Populations of freshwater species are in a state of deep decline. But we know why and we can reverse the trend.
Nanotechnology and materials are the source of countless innovations, but we don't accurately know how they are affecting humans and the environment.
Spraying an antenna onto a flat surface.
Drexel University Nanomaterials Lab
A new type of material can make it easy to put antennas almost anywhere – no matter how thin the space, or even on surfaces people need to be able to see through.
Could there be a future with smaller, less bulky VR headsets?

Using nanostructures on a flat piece of glass can make lenses smaller, lighter and much cheaper – while providing better image quality.
Subbing new risks for the current dyes’ dangers?
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
Strange new materials that propel the fictional Star Trek universe are being developed by scientists in reality today. Above, the USS Discovery accelerates to warp speed in an artist’s rendition for the TV series Star Trek Discovery.
Advanced materials that seem like they come from Star Trek are becoming reality today.
New research shows bees see a blue halo around flowers thanks to nanostructures on its petals.
Molecular machines are ready to join forces and take on real-world work.
Research on molecular machines won last year's Nobel Prize in chemistry. Now scientists have figured out a way to get these tiny molecules to join forces and collaborate on real work on a macro scale.
Once the subject of fantastical stories, nanoscience is now changing the world as we know it.
A hydro-responsive thread can be used with sensors to monitor body functions.
Alonso Nichols, Tufts University
Flexible, easy to make, inexpensive, stretchable and simple to coat with nanomaterials, threads are also very commonly used by doctors already.
Some companies have used nano-titanium dioxide to make powdered sugar on donuts whiter.
Two new studies from Food Standards Australia and New Zealand show there's no evidence that nanoparticles in food present a health risk, but there's more research to be done.
What’s in the bottle is good for me, right?
Microscopic needle-like particles don't seem like something you'd want to feed a baby. Whether safe or not, the way we deal with nanoscale food additives leaves plenty of other questions.
Hidden tools are making the world a safer place.
From tiny robotic doctors repairing your body to the latest climate change-tackling tools, nanotechnology is fighting an invisible battle on our behalf.
The microprocessors on this wafer of silicon have transistors measuring in the nanometres.
As the components in electronic devices are shrinking to the nanoscale, even a single atom out of place can disrupt their function. But this also presents an opportunity to make them even better.
A new method for creating a form of graphene with carbon dioxide sucked from the air has been announced with misleading claims.
The beauty of stained glass – all down to electron oscillations.
The field of plasmonics has implications for integrated circuits, biosensors, other light-based technologies – even invisibility cloaks.
Graphene powder can be manufactured.
Dr Mohammad Choucair
There is much excitement about graphene, a material only a single carbon-atom thick, but finding ways to do something with it that's affordable have always been a challenge.
When a material is mostly nothing, you can do interesting things with it.
The Prime Minister’s Prizes for Science – awarded at Parliament House in Canberra tonight – recognise excellence in science and science teaching. This year, we asked four prizewinners to reflect on their…
