How Does Increasing Engine Compression Ratio Affect Performance & Efficiency?
When comparing engine specs for nearly any combustion engine automobile, we see a number of variations available with differing outputs of horsepower and torque. We often have a choice of gasoline or diesel engines with a range of cylinder counts, arranged in inline or V formations.
If we really dig into the minutia of engine specifications, we’ll find a figure for compression ratio that looks something like 9.5:1. The compression ratio relates to the engine cylinder’s maximum volume with the piston at the bottom of its stroke compared to the volume at the top of the stroke where the combustion chamber is at its smallest.
Increasing the gasoline engine’s compression ratio, say from 9.5:1 to 10.5:1 means that the air-fuel mixture inside the cylinder gets compacted into a tighter package at the top of the stroke before ignition. For example, a 5.0-liter V8 engine contains about 0.625 liters per cylinder. At a 9.5:1 compression ratio, the cylinder’s 625 cc volume is squished into a 65.8 cc space, while at 10.5:1 that space shrinks to 59.5 cc.
YouTuber Engineering Explained tells us that increasing an engine’s compression ratio increases its thermal efficiency. Their calculations show the mathematical differences between 9.2:1 and 14.0:1 compression ratios give the higher compression engine a 6% power advantage. Hot Rod doesn’t share the math, but claims, in simple terms, that increasing the ratio by 1.0 within the range of common automotive compression ratios could deliver power gains between 2% and 4%. The magazine also points out that the published compression ratios relay theoretical static compression values, while dynamic compression ratios found in the real world are affected by factors such as valve timing.
Higher compression diesel engines are more efficient than gas
Diesel engines are more efficient than gas engines, thanks, in part, to their relatively high compression ratio. It also helps that diesel contains 15% more energy density than gasoline, but that’s a story for another time.
Diesel engines typically operate with compression ratios ranging from 14:1, which is the upper end of high performance gasoline engines, all the way up to 25:1. One way that diesel engines benefit from higher compression ratios is the heat generated by compressing air beyond 16:1. While a gasoline engine uses a spark to ignite the compressed gasoline mixture, a diesel engine relies on glow plugs for cold starts and high compression ratios to create temperatures up to 1,000 degrees Fahrenheit, more than enough to trigger combustion of its precisely-timed diesel fuel injections.
Generating such high compression ratios takes away some internal combustion engine efficiency. However, the increased cylinder pressure at the time of combustion translates into more power, primarily the torque for which diesel engines are known. In addition, the smaller combustion area of high compression engines (up to 16:1) allows the fuel load to burn quicker and more thoroughly, reducing ignition delay, reducing emissions, and increasing fuel economy.
Why don’t all engines use higher compression ratios?
If diesel engine efficiency and performance benefit from increasing compression ratios, why not use the same formula for gas engines? While it’s true that diesel engines exhibit greater efficiency and better performance with higher compression ratios than those typically found in gas engines, there is a point of diminishing returns, and like most mechanical things, there are tradeoffs.
Among the leading factors limiting compression ratios in gasoline engines are detonation and pre-ignition of the fuel load inside the cylinder. While internal combustion engines rely on the combustion of the fuel load during the engine’s power stroke to drive rotation of the crankshaft, the process must be controlled and precisely timed for optimum efficiency.
In a gasoline engine, combustion timing is ultimately controlled by the spark plug. If a gas engine develops excessive dynamic compression, whether from designed static compression ratios, forced air induction, or valve timing, higher internal cylinder temperatures could cause the air-fuel mixture to spontaneously combust sooner than designed, resulting in pre-ignition.
Detonation inside the cylinders is also caused by excessive heat and pressure. However, it occurs after the spark. Instead of a controlled fuel burn radiating through the combustion chamber from the spark plug located near the center, the fuel explodes, or detonates, violently.

