This Headset Uses Sound To Navigate Blind People Through Cities

Using substitute senses for visually impaired people isn’t a new idea — even putting aids into hi-tech glasses isn’t new. But this project takes things a step further, piping in relevant information straight into the wearer’s skull.


How Do People Estimate Crowd Sizes?

Although the task of determining how many people attend something as large as say, a political rally or a protest may seem like a daunting, almost impossible undertaking to do with any accuracy, with some basic information, it’s actually not that difficult to get reasonably accurate results.


Fast-Acting Nuclear Reactor Will Power Through Plutonium

Even the latest generation of nuclear power reactors can only harvest about five per cent of the energy stored in their radioactive fuel supplies, and the toxic leftovers must then be buried deep underground to slowly decay over hundreds of thousands of years. But thanks to a new breed of sodium-cooled pool reactor, we may soon be able to draw nearly 100 times more energy from nuclear fuels, while slashing their half-lives by two orders of magnitude.


Why Is Left-Handedness Rare?

Being a lefty myself, I’m always keen to read and watch more about the reasons why humans aren’t split down the middle when it comes to hand dominance. Turns out science doesn’t have a specific answer yet, but that doesn’t mean we can’t hear what the popular theories are and explanations as to how our brains, animals and even the universe, has its preferences for right and left.


Scratching An Itch Does Indeed Just Make It Itch More

Well that’s settled. You know how your mum always told you not to scratch that mosquito bite because that just makes it itch more? Your mum was right, and now we have the science to prove it.


Sunlight Reflecting Off The Hydrocarbon Seas Of Saturn's Moon, Titan

This Algae Farm Eats Pollution From The Highway Below It

A highway overpass is the last place most of us would think to install a farm. But algae, that wonderful little ecological miracle, is different. Since it consumes sunlight and CO2 and spits out oxygen, places with high emissions are actually the perfect growing area. Which is why this overpass in France has its own algae farm.


Don't Panic: The Ozone Hole's Holding Steady

Despite research suggesting that the ozone layer is still being chewed apart, NASA’s most recent study of the Antarctic ozone hole reveals it isn’t getting any larger.


Egg Freezing: How We Reschedule Nature With Liquid Nitrogen

Egg freezing has recently jumped from an expensive and rare medical procedure to a recognised backup plan for women pushing up against the biological cutoff for conception. But what exactly are you signing up for?


5 Scientifically Proven Reasons It's Better To Be Single

Crying into a pint of ice cream alone on Valentine’s Day? Talking through your problems with your cat? Taking your mum to your office holiday party? Hardly. These are absurd stereotypes of singledom — not the reality.
