Hybrids may be the coolest fuel savers, but??gas-gulping SUVs could be a lot more efficient too. The Union of Concerned Scientists has come up with a design that achieves 35% better fuel economy than the best-selling Ford Explorer. For only $760 more, that green SUV could be on the road. Combining the usual body-on-frame design into a lighter "unibody" would boost fuel economy as much as 8%. Add a sixth gear to the transmission, lower-friction lubricants and electronic valve controls, and you would be up another 17%. Even redesigning side mirrors to cut wind...
Ian McEwan is a very successful novelist, but??he hasn't let it go to his head.

Most of humanity probably won't read his new novel, Saturday (Doubleday; 289 pages), which arrives in stores next week. But the sizable part that does will gain definite advantages in the richness of its thinking about brain surgery, the war in Iraq, the psychic burden...
It seems hard to believe, but??it wasn't that long ago that the idea of birds evolving directly from dinosaurs seemed just a little flaky. Sure, they shared generally similar body plans--paleontologists have known that for more than a century--but that hardly constituted an airtight case. Over the past couple of decades, however, scientists have uncovered all sorts of detailed characteristics common to birds and dinosaurs: wishbones, swiveling wristbones and, most recently, proof that some dinosaurs sported feathers. There's behavioral evidence too. Some dinosaurs made nests and sat on them, and one four-winged, feathered...

...expected to remain relatively constant, aid to the permanently disabled, has more than doubled in the past ten years. The explanation: under state rules, heroin addicts are considered permanently disabled, a judgment with which it is difficult to argue. To get aid, the addict must register for treatment, but???catch-22?everyone knows that treatment is hard to get, and of questionable effectiveness. The money goes largely
