Seven major automakers have banded together to create a new charging network in North America, with an eventual target of 30,000 high-powered charge points near urban and highway locations. The companies involved with the venture include BMW, General Motors, Honda, Hyundai, Kia, Mercedes and Stellantis. The venture issued a statement on the move, saying they are trying to “accelerate the transition to electric vehicles” and “make zero-emission driving even more attractive.”

The goal of this venture is 30,000 new charging points, and the companies say they will “leverage public and private funds” to get there. After all, the National Renewable Energy Laboratory (NREL) estimates that the country will need around 182,000 fast chargers to accommodate the massive influx of EVs hitting the roads by 2030. This venture represents a good portion of these needs.

These stations will use the Combined Charging System (CCS) standard and the North American Charging Standard (NACS). It’s worth mentioning that Tesla’s superchargers use the NACS charging type and the company recently opened up the technology to other EV manufacturers.

This new joint program will formally begin operations sometime this year, assuming it clears regulatory approval conditions, and it plans on opening up its first stations next summer. Each site will boast multiple chargers and plenty of amenities, like canopies, restaurants, restrooms and integrated brick-and-mortar retail stores.

EV sales are expected to contribute to more than 50 percent of total automobile sales by 2030, so the more charging stations available, the better. To that end, some of the companies involved in this venture are also striking out on their own to build more charging stations. GM, for instance, promises to build 40,000 charging stations at car dealerships throughout the US and Canada.

NASA and DARPA have chosen aerospace and defense company Lockheed Martin to develop a spacecraft with a nuclear thermal rocket engine. Announced in January, the initiative — in which BWX Technologies will provide the reactor and fuel — is dubbed the Demonstration Rocket for Agile Cislunar Operations (DRACO). The agencies aim to showcase the tech no later than 2027 with an eye toward future Mars missions.

Nuclear thermal propulsion (NTP) has several advantages over chemically propelled rockets. First, it’s two to five times more efficient, allowing ships to travel faster and farther with greater agility. In addition, its reduced propellant needs leave more room on the spaceship for storing scientific equipment and other essentials. It also provides more options for abort scenarios, as the nuclear engines make it easier to alter the ship’s trajectory for a quicker-than-expected return trip. These factors combine to make NTP (perhaps) the ideal Mars travel method.

“These more powerful and efficient nuclear thermal propulsion systems can provide faster transit times between destinations,” said Kirk Shireman, VP of Lunar Exploration Campaigns for Lockheed Martin. “Reducing transit time is vital for human missions to Mars to limit a crew’s exposure to radiation.”

The NTP system will use a nuclear reactor to heat hydrogen propellant rapidly to extremely high temperatures. That gas is funneled through the engine’s nozzle, creating the ship’s thrust. “This nuclear thermal propulsion system is designed to be extremely safe and reliable, using High Assay Low Enriched Uranium (HALEU) fuel to rapidly heat a super-cold gas, such as liquid hydrogen,” BWX said today. “As the gas is heated, it expands quickly and creates thrust to move the spacecraft more efficiently than typical chemical combustion engines.”

To help quell concerns about radioactive leaks in the Earth’s atmosphere, NASA and DARPA plan not to power up the reactor until the ship has reached a “nuclear safe orbit,” where any tragedies would occur outside the zone where it would affect Earth. The agencies aim for a nuclear spacecraft demonstration by 2027, launched from a conventional rocket until it reaches “an appropriate location above low earth orbit.”

Nuclear reactors will also likely play a key role in powering future Martian habitats, with NASA testing small and portable versions of the tech as far back as 2018.

Before NTP propels the first humans to Mars, it could find use on much shorter flights, as nuclear-powered spacecraft could also make transporting material to the Moon more efficient. “A safe, reusable nuclear tug spacecraft would revolutionize cislunar operations,” said Shireman. “With more speed, agility and maneuverability, nuclear thermal propulsion also has many national security applications for cislunar space.”

The Overture Maps Foundation, a group founded by Amazon, Meta, Microsoft and TomTom, has released an initial open dataset that will help developers build mapping apps and other location-based tools. The "alpha" set includes worldwide info for over 59 million places, 780 million unique buildings, road data from OpenStreetMap and borders.

The map layers are packaged in a recently-launched Overture map format that's meant to be standardized and interoperable between platforms. The group is mainly sharing the data at this stage to get public feedback, rather than to support complete products.

