Before there was pressure-treated wood, before modern paints, there was pine tar. Everything from tool handles to wagons to ships were made of wood preserved with pine tar, once upon a time, and [woodbrew] wants to show you how to make it, how to use it, and why you might put it on your skin.
It starts with, you guessed it, pine! In the first part of the video, [woodbrew] creates a skin salve with pine resin and food-safe oil. The pine resin–which is the sticky goop that dries around wounds on evergreen trees–is highly antiseptic and has been used in wound salves since the stone age. The process is easy: melt it in a double boiler, then mix with equal parts oil. [woodbrew] also adds a touch of beeswax to firm it up, an a little eucalyptus extract for extra germ-killing power, and a nice smell to boot.
That’ll preserve your hands, but what about preserving wood? That starts at about 9 minutes in, and for that you’re going to need a lot more resin, so picking it off wounded trees like he does at the start of the video won’t work. [woodbrew] suggests starting with dead-or-dying pines, and harvesting the crooks of their branches for “fatwood” — wood with the highest resin content. He also suggests the center of stumps, again of trees that died or were severely injured before being cut down. Then it’s a matter of cooking those fine organic molecules out. This is where we burn the wood to save the wood. Well, to save other wood. Wood we didn’t burn, obviously.
The distillation process [woodbrew] uses it fairly traditional, and consists of a couple of buckets. One bucket is buried and collects the pine tar; the other, with holes in the bottom to allow the tar to drip out, is filled with fatwood and covered tightly before being surrounded by firewood which is set alight. You could use an alternate source of heat here, but if you just cut down a pine tree for its fatwood, well, you’d have the rest of the tree to work with. Inside the fatwood bucket, the heat of the fire cooks off the volatile compounds that make pine tar, while the lack of oxygen from being closed up keeps it from burning. Burying the collection bucket keeps it from getting so hot the volatiles all boil off.

If this sounds like the process for making charcoal or woodgas, that’s because it is! He’s letting the gas fraction flare off here, but you could probably capture it– though a true gasifier brakes the tar down into gaseous compounds as well. The charcoal of course stays in the bucket as a bonus.
To make it usable as a wood finish, [woodbrew] mixes his homemade pine tar 50:50 with linseed oil, thining it to a spreadable consistency that helps it penetrate deep into the wood. By filling the voids in the wood, this mixture will help keep moisture out, and the antiseptic properties of the organic soup that is pine tar will help keep fungi at bay for potentially decades to come.
HarperCollins is tapping into AI to bring some of its book franchises to life. Specifically, the publisher is teaming up with Toonstar, an AI animation studio, to turn them into digital shows. The first project will be an adaptation of Lisa Greenwald’s “Friendship List” series, which will also be joined by a graphic novel.
You’d be forgiven for being unaware of Toonstar, a studio that received some buzzy early on for simplifying typically complex animation pipelines with AI, but has mostly remained under the radar. Its biggest claim to fame is producing StEvEn and Parker YouTube series, which has amassed 3.38 million subscribers and sometimes has episodes reaching around a million views. It’s not something I’ve heard animation fans speaking about, though. And honestly, it was tough to sit through a few minutes of its sub-South Park animation.
“By leaning into the [AI] technology, we can make full episodes 80 percent faster and 90 percent cheaper than industry norms,” Toonstar co-founder John Attanasio, told The New York Times last year. In that same interview, the company revealed that it uses AI across its production, including having it dub dialog for international audiences, as well as working on storylines.
Toonstar initially pitched itself as an animation studio leaning into Web3 and NFTs, but those technologies seem virtually absent from the company’s presence today. Space Junk, one of its early series, was “put on hold for a variety of reasons,” a representative told Engadget. “It’s possible we’ll resurrect the concept in the future,” they added. Its original domain now points to a crypto gambling site.

