Despite suffering severe pain, about one in three older cancer patients do not end up taking opioids, the most potent of analgesics, according to a new study from Canada.

Drug addicts and their non-addicted siblings share certain features in the brain, suggesting a susceptibility to addiction is inherited but is also a flaw that can be overcome, scientists said on Thursday.
Researchers who scanned the brains of 50 pairs of brothers and sisters of whom one was a cocaine addict found that both siblings had brain abnormalities that make it more difficult for them to exercise self-control.
The findings increase understanding … full story
International scientists on Friday agreed to a temporary two-month halt to controversial research on a bird flu virus that may be easily passed among humans, citing global health concerns.

Landscape artist Jane Anderson struggled with seasonal affective disorder in the winter months. She tried meditation and noticed a change within a month.
“My experience was a sense of calmness, of better ability to regulate my emotions,” she says.

More than the apple, a strawberry a day could keep not just one doctor away, but an entire army of brain, hormone and cancer specialists.
Fisetin is a natural flavonoid found very abundantly in strawberries and to some extent in other fruits, vegetables, tea and red wine. It eases diabetes complications, Salk Institute’s Cellular Neurobiology Lab (CFL) said.
Flavonoids are natural compounds having similar effects as antioxidants, which help protect … full story
One way of prompting physical activity among children is to promote them duringleisure time, tailored to the specific gender.
Researchers found children’s perceptions of what constituted play included both physically active and sedentary behaviours.

If you want to improve the way you eat, the best way to do so is to first make an action plan and then visualise yourself carrying it out, researchers say.
“Telling people to just change the way they eat doesn’t work; we’ve known that for a while,” says Bärbel Knäuper of McGill’s Department of Psychology.
“What we’ve done that’s new is to add visualisation techniques to the action plan,” adds Knauper, the journal Psychology and Health reports. … full story
Boys seem to get a greater kick out of caffeine than girls, according to the results of a double-blind study.
Boys also credited caffeine with having a positive effect on their athletic performance, not so girls.
The study, conducted by Jennifer L. Temple, neurobiologist and assistant professor of nutrition sciences at the University at Buffalo in the US, is the first to show how genders respond to caffeine consumption.
“We are hoping that our … full story
