For the first time ever, scientists have reanimated a cryogenically frozen mammal brain

Researchers behind proof of a technique that successfully froze a mammalian brain have won an award for their efforts, possibly leading to advancements in the emerging field of brain preservation.

21st Century Medicine is behind the work, and already offers several services to clients interested in the idea of cryogenic preservation. In this case, 21CM was able to almost completely preserve the structure of a rabbit brain following cryogenic freezing and then rewarming of the organ.

The Brain Preservation Foundation — the group behind the award — says it is the first demonstration “of near­ perfect, long­-term structural preservation of an intact mammalian brain.” The work also suggests that actual synapses within the brain could be preserved, which could eventually be retrieved or uploaded to a computer after the passing of the donor.

Cryogenics, and its possible benefits, are still more science fiction than fact — but we’ve made some notable advancements in the past few years. While groups like the Alcor Life Extension Foundation have offered cryonics as a way to preserve oneself in hopes of reanimation in some future time, none have figured out a way to actually do it.

Current cryopreservation methods tend to “dry out” the brain, which in turn damages pathways, making possibilities for recovery less successful. 21CM’s method is a bit different, and uses a mixture of cryonic and chemical preservation to prevent drying out, but not using enough chemicals to cause other types of decay.

“Every neuron and synapse looks beautifully preserved across the entire brain,” BPF president Dr. Kenneth Hayworth said in an announcement posted to the organization’s website. “Simply amazing given that I held in my hand this very same brain when it was vitrified glassy solid.”

While so far 21CM has only proven that its technique works on smaller mammal brains, the company does plan to show its techniques work on larger mammal brains too. The BPF will hold a similar contest for large mammals, and the company says it already has proof of concept that it is just as effective.

No word on whether the BPF plans to hold a similar contest to show these efforts work on human brains, but one can’t help but assume such a contest isn’t that far behind.

Subaru’s electric comeback starts now: Trailseeker EV to debut in NYC
subaru trailseeker ev debut 2026 4  thumb

Subaru is finally accelerating into the EV fast lane. The automaker is officially teasing the 2026 Trailseeker, an all-new electric SUV set to debut at the New York International Auto Show next week. While details are still scarce, the Trailseeker marks Subaru’s long-awaited second entry into the EV space, joining the Solterra — and the expectations couldn't be higher.
The teaser image offers only a glimpse of the Trailseeker’s rear badge and taillight, but the name alone suggests rugged ambitions. It's a clear nod to Subaru’s outdoorsy heritage. But in the EV space, the outdoors belongs to brands like Rivian, whose upcoming R2 compact SUV is already turning heads. The Trailseeker is Subaru’s chance to reassert its identity in an electric age.
Currently, Subaru’s only EV is the Solterra, a joint venture with Toyota that shares a platform with the bZ4X. While the Solterra nails some Subaru essentials — all-wheel drive, spaciousness, and off-road capability — it falls short on key EV metrics. Reviewers have pointed to its modest 225-mile range, slow 100kW charging, and unremarkable acceleration, especially compared to rivals like the Hyundai Ioniq 5  or Ford Mustang Mach-E.
The hope is that Subaru has learned from these criticisms and is poised to deliver a more competitive product. The Trailseeker could either be a variation of a newer Toyota EV (possibly the next-gen C-HR+), or something entirely new under the shared platform strategy. Subaru previously announced that its next three EVs would be co-developed with Toyota, before launching four in-house EVs by 2028.
Given how long Subaru has waited to expand its EV offerings, the Trailseeker has to deliver. It's not just about adding a second electric model — it's about keeping pace with a market rapidly leaving legacy automakers behind. If the Trailseeker can improve on the Solterra's shortcomings and channel that classic Subaru ruggedness into a truly modern EV, it might just be the spark the brand needs.

I tested the world-understanding avatar of Gemini Live. It was shocking
Scanning a sticker using Gemini Live with camera and screen sharing.

It’s somewhat unnerving to hear an AI talking in an eerily friendly tone and telling me to clean up the clutter on my workstation. I am somewhat proud of it, but I guess it’s time to stack the haphazardly scattered gadgets and tidy up the wire mess. 

My sister would agree, too. But jumping into action after an AI “sees” my table, recognizes the mess, and doles out homemaker advice is the bigger picture. Google’s Gemini AI chatbot can now do that. And a lot more.

Amazon is aiming to take on SpaceX’s Starlink internet service using thousands of its own Project Kuiper satellites in low-Earth orbit.

The first Project Kuiper satellites were suppsoed to launch aboard a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral in Florida on April 9, but rough weather conditions forced the mission team to scrub the planned liftoff.
