Forget the cold brew. Forget the nitro brew. Forget the soy milk, light ice, extra shot of espresso, toasted gingerbread latte. Don't you miss just a good old-fashioned cup of coffee?
Although you were usually half asleep when trying to brew a pot, wasn't there something exciting about fumbling around looking for the filters? Or am I just getting too excited at the thought of coffee? Either way, the paper filters may be obsolete but that motivating feeling that only comes from hearing a coffee maker do its thing lives on.
Whether it's using K-cups or your own grinds, some highly loved (and rated) coffee makers are on sale on Amazon. If you don't have much space in your kitchen, the reliable and slim Keurig K-Mini Coffee Maker may be the perfect fit for you — and it's under $70. Or maybe you want your choice between a single serve or whole pot brew, which you can get with the Hamilton Beach 2-Way Brewer Coffee Maker that's on sale for under $60. Read more...
TL;DR: The ASUS M409 14-inch laptop is on sale for £479.99 on Amazon, saving you 20% on list price.
The whole idea of a laptop is that it's supposed to be portable. You have a desktop for your home office, and a laptop for getting stuff done on the go. That's just the way it is.
This doesn't mean that all laptops are equally portable though, and some devices definitely prioritise power and performance over everything else. The key is finding balance, as you'll want a laptop that delivers on everything.
The ASUS M409 14-inch laptop offers the best of both worlds, with an AMD Ryzen 7 Processor, 512 GB SSD, and 8 GB of RAM packed into a lightweight frame. It's a great option for work or play thanks to the NanoEdge display, boasting wide viewing angles and a matte anti-glare coating for an engaging experience. Read more...
It's great to get out of the country. But what happens when you get to Colombia or France or Belarus, finally sort out your phone and find some free WiFi, pull up the Uber app, order a ride on your phone just like you do back home, and then your driver messages you something ... but you have no idea what.
Starting Thursday, Uber is adding a translation feature to its ride-hailing messaging platform. It's supposed to help when you're traveling abroad and need to communicate with a driver who speaks in a different preferred language. Using the Google Translate API, you and your driver can see messages in each of your preferred languages. More than 100 languages will be supported on the Uber app. Read more...
A federal appeals court has upheld the dismissal of a lawsuit against Google by PragerU. By coming to that decision, the judges backed the previous court's ruling that internet platforms aren't subject to the free speech requirements of the First Amendment. If you'll recall, Dennis Prager, a conservative radio host and YouTuber who runs the channel PragerU, sued the tech giant in 2017. He accused Google of being biased against conservatives by putting age restriction on his content and blocking third parties from running ads on his videos, which feature conservative viewpoints on topics like abortion, gun rights and Islam.

For most of human history, diamonds were extraordinarily rare, and there was no way to artificially produce them. Scientists have learned to make diamonds in laboratories, but the process had numerous drawbacks. Researchers from Stanford University and SLAC National Accelerator Laboratory have been working on a new technique. According to a new study, the team has succeeded in producing pure diamonds using a trace material found in fossil fuel deposits.
Diamonds have always been prized for their appearance, but their unique combination of optical clarity and hardness means they’re also useful today in medicine, biological sensing, manufacturing, and even quantum computing. Natural diamonds form deep in the Earth’s crust, where temperatures and pressure squeeze carbon into a diamond lattice. Recreating that in the lab has always required a great deal of energy, time, or the addition of a metal catalyst that leaves impurities in the final product.
Scientists have long studied a class of molecules called diamondoids to better understand the properties of diamonds. Diamondoids occur naturally in fossil fuel deposits like crude oil and natural gas and consist of carbon and hydrogen. When isolated, diamondoids look like a fine, white powder, but on the molecular level, they contain the smallest “cage” unit structure of the diamond crystal lattice. The researchers collected three different forms of diamondoid to test.
Diamondoid structures. Triamantane is a three-cage molecule.
Fittingly, you need diamonds to make diamonds from diamondoids. The team loaded the samples into a diamond anvil cell, which can subject small objects to incredible pressure. Next, they heated the compressed samples with a laser. Under these conditions, the carbon bonds reorient into the standard diamond lattice, and the hydrogen atoms fall away. A three-cage diamondoid called triamantane turned out to be the best at forming diamonds. It took 20 gigapascals of pressure and a temperature of 1,160 degrees Fahrenheit (626 degrees Celsius) to transform triamantane powder into a pure diamond.
This process is faster and cheaper than other methods of producing diamonds, but it has one major drawback: scale. A diamond anvil cell can only compress very small samples, so you can only make microscopic diamonds from diamondoids — at least for now. This process could help scientists better understand what it takes to make a diamond and improve the way they’re produced in the lab.
