Change Your Hair Colour By Etching Nano-Patterns Into Each Strand

In a weirdly serious bit of hair research, engineers have figured out how to change hair colour without an ounce of hair dye. The only catch? You need a focused ion beam. Colour is in the eye of the beholder after all. When microscope spirals and hyperbola are etched into strands of hair with a focused ion beam, those tiny ridges work together to diffract light. Certain wavelengths are cancelled out, others amplified and you get a whole new colour. No hair dye needed.


Carbon Nanotube Transistors That Will Save Moore's Law Are Coming In 2020

Our world of amazingly tiny electronics is about to get even tinier. After a decade of research, IBM says it will bring carbon nanotube transistors to market by 2020. The company is now readying the technology to take over from silicon transistors, and that opens up a lot of exciting doors.


These Robotic Sperm Could Change The Way In-Vitro Fertilisation Works

A team of Dutch engineers just published the details of a curious new invention: tiny robotic sperm that can be controlled with a weak magnetic field. Like real sperm, these so-called MagnetoSperm flip their tails to swim towards their target. Unlike real sperm, they’re made of metal-coated polymer.


The World's Smallest Nanomotor Spins As Fast As A Jet Engine

A team of engineers at the University of Texas at Austin recently created the world’s smallest, fastest nanomotor. Designed to power microscopic machines that could deliver medicine or fight cancer, this thing will fit inside of a human cell. And boy can it purr.


Scientists Built An Impossibly Small Engine But Don't Know How It Works

It must be fun to invent something. One day it does not exist, and the next day it exists. But how would you feel if you didn’t exactly know why your new invention worked? The minds behind this all-new microscopic engine could tell you.


Scientists Put Tiny Sound-Powered Motors Inside Living Cells

Brain-bender alert! For the first time ever, scientists have managed to insert nanomotors into living cells. Once inside, the gold, rocket-shaped motors were propelled with ultrasonic waves and steered with magnets. Because we now live in a scene from Fantastic Voyage.


How Bioelectronics Promise A Future Cure For Cancer

When you think of cyborgs becoming a reality, you probably picture Arnold Schwarzenegger’s glowing red eye from Terminator or the steely, tight-lipped stare of Robocop. But the future where man and machine converge won’t just be built with nuts and bolts. It will be built with biology.


Stretchy New Sensors Can Be Woven Into Clothes That 'Feel'

Imagine if your sweater was actually one big computer that responded to being stretched, pressed, or adjusted. That cyborg-inspired future could now be a reality thanks to a team of scientists that has used nanowires to create a new wearable, multifunctional sensor.


Laser Holograms As Thin As A Hair Could Be The Future Of High-Res

Holograms are cool enough on their own, but amazing things happen when you make them incredibly small. A team of Army-funded scientists from Purdue did just that with the development of tiny holograms — smaller than the width of a human hair! — made by shining lasers through a metasurface. This could change display technology forever.


Gold Nanoparticles Give Plastic Skin Life-Like Senses

Human skin may very well be one of the world’s most impressive sensor arrays. Able to detect temperature, pressure, touch and pain simultaneously, your skin’s sensory receptors feed you a constant data stream about the environment around you. Now, researchers have given much of that sensing ability to plastic e-skin.
