First high-speed full-body 3D scanner ready for clinical tests on humans
Scientists from the University of California Davis in partnership with Shanghai-based United Imaging Healthcare (UIH) have developed a scanner capable of producing 3D images of the entire human body at once. The first images were released on November 17, 2018 and, as promised, they provide a level of detail not available in any other device in the world. Named EXPLORER, the machine has been 13 years in the making and was funded by grants from the National Cancer Institute and the National Institutes of Health. The initial concept for EXPLORER was devised by UC Davis scientists Simon Cherry and Ramsey Badawi, and another 40+ scientists make up the team involved in its development from multiple universities.
Using a type of sectional imaging called PET (positron emission tomography), EXPLORER can produce a whole body scan in as little as 20 to 30 seconds, which is about 40 times faster than current scan capabilities. The machine is also unique in its overall sensitivity, specifically 40 times higher than existing commercial systems. This enhanced capability means much higher resolution images, significantly lower radiation dosage requirements, quicker scans, and the ability to track radiotracers for a longer period of time. The fast scanning ability could also avoid the need for anesthesia in young children.
PET is a safe medical imaging technique that either maps the location or tracks the movement of dye placed into the body containing miniscule amounts radioactive elements (“radiotracers”). Certain organs and tissue absorb the dye, providing information for doctors to analyze and assess their functionality. Specifically, a PET scan shows where the dye collects. Through this method, blood flow and oxygen activity can be measured, along with many other functions, and it is commonly used to detect cancer, heart problems, and issues with the central nervous system.
Given the improvements provided by EXPLORER, the team’s scientists and UIH, the company that built it, hope their machine will improve things in the clinical environment such as diagnosing and tracking diseases, providing detailed information about drug therapies, and obtaining better data on cancer that has metastasized. They are further working together to install the EXPLORER system in Sacramento and plan to begin imaging patients in June of 2019. The goal overall is to make EXPLORER available to the international clinical research community.

Tesla begins Grok AI chatbot rollout to Australia and New Zealand fleet
The update follows earlier deployments in the United States and Europe.
Tesla has rolled out its Grok AI assistant to Australia and New Zealand, embedding the conversational chatbot directly into compatible vehicles via an over-the-air update.
The system, developed by Elon Musk’s xAI, is now live on select models, giving drivers access to a voice-based assistant that goes well beyond traditional command-driven controls.
The update follows earlier deployments in the United States and Europe.
Tesla Australia confirmed Grok is available on Model S, Model 3, Model X and Model Y vehicles equipped with an AMD processor and running software version 2025.26 or later.
“Grok is coming to Teslas in Australia and New Zealand. It can answer almost any question using real-time information & also add/edit navigation destinations to become your personal guide. Phased rollout has now begun to eligible vehicles,” Tesla Australia and New Zealand wrote in a post on its official X account.
Drivers can activate Grok using the steering wheel controls once the update is installed. Access requires either a Premium Connectivity subscription or a stable Wi-Fi connection.
Unlike conventional in-car voice assistants that rely on fixed prompts, Grok is designed to respond conversationally. It can adjust navigation mid-trip, locate nearby points of interest, explain dashboard warnings, provide driving guidance and reference the owner’s manual.
Tesla noted that interactions with Grok are processed by xAI and remain anonymous to Tesla, adding that conversations are not linked to a specific driver or vehicle.
Grok has attracted attention overseas for offering multiple interaction modes. In the U.S., users can select personalities such as Assistant, Language Tutor, Therapist, Storyteller and Meditation. Additional optional modes for adult users include settings labeled Unhinged, Motivation, Argumentative, Romantic and even Sexy.
Viral clips shared online have shown Grok adopting sarcastic or playful tones that differ from more neutral digital assistants, with the AI assistant typically catching drivers off-guard with its sharp personality and wit.

Ford is charging for a basic EV feature on the Mustang Mach-E
When ordering a new Ford Mustang Mach-E, you’ll now be hit with an additional fee for one basic EV feature: the frunk.
Ford is charging an additional fee for a basic EV feature on its Mustang Mach-E, its most popular electric vehicle offering.
Ford has shuttered its initial Model e program, but is venturing into a more controlled and refined effort, and it is abandoning the F-150 Lightning in favor of a new pickup that is currently under design, but appears to have some favorable features.
However, ordering a new Mustang Mach-E now comes with an additional fee for one basic EV feature: the frunk.
The frunk is the front trunk, and due to the lack of a large engine in the front of an electric vehicle, OEMs are able to offer additional storage space under the hood. There’s one problem, though, and that is that companies appear to be recognizing that they can remove it for free while offering the function for a fee.

Ford is charging $495 for the frunk.
Interestingly, the frunk size varies by vehicle, but the Mustang Mach-E features a 4.7 to 4.8 cubic-foot-sized frunk, which measures approximately 9 inches deep, 26 inches wide, and 14 inches high.
When the vehicle was first released, Ford marketed the frunk as the ultimate tailgating feature, showing it off as a perfect place to store and serve cold shrimp cocktail.
Ford Mach-E frunk is perfect for chowders and chicken wings, and we’re not even joking
It appears the decision to charge for what is a simple advantage of an EV is not going over well, as even Ford loyal customers say the frunk is a “basic expectation” of an EV. Without it, it seems as if fans feel the company is nickel-and-diming its customers.
It will be pretty interesting to see the Mach-E without a frunk, and while it should not be enough to turn people away from potentially buying the vehicle, it seems the decision to add an additional charge to include one will definitely annoy some customers.

Tesla to improve one of its best features, coding shows
According to the update, Tesla will work on improving the headlights when coming into contact with highly reflective objects, including road signs, traffic signs, and street lights. Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Tesla is looking to upgrade its Matrix Headlights, a unique and high-tech feature that is available on several of its vehicles. The headlights aim to maximize visibility for Tesla drivers while being considerate of oncoming traffic.
The Matrix Headlights Tesla offers utilize dimming of individual light pixels to ensure that visibility stays high for those behind the wheel, while also being considerate of other cars by decreasing the brightness in areas where other cars are traveling.
Here’s what they look like in action:

As you can see, the Matrix headlight system intentionally dims the area where oncoming cars would be impacted by high beams. This keeps visibility at a maximum for everyone on the road, including those who could be hit with bright lights in their eyes.
There are still a handful of complaints from owners, however, but Tesla appears to be looking to resolve these with the coming updates in a Software Version that is currently labeled 2026.2.xxx. The coding was spotted by X user BERKANT:

This is a major step beyond current adaptive high beams.

Additionally, pixel-level dimming will happen in two stages, whereas it currently performs with just one, meaning on or off.
Finally, the new system will prevent the high beams from glaring back at the driver. The system is made to dim when it recognizes oncoming cars, but not necessarily objects that could produce glaring issues back at the driver.
Tesla’s revolutionary Matrix headlights are coming to the U.S.
This upgrade is software-focused, so there will not need to be any physical changes or upgrades made to Tesla vehicles that utilize the Matrix headlights currently.
