Anyone who has suffered through sleepless nights due to uncontrollable itching knows that not all itching is the same. New research at Washington University School of Medicine in St. Louis explains why. Working in mice, the scientists have shown that chronic itching, which can occur in many medical conditions, from eczema and psoriasis to kidney failure and […]

Researchers at the University of Illinois at Chicago have identified a protein expressed by human bone marrow stem cells that guides and stimulates the formation of blood vessels. Their findings, which could help improve the vascularization of engineered tissues, were reported online Oct. 12 in the Journal of Molecular and Cellular Cardiology. “Some stem cells actually […]
Scientists from the United States have been developing a technological feat that would drastically reduce the recovery time for people experiencing severe burns and wounds.
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.
There really can be ‘too much of a good thing’. Amounts calculated for one sitting consumption by a 150lb person.
Nature gives us some pretty amazing things, but sometimes we do one better.
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.
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.
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 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.
Genetics company 23andMe was just granted a patent on technology that allows you to design a child in the same way you might a car or a house. Is this really the future of baby-making? And if so, is this a good or bad development? Anthony dives deep into the patent for answers.
