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

Strain flips Hall signal in altermagnetic manganese telluride, suggesting a path to practical spintronics

Time-reversal symmetry is an exotic behavior found in systems whose internal physics looks different when running forward versus backward in time. For some time, physicists have searched for this behavior in systems with almost no overall magnetization. Such phases are highly prized for spintronics, where information is carried using the quantum spins of electrons.

Oracle (ORCL) Adds Quantum Computing To Its Cloud, So What’s The Catch?

Oracle (NYSE:ORCL) just gave its cloud story a new frontier. On August 12, the company announced a multi-year partnership with Quantinuum to bring quantum computing to Oracle Cloud Infrastructure, adding one more growth narrative to a stock that has already been on a wild ride. The deal is the clearest sign yet that Oracle wants […]

Ask HN: Ive quit six systems for tracking my illness. What works?

Hey everyone, I am a 20 year old college student who was recently diagnosed with seronegative spondyloarthropathy. Over the last 3 years, Ive tried apps, paper journal, Google Sheets, and notes to track/catalogue my journey. I always ended up quitting within 2-4 weeks and not keeping accurate track.Is this a common experience or do I just have to be better at tracking? Is there a unique/non habit-building way to track/catalogue/recall?Im building something for this (part of t

Physicists discover a hidden gluon structure inside protons that could rewrite textbooks

Physicists may have uncovered a hidden feature inside protons that helps preserve one of matter’s most fundamental properties. RHIC collision data suggest baryon number is carried not simply by three quarks, but by a Y-shaped junction of the gluons connecting them. The finding challenges a decades-old textbook picture and could deepen our understanding of why protons—and ultimately matter itself—remain stable.

A black hole shredded a “super sun” — but something strange may have survived

Astronomers have witnessed a black hole violently shredding a massive star, creating one of the most energetic stellar explosions ever observed. The event, nicknamed “the Whippet,” briefly released about 400 billion times the Sun’s energy and sent a shock wave racing outward at one-fifth the speed of light. Months later, scientists spotted unexpectedly fast-moving helium, suggesting that some structure may have survived the destruction.

First-in-history: Chinese scientists achieve quantum entanglement over 420km distance

Chinese scientists achieved quantum entanglement of cold atoms over 420km, surpassing previous records and enabling advancements toward intercity quantum communication networks.

Ultrafast core-level spectroscopy reveals elusive precursors of exciton condensation in quantum materials

Many fascinating phases in quantum materials emerge when electrons, atoms and other microscopic components begin to act collectively. But these phases do not necessarily appear out of nowhere when a material crosses a transition temperature. Before long-range order develops, microscopic fluctuations can already be present.

Wayland, Pipewire, Open Source Slowly Closing?

I am kinda depressed over these factors. I have used linux since 2015 and really never ran into problems until the past five years.I am a composer with a prolithic output; and had a steady workflow for most of the years until musegroup bought out audacity and musescore. (which i have been able to get musescore 2 in a few distros; as i prefer this over any of the post-musegroup alterations.)the same goes for audacity; prior to their changes it worked... everything flowed beautifully; and boom so

Alternative to Internet Archive

Now; i use the archive to archive my prolithic output of music. (i have over 300 albums.) The music is of my own creation.Since the DDoS attack of 2024; Archive has been a hit or miss on the uploading factors. And many of my releases have specific dates for release. With the uncertainty of the uploads happening it causes me to break focus on working with music and watch the upload to make sure there isn't a 503 happening each file. (which sometimes happens frequently.)I am in search of a si

Artificial IntelligenceThese Startups Are Chasing the Next Big Thing in LLMsWill Douglas Heaven | MIT Technology Review ($)“Transformers are starting to show their age. Many of the recent advances in LLMs, such as the development of so-called reasoning models and their ability to handle large amounts of input at once, are not neat extensions of that core technology but workarounds that patch over some of its fundamental flaws. A growing number of scientists and engineers are now asking wha
