With its sleek design and groundbreaking aerodynamics, the Airbus RACER isn’t just a prototype—it’s a symbol of Europe’s commitment to clean aviation.

Brice Makinadjian and Stephane Deport, both engineers at Airbus Helicopters, looked on proudly as a sleek blue-and-white helicopter zipped over the crowds at the Paris Airshow in June 2025.

Slicing through the air was the Airbus RACER (Rapid and Cost-Effective Rotorcraft), an advanced prototype designed to be faster, quieter and more fuel-efficient than conventional helicopters.

This high-speed, low-emission rotorcraft is redefining helicopter flight by blending the speed of an airplane with the agility of a rotorcraft—all while slashing CO2 emissions by approximately 25% compared to a conventional helicopter of the same weight category.

How it started: A European team effort

The RACER’s roots go back to the EU’s Clean Sky 2 program (2014–2024), the largest research program for aviation ever launched in Europe.

This public-private collaboration between the European Commission and the European aeronautics industry funded the development of innovative, cutting-edge technologies to reduce the aeronautics sector’s environmental impact.

The support provided under Clean Sky 2 made it possible for the various components of the RACER—such as aerodynamics, engine integration and rotor systems—to be incrementally refined before being tested together in the demonstrator built by Airbus, a leading European aerospace company.

“This partnership has been fundamental,” said Makinadjian. “We could not have done this without European collaboration and support.”

The development of the prototype has involved over 40 European companies and research organizations from 13 countries. “We have access to the best of Europe,” said Makinadjian. “It is the European spirit at its finest.”

Cleaner future for European skies

The RACER is also part of Europe’s mission to make flying greener. Under the European Green Deal, the EU has pledged to become climate neutral by 2050, and aviation is no exception.

The EU’s Sustainable and Smart Mobility Strategy sets the goal of having zero-emission aircraft ready for market by 2035. This would mark a major step toward climate-neutral aviation and a cleaner future for European skies.

Why does this matter? As Axel Krein, executive director at the Clean Aviation Joint Undertaking (2025–2035)—Clean Sky 2’s successor—pointed out, aviation is a powerhouse for Europe’s economy. It supports 13.5 million jobs and contributes over €1 trillion to the European economy. That is 3.6% of all jobs and 4.4% of Europe’s GDP.

For Krein, the importance of the RACER demonstrator for Europe is evident. Such new designs will help secure Europe’s aerospace leadership in the future.

“Currently, Europe has a market share of 58% of new civil aircraft worldwide, so Europe’s aviation leadership is strong. But it is not guaranteed,” he said. “Global competition and geopolitical shifts are threatening this leadership.”

Stealth and speed

After over 10 years in development, the new technologies being showcased in the RACER prototype could become an essential part of helicopter design over the coming decade.

The RACER’s sleek aerodynamic design and side-mounted lateral rotors give it a cruising speed of over 440 km/h—over 50% faster than regular helicopters.

One of the factors is the reduced air and wind resistance, or drag, as it moves through the air. This is 2.5 times lower than in other helicopters of the same weight.

“We have a lower drag than the smallest helicopters on the market today,” said Makinadjian.

The main rotor was redesigned, reducing its speed, to increase stability. At the same time, two wings were added at the sides with lateral rotors to provide forward thrust.

This means that the RACER can fly like an airplane in certain flight phases, using its wings and lateral rotors to glide forward, making it effectively a cross between a helicopter and a fixed-wing aircraft.

Eco-mode

The innovative Eco Mode system is another standout feature, similar to the start-stop function in modern cars, that will soon be tested on the RACER. Developed by Safran, the Eco Mode involves putting one of the two engines on standby during cruise flight, allowing the other to operate at a more optimal and energy-efficient power setting.

This mode of operation not only reduces CO₂ emissions and fuel consumption by around 15%, but also increases the distance that can be covered by the helicopter.

“We can fly at 350 km/h on only one engine,” said Deport. “But we also need to be able to restart the other engine instantly to keep it safe.”

Overall, the improved aerodynamics and allow the RACER to use 25% less fuel than slower, conventional helicopters. As the team gears up to begin testing the Eco Mode feature, they expect to achieve even more fuel savings.

In addition to commercial transport, the developers predict that the RACER could be ideal for emergency medical services and search and rescue operations because of its speed and efficiency.

“Emergency response helicopters need to be fast and noise reduction is key to perform operations close to inhabited areas,” said Makinadjian.

From cars to choppers

A total of 40 partners collaborated on the creation of the RACER. One unexpected partner in the RACER’s journey was KLK Motorsport, an SME from Germany specialized in high-performance mechanical engineering, lightweight structures and advanced composite materials.

Better known for its expertise in car racing rather than aerospace, KLK co-developed the RACER’s canopy—the sleek, enclosure over the cockpit that needs to handle airflow efficiently to optimize aerodynamics.

Their involvement highlights one of the RACER’s greatest strengths: the wide collaboration that went into its development, which brought in the expertise of major industry players, but also specialized SMEs and leading research organizations.

