Sleep-training wearable promises to give you a better night's shut-eye

There are plenty of wearable devices that claim to be able to track your sleep, but relatively few that promise to actually improve it. That’s where a new miniature wearable device called Thim — currently raising money on Kickstarter — comes into play.

Worn on any finger, Thim is designed to improve sleep for those who struggle to get good shut-eye, and it is based on the peer-reviewed research of Leon Lack, emeritus professor at Flinders University in Australia.

“World-renowned professor of sleep psychology, Leon Lack, discovered that if people experience the sensation of falling asleep again and again in quick succession, they learn to fall asleep sooner,” Ben Olsen, Thim’s founder, told Digital Trends. “That is, spending one night sleep retraining will teach your body to fall asleep sooner on the nights which follow that night of sleep retraining.”

This “sleep retraining” involves depriving a person of sleep for one night by waking them up the moment their head hits the pillow. Like any kind of training, practice makes perfect, and teaching your body to recognize falling asleep in a short space of time makes you better at sleeping steadily. In Lack’s study, participants who underwent sleep training fell asleep a half-hour sooner than those who did not, and went on to sleep for one extra hour.

Ben Olsen said that he had the opportunity to work with Lack in 2012 and was inspired by the experience. “[When] it was time to develop a new product, this was an obvious choice,” he said.

The Thim device aims to replicate Lack’s findings by figuring out when wearers fall asleep and then gently waking them three minutes later. This mild sleep interruption is, the company claims, “no more intrusive than being woken by tree leaves rustling in the breeze.” When users fall asleep again, they are once more allowed three minutes before again being awakened. This process carries on for a total of 60 minutes, before leaving users to sleep properly for the remainder of the night.

In addition to the nighttime assistance it offers, the device can also help wearers to take the perfect power nap and gain quality sleep.

“We want to help people who struggle to fall asleep,” Olsen said. “Too many people live with poor sleep, [meaning] the inability to fall asleep and stay asleep. We want to change that. We can helps millions of people with a product proven through two peer-reviewed research papers. It’s a really cool feeling.”

A Kickstarter pledge of 109 Australian dollars ($83) will secure you an early bird Thim sleep tracker, although other options are also available.

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?'"

Waymo and Toyota explore personally owned self-driving cars

Waymo and Toyota have announced they’re exploring a strategic collaboration—and one of the most exciting possibilities on the table is bringing fully-automated driving technology to personally owned vehicles.
Alphabet-owned Waymo has made its name with its robotaxi service, the only one currently operating in the U.S. Its vehicles, including Jaguars and Hyundai Ioniq 5s, have logged tens of millions of autonomous miles on the streets of San Francisco, Los Angeles, Phoenix, and Austin.
But shifting to personally owned self-driving cars is a much more complex challenge.
While safety regulations are expected to loosen under the Trump administration, the National Highway Traffic Safety Administration (NHTSA) has so far taken a cautious approach to the deployment of fully autonomous vehicles. General Motors-backed Cruise robotaxi was forced to suspend operations in 2023 following a fatal collision.
While the partnership with Toyota is still in the early stages, Waymo says it will initially study how to merge its autonomous systems with the Japanese automaker’s consumer vehicle platforms.
In a recent call with analysts, Alphabet CEO Sundar Pichai signaled that Waymo is seriously considering expanding beyond ride-hailing fleets and into personal ownership. While nothing is confirmed, the partnership with Toyota adds credibility—and manufacturing muscle—to that vision.
Toyota brings decades of safety innovation to the table, including its widely adopted Toyota Safety Sense technology. Through its software division, Woven by Toyota, the company is also pushing into next-generation vehicle platforms. With Waymo, Toyota is now also looking at how automation can evolve beyond assisted driving and into full autonomy for individual drivers.
This move also turns up the heat on Tesla, which has long promised fully self-driving vehicles for consumers. While Tesla continues to refine its Full Self-Driving (FSD) software, it remains supervised and hasn’t yet delivered on full autonomy. CEO Elon Musk is promising to launch some of its first robotaxis in Austin in June.
When it comes to self-driving cars, Waymo and Tesla are taking very different roads. Tesla aims to deliver affordability and scale with its camera, AI-based software. Waymo, by contrast, uses a more expensive technology relying on pre-mapped roads, sensors, cameras, radar and lidar (a laser-light radar), that regulators have been quicker to trust.
