported that black rice — a little-known variety of the grain — may help soothe the inflammation involved in allergies, asthma, and other diseases.

Bran is the outer husk of the grain, which is removed during the processing of brown rice to produce the familiar white rice. Those experiments, which were done in cell cultures, hinted that black rice bran suppressed the release of histamine, which causes

Mendel Friedman and colleagues injected the extract into the mice, it reduced skin inflammation by about 32 per cent compared to control animals and also decreased production of certain substances known to promote inflammation.

Brown rice bran extract did not have these effects, they say. When the scientists fed the mice a diet containing 10 per cent black rice bran, it reduced swelling associated with allergic contact dermatitis, a common type of skin irritation.

The findings “further demonstrate the potential value of black rice bran as an anti-inflammatory and anti-allergic food ingredient and possibly also as a therapeutic agent for the treatment and prevention of diseases associated with chronic inflammation,” the article noted.
