Since 2022, Google, Meta and SoCal Edison have contracted ~1.2 GW of geothermal power from plants that haven’t been built yet, at $105–107/MWh.

AI needs firm, carbon-free power. Our new white paper looks at where geothermal goes next: https://t.co/MIL0fzsN9A

Most AI companies ask you to trust their privacy policy.

Hark strapped its founder to a polygraph instead.

Sells user data? No.
Employees can see your info? No.
Keeps it after you delete it? No.

Examiner's verdict: truthful.

The team blindsided me with a polygraph test, it was crazy. But it's important to me that Hark does this right.

Your data is yours.

[Brett Adcock @adcock_brett]

Hark launches this week. The first 100,000 sign-ups get a paid plan for free

I don't do anything without Hark anymore. The team has obsessed over every detail, and it shows. Can't wait to see how you all use it

"Okay, I have a lot to say."

Those were the first words a Michigan woman with motor neuron disease spoke through @Paradromics' Connexus BCI. @Forbes calls it a landmark year for the company and the implanted brain-computer interfaces. 🔗 https://t.co/UawYtRYdKU

Struldbrugg, Dorian Gray, Peter Pan, and Wolverine are all longevity-biology archetypes.

Only one unlocks the real trillion-dollar prize, and our reimbursement system rewards exactly the wrong one. Partner Justin Briggs (@briggsly) maps the longevity investment landscape and outlines the technology that excites us most.

[Justin Briggs @Briggsly]

$38 trillion is longevity’s most-quoted number, and the least useful.

It isn’t revenue, it isn’t annual, it isn’t addressable, and it’s not what your drug will earn.

It’s the societal value of one added healthy year.

New piece for @primemoverslab on what a year of life is actually worth. And why how you add it matters more than how big the headline is.

Most people assume a vacuum is empty.

@DrSonnyWhite, founder of Casimir, joined Partner @gavinmathis on Prime Movers to explain why that's wrong — and why it could matter for how we generate power.

[Hark @hark_labs]

Today, we’re partnering with AT&T to bring you the next generation of AI-native consumer devices.

AT&T is also investing in Hark and collaborating in areas like device certification and network connectivity.

AT&T’s infrastructure paired with Hark’s AI platform and hardware will help enable Hark to become the leader in personalized consumer intelligence.

Jensen is back in the house!!

Jensen and Nvidia have been phenomenal partners. I'm excited to be working closely together as we massively scale up this year

[Brett Adcock @adcock_brett]

Today we're introducing Hark Handoff

Handoff has been independently verified as the best internet-use model ever built, outperforming ChatGPT 5.4 & Opus 4.8

While others focus on coding, we focus on everyday life: ordering food, booking flights, shopping, & navigating the web

[Commonwealth Fusion Systems @CFS_energy]

Today, CFS announced another major advance in our fusion energy push: we raised an additional $1 billion in funding. This is the largest investment round in commercial fusion worldwide since our $1.8 billion funding round in 2021, bringing our total capital raised to $4 billion.

This investment reflects growing confidence from new partners in our technical progress, our team, and our commercialization path. It comes at a time when it’s clear the world needs a new energy option that provides safe, clean, and firm electricity.

“CFS is making what once was impossible into inevitable,” said CFS CEO and Co-founder @BobMumgaard. “In the 2030s, we will put commercial fusion on the grid. We have the science that works and the proven execution that’s consistently validated by the market. We regularly welcome investors from around the world to our headquarters in Devens, Massachusetts, where they see real and tangible progress as we ready support systems and finalize the assembly of SPARC. In unlocking commercial fusion energy, we’re on a path to make an impact at a civilizational level.”

CFS will use the funds raised to further accelerate our commercialization progress. In parallel to completing the assembly of our SPARC fusion demonstration machine, we’ll continue to develop the world’s first grid-scale fusion power plant, called ARC, at our Fall Line Fusion Power Station in Chesterfield County, Virginia.

AI's power problem is reshaping how nuclear gets built. Hyperscalers don't want a decade-long wait for a gigawatt — they want tens to a few hundred megawatts, sited fast. That demand shape is why capital is moving toward small modular and microreactors. We break down the economics in our latest white paper: https://t.co/LjRMUKcFyt

Last year, we proved what was possible.

Today, we're accelerating what comes next.

Venus Aerospace has closed a $91M Series B led by @MercuryFund, with participation from @LockheedMartin Ventures, to transform our flight-proven RDRE into deployable propulsion systems for defense and space.

The next chapter starts now.

From proven medical-device materials to a surgical approach grounded in familiar neurosurgical practices, every element of the Connexus Brain-Computer Interface (BCI) was designed to deliver high performance while prioritizing safety and reliability.

Paradromics Chief Scientific Officer Vikash Gilja explains how we engineered our solution to match standards and techniques neurosurgeons already know. This way, surgical teams have a clear, familiar path from the first procedure forward.

New @PrimeMoversLab white paper from VP of Engineering Roger Carter: "Energy Eats Intelligence: Power Generation."

What AI's energy appetite will actually cost, which technologies can supply it, where they can be built, and how soon. Essential reading for anyone building or backing the AI build-out. https://t.co/PObHTebFpD

3 years ago we only had 2 humanoid robots…Never thought I’d say this, but we’re now building so many robots that we need storage space for them

[Paradromics Inc. @paradromics]

Accessing the brain unlocks more capabilities than most companies are building for. We're starting to ask what else is possible.

Paradromics CEO and Founder @Matt_R_Angle recently joined journalist Moira Gunn at @SynBioBeta 2026 to reveal what happens when you treat neural data as a platform rather than a pathway to a single application.

The same hardware that helps someone regain the ability to communicate can be repositioned to help control a robotic arm. Place the device in areas of the brain involved in mood and cognition, and you're reading out something entirely different.

Each time you place the device in a new brain area, you open up new frontier applications.
