Asteroid samples fetched by NASA hold not only the pristine building blocks for life but also the salty remains of an ancient water world, scientists reported Wednesday.

The findings provide the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start.

“That’s the kind of environment that could have been essential to the steps that lead from elements to life,” said the Smithsonian Institution’s Tim McCoy, one of the lead study authors.

Nvidia CEO Jensen Huang has a vision for the future — and some advice for the generations that will have to navigate it.

In a recently released interview on Cleo Abram’s “Huge Conversations,” recorded on January 7, Huang said he expected massive leaps in what he called “human robotics” within the next half decade and a broadening in the applications of artificial intelligence.

Multiple companies across both the US and China, among other countries, are working to launch and scale the production of humanoid robots for use in manufacturing and consumer applications.

The field of quantum computing is advancing relentlessly: equipped with a performance that far exceeds that of our conventional PCs, the high-tech computers of the future will solve highly complex problems that have so far defeated even the largest supercomputers. And indeed, Chinese researchers have now made another breakthrough in the digital world of qubits – and with the Zuchongzhi 3.0, they have presented a quantum computer that even rivals Google’s Willow! But what can the new high-tech computer do? How does a quantum computer work anyway? And above all, how will the high-performance computers change our everyday lives?

At UC Berkeley, researchers in Sergey Levine’s Robotic AI and Learning Lab eyed a table where a tower of 39 Jenga blocks stood perfectly stacked. Then a white-and-black robot, its single limb doubled over like a hunched-over giraffe, zoomed toward the tower, brandishing a black leather whip.

Through what might have seemed to a casual viewer like a miracle of physics, the whip struck in precisely the right spot to send a single block flying out from the stack while the rest of the tower remained structurally sound.

This task, known as “Jenga whipping,” is a hobby pursued by people with the dexterity and reflexes to pull it off. Now, it’s been mastered by robots, thanks to a novel, AI-powered training method.

Bloomberg on the Economic Singularity:

“If AI is about to get much cheaper, the path to an answer on its economic impact is going to get shorter. For workers nervously wondering if large language models will make their skills redundant, a lot is riding on which camp is right.”

For investors in artificial intelligence, the last week delivered a painful shock. The sudden appearance of DeepSeek — a Chinese AI firm boasting a world-class model developed at bargain-basement costs — triggered a massive selloff in Nvidia and other US tech champions.

What matters for the economy, though, is not the ups and downs of stock prices for the Magnificent Seven, but whether AI drives gains in productivity, and how those gains are divided up. For all the excitement, and the trillion-dollar valuations for AI firms, evidence of a boost to productivity remains thin on the ground.

The creation of energy from nuclear fusion has been a goal for decades. And technology advances at companies like General Atomics in San Diego are bringing us closer to it. KPBS sci-tech reporter Thomas Fudge tells us about this quest to put the “sun in a bottle,” and use it to provide what would be abundant power.

Can you make something invisible? Neil deGrasse Tyson and comedian Negin Farsad discover the science behind invisibility with professor of physics and optical science, Greg Gbur. What would real-life invisibility look like?

Can you be invisible in other parts of the magnetic spectrum? We discuss transparency versus invisibility and how metamaterials help us interact with different wavelengths. What does light have to do in order to make something invisible? We break down invisibility cloaks and other invisibility devices from fiction.

Could you make yourself invisible to all parts of the electromagnetic spectrum? We explore the main challenges in achieving invisibility and the difference between passive and active invisibility. How useful of a power would it be?

We discuss the interaction between waves and matter. What makes some waves reflect off matter and others pass through? Learn about x rays and how they work, plus, an at-home invisibility trick using prisms. Finally, could you make someone invisible to time?
