Fat Freezing Could Be the New Botox

Decades ago, cosmetic enhancement entered a new and lucrative era with the emergence of Botox, a botulinum toxin that paralyzes muscles to erase visible signs of aging.

In 2017, Botox is still as popular as ever. And now, a new process that addresses a different portion of the cosmetic surgery industry is quickly gaining ground—one that can freeze and kill off fat cells without injections or anesthesia. It’s been trademarked by one company as CoolSculpting, and those concerned about areas of unwanted fat believe it's the next big thing in cosmetic enhancement.

In a huge industry vote of confidence, pharmaceutical company Allergan Plc agreed to pay $2.48 billion this week for Zeltiq, the company behind CoolSculpting. Also known as "body contouring," medical professionals take an instrument and place it over fatty tissue for approximately 35 to 60 minutes (treatment length will vary by procedure). Freezing temperatures attack the fat cells, up to 20 percent of which die off and are then eliminated by the body within weeks.

Because the procedure is non-invasive and doesn’t require the downtime of a surgical intervention like a tummy tuck or liposuction, patients are usually under no restrictions and can resume normal activity quickly. It’s typically used for the abdominal area and under the buttocks.

According to Bloomberg, CoolSculpting and similar efforts are catching on because the patient can pay in cash, eliminating insurance hassles—cosmetic intervention isn’t usually covered—and practitioners can collect up to $4000 per treatment. If patients are happy with the results, they’re likely to return for more, or opt for further refinement with Botox and other methods.

Allergan is betting CoolSculpting will be a huge portion of the body contouring market that's expected to grow to $10.5 billion by 2020. And they should know: Allergan also owns Botox.

Not Sure About Your Tap Water? Here's How to Test for Contaminants

In the wake of Flint, Michigan's water crisis, you may have begun to wonder: Is my tap water safe? How would I know? To put your mind at ease—or just to satisfy your scientific curiosity—you can find out exactly what's in your municipal water pretty easily, as Popular Science reports. Depending on where you live, it might even be free.

A new water quality test called Tap Score, launched on Kickstarter in June 2017, helps you test for the most common household water contaminants for $120 per kit. You just need to take a few samples, mail them to the lab, and you'll get the results back in 10 days, telling you about lead levels, copper and cadmium content, arsenic, and other common hazardous materials that can make their way into water via pipes or wells. If you're mostly worried about lead, you can get a $40 test that only tells you about the lead and copper content of your water.

In New York State, a free lead-testing program will send you a test kit on request that allows you to send off samples of your water to a state-certified lab for processing, no purchase required. A few weeks later, you'll get a letter with the results, telling you what kind of lead levels were found in your water. This option is great if you live in New York, but if your state doesn't offer free testing (or only offers it to specific locations, like schools), there are other budget-friendly ways to test, too.

While mailing samples of your water off to a certified lab is the most accurate way to test your water, you can do it entirely at home with inexpensive strip tests that will only set you back $10 to $15. These tests aren't as sensitive as lab versions, and they don't test for as many contaminants, but they can tell you roughly whether you should be concerned about high levels of toxic metals like lead. The strip tests will only give you positive or negative readings, though, whereas the EPA and other official agencies test for the concentration of contaminants (the parts-per-billion) to determine the safety of a water source. If you're truly concerned with what's in your water, you should probably stick to sending your samples off to a professional, since you'll get a more detailed report of the results from a lab than from a colored strip.

In the future, there will likely be an even quicker way to test for lead and other metals—one that hooks up to your smartphone. Gitanjali Rao, an 11-year-old from Colorado, won the 2017 Young Scientist Challenge by inventing Tethys, a faster lead-testing device than what's currently on the market. With Tethys, instead of waiting for a lab, you can get results instantly. It's not commercially available yet, though, so for now, we'll have to stick with mail-away options.

Bill Gates is Spending $100 Million to Find a Cure for Alzheimer's

Not everyone who's blessed with a long life will remember it. Individuals who live into their mid-80s have a nearly 50 percent chance of developing Alzheimer's, and scientists still haven't discovered any groundbreaking treatments for the neurodegenerative disease [PDF]. To pave the way for a cure, Microsoft co-founder and philanthropist Bill Gates has announced that he's donating $100 million to dementia research, according to Newsweek.

On his blog, Gates explained that Alzheimer's disease places a financial burden on both families and healthcare systems alike. "This is something that governments all over the world need to be thinking about," he wrote, "including in low- and middle-income countries where life expectancies are catching up to the global average and the number of people with dementia is on the rise."

Gates's interest in Alzheimer's is both pragmatic and personal. "This is something I know a lot about, because men in my family have suffered from Alzheimer’s," he said. "I know how awful it is to watch people you love struggle as the disease robs them of their mental capacity, and there is nothing you can do about it. It feels a lot like you're experiencing a gradual death of the person that you knew."

Experts still haven't figured out quite what causes Alzheimer's, how it progresses, and why certain people are more prone to it than others. Gates believes that important breakthroughs will occur if scientists can understand the condition's etiology (or cause), create better drugs, develop techniques for early detection and diagnosis, and make it easier for patients to enroll in clinical trials, he said.

Gates plans to donate $50 million to the Dementia Discovery Fund, a venture capital fund that supports Alzheimer's research and treatment developments. The rest will go to research startups, Reuters reports.
