How music gets you in the mood

"Like peacock feathers, music is used by humans to attract mates and we've been writing love songs for centuries," said music psychologist Dr Sandra Garrido of the University of Western Sydney.

Given these days we have access to such an unprecedented range of music styles, as part of ABC Classic FM's celebration of the music of passion and heartbreak, we're asking: can science help you decide what music will get you in the mood?

New study shows global sea turtle recovery

An analysis of 299 nesting sites of all seven sea-turtle species found turtle-nest numbers had significantly increased at 95 sites, versus 35 that showed a significant decrease.

The study by an international team of scientists and published today in Science Advances, analysed data taken over an average of 16.2 years, including from waters off Australia, Africa, North and South America, and Asia.

Study: You can't blame tooth decay on your genes

"I think there may be a perception in the community that bad teeth are inherited," said study co-author Associate Professor Jeff Craig, from the Murdoch Children's Research Institute.

"But this research is an important message because it means parents and children themselves can take control.

"We're not doomed by genetics in tooth decay."

First cancer 'living drug' gets go-ahead

The regulator - the US Food and Drug Administration - said its decision was a "historic" moment and medicine was now "entering a new frontier".

The company Novartis is charging $475,000 (£367,000) for the "living drug" therapy, which leaves 83% of people free of a type of blood cancer.

Doctors in the UK said the announcement was an exciting step forward.

The living drug is tailor-made to each patient, unlike conventional therapies such as surgery or chemotherapy.

It is called CAR-T and is made by extracting white blood cells from the patient's blood.

Can our smartphones get any smarter?

"We shall be able to witness and hear events: the inauguration of a president, the playing of a world series game, the havoc of an earthquake or the terror of a battle — just as though we were present," said Dr Tesla in 1926.

The device, Dr Tesla said, would be small enough to carry about in one's "vest pocket".

Vests aren't so common these days, but he's spot on with everything else. Smartphones — combining the traditional function of a phone with internet browsing, video and apps — have changed the way we relate to, and communicate with, the world.

Ten tips for raising tech-savvy and tech-safe kids

But fast-forward to 2017 and you're now responsible for raising a child whose life will revolve around digital technology, and who will have to be tech-smart, tech-savvy, and tech-safe to survive out there in the wild.

So what are some tips to help you along the way?

We asked for your experiences, and expert Joanne Orlando — an analyst and researcher in technology and learning who has worked as an advisor for the Government, for Apple, and for the children's television show Play School — for her best pieces of advice.

How to better manage your relationship with your phone

How does it feel for you? What emotions come up in your mind and body?

What about when you realise you've left your mobile device at home, or in a taxi? Are you bereft? Do you crave it?

Last year, 84 per cent of Australians owned a smartphone — and among young people, that figure was 94 per cent.

And our dependence on mobile devices has crept up on us over time, leading to a range of problems, University of Washington Information School's Professor David Levy said.

Think you're right handed? Try this test

No matter where you are in the world, most people use their right hand for most things. More than 85 per cent of us are right-handed — even foetuses at 10 weeks preferentially move their right hand.

And the preference seems to be just a human thing — our close relatives the apes are split right down the middle on the left/right-handedness. Fifty per cent of them are lefties.

Australian researchers using silkworms to repair damaged eardrums

Who would have thought silkworms could be used to repair damaged eardrums?

A team with researchers based in Perth and Melbourne is moving towards clinical trials of a device that incorporates silk in an ear implant.

Named "ClearDrum", it looks like a contact lens, but is instead a device on which the patient's cells can grow.

Perth-based surgeon Professor Marcus Atlas said silk was the preferred choice because it was flexible.

Are you an addict? Turns out we're all tech junkies

Chances are you're looking at it right now.

Before you try and deny you're addicted, here are some stats to consider:

Australian men unlock their phones more than anyone in the world - on average 45 to 46 times a day, while for Australian women it is around 42 times.

Those figures have been calculated by AntiSocial, an app developed by Melbourne software company Bugbean, to monitor people's use of social media.