“We’re honored to bring Friendship List to life as an animated series,” Attanasio said in a press release. “Our artist-centered approach ensures these beloved characters and stories stay true to the author’s vision, while our Ink & Pixel production technology enables fast, high-quality production at scale which unlocks the ability to meet audiences where and when they enjoy content today.”
Toonstar has certainly proved it can make “content” for YouTube. Can it actually produce an enjoyable animat edshow? That’s another question entirely.
Iranian strikes have reportedly knocked out key AWS availability zones in Bahrain and Dubai, leaving parts of both regions effectively offline for an extended period and forcing Amazon to urge teams and customers to shift workloads elsewhere. “These two regions continue to be impaired, and services should not expect to be operating with normal levels of redundancy and resiliency,” an internal Amazon communication memo reads. “We are actively working to free and reserve as much capacity as possible in the region for customers, and services should be scaled to the minimal footprint required to support customer migration.” Big Technology reports: With the war now nearing its sixth week, Iran has made Amazon infrastructure in the Gulf an economic target and is now eyeing its peers. Amazon’s Bahrain facilities have been hit multiple times, including a Wednesday strike that caused a fire. And its facilities in the UAE also sustained multiple hits. The IRGC is threatening multiple other U.S. tech giants, including Microsoft, Google, and Apple.
Amazons infrastructure in Bahrain and Dubai each have three ‘availability zones’ or clusters of compute. Both Bahrain and Dubai have a zones that are “hard down” and and “impaired but functioning,” per the internal communication. “We do not have a timeline for when DXB and BAH will return to normal operations,” the internal post said.
Researchers have determined that Microsoft’s LinkedIn is scanning browser plug-ins and other information without permission, building user profiles using data that the company did not get permission to take.
Safari
A European advocacy group claims LinkedIn is probing browser extensions through its website code. Fairlinked e.V. published its “BrowserGate” report alleging LinkedIn detects installed browser extensions by probing for known identifiers through JavaScript. The group says the technique reveals personally identifiable information. Safari users are less likely to be affected by this specific mechanism, based on how extension detection typically works across browsers. Apple’s browser model limits fingerprinting surfaces, which reduces how much information sites can infer from installed extensions. Continue Reading on AppleInsider | Discuss on our Forums
Revel is heading into AXPONA 2026 (April 10-12) with a clear focus: the debut of its new Performa4 speaker series, expected to fall between $2,000 and $7,000 per pair. Under the HARMAN Luxury Audio Group umbrella, which also includes Arcam, JBL Synthesis, Lexicon, and Mark Levinson, Revel isn’t going after statement pricing here. Performa4 is aimed at the part of the market where most serious systems are actually built, and where the competition is crowded, well established, and not particularly forgiving.
Revel Performa4 Speaker Series
Revel’s Performa4 Series is a new loudspeaker line built on the company’s established approach to acoustic design and measurement. It reflects three decades of engineering focused on controlled performance and consistent results in real-world listening environments.
Revel’s Performa4 Series consists of two floorstanding models (F346 and F345), two bookshelf speakers (M146 and M145), a center channel (C245), and a powered subwoofer (B140). With multiple configurations available, the Performa4 lineup can be used in both two-channel music systems and multichannel home theater setups.
“At Revel, science is at the heart of everything we do. The Performa4 series represents the culmination of thousands of hours of research, development, and real-world testing. With our new 7th-generation Acoustic Lens waveguide and advanced DCC and MCC transducers, we’ve raised the bar for what’s possible in this class,” said Jim Garrett, Senior Director of Product Strategy and Planning at HARMAN Luxury Audio.

Acoustic Lens Waveguide, DCC and MCC Transducers Explained
The Performa4 series uses Revel’s Deep Ceramic Composite (DCC) and Micro Ceramic Composite (MCC) drivers, developed to improve stiffness while keeping mass low and reducing unwanted coloration.
Woofer and midrange drivers are built on cast aluminum frames designed with Finite Element Analysis to optimize airflow, control resonance, and maintain structural stability. Each driver also uses an inverted surround and integrated trim ring, which simplifies the front baffle and keeps the layout clean.
Revel’s 7th-generation Acoustic Lens waveguide is paired with a 1-inch DCC dome tweeter to improve integration with the midrange driver. The waveguide is designed to control dispersion more consistently across the listening area, while also supporting higher efficiency and lower distortion, including at off-axis positions.
Revel Performa4 Industrial Design
The Performa4 series adopts a clean, modern design that builds on Revel’s established cabinet approach without adding unnecessary complexity.

