...observatory contains an 84-foot-diameter radio-telescape antenna that scans 640 million microwave-radio channels every 20 seconds as part of the Search for Extraterrestrial Intelligence (SETI) program. After the National Aeronautics and Space Administration (NASA) canceled SETI two years ago, private donors stepped in to keep the project alive. So if Earthlings are ever contacted by advanced aliens, both Harvards--the university and the town--will be, literally, the first to hear...

...hang up--yet. A preliminary study on 250,000 people finds no evidence that CELLULAR PHONES--notably the kind that have the antenna near the head, exposing users to microwaves--increase the risk of early death. Long-term studies are still needed...
...tragedy could have been averted if the U.S. Air Force had deployed one of its AN/TRN-26 Tactical Air Navigation systems there. The unit can offer detailed guidance to as many as 100 planes at once. Just the size of a desk and equipped with a 10-ft.-high antenna, the system is so portable it can be set up in only four hours. The Air Force has 43 of these units, which it routinely deploys to under-equipped airports. Four are in use: in Jordan, in Hungary, in the Bosnian town of Tuzla and at Camp David. Where...
...lured me into programming directed at non-American listeners deeply intrigued by all things American, including the vagaries of American English. For 35 years I listened, lately with a magnificent solid-state receiver I rescued one graduation day from a curbside trash barrel and refitted with a long copper antenna, realizing that my hour-a-day rowboat restoration projects proceed best when the world whispers in my boatshop...
