Heart disease is the leading cause of death in women. To learn why, along with how best to prevent it and to clarify any misperceptions about the dynamic nature of the female cardiovascular system ... 

Does your blood type – specifically, your Rh factor (positive or negative) – matter in your daily life? Not in the slightest. But when pregnant your Rh status can matter, especially if it's negative.

Conventional wisdom suggests that occupations associated with low socioeconomic status – such as construction, extraction and maintenance jobs – would be linked to the greatest number of ALS and Parkinson's deaths because of workers' environmental exposures to chemicals. But the CDC found the opposite to be true.

Athletes classified as "moderately specialized" were found to be at a 50 percent greater risk, while those "who had a high specialization classification had an 85% higher incidence" of lower extremity injuries.

It's well known that menopause incurs many negative consequences, including hot flashes, bone loss and added weight in the abdominal area (visceral fat — the worst kind). Any of these can have negative health effects, and current treatment options such as drugs to prevent/treat osteoporosis don't do anything for added fat, or vice versa. But recent research in mice suggests that blocking the hormone FSH could greatly help.

Does race play a role in the care our veterans receive? This study sheds some light on where the differences may be found.

A recent report in the journal Lancet, titled "Dementia prevention, intervention, and care," raised the prospect that there might be evidence that older folks can improve both their hearing while reducing their risk of Alzheimer's. But it's with a heavy heart that we say that the hype far exceeded the knowledge.

A dose of science weirdness involving falling mice, a dishonest eatery that foolishly mocks chemistry ... and a truly stimulating coffee – if you get our drift.

Some medical diagnoses are like fad diets. Everyone you know has chronic Lyme disease or gluten intolerance, if not out-and-out celiac disease (whether a medical test confirms it or not). But many are just junk medicine, just as many fad diets are junk nutrition.

Fad diets never work. Stupid diets can make you ill. Here's a two-minute rant by Ana Dolaskie on eating raw chicken.

1. Dr. Julianna LeMieux and I were at the Cato Institute for the Dr. Ed Calabrese talk on the linear no-threshold model (LNT) used to set regulatory limits.
Members of our Board of Scientific Advisors, like Dr. Jerry Cutler and others, have long-considered LNT to be the Patient Zero of junk science used to create regulations. It basically says that particle 1 is as harmful as particle 1,000,000. Also mixed in the discussion is hormesis, a u-shaped curve in dose-response, which can also be controversial when misused by activists.

New research suggests that saffron – a spice used in some Asian, Indian and Mediterranean dishes – may have an intrinsic ability to fight cancer. But don't get too excited. Research on antioxidants suggests the same thing, but they fail in clinical trials.

Although some observational studies have suggested that vitamin D can help prevent upper respiratory ailments in adults, no such data substantiates that claim for children. A new study that compared low- and high-dose vitamin D with respect to such problems in kids found no effect at either level. Sorry, parents!

David Everette was simply walking to a store when making the absolute wrong decision during a fierce thunderstorm cost him his life. Instead of racing for shelter, the North Carolina resident took shelter under a tree. The tragic incident underscores the importance of knowing what to do – and what not to – when lightning is even remotely nearby.

Given how well women propagated the species despite all kinds of past health scares, should today's mothers panic about eating a piece of sushi? Well, yeah, though they needn't worry about coffee or BPA, despite litigation groups like Center for Science in the Public Interest long insisting those things are ruining families.

John McCain’s office released a statement from the Mayo Clinic Hospital in Phoenix, providing details of his Glioblastoma brain tumor. It was disclosed that the 80-year old senior Senator from Arizona was recovering from a surgical excision of a blood clot performed on July 14 that was discovered during a routine annual physical. 

In 2015, you were roughly 16 times more likely to get food poisoning from Chipotle than you were to be attacked by a shark. We can't remove all the sharks from the ocean, but we can remove pathogens from our food. Chipotle should have focused on that, instead of GMOs.

What's happened to Chipotle during the past two years is too bad to be true. The food chain has given a whole bunch of people food poisoning, especially from norovirus. But the virus rarely strikes in the summer, so how did it end up hitting the same chain again? Could this be a conspiracy? Is Chipotle actually making the virus? Put on your tin foil hats and read this. 

When it comes to survival, birds are not birdbrains. Some learn to avoid roads, while others thrive near them (with the exception of the Cross Bronx Expressway). A study out of Australia explains how and why this occurs. 

If you believe the hype that the Organic Consumers Association puts out, you believe that organic foods are better for you than the conventionally raised variety. And you likely also believe that animals raised in line with organic principles are also treated more humanely. Oops!

The recent Alzheimers Association’s International Conference might explain an uptick in mainstream media reports about the disease. And they have a common thread: the reports are based on clinical abstracts rather than the actual papers or datasets. So do these media reports serve to clarify – or confuse?

In 2012, the hepatitis C universe changed forever when Gilead's Sovaldi was approved. Finally, there was an excellent drug that could eliminate the infection almost all the time. But some strains of HCV are tougher than others to treat. But now, Gilead strikes again.

McDonald's. Dell. Chrysler. Rolls-Royce. Sears. Trump. All are companies that bear the names of their founders. Does that matter? One would think not, but new research from Duke University claims that eponymous companies are more successful than others.

Two major league teams recently raised sun-protection awareness with their fans, many of whom often sit for hours exposed to the strong summer sun. The Philadelphia Phillies and Atlanta Braves are spreading the word (and the sunblock), having installed free sunscreen dispensers at the ballpark, all part of MLB's Play Sun Smart campaign. 

New legislation might be the key to bringing opposing political parties together in this Pacific Northwest state. The state penalizes drivers — which bicycle commuters cheered. But now officials have created a special tax on cyclists, too, and that has united the left and right in mutual outrage.
