A Cure for Baldness Might Come From the Deep Fryer at McDonald's

Science has thus far failed sufferers of baldness. Aside from expensive surgeries that transplant individual hair grafts from the back to the front of the head and medications that can slow the progression of loss, there is no cure. But researchers may be closer than ever, thanks to a common food preparation additive found in many fast food menu items.

A study recently published in the journal Biomaterials detailed work performed by Yokohama National University that shows promising results for regenerative therapy—a method for growing hair follicles in enough quantity to repopulate bald or balding areas. The Yokohama scientists were able to produce hair-follicle germs, or HFGs, cells that direct the development of follicles, in the lab. Once injected into the backs of mice, hair follicles and hair shaft regeneration followed: Tufts of hair began sprouting on the mice within days.

Professor Junji Fukuda said in a statement that the key to mass production of HFGs was having a substrate to rest on while being prepared and then injected into the mice. They chose dimethylpolysiloxane, a type of silicone found in commercial frying oils to prevent them from frothing.

The next step will be to see if the approach is as effective in humans. "This simple method is very robust and promising,” Fukuda said. “We hope that this technique will improve human hair regenerative therapy to treat hair loss such as androgenic alopecia. In fact, we have preliminary data that suggests human HFG formation using human keratinocytes [skin] and dermal papilla cells."

How to Choose the Best Watermelon

Buying a watermelon is an experience one can grow to resent. The 92 percent moisture content of Citrullus lanatus means you're basically buying a giant ball of water. On the plus side, they're delicious and packed with enough vitamin C and D to keep you from getting scurvy.

But how to select the best of the batch? Food blogger Emma Christensen over at kitchn recently offered some advice, and it involves a little weight-training. When you examine watermelons in the produce section of your local grocery, you want to look for the heaviest one for its size. The denser the fruit, the more juice it has. That's when it's at its most ripe.

Next, check the underside of the watermelon for the "splotch." That's the yellow patch the watermelon develops by resting on the ground. If it's a creamy yellow, it's also a good indicator of being ripe.

Finally, give the underside a little smack—not aggressive enough to draw attention from grocery workers, but enough so that you can determine whether the watermelon sounds hollow. If it does, that's good. If it sounds dull, like you're hitting a solid brick of material, it's overripe; put the watermelon down and slowly back away from it.

If you're not confident in your watermelon evaluation abilities, there's another option: Local farmers markets typically have only choice product available, so any watermelon you pick up is likely to be a winner. You can also ask the merchant to pick one out for you. Pay attention to what he's doing and then try to emulate it the next time you're forced to choose your own produce.

The CDC Makes It Official: Public Pools Are Disgusting

Every summer, warm weather sends people across the country looking for a cool refuge in public pools, hotel pools, spas, and other water-based destinations. Before you take the plunge, you may want to heed the advice of the Centers for Disease Control and Prevention (CDC). Jumping into a publicly-populated pool could be like bathing in someone else’s diarrhea, as Men’s Health reports.

The health agency revealed its findings in their Mortality and Morbidity Report, which explains why pools are ground zero for bacteria. Between 2000 and 2014, the CDC traced 493 outbreaks and over 27,000 cases of illness that could be connected to exposure to a public pool. The primary culprit was Cryptosporidium, a parasite found in feces that causes intestinal distress. The determined little bugs can survive for up to seven days after encountering the CDC’s recommended levels of one to three parts per million (PPM) of free chlorine. Even if the pool is being cleaned and maintained properly, Cryptosporidium can idle long enough to infect someone else. The report also indicated that Legionella (which causes Legionnaire’s disease) and Pseudomonas (responsible for ear infections and folliculitis) were found in some of the pools.

The problem is likely the result of swimmers entering the pool while suffering from an upset stomach and leaving trace fecal matter behind. The CDC recommends that you not enter a public pool if you feel unwell, that you ask for a pool inspection report if you’re concerned about the hygiene of the facility, and that you absolutely not swallow any water. The agency also recommends that any pool owner who has experienced a “diarrheal incident” in their water opt for hyperchlorination to kill bacteria.
