Back from maternity leave, Ana Dolaskie shares her thoughts on why most resolutions fail, and key factors in the ones that succeed.

Flu season is ramping up and it will be nearing its peak in a month or two. Unfortunately, what we've learned so far is that H3N2 is the predominant circulating strain. What that tells us, using previous flu seasons dominated by that strain as a guide, is that we're probably in for a rough ride.

Advertising of tobacco products on TV and radio has been verboten since 1971 to reduce the appeal of such products — especially to kids.

We spend over $73 billion annually on state lotteries. What is that all about?

Lawyers are routinely required to solve problems that they themselves created. If something like this were to occur in any other area of life, it would be called racketeering. So beware, science: a lawsuit-happy nation turns its eyes to you.

Whether it involves closing your eyes, drinking a hot beverage by the mug or basking in the warmth of dry heat, these activities are among a handful of easy ways to improve your health in the coming year (as well as those to come). 

Two decades ago Africa seemed like a lost cause. AIDS was unrelentingly decimating the continent and there was little cause for optimism. But life could not be more different now.

But what's not fully known is whether full moons – and the attention they possibly draw away from a motorcyclist's main safety task – are the cause of the higher incidence of fatal accidents. And during so-called "supermoons" researchers found that motorcycle deaths occurred 32 percent more frequently.

ACSH is in the business of promoting evidence-based science and debunking junk science. That rubs some people the wrong way.
