Roughly 200 million people contract the malarial parasite annually, and in 2013 malaria was the cause of 500,000 deaths worldwide. According to a recent study, a new genetic engineering technique is showing great promise in eliminating the mosquitos that carry the deadly disease.

Could a genetic engineer create a genome for the next Tom Brady in vitro? No, because there is no "QB intelligence" gene or "athletic anticipation" gene that a biologist could edit into an embryo, like there is for eye color.

College students are talking about universities divesting from fossil fuel investments -- and universities are pretending to listen. But while students leave school after a few years, endowments need to remain. So how can that work?

Yesterday at 1 PM Eastern, the ABC News Medical Unit created a social media event to talk about supplements. Along with the American Council on Science and Health, participants included the National Institutes of Health, Stanford University and others.

According to research published in JAMA Pediatrics, young men who have sex with men (YMSM) with detectable viral load levels are more likely to engage in condomless anal sex, and sex with an HIV negative partner, in comparison to YMSM with undetectable viral load levels.

A new report details adverse effects of high-exposures to "green tea polyphenols" on reproduction and development in fruit flies, after exposing their larvae to those substances. But the authors suggest that these same compounds can do the same thing to humans. Another case of "endocrine disruption" or junk science nonsense? Can you guess what we think?

A new study purports to link levels of chemical exposures to reduced response levels to bacille Calmette-Guerin vaccine in infants. The authors fail to note that simply measuring two chemicals and finding some impairment in some function does not mean that the chemicals caused it.

It's been a very bad year for Chipotle. The tex-mex fast food chain made itself look foolish by trying to riding the anti-GM train, while at the same time still using ingredients from GM crops (as if it matters). Then things got worse: three separate outbreaks of food poisoning, each caused by a different bug.

Organic food purveyors point out that organic already is non-GMO, while a non-GMO food is not necessarily organic. For the rest of us, it s basically a tempest in a teapot, except the teapot is the source of a huge amount of dough.

A new study of 51 e-cigarette liquids found the presence of detectable levels of three known lung toxicants in the large majority of the liquids. These substances are found in flavored e-liquids. Given their known risk, at least from occupational inhalation, they should be removed from these products.

A new, large study seems to link children with severe allergies to increased cardiovascular risk -- which include higher blood pressure, higher levels of cholesterol and obesity. The relative risks are significant, but the absolute numbers say it's not an emergency. But taking a closer look at the connection wouldn't hurt.

A new pro-vaccine ad campaign in Australia targets the secret anti-science demographic known as "Whole Foods shoppers."

What, if anything, makes suicidal people different from others? Is it environmental factors, such as losing a job or loved one? Or differences in brain structure or function that make people respond to such negative events by taking their own lives? A new study attempts to answer these and other related questions.

In August, Jimmy Carter was diagnosed with melanoma in his liver and brain. These lesions were addressed directly, he was put on Keytruda and now the former president is in remission. But since this new drug costs about $150,000 per year, we ask: Shouldn't we be talking about this?

On Dec. 10, 1990, Connie Chung generated a shock wave of fear over silicone breast implants. The impact of a TV report by the former CBS News reporter was instantaneous and powerful, producing a new low in one-sided, fear-mongering journalism. Yet today, it remains in the pantheon of all false-science reporting ever perpetrated on the American public.

Trained first responders need to stick to interrupted rescue breathing when performing CPR, as opposed to chest compressions only. According to the largest study of its kind, continuous chest compressions did not offer a better chance of survival, when compared to interrupted chest pumping for performing rescue breathing.

Despite improvements in treatment, mortality still remains unacceptably high in patients diagnosed with heart failure (HF). A recent study provides data that show a new drug on the market improves survival by one and a half to two years. It has potential to be the new cornerstone in HF treatment.

A new study in the journal Pediatrics shows that the Back-to-Sleep campaign, designed to reduce Sudden Infant Death Syndrome, is working. And as it turns out, the effort is also producing even more evidence that vaccines are safe.

A recent study says that survival rates for women with Stage IV breast cancer, in which the tumor has spread to lymph nodes to other regions of the body, has improved. Researchers found a significant link between those who received initial treatment with surgery, and improved survival rates.

Obesity is still rising among young adults, despite more than a decade of public awareness campaigns and other efforts to get people to control their weight. And as of recently, women have overtaken men in the obesity department. Researchers now say that being overweight during early adulthood may put one at greater risk of cardiac death.

Gilead researchers say they are unblinding the ongoing drug trial of Zydelig. The reason is that its leukemia drug was working so well, it should be made available to patients in the trial who were receiving standard treatment without the drug.

If you've been tracking efforts to combat the Hepatitis C virus, you know that 2015 has been a year full of advances and hope for the future. First, there was FDA's approval of the treatment Viekira Pax, and recently California researchers have unearthed diagnostic gold with their latest screening process.

A new treatment option for HIV, in the form of an injectable, may be on the horizon. The company ViiV Healthcare has found that its anti-retroviral treatment, or ART, has rates of efficacy comparable to oral multi-drug therapy.

ACSH and ABC News team up to answer questions about supplements on social media.

A recent Huffington Post op-ed by a female MD demanded "the truth" about mammograms, so that women could best help themselves. Well, there's no truth yet: the data continue to be evaluated and medical societies continue to make the best guesses they can. So, women should learn what they can and discuss the options with their physician.
