Diet Diary Doubles Weight Loss
Dieters who wrote down everything they ate had twice the weight loss of other people following the same diet. Karen Hopkin reports

Dear diary: Today I ate three carrot sticks while I fantasized about eating carrot cake. Alright, alright, I ate three pieces of carrot cake, and never once considered an actual carrot. How am I ever going to lose that last 10 pounds? Well, new research shows that keeping a diary—a food diary—can help. According to a study published in the August issue of the American Journal of Preventive Medicine*, people who write down everything they eat each day lose twice as much as those who don’t.

Nearly 1,700 people participated in the study. They were asked to follow a heart-healthy diet, full of fruits and veggies and low-fat or nonfat dairy. They attended weekly group sessions and were told to engage in moderate exercise for half-an-hour a day. After six months, nearly two-thirds of the participants had lost at least nine pounds. But the real surprise came from the food logs: those who simply kept track of what they consumed lost twice as much as those who failed to fess up. So next time you’re tempted by the clarion call of the carrot cake, stop to consider how it would look in your diary—not to mention on your hips.

—Karen Hopkin

Secrets of Bad Singing
A study finds that most people actually can carry a tune fairly well--and why those who can't just keep singing. Karen Hopkin reports, assisted by Mel F. Louis

On the June 30th podcast, you heard some bad singing. Clearly a lot of people think they can sing—just look at the enormous crowds that show up to audition for American Idol. But how many people can actually stay in key? [Sound of bad singing.]
Scientists think they have an answer, which they presented at a conference on acoustics in Paris on July 2nd. In the first part of the study, the researchers stopped people at random in a Montreal park and asking them to sing Quebec’s anthem. In that park, turns out 40 out of 42 people sounded as good as the pros. That percentage is surprisingly high. Which makes the two people who couldn’t sing especially interesting—why couldn’t they carry a tune? [More bad singing sound.]

The researchers repeated the experiment, this time asking people to sing Jingle Bells. They then tested the bad singers’ ability to listen to some music and identify the sour notes. They found that the off-pitch crooners fall into two classes. Those who simply can not hear that they’re hitting the wrong notes. And those who can tell, but keep singing anyway. [More bad singing sound.]
—Karen Hopkin, with Mel F. Louis

Bright Bugs Clue for Plant Medicinals
Natural toxins in plants can fight human diseases. Research shows that when looking for promising plants, a telltale clue is the presence of brightly colored insects. Christopher Intagliata reports

In the insect world, bright reds, oranges and yellows can be a warning: “Eat me at your own risk, pal.” Because colorful bugs can be toxic, they often get their chemical protection from nibbling poisonous plants. But these poisons can have a flip side for us—some fight cancer or tropical parasites that cause diseases like malaria.
The idea that colorful bugs can tip us off to disease-fighting plants isn’t new. But researchers at the Smithsonian Tropical Research Institute just backed it up with science, in the journal Frontiers in Ecology and the Environment.They chose ten plant species that kill parasites and cancer in lab tests, and ten species that look similar but do nothing. Then they headed into the Panamanian jungle to survey hundreds of these plants for beetles and caterpillars. Turns out, they found colorful bugs on almost all the toxic plants but less than half of the harmless plants. And black, brown and gray bugs didn’t have a preference—they ate indiscriminately. So modern-day shamans scouring the jungle for cancer-fighting drugs might just cut down on search time by keeping an eye out—for brightly colored bugs.
