Drink Up: New Study Concludes Wine Can Offset Dementia

The health benefits of wine can sometimes be overstated by people who are a few glasses deep and slurring their words. Should you ever find yourself in a position to defend your moderate imbibing, you have supporting evidence: A new study says two glasses of wine daily can potentially reduce your risk of developing Alzheimer's.

The study, which appears in Scientific Reports, shows that wine has an effect on one's glymphatic function, or the way the brain removes toxins. To clear itself of damaging and accumulated proteins like tau and beta amyloid, which are often linked with dementia, the brain pumps in cerebral spinal fluid (CSF) to act as a flushing solution. All sorts of variables can influence the glymphatic system's operation, including trauma, stroke, and excessive alcohol intake.

But when researchers dosed the mice in the study with moderate alcohol—amounting to 2.6 drinks daily—the glymphatic system was more efficient, removing more waste and exhibiting less inflammation than the teetotaling control mice.

As is usually the case when it comes to booze, you can have too much of a good thing. When mice got the equivalent of 7.9 drinks daily, their glymphatic system grew sluggish until the overindulging was terminated.

"Studies have shown that low-to-moderate alcohol intake is associated with a lesser risk of dementia, while heavy drinking for many years confers an increased risk of cognitive decline," lead study author Maiken Nedergaard, of the University of Rochester Medical Center, said in a press statement. "This study may help explain why this occurs. Specifically, low doses of alcohol appear to improve overall brain health."

L’Oréal’s New Wearable Sensor Keeps Track of Your Daily UV Exposure

Anyone who has ever suffered a sunburn knows that too much exposure to UV radiation is bad for your skin. But in the moment, it can be hard to tell when you’ve gotten too much sun—especially during the winter, when you might not think you need sunscreen. (In reality, snow reflects up to 80 percent of the sun’s UV light, so you may end up getting hit with the same rays twice.) A new wearable sensor spotted by Wired aims to make understanding your sun exposure a whole lot easier.

L'Oréal’s new La Roche-Posay My Skin Track UV sensor pairs with a smartphone app to alert users when they’ve had high levels of UV exposure. Developed by L'Oréal’s Tech Incubator in collaboration with Northwestern University engineering professor John Rogers and Swiss designer Yves Béhar, the sensor measures UVA rays (which are associated with skin aging and skin cancer) and uses an algorithm to calculate UVB exposure (which is associated with sunburn and skin cancer).

At only half an inch tall and 1.3 inches long, the waterproof sensor is designed to be discreetly attached to your clothes, watchband, or sunglasses. The sensor's LED detector measures UV rays as sunlight passes through a small window in the device, then transfers the data to your phone via a near-field communication (the same technology in some hotel key cards). It stores the photons from the UV rays in a capacitor, eliminating the need for a battery.

Based on this data, the My Skin Track app can tell you how close you're getting to the maximum limit of UV exposure doctors recommend per day. It also provides updates about the air quality, pollen count, and humidity wherever you are at any given moment. Based on this information, as well as data about your specific skin type and skin tone, the app's Skin Advice feature will provide customized tips for keeping your skin healthy. It also recommends specific products—La Roche-Posay items can be bought directly through the app, should you desire.

The sensors are exclusively available through Apple stores. You can order one online for $59.95.

Massive Salmonella Outbreak Linked to Raw Turkey Just Days Before Thanksgiving

The U.S. has been in the midst of a salmonella outbreak for more than a year, with the bacteria contaminating everything from cereal to snack foods as well as raw poultry. Now health experts warn that your Thanksgiving dinner may put you at risk for infection. As ABC reports, salmonella has been traced back to a number of turkey products, and Consumer Reports is urging the USDA to name the compromised brands ahead of the holiday.

The drug-resistant strain of salmonella linked to the recent outbreak has been detected in samples taken from live turkeys, raw turkey products, and turkey pet food, according to the Centers for Disease Control and Prevention (CDC). Since November 5, 2017, 164 people in 35 states have contracted the infection from a variety of products.

While many of the items linked to the salmonella outbreak have been pulled from shelves, the potentially contaminated turkey brands have yet to be identified. In a news release, Consumer Reports urged the USDA to release this information in time for consumers to do their Thanksgiving shopping.

"The USDA should immediately make public which turkey producers, suppliers, and brands are involved in this outbreak—especially with Thanksgiving right around the corner," Jean Halloran, director of food policy initiatives for Consumers Union (the policy department of Consumer Reports), said in a statement. "This information could save lives and help ensure consumers take the precautions needed to prevent anyone in their home from getting sick."

Even if specific brands aren't flagged before November 22, the CDC isn't telling consumers to skip the turkey altogether. Instead, home cooks are encouraged to practice the same safety precautions they normally would when preparing poultry. To avoid salmonella poisoning, start with a clean work area and utensils and wash your hands and counter thoroughly before and after preparing the bird. But skip washing the bird itself, as this can actually do more to spread around harmful pathogens.

Cook your turkey until the meatiest part reaches an internal temperature of 165°F. And if you're looking for a way to make sure the juiciest parts of the turkey cook through without drying out your white meat, consider cooking the parts separately.
