I didn't bring my son to a museum to look at screens

When I was a kid in the ’80s, one of my two favorite places on Earth was The Franklin Institute (TFI) in downtown Philadelphia. We lived a couple hours away so a visit was a rare and precious thing. I think I only visited two or three times but it left an indelible impression on me. I remember wandering in amazement through its enormous spaces getting to actually play with amazing and interesting things.

Spotify peeved after 10,000 users sold data to build AI tools

For millions of Spotify users, the "Wrapped" feature—which crunches the numbers on their annual listening habits—is a highlight of every year's end, ever since it debuted in 2015. NPR once broke down exactly why our brains find the feature so "irresistible," while Cosmopolitan last year declared that sharing Wrapped screenshots of top artists and songs had by now become "the ultimate status symbol" for tens of millions of music fans.

Looking to upgrade the audio for your phone or action camera footage? Amazon is offering $60 off the DJI Mic Mini kit. Our reviewer gave DJI's lavalier mic a 7/10 and this kit includes two mics, a receiver, and a handy charging case. That's the lowest price yet for this bundle at just $109, and a great value on this easy to use and lightweight microphone.

Inverting the Xorshift128 random number generator

CVE-2025-7783 is a very recent vulnerability affecting a lot of applications in the Node.js ecosystem including those which use axios or the deprecated request library. In all honesty, this vulnerability is really an edge case that is extremely unlikely to be exploited: it is dependent upon a number of events that are not normally present. One of those events is the attacker having access to five consecutive outputs of JavaScript Math.random( ) , which allows the attacker to predict future outpu

Creating a qubit fit for a quantum future

technologyreview.com Unknown 2025-10-29 03:00:00

A topological alternative For the team at Nokia Bell Labs, the solution lies in better qubits rather than bigger machines. Specifically, rather than information encoded in individual elementary particles, the team is focused on qubits that hold this same information in the way matter is spatially oriented—what is known as a topological qubit. This alternative approach uses electromagnetic fields to manipulate charges around a supercooled electron liquid, triggering the qubits to switch between

The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, quantum computers should be able to—in theory—surpass the computational potential of any classical supercomputer. But before quantum advantage drastically changes information technology as we know it, researchers have yet to address the many hurdles that are preventing quantum computers from entering into the mainstream.

Regeneration is a trick many animals, including lizards, starfish, and octopuses, have mastered. Axolotls, a salamander species originating in Mexico, can regrow pretty much everything from severed limbs, through eyes and parts of brain, to the spinal cord. Mammals, though, have mostly lost this ability somewhere along their evolutionary path. Regeneration persisted, in a limited number of tissues, in just a few mammalian species like rabbits or goats. “We were trying to learn how certain anima

He and others came up with several mechanical models, in which gravity was not a pull, but a push. For example, space might be filled with unseen particles that bombard the objects on all sides.
