The Best Mattress From Every Top Brand, According To Online Reviews

A lot has changed since Casper shook up the sleep industry in 2014 with its signature bed-in-a-box. These days, buying one of the best mattresses online seems to be the norm rather than the exception. There are now hundreds of mattress start-ups all vying for a piece of the market, and all promising to grant you something that for many still remains elusive: a good night’s sleep. 

Thankfully, all the competition has spawned some serious innovation. That’s good news for anyone who likes a lot of choice when it comes to mattress materials and level of support. You can now select from a foam mattress, hybrid coil mattress, or opt for a totally organic foam mattress. But all the options don’t necessarily make it any easier to select the best mattress for your needs, whether you’re a side-sleeper, stomach sleeper or tosser-and-turner. 

To help narrow down your picks, we’ve

CIO says tech bubble not expected to pop anytime soon

Tech stocks are unequivocally in “bubble” territory, a chief investment officer told CNBC on Monday, but that’s not to say the recent “tech wreck” is going to continue in the short term.

U.S. stocks closed lower for the second consecutive session on Friday, bringing an end to a volatile trading week ahead of the long Labor Day weekend.

The S&P 500 tech sector fell more than 4% for the week, intensifying speculation that the stock market shakeout was likely not over yet. The space had largely been responsible for the broader market’s strong comeback off its coronavirus lows.

“I think we are certainly in bubble territory,” Jonathan Bell, chief investment officer at Stanhope Capital, told CNBC’s “Street Signs Europe” on Monday.

Bell suggested there had been “so many good reasons” for investors to own the likes of Google-parent company Alphabet, Amazon, Apple, Microsoft and Facebook, pointing to their combined outperformance

The most commonly used method for the taxonomic identification of tree trunks is wood anatomy. The number of experts in this area is decreasing, and education to become an wood anatomists takes many years. With the help of technology computer scientists of the Leiden Institute of Advanced Computer Science (LIACS) in collaboration with wood anatomists from Naturalis Biodiversity Center and internationally renowned specialists hope to develop a computer-aided tool for wood identification.

Horizon Zero Dawn PC Patch Improves Performance Up To 10%

Horizon Zero Dawn launched on PC little over a month ago with numerous performance and technical issues, which developer Guerrilla Games has been chipping away at. While the last patch fixed a bug that kept you as a baby Aloy forever, the latest update is all about performance increases.

Patch 1.04 address multiple reported issues across the game but is headlined by a CPU optimization that Guerrilla says could increase performance up to 10% on some systems. The change also helps the performance during cutscenes and dialogue transitions, which could often see the frame rate dip incredibly low in pivotal story moments.

Elsewhere the patch touches up banding issues that players using HDR were reporting, as well as a fix for mouse sensitivity that would go out-of-sync with the setting when the frame rate was not stable. Fixes for issues around aiming bugs and geometry pop-in have also been included,

Instagram Reels Is “Basically The Same”

Watch out, TikTok.

Almost nine in ten TikTok users who have used Instagram Reels say that Facebook’s TikTok competitor is basically the same as TikTok. And 61% said they’ll be spending more time in Instagram as a result.

“This strong number for Instagram is driven by the fact that TikTok users who have used Instagram Reels do not think that TikTok is inherently special,” says Tommy Walters, research and insights managers at social media content company Whistle.

That is my sentiment exactly.

TikTok, of course, is being forced to sell to an American company by the Trump administration, although the company is contesting that order in court. That controversy doesn’t have appeared to hurt TikTok: it is still the third

Bio-inspired zinc battery could change how robots burn energy

More and more robo-tech is evolving in an ironic turn that goes against many of the cold metal worlds in science fiction, where flesh has been taken over by machine. Maybe the most unexpected biomimetic — literally mimicking biological creatures — technology is a robot battery that stores energy like fat.

Sorry, Baymax, but robots will actually lose weight with a new “fat battery” (tech throughout history has often shed bulk with each upgrade). University of Michigan professor Nicholas Kotov — a professor of chemical engineering, materials science and engineering, and macromolecular science and engineering — has developed a zinc battery that could really level up the function of everything from nurse and server droids to delivery drones to micro- and nanobots. Smaller but much more energy-dense than the typical lithium ion battery, it can power a robot just as biological fat reserves can keep us going.

“Such multifunctional batteries

Charlette N’Guessan wins Royal Academy of Engineering’s Africa Prize for innovation

Charlette N’Guessan is the first woman to win the award, which could revolutionize cyber security and help curb identity fraud on the continent.

N’Guessan and her team won the £25,000 award (about $33,000) for BACE API, a digital verification system that uses Artificial Intelligence and facial recognition to verify the identities of Africans remotely and in real time.

BACE API works by matching the live photo of a user to the image on their documents such as passports or ID card, N’Guessan said.

For websites and online applications that have BACE API integrated in them, users will be verified via their webcam to establish their identity.

“For the person trying to submit their application, we ask them to switch on their camera to make sure the person behind the camera is real, and not a robot.

“We are able to capture the face of the person live and match their

China is in for ‘a tough time’ as U.S. targets tech sector, expert says

SINGAPORE — China is in for “a tough time” in the short term as the U.S. tries to deny it access to crucial tech components, a business consultant told CNBC on Monday.

Tensions between the two countries in the technology space heated up over the weekend with the U.S. considering blacklisting China’s largest chipmaker, Semiconductor Manufacturing International Corporation or SMIC.

The measure would restrict SMIC from obtaining specific goods made in the U.S. Even though China has been developing its own semiconductor manufacturing capabilities, companies such as SMIC still relies on American equipment in its production line.

Richard Martin, managing director of IMA Asia, told CNBC’s “Squawk Box Asia” that China may have to “look elsewhere” for supply of semiconductors if SMIC’s ability to produce them is crippled by the U.S. move.

“The problem with looking elsewhere is if you go to Europe or if you go to Japan, the

TSA continues piloting “self-service” checkpoint technology

WASHINGTON – The Transportation Security Administration (TSA) is piloting a new touchless “self-service” technology that matches a traveler’s live photo with the photo on their ID. The initiative automatically authenticates a traveler’s ID, matches the live photo with the image on their ID, and confirms their flight information in near real time. 

“In light of COVID-19, advanced health and safety precautions have become a top priority and part of the new normal for TSA,” said TSA Administrator David Pekoske. “As a result, we are exploring rapid testing and deployment of this touchless, self-service technology. At the conclusion of the pilot, we expect to be able to determine how positioning the new technology will allow passengers to use it themselves thereby providing a safer checkpoint experience, while adding significant security benefits.” 

The current pilot at Ronald Reagan Washington National Airport (DCA) follows a previous 30-day test of the credential authentication technology
