The ability to carry an electric current without resistance had been known only in metals. Now superconductivity is seen in organic crystals made up of Rat molecules in zigzag stacks
The conjunction of the hang glider and the small engine has brought into being the "air recreational vehicle." A typical craft carries 200 pounds and cruises at 50 miles per hour
The radiation emitted by carbon monoxide molecules in clouds of gas and dust where new stars are forming discloses masses of gas moving outward at high velocity in opposed directions
They are enzymes that convert rings of DNA from one topological form to another, linking them and even tying them in knots. The enzymes may take part in genetic replication and transcription
Local perturbations of blood flow interact with the repetitive hydraulic stress generated 100,000 times a day by the heart to give rise to these balloonlike dilatations of an artery wall