After Cutting Down on ‘Side Quests,’ OpenAI Bought a Talk Show
OpenAI has spent the last few weeks seemingly trying to refocus on using AI for business instead of what execs dubbed “side quests,” dumping its AI video generator and its plans for an adult-themed chatbot. So this week, of course, the company announced it’s jumping into the media business.
OpenAI said it was acquiring Technology Business Programming Network, better known as TBPN, which runs a 3-hour show streamed on weekdays that delves into the biggest topics — and brings in the biggest names — in tech business.
(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)
OpenAI said it added TBPN to “help create a space for a real, constructive conversation about the changes AI creates,” Fidji Simo, CEO of AGI deployment at OpenAI, wrote in a message to employees shared by OpenAI. Simo said the company also wanted to take advantage of TBPN’s marketing prowess. “They have a strong pulse on where the industry is going, their comms and marketing ideas have really impressed me,” Simo said.
TBPN launched in October 2024 and has been compared to ESPN in how it covers tech — two guys at a big desk with news, analysis, commentary and banter about topics such as AI, crypto, startups and the defense industry. The show’s two hosts and co-founders, Jordi Hays and John Coogan, have had some of tech’s biggest names in studio — OpenAI’s Sam Altman, Meta’s Mark Zuckerberg, Microsoft’s Satya Nadella, entrepreneur Mark Cuban and Salesforce’s Marc Benioff, to name some.
The show is streamed live from 11 a.m. to 2 p.m. PT Monday through Friday on YouTube and X from the Ultradome, a studio on a Hollywood film lot. The show has 70,000 viewers daily and looks set to make more than $30 million in revenue this year, according to the Wall Street Journal.
TBPN co-host Hays acknowledged in a statement that the show has been “critical” of the AI industry.
“After getting to know Sam and the OpenAI team, what stood out most was their openness to feedback and commitment to getting this right,” Hays said. “Moving from commentary to real impact in how this technology is distributed and understood globally is incredibly important to us.”
In an era of fast-moving media consolidation, it’s a fair question — can TBPN keep saying what they really think, even if that ruffles OpenAI’s feathers? In her statement, Simo said OpenAI wants the show to maintain its “editorial independence.”
“TBPN will continue to run their programming, choose their guests, and make their own editorial decisions,” she said. “That’s foundational to their credibility, and it’s something we’re explicitly protecting as part of this agreement.”
Altman, OpenAI founder, echoed that sentiment with a posting on X. also calling TBPN his “favorite tech show.”
“We want them to keep that going and for them to do what they do so well,” Altman posted. “I don’t expect them to go any easier on us, am sure I’ll do my part to help enable that with occasional stupid decisions.”
The acquisition prompted some criticism and concern on social media as people wondered whether TBPN could really maintain editorial independence.
“Reporters doing accountability journalism are getting mowed down by mass layoffs & are now almost extinct — while the targets of their accountability reporting are giving hundreds of millions of dollars to pundits,” David Sirota, a longtime columnist and founder of the investigative news outlet The Lever, posted on X. “What stage of the media dystopia is this?”
TBPN will be under the supervision of OpenAI’s Chief Global Affairs Officer Chris Lehane, who joined the company in October 2024 and is the company’s main strategist in working with government officials. Decades ago, he worked in the White House of President Bill Clinton — helping to handle the Whitewater and Monica Lewinsky investigations — and as press secretary to Vice President Al Gore. Lehane also set up a procrypto super PAC called Fairshake that helped defeat anticrypto candidates during the 2024 elections and helped Airbnb battle housing regulations.

AI animation studio Toonstar will turn books into digital shows for HarperCollins
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.

Iran Strikes Leave Amazon Availability Zones ‘Hard Down’ In Bahrain and Dubai
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.

Microsoft's LinkedIn is scanning installed browser extensions without user permission
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.

