This research demonstrates a new way to make carbon-based battery materials much safer, longer lasting, and more powerful by fundamentally redesigning how fullerene molecules are connected. Today’s lithium-ion batteries rely mainly on graphite, which limits fast-charging speed and poses safety risks due to lithium plating. These research findings mean progress toward safer electric vehicles, longer-lasting consumer electronics, and more reliable renewable-energy storage.

https://lifehacker.com/tech/ces-2026-i-tried-a-gaming-headset-that-can-read-your-mind

Before this CES, I thought gaming headsets had gotten about as complex as they ever would. How many improvements can you possibly make on speakers and microphones? Well, forget all that. Apparently, the future of gaming headsets is mind-reading.

In a private demo with a colleague from IGN this CES, I tested out a collaboration between HP’s HyperX gaming brand and brain-computer interface company Neurable. Neurable’s been at CES before, but most of its work has been in the defense and enterprise sectors. The idea behind the brand is specifically aimed at helping you nail down your focus, and now, Neurable thinks it can use that to help gamers.

Here’s how it works. Before trying on the Neurable x HyperX headset, I did a quick run-through in a target shooting game, where I shot down 30 targets with a 547ms response time. Then, I got guided through a focus program called Prime. This showed a cloud of dots on the screen, and I was told to do whatever I needed to do to focus up. I decided to stare into the distance and count, and in about 90 seconds, the dots had shrunken down into a small orb and I was "primed." Neurable also suggested focusing techniques like repeating a word in your head over and over, or following one of the dots as it moved about the screen, but these didn’t work for me.

Than, I did the shooting test again. Theoretically, I should have been better, but I actually scored slightly worse this time—a 559ms response time.

Still, that response time isn’t terrible, and your mileage may vary. It might just have been that I was already really locked in before priming, and my colleague actually reduced her response time by about 40ms after priming.

If all of that optimization sounds really nitty-gritty, well, yeah. This is aimed at esports players and streamers, where every (mili)second counts.

And that’s probably where the headset’s coolest feature comes in for me. Alongside Prime, Neurable and HyperX are also working on an overlay plugin for streamers that can show their focus level on screen. You can display this as a speedometer, or as that cloud of dots, or even as a progress bar that shows whether you’re "on tilt" or not. It should make for some pretty fun interactions with viewers, and play well with existing plug-ins, like eye trackers that show where a streamer is looking.

Plus, my slightly worse response time after priming wasn’t totally useless. Neurable said the headset could be used to help you "practice choking," where you psych yourself up shortly after locking in and end up worse off. I thought that maybe sounded like marketing spin, but my colleague, a high-level raider in World of Warcraft, said it would have real use for her.

It’s still just a concept for now, but it’s exciting to see this kind of tech getting ready to hit the mass market. What also sets Neurable apart is how portable it is. Unlike other brain-computer interfaces, this just looks like a normal headset, and all the contacts are just stored in the earcups. There’s no need for a giant helmet with discs and wires attached to it, which is thanks to Neurable’s expertise in AI. The company says that using such a compact form factor does result in getting a small amount of data, and a lot of junk data, but thanks to an on-device AI model, it’s easily able to detect trends in your focus and translate them into something usable.

That seemed to be true in my demo, which at the end of the day, kind of felt like a guided meditation with real-time feedback. You could use this for more than gaming, but it’s a clever use case for digital mind-reading, and the streaming plugins really take the cake, helping solidify the concept into a clear product with a concrete goal and target audience.

It’ll take a while for the gaming version of Neurable’s tech to be ready, although the company said it hopes to get it out this year. In the meantime, you can buy an ultra-luxury headset with Neurable’s mind-reading built in, although it’s currently on pre-order and will set you back $500. It also won’t come with Prime or that streaming plugin, although because those are based in software, that could change in the future.

The Best of Both Worlds? Not Always

A plug-in hybrid vehicle (PHEV) offers several advantages, including lower fuel costs and reduced emissions, without requiring buyers to make a full transition to an all-electric vehicle. However, apart from their apparent non-eco-friendliness, PHEVs experience roughly 80 percent more problems than their purely internal-combustion counterparts, according to Consumer Reports (CR). This figure raises questions about the technology’s long-term reliability and reputation.

In its latest annual survey – based on responses from the owners of about 380,000 vehicles from the 2000 through 2025 model years, and a few early 2026 models – CR breaks down which PHEV models across various segments contributed most to that disparity, offering buyers more detailed insight as they consider their next vehicle purchase.

CR’s 2026 PHEV List

The Ford Escape PHEV ranks as the least reliable among compact SUVs, a segment that also includes the Toyota RAV4 Prime and the Mitsubishi Outlander PHEV. Owners participating in the survey cited a wide range of issues specific to the Escape PHEV, including EV battery replacement, battery cooling, EV charging, and electric accessories. In addition to PHEV-related concerns, respondents also reported non-electrification-related problems involving the steering and suspension, as well as the climate control system.

