A new law that e-cigarette trade groups and public health experts uniformly support -- making sure nicotine liquid can't easily be ingested by kids -- was signed ad made official by President Obama.

Ketamine, a dangerous 1960s hallucinogenic, may have new life for treating major depression.

The next time you make your way to a chain restaurant for a quick fix, don't utter the words "fast food." The phrase is dying. Enter "fast casual" and "fast crafted." The food itself isn't going anywhere, but re-branding it is now necessary since it's become so unpopular. Here are some other foolishly-named products down through the years.

Would taxes on less-nutritious foods lead to better health? Or better purchasing patterns? In a recent study of food taxes vs. food subsidies, researchers found little to support that notion as both affect food shopping decision making.

If you think you've heard it all when it comes to food, think again. Recently, 36 restaurants in Xinhua, China were accused of cooking up their cuisine with poppy capsules, among other illegal substances, in an effort to make dishes more addictive, increase sales and entice customers to come back for more.

While the Zika virus from Central America is captivating the U.S. and many audiences around the world, another disease is creeping behind the curtains and across our southern border: Chagas disease. An average human case is transmitted by an infected "kissing bug," but the smootch it delivers is rather nasty.

The CDC has issued a new, unnecessary warning to women of childbearing age. Essentially, it tells them that if they're not using birth control, do not drink. At all. Not only does this seem unduly alarmist and hyper-precautionary, but it's also not firmly rooted in sound science.

The ABC News affiliate in Denver and The New American talked to Dr. Gil Ross about the Zika virus, and how a pesticide that hasn't been used in the United States for over 40 years might be the solution.

As far as information goes, once our wrists only carried time. Then came music, and recently, heart rates. But now a team of California researchers has developed a wearable wrist device that seeks to tell us about the body's inner workings by "drinking" sweat from our wrists and analyzing it.

Vitamin water is back. No, not the kind you drink, but rather the kind you bathe with. So wrap your head around ... the Vitamin C-infused shower head. Because the current shower that deploys only water is no longer good enough? Really? How have we managed all this time without this device?

In science, a product passes reasonable safety tests and is deemed safe until shown otherwise. To modern food activists, alleging food is unsafe is a mercenary tactic to sell new fads.

There have been several cases of sexually transmitted Zika virus. Will this be the exception or the norm? It's too soon to tell, but two other viruses provide us with some clues.

Itchy bedbug bites are hardly a thing of the past, since resistance to commonly-used pesticides is on the rise. Not only are the critters basically laughing at older chemicals, the resistance seems to be carrying over to newer ones as well. A precipitous rise in the bedbug population may be in our future.

The mosquito-borne Zika virus has been declared a global public health crisis by the World Health Organization, but the agency did not say how to effectively fight it. One way would be to allow widespread use of DDT, which eradicated that same mosquito during the 20th century.

Dr. Mehmet Oz, that oracle of televised medical wisdom, is at it once again. This time his misguided excursion beyond the scientific realm produced his suggestion that fluoridated water is harmful. In response, the American Council on Science and Health once again plainly states that there needs to a warning label on his show.

Three-dimensional bioprinting is offering science a real hope of creating organs needed for transplants. With about 75,000 patients waiting on any given day, and an average of 22 people dying daily while hoping to receive a transplant, the need is acute to say the least.

A South Korean court ruled that a plant worker's death from ovarian cancer can be causally attributed to exposure from the "carcinogens" formaldehyde and phenol. But there is no evidence that phenol is a carcinogen, and her duration and level of exposure are also not realistic causes of her fatal illness.

If a 30-year old has trouble accessing web-based accounts, imagine the challenges facing aging seniors, especially those with failing memories and assets like bank accounts and stock portfolios? What's more, they can forget when wills are prepared, which makes digital access for their loved ones essential.

For all the talk about the supposed benefits of supplementing one's diet with high-dose Vitamin D, recent clinical trials reveal that the practice fails to substantiate such claims. Not only is there lack of evidence that the vitamin prevents fractures, but the research suggests that it may contribute to them.

It'd be hard, if not impossible, to avoid eating genetically modified foods. By one means or another virtually all our crops grains, fruits and vegetables have been modified in this fashion. If you don't believe it, take a look at the earlier versions of some of our current foods.

The renewed campaign against Type-2 diabetes is in full force with the launch of a website that seeks to identify Americans who might become diabetic. But in a medical environment often plagued by over-diagnosis and over-prescription, is this new tool -- which could potentially impact more than 80 million people -- really necessary?

The development of antibiotics and other antimicrobial therapies is arguably the greatest achievement of modern medicine. However, overuse and misuse of antimicrobial therapy predictably leads to resistance in microorganisms.

In an effort to stop tax evaders, the federal government is cracking down on sales of illegal cigarettes. Yet contrary to popular opinion, the cigarette black market may actually benefit public health, especially in impoverished communities. That's hard to believe, you say? Here's how it could.

While politicians want compound pharmacies to put together approved drugs, the EPA didn't want two approved pesticides used together. A US Appeals Court asked why, and didn't like their answer.

The U.S. is facing drug shortages with increasing frequency. From intravenous fluids to chemotherapeutic agents for life-saving treatments, doctors, hospitals and healthcare personnel are increasingly burdened with the ethical dilemma of rationing drugs. Here's a closer look at this vexing situation.
