...cosmos-unpopular though they may be-that accommodate Freedman's age estimates. The same cannot be said for Lauer and Postman's detection of large-scale motions across the universe. Most scientists are betting that their observation is just plain wrong, but they haven't yet been able to pinpoint why. And both Lauer and Postman admit that the effect may wash out as they collect more data from deeper in space...
...Motorola's ambitious Iridium satellite project is ever completed, prospectively in 1998, virtually no place on earth will be out of range. Satellites are also making possible commercial use of the Pentagon- developed global positioning system, which was employed by soldiers using handheld monitors during the Gulf War to pinpoint their location in the desert. Private-boat owners have been using GPS to fix their position at sea for the past decade...
...also blame Ronn Tomassoni (you never win blaming individuals--the team as a whole stunk Saturday night, and to pinpoint any guilt on the aforementioned skaters is fruitless and ill-intentioned--but after watching a game like that, how can a self-respecting hockey critic not lash out at someone?), belatedly, for only Saturday getting back to the lines which were working so well for him during the glory days of mid-January after dabbling with some changes during what has become a 2-5-0 February swoon...
...discoveries like the one at the Chauvet cave, and more intensive study of existing sites, are constantly giving archaeologists more information to work with. Also, dating techniques are becoming more refined. It used to be that scientists needed to test a large sample of paint to pinpoint its age. And, says anthropologist Margaret Conkey, "no one was willing to scrape a bison's rump off the wall." Now it takes only a tiny sample. French prehistory expert Arlette Leroi-Gourhan estimates dates by using pollen particles preserved on cave floors...
...declining among men in industrialized countries. The French study shows the concentration of sperm dropped by 2 percent per year -- from 89 million per milliliter of ejaculate in 1973 to 60 million in 1992. A sperm count of under 20 million per milliliter indicates infertility. The researchers couldn't pinpoint a reason for the decline. "That's the real concern," says Time science writer Christine Gorman. "That there may be a continuing decline and nobody knows...
