Run hard, breathe easy: Heated balaclava helps athletes in cold weather

Balaclavas may carry connotations of crime and concealment, but they are practical for anyone braving a frigid climate. And they just got warmer thanks to researchers from Nottingham Trent University in the United Kingdom and German knitting machine manufacturer Stoll who teamed up to develop a smart balaclava prototype that uses high-tech yarn to heat oxygen as the wearer breathes in.

“I’m personally a passionate runner and have had always bronchial issues when running in minus temperatures,” Stoll’s Head of Fashion and Technology Joerg Hartmann told Digital Trends. “This was the starting point for us to build into the mouth section a copper wire which heats up the inhaled air before entering the lungs.”

Looking something like a knitted ninja turtle’s mask your awesome grandma may make, the smart balaclava features a patch of electric-conductive yarn that rests over the nose and mouth. A cell battery pocket at the back of the headpiece provides steady power to the conductive wires, which heat the air as the wearer breathes. The headgear is accented by reflective threads and four-way stretch for a better fit. The balaclava earned the Gold Award at the 2016 Outdoor Industry Awards.

The Outdoor Industry Awards judges said, “This really is an innovation. The seamless construction is great — when we tried it on, the balaclava is really comfortable and the heating system around the mouth is a fine idea.”

As a prototype, the smart balaclava is intended to showcase the potential of the company’s sports garments while driving the technology forward. “I’m certain that the integration of conductive wires and other electronics like sensors will solve a lot of issues in an aging society,” Hartmann said.

Slate Unveils $20K Electric Truck That Transforms Into an SUV
slate 20k ev blank  roller 1 web

Slate Automotive, a new American EV startup, has just unveiled its first vehicle: a radically minimalist electric truck that can convert into a five-seat SUV. Dubbed the “Blank Slate,” the EV made its debut this week, instantly turning heads not just for its versatility but for its incredibly low price—starting under $20,000 after federal tax incentives.

Unlike Tesla and Lucid, which launched with high-priced luxury models, Slate wants to flip the model: start cheap, scale up.
At its core, the Slate Truck is a utilitarian, two-seat electric pickup designed for simplicity and affordability. But what sets it apart is its transformative potential. Thanks to a modular accessory system, the truck can be upgraded over time—including a kit that adds a rear seat, roll cage, airbags, and SUV body panels. This means buyers can start with a minimalist pickup and evolve it into a family-friendly SUV—either themselves or through Slate’s growing network of service partners.
Customization is central to Slate’s vision. Owners will be able to choose from over 100 accessories at launch, ranging from vinyl wraps and Bluetooth-ready audio systems to larger battery packs and off-road upgrades. The company encourages a DIY approach, offering tools and tutorials through “Slate University” to empower users to modify and maintain their own vehicles.
Powering the truck is a 52.7-kWh battery for up to 150 miles of range, or an optional 84.3-kWh pack targeting 240 miles. Fast-charging capabilities and Tesla’s NACS port come standard. The vehicle is rear-wheel-drive and delivers around 200 horsepower—enough for urban commuting and light-duty hauling.
What enables the low price is Slate’s stripped-down approach to manufacturing. There’s no paint shop, no stamping, and only one trim level—everything else is modular. The vehicle features steel wheels, crank windows, and a rugged plastic body designed to take a beating and still look good. It’s a rejection of the tech-saturated, high-cost vehicles dominating today’s market.
Despite the minimalist specs, Slate isn’t skimping on safety. The truck is engineered to meet top crash test ratings and comes equipped with up to eight airbags, active emergency braking, and forward collision warning.
Backing this ambitious approach is significant investor support—including Amazon founder and CEO Jeff Bezos. That backing, combined with a simplified production model, positions Slate to scale quickly once production begins in 2026.
Reservations are now open for $50 at slate.auto, with deliveries expected in late 2026. Whether Americans are ready for a stripped-down, shape-shifting EV remains to be seen, but Slate’s bet on affordability and customization could make it one of the most disruptive entries in the EV market to date.

ChatGPT’s awesome Deep Research gets a light version and goes free for all
Deep Research option for ChatGPT.

There’s a lot of AI hype floating around, and it seems every brand wants to cram it into their products. But there are a few remarkably useful tools, as well, though they are pretty expensive. ChatGPT’s Deep Research is one such feature, and it seems OpenAI is finally feeling a bit generous about it. 

The company has created a lightweight version of Deep Research that is powered by its new o4-mini language model. OpenAI says this variant is “more cost-efficient while preserving high quality.” More importantly, it is available to use for free without any subscription caveat.

Star Wars legend Ian McDiarmid gets questions about the Emperor’s sex life
Ian McDiarmid as the Emperor in Star Wars: The Rise of Skywalker.

This weekend, the Star Wars: Revenge of the Sith 20th anniversary re-release had a much stronger performance than expected with $25 million and a second-place finish behind Sinners. Revenge of the Sith was the culmination of plans by Chancellor Palpatine (Ian McDiarmid) that led to the fall of the Jedi and his own ascension to emperor. Because McDiarmid's Emperor died in his first appearance -- 1983's Return of the Jedi -- Revenge of the Sith was supposed to be his live-action swan song. However, Palpatine's return in Star Wars: Episode IX -- The Rise of Skywalker left McDiarmid being asked questions about his character's comeback, particularly about his sex life and how he could have a granddaughter.

While speaking with Variety, McDiarmid noted that fans have asked him "slightly embarrassing questions" about Palpatine including "'Does this evil monster ever have sex?'"
