How much sun is too much? A group of Northwestern scientists aim to let you know with the world’s smallest wearable device, which can help prevent skin cancer.

Dubbed, “My Skin Track UV,” the device made its debut on Apple and La Roche-Posay’s websites last month, but the team released a paper in Science Translational Medicine on Wednesday that gives more details on its design and testing process. The group claims it’s the tiniest wearable device on the market and thankfully, it’s now available for customers to buy.

According to a Northwestern University press release, the device measures light exposure across various wavelengths from ultra violet (UV), to visible, and in some cases, infrared solar areas. The aim of the device is to alert customers about their UVA exposure and allow them to protect their skin from wrinkles, spots, and burns.

To put this device to the test, researchers solar-powered the device and attached them to human study participants. During testing, it recorded different types of light exposure when the participants were outside. It tracked therapeutic UV light in clinical phototherapy for skin conditions, including atopic dermatitis and psoriasis, blue light therapy for those suffering from jaundice, and white light exposure for mental health ailments, including seasonal affective disorder.

Due to its versatile monitoring activity, the device can foster precision phototherapy for the health conditions above, monitor UVA and UVB exposure for melanoma, and warn users when they’re spending too much time in the sun.

While this tiny device might seem great in the lab, it’s easy to use, according to John Rogers, the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering at Northwestern University.

“From the standpoint of the user, it couldn’t be easier to use – it’s always on yet never needs to be recharged,” Rogers said in the press release. “It weighs as much as a raindrop, has a diameter smaller than that of an M&M and the thickness of a credit card. You can mount it on your hat or glue it to your sunglasses or watch.”

Here’s how it works: First, the device captures and stores a minute electrical current from sunlight. A communication chip embedded in the device’s sensor interprets the voltage and passes the result digitally to the user’s smartphone. The device then communicates with their smartphone to gather global UV index information and they can see how much time they’ve spent in the sun or shade. If they’ve maxed out their sun exposure, their smartphone will send them an alert.

Before you embark on your Winter tropical escape, you might want to consider buying the “My Skin Track UV,” which retails for $59.95 at Apple.com.

Google Fit Now Tracks Workouts on iOS

Google Fit finally landed on iOS this week, four and a half years after the health app launched for Android.

Relying on the sensors in a connected fitness tracker or mobile device, Google Fit records and measures physical activities against the user’s fitness goals.

Released to the public in October 2014, the Android-based program got a makeover last year, with added objectives based on recommendations from the American Heart Association and World Health Organization.

The updates also aimed to help Fit provide better metrics for pursuits other than walking, and encourage folks to engage in exercises that raise heart rate without going to the gym.

“When we launched the new Google Fit last year, we translated the science behind physical activity into two simple and smart activity goals: Move Minutes and Heart Points,” product manager Defne Gurel explained in a blog post.

Track your Heart Points and Move Minutes earned (via Google)

The more you move, the more Move Minutes you earn. The more intensely you move, the more Heart Points you earn.

My Tuesday workout—15 minutes on the elliptical, 30 minutes of strength training—for instance, earned me 69 Move Minutes and 91 Heart Points. (Versus only three Move Minutes and zero Heart Points so far today. Thanks, head cold!)

“Whether you go biking or pick up your pace while walking to your next meeting … you can check your journal to track progress on these two activity goals and see how small changes can make a big impact to your health,” Gurel said.

Manually enter activities—everything from aerobics to Zumba—as well as calories burned, steps taken, and distance traveled; or connect Apple Health-compatible apps like Sleep Cycle, Nike Run Club, and Headspace to sync with Google Fit.

Smartwatch wearers, of course, have a direct link to the service, which automatically documents workout sessions via your Apple Watch or Wear OS.

“Tracking your progress throughout the day should be simple and easy. Regardless of which apps or devices you use to monitor fitness, sleep, and general wellbeing, Google Fit has you covered.”

