Sandrine Ceurstemont, video editor Cheap 3D printers can now quickly make plastic replicas of almost anything, from an insect's wings to copies of their own parts. But now Amit Zoran and his team from the MIT Media Lab have used one to recreate the intricate design of a flute (see video above). They started by making a digital model of the instrument based on a metal flute but with adaptations to account for the new materials used, and the level of precision possible, with 3D printing.

10 Strange Things About The Universe - Top 10 Lists | Listverse Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely.

Gallery - Reflecting on a new generation of mirrors - Image 1 00:00 12 February 2009 Mathematician Andrew Hicks designs unusual mirrors that reflect wide panoramas or even show text the right way round Image 1 of 7 Non-reversing mirror This mirror does not produce a "mirror" image, making it possible to read reflected text normally. Hicks, a mathematician at Drexel University, Philadelphia, used computer algorithms to generate the mirror's bizarre surface, which curves and bends in different directions.
