Sea Slugs Turn up Heat on Bleaching

By Ingo Burghardt

Symbiotic sea slugs employ similar zooxanthellae species as corals, offering fresh insights into why heat-stressed corals bleach.

Can Mimicking Nature Quench Our Thirst?

Patterned polymer surfaces based on the African Stenocara beetle could be applied to our roofs to collect drinking water from the atmosphere.

Maintaining a stable supply of drinking water in Australia is a continual challenge. In 2006 the drought that gripped most of the Australian mainland was termed “the worst drought in 1000 years”, with the once-ferocious Murray River receiving only 5% of its average inflow.

A Matter Of Time

Successful treatment of cancer may depend on the accurate timing of chemotherapy or vaccine therapies to match fluctuations in each patient’s immune system.

Not all cancer patients are cured by chemotherapy, biological therapies, radiotherapy or surgery. Some patients can have complete regression of all cancer, while others do not appear to be responding or show some level of clinical response but not enough to overcome the tumour.

This variability has remained unexplained for many decades, and at the end of this week about 800 Australians with cancer will be dead. In the US the numbers will be close to 12,000 per week.

Birth of the Red Sea

New evidence about the creation of the Red Sea has fundamentally changed how geologists understand the birth of oceans.

A 20% rise in the price of soft drinks and flavoured mineral waters would save lives and reduce cardiovascular disease in Australia.

By Gary Sacks, Jane Martin and Lennert Veerman

Earlier this year the United Kingdom announced a sugar tax on soft drinks. The tax will come into effect in 2018, with the funds to be used to address childhood obesity.

Indigenous Genomics

Indigenous Genomics

By Emma Kowal, Simon Easteal & Mick Gooda

Mistrust is a significant but not insurmountable barrier to the acceptance of genomics by Indigenous people.

In 1994 Indigenous people around the world raised the alarm about scientists who wanted to steal their biological material, patent it and make drugs from it. The scientists were part of the Human Genome Diversity Project (HGDP), a companion project to the Human Genome Project that completed sequencing of the entire human genome in 2001.

A New Basis for Nuclear Structure

Evidence being sought that the structure of the bound proton and neutron has changed in a nucleus would herald a new paradigm for the structure of atomic nuclei.

Evidence being sought that the structure of the bound proton and neutron has changed in a nucleus would herald a new paradigm for the structure of atomic nuclei.

By Anthony Thomas

The idea that the internal structure of protons might change under certain circumstances is being put to the test, and could help to explain some inconsistencies in theoretical physics.

Melbourne Observatory Celebrates 150th Anniversary

The Melbourne Observatory celebrates its 150th anniversary this month with a weekend of activities on 23 and 24 November.

Stargazers and history lovers are in for a treat this November when the Melbourne Observatory celebrates its 150th anniversary with a weekend of activities on 23 and 24 November.

A special, colourful historic re-enactment of the opening of the Melbourne Observatory in
1863 will open the weekend’s festivities.

Dressed in period costume, the re-enactment will include the original speeches from the
opening with appearances by the Governor of the day Sir Henry Barkly, Director of the
Gardens Ferdinand von Mueller, and the Government Astronomer Robert Ellery.

Turning Old Tyres into New Roads

By Holly Bennet, University of Melbourne

With millions of tyres dumped in Australia, a new innovation could turn used tyres into permeable surfaces - helping the environment and our future infrastructure

A staggering 51 million used tyres are discarded annually in Australia, causing environmental and health problems like the sea of stockpiled tyres in Stawell in western Victoria.

Only five per cent of used tyres are recycled locally in Australia, but researchers from the University of Melbourne have teamed up with Tyre Stewardship Australia and Merlin Site Services to come up with an innovative way to reuse the rubber.
