Nanoparticles in baby formula: should parents be worried?

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.
A new development could mean vastly increase data transfer over optical fibre cables. Shutterstock

Twisted light could dramatically boost internet speeds

The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.

Electronics are getting small, and that is causing big problems

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.

Using lasers to cut a diamond apart atom by atom

One of great challenges of the 21st century has been to develop ways to manipulate matter on smaller and smaller dimensions. As the great physicist Richard Feynman noted in his famous 1959 lecture, “There’s…
Is that a nano-bot in your guns, or are you just pleased to see me? jcoterhals

Show us your (carbon nanotube artificial) muscles!

The idea of doctors deploying miniscule robots in your body to diagnose and treat medical conditions is closer to reality today with the development of artificial muscles small and strong enough to push…
The new ‘epidermal’ electronic systems conform to the surface of the skin and may provide a range of healthcare and non-healthcare related functions. John A. Rogers

Game-changing’ printed tattoos may replace hefty medical monitors

Scientists have invented new stick-on ‘tattoos’ that track human heart, brain wave and muscle activity and could one day replace cumbersome medical monitors. Known as an epidermal electronic system (EES…
Researchers hope to use piezoelectricity – which is generated by mechanical pressure such as fingers tapping a screen or blood pressure – to power gadgets like iPads or pacemakers. Flickr

Could blood pressure power pacemakers in future?

That tangled collection of chargers could one day be obsolete, as Australian researchers report a breakthrough that brings us closer to a world where gadgets are recharged every time you press them. Scientists…

Nanotechnology delivers big dose of anti-cancer drugs to tumours

Scientists have developed tiny particles capable of taking large doses of anti-cancer drugs right to a tumour’s doorstep, opening the way to a new generation of more effective treatments. Nanotechnology…
