• Are children today really suffering nature deficit disorder (TM)?

  …7;t have television to keep them indoors, they also didn’t have child labor laws. The result was that children who once might have been at work at age 4 in a field were now at work at age 3 or 4 in a factory, putting in 12 or so hours a day before stepping out into the coal-smoked, animal-dung-scented air of the city.  Child labor wasn’t something confined to Industrial Revolution Britain, and it continues today, both for agriculture…

• Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

  …molecules themselves break down into a surprisingly small number of building blocks.

• Dr. Oz is worried about your fillings

  …much mercury is safe, then? According to the EPA, 0.1 micrograms of mercury per kilogram of body weight per day is safe.  For an adult who weighs around 150 pounds, that’s about 7 micrograms.  A 6-ounce can of tuna has about 20 micrograms of mercury, about 3 times the safe amount per day.  Scientists do have real concerns that mercury in tuna and other fatty fish might present a health hazard.
