Simple lifestyle interventions are a tempting target to stave off cognitive decline and Alzheimer's disease. Sadly, two new studies appearing in JAMA show no discernible benefit from exercise activity nor from omega-3 or vitamin supplementation.

First, the EPA bungled the mine disaster in Colorado, polluting a beloved river. Now, it's getting even tougher to believe its officials, when earlier this week the agency announced that an internal investigation of a separate matter cleared itself of wrongdoing.

A new trend among health care systems is posting patient evaluations of staff physicians, or "doctor report cards." This is a bad idea, as professional qualities of care, knowledge and compassion (much less outcomes) are not amenable to Yelp-like reviews as if doctors were personal computers on sale.

Bees die. A lot. They die in the winter, they die in the summer. Sometimes they die in one area, which is what happened in 2006. Why? Well, it could be stress. Or that beekeeping has become a fad, where amateurs are bungling their backyard hive. So there's mounting evidence that the so-called "Beepocalypse" is not to be Bee-lieved.

It appears that some Indiana school children may be forced to create a secret smuggling web. Does it involve drugs, or other contraband? No. They're doing it just to get through their midday meal. Do we want to raise a generation of students who worry they can't even trust their own lunch?

There's a new sugar substitute called allulose (aka psicose), with properties that could make it a very popular, non-caloric sweetener. But it must be manufactured. It'll be interesting to see how psicose will be received by the anti-sugar substitute psychos.

Congress tries to control drug prices and it blows up in their faces. How? Shortages of common drugs, and obscene price gouging for others. Unintended consequences? You bet, along with a few horrendously painful outcomes for patients.

Time to stop counting calories? Really? Doctors say some dietary changes are more important for reducing heart disease. But can t we do both?

A new study links long-term, continuous use of common painrelievers (NSAIDs and aspirin) to a reduced risk of colorectal cancer (CRC). This study does not prove a cause-and-effect benefit, and these drugs can cause bleeding, so discuss with your doctor.

Now that it's OK to eat fat again, we seem to need another dietary villain. Enter The Sugar Film, one Australian's attempt to blame sugar for his ills after he consumes way too much of the stuff. How convincing is it? Not very.

N.Y. Mets' star, David Wright, returned to the field Monday night and announced his recovery from spinal stenosis in the best possible way: by hitting a long home run in his first at-bat. The mystery of why he came down with this condition is unknown. Sadly, a new report shows that local steroid injections probably won't help people suffering from Wright's condition.

No, Virginia, you don't have to drink eight glasses of water every day to be healthy. This is a myth that's been handed down for generations. It wasn't true at the start, and it isn't true now. In fact, too much water can be deadly.

Is meat and dairy an addiction? A group of vegans believe that it is, and like with smoking, harm reduction and gradual cessation may be key to transitioning to this new diet.

Dairy cows have to be dehorned by farmers in a cruel fashion, but its necessary to protect other cows and the farmers that handle them. One scientists, however, is working on a solution: incorporating the genes of from a hornless cow into the regular dairy cow. The technique promises to reduce animal cruelty, but since its a GMO, advocates don't like it.

Would you pay a premium for a product that would prevent your family from getting the food-borne illnesses that sicken 48 million Americans and kill 3,000 more each year? And if it was endorsed by the USDA, the CDC and the WHO, wouldn't you find that safety appetizing?

Vegans are promoting the belief that cheese is somehow addictive. The vegans espousing that call eliminating everything going "cold Tofurky."

While Dr. Norman Borlaug's humanitarian efforts are so vast, sadly they are so little-known to the public and even to scientists. That's why we're once again calling attention to a short documentary film which highlights a lifetime of life-saving work and his fervent devotion to eliminating global starvation.

In today's "you never know what is around the corner" department, a surprising story says that beta-blockers heart drugs that are used to lower blood pressure and slow the heart may have another use. That would be reducing the toll of ovarian cancer, which is one of the hardest types to treat.

Dr. Phillipe Grandjean has a long and well-deserved reputation of being in the forefront of "toxic terror" campaigns. He has launched anxieties about all sorts of fish in our diets, but now he has become a devotee of warning nursing mothers about--of all things--potentially toxic chemicals in breast milk.

The U.S. isn t the only country with folks providing scatterbrained theories about what people should or shouldn t eat, and why. We have our Vani Hari (aka the Food Babe), and now it turns out that Britain has its own group of loopy ladies who are also out to lunch.

We usually think about young people as those who frequently go too far with alcohol. While that's true, we often overlook other demographics. A new study points out that 20 percent of senior citizens, those over the age of 65, are also hitting the sauce way too hard.

A long-standing controversy with oral hypoglycemic drugs is that, while they lower blood glucose levels, there is little or no evidence that they add years to a patient's life. So, lower glucose levels in type 2 patients have, in effect, been little more than a controversial marker of disease. Until now.

The real issue is that our culture has gotten intellectually lazy. All someone has to do is ask about funding and a giant swath of people will dismiss the work. It is not just the anti-GMO and anti-vaccine contingent, everyone does it...

A new study published in JAMA, focusing on a survey of 2,500 ninth graders, suggests that e-cigarettes might be a gateway to traditional tobacco smoking. But a closer look shows how the study falls short.

The ads are all over TV men suffering from low T or low testosterone can boost their levels and improve a variety of macho attributes by using one of several types of testosterone supplements. But according to the FDA, this may not be such a great idea.
