    You might have paid more attention to cell division in biology class had you seen this timelapse video from filmmaker Francis Chee (below). It shows the cell division of an egg from Rana temporaria (the common frog) in such astonishing detail that it looks like a digital effect. Starting with just four cells, it divides into seemingly millions more in around 33 hours, a time that's compressed to 23 seconds in Chee's video.

    So apparently, virtually all existing official limits for radiation emitted by mobiles (FCC, we're looking at you) are based on the assumption that the dangerous effects of that radiation are caused by heating of the brain. Pretty big assumption, eh? A new study by Israel's Weizmann Institute of Science suggest that some "non-thermal" forces are at play, though, noting that chemicals involved in brain cell division were affected in tests on rats after just 10 minutes of exposure to cellphone radiation. Improper cell division goes hand in hand with cancer, so the finding is a rather alarming one. Of course, you know the drill: for every study that suggests phones are dangerous, we can certainly dredge up one that says they aren't -- just be forewarned that a cool brain isn't necessarily a healthy one.[Via CNET]
