Researchers have found that several moisturizers are linked to an increased skin cancer risk in hairless mice, but caution that there's no reason for people to panic. Mouse skin is very different from human skin, they say, and the mice also developed a very curable type of cancer called squamous cell carcinoma, not the more lethal melanoma.

Lead researcher Allan Conney says the team discovered the risk while testing a theory that caffeine could prevent skin cancer. "We sort of got into this by accident," Conney said in a telephone interview. "We wanted a safe cream that we could put the caffeine into" [Reuters].

Our world is awash with petro-chemicals. From plastics to pesticides they are integral to modern life. Wayne Ellwood argues that we are all paying the price for the release of these hazardous substances.

'Every time I come here my body gets sad and angry at the same time,' says Ron Plain. 'You can't put into words what it means to me.'

We've just tumbled out of Ron's jeep near the end of a three-hour tour of Sarnia, Ontario's 'chemical valley'. Ron calls it his 'toxic tour'. He's done it dozens of times so the pattern is easy and familiar. Sarnia is a gritty blue-collar community of 70,000 people at the top of the St Clair River, on the Canadian side, about a 100 kilometres north of Detroit. The river is wide and fast-flowing here, a natural link from Lake Huron, south to Lake Erie and east to Lake Ontario.

Of all the weirdness in the universe, the quantum mechanics phenomenon called "entanglement" may be the most mind-boggling. Physicists have long shaken their heads at the theory that two particles that become entangled will always and instantly mirror each other's properties, no matter how far they are separated, which seems to go against all other physical understanding. In the everyday world, objects can organize themselves in just a few ways. For example, two people can coordinate their actions by talking directly with each other, or they can both receive instructions from a third source…. But quantum mechanics allows for a third way to coordinate information [Nature News].
