A new study using PET scans on the brains of older individuals shows a three-fold higher risk of mild cognitive impairment (MCI) among those with elevated levels of amyloid-beta, a proteinaceous material associated with neurodegeneration. MCI is a known risk factor for Alzheimer's disease.

We're used to thinking that men typically drink more than women. That's still true but it may not continue to be so if current trends are an indication of future behaviors. Based on survey data, nearly half of all women reported consuming alcohol within the previous month, a finding which is up from 10 years earlier. Meanwhile, for men, tipping a drink, dipped.

Women with relatively severe PMS may be at higher risk of developing high blood pressure (HBP), or hypertension. It's not clear how such an interaction may occur. Premenstrual syndrome sufferers may be at especially high risk of developing HBP before age 40. Thiamine and riboflavin may reduce the increased risk.

Most fad diets do not work for everyone, regardless of what someone writing a book claims. So why is that the case? A new study seeks to create an algorithm to predict better results.

Amblyopia, or lazy eye, is a condition that affects roughly 3 percent of kids in the U.S. Traditional treatment methods use a patch or vision-blurring eye drops to intermittently block the stronger eye, forcing the weaker eye to work harder. But new FDA-approved programmable glasses that mimic these tactics are offering an intriguing treatment option.

When Turing Pharmaceuticals bought Impax Pharmaceuticals, the sole supplier of the antiparasitic drug Daraprim, and jacked up the price more than 50-fold, patients and doctors were furious. Enter a third company, which is now selling a similar pill for a $1, compared to Turin's which cost $750. Does this dollar deal make sense? Maybe, and here's why.

At long last, the FDA approved biotech salmon, AquaAdvantage, which is bred to grow to twice the size of other fish. But in contrast to every scientific study and advisory, the editorial board of The New York Times writes that the genetically-modified fish should be labelled. We take issue with that position.

Obese individuals have yet another reason to shed extra pounds -- this time to prevent knee cartilage degeneration. A recent study found that obese patients who lose at least 10 percent of their body weight can slow down the progression of cartilage damage and potentially avoid knee replacement surgery.

Metformin has long been the front runner of oral medications prescribed for glucose control in Type-2 diabetics. But could it also help adolescents with Type 1? Apparently not, as a recent JAMA study failed to find any statistically-significant benefit in improving blood sugar control.

Today is #GivingTuesday, and the American Council on Science and Health is excited to be a part!

A new drug for pertussis, or whooping cough, targets the bacteria's deadly toxin. It could be an important player in treating the infection, given that both vaccines and antibiotics are losing their effectiveness.

Since 1965, U.S. births by cesarean section have increased seven fold, from 4.5 percent then to 32.2 percent of all deliveries in 2014. While this significant trend does not appear to be increasing maternal or neonatal mortality, the issue of why have C-sections have become so popular remains up for debate.

Walnuts seem to be making their way into the news with increasing frequency. A recent study found that walnuts significantly aided diet quality, while helping the lining of the walls of blood vessels and improving total and LDL ("bad") cholesterol levels.

Your Thanksgiving turkey is a direct descendent of the dinosaur. Scientists have found that the turkey and the chicken have undergone the fewest genetic changes as compared with other birds to their avian ancestor, the dinosaur.

Is shopping a sport? A recent paper by academics attempts to make the case that it is for some people. They are not poor or buying 10 gallons of mayonniase because it's cheap, they are just determined to get the best deal on what they want.

The University of Colorado School of Medicine is out about $1,000,000 because they didn't want the distraction that came with one of their professors raising money - exactly the thing that professors are supposed to do.

Some technologies wow us simply because they are so cool. A good example is a case report in which interventional cardiologists were able to perform an angioplasty with the operator wearing a head-mounted Google Glass device.

The American College of Physicians has advised clinicians where possible to prescribe generic medications, rather than expensive brand name drugs. ACP also conducted an extensive review of 2,500 publications in an attempt to answer five important questions about the use of generic meds.

The sequence of events required to keep the human heart beating for an entire lifetime is executed over two billion times. A recent article discusses the novel approaches, based on stem cell technology and cellular reprogramming, to potentially develop cells that can mimic the heart s natural pacemaker.

A recent CDC report provides data that shows nearly 47 percent of Americans who have been diagnosed with high blood pressure are not adequately controlling the condition. Though concerning, it's an improvement from 1999, when roughly 68 percent had high blood pressure that was not treated.

The holy grail of diabetes research has long been finding a way to administer insulin by mouth. And that goal may have been reached by scientists at the University of California at Santa Barbara, who have developed a capsule that resists the acidic environment of the stomach.

Two studies show that fewer men have been screened for prostate cancer using the PSA test since 2012, when a federal panel advised against routine screenings. With doctors increasingly questioning the test's validity, that's a good thing. But the real key is whether reduction in PSA testing has led to a rise in late-stage or fatal prostate cancer.

Antibiotic resistance and the possibility of approaching the end of the antibiotic era sounds fairly apocalyptic. A recent study reveals a new gene, MCR-1, that allows for a common bug, Eschirichia coli, to become resistant to polymyxin antibiotics. These are the last line of defense against infections with E. coli. This has pandemic potential.

According to the WHO, cataracts are responsible for 51 percent of world blindness. While cataract surgery is not a new concept by any means, there has been new and promising ideas behind treatment options.

Some young adults have stop smoking those cancer sticks and are now moving onto marijuana, according to a recent study.
