If youve been eyeing the reMarkable 2 for a while, now is a great time to buy one. While the E Ink tablet itself isnt on sale, reMarkable has discounted the two bundles it offers alongside the 2. Until the end of December 2, you can save $89 off the Type Folio and Book Folio bundles. Both include reMarkables Marker Plus stylus, which comes with an eraser feature not found on the regular Marker stylus. Its also black instead of gray and four grams heavier. As for the two folios, the type one is the one to buy if you need a keyboard. The reMarkable 2 is easily the best E Ink tablet you can buy right now. Its the top pick in our E Ink tablet guide, and for good reason. It boasts a tremendous reading and writing experience, with a responsive, low-latency display that offers the closest pen-and-paper experience among the tablets Engadget tested. The reMarkable 2 makes accessing your favorite books and files easy, too. It includes support for both PDFs and ePUBs, and you can link your Google Drive, Microsoft OneDrive and Dropbox to make transferring those files a cinch. Each new reMarkable 2 tablet also comes with a complimentary one-year subscription to Remarkable Connect, which is great for transferring any notes you write to your other devices. One of the few downsides of the ReMarkable 2 is how expensive it is to buy. Although reMarkable hasnt directly discounted the tablet, a folio cover and Marker Plus stylus are accessories most people will probably want to buy anyway, so this Black Friday promotion still makes the device more accessible. Check out all of the latest Black Friday and Cyber Monday deals here.This article originally appeared on Engadget at https://www.engadget.com/mobile/tablets/black-friday-deals-include-remarkable-2-bundles-for-89-off-210003470.html?src=rss

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
