In The Future, Spider Silk May Help Grow Your Replacement Heart

There’s been a lot of talk lately about how spider silk is this crazy wonder material that may soon find its way into everything from electronics to ultra-strong fabrics. Now, there’s another reason to be excited about spider silk: doctors might one day use the stuff to grow you a new heart.


Build The Ultimate Playlist To Improve Your Workout

It feels like listening to music while we exercise helps pump us up. But is there scientific backing to that claim, and how can you build the ultimate workout playlist? Giz explains…


The Quest To Re-Invent Photosynthesis Just Got More Colourful

Green may be the Plant Kingdom’s colour of choice, but it doesn’t have to be that way. In fact, it takes only a little chemical tuning to turn chlorophyll — the light-absorbing pigment that colours plants green — blue, red, orange, or any other hue under the sun.


For 50 Years Now, The US Has Had A Nuclear Reactor Orbiting In Space

Exactly half a century ago this week, a rocket shot off from the California coast. It carried the US’ first and only (known) space nuclear reactor, SNAP-10A, which has been circling the Earth ever since and will continue to circle for another 3000 years.


The Subzero Lab Where Scientists Recreate Avalanches In A Box 

Avalanches are powerful forces of nature, but they’re also the result of millions of tiny snowflakes bonded — or not bonded — together just so. Looking at avalanches falling down mountains can only tell you so much. At Montana State University’s “subzero lab”, scientists are studying how avalanches happen by recreating them flake by flake.


The Super-Massive Black Hole At Our Galaxy's Centre Is Great At Killing Stars

We don’t have to worry about the gigantic black hole at the centre of the Milky Way Galaxy — the scale of its machinations take place over millions of years. There is no doubt however that it is a powerful entity, one NASA recently discovered has the ability to snuff out entire stars with a blast of X-ray “wind”.


To Feed The World, We May Need To Hack Photosynthesis

One of the biggest challenges of the 21st century will be figuring out how to feed our rising global population. Now, some scientists are making the radical claim that growing more food won’t be enough — we literally need to hack photosynthesis.


Ancient, Predatory 'Lobster' Is An Ancestor To All Modern Arthropods

More than 250 million years before the first dinosaur, the most fearsome killers on Earth may have been lobsters. Yawunik kootenayi, a common ancestor to spiders, prawns and butterflies, was a predatory “lobster-like” creature that ruled the seas half a billion years ago.


A New Type Of Dyson Sphere May Be Nearly Impossible To Detect

Over fifty years ago, physicist Freeman Dyson proposed an awesome, if slightly insane, idea: That an advanced alien civilisation might construct a massive, energy-harvesting sphere around its star, and bunk up inside.


How A Virus Can Make Water Boil Faster

Here are some things that won’t make water boil faster: watching the pot, adding salt. And here’s something that does: nano-structures made from plant viruses, which subtly alter the physical properties of bubbling water.