“Working with people outside aerospace is invigorating,” said Makinadjian. “The creation of new parts for car racing moves at lightning speed. When we told them they had five years to develop a ‘very innovative and light’ canopy, they were surprised,” he laughed. “In racing, everything needs to be delivered yesterday.”

Flying into the future

The RACER prototype took to the skies for the first time in April 2024. More than a year on, it has logged around 35 hours of flight time, but there is plenty more testing ahead.

Despite their deep involvement in the design, engineers Makinadjian and Deport have yet to fly in the RACER themselves. “Only eight people, besides the , have been able to,” said Makinadjian. “We’re still on the waiting list.”

Tests continue at the Airbus Helicopters’ headquarters in Marignane, near Marseille in southern France. Early results are encouraging. But Makinadjian and Deport are still working hard to finetune the technical details. For them, this is just the start.

What excites them most is simply being part of the journey. “If you’re an aerospace engineer, this kind of project only comes along once in a lifetime,” said Makinadjian. “To go from nothing to seeing your design take flight—it’s magical.”

As the RACER continues its test flights, it is not just pushing the boundaries of rotorcraft speed—it is charting the course for a new era of more fuel-efficient, smarter aviation in Europe.

I Tested Garmin Watches for a Decade While Hiking, Biking, and Climbing. Here’s What You Should Buy

I Tested Garmin Watches for a Decade While Hiking, Biking, and Climbing. Here’s What You Should Buy


Last year, Garmin introduced a Pro version that incorporates the inReach’s satellite communications savvy. Not only does it cost at least $400 more than the Apple Watch Ultra and $200 more than the regular Fenix 8, but you also have to pay for the inReach subscription plan, which has several tiers and ranges from $8/month to $50/month depending on whether you want features like unlimited texting or sending photo messages.

What you get for this mind-boggling price is a sports watch that can do anything and everything. It has best-in-class battery life (every Fenix can last for weeks on a single charge, and up to a month with solar charging) and features like the depth sensor from Garmin’s Descent line, which means this watch works as a full-on dive computer for scuba and free diving. It has a microphone and speaker for basic voice commands (although no onboard cellular connectivity), the surprisingly useful built-in LED flashlight, and Garmin’s signature built-in topographic maps, 24/7 health monitoring, and tracking for over a hundred different activities.

I’ve taken the 51-mm version on pretty much every outdoor sport—snowboarding, trail running, mountain biking, and rock climbing. Every time I use it, its capabilities far outclass my own. I have irritated many a fellow climber by attempting to track route difficulty, duration, and falls while integrating my Body Battery metrics and so on. The danger is always that you’ll spend more time fiddling with your Garmin Fenix 8 than you do with your actual sport. I have the version with the sapphire glass face and the titanium bezel, and have smashed it into rock faces with nary a scratch. If you’re up for paying the price and want a good-looking watch that will last forever (I have friends who are still wearing their Fenix 5s and 6s, and honestly, they’re fine), this is the one to get.

Best Running Watch

The Garmin Forerunner series launched in the early 2000s and has become the quintessential runner’s watch. Like all Garmins, the Forerunner comes in a range of price points, each offering different features. Last year, Garmin released the Forerunner 570 ($550), a midrange model with no LED flashlight or onboard maps, and the Forerunner 970 ($750), which is the premium version. Before I go into detail about why the Forerunner 970 is the best option, I should also say that I have tested many previous Garmin Forerunners at various price points. If you’re not a triathlete, the older Forerunners are still worth considering, and the entry-level $200 Forerunner 165 is aimed explicitly at runners, instead of including triathletes as the more expensive models do.

Save Up to 40% With These Acer Promo Codes and Discounts


Acer is one of the top largest PC manufacturers in the world, perhaps best known for its gaming line and budget-friendly options. If you’ve already got your eye on an Acer product like a laptop or monitor, and are shopping at the company’s online storefront, you should be using one of these Acer promo codes and coupons to save some cash on your purchase.

Save 40% on Accessories When You Build an Acer Bundle

If you’re buying from Acer, you’re most likely shopping for either a desktop PC or laptop. With this discount, you can get a really solid deal on accessories if you bundle it with a mouse, laptop bag, or headset. When you go to purchase a PC, just click “Build Bundle” and you’ll see some of the eligible options, all of which are reduced by 40%. The Nitro Mechanical Keyboard, for example, goes from $50 to just $30. That 40% is a real discount, too, as that same keyboard costs $50 on Amazon when I checked.

Beyond peripheral add-ons, you can also save 10% off Acer Care Plus extended service plans or McAfee LiveSafe antivirus subscriptions. You can bundle up to five products together to save the most money. If you’re headed off to college (or have a kid in the family), a bundle like this can get you everything you need for a gaming or studying setup on the go.

