For all the couples planning to conceive on Valentine's Day doctors say the best way to go about is to give-up smoking to increase fertility. The maternity figures taken from the U.K.'s Office of National Statistics say February is the most popular month to conceive, and consequently, the most babies are born nine months later in October.

A new study by U.S. researchers claims to have found the cause of the mysterious Sudden Infant Death Syndrome (SIDS) that kills babies in their sleep. Researchers say that SIDS is a neurological disorder caused by abnormalities in the brainstem that helps control heart rate, breathing and body temperature.

For the study, Hannah Kinney, a neurologist at the Children's Hospital Boston and senior author of the study, and David Peterson of Harvard Medical School, Mass., examined the brains of 31 babies who died from SIDS and ten others who died from other causes

Scientists in the U.S. say they have discovered the cause of cot deaths - an obscurity that leaves hundreds of babies dead every year.

Researchers also say that the evidence points to the fact that there is a genetic factor involved, which could be treatable

Researchers at the Manchester University say they have found the reason behind the sudden infant death syndrome (SIDS) or cot death.

They show that babies born with variations of three genes had 14 times more likely to die from cot death

Researchers say that babies with flaws in three key lung genes can increase their risk of dying from cot death by 14 times.

A Manchester University team said the results of the study could help identify babies who are at risk
