Ancient campfires reveal a 50,000 year old grocer and pharmacy

For the first time in Australia, archaeobotany has been used by researchers from UWA to examine charcoal from ancient campfires in the Western Desert.

They found wattle and other Acacias which proves it was (and still is) used by Indigenous people for tools, food and medicine.

The iconic wattle isn’t just about sports uniforms and the coat of arms – new finds in the oldest archaeological site on the land of the Martu in the Western Desert shows how wattle has defined culture and been important to Australians for over 50,000 years.

Mystery of children’s ‘chalky teeth’ explained

A blood protein blocks hardening of enamel on teeth growing inside the jaw

Australian and Chilean researchers solve a 100-year-old mystery and call for education and research to save millions of teeth worldwide.

Case studies available.

One in five children have chalky tooth enamel – visible as discoloured enamel spots – which often causes severe toothache and decay, and sometimes leads to abscesses, extractions and orthodontic problems.

Now, researchers from The D3 Group (based at The University of Melbourne, Australia) and the University of Talca in Chile, have discovered the mechanism causing molar hypomineralisation, the commonest type of chalky teeth.

They report today in Frontiers of Physiology that chalky molars arise when developing enamel is contaminated by albumin – a protein found both in blood and in the tissue fluid surrounding developing teeth. The trigger appears to be childhood illnesses.

Food and housing crisis for Melbourne’s native bees

City gardens often don’t have the right types of food and homes for native bees and flies, with knock-on effects for our gardens and for biodiversity. Urban ecologist Katherine Berthon from RMIT University found that only 43% of flowers in the Melbourne city gardens she studied were being used by bees and other pollinating insects.

Saving lives after stroke with a small aircraft or ambulance-mounted CT brain scanner

Adelaide company Micro-X (MX1) has started developing a small CT brain scanner that can be fitted in ambulances and emergency aircraft. If successful, the device will allow paramedics and retrieval teams to diagnose and then start treating stroke patients in the golden hour – the first hour after a stroke.

The molecular heart of celiac disease revealed

Researchers discover how our immune cells bind to wheat proteins triggering the condition

Embargo: 1 am AEST Tuesday 29 April 2014

Published in Nature Structural and Molecular Biology

Australian, US and Dutch researchers have determined the molecular details of the interaction between the immune system and gluten that triggers celiac disease. Their work opens the way to potential treatments and diagnostics.

Monash, Melbourne and Leiden university researchers, in collaboration with colleagues from a Boston-based company, have described the molecular basis of how most of the immune cells (T cells) that induce celiac disease lock onto gliadin, a component of gluten, thereby triggering inflammation of the lining of the small intestine. This is what gives many celiac sufferers symptoms similar to food poisoning after eating a slice of toast. Read More about The molecular heart of celiac disease revealed

Jobs at EMBL Australia, PhD training course, and new research

Posted on behalf of Nadia Rosenthal, Scientific Head, EMBL Australia

It’s been a pretty exciting time for EMBL Australia lately, with international visitors, new group leaders, and even a Nature paper.

But the one thing which really stood out for me in the past year was our EMBL Australia PhD Course.

At last year’s course at WEHI in Melbourne, we spent two weeks with 60 passionate and enthusiastic PhD students.

Not only did the students learn the tools of the trade from top researchers, they also formed an invaluable network of peers, who will hold their own student-run symposium in Sydney later this year.

This year we’ll bring together another 60 PhD students at ANU in Canberra. Applications are open now – read on for more details.

Nature paper: Turning on our immune sentries

A team from Melbourne, Monash, UQ and the synchrotron (including core members of the ARC Imaging Centre team) have found what sends our MAITs into action to protect our gut from invaders.

The patented work is the starting point to understanding our first line of defence, and what happens when it goes wrong.  It will lead to new ways of diagnosing and treating inflammatory bowel disease, peptic ulcers and even TB.

asta logo - smallAustralia’s Future: 28 creative careers for adventurous young people in science, technology, engineering and mathematics

Chief Scientist Professor Ian Chubb this morning launched Australia’s Future, a free magazine featuring 28 people and the very different journeys they’ve taken from their studies in science and maths, in the Mural Hall at Parliament House, Canberra.

Dr Liz New, a chemist at the University of Sydney, reckons she’s got the best job anyone could have.

“We have this idea that scientists are the ones who perform best in school or have a focused personality,” says Liz. “For me, the scientific personality is simply anyone who is curious enough to ask questions.”
