This Fitness Startup Lets You Pay for Gym Time by the Minute

In a perfect world, factors like time, money, and convenience would never stand in the way of your workouts. But as anyone who’s signed up for a gym membership and never got around to using it knows, that isn't always the case. A new startup aims to make fitness more accessible to people who are unwilling or unable to make a serious financial commitment up front. As Fast Company reports, POPiN lets users at several participating health clubs in New York City pay for gym time by the minute whenever they want.

The concept applies sharing economy principles to the fitness industry. Members with the app on their iPhone or Android phone can choose from four gyms currently partnered with the startup. Each center includes luxurious amenities that are normally exclusive to members paying roughly $200 a month. With POPiN, users can walk in, check in with the front desk, pay $.15 to $.26 for each minute they’re there, and check out before they leave. A 45-minute workout might end up costing them around $8.

The average gym membership goes for nearly $60 a month, and gyms depend on the fact that a significant chunk of their customers let memberships go to waste. POPiN claims it is designed for people who might be more comfortable hitting the treadmill every day one week and taking a break from the gym the next, as opposed to adhering to a strict schedule. With a variety of fitness centers in their system, POPiN also wants to give its users greater access to a diverse range of equipment than they would get with a single gym.

The app has been around for only a few months and is limited to New York City for now, but the long-term plan is to expand to more cities across the country within the year. If you’re still waiting for POPiN to arrive in your area, here are some more app-based ways to improve your exercise regimen today.

New Cancer-Fighting Nanobots Can Track Down Tumors and Cut Off Their Blood Supply

Scientists have developed a new way to cut off the blood flow to cancerous tumors, causing them to eventually shrivel up and die. As Business Insider reports, the new treatment uses a design inspired by origami to infiltrate crucial blood vessels while leaving the rest of the body unharmed.

A team of molecular chemists from Arizona State University and the Chinese Academy of Sciences describe their method in the journal Nature Biotechnology. First, they constructed robots that are 1000 times smaller than a human hair from strands of DNA. These tiny devices contain enzymes called thrombin that encourage blood clotting, and they're rolled up tightly enough to keep the substance contained.

Next, researchers injected the robots into the bloodstreams of mice and small pigs sick with different types of cancer. The DNA sought the tumor in the body while leaving healthy cells alone. The robot knew when it reached the tumor and responded by unfurling and releasing the thrombin into the blood vessel that fed it. A clot started to form, eventually blocking off the tumor's blood supply and causing the cancerous tissues to die.

The treatment has been tested on dozen of animals with breast, lung, skin, and ovarian cancers. In mice, the average life expectancy doubled, and in three of the skin cancer cases tumors regressed completely.

Researchers are optimistic about the therapy's effectiveness on cancers throughout the body. There's not much variation between the blood vessels that supply tumors, whether they're in an ovary in or a prostate. So if triggering a blood clot causes one type of tumor to waste away, the same method holds promise for other cancers.

But before the scientists think too far ahead, they'll need to test the treatments on human patients. Nanobots have been an appealing cancer-fighting option to researchers for years. If effective, the machines can target cancer at the microscopic level without causing harm to healthy cells. But if something goes wrong, the bots could end up attacking the wrong tissue and leave the patient worse off. Study co-author Hao Yan believes this latest method may be the one that gets it right. He said in a statement, "I think we are much closer to real, practical medical applications of the technology."

New Peanut Allergy Patch Could Be Coming to Pharmacies This Year

About 6 million people in the U.S. and Europe have severe peanut allergies, including more than 2 million children. Now, French biotechnology company DBV Technologies SA has secured an FDA review for its peanut allergy patch, Bloomberg reports.

If approved, the company aims to start selling the Viaskin patch to children afflicted with peanut allergies in the second half of 2018. The FDA's decision comes in spite of the patch's disappointing study results last year, which found the product to be less effective than DBV hoped (though it did receive high marks for safety). The FDA has also granted Viaskin breakthrough-therapy and fast-track designations, which means a faster review process.

DBV's potentially life-saving product is a small disc that is placed on the arm or between the shoulder blades. It works like a vaccine, exposing the wearer's immune system to micro-doses of peanut protein to increase tolerance. It's intended to reduce the chances of having a severe allergic reaction to accidental exposure.

The patch might have competition: Aimmune Therapeutics Inc., which specializes in food allergy treatments, and the drug company Regeneron Pharmaceuticals Inc. are working together to develop a cure for peanut allergies.
