Soil, dust and air-based exposure to lead can interfere with a child’s developing nervous systems and cause behavioural and developmental problems.
Reporter Scott McIntyre lost his job with SBS following several controversial tweets on Anzac Day – but does the Fair Work Act protect the right to political expression?

Scott McIntyre’s legal challenge against being sacked by SBS will be an interesting test of whether the Fair Work Act offers any safe haven for employees to maintain a personal and political identity.
Anyone teaching encryption without first getting clearance from the government could soon be wearing these.

The government’s Defence Trade Controls Act effectively makes teaching encryption a criminal act and considers even a simple calculator as a potential weapon.
Australian cattle wait to be loaded onto a ship to Indonesia. Their voyage to the United States would be even longer.

Australia’s cattle industry is keen to begin live exports to the United States. But America is very different to existing live export markets such as Indonesia, making the move much more ethically fraught.
The earliest sources, including Paul’s letters, show very little interest in the mythological details of heavenly existence.

Interpretations of Paul the apostle’s texts provided the basic fund of imagery that continues to inform popular opinion about what Christians mean when they talk about “heaven”, or “hell”.
The story of Johnny Depp’s dogs and their potential fate attracted global media attention.

Behind the uproar over Johnny Depp’s dogs lies a serious and evolving idea: our animal companions have an important place in our lives that entitles them to rights akin to a sort of citizenship.
Two sides of the same coin? Convergence theory explains why the Labor and Liberal parties are often closer together on issues than they like to portray.

Convergence theory – which holds that the main Australian political parties will, over time, converge upon near-identical policy positions on most issues – was on full display during budget week.

Federal parliament has passed legislation that removes Norfolk Island’s self-government but strong local views about the tiny island’s independence have deep historical roots.
Not all eyes are on the prize: Eurovision is often as much about undeclared alliances, voting blocs and political paybacks.

For the first time, Australians can vote for this year’s Eurovision winner. But it’s as much a political battlefield as a song contest – so hopefully the Russians have forgotten the “shirtfront”.
The Fukushima disaster was a dark chapter for nuclear power - but high-profile accidents are far from the only downside.

Is nuclear power worth it? No, says Mark Diesendorf – it’s never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
Looking over Palmerston and the East Arm of Darwin Harbour to the new $35B Inpex LNG plant. Many resources projects in the north are in beautiful, environmentally important places.
Andrew Campbell
This year’s federal budget outlined plans for infrastructure in northern Australia, but it will need to do more than build roads and rail to sustainably develop the north.
All music is good for kids, not just ‘Mozart for babies’.

A majority of Australians agree we have a problem with alcohol. But almost all say that it’s not a problem of theirs – it’s a problem that exists somewhere outside of their world.
It’s hard for a human to keep an eye all the players’ performance in any game, such as this typical AFL match at the MCG in Melbourne. So let the machines do all the work.

When it comes to keeping an eye on all the action in sport a coach can only see so much. But machine learning can crunch all the data and look for improvements.
Films such as Avatar idealise indigenous people as Noble Savages, enjoying simple and uncorrupted lifestyles until contact with colonisers.
Nicole Hanusek
In a recent study, of the 53 films watched that had at least one anthropologist as a character, just under half belonged to the horror genre. Why should that be the case? And how were indigenous peoples in those films portrayed?
Sweat is made up of water and minerals that are collectively known as electrolytes.

Sports drinks claiming to contain electrolytes have innundated stores in recent years. So what are electrolytes? Are they good? How can we best get them?

North Korea does not yet have the capacity to launch a nuclear missile from a submarine. Its recent test, however, suggests it is making progress to a game-changing second-strike capability.
Prime Minister Tony Abbott says an inquiry into iron ore competition “could make sense”.
Alan Porritt/AAP
While it’s easy for the large miners to argue increased iron ore production is business as usual, the overall cost to the sector warrants a closer inspection.
Who’ll use the equipment if funding for researchers is cut back?

A large new national park might sound like the best way to protect the critically endangered Leadbeater’s possum. But it won’t do anything to save possums from the major threat of bushfire.
Since the NT Intervention a large body of evidence has built up showing that income management does not achieve its stated goals. So why does it continue?
AAP/Dean Lewins
Various studies, culminating in the final evaluation report of income management in the Northern Territory, have found such programs don’t achieve the claimed benefits. Why did the budget extend them?
Older workers and retirees are fast becoming Australia’s most significant age group of voters – but future federal governments will struggle to pay for their retirement without serious reform.
Dan Peled/AAP
Within three years, Australians will face a $100 billion bill just to cover the age pension and super tax breaks. That bill is set to keep rising; by 2025, one in three of us will be 55-plus.
