It is hard to believe that some cancers miraculously go away for good, but it does happen. Over 1,000 case studies document cancer sufferers who experienced spontaneous regression of their tumor. So why does this happen, and is it possible to exploit it to benefit cancer patients?

For parents, it's axiomatic that steering young children into sports is good for their overall health. But just like almost everything else, too much of a good thing can also backfire. Playing a sport too rigorously can produce devastating injuries for teens who are still developing, as can playing one sport exclusively year-round.

We've all stayed up too late to finish a project or study for an exam, depending on caffeine to keep us going. But according to a new study, that chemical assist won't work for more than a couple of days.

Patients who are too ill to eat have been fed by temporary tubes for many years. But, large numbers of nursing homes are now rejecting these tubes in favor of tubes that are implanted into the stomach, often leaving patients with no choice but to undergo surgery that they may not want, or need.

New sleeping recommendations have been released, and just in time to confirm what millions of Americans already knew: We are so sleep deprived. Yawn.

Nearly half of all Americans will receive a diagnosis of a mental health disorder in their lifetime. Yet at the same time the media continues to disproportionally associate mental illness with violent crime, despite that less then five percent of violence in the United States is attributable to mental illness.

With individuals afflicted with Kennedy's disease, muscle cells and motor neurons die over the years because they accumulate a protein that is mutated. Researchers have discovered that this protein has a self-protective mechanism through which the effects of the mutation are delayed.

The aftermath of the heparin crisis should put to rest any notions that there's a conspiracy to suppress a cure for cancer; to control your mind with fluoride; to hide a link between vaccines and autism; or to treat Americans as guinea pigs for GMOs. If there was any truth to those beliefs, somebody would have uncovered it by now.

One "chemical" that fear mongers take potshots at is antifreeze. Except, there are really two antifreeze chemicals. One is toxic, and to get harmed by the other you'd have to drink enough to kill a horse. Literally. Chemical haters use this to trick you. To learn how ...

Pregnant women are advised to avoid cat litter boxes — so they don't get infected with Toxoplasmosis gondii, which can cause birth defects. Recent research also suggests that this parasite may also be linked to neurodegenerative diseases such as Parkinson's and Alzheimer's.

Teen cigarette smoking has continued to decline, perhaps due in part to the fact that e-cigarette use has increased. But some public health officials continue to lump e-cigs with more dangerous types of tobacco use, such as hookahs. More discrimination would be good if we want to help teens protect their health.

1. Hillary or Donald? Who will be best for science? Science is a $120 billion a year constituency and health is even bigger. Despite that, it doesn't get a lot of notice in elections. Still, we care about what the future might bring because America leads the world in science output, we practically run the table in Nobel prizes, and we lead the world in adult science literacy. The next President could have a huge impact on that, especially given the funding stagnation of the recent administration.

We know what you're thinking: Another video of Ana Dolaskie chowing down a bag of potato chips— What's new? But she's doing it for the sake of science! And hearing the crunch of the chips could make you hungry too!

The term epigenetics is being thrown around by many who incorrectly believe "genes are our destiny" by deliberately misinterpreting data. What is epigenetics, really? And how much stock should we place on its importance?

It is with extreme skepticism toward modern art that I read a review on biological art, or "bioart," in the journal Trends in Biotechnology. The authors' goal was to discuss the history and relevance of this artistic sub-discipline to contemporary society. For me, this bioart ranges from awe-inspiring to mind-numbing stupidity.

In the two months since the CDC announced that Zika virus causes microcephaly, researchers have been working tirelessly to learn how it does. A recent study brings us one step closer by showing that the Zika virus can bind to, and replicate in, cells of human placentae. This type of insight will help design a drug that could block Zika from getting to the developing fetus.

It's common practice for your pharmacy to substitute a generic version of a drug for its brand counterpart. But another cost-saving policy is being considered: substituting an entirely different drug from the same class as what was prescribed. This is a terrible idea, as Dr. Robert Popovian explains.

Sugar consumption — especially in beverages — is blamed for many ailments such as obesity and Type 2 diabetes. Now we can add gallbladder cancer to the supposed list of links. But the study finding such a link was observational — no causal connection can be assumed.

Muhammad Ali has been lauded for his oratorical skill, his activism and certainly his boxing. Yet for decades it's been believed that even one of the greatest boxers could not beat back the head trauma that led to the Parkinson's disease he suffered from since the 1980s. Yet was it really boxing that caused it? We are inching closer to learning the truth, but some questions remain.

When most of us listen to music, we hear more or less the same thing. But not everyone. There are people who have extra-sensory abilities to hear what other cannot, and they're others who either can't, or can, but simply don't enjoy it.

Palliative care services are misunderstood by clinicians and patients alike. However, research has shown that early discussions and referral palliative care soon after diagnosis yield significantly better results with respect to expectations, quality of life, less aggressive interventions and even survival.

With the Olympics quickly approaching, some people planning to attend are starting to feel that the possibility of getting Zika virus is not worth the risk. The latest is the "Today" show's Savannah Guthrie, who is pregnant. But a new study says the risk of infection is very small, stating that just 16 new cases of Zika will emerge.

While obesity prevalence for adult men didn't change much between 2005 and 2014, for women it increased significantly. This is true especially in Black and Hispanic women — groups that must be targeted for greater prevention efforts.

Shell Canada has contributed 860,000 hectares of offshore rights in the waters of Baffin Bay to the Nature Conservancy of Canada.

In what is just one more example of fear-based marketing, a company is selling "natural chemical" bracelets that supposedly protect kids from mosquitoes. Not only is this not going to work, but the natural chemical is just as toxic as DEET — the insect repellant that the company takes great pains to note, is absent. If this was on "Jeopardy" we'd call out this firm accordingly.
