Mice Regain Their Sense of Smell After New Stem Cell Therapy

Smells, like the tangy scent of the ocean or the acrid odour of smoke, are powerful cues that shape our memories and warn us of imminent threats. But for approximately 12 per cent of Americans over the age of 40, this crucial sense is significantly reduced or absent altogether. While scientists are still working to understand the causes behind this impairment, researchers at the University of Miami Miller School of Medicine have developed a method for restoring olfaction in mice through the use of stem cells.

How Do You Hear Without ‘Ears’?

History’s littered with lost ears: Van Gogh’s, Evander Holyfield’s, that ear Kyle MacLachlan finds in a field in Blue Velvet, etc. Or maybe ears is the wrong word. The weird little flesh-whorls that jut out from the sides of most of our heads are just small components of a much larger, delicately interconnected system. Remove part of that system with a razor-blade upon learning that your brother is getting married, and you risk seriously compromising it. Read More >>

How Our Bodies Sense the World is Misunderstood

Perhaps one of the first things you learned in kindergarten was that you had five senses: sight, taste, smell, hearing, and touch. But the actual number is probably way more than that, maybe in the 30s. And there’s a whole lot we don’t know about the senses that we do have. Read More >>

The Brains of Blind People Really Are Wired to Enhance Other Senses

It’s often said that the loss of one sense improves the others. New research shows the dramatic extent to which this is true in blind people, and how their brains make new connections to boost hearing, smell, touch — and even cognitive functions such as memory and language. Read More >>

We May Soon Have a Colour Wheel for Smell

Whenever you say a colour name, you’re referring to specific properties of light waves. Sounds work the same way, but with properties of compression waves. But what about smell? With all of the different scented chemicals out there and their complex interactions, it’s been impossible to create a simple scale to describe the odours or noses detect. Read More >>

Brain Implant Allows Paralysed Man to Feel Objects With a Prosthetic Limb

Researchers from the University of Pittsburgh and UPMC have developed a system that’s enabling a man with quadriplegia to experience the sensation of touch through a robotic arm that he controls with his brain. Read More >>

Students Hacked a Chip to Give Your Smartphone a Sense of Touch

Project Soli, which debuted at Google I/O in 2015, is a tiny chip that uses radar to detect discreet hand and finger motions. It was designed as a unique way to interact with mobile devices, but students at the University of St. Andrews found a way to use the simple chip to give electronics an actual sense of touch.

This Bionic Finger Restores Amputees’ Sense of Touch

A prototype bionic fingertip that allows the wearer to feel texture has been demonstrated by researchers, giving hope to the victims of amputation that robots may one day be of some actual use and not just the willing sexual playthings of the super-rich. Read More >>

Meet the Guy Who Smells Things for a Living for NASA

George Aldrich has been working with NASA for nearly 40 years doing one job: he smells things that are about to go to space. Seriously. Aldrich uses his nose to its full potential, sniffing everything around him to give NASA a report on what is allowed to go to space and what is not. Read More >>

Hearing Trick Convinces People Their Arms are Made of Stone

If your arm falls asleep for a while, it can sort of feel like it's made of rubber. But how do you make your arm feel like it's made of marble? According to Italian researchers, all you need is the sound of a hammer tapping stone. And some psychological trickery. Read More >>

Crazy Brain Implants Give Cyborg Lab Rats a Sixth Sense and Lets Them “Touch” Light

It's not every day that science and crazy brain implants lead to the generation of what is essentially a new sense, but it is that day today. Scientists from Duke University have found a way to make rats "feel" invisible infrared light and someday that same tech could give sight to the blind, or give us humans extras senses for fun.

What Colour Means to Blind People

Tommy Edison, the wonderful blind film critic who once showed us how he used an iPhone, has a new video describing something nearly impossible for blind people to understand: colour. What's great is that even though Edison doesn't understand the concept of colour, colours still have meaning to him. Watch him describe what red, blue, orange, black and white. It's awesome to see colour from such a completely different perspective. [YouTube via Laughing Squid] Read More >>
