Building the perfect lens with metamaterials
In principle a “perfect lens” could be created that opens up a brave new world of scientific investigation, particularly in nanotechnology and the biosciences.
The key requirement of these instruments is to devise a cunning way of getting around the diffraction limit, which restricts the resolution of images produced with optical light.
This film takes you to Imperial College London to investigate one promising route to a perfect lens that uses artificial structures known as metamaterials.

Is Recycling Worth the Effort?
We are always told how we should recycle what we use. But does it really make that much of a difference? Some think recycling is for greenies only. Truth is there are actually a lot of other benefits too.

Telescope to track space junk using youth radio station
Built to allow astronomers to look back in cosmic time, the Murchison Widefield Array (MWA), based in outback Western Australia, will also look into the future and help avert catastrophic collisions between satellites and space junk orbiting the Earth.
A research team using the MWA has predicted that FM radio waves transmitted from commercial radio stations can be reflected off space junk and detected by the MWA, allowing the junk to be monitored and tracked.
Publication: Tingay et al. in The Astronomical Journal 146, 103 “On the detection and tracking of space debris using the Murchison Widefield Array. I. Simulations and test observations demonstrate feasibility”
Gravity: How Do We Clean Up Space Junk?
Alfonso Cuarón’s film “Gravity” brings up a very interesting question - what do we do with all the debris flying above the Earth? Space junk is a huge headache for scientists, engineers, and astronauts. It makes space exploration incredibly dangerous when the tiniest object traveling at incredible speeds can cause catastrophic damage. Jonathan explores some really cool proposals companies have come up with to clear out space junk, from tractor beams to grappling hooks!

Light Can Draw on Liquid
Researchers have manufactured photo-chemically active polymers that can be dissolved in water or certain alcohols. When exposed to light, the polymer dissolves completely and leaves a clear form that is visible in the cloudy solution.

Slalom Kayak Race - Shooting Update (Science of Materials)
We’ve been having fun with Untamed Science lately. We’re shooting a new series on the “Physics of Materials” and what a better way than to show the differences in kayaks. Here is a short little video showing some behind the scenes stuff from my first slalom race. I think I have a long ways to go to become a pro at this!

MWA telescope detects FM radio bouncing off space junk
Commercial FM broadcast signals are transmitted into Space and bounce off satellites and pieces of space junk. The Murchison Widefield Array (MWA) radio telescope can detect the reflected signals and image the orbits of these objects.
