When faced with a possible ailment, do you ever scour the internet for a diagnosis before referring to your doctor? And by that point, your symptoms have snowballed into a full blown self-diagnosis of cancer that not even your doctor can treat? If so, you might be a cyberchondriac…
All of the 2013 Nobel prizes have been announced! This year’s prizes went to people doing amazing work, but not everyone can be a winner. Trace looks at who won, who was snubbed, and which deserving scientists from the past never took home a medal.
Alzheimer’s researchers have announced two major breakthroughs in the past week. The first, via the University of Florida, is a test which uses the smell of peanut butter to detect the early signs of the disease — a cheap and simple idea which could help thousands of people. The second is from the University of Leicester, where scientists have discovered a chemical which, in mice, completely stops degeneration of brain tissue.
Scientific American editor Mark Fischetti explains how the leaves of deciduous trees perform their annual chameleon act, changing from various shades of green to hues of bronze, orange and brilliant red.
Heart racing, palms sweating, labored breathing? No, you’re not having a heart attack — it’s stage fright! If speaking in public makes you feel like you’re fighting for your life, you’re not alone. But the better you understand your body’s reaction, the more likely you are to overcome it. Mikael Cho advises how to trick your brain and steal the show.
It’s the go-to website for information on just about anything. But is the info on Wikipedia worth it’s weight in megabytes? Trace has the answer and tells us about a new plan to up the accuracy of some of its most popular pages.
Salt dissolves in water; oil does not. But why? You can think of that glass of water as a big, bumpin’ dance party where the water molecules are always switching dance partners — and they’d much rather dance with a salt ion. John Pollard explains how two chemistry principles, energetics and entropy, rule the dance floor.
For the past 800,000 years, there has always been ice in the Arctic Ocean. But now climate change is causing this ice to melt at an unprecedented rate, with some people predicting that the region’s waters could be completely ice-free as early as 2016. And as the ice melts, energy companies are moving in to try and drill for some of the world’s last untapped oil and gas reserves — the very fossil fuels that caused the ice to melt in the first place.
By any and all measures, Einstein was a genius. But what made him so different from any other person? Turns out his brain was wired in a very different way! Anthony takes a look inside to show you the ways in which Einstein’s brain was both different and similar to yours.
Magnetism seems like a pretty magical phenomenon. Rocks that attract or repel each other at a distance – that’s really cool – and electric current in a wire interacts in the same way. What’s even more amazing is how it works.
Ever wonder how ballet dancers can spin and spin and spin, but never seem to get dizzy? Neuroplasticity, that’s how! Anthony explains how it works, and how you can use your brain in the same way.
You’ve probably heard people say that they were so angry that they saw red. Or maybe you’ve noticed that the sleekest, curviest sports cars are usually scarlet-colored. So why would this one color come to represent such a wide-ranging duality, everything from eroticism and courage to and anger and brutality? And do bulls really respond to the color red.
A good night’s sleep might do more for you than just clear your head, it help you to be a stronger, less fearful person! Guest host Annie Gaus explains how the process works.
A team from Rice University have successfully created carbyne, a form of carbon bond that resembles diamond, but is 40 times stronger. The material was first theorised in the 1960s, but until now no-one has successfully created it, with some scientists even predicting it would be impossible to synthesise in ‘real world’ conditions. The team from Rice managed to create, and stabilise, the material at room temperature. It’s thought it could have uses in micro-mechanics and incredibly strong, light-weight fabrics.
It’s one of the more popular myths out there: We only use 10% of our brain’s power. Watch as Anthony finally puts this myth to rest.
