Athletes are paid for pushing their bodies to the limit, but at what stage do we acknowledge that baking hot afternoons might not be the safest time for our sportspeople to ply their trade? Certainly…
While they’re very pretty to look at, museum collections are also valuable to science.
Curious Expeditions
We know museums attract visitors who come to view and wonder at their vast array of displays, but they are also used by expert researchers – locally and abroad – who make use of the ever-growing collections…
Without taking risks, science won’t solve big problems.

Few would argue the world isn’t facing enormous challenges: human population growth and the associated demand for resources, mass extinctions or – perhaps the biggest of all – global climate change. We…
What toilet? In this refugee camp, children play in the holes dug for latrines.
Oxfam International
Why does one third of the world’s population have inadequate sanitation? Hopefully I can shed a bit of light on this. You see, my work is shit – literally – which is why I call myself a water, sanitation…
If the World Chess Championship ends in a draw, the players go to rounds of fast chess. How does this differ to traditional chess?

After six games, the 12-game World Chess Championship Match is now led, 4 games to 2, by 22-year-old Magnus Carlsen. This is a very important advantage, but reigning champion Viswanathan Anand is no stranger…
Flooded roads can affect evacuating populations but computer modelling can quickly reevaluate plans to minimise loss of life.

Reports from the Philippines reveal a lack of typhoon preparation and evacuation efforts. When to evacuate – and how – spells the difference between life and death. As we know, typhoons can cause widespread…
Snapchat’s turned down a US$3 billion buyout offer from Facebook … but why?
ryan.nagelmann
Facebook last week was reported to have offered US$3 billion to acquire the Snapchat social network service – an offer that was rejected. The hefty buyout offer (maybe strategically leaked by Snapchat…
Today’s court decision is an important win for Google – and society.

Australia wants to foster innovation in a digital economy, but our copyright laws discourage businesses from investing in new technologies and make it harder for individuals to access the knowledge upon…
A brain the size of a sesame seed, such as that found in a honey bee, is still capable of weighing up decisions.
macropoulos
Everyone knows what it’s like to be uncertain – at least, humans do. But are non-human animals ever uncertain? When we feel uncertainty, instead of risking the consequences of a bad or wrong decision…
A multi-armed robot assists surgery in delicate areas of the body.
Mark Chew
A spider-like robot moves over an anaesthetised patient, deftly making controlled incisions with flexible arms while a surgeon sitting a couple of metres away peers through a console offering highly-magnified…
Chess can be applied to maths education – you just have to think outside the box.
practicalowl
In the spirit of the current world championship bout between Norwegian grandmaster Magnus Carlsen and Indian grandmaster Viswanathan Anand, we should seriously consider the role of chess in how young students…
We’ve known about the energetic jets that spew matter from black holes for nearly a century, but what are they made of?
NASA
While we tend to think of black holes as giant cosmic vacuum cleaners, it’s not all one-way travel. As gas falls in towards a black hole, it spirals gradually inwards like water going down a plug hole…
Statistics can’t tell us everything: p values are only the start of the problem.
chrisinplymouth
Yesterday’s article by Geoff Cumming, based on a very recent Proceedings of the National Academy of Science paper, argued that “null hypothesis significance tests” (NHST) are flawed – and he is correct…
Who will prevail: 43-year-old Anand or 22-year-old Carlsen?

In a previous article in The Conversation, I presented the Norwegian chess prodigy Magnus Carlsen. He obtained the [grandmaster](http://en.wikipedia.org/wiki/Grandmaster_(chess%29) title at the age of…
Stringing optical fibre on power lines isn’t a new idea, but there are better ones.
Sarah Caulfield
Recent reports in The Australian call for the National Broadband Network (NBN) rollout to be sped up by using optical fibre strung overhead with power lines, rather than replacing Telstra’s copper network…
A bit of national pride and a lot of science has sent India to Mars.

Last Tuesday the Indian space agency launched a mission to Mars. Its goal is to place a satellite into orbit around that planet. The probe is currently in Earth orbit (although not quite high enough yet…
A p value of .05 has been the default ‘significance’ threshold for nearly 90 years … but is that standard too weak?
Martin_Heigan
For researchers there’s a lot that turns on the p value, the number used to determine whether a result is statistically significant. The current consensus is that if p is less than .05, a study has reached…
Fundamental, wide-ranging and curious research is the basis of a country’s development. Cuts to CSIRO won’t help.

Like many scientists, I was apprehensive in advance about the Abbott government’s approach to science policy. Would it be pragmatic but fact-based or would it be ideological and politically driven? Sadly…
We’re learning how the earliest rocks formed, and they’re providing a pretty weird picture of the young Earth.
Taran Rampersad
New evidence is shedding light on the processes that formed Earth’s oldest rock and mineral record – processes that influenced the early evolution of life. Over the past 30 years our knowledge of the earliest…
Neuroscience has advanced far beyond public understanding.
Kristian Mollenborg
Are you a left brain or a right brain person? I’ve never met a person who doesn’t know what I mean by this question. The idea that creative people use the right side of their brain more than logical people…
Two of millions of cane toads found across northern Australia.
Mark Lewis, Radio Pictures, Mullumbimby
When cane toads were released in Australia in 1935, they were the latest innovation in pest control, backed by a level of consensus support that a scientist could only dream of. So what went wrong? Research…
Nine years after his death, Yasser Arafat’s remains have produced even more questions.

A Swiss forensic report of the exhumed remains of ex-Palestinian leader Yasser Arafat today suggests polonium poisoning may have been the cause of death – but what is polonium, and why is it so deadly…
Spy vs Spy or spies vs the NZ public? The question we should be asking is: how much does our own government intercept?
Corey.T
An admirable feature of the national security bureaucracy is its persistence. If you don’t get it right (or what you think is right) try, try, try again. On Tuesday, the New Zealand Parliament passed the…
Near field communication isn’t a new phenomenon, but it’s only just now getting a real push into Australia.

Coles and the Commonwealth Bank of Australia declared last month their intention to make use of near field communication (NFC) technology, allowing users to transfer their personal and other banking details…
What is going on inside plant cells? Metabolomics has answers.