The foundation was formed in December last year by a range of companies that include geospatial and mapping firms in addition to tech giants. While open map data isn't a new concept, Overture believes the collective effort is necessary to deliver accurate, up-to-date info that's no longer practical for any one organization to provide. Ideally, a newcomer won't have to worry about supplying outdated or incomplete directions.

Overture is quick to warn that there's still a lot of work left before its material is truly ready. Upcoming releases will include more open data, greater interoperability and the use of a stable ID system that will help map builders consistently add content. You might not see apps relying much (if at all) on the alpha dataset, but it serves as a starting point that gives app creators an idea of what's possible.

Google has historically dominated the mobile navigation app market, with Google Maps and Waze together claiming a clear majority of use in recent years. Apple Maps, meanwhile, tends to get nearly all the remaining share. There's not much room for challengers, and they normally need massive resources just to be competitive. Overture's open data could make it much easier to produce viable alternatives, even if they're unlikely to unseat Apple or Google any time soon.

Samsung didn't only have new phones to show off at its Unpacked event. The company took the opportunity to reveal the Galaxy Watch 6 too. The latest wearable starts at $300, but Amazon is sweetening the deal. If you lock in a pre-order there, you'll get a $50 Amazon gift card. Note that the offer only applies to the Bluetooth models, and not the LTE or Watch 6 Classic variants. You'll get a free fabric watch band as well. The Watch 6 will be available starting on August 11th.

The Bluetooth model does not, unfortunately, feature the return of the rotating bezel (you'll need to plump for the Galaxy Watch 6 Classic for that), but there are still some other interesting updates. During our hands-on time with it, we found that a new one-click mechanism makes it much easier to swap between certain bands.

The standard Watch 6 is available in sizes of 40mm and 44mm. The screen is much sharper and brighter this time around. It has a maximum brightness of 2,000 nits, so you shouldn't have much trouble seeing the display on a sunny day. Samsung has also upgraded the processor and added a larger battery. The company claims you'll get up to eight hours of use after eight minutes of fast charging. 

The sleep-tracking and coaching features have seemingly been upgraded, while there's a new Personalized Heart Rate Zone feature that aims to help you attain the fitness results you're looking for. Meanwhile, Samsung Wallet has replaced Samsung Pay to make the device compatible with digital IDs, boarding passes and event tickets.

Samsung has only just unveiled the Galaxy Z Fold 5 and the Galaxy Z Flip 5, but there are already deals to be had if you lock in a pre-order on Amazon. Those who pre-order the Galaxy Z Fold 5 will get a $200 Amazon gift card as well as a free storage upgrade from 256GB to 512GB. That should somewhat make up for the foldable's high base price of $1,800.

We've had some hands-on time with the Z Fold 5. There's a new hinge that all but eliminates the gap between the two halves of the screen and it reduces the device's overall thickness to 13.5mm. The Flex Hinge still has IPX8 water resistance, according to Samsung.

The Galaxy Z Fold 5 runs on a Qualcomm Snapdragon 8 Gen 2 Mobile Platform chipset and it has 12GB of RAM. The 6.2-inch OLED cover screen and main 7.6-inch display both have 120Hz refresh rates. The camera array includes a 50MP main lens, a 12MP ultra-wide and a 10MP telephoto with 3x optical zoom.

So far, we feel that the Z Fold 5 has improved multitasking, but rivals such as Google and Oppo are catching up to Samsung on the foldables front. The high price doesn't help, but at least the Amazon pre-order deal takes the sting out of that a bit. The Z Fold 5 will ship on August 11th.

Meanwhile, you'll get a $150 Amazon gift card when you pre-order the Samsung Galaxy Z Flip 5. A free storage upgrade to 512GB can be all yours too. The Z Flip 5 starts at $1,000 and it will also be broadly available on August 11th.

Samsung's latest clamshell foldable has a 3.4-inch external screen, which is nearly four times the size of the one on the previous model. It also boasts a Flex Hinge to minimize the crease between the two halves of the 6.7-inch, 120Hz AMOLED main screen.

In a slight twist, the highlight of the foldable phones this year was the "entry" clamshell device, the Galaxy Z Flip 5. The new model has a much larger 3.4-inch external display than its predecessor, letting you reply to messages, use Wallet and otherwise handle tasks that previously required opening the phone. A new hinge design also eliminates the gap when the handset is closed. You can also expect a speedier custom Snapdragon 8 Gen 2 chip and double the storage. It starts at $999, and is available for pre-order through Samsung and Amazon ahead of its August 11th release. 

