A few months from now, a NASA spacecraft called the Mars Reconnaissance Orbiter (MRO) will begin its 20th year of observing the Red Planet from above. And, like most 20-year-olds on Earth, MRO’s camera roll is absolutely packed.According to NASA, MRO has just taken its 100,000th photo of the Martian surface using its HiRISE camera. Put another way, that’s an average of 5,000 photos a year, 417 photos a month, or about 14 a day every day since March 2006.The new milestone image, snapped on Oct. 7, shows a shadowy wasteland of mesas, craters and dunes known as Syrtis Major.…

Since I’m fascinated by new display technologies and by improving image quality, I’ve never been a fan of home projectors. Projectors lack the image quality compared to good TVs and monitors, and they’re pretty needy. Without getting into the specific requirements of different models, you generally want a darker room with a large, blank wall for a projector to look its best. That can be a lot to ask for, especially in small, densely decorated homes like mine. That said, a projector can be a space-efficient alternative to a big-screen TV or help you watch TV or movies outside. A…

As we approach the new year, you might find yourself thinking a lot about your goals for 2026. Lots of folks go into January big ambitions to get in shape and keep to a regular fitness routine, but the reality many also drop any health changes they’re trying to make by February. It’s a motivation and discipline issue, but you can help yourself look forward to your time in the gym or time running outdoors with the right tools. I’m talking about a good pair of headphones. I like to use my time running to catch up on podcasts that…

Over 10,000 years of domestication, cats have learned to meow to get exactly what they want from their human servants. Now, researchers in Turkey have found that cats greet men far more vocally than they do women — and this could be another way they manipulate us to get the attention they deserve.The new research reveals “cats’ ability to categorize bonded individuals and modulate their responses,” said study co-author Kaan Kerman, principal investigator of the Animal Behavior and Human-animal Interactions Research Group at Bilkent University in Turkey. “This shows that cats are not automata and possess cognitive abilities that enable…

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…
