Alphabet’s revenues are still growing, but just barely

It’s no secret that the huge tech companies are still making money hand over fist, but there’s also a noticeable slowdown going on. Google’s parent company Alphabet is not immune — the company just reported its earnings results for Q4 of 2022, and just barely grew revenue year over year. The $76 billion the company pulled in during the quarter is up only one percent from Q4 of 2021. 

Google’s ad business is the backbone of the company, and revenue slipped there by about 3.5 percent compared to a year ago. But eight percent growth in the “other” category (which includes products like Google and Nest hardware and revenue from the Play Store) and 32 percent yearly growth in in Google Cloud made up for those ad losses. Overall profits, meanwhile, dropped significantly: Quarterly net income of $13.6 billion is down 34 percent year-over-year.

Of course, the backdrop for all this is that Google announced a few weeks ago that it is laying off about 12,000 employees; that makes up about six percent of the company’s overall workforce. At the time those layoffs were announced, we didn’t yet know what Google’s financials for last quarter looked like, but now we can see that things are slowing down. 

That’s all relatively speaking, though. Net income of $60 billion for 2022 as a whole was down significantly compared to the $76 billion in profit Alphabet made in 2021 — but it’s still far ahead of the $40 billion the company pulled in for 2020. It looks like the big numbers Alphabet posted in 2021 weren’t exactly sustainable, and obviously we don’t yet know what 2023 will bring. But we’ll be tuning into the company’s call with investors, which starts at 4:30PM ET, to see what additional details CEO Sundar Pichai can share about the state of Alphabet in the year to come.

Columbia researchers bioprint seamless 3D skin grafts for burn patients

The science of grafting skin has come a long way from the days of scraping it off one part of a patient’s body and slapping it back on somewhere else to cover a nasty burn or injury. These days grafts are commonly bioprinted like living inkjets using the patient’s cultured cells to seed the growing process, down to the vascularization. The primary shortcoming of these printed grafts is that they can only be produced in flat sheets with open edges. This method “disregard[s] the fully enclosed geometry of human skin,” argue a team of researchers from Columbia University. Instead, they’ve devised a novel means of producing skin in virtually any complex 3D shape they need — from ears and elbows to entire hands printed like a pair of Buffalo Bill’s mittens.

The team published their findings, “Engineering edgeless human skin with enhanced biomechanical properties,” in the January issue of Scientific Advances. They explained how they engineered, “the skin as a fully enclosed 3D tissue that can be shaped after a body part and seamlessly transplanted as a biological clothing.”

“Three-dimensional skin constructs that can be transplanted as ‘biological clothing’ would have many advantages,” Dr. Hasan Erbil Abaci, lead researcher and assistant professor of dermatology at Columbia University, said in a recent press release. “They would dramatically minimize the need for suturing, reduce the length of surgeries, and improve aesthetic outcomes.” 

What’s more, these uniform grafts have shown superior performance, both mechanically and functionally, than their patchwork alternatives. The Columbia team has dubbed the grafts “wearable edgeless skin constructs” (WESCs). Ok, but can you eat them?

The process of making these skin prosthetics isn’t that far off from the existing techniques which result in flat slabs of skin. The transplant site is first scanned with a 3D laser to create a digital facsimile of the structure. That data is worked through a CAD program to generate a hollow wireframe of the appendige and then printed. This serves as the scaffolding on which the patient’s cultured cells will grow. It’s coated with skin fibroblasts and collagen then covered by an outer layer of keratinocytes (which make up the epidermis) and growth medium to feed the cells as they mature. As with making flat sheets, the entire process requires around three weeks for the cells to fully set up and be ready for transplant.

Initial lab tests with mouse models were encouraging. “It was like putting a pair of shorts on the mice,” Abaci said. “The entire surgery took about 10 minutes.” Don’t get too excited, mouse skin is not people skin. It heals differently enough that additional animal studies will be required before we start trying it on humans. Such tests are likely still years away.

Antartica’s only EV had to be redesigned because of climate change

Most electric vehicles get upgrades to boost performance or range, but Antarctica’s one and only EV has received a tune-up due to the realities of climate change. Venturi has revealed that it upgraded its Venturi Antarctica electric explorer early last year due to warmer conditions on the continent. The original machine was designed to operate in winter temperatures of -58F, but the southern polar region is now comparatively balmy at 14F — and that affected both crews and performance.

The company has added a ventilation system and air intakes to the front of the Antarctica to prevent overheating in the cockpit, while additional intakes keep the power electronics from cooking. Redesigned wheel sprockets were also necessary to maximize the tracked EV’s capabilities. The warmer snow was sticking to the sprockets, creating vibrations as it compacted and hardened. Future upgrades will help restore range lost to changing snow consistency. The Antarctica is built to cover 31 miles, but scientists have been limiting that to 25 miles.

Ars Technicanotes Venturi’s EV has been in use at Belgium’s Princess Elisabeth Antarctica Station since December 2021. It has two modest 80HP motors and just a 52.6kWh battery (plus an optional second pack), but raw power isn’t the point. The design lets station residents perform research without contributing to emissions or polluting a relatively pristine region.

You might not see Venturi make similar climate-related upgrades for a while. However, the refresh shows how global warming can affect transportation in subtle ways. Venturi and other manufacturers may have to design their next explorers on the assumption that Antarctica won’t be as chilly as before.

Arlo video doorbells and security cameras are up to half off

Folks on the lookout for a new video doorbell or home security camera might be interested in checking out the latest sale on Arlo gear. You can snap up the devices for up to half off at the minute, with the Essential Wire-Free Video Doorbell seeing the biggest drop from $200 to $100.

The doorbell, which you can plug in if you wish, offers a 180-degree wide field view and HD video with HDR.

‘Star Wars: Visions’ Volume 2 debuts May 4th with an Aardman short

Star Wars: Visions is returning for a second ‘season,’ this time with a more international scope — including a studio you might not have expected. Disney has announced that Star Wars: Visions Volume 2 will premiere May 4th (aka Star Wars Day) with shorts from nine countries, including one from UK stop-motion legend Aardman. Details of the project (“I Am Your Mother”) aren’t available, but it’s directed by Wallace & Gromit veteran Magdalena Osinska.

Other titles come from 88 Pictures (India), Cartoon Saloon (Ireland), D’art Shtajio (Japan), El Guiri (Spain), Punkrobot (Chile), Studio La Cachette (France), Studio Mir (South Korea) and Triggerfish (South Africa). Some of the creators have illustrious credentials. El Guiri’s Rodrigo Blaas is a Pixar alumnus, for example, while Triggerfish has worked on BBC titles like The Highway Rat and Stick Man.

The first Visions focused on Japanese anime studios’ approach to the Star Wars universe, including well-known names like Production I.G (Ghost in the Shell: Stand Alone Complex) and Trigger (Kill la Kill). Creators were given more creative freedom than those producing canonical movies and TV shows — they were free to not only pursue different art styles and themes, but to break continuity with the official storyline. That’s likely to continue with Volume 2, as series executive producer James Waugh says the anthology is about “celebratory expressions” of Star Wars that open “bold new ways” of telling stories in the space fantasy setting.

The Visions release date bolsters an increasingly packed Star Wars release schedule at Disney+. It starts with The Mandalorian season three on March 1st, but will also include Young Jedi Adventures (spring), Ahsoka and Skeleton Crew. You’ll have plenty to watch, then, even if the animated shorts aren’t to your liking.