All models use magnetically attached grilles for a flush, hardware-free front panel, along with black accent detailing that keeps the visual profile consistent across the range. Cabinets are internally cross-braced to improve rigidity and reduce unwanted vibration.
Curved side panels are finished in real wood veneers, available in Natural Walnut and Black Walnut, offering a straightforward aesthetic that fits into both traditional and contemporary spaces.

The lineup is clearly built for flexibility. It can anchor a straightforward two-channel system or scale into a full home theater without mixing and matching across different voicings. That matters for buyers who want system coherence without overthinking every component swap.
What’s less clear is how much separation there is between models beyond size and output, and whether the subwoofer’s pricing will make sense for buyers building out a full system. There’s also no indication of built-in room correction or system-level integration features, which are becoming more common even in passive speaker ecosystems when paired with modern electronics.
This is for listeners who want a complete, measurement-driven speaker system in the $2,000 to $7,000 range without stepping into five-figure territory. Not entry-level, not cost-no-object—right in the middle where most serious systems live.

French fries are delicious, but notoriously unhealthy. A research team at the University of Illinois, however, has developed a deceptively straightforward method to keep the satisfying taste and crunch without requiring as much oil.
The cooking method combines traditional frying and microwave heating. Adding that microwave step could reduce the amount of oil used in the process, meaning you would absorb less fat with each bite. All the secrets to being able to cook fries in this way have been laid out in two studies published in Current Research in Food Science and The Journal of Food Science.
French Fries and Health
Although popular, fried foods contain high levels of fat, which is linked to several health problems, including obesity and hypertension. “Consumers want healthy foods, but at the time of purchase, cravings often prevail,” says Pawan Singh Takhar, author of one of the two studies. “The high oil content adds flavor, but it also contains a lot of energy and calories.”
It’s precisely with the goal of helping consumers make better food choices without feeling deprived that researchers have been trying to figure out how they can cook healthier french fries, achieving lower fat content without altering their taste and texture.

One of the main difficulties in frying, as the studies explain, is preventing the oil from penetrating the food. In the early stages of the french fry process, in fact, the pores of the potato are filled with water, leaving no room for the oil.
As cooking continues, however, the water evaporates, creating empty spaces that allow the oil to be drawn in by negative pressure. Much of the frying process takes place under that negative pressure, which essentially increases the tendency of the oil to be sucked into the fries
A New Wavelength
In the new study, therefore, the researchers tried to figure out how to extend the time in positive pressure and reduce the period under negative pressure. “When we heat something in a traditional oven, the heat transfers from the outside to the inside, but a microwave oven heats from the inside to the outside because the microwaves penetrate everywhere in the material,” Takhar says.
Specifically, microwaves cause water molecules to oscillate, resulting in increased vapor formation and thus shifting the pressure profile toward positive values that prevent the oil from being easily absorbed.

Microwave frying alone, however, would not produce the desired texture. “If only microwaving is used, the food turns out mushy,” says Takhar. In order to achieve crispness, frying and microwaving should be combined.
To achieve the right balance, the researchers carried out an experiment in which they specially designed a microwave fryer, monitoring temperature, pressure, volume, texture, moisture, and oil content of the chips. “We propose to combine the two methods in the same device. Traditional heating maintains crispness, while microwave heating reduces oil consumption,” the study concludes.

