...idea behind solar sailing is simple. Although light is made of massless particles called photons, such ephemeral things exert real pressure, especially when they flow from so close a source as the sun. Attach a sail of lightweight Mylar or other material to a spacecraft, set it up in the path of that outrushing energy, and you ought to be able to move in almost any direction...
...alcohol consumption--about a drink a day--can lower the risk of heart disease. Now researchers say the risk is reduced even further in men who carry a gene that slows the rate at which alcohol is metabolized. The longer alcohol stays in the bloodstream, the more it can exert such beneficial effects as raising levels of good, HDL cholesterol. Who has the gene? Mostly white guys; 1 in 6 is thought to carry...

The ordeal revealed how little power--or even moral suasion--university students really can exert...
Drugs are molecular saboteurs. They exert their curative effects by gumming up the works of key proteins in the body. The compounds with the fewest side effects are the ones that drop their monkey wrenches selectively, slotting seamlessly into grooves on the surfaces of their target proteins--and leaving other proteins untouched...

The compounds with the fewest side-effects are the ones that drop their monkey wrenches selectively, slotting into grooves on the surface of their target proteins-and no other proteins-as snugly as feet fit into socks...
