A month back we discussed an article in GQ on the alarmist side of the cellphone-radiation question. Now reader pgn674 passes along a PopSci feature article looking at the current state of cellphone radiation research. It profiles people who claim to be electro-hypersensitive, "who are reluctant to subject themselves to hours in an electronics-laden facility" for studies. The limited research on that condition is still showing that sufferers, in blind tests, are unable to detect radiation at levels better than chance. The article also touches on the relationship of non-ionizing radiation to cancer. The conclusion is that while it seems unlikely high-frequency fields in consumer devices directly cause cancer, they might promote it, and might also indirectly cause other health deficits beyond simply heating nearby tissue — though one skeptical researcher cautions, "The gap between a biological effect and an adverse health effect is a big one."

The New York Times reports that stone tools discovered on the Greek island of Crete, and reported last month at an academic conference, are strong evidence for rethinking the maritime capabilities of early humans. The researchers who found the tools (hand-axes, cleavers, and scrapers) estimate them to be at least 130,000 years old; if they're right, humans have been traveling long distances at sea (Crete is 200 miles from the northern African coastline) for at least several tens of thousands of years longer than earlier believed.

Especially when creating Web sites intended for technical audiences, wouldn't it be best to end support for obsoleted browsers? Would this not provide additional incentives to upgrade? Recently I and my colleagues had to decide whether it was worth our time to try to support anything before IE8, and in the end we decided to redirect any IE6/7 user-agent to a separate page explaining that the site is not accessible with IE 6 or 7. This was easy once we saw from our analytics that fewer than 5% of visitors to the site were using IE at all. Have you had to make a choice like this? If so, what was your decision and what was the reasoning behind it?"