Stellantis appears multiple times on the list, starting with the Jeep Wrangler and Grand Cherokee using the 4xe, the automaker’s plug-in hybrid technology paired with a 4×4 drivetrain. According to CR, all reported issues were tied directly to the 4xe system, including problems with the hybrid system itself, EV battery stalling, and the electric motor. One owner claimed their vehicle was “bricked for nearly six months,” while another reported making eight dealer visits to address recurring hybrid-related failures.

Regulators have also taken notice. NHTSA has been involved in multiple 4xe actions, including a recall tied to loss of drive power issued earlier this year. Separately, the non-4xe Grand Cherokee was also cited in Consumer Reports’ latest survey of the most unreliable SUVs.

At the larger end of the spectrum, the Mazda CX-90 PHEV reportedly ranks as the least reliable among full-size SUVs. This finding mirrors CR’s 2026 Reliability Brand Rankings, in which Mazda dropped from the top 10 to 14th overall. The CX-90 PHEV was flagged for a long list of problems, including issues with the EV battery, electric motor, and engine electrical system. Owners also reported faults involving the transmission (both major and minor), drivetrain and fuel system, climate controls, steering and suspension, brakes, electric accessories, body hardware, in-car electronics, noises/leaks, and paint and trim quality.

One owner summarized their experience by saying their CX-90 PHEV suffered a “hybrid malfunction that causes the car to seize. It will not start, go into gear, or charge.”

The Cost of Complexity

In the luxury segment, the Volvo XC60 PHEV earns similarly unwanted recognition. The report cites issues affecting electrical accessories, the climate system, the drivetrain, the electric motor, and the EV battery. One owner noted that after just a month of ownership, their XC60 PHEV “would not go over 26 mph and went into snail mode,” a term commonly used to describe limp mode, where power output is reduced to prevent further damage.

Another Stellantis model is the Chrysler Pacifica PHEV, though, to be fair, it remains the only minivan with a plug-in hybrid powertrain currently sold in the U.S. For context, the Toyota Sienna and Kia Carnival are offered only as conventional hybrids. At the same time, the Honda Odyssey remains purely internal combustion, despite its Japan-market counterpart using a dual-motor hybrid setup similar to that found in the Civic and Accord. According to CR, Pacifica PHEV owners reported issues involving the transmission, engine, in-car electronics, electric accessories, EV charging, and EV battery cooling.

With automakers like Volvo now scaling back earlier all-electric timelines, this report suggests there is still considerable work to be done to ensure that multi-powertrain strategies – particularly those involving PHEVs – can deliver the reliability consumers expect.

https://www.autoblog.com/news/china-is-putting-a-hard-limit-on-how-much-energy-evs-can-use

Drawing the Line

China is set to impose the world’s first hard cap on electric-vehicle energy consumption beginning next year. According to CarNewsChina, newly produced EVs weighing around two tonnes (about 4,400 pounds) will be limited to 15.1 kWh per 100 km, which translates to roughly 139 MPGe under Environmental Protection Agency (EPA) metrics. That efficiency target places the rule in roughly the same territory as the Tesla Model Y.

Officially titled Energy Consumption Limits for Electric Vehicles Part 1: Passenger Cars, the regulation requires all newly made EVs to meet the new efficiency threshold. Models that fall short will force automakers to carry out technical revisions to bring them into compliance, potentially affecting the use or development of larger battery packs. The report also notes that EVs failing to meet the mandatory energy-consumption limits will lose eligibility for tax exemptions.

When Bigger Stops Being Better

The new cap is particularly stringent when viewed through a U.S. lens, where EVs are often developed to be larger, heavier, and more powerful in response to consumer preferences. A clear outlier under China’s framework would be the GMCHummer EV, which is widely regarded as one of the least efficient EVs on sale today. The Hummer EV carries an EPA efficiency rating of roughly 53 MPGe while tipping the scales well over 8,600 pounds.

Chinese regulators argue that the tighter standard will produce tangible benefits. The updated rule tightens energy-consumption requirements by approximately 11 percent, which authorities say could result in an average 7-percent increase in driving range for EVs using the same battery capacity. In addition, the regulation is intended to accelerate the adoption of energy-saving technologies, pushing manufacturers toward more efficient motors and EV architectures.

Setting the Stage for a New EV Reality

The new cap applies only to battery-electric vehicles, so hybrids and plug-in hybrids – like the Toyota RAV4 Prime – are exempt. CarNewsChina also reports that many EVs from Geely and BYD, two of the top-selling EV brands in China, already comply with the new limits and are expected to require minimal or no changes.

