London, 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.

In the study, scientists found that the baby animals could distinguish between two and three and in tests consistently picked the higher figure.

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.

Research team led by Randall Flick, a paediatrician at Rochester's Mayo Clinic analyzed data collected from studied the medical records of 5,357 children from Olmsted County who were born between 1976 and 1982.

Washington, Mar 27: Love surely hurts - in fact you really can die from a broken heart, say a new research, which has shed light on "broken heart syndrome".

Unhealthy eating habits and sedentary lifestyle is taking toll on health of people in the UK. Recent study revealed that there was a 74% rise in new cases of diabetes from 1997 to 2003.

But majority of cases are type 2 diabetes linked to obesity. Moreover number of diabetics is increasing at faster pace in UK as compared to US. Researchers analyzed the data from almost five million medical records