Microsoft is expanding its roster of in-house AI models, releasing a new speech-to-text system and making two existing models broadly available to developers for the first time.
The moves by Microsoft AI (MAI) are part of a broader effort by the company to expand its proprietary AI capabilities beyond its partnership with OpenAI, giving Microsoft more control over its own destiny in the competition against Google, Amazon, and others.
Microsoft announced MAI-Transcribe-1 on Thursday, a speech-to-text model that it says is the most accurate currently available. The company also released its existing voice and image generation models, known as MAI-Voice-1 and MAI-Image-2, for broad commercial use.
It’s Microsoft’s first major model release since a March reorganization, announced by CEO Satya Nadella, in which Microsoft AI CEO Mustafa Suleyman shifted away from day-to-day Copilot oversight to focus on frontier model development and superintelligence.
Suleyman told The Verge that the transcription model runs at “half the GPU cost of the other state-of-the-art models.” He told VentureBeat that the model was built by a team of just 10 people, and that Microsoft plans to eventually build a frontier large language model to be “completely independent” if needed.

Microsoft also recently hired former Allen Institute for CEO Ali Farhadi and other top AI researchers from the Seattle-based institute to further bolster Suleyman’s team, as GeekWire reported last week.
MAI-Transcribe-1 is designed to handle noisy real-world conditions such as call centers and conference rooms, and Microsoft says it is testing integrations with Copilot and Teams. Microsoft says it offers the best price-performance of any large cloud provider, competing directly with OpenAI’s Whisper and Google’s Gemini on the FLEURS benchmark.
In a blog post, Suleyman called the model “not just the most accurate but also lightning fast.”
MAI-Voice-1 generates natural-sounding speech and now lets developers create custom voices from short snippets of sample audio. MAI-Image-2 ranks in the top three on the Arena.ai image generation leaderboard and is rolling out in Bing and PowerPoint.

All three are available on the Microsoft Foundry developer AI platform and MAI Playground.
It’s been more than 50 years since NASA astronaut Harrison Schmitt took the famous Big Blue Marble photograph, showing a breathtaking vision of Earth taken aboard the Apollo 17 spacecraft on its way to the moon. Now, as the four-astronaut crew of the Artemis II mission heads toward the moon, more spectacular images are being released.
This stunning photo is perhaps the most reminiscent of the Big Blue Marble, showing Earth in all its fragile, lovely glory.
“That’s us!” NASA wrote in a post. The post also quoted astronaut Christina Koch as saying of Earth, “You guys look great.”

In a reply to questions on the post, NASA wrote, “Two auroras (top right and bottom left) are visible in this image. Zodiacal light (bottom right), is also visible, as well as airglow from Earth’s atmosphere.”

The total workforce at Tesla’s factory outside Austin, Texas shrunk dramatically last year as the company suffered its second straight year of declining sales, according to a compliance report spotted by Austin American-Statesman.
Tesla went from employing 21,191 people at the factory in 2024 to 16,506 workers in 2025, a drop of 22%. That’s despite the company’s global workforce growing from 125,665 employees in 2024 to 134,785 employees in 2025, according to filings with the U.S. Securities and Exchange Commission.
It’s not clear which teams were most affected by Tesla scaling back its workforce at the plant. But the company has become one of the largest employers in the Austin area since it opened the factory in 2022. CEO Elon Musk also relocated Tesla’s headquarters to the factory in 2021 before it opened. The company has invested more than $6.3 billion in the facility to date, according to the new report.
Though the AirPods Max 2 offer new features, a teardown of the headphones shows they’re still plagued by the same flaws of the original 2020 model.
Apple’s AirPods Max 2 gained the H2 chip, but not much else.
Apple’s AirPods Max 2 debuted on March 16, with their core feature being the H2 chip. With it, Apple’s high-end headphones gained capabilities like Adaptive Audio, Conversation Awareness, and gesture controls, among others. Active Noise Cancellation was improved as well. However, as explained in our review, the AirPods Max 2 are an iterative upgrade, that ultimately leaves something to be desired. New features and ANC enhancements aside, Apple effectively delivered more of the same with its AirPods Max 2. Continue Reading on AppleInsider | Discuss on our Forums
