Amazons Black Friday sale has record-low prices on the Ember Smart Mug 2. The accessory heats your beverage to a set temperature (and keeps it there until youre done), ensuring your coffee, tea or hot chocolate is just right. In this sale, you can get the 10-oz. model, which usually retails for $130, for as little as $75.49. The larger 14-oz. Smart Mug 2 (typically $150) is on sale for as low as $91.49. The second-generation Ember mug is one of our favorite gifts for moms and teachers. The self-heating mug lets you set a preferred temperature in the iOS or Android app. It will then remember that the next time you fire it up, keeping your beverage at your ideal temp without any extra fuss. You can also add presets for different kinds of drinks. It can keep drinks anywhere from 120 to 145 degrees Fahrenheit, depending on your preference. The Smart Mug 2 has an auto-sleep feature that senses when its empty and stops heating. So, you shouldnt have to worry about coffee residue burning to a crisp in the bottom after youve finished. (Ew.) The mug is IPX7-rated, meaning its submersible in up to a meter of water. However, its a hand-wash-only product, so dont make the mistake of plopping it in the dishwasher by force of habit. The Ember mug lasts an estimated 80 minutes on a full charge. It also includes a charging coaster that can keep it heating all day. If you want to use it on the go, Ember sells an optional sliding lid. The Black Friday sale prices vary by color. For example, the white variant is the cheapest in both sizes, followed by black ($79.49 for 10 oz., $96 for 14 oz.). Meanwhile, the popular copper model costs $110 and $127.49, respectively.

Researchers from the University College London have done what celebrity chefs and Italian nonnas could only dream of: they've made the world's thinnest spaghetti. This culinary-sounding accomplishment, published in Nanoscale Advances, has yielded strands of starch nanofibers that are just 372 nanometers wide, which is invisible to the naked eye and is even smaller than some wavelengths of light. "The world's thinnest spaghetti" sounds silly, but starch can actually have important applications in medicine. For instance, nanofiber starches could help wounds heal when used in bandages, since they'd be able to keep out bacteria while allowing moisture through. Rather than going through the energy-intensive process of refining their own plant cell starch for nanofibering, these chemists decided store-bought was fine and made their strands directly from flour. Their version of the nanofibers were created with a process called electrospinning, where an electric charge pulls a flour and liquid mixture through extremely small metal holes into threads that are just nanometers wide. Extrusion through a die is literally the same way you'd make conventional spaghetti to accompany your bolognese or your meatballs, only at a much, much smaller scale. There's still a lot of study to be done before the product will be appearing in the doctor's office, but this is a step toward more sustainable starch nanofibers. And while I would pay good money to watch chefs try to explain invisible pasta on a reality show, electrospinning almost certainly won't become the new molecular gastronomy hotness. As co-author Professor Gareth Williams of the UCL School of Pharmacy put it: "I don't think it's useful as pasta, sadly, as it would overcook in less than a second, before you could take it out of the pan."This article originally appeared on Engadget at https://www.engadget.com/science/chemists-have-created-the-worlds-thinnest-spaghetti-201509365.html?src=rss

The 4K Chromecast with Google TV streaming stick is down to $40 on Amazon as part of a Black Friday sale. Thats a savings of 20 percent, or ten bucks for the math wizards out there. We called the 1080p version of this device a great little streaming dongle and that certainly holds true for the newer 4K model. It supports HDR and is compatible with just about any TV with an HDMI port. Once plugged in, it streams via Wi-Fi. The model also allows users to view live TV in 4K. This works with a bunch of different live TV providers, like YouTube TV, Pluto TV, Sling TV and Philo. It ships with a voice remote embedded with Google Assistant, allowing people to bark orders regarding what stuff they want to watch. As with most streaming sticks, users can cast stuff from their phones or tablets. Theres also the option to build a kid-friendly profile, complete with family-friendly content and robust parental controls. However, there is one caveat here. This model is likely on the way out. The company looks to be prioritizing the recently-released Google TV Streamer, which drops the dongle design in favor of a wedge. This one boasts more storage and a faster CPU than the aforementioned dongle. The company also shoehorned some AI in the new device because thats what everyone must do now. However, the Google TV Streamer costs $100. Id go for the $40 Chromecast myself. Check out all of the latest Black Friday and Cyber Monday deals here.This article originally appeared on Engadget at https://www.engadget.com/deals/black-friday-deals-include-the-4k-chromecast-with-google-tv-for-40-194854930.html?src=rss
