London, Dec 18: A new study conducted by researchers at Duke University in Durham, North Carolina, has found a monkey’s ability to handle basic addition is similar to that of humans.

Researchers conducted study with two rhesus macaques and fourteen undergraduates.

London, Dec 18: Women who have suffered a miscarriage or undergone an abortion have three times the normal risk of giving birth to a baby with low birthweight subsequently, say researchers.

The study, based on data from the United States Collaborative Perinatal Project set up in 1959, is published in the Journal of Epidemiology and Community Health.

Low birthweight (under 2500 g) and premature birth (less than 37 weeks) are two of the major contributors to deaths among newborn babies and infants.

London, December 18: A US researcher has come up with an idea to make aeroplanes easier to handle, something that is very important for manoeuvring them in emergency situations.

Ron Blackwelder, an aerospace engineer at the University of Southern California in Los Angeles, proposes to add extra control surfaces or "bellyflaps" to the underside of the aircraft to increase manoeuvrability.

London, Dec 18: Scientists at Oregon Health & Science University’s Neurological Sciences Institute have discovered a body system that determines when a person starts shivering.

The researchers have found a sensory mechanism, which takes temperature information from the skin and determines when a person should start shivering.

Kazuhiro Nakamura, Ph. D., an OHSU Fellow for Research Abroad from the Japan Society for the Promotion of Science said that the study shows the sensory pathway for shivering, which can be thought of as brain wiring.
