With health insurance costs having gone up for many Americans by 300 percent since the implementation of the Affordable Care Act, there is concern about ways to contain costs.

No one is willing to contain costs when it comes to children, a new study shows. In America's sue-and-settle culture, the big cost for medicine was not drugs or malpractice insurance, it was "defensive" medicine; running tests doctors know patients don't need, or providing a treatment that won't help, because they have to check off every box to prevent lawyers waiting to sue for malpractice.

Though there is some evidence that a ketogenic diet can help people with epilepsy, the 'food as medicine' industry has instead made huge leaps into a lot of claims based on suspect evidence.

While biologists will often note that there are a lot of food myths - turkey will make you sleepy, a child will run around like a maniac if they eat sugar - new ones are promoted just as fast, like that various diets significantly influence mental health and wellbeing. That is the issue; science may find one thing but surveys pretend to be just as valid, using claims of statistical significance that may be meaningless.

Poplars have become popular for use in products like paper, pallets, plywood, furniture frames - even as a biofuel - because they grow quickly.

But being natural doesn't mean being good for the environment. Poplars are a natural source of isoprene, which negatively affects regional air quality and can lead to higher levels of atmospheric aerosol production, more ozone in the air and longer methane life. Ozone and methane are n the category of greenhouse gases, and ozone is also listed as a respiratory irritant.

With the recent legalization of cannabis edibles in Canada, physicians may be inclined to recommend them in much the same way they do homeopathy or naturopathy. But unlike those placebos, which should not be recommended because it's a government subsidy for fraud, there are health risks for cannabis edibles, and media doesn't give it much attention.

"Although edibles are commonly viewed as a safer and more desirable alternative to smoked or vaped cannabis, physicians and the public should be aware of several risks related to the use of cannabis edibles," write Drs. Jasleen Grewal and Lawrence Loh from the University of Toronto, Toronto, Ontario.

Some people can experience a rash or sensitivity to some cosmetics while most people are fine. It isn't that modern cosmetics are bad, regardless what alternative companies and their trade groups like Campaign for Safe Cosmetics claim, it's nature. Botanical extracts sold as "natural" chemicals in cosmetics cause the same issue.

Though the development of agriculture 10,000 years ago is what made humans the apex predator, a new analysis reveals that the stage was set long before farming became science. 

Excavations at Border Cave in the Lebombo Mountains, on the border of KwaZulu-Natal Province, South Africa, and Swaziland, show that someone was cooking starchy Hypoxis angustifolia rhizomes plants, such as the Yellow Star flower, 170,000 years ago. It also suggests they probably used wooden sticks to extract plants from the ground.
