 Scientists have reimagined the meaning of a "light meal," creating microlasers that use natural products to emit illuminated beams through food. And they're completely edible. These mini lights, the first demonstration of laser emission from an entirely edible system, could be harnessed for everything from environmental sensors to food safety trackers and bio-barcodes.

You can save today on our top security camera pick for Alexa users. Amazon has the Blink Outdoor 4 for half price. A single camera (usually $100) only costs $50, which is only $10 more than its all-time low for Black Friday. And the half-off savings also apply to multi-camera bundles.
The Blink Outdoor 4's name is somewhat deceiving because it works just as well for indoor use. The weather-resistant camera records in up to 1080p and supports black-and-white infrared for nighttime recording. The wireless camera is powered by a pair of AA batteries.
If the impressive Blink Outdoor 4 has an asterisk, it's the company's

The Apple TV is one of the best streaming devices you can get right now to add Netflix, Disney , Max and other streaming apps to your boring old TV. It costs more than the competition, but it offers a more polished experience (the screensavers are worth the price of admission) as well as more privacy protections.
One perk of Apple TV you may not know about is its support for several native VPN apps. You can use a VPN to unlock shows, movies, and sporting events that are usually restricted to other territories. If you use a VPN to change your IP address to a different virtual location, you can fool streaming sites into changing what content they make available. Here's how to use a VPN on your Apple TV and why you might want to install one.
How to use a VPN on Apple TV
As of the September 2023 release of the tvOS 17 software update, the Apple TV platform supports third-party VPN apps. Setting them up is easy; just follow these steps (these may vary slightly between VPNs):
In the Apple TV App Store, search for the VPN you want to download or search for the keyword "VPN" to see your options.
Download and install your chosen VPN.
Sign up or log in.
Choose a server location in a different country.
Once the VPN is up and running, return to the home screen and run the streaming app of your choice. In some cases, it will give you access to a new set of programming options based on your new virtual location.

For people with two hands, one is usually dominant. On a molecular level, life takes this to the extreme. All of the DNA in earthly living things twists to the right, whereas the protein building blocks favor a kind of left-handed chemistry. But in recent years, scientists have worked toward a kind of mirror version of life. The technology to make mirror life likely won't exist for at least a decade. Still, a group of concerned scientists published a 299-page technical report calling for a stop to the science. New York Times science columnist Carl Zimmer explains how a mirror microbe could wreak havoc on life on Earth in the future.
Check out the full technical report and Carl's full article.

Hyundai Motor envisions an interactive and partially virtual future it calls "metamobility," in which a variety of robotic devices interact with humans to provide a wide range of mobility services, from automated personal transport to remote control of robots in factories.
Hyundai executives, led by Chief Executive Euisun Chung, elaborated on the vision during a press conference at the annual Consumer Electronics Show in Las Vegas on Tuesday.
Buzzwords aside, Hyundai plans to leverage its growing expertise in robotics and artificial intelligence to build a future mobility network that connects humans in the real world with objects and tasks in the virtual world.
