Massive galaxies with extra-large extended “puffy” disks produced stars for longer than their more compact cousins, new modelling reveals.
In a paper published in the Astrophysical Journal, researchers led by Dr Anshu Gupta and Associate Professor Kim-Vy Tran from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D), show that the sheer size of a galaxy influences when it stops making new stars.
A proof-of-concept published today in Nature promises warmer, cheaper and more robust quantum computing. And it can be manufactured using conventional silicon chip foundries.

Most quantum computers being developed around the world will
only work at fractions of a degree above absolute zero. That requires
multi-million-dollar refrigeration and as soon as you plug them into
conventional electronic circuits they’ll instantly overheat.
But now researchers led by Professor Andrew Dzurak at UNSW
Sydney have addressed this problem.

Have you seen a sawfish—alive, or on the wall of a pub? Your information can help these scientists help the sawfish. And we have HD footage of a sawfish sensing the electrical fields generated by a fish, then slicing and dicing it.
You can read more about each of these stories below, including details of scientists to interview.

The shape of a perfect storm: saving lives by predicting firestorms
Scientists available for interview – details and photos below.
Correction: an earlier version stated the tool is being formally trialed by the NSW Rural Fire SERVICE. It is currently in use, but formal trials ended in 2016.

Firestorms are a nightmare for emergency services and anyone in their path. They occur when a bushfire meets a ‘perfect storm’ of environmental conditions and creates a thunderstorm.
Dr Rachel Badlan and Associate Professor Jason Sharples are part of a team of experts from UNSW Canberra and ACT Emergency Services that has found the shape of a fire is an important factor in whether it will turn into a firestorm.
Fires that form expansive areas of active flame, rather than spreading as a relatively thin fire-front, are more likely to produce higher smoke plumes and turn into firestorms, the researchers found.
This finding is being used to underpin further development of a predictive model for firestorms. The model was trialed in the 2015 and 2016 fire seasons by the ACT Emergency Services Agency and the NSW Rural Fire Service, and now forms part of the national dialogue around extreme bushfire development.

It’s not every day that school students get to present their science project to a major scientific conference, and rarer still to receive a prize for it from a Nobel Laureate.
That’s the happy experience today for a team of four Year 11 students from Gosford High School, who have won a national competition conducted by UNSW and the Australian Institute of Physics.
Quantum computers promise ultra-powerful, high speed number crunching. They’ll help us to search vast databases and model biological molecules at an atomic level. They will crack the encryptions we rely on for banking and online security but also help us make new, unbreakable codes.
A new, cheaper way to deliver accurate time across Australia: instead of using hydrogen maser clocks costing hundreds of thousands of dollars we can bounce signals through the national’s optical fibre network according to physics leaders speaking today and tomorrow.
Also today at the national physics congress in Sydney, meet the man whose job it is to figure out how to build the NBN.
And hear about the magic of thermal plasmas, from safer arc welding to saving the ozone layer.
And what are the benefits for Australian research?
Today in Washington DC, the Australian Ambassador Kim Beazley will open a four day workshop with more than 60 US defence researchers and 33 Australian nanotechnology scientists.
The meeting, organised by the US Air Force Office of Scientific Research and the Australian National Fabrication Facility (ANFF), will explore opportunities for collaboration in nanotechnology and nano-manufacturing.
We are a team of science writers, science publicists, science communicators, and science editors.
We help you communicate complex ideas simply to the public, media, government, and industry.
We work on all platforms from social media, to media, pitches, publications, events and conferences.
Scientists: if you need help with your research communication;
Journalists: if you’re looking for talent for your next story; you’re in the right place.
Media and communication training
Full day hands-on workshops in small groups. Practise interviews with journalists. Find your key messages. Handle tricky questions. Learn how to ensure your research is reported accurately.
Sarah's structure of the course, specific insight and understanding of science, her contacts and common mistakes made in communication were great and furthered my skills in this area.

This is one of the best science communication courses I have ever encountered. It teaches all research to think out of box and really simplify their research in lay man's language. I will highly recommend this to anyone looking to learn more about science communication.

Good mix in terms of topics covered, people invited and media coverage. This course will make me more comfortable and I believe it will improve my confidence about myself and how I talk about my work in front of media.

Pushed me to finesse/develop a pitch, find an edge that will facilitate communicating my research findings. The real world experience/opportunity for interviews was exceptionally helpful
