I am not making any of this stuff up. Science is totally fucking amazing.
From the May 2003 issue of R&D:
- Evident Technologies in Troy, NY is producing a kilogram of semiconducting nanocrystals every week. They are perfect crystals approximately 3 to 10 nanometers in size, meaning they are just slightly bigger than atoms and just smaller than bulk matter.
- A square chip slightly less than two inches on a side can now analyze the reaction of up to 400 genes to a specific substance in about two hours. The chip is produced by Infineon and MetriGenix.
- A group at U Chicago successfully measured the angular momentum of rings of light: optical vortices that are created by holographic optical tweezers. A HOT uses strongly focused, computer generated holograms to suspend microscopic particles in three dimensions - in theory, they could rotate a ring of spheres when the optical vortices are projected onto them, making them into a microscopic motor driven by light.
- Scientists at the U of Rochester have slowed light to 127 mph by shining it through a ruby 2 cm in diameter.
