Anti-Radiation Drug, 5000x more effective than current drugs
The drug is based on single-walled carbon nanotubes, hollow cylinders of pure carbon that are about as wide as a strand of DNA. More than half of those who suffer acute radiation injury die within 30 days, not from the initial radioactive particles themselves but from the devastation they cause in the immune system.
Bulas' particles break down the universe
It was a world that transported him to a universe beyond our imagination: where stars like Arcturus flew towards us at two miles a second and where our entire solar system appears as a speck of dust. On the microscopic scale things got even weirder; here a colliding atom once split (in a process called quantum entanglement)
Researchers create 3-D structure using DNA-directed assembly
In 1996, scientists at IBM and Northwestern University used single-stranded DNA as if it were molecular Velcro to program the self-assembly of nanoparticles into simple structures.
