...judgment have realized that we rely on emotions to make decisions about risk. We can't possibly mull over every new piece of data our brains collect, so our emotions give us shortcuts, helping us make split-second judgments about that information. The more uncertainty, the more shortcuts we use. This is a good thing. People who have suffered brain damage that removes emotions from their calculations cannot function. They can't make decisions, even simple ones. So we need our emotions to make sense of the world. But our emotions also can lead us astray - particularly when we encounter...
...Americans do it several times a day: talk on a cell phone. Seems harmless. But when you make and receive calls, your cell phone emits low levels of radio-frequency radiation - a fact that has fueled heated and ongoing scientific debate on the health risks of mobile-phone use...
...Sept. 9, the Environmental Working Group (EWG), a public-health advocacy, released a lengthy review of past research linking long-term or frequent cell-phone use with increased rates of brain tumors, migraines and kids' behavioral problems. For their part, the phone industry and the Federal Government say cell phones are safe. The "majority of studies published have failed to show an association between exposure to radio-frequency from a cell phone and health problems," states the U.S. Food and Drug Administration on its website. But concerns are high enough that the Senate on Sept. 14 held hearings...
Better, long-term research is needed - and it can't come from the cell-phone industry. (Some scientists have suggested levying a $1 surtax on phones to fund new studies.) For now, you can use a Bluetooth or wired headset or simply talk on your cell phone less to reduce the amount of radiation that bombards your skull. You can also choose a low-radiation cell phone; the EWG has created a searchable online database that ranks the radiation levels of more than 1,200 models. (Sorry, Apple fans, your iPhone ranks pretty high.) And finally, take a cue from...
...stickier than explaining Harvard places and objects is the quandary of whether to use real names of people. Gessen’s titular sad young men represent what he describes as three guys who are each similar in different ways to the author...