Shop Rotating Weekly Deals on Monitors and Gaming Gear

Acer’s PC gaming offerings come in either the flagship Predator brand or the budget-tier Nitro. Acer offers rotating weekly deals on everything from monitors to gaming laptops, some of which are my favorites that I’ve tested in their given category. The Acer Nitro V 16, for example, was a budget gaming laptop that I recommended quite a lot last year because of its incredible price. The one I tested was the entry-level version with an Nvidia RTX 5050 inside, but Acer has the RTX 5060 model in its own storefront. It’s $100 off right now at $1,200, which comes with 16 GB of RAM and a terabyte of storage. In fact, it’s only $30 more than the RTX 5050 model, despite offering a significant jump in gaming performance. These discounts are reflected right on the product pages, so there’s no promo code, discount code, or coupon code required.

Acer has a wide selection of monitors available, too, whether that’s a massive 49-incher or a more modest 27-inch gaming workhorse. One of my favorite discounts I saw right now was the Acer Nitro XV2, a 27-inch 1440p display with a 300 Hz refresh rate. It’s 44% off at the time of writing, bringing the price down to just $250. Because these discounts are swapped out on a weekly basis, it’s worth checking back to see if the product you’re eyeing has a new discount.

Select Customers Can Get 15% Off Their Purchase

Acer also offers a number of added discounts at checkout, including 15% off for students. Students will need to verify through Student Beans or SheerID. Because a lot of the devices Acer offers are budget-friendly, they can be attractive for students, and the extra 15% off is the icing on the cake.

We tested the Acer Swift 16 AI last year and really enjoyed the high-resolution, OLED screen and impressively quiet performance. Acer has the smaller version of this same laptop available, the Swift 14 AI, which is currently $150 off. You also might check out the Acer Chromebook Plus 514, a laptop we liked quite a bit when we reviewed it in 2024.

Acer offers this same 15% discount for active duty military, veterans, and their families. It also applies to healthcare professionals, which can be verified through its healthcare discount portal.

AI Research Is Getting Harder to Separate From Geopolitics

AI Research Is Getting Harder to Separate From Geopolitics


The world’s top AI research conference, the Conference on Neural Information Processing Systems—better known as NeurIPS—became the latest organization this week to become embroiled in a growing clash between geopolitics and global scientific collaboration. The conference’s organizers announced and then quickly reversed controversial new restrictions for international participants after Chinese AI researchers threatened to boycott the event.

“This is a potential watershed moment,” says Paul Triolo, a partner at the advisory firm DGA-Albright Stonebridge who studies US-China relations. Triolo argues that attracting Chinese researchers to NeurIPS is beneficial to US interests, but some American officials have pushed for American and Chinese scientists to decouple their work—especially in AI, which has become a particularly sensitive topic in Washington.

The incident could deepen political tensions around AI research, as well as dissuade Chinese scientists from working at US universities and tech companies in the future. “At some level now it is going to be hard to keep basic AI research out of the [political] picture,” Triolo says.

In its annual handbook for paper submissions, issued in mid-March, NeurIPS organizers announced updated restrictions for participation. The rules stated that the event could not provide services including “peer review, editing, and publishing” to any organizations subject to US sanctions, and linked to a database of sanctioned entities. It included companies and organizations on the Bureau of Industry and Security’s entity list and those on another list with alleged ties to the Chinese military.

The new rules would have affected researchers at Chinese companies like Tencent and Huawei who regularly present work at NeurIPS. The database also includes entities from other countries such as Russia and Iran. The US places limits on doing business with these organizations, but there are no rules around academic publishing or conference participation.

The NeurIPS handbook has since been updated to specify that the restrictions apply only to Specially Designated Nationals and Blocked Persons, a list used primarily for terrorist groups and criminal organizations.

“In preparing the NeurIPS 2026 handbook, we included a link to a US government sanctions tool that covers a significantly broader set of restrictions than those NeurIPS is actually required to follow,” the event’s organizers said in a statement issued Friday. “This error was due to miscommunication between the NeurIPS Foundation and our legal team.”

Before they reversed course, the conference organizers initially said that the new rule was “about legal requirements that apply to the NeurIPS Foundation, which is responsible for complying with sanctions,” adding that it was seeking legal consultation on the issue.

Immediate Backlash

The new rule drew swift backlash from AI researchers around the world, particularly in China, which produces a large quantity of cutting-edge machine learning papers and is home to a growing share of the world’s top AI talent. Several academic groups there issued statements condemning the measure and, more importantly, discouraging Chinese academics from attending NeurIPS in the future. Some urged Chinese academics to contribute instead to domestic research conferences, potentially helping increase the country’s influence in relevant science and tech fields.

The China Association of Science and Technology (CAST), an influential government-affiliated organization for scientists and engineers, said Thursday that it would stop providing funding for Chinese scholars traveling to attend NeurIPS and would use the money instead to support domestic and international conferences that “respect the rights of Chinese scholars.”

CAST also said it will no longer count publications at the 2026 NeurIPS conference as academic achievements when evaluating future research funding. It’s unclear if the organization will reverse course now that NeurIPS has walked back the new rule.
