DNA sequencing means a scientist can take a bucket of seawater and ID every fish in the area. Now we need a universal 'biobank' of samples to make a truly powerful environment monitoring tool.

Manusia pertama yang sampai ke Australia mungkin menavigasi lautan unuk menyeberang hingga barat laut pesisir benua tersebut lebih dari 50.000 tahun lalu.
The sustainable choice for sustaining your brain?
How you prepare your coffee at home (and wash up the mugs) can have a big impact on its carbon footprint. So fill that kettle carefully, and only brew what you know you'll drink.
As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty.
Hamish Pritchard/British Antarctic Survey
What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
We need a simple system for categorising data privacy settings, similar to the way Creative Commons specifies how work can be legally shared.
Imagine if we could specify our general privacy preferences in our devices, have them check privacy policies when we sign up for apps, and warn us if the agreements overstep.
Marine heatwaves can kill off species and alter ecosystems.
Marine heatwaves have had little attention until recently, but they're already having large effects.

The first people to make it to Australia could have navigated their way by sea crossing, reaching the north-west coastline of the island continent more than 50,000 years ago.
Information warfare in cyberspace could replace reason and reality with rage and fantasy.
Simulation models show just how effectively fake news and propaganda can shift opinions.
If you drop your food, it’s less about time spent on the floor and more about the surfaces.

The "sniff test" doesn't work every time, and other food safety tips.
The Murrumbidgee River is one of several sites in the Murray-Darling Basin where improvements are being detected.
The Murray-Darling Basin Plan has been politically fraught and mired in scandal. But environmental monitoring suggests that the health of the rivers is indeed improving – even if it will take decades.
It was a hot year for many Australians.
An annual assessment of the health of Australia's environment shows mostly stable conditions in 2017, but ecosystems on land and at sea suffered ever higher temperatures.
Autonomous vehicles are information-rich platforms thanks to the range of sensors on board that track, monitor and measure everything.
Sensors that monitor everything a self-driving vehicle does can help determine who is responsible in the case of an accident – the manufacturer, the service centre or the vehicle owner.
British theoretical physicist and cosmologist, Professor Stephen Hawking in 2014.
Stephen Hawking inspired people with his work on black holes and other mysteries of the universe. Many were quick to pay tribute to the theoretical physicist who died today in the UK, aged 76.
Flies will often sleep on the underside of leaves, to escape from heat and predators.

Flies need good grip because they often sleep upside down.
X-ray vision is not only possible, it already exists – but using computers, not eyes.
Marcella Cheng/The Conversation
Human eyes don't have x-ray vision. But we can use radiography machines to allow our eyes to see inside things the human eye cannot.
Uncountable numbers of drink containers end up in the ocean every year.
Drink containers end up in the ocean at a truly alarming rate. Simply paying people a small amount to return them cuts that rate by nearly half.
We need to measure the volatile compounds that waft off the products in our homes and offices.
A surprising study published in Science found that as fuel emissions drop, consumer products are playing a larger role in air pollution.
Estimating shark numbers is extremely difficult and very contentious.
New research has used genetic analysis in a world-first effort to accurately estimate Australian and New Zealand white shark numbers.
A fly’s eye view of a rapidly approaching swatter.

Why are flies so easily able to evade our attempts to swat them?
Trust is everything.
Politicians are always being told to trust what climate scientists are telling them. But can you have too much of a good thing? What happens when the exchange of ideas becomes too cosy?
