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.

Taylor Swift (Possibly) Used Facial Recognition to Catch Stalkers at Concert

Look what you made Taylor Swift do: The singer-songwriter reportedly employed facial recognition software to scan for stalkers at her Rose Bowl concert in May.

As reported by Rolling Stone, the fan-favorite kiosk showing clips of Swift in rehearsal was actually a front for high-tech security.

Inside, a hidden camera snapped photos of people as they peered in to watch run-throughs of the May 18 stadium event.

Images, sent to a “command post” in Nashville, were then cross-referenced with a database of hundreds of the pop star’s known stalkers, according to Mike Downing, chief security officer at Oak View Group, an advisory board for concert venues.

“Everybody who went by would stop and stare at it, and the software would start working,” Downing, who personally attended the concert, told Rolling Stone.

Neither Oak View Group nor Swift’s reps immediately responded to a request for comment.

It is unclear who owns the kiosk in question, and whether the collected footage was kept on file. Or, for that matter, whether any real stalkers were identified by surveillance officers some 2,000 miles away.

Before you call a lawyer or draft a petition, keep in mind that concert venues are typically private locations. Which, according to Quartz, means that owners can subject attendees to “any kind of surveillance they want”—including facial recognition.

Despite its privacy concerns, the technology is on the rise, cropping up in China, where police are experimenting with AR glasses and authorities are cracking down on jaywalkers, and the US.

Early this year, Customs and Border Protection began rolling out cameras at the Mexico-Texas border, and the Secret Service are planning to test similar tech at the White House.

These sorts of trials have, understandably, conjured an Orwellian “Big Brother” impression across the country, where folks are concerned that ever-evolving facial recognition technology may not always be accurate.

Virgin Galactic Is Ready to Go to Space

Virgin Galactic hopes to reach space for the first time today (weather permitting).

Richard Branson’s spaceflight company this week revealed the window for its next powered test flight of VSS Unity opens on Dec. 13.

“We are currently planning to fly at the opening of that window on Thursday, pending acceptable weather and technical readiness,” a blog post said.

No further announcements have been made.

During this fourth phase of testing, the firm hopes to push VSS Unity higher and faster than ever before, burning the rocket motor for longer (though not to its full duration).

“Although this could happen as soon as Thursday morning, the nature of flight test means that it may take us a little longer to get to that milestone,” the company admitted.

As of October, Virgin Galactic was “more than tantalizingly close” to leaving Earth’s atmosphere, according to Richard Branson.

“We should be in space within weeks, not months,” the Virgin Group founder and CEO told CNBC.

“And then we will be in space with myself in months and not years,” he continued. “And then we’ll be in space with people not too long after that.”

Since its founding in 2004, the spaceflight company has been on a rollercoaster to the cosmos: The White Knight Two carrier plane and suborbital SpaceShipTwo flew together in 2010.

But a series of delays has grounded the firm, which suffered a disaster four years ago, when the VSS Enterprise broke apart in midair, killing co-pilot Michael Alsbury and seriously injuring pilot Peter Siebold.

Replacement ship VSS Unity completed its first successful glide test in December 2016, and another six by January of this year. It performed powered test flights in April and May.

“Incremental flight test programs are by definition open-ended and, to a great extent, each test depends on the data from the test that precedes it,” the blog said. “There is no guarantee that everything will work perfectly first time and, like all programs seeking to take bold steps, we will inevitably have times when things don’t go as planned.

“Our team’s biggest priority is to use meticulous planning and preparation to ensure that stages are dealt with safety, and that every outcome informs and improves future performance,” Virgin Galactic continued.

Keep an eye on the skies, as Branson & Co. gear up to finally take their first trip to space.

Robot Successfully Delivers Coral Babies to Great Barrier Reef

Call the drone midwife: A robot successfully delivered coral larvae directly onto the Great Barrier Reef in Australia.

In a world first, an undersea android dispersed microscopic baby corals as part of a project to to help repopulate parts of the 1,429-mile ecosystem.

The initiative builds on Southern Cross University professor Peter Harrison’s larval reseeding technique, piloted on the southern Great Barrier Reef in 2016 and 2017.

“This year represents a big step up for our larval restoration research,” Harrison said in a statement.

“[It is] the first time we’ve been able to capture coral spawn on a bigger scale using large floating spawn catchers, then rearing them into tiny coral larvae in our specially constructed larval pools and settling them on damaged reef areas,” he explained.

Birthing partner Matthew Dunbabin, a professor at Queensland University of Technology, re-engineered QUT’s reef protector RangerBot into LarvalBot—specifically for Harrison’s project.

With a capacity to carry around 100,000 coral larvae per mission (and plans to scale up to millions), the robot gently releases the tots onto damaged reef areas, allowing them to settle and, eventually, develop into coral polyps.

“During this year’s trial, the robot was tethered so it could be monitored precisely,” Dunbabin said. “But future missions will see it operate alone and on a much larger scale.”

It’s like spreading fertilizer on your lawn,” he added.

Following this year’s initial trial, the pair plan to fully implement their proposal in 2019, using their specialized robot elsewhere in Australia, and around the world.

“With further research and refinement, this technique has enormous potential to operate across large areas of reef and multiple sites in a way that hasn’t previously been possible,” Harrison said. “We’ll be closely monitoring the progress of settled baby corals over coming months and working to refine both the technology and the technique to scale up further in 2019.”
