Something that looks very pretty when set to gentle acoustic guitars, apparently. In this video, a fuel droplet is set ablaze then quickly extinguished. Flames are spherical in low gravity since warm, buoyant air can’t rise to propel them. Thirty seconds later, a bright afterglow formed by a backlit vapour cloud spreads throughout the combustion […]
From Professor Gillian Griffiths: Cells of the immune system protect the body against pathogens. If cells in our bodies are infected by viruses, or become cancerous, then killer cells of the immune system identify and destroy the affected cells. Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or […]

Yes, it’s been around for a while, but it’s now taking off like a whirlwind – with everything from 3D remote control aeroplanes to opening a whole new range of sculptural artistry – and it seems like the Star Trek […]
Expedition 30 astronaut Don Pettit uses knitting needles and water droplets to demonstrate physics in space through ‘Science off the Sphere.’ This is part of the first video in a series for a partnership between NASA and the American Physical Society to share unique videos from the International Space Station with students, educators and science […]

After chasing it for more than two years I was finally rewarded with two displays of Aurora Australis (Southern lights) within a week visible from Mornington peninsula, not far from Melbourne.

It seems that this bat fly, found in […]
Underwater filmmaker Mike deGruy describes his wonderful nerdy path to exploring Earth’s final frontier. He’s a good example of how you don’t have to have a PhD to be a sexy geek, getting in arms races with octopi, and observing an eco-system discovered only 33 years ago! He also, of course, covers how irresponsible human […]
Okay, everyone. Don’t panic. It’s just a foot-long prawn thing pulled from miles and miles under the New Zealand sea. It’s not a big deal, it’s not a OH MY GOD IT’S LOOKING AT ME. …These tiny animals don’t often grow more than 1cm in length, except the Supergiant variety of course, which can exceed […]
