Moving on to February...

I reported on a new study ranking antidepressant drugs for the Los Angeles Times. Researchers compiled data from more than 100 clinical trials and concluded that two antidepressants -- Zoloft and Lexapro -- bested the rest. Another study found that antidepressants were largely equivalent in their therapeutic effect. More damning is a third study that used internal FDA documents to prove that published studies exaggerate the benefits of antidepressants by publishing only those trials with positive results. The take home message (and my favorite quote, thanks to UCLA psychiatrist Lon Schneider): "They may be comparing a relatively ineffective drug with another relatively ineffective drug."

In Nature (access limited to subscribers), I profiled ecologist Simon Lewis, who has studied tropical forests in Africa and thinks that they absorb and store more carbon dioxide than has ever been realized -- enough to affect atmospheric concentrations of the greenhouse gas. In a recent study, Lewis used data collected by the forest service of a number of African countries to monitor the growth of forest trees over four decades.

Hi Jill,

I arrived at your blog through one of your comments over at Renegade Writer.

Thought I'd drop by and say Hello!

Interesting reads here, I'll come back again!
