Next Monday is World Malaria Day, and DDT will surely be in the news. The usual parade of opinion pieces calling for a revival of DDT spraying to control malaria (as though it ever stopped) will be on display.

You'll likely also read that the World Health Organization (WHO) has raised fresh concerns about its safety, and you may even hear that the Stockholm Convention has endorsed its continued use. Let me try to explain what's going on.

Today we are one step closer to protecting kids in this country — and around the globe — from persistent chemicals.

A group of senators proposed a new law this week to revamp our 35-year-old system of managing toxic chemicals. Our friends in Washington tell us this version of the bill is stronger than the attempt that stalled in Congress last year. How very refreshing to have good news coming out of DC!

Tomorrow morning, as you pour milk into your kids’ cereal bowls or buy a latte to get you going, take a moment to think about the dairy and other family farmers who will be braving gusty winds off Lake Michigan to converge on the steps of the Chicago Mercantile Exchange. These farmers are demanding an end to the price fixing and speculation by traders that has bankrupted thousands of family farmers across the U.S., while spurring food crises worldwide.

In an apparent, and failed, attempt at self-defense, honey bees are sealing off pesticide-laced pollen.

U.S. entomologists published a study two years ago that described a newly observed phenomenon in honey bees, now known as entombed pollen: food stores sealed off by bees after being deposited in the hive. That pollen was much higher in pesticide residues than any other pollen stored in the hive, and correspondingly had no detectable bacteria or fungi. Hives with entombed pollen were more than twice as likely to collapse later in the season than hives without it.
