Companies pay almost $6,000 extra per year for each employee who smokes Posted: 03 Jun 2013 04:29 PM PDT A new study suggests that U.S. businesses pay almost $6,000 per year extra for each employee who smokes compared to the cost to employ a person who has never smoked cigarettes.

Fukushima-derived radioactivity in seafood poses minimal poses minimal health risk, experts say Posted: 03 Jun 2013 03:31 PM PDT In 2012, biologists reported that they had detected radioactivity in Pacific bluefin tuna swimming off the California coast. The source of the radioactivity was Japan's Fukushima Dai-ichi powerplants, which were damaged by the strong earthquake and subsequent tsunami on 11 March 2011 and released large quantities of radioactivity into the Pacific Ocean. The news prompted widespread media interest and speculation as to the possible risks to seafood consumers posed by the levels of radioactivity found in the tuna. New research shows the likely doses of radioactivity ingested by humans consuming the contaminated fish, even in large quantities, is comparable to, or less than, the radiological dosages associated with other commonly consumed foods, many medical treatments, air travel and other background sources.

Are smartphones disrupting your sleep? Posted: 03 Jun 2013 01:36 PM PDT Smartphones and tablets can make for sleep-disrupting bedfellows. One cause is believed to be the bright light-emitting diodes that allow the use of mobile devices in dimly lit rooms; the light exposure can interfere with melatonin, a hormone that helps control the natural sleep-wake cycle. But there may be a way to check your mobile device in bed and still get a good night's sleep. A new study suggests dimming the smartphone or tablet brightness settings and holding the device at least 14 inches from your face while using it will reduce its potential to interfere with melatonin and impede sleep.
