Dads matter — according to science — and not just because they play a big role in your existence. Here's a little scoop on how dads help our mental and behavioral health!
 

The Centers for Disease Control calculated that, on an average day, 103 Americans die in car accidents, 121 commit suicide and 49 are homicide fatalities. But that's the average day. As it turns out people die differently on Monday than they do on Saturday.

Few chemicals evoke more of a visceral response than glyphosate, the active ingredient in Roundup. According to activists the herbicide causes cancer. A 2015 IARC monograph agreed, calling it ''probably carcinogenic to humans." But it did so without considering a key, conflicting study. Stranger still, the exonerating evidence came from the chairperson. What's going on?

Tans look healthy — even though they're not. A tan means sun exposure, which means an increased risk of skin cancer. But new research is pointing the way to getting the benefits of melanin, the tan-producing pigment,  without exposure to UV radiation. The new technique works in mice, so maybe it will be the answer for humans, too.

To understand the high cost of prescription medicines we should "follow the money." With apologies to Nobel Laureate Bob Dylan, it's time to "watch the river flow."

Edgar Allan Poe had a fascinating but strange mind, and perhaps he wasn't truly mad to think a raven was after him. Turns out, if you wrong a raven, it will shun you... Forevermore.

If we want the Environmental Protection Agency to protect Americans from true health hazards, it needs to be reformed so it stops inventing health scares.

Since every minute counts for heart-attack victims, getting automated external defibrillators to them faster has the potential to truly save lives. A Swedish study shows that dispatching GPS-enabled drones to stricken people where these devices aren't readily available is a feasible and efficient way to increase patient survivability.
 

America has about the highest proportion of overweight and obese on Earth, but the rest of the world is hot on our heels. A massive meta-analysis of global data indicates that between 1980 and 2015 the prevalence of obesity doubled in more than 70 countries.

People who commit suicide tend to have shorter telomeres and excess mitochondrial DNA. While these changes are not likely to be responsible for them committing suicide, they instead could serve as a biomarker for risk of suicide.