FAA Greenlights Google Wing Drone Deliveries in US

Two weeks after Project Wing earned approval to make drone deliveries in Canberra, Australia, the Google offshoot got the greenlight to launch a similar service in the US.

On Tuesday, Wing became the first drone delivery company to receive air carrier certification from the Federal Aviation Administration.

“For communities across the country, this presents new opportunities,” the firm wrote in a blog announcement. “Goods like medicine or food can now be delivered faster by drone, giving families, shift workers, and other busy consumers more time to do the things that matter.”

Wing drones have already flown more than 70,000 test flights and completed more than 3,000 deliveries to doorsteps, driveways, and backyards for customers Down Under.

Service is expected to take off soon, starting with 100 eligible homes in the Canberra suburbs of Crace, Palmerston, and Franklin, before expanding into Harrison and Gungahlin.

A U.S. delivery trial, meanwhile, could start as early as “later this year” in Montgomery County, Va.

“For the next several months, we’ll be reaching out to businesses and community members in the Blacksburg and Christiansburg areas to demonstrate out technology, answer questions, and solicit feedback,” Wing said.

No further details—including how many drones or consumers will be involved—have been revealed.

“This is an important step forward for the safe testing and integration of drones into our economy,” U.S. Secretary of Transportation Elaine Chao said in a statement. “Safety continues to be our No. 1 priority as this technology continues to develop and realize its full potential.”

While the drones can fly autonomously, Wing will have certified pilots on the ground, ready to take control if necessary, according to CNN.

“Air delivery … provides greater autonomy to those who need assistance with mobility,” the company blog boasted. “Also, our all-electric drones will reduce traffic on our roads and pollution and carbon emissions in our skies.”

Amazon In-Garage Delivery Service Available for Prime Members

I trust Amazon delivery drivers as far as I can throw them. (Which, despite my thrice-weekly strength training routine at the gym, isn’t very far.)

So I have a hard time wrapping my head around the conglomerate’s Key dispatch program, which uses a suite of smart tech to grant temporary access to customers’ homes.

Now available in 50 U.S. cities, the bizarre program is expanding to include in-garage drop offs: Eligible Prime members can choose to have packages delivered “securely and conveniently” in their carport.

“We know it is important to keep innovating to make delivery as convenient as possible for customers, which is why we’re excited to now have Key for Garage available,” Rohit Shrivastava, the program’s general manager, said in a statement. “With this new option, members can truly unlock the convenience of the Amazon experience.”

For a fee, of course.

If you don’t already have a myQ-connected garage door opener, you’ll have to shell out $49.99 (regularly $79.99) for the myQ Smart Garage Hub—which lets you add connectivity to your existing garage door opener. Or just buy a myQ-connected Chamberlain or LiftMaster Wi-Fi garage door opener.

Simply select “in-garage delivery” at checkout to have packages delivered in your garage (via Amazon)

For the full experience, add an Amazon Cloud Cam (Key Edition) indoor security camera ($119.99) to watch your delivery happening live, or view a video clip of it later.

“With Key by Amazon, homeowners no longer have to reorganize their life to receive packages,” Chamberlain Group president and COO Jeff Meredith said.

Via the accompanying mobile app, customers receive updates leading up to an expected delivery window, as well as confirmation the driver is at the correct address with the correct parcel before access is granted.

“Key plus myQ smart garage access gives homeowners control over the package delivery process while offering a safe and convenient destination for unattended package delivery,” Meredith added.

Honestly, I’d rather take my chances with porch pirates than let a stranger into my front door or storage space.

Key by Amazon now serves 50 cities and their surrounding areas, including 13 new locations: Charlotte, N.C.; Columbus, Ohio; Fresno and Stockton, Calif.; Grand Rapids, Mich.; Hartford, Conn.; Las Vegas, Nev.; Norfolk and Virginia Beach, Va.; Oklahoma City, Okla.; Omaha, Neb.; Rochester, N.Y.; and Wilmington, Del.

Check your zip code online to get started with Key by Amazon delivery.
