'Man With the Golden Arm' Retires From Donating Blood After Saving More Than 2 Million Babies

One of the most prolific blood donors in the world has completed his final blood drive. Nicknamed "The Man With the Golden Arm," James Harrison of Australia has given blood more than 1100 times in the last 60 years, Mashable reports.

He said he would have kept donating, too, had it not been for the Australian Red Cross Blood Service's rule that donors can only give blood up until their 81st birthday.

Harrison's blood carries a rare antibody that has helped save the babies of more than 2 million Australian women. The antibody is used to create a medication called Anti-D, which helps fight rhesus disease, a condition in which antibodies in a pregnant woman's blood attack her unborn baby's blood cells. Prior to 1967, when the Anti-D program was rolled out in Australia, many babies died from the disease. Harrison just happened to be the first Anti-D donor in the country.

After undergoing chest surgery at age 14, Harrison pledged to thank his anonymous blood donors by paying it forward. He has also donated plasma, which is similar to the process of donating blood, except the plasma is separated out and the blood is returned to the donor's body.

In recognition of his service, Harrison received the Medal of the Order of Australia (OAM) in 1999 and was also added to the Guinness Book of World Records in 2003 for having donated the most blood. However, according to online records, this record has since been broken—a show of dedication that Harrison no doubt approves of.

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.