The Galaxy Z Fold 5, meanwhile, is an iterative (if still welcome) update. The book-style foldable delivers a thinner, gapless design with a brighter primary display, the Snapdragon 8 Gen 2 and improved multitasking abilities. It ships August 11th starting at $1,799, and you can pre-order it now through Samsung and Amazon.

The biggest update at summer Unpacked was arguably for Samsung's smallest computing device. The company unveiled a Galaxy Watch 6 family that makes some much-requested improvements to the Wear OS timepieces. Most notably, the rotating bezel is back — buy a Galaxy Watch 6 Classic and you can scroll through apps and widgets with a tactile feel. Both watches offer larger, brighter displays, upgraded processors, larger batteries and a "one-click" strap swapping system.

The Galaxy Watch 6 line arrives August 11th. You can pre-order through Samsung and Amazon starting at $300 for the base model and $400 for the Classic.

Samsung catered to fans of high-end Android tablets at unpacked by introducing the Galaxy Tab S9 range. While the design hasn't changed much (mainly slimmer bezels), it's still a significant upgrade with dynamic refresh rate AMOLED screens, the custom Snapdragon 8 Gen 2 chip, more powerful speakers and even IP68 water and dust resistance for both the tablet and included S Pen.

The series goes on sale August 11th, with pre-orders open at Samsung and Amazon. The 11-inch Galaxy Tab S9 starts at $800, while the 12.4-inch Tab S9+ begins at $1,000. The enormous 14.6-inch Tab S9 Ultra costs at least $1,200.

Seven years after Bumble launched Bumble BFF, the company is finally giving users their own app for making friends. Bumble has announced the release of Bumble For Friends, an app dedicated solely to finding friends in your area. The company started testing the app earlier this year in the United Kingdom and select regions of Asia, Mashable reported. 

Bumble For Friends will function almost exactly like Bumble BFF (which makes up 15 percent of Bumble's monthly active users, a Bumble spokesperson told TechCrunch). However, there will be no need to download a dating app — something coupled-up users will likely be happy about. Like a dating app, though, you create a profile with a mix of photos, information about yourself and responses to prompts. It can include things like if you drink, your political affiliation, your relationship status and why you're looking to make friends. Your Bumble For Friends profile will also have space to share some of your interests, like dogs or dancing — one of the things Bumble uses to help match you with potential friends.

There is one new feature on Bumble For Friends: the option to create a group chat. Basically, if you think any of your matches would also get along, you can add two or more of them to a group chat. To use this option, go into the conversations tab and pick a Bumble-suggested activity or add your own. You can also just give the group chat a name (which you can edit later on) if you don't want to pick what to do. From there, you can invite matches and get talking. Invitees will receive a notification about the chat showing them your chosen title or the potential activity.

Bumble For Friends is free to download on Apple's App Store or the Google Play Store. You can create a new account or log into your existing one and have your profile and matches transferred over. At that point, your Bumble BFF account will disappear from the original app, but you can still use Date or Bizz modes. Bumble doesn't seem to be forcing anyone to switch to the new app, so you can still keep all your accounts in one place if you prefer.

Robotics engineer Ken Pillonel, known for creating a makeshift USB-C iPhone and AirPods, has revealed his next project. The modding wunderkind has deconstructed Apple’s AirPods Pro case and built a custom repairable version. Pillonel is sharing the design for free, allowing enterprising self-repair enthusiasts with a knack for engineering to make their own.

Pillonel has already tackled the AirPods Pro with a custom replaceable printed circuit board (PCB). However, his new project attempts to dissect the earbuds’ entire case, offering a complete blueprint for others to do the same — with 3D-printed sections and a few (cheap) afterparty parts. “Most gadgets are designed without repairability in mind, unlike the durable technology of the past that seemed built to last,” Pillonel wrote, noting that iFixit gave the second-gen AirPods Pro a dismal zero repairability score. “It is troubling to see design choices like non-replaceable batteries, glued-in components, and a lack of transparency in public information leading to the rise of ‘fast electronics.’”

In response, the engineer took on this latest project “to demonstrate how one of the most popular gadgets today — Apple’s AirPods Pro — could have been easily made repairable with minimal effort.” His stated goal is to inspire consumers and multi-billion-dollar corporations (ahem, Apple) to treat technology less like a locked-down disposable commodity and more like something one can tinker with, learn from and — with the right skills — repair themselves. Of course, a central component is using screws and nuts instead of adhesives to create a makeshift case you can crack open and fix down the road.

