Baby birds can do arithmeticLondon, Apr 2: Baby birds can count and perform basic arithmetic, say researchers.

The study, conducted by scientists from the universities of Padova and Trento, has shown chicks'' ability to add and subtract objects as they were moved behind two screens.

Lucia Regolin, the study''s author, said the animals "performed basic arithmetic" to work out which screen concealed the larger group of objects.

Vehicular pollutants stick to the lung more than other smoke, dust particles

London, April 2: In what may lead to a change in the way air pollution is evaluated, scientists at Lund University in Sweden have shown that the tiny particles from traffic fumes are far "stickier" than other smoke and dust particles.

Research leader Jakob Londahl came to this conclusion after measuring how many airborne particles stay behind in the lungs.

For that purpose, the researchers used a new device called RESPI, which brings air being inhaled in through one chamber, and exhaled air out through a second chamber.

The device helped the researchers analyse particle number and size in both chambers.

Recent study revealed that children exposed to anesthesia during first three years of their life are at higher risk of developing learning disabilities when they grow up. Previous studies have shown that anesthetic drugs can lead to abnormalities in the brains of young animals.
