Starting in middle age, the brains of obese people show startling differences as compared to those of normal weight, according to an analysis of fMRI images. White matter tissue connects regions of the brain and allows for information to be communicated between those regions.

Now that Zika has hit the United States, people will be deciding which, if any, mosquito repellents to use. You can have something that is "natural," or something that works. But not both.

Parasitism evolved at least 223 times, far more than the previous estimate of 60. It arose more times in certain phyla (e.g., arthropods, nematodes, flatworms, and mollusks) than in others. Today, about half of all animal species are parasitic.

Bayer's Belt insecticide, which was given conditional approval by the Environmental Protection Agency in 2008, has seen its registration pulled. Though labeled for use in almonds, pistachios, walnuts and various vegetable crops in 49 states, it wasn't used much.

Beverages sweetened with fructose, and High Fructose Corn Syrup, have often been blamed for causing or exacerbating cardiometabolic ills. But a new randomized, controlled study presents data that doesn't support this hypothesis.

The New York Attorney General has issued a cease-and-desist order on hucksters using fraudulent marketing to claim they can protect against Zika transmission. Unsurprisingly, these woo claims cater to the mindset that believes all chemicals are bad and some natural approach is better.

Seeking entry into the annals of Perceived Threats That Makes Parenting Needlessly More Frightening, we now have a new "study" claiming that kids playing within enclosed, inflatable, trampoline-like enclosures in warmer climates are potentially at risk of dying from heat stroke. "Researchers" please stop scaring parents.

Despite what eugenics proponents thought -- and their population control descendants still think now -- more people actually lead to more innovation. A new study makes the case again that, when stressed, human ingenuity is likely to win out, even in the short term.

Over-prescription of antibiotics for non-bacterial illnesses contributes to the overuse of these drugs and to antibiotic resistance by the bacteria — a real threat to human health. Some preliminary research suggests that testing for CRP might help decrease the rate of overprescription.

Krypton and xenon serve practical and important purposes. But harvesting them from the air is energy intensive, as it requires a temperature of -300 degrees F. So chemists constructed a molecular sieve that easily separates the noble gases at room temperature.
