Middle ear infections are one of the commonest childhood complaints. Ear infections and the sleepless nights that they cause for children and their parents are being tackled by researchers in Perth who are trialling a new treatment.
How can sea squirts help us understand IVF? A Sydney researcher has shown that the influence of sperm extends well beyond the moment of conception. It seems the slower sperm produced stronger, fitter and longer living larvae.
Is there a Eureka finalist near you? Read on to find out, and call us if you’d like to chat with them. $170,000 will be awarded in 17 prize categories, from research to commercialisation, journalism to education on September 4.

And finally: pathways to new epilepsy treatments. A big paper is coming out in Nature on Monday with a 3 am embargo – a consortium led by Melbourne and US scientists will reveal their research into underlying causes of epilepsy.
Full details in the AusSMC embargo list today or email me for a bit more detail – it’s not our story but we can pass you on. If you’re not on the AusSMC embargo list, you can get in touch at www.smc.org.au/for-media. It’s a great resource for covering breaking science news.

Sticky ear mystery solved: trial of treatment underway in Perth
Embargo: tonight, Friday 8 August, 7pm
Perth researchers are planning to end the sleepless nights that families face when ear infections strike and won’t go away. Their research could reduce the need for antibiotics and surgery, and help tackle hearing loss in indigenous communities.
Dr Ruth Thornton and her research team at the University of Western Australia have discovered that sticky nets of DNA hide the bacteria in the ears of kids with recurrent middle-ear infections, where they evade antibiotic treatment by creating impenetrable slimy biofilms.
It is similar to what happens in the lungs of people with cystic fibrosis, where a treatment known as Dornase alfa is used to break this sticky DNA up.
Ruth and her team are now trialling this treatment in the ears of children when they are having grommets put in and a study on the DNA net discovery was published in the online science journal Plos One in February.

The fastest sperm may not be best: Sydney sea squirts show that there’s more to fertilization and IVF than we thought
Embargo and press call: 10am, Wednesday 14 August
For sea squirts the key to a long and happy life is to be fertilized not by a fast sperm, but by one that stands the test of time, Dr Angela Crean, from the Evolution and Ecology Research Centre at the University of NSW, has found.
Her discovery, published in PLoS, shows for the first time that the influence of sperm extends well beyond the moment of conception. If further studies show the same effects in human sperm, the finding could change some of the assumptions currently deployed in IVF practice.
Angela’s research revealed a remarkable fact. Eggs penetrated within minutes by speedy sperm tended to be either non-viable, or produced larvae which died young. The strongest, fittest, longest lived sea squirts were those fertilised by sperm which swam for an hour before reaching the egg.
“This is surprising because it suggests that a sperm’s influence on offspring extends beyond just the DNA it carries,” said Angela, an ARC DECRA fellow.

“Science is not just about deep insights and impressive data. It’s also beautiful and inspiring. The photographs entered into the New Scientist Eureka Prize for Science Photography illustrate science in all its beauty and wonder,” says Michael Slezak, Australasia Reporter, New Scientist.
The winner of the prize will be announced in the presence of 700 science, government, cultural and media leaders at Sydney Town Hall on Wednesday 4 September 2013.
