what's the buzz


The study led by Dr Dror Mandel and Dr Ronit Lubetzky, Tel Aviv Medical Centre, has found that premature babies who are exposed to music by 18th-century composer Wolfgang Amadeus Mozart gained weight faster — and therefore become stronger — than those who don’t.
The research team discovered infants exposed to Mozart’s music in one session, once per day expend less energy — and therefore need fewer calories to grow rapidly — than when they are not ‘listening’ to the music.
“It’s not exactly clear how the music is affecting them, but it makes them calmer and less likely to be agitated,” said Dr Mendel.
The researchers measured the physiological effects of music. After the music was played, the researchers measured infants’ energy expenditure again, and compared it to the amount of energy expended when the baby was at rest.
After ‘hearing’ the music, the infant expended less energy, a process that can lead to faster weight gain.

Migraine linked to childhood abuse
A new study by the American Headache Society’s Women’s Issues Section Research Consortium strongly suggests that migraine is linked to childhood abuse.
Researchers found that migraineurs who had been physically or emotionally abused as children and/or had suffered neglect had noticeably higher number of comorbid pain conditions compared to those who had not been abused.
Gretchen E Tietjen, University of Toledo Medical Centre, and his team examined 1,348 headache clinic patients with physician-diagnosed migraine to come up with their findings.
Sixty one per cent participants at least one comorbid pain condition and 58 per cent said they had a history of abuse or trauma.
It was seen that the number of maltreatment types suffered in childhood were related to the number of comorbid pain in adulthood.

Exercising in groups is more beneficial
A new research at the University of Oxford’s Institute of Cognitive and Evolutionary Anthropology suggests that exercising in a group can be more healthy than working out alone.
Researchers studied Oxford’s rowing team to come up with their conclusion.
The crew was divided into teams, each with six members and asked to work out with identical rowing machines. The only variable was whether the workouts were done alone, or in teams exercising together, with the six machines coordinated by the crew’s coxswain.
The end of each workout saw the blood-pressure cuff around one arm of each participant being tightened until he reported pain. This was done to measure endorphin levels in the brain. Endorphin is a chemical that not only creates gives a mild high but also blocks out pain. And it was seen that the rowers’ pain threshold was steadily twice as high after exercising in a group than exercising alone even with the same intensity of the workouts.
The researchers concluded that group bonding releases more endorphin.

The benefits of quitting smoking should be stressed
A new study has shown that stressing the benefits of not smoking may work better than emphasising the negative effects of cigarettes in persuading smokers to kick the habit.
Researchers divided 28 specialists working at the New York State Smokers’ Quitline into two groups.
One group was trained to emphasise the benefits of quitting (gain-framed messages) to smokers, while the other group gave standard-care messaging that focused on the potential losses from smoking and the benefits of quitting.
Between March and June 2008, 813 callers received gain-framed messaging, and 1,222 callers received standard messaging.
At two-week follow-up interviews, smokers who received the gain-framed messaging reported more quit attempts and a higher rate of non-smoking than those who received standard-care messaging (about 23 per cent versus 13 per cent).
