MIT engineers develop a magnetic transistor for more energy-efficient electronics

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Science news this week: Time emerges inside a mini-universe, scientists thicken Arctic ice, and one of the oldest graves of a free Black person in the US found

This week's science news was filled with big discoveries from the world of the small, led by a physicist's creation of a mini-universe, which was designed so we can watch time emerge from within an isolated quantum system.The experiment was performed using a Bose-Einstein condensate — a strange state of matter that consists of thousands of atoms blended into a single quantum object at near absolute zero (minus 273.15 degrees Celsius, or minus 459.67 degrees Fahrenheit

Does fast charging damage your battery more than regular charging?

Fast charging seems to be almost everywhere. Many smartphones can go from nearly empty to more than 50% charged in about half an hour, while some electric vehicles can add hundreds of miles of range during a quick charging stop. But batteries aren't perfect; their capacity degrades over time. Given that fast charging delivers more power in a shorter amount of time, does fast charging damage batteries? Scientists say the answer is yes, but it's more complicated than yo

This electric field trick boosted heat flow by nearly 300%

Researchers discovered that electricity can dramatically reshape how heat flows through certain ceramic materials, increasing heat conduction by almost threefold in a preferred direction. The unexpected result could lead to much more efficient cooling technologies and energy-saving devices.

Show HN: Cactus v2 – On-device AI with cloud fallback

Hi HN, Roman and Henry here from Cactus (https://github.com/cactus-compute/cactus).We just shipped the biggest upgrade to our on-device inference platform:- Built-in model confidence-based routing to hand off inference runs to the cloud - Converter for any PyTorch model - Lossless 4-bit quantization (evals on our GitHub README) - GPU acceleration on compatible devices (starting with Apple Metal) - Minimal RAM footprint - Runs on any Arm device: iOS, Android, Mac, DGX Spark, R

Physicists finally build a quantum material predicted more than a decade ago

Researchers have achieved a major milestone by creating a long-sought two-dimensional quantum material and confirming its unusual conducting edge states. The ability to control these states through strain could make the material a promising platform for future room-temperature quantum electronics.

Tiny bubbles could revolutionize inkjet printing

Ultra-fine bubbles may offer a cleaner way to perfect inkjet printing for next-generation electronics. By simply changing the number of bubbles in each droplet, researchers were able to dramatically reshape the final printed pattern without leaving behind unwanted chemical residues.

Europe just unveiled a new rival to SpaceX’s Starship

A detailed independent study found that SpaceX's Starship is every bit as revolutionary as expected, while revealing both its impressive capabilities and its biggest remaining hurdles. It also introduces an ambitious European rocket concept that could offer a very different route to affordable super heavy launches.

NASA is creating a fifth state of matter on the ISS, thanks to an upgrade to a mini-fridge-sized quantum lab

A new upgrade to the International Space Station's (ISS) quantum laboratory is enabling NASA to probe the behavior of atoms further than ever before, the space agency has announced.Combining the ISS's newly upgraded "Cold Atom Laboratory" with the near zero-gravity of low Earth orbit, scientists are attempting to understand the properties of so-called "ultracold" atoms in an environment impossible to replicate on Earth. The aim of the mission is to study how clouds of

Announcing BQP Partners: my and my brother’s new angel-investing venture

As I’ve written before, these past couple years I’ve often felt like the last remaining person in either quantum computing or AI who lacked a stake in some startup company whose valuation is right now shooting into interstellar space. My academic colleagues, including the ones who seemed the most singleminded about quantum oracle separations and other gloriously useless pursuits? One by one, like in a zombie movie, I learn that they too have now launched startups, and invariably ra

CAR T Revolutionized How We Treat Blood Cancers. Now It’s Closing In on Solid Tumors.

Separate teams discovered the same target in solid cancers, enabling a powerful two-pronged attack on both tumors and the cells shielding them. Cancer researchers just found a new way to take on tumors.CAR T cell therapy revolutionized blood cancer treatment by supercharging a patient’s own immune cells to hunt down cancers. But the approach has struggled in solid cancers. These are some of our top killers—breast, lung, prostate. Roughly two million Americans are expected to be diagnosed with ca
