NZ man arrested after drugs worth close to $800m seized from yacht

Australian Federal Police say the 33-year-old man is one of two men arrested on board a yacht carrying a tonne of the illicit drug also known as P.

Police say the haul has an estimated street value of up to $A750 million ($NZ789m).

The yacht was intercepted off the New South Wales coast near Lake Macquarie, after an international sting involving agencies from Australia, New Caledonia and the United Kingdom.

Drug 'reverses' ageing in animal tests

They have rejuvenated old mice to restore their stamina, coat of fur and even some organ function.

The team at Erasmus University Medical Center, in the Netherlands, are planning human trials for what they hope is a treatment for old age.

A UK scientist said the findings were "impossible to dismiss", but that unanswered questions remained.

The approach works by flushing out retired or "senescent" cells in the body that have stopped dividing.

They accumulate naturally with age and have a role in wound healing and stopping tumours.

New drug for one in five breast cancers

Biological therapies can help fight breast cancers caused by rare, inherited genetic errors like the BRCA one actress Angelina Jolie carries.

Now a new study by experts at the Wellcome Trust Sanger Institute suggests these targeted drugs may also work in many other women who do not have these risky genes.

The drugs could be effective in one in five breast cancers, say the researchers.

That's 20% of patients - far more than the 1 to 5% who develop the cancer alongside having faulty BRCA genes.
