A record year for Dublin Zoo
Dublin Zoo is celebrating a bumper year with a record one million visitors in 2011.
The zoo also welcomed 42 new arrivals in the past 12 months including two baby gorillas, hippo and giraffe calves and two red panda cubs.
Attendance jumped by 36,947, up from the previous record of 963,053 in 2010.
Dublin Zoo director Leo Oosterweghel said he was thrilled that so many people helped them achieve the incredible milestone despite closing during the visits of Britain's Queen Elizabeth and US President Barack Obama.
Gene is clue to deafness cause
A single gene may provide important clues to the causes of some types of deafness, research suggests.
When the FGF20 gene was 'knocked out' of mice, the animals appeared healthy but had no ability to hear.
In humans, the gene has already been associated with inherited deafness in otherwise healthy families.
FGF20 codes for one of a family of proteins called fibroblast growth factors. The molecules play key roles in embryonic development, tissue maintenance and wound healing.
Sport can help children learn
Schoolchildren may be able to boost their classroom performance by getting out on the playing field, a study suggests.
A review of previous research found evidence that physical activity can improve academic achievement in children and teenagers.
Scientists in the Netherlands said: "According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance."