Ken Pillonel / Exploring the Simulation

Pillonel says this was one of his most challenging custom projects yet, as he had to create precise scans of the case’s every component. As he explains in the video below from his YouTube channel, some of the case’s parts proved especially difficult with complex curves that a simple caliper and basic 2D scans couldn’t quite nail down. He even detailed his quest for finding the right spring-loaded contact pins to charge the buds and an affordable 3D scanner to capture some of the more oddly shaped parts. I recommend a quick watch to anyone curious about sustainability and the nuts and bolts behind iconic consumer tech gadgets. (Remember that such tinkering will void your warranty, and you should probably only give it a shot if you’re experienced with electronics repairs.)

“I am thrilled to make these repairable designs available to the public at no cost, encouraging individuals and manufacturers alike to prioritize repairability in their product development,” Pillonel wrote today. “Together, we can work towards a circular economy that not only minimizes electronic waste but also fosters a culture of conscious consumption and responsible tech innovation.” You can peruse Pillonel’s designs and storefront for replacement parts on his website.

It's no secret that AI development brings a lot of security risks. While governing bodies are working to put forth regulations, for now, it's mostly up to the companies themselves to take precautions. The latest show of self-supervision comes with Anthropic, Google, Microsoft and Open AI's joint creation of the Frontier Model Forum, an industry-led body concentrating on safe, careful AI development. It considers frontier models to be any "large-scale machine-learning models" that go beyond current capabilities and have a vast range of abilities.

The Forum plans to establish an advisory committee, charter and funding. It has laid out for core pillars it intends to focus on furthering AI safety research, determining best practices, working closely with policymakers, academics, civil society and companies, and encouraging efforts to build AI that "can help meet society's greatest challenges."

Members will reportedly work on the first three objectives over the next year. Speaking of membership, the announcement outlines the necessary qualifications to join, such as producing frontier models and showing a clear commitment to making them safe. "It is vital that AI companies–especially those working on the most powerful models–align on common ground and advance thoughtful and adaptable safety practices to ensure powerful AI tools have the broadest benefit possible," Anna Makanju, OpenAI's vice president of global affairs, said in a statement. "This is urgent work and this forum is well-positioned to act quickly to advance the state of AI safety."

The creation of the Forum follows a recent safety agreement between the White House and top AI companies, including those responsible for this new venture. Safety measures committed to included tests for bad behavior by external experts and putting a watermark on content AI created. 

Amazon has teamed up with Boost Infinite, a wireless carrier owned by Dish Wireless, and has launched a storefront to make the latter's SIM kits more accessible. While Amazon sells SIM cards from a variety of providers, this is a genuine tie-up that automatically pre-qualifies Prime members for the carrier's $25-per-month postpaid wireless plan. Subscribers can purchase Boost Infinite's Unlimited $25 SIM kit from the Amazon store with a 20 percent discount. And if they do, they're also getting a $25 bill credit that will go towards their first month of service, provided that they've activated their SIM within 30 days of receiving it. 

Dish first introduced Boost Infinite in mid-2022 with a plan that offers "unlimited data, talk and text." The plan also provides users with 5G internet, which uses AT&T's, T-Mobile's and Dish's own network, though it will get throttled after the first 30GB of the month. Subscribers can add up to five lines per account, as well. Boost Infinite promises a wireless service with no surprise, or even planned, price hikes. It says members can expect to pay $25 a month for as long as they're active. 

Customers who purchase a SIM kit from Amazon don't have to walk into a store to activate their account. They simply need to complete their registration via the carrier's app, after which it will pair them up with a customer support rep — a "real person," the company emphasizes — to help them with setup and activation. To note, new subscribers can bring in their (unlocked) phones or get a new one from Boost Infinite, and they can keep or change their number. Boost Infinite's network is compatible with both unlocked iPhones and Android devices, and it also comes with eSIM support for Apple's mobile phones. 

Steve Downer, Vice President of Consumer Electronics at Amazon, said:

"Amazon has always been about providing convenience, value, and selection to customers. Part of that is making it easier for customers to access wireless plans that are compatible with a variety of devices and can be set up from home. The Boost Infinite Unlimited SIM kit gives Prime members an exclusive deal to access affordable postpaid wireless service on one of the top networks in the U.S. at a great value."