Revel Performa4 Speaker Series Debut at AXPONA 2026 Priced From $2,000-$7,000
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.
Revel Performa4 Models
F346

The F346 is a 3-way floorstanding loudspeaker and the top model in the Performa4 series.
It uses three 6.5-inch (165mm) MCC woofers, a 6.5-inch (165mm) DCC midrange driver, and a 1-inch (25mm) DCC dome tweeter paired with Revel’s 7th-generation Acoustic Lens waveguide.
Dual rear-firing ports provide low-frequency extension, while dual 5-way binding posts support bi-amping or bi-wiring. The cabinet is fitted with solid aluminum feet and includes optional floor spikes for added stability.
The F346 is rated for a frequency response of 30Hz to 40kHz (±6dB), with 88dB sensitivity and a nominal impedance of 6 ohms. Recommended amplifier power ranges from 20 to 250 watts.
F345

The F345 is a 3-way floorstanding loudspeaker that shares the same core design as the F346, using smaller drivers in a more compact cabinet.
It features three 5.25-inch (130mm) MCC woofers, a 5.25-inch (130mm) DCC midrange driver, and a 1-inch (25mm) DCC dome tweeter paired with Revel’s 7th-generation Acoustic Lens waveguide.
Dual rear-firing ports support low-frequency output, while dual 5-way binding posts allow for bi-amping or bi-wiring. The cabinet includes solid aluminum feet with optional spikes for placement flexibility.
The F345 is rated for a frequency response of 36Hz to 40kHz (±6dB), with 87dB sensitivity and a nominal impedance of 6 ohms. Recommended amplifier power ranges from 30 to 225 watts.
M146

The M146 is a 2-way bookshelf or standmount speaker positioned in the middle of the Performa4 lineup.
It uses a 6.5-inch (165mm) MCC woofer paired with a 1-inch (25mm) DCC dome tweeter and Revel’s 7th-generation Acoustic Lens waveguide.
The crossover network incorporates air-core inductors, and dual 5-way binding posts support bi-amping or bi-wiring. Optional MFS4 floor stands are available for proper placement and listening height.
The M146 is rated for a frequency response of 43Hz to 40kHz (±6dB), with 86dB sensitivity and a nominal impedance of 6 ohms. Recommended amplifier power ranges from 15 to 200 watts.

The Bottom Line
Revel’s Performa4 series is a calculated move into one of the most competitive segments in loudspeakers. The combination of DCC and MCC driver materials, the 7th-generation Acoustic Lens waveguide, and consistent cabinet engineering across the range points to a focus on controlled dispersion, tonal consistency, and predictable in-room performance; areas where Revel has historically been very disciplined.
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.
At AXPONA 2026, the F346 will be demonstrated with an Arcam SA45 integrated streaming amplifier and CD5 CD player, which should give a clear sense of how the top model performs with both streaming and physical sources.
Pricing & Availability
The Revel Performa4 series begins shipping in April through authorized Revel dealers and custom installation installers. All models are available in Natural Walnut and Black Walnut wood veneer finishes.
Suggested retail pricing is as follows:
- F346 Triple 6.5-inch Floorstanding Speaker – $6,999/pair
- F345 Triple 5.25-inch Floorstanding Speaker – $4,999/pair
- M146 6.5-inch Bookshelf Speaker – $2,999/pair

Scientists Have Made a French Fry Breakthrough
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 releases new AI models to expand further beyond OpenAI

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.

‘You Guys Look Great’: Artemis Astronauts Share Earth’s Out-of-This-World Views
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.”
Another neat photo from the Artemis mission shows the planet neatly bisected, with one side lit up by the sun and the other in darkness.
This image of the Earth was taken by one of the Artemis II crew out the Orion’s window.
“You look amazing, you look beautiful,” Victor Glover, Artemis II pilot, said of the views of Earth in a video call with ABC News.
A view of the Earth from NASA’s Orion spacecraft as it orbits above the planet during the Artemis II test flight.
Another intriguing image shows part of the spacecraft itself. USA Today noted that “the image appears to show the bottom of Orion’s service module where its main engine and auxiliary thrusters are housed.”
We’re tracking the 10-day Artemis II mission with a regularly updated blog.
Keep an eye on NASA’s image repository to see the latest photos.
