    Will Soda Taxes and Fast-Food Bans Fix Obesity?

    While government agencies, businesses, and private institutions are all looking for ways to battle the obesity crisis, no one has yet figured out successful interventions that both improve health and save money, and programs being implemented are often untested.

    Why Caffeinated Alcohol Drinks Are So Risky

    “Blackout in a can.” That’s what kids call the fruity caffeinated-alcohol drinks that offer a cheap, fast way to get drunk and party all night. As safety concerns grow, so does the pressure to pull these potent products from store shelves. Oklahoma, Washington, Utah, and Michigan recently banned the drinks. Beverage retailers in Indiana are lobbying their state to do the same; Pennsylvania has asked state-run liquor stores to voluntarily stop selling them. Meanwhile, pressure is mounting on the FDA to finish its yearlong investigation into the drinks’ safety.

    Obama's Web Troops Have Gone AWOL

    What happened to the Netroots? That’s what I’ve been wondering ever since the Republicans routed the Democrats last week. Two years ago, a lot of people—myself included—really believed that all those online activists who helped elect Barack Obama were going to stick around and support him as he pushed through a sweeping list of progressive measures.

    Why It's Hard to Do Marijuana Research

    Voters in several states said no to more-liberal marijuana laws. But for scientists, restrictive pot policy could be keeping them from better understanding how the drug works on our brains and bodies.

    The Biggest Questions About HRT Answered

    Almost no topic in modern medicine has been as controversial or confusing as hormone-replacement therapy. The issue got even more confusing last week thanks to a study published in The Journal of the American Medical Association and based on data collected for the ongoing federal Women’s Health Initiative (WHI) that found that women taking estrogen and progesterin had an increased risk of breast cancer. Here, the answers to the eight questions asked most often.

    What's Wrong With Silicon Valley Libertarianism?

    Qwiki: The Next Step in Search

    About 18 months ago, I took a trip to Buenos Aires. Naturally, I searched the Web for information on the city, but what I found didn’t feel natural at all. There were lists of links; spammy, dense blocks of text; and a hodgepodge of videos and advertising. It took so long to assemble key facts about the city, I almost missed my flight. Amid this frustrating experience, however, I also had a moment I’ll never forget. I realized that what the Web needs isn’t another search engine. It needs story, a quintessentially human way to experience information.

    Toning Footwear: Sound Science or Gimmick?

    The shoe market has recently been glutted with a new wave of "toner" sneakers promising a better body simply by walking. At first blush, these new kicks seem like the most magical footwear since Dorothy's ruby slippers. But consumers are right to ask whether the shoes are based on sound science or marketing gimmickry.

    Mobile Texting Could Change Face of Philanthropy

    Two hours after January’s earthquake struck Haiti, a texting donation campaign, “Text HAITI to 90999,” was up and running. After three days the effort had raised $5 million for the Red Cross, and “Text” and “90999” were in the top-10 trending topics on Twitter. Nine months later, more than $40 million has been donated by people sending as little as $5 to $10 from their cell phones.

    Why Masturbation Helps Procreation

    Since Christine “I’m Not a Witch” O’Donnell is campaigning for the U.S. Senate and not the directorship of the Kinsey Institute, maybe we should give her a pass when it comes to her views on sex and, specifically, masturbation. But that would be a mistake: the stakes are simply too high, going all the way up the very survival of our species. For while O’Donnell crusaded against masturbation in the mid-1990s, denouncing it as “toying” with the organs of procreation and generally undermining baby making, the facts are to the contrary.

    Is 'Living in Sin' Still Bad for Your Marriage?

    Moving in together before marriage used to be associated with a higher risk for divorce. But now, as more unmarried couples than ever before decide to live under the same roof, do they face the same fate? Sociologists think the calculus may have changed. Part of the difference stems from just who’s deciding to shack up.

    Why the FDA May Reverse Course on Avastin

    If the summer of 2009 was the season of “death panels,” as the debate over health-care reform exploded, this is the season of “17.5k dead women a year.” That’s the body count scaremongers are predicting if the Food and Drug Administration rescinds its provisional approval of the drug Avastin for metastatic breast cancer.

    The Sad Truth About the Facebook Movie

    The really interesting thing about "The Social Network" is that while much of the tale is invented, the story tells a larger truth about Silicon Valley’s get-rich-quick culture and the kind of people—like Facebook’s 26-year-old founder and CEO, Mark Zuckerberg—who thrive in this environment.
