Compression ratios At issue is the engines’ compression ratio, which compares the volume of the cylinder when the piston is at top dead center with the volume when the piston is at its closest to the crank. Under the 2014–2025 rules, this was set at 18:1, but for 2026 onward, it has been reduced to 16:1. This is measured at ambient temperature, though, not while the engine is running. A running engine is hotter—much hotter—than one sitting at ambient, and as metals heat up, they expand. The engines have very short throws, so it doesn’t take much expansion to increase…
Yesterday, it was confirmed that Vince Zampella, the head of Respawn also known for his work as a lead developer on Call of Duty and Battlefield, was killed in a car accident on Sunday, December 21. Zampella had a storied career, co-founding Infinity Ward in 2002, which would go on to spend the next two decades creating Call of Duty games. After a messy breakup with Activision, he went on to found Titanfall developer Respawn Entertainment and was eventually made the lead of the Battlefield franchise in 2021. We are heartbroken by the loss of Vince Zampella, a creative leader…
A new brain-machine interface (BMI) uses light to “speak” to the brain, mouse experiments show.The minimally invasive wireless device, which is placed under the scalp, receives inputs in the form of light patterns, which are then conveyed to genetically modified neurons in brain tissue.In the new study, these neurons activated as if they were responding to sensory information from the mice’s eyes. The mice learned to match these different patterns of brain activity to perform specific tasks — namely, to uncover the locations of tasty snacks in a series of lab experiments.

For the second time this month, a Chinese rocket designed for reuse successfully soared into low-Earth orbit on its first flight Monday, defying the questionable odds that burden the debuts of new launch vehicles. The first Long March 12A rocket, roughly the same height and diameter of SpaceX’s workhorse Falcon 9, lifted off from the Jiuquan Satellite Launch Center at 9:00 pm EST Monday (02:00 UTC Tuesday). Less than 10 minutes later, rocket’s methane-fueled first stage booster hurtled through the atmosphere at supersonic speed, impacting in a remote region about 200 miles downrange from the Jiuquan spaceport in northwestern China.…
Honor is clearly thinking beyond the usual smartphone rivals with its upcoming Robot Phone. The idea alone shows just how far the company is willing to stretch what a phone can be. We already know the Honor Robot Phone is real. The company showed a working prototype at the Honor User Carnival in China last month. And at first glance, the device looks like a regular phone. However, the rear camera module hides an unusual piece of hardware. It has a whole mechanical camera arm that can move on its own. Never seen anything like this, but it’s coming next…
Games don’t shut up anymore. At least most of the big-budget ones. There are potentially lots of reasons for that but it mostly sucks. Not sure what I’m talking about? Look no farther than this Unreal Engine 5 fan render of what a gritty Mario game might look like that’s going viral again thanks to a perfect set of new voiceovers. It’s actually broken up into two videos. The first was shared earlier this month on Instagram on by voice actor and cosplayer ryanstewartvo. It shows Mario navigating a dark, linear jungle environment at night with question blocks, Goombas, and…
Around 18,000 years ago, ice age people in what is now Ukraine likely weathered the extremely harsh climate by building parts of their shelters out of mammoth bones, a new study finds.The mammoth dwellings show how communities thrived in extreme environments, turning the remnants of giant animals into protective architecture,” the archaeologists wrote in a statement.The bones were originally found near the village of Mezhyrich, about 70 miles (110 kilometers) southeast of Kyiv. When it was excavated between 1966 and 1974, the archaeological team at the time found the mammoth remains arranged in such a way that suggested they had…
DJI sent numerous requests to the US government to audit its devices in hopes of avoiding a ban, but the federal ban was ultimately enacted based on previously acquired information, The New York Times reported this week. The news means that Americans will miss out on new drone models from DJI, which owns 70 percent of the global drone market in 2023, per Drone Industry Insights, and is widely regarded as the premium drone maker. People can still buy drones from US companies, but American drones have a lackluster reputation compared to drones from DJI and other Chinese companies, such as…