While the regulation applies specifically to China, its influence could extend well beyond the domestic market. As the world’s largest EV market, China sets one of the most influential benchmarks for global EV development, meaning automakers hoping to compete there may need to rethink vehicle size, weight, and efficiency. Over time, that pressure could reshape global EV strategies – effectively discouraging oversized, inefficient EVs from entering the market. The new regulation is scheduled to take effect on January 1, 2026.

https://www.autoblog.com/news/texas-rolls-out-digital-speed-limit-signs

Drivers in the state of Texas can no longer assume they know the roads well enough to stick with the speeds they’ve always done, as new variable speed limits are rolling out across the state. Digital speed limit signs are being installed to change the legal limit on certain roads after a deadly February 2021 crash, originally attributed to icy roads, raised safety concerns. A multi-car pileup took place on I-35W during an intense winter storm, and temperatures had fallen below freezing for over 36 hours with speed limits remaining at 75 mph, according to the National Transportation Safety Board’s report. Six died, and 36 were injured in an accident that spanned 1,100 feet on the North Tarrant Expressway.

Expect to See More Digital Signs Across the State

Naturally, a vehicle’s braking distance and handling change when the weather turns inclement and reduces traction, and these new variable limits aim to reduce the risks that drivers face when their vehicles become more difficult to control. The initiative began with a pilot program two years ago, after legislators approved the use of variable speed limits to change posted limits depending on road conditions. The idea is that people will be encouraged to drive more slowly when the weather turns bad, when there’s traffic up ahead, or when other hazards present themselves (roadworks, accidents, et cetera). Similar signs already exist in Colorado, Washington, Oregon, Minnesota, Florida, and several other states, using real-time data to adjust the limits in the hopes of improving safety and flow.

"If we’re not able to alter or modify the speed limit to reflect the current conditions, safety is in jeopardy," State Representative Terry Canales, author of the bill to authorize variable speed limits, told the Texas Tribune. The signs will start to appear on freeways already connected to the Intelligent Transportation System, which uses cameras and sensors to monitor conditions, readjusting the limits once conditions are deemed safe, reports Chron.

Meanwhile, in Arizona…

As Texas works to ensure speed limits suit the conditions, a new bill proposed by Arizona State Rep. Nick Kupper could remove them entirely — but only at certain times. The Reasonable and Prudent Interstate Driving (RAPID) Act endeavors to give the Arizona Department of Transportation the authority to create "derestricted speed zones" on certain rural interstates during daylight hours, with an 80-mph limit remaining in place after dark. The derestriction would also not apply to commercial vehicles, including semi trucks, and urban areas with populations over 50,000 people would remain restricted, too. A long list of requirements would need to be met, but like the implementation of variable limits in Texas, the idea is that this would help improve traffic flow and safety, though some argue that irresponsible individuals would abuse the Autobahn-like measure.

https://www.autoblog.com/news/toyota-says-americas-evs-could-power-40-nuclear-reactors

The Irony of Toyota’s Big Announcement

Toyota just dropped an eye-opening postulation about battery electric vehicles with vehicle-to-grid capabilities. The manufacturer says the roughly four million EVs currently on American roads could collectively pump approximately 40,000 megawatts back into the power grid, equalling what 40 nuclear reactors generate. Your idle EV could help stabilize grids by leveling spikes in demand, limit outages, and technically even reduce your energy costs.

The only issue with this is that Toyota is championing V2G technology without currently offering a single production vehicle in North America that supports bidirectional charging. A Japanese-spec bZ4X prototype equipped with V2G has been doing the rounds for the pilot, but American buyers can’t buy it. Toyota is essentially promoting technology they haven’t yet committed to selling.

Why Bidirectional Charging Is a Big Deal 

This is how it works in theory: EV owners charge batteries during cheap off-peak nighttime hours, then either power their homes directly or sell stored energy back to the grid during expensive peak periods. Think of it like the stock market: buy low and sell high, though that isn’t the prime goal here.

Bidirectional charging can stabilize the grid during extreme weather or outages. When thousands of vehicles act as distributed storage, utility companies can avoid firing up expensive backup generators during demand spikes. What’s more interesting is vehicle-to-home and vehicle-to-load technology, which allows drivers to directly give energy back to their homes or appliances.

Final Thoughts

While Toyota experiments, other manufacturers have already delivered. The Ford F-150 Lightning’s 9.6 kW of V2H power is enough to run an average house for three days during outages. Nissan pioneered this space in 2013 with the Leaf, theoretically letting owners earn money by feeding power back during peak demand. General Motors standardized V2H charging across its 2024 electric lineup, while Hyundai and Kia are running European pilot programs with the Ioniq 5. Tesla‘s Cybertruck now delivers 11.5 kW of home backup through its Powerwall system.

Despite Toyota’s grand projections, implementation faces obstacles. Most grids aren’t configured for bidirectional charging, and the home charging equipment costs thousands of dollars, turning off users who own vehicles with V2G capability. Then there’s battery degradation from working those extra cycles, and the fact that the regulatory framework governing electricity sales varies wildly from state to state. While the current costs associated with setting up bidirectional charging still skew the economics against it, the time when it all makes sense and Toyota’s vision comes to life isn’t so far off.
