Parkinson's drugs linked to gambling
People with Parkinson's disease were urged yesterday to be candid with doctors if they developed a gambling habit, following evidence that drugs used to treat the condition might, on rare occasions, trigger compulsive behaviour. Patients have lower than normal levels of dopamine, a compound which transmits nerve impulses, so often take a drug that mimics the chemical. The medication seems to unbalance parts of the brain which control emotions and one's internal "reward system".

Hands-free cellphones carry car crash risk
Using hands-free cellphone headsets while driving is not risk free. People who chat on their mobiles while driving are four times more likely to crash - and that includes those using hands-free devices. The research, conducted in Perth, Western Australia, was based on 456 drivers who had been involved in road crashes requiring hospital attention. By comparing the time of crash with records from phone companies, it was found that cellphone use significantly increased the chance of a crash. That was regardless of sex, age group, or whether or not a hands-free device was used.

Gorilla deaths show tourists should keep their distance
Poaching is the biggest killer of mountain gorillas, but respiratory diseases come a close second, accounting for about a quarter of deaths, according to a major survey. The Mountain Gorilla Veterinary Project, based in Rwanda, investigated 100 gorilla deaths dating back to 1968. The team found that 40 were due to trauma, for which poaching is almost always the cause in adults. More surprising was the detrimental effect of respiratory diseases, including influenza A and parainfluenza viruses, which killed 24 of the animals.
