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
Norwegian Man Cured of HIV by His Brother’s Stem Cells
Fewer than 10 people worldwide have eradicated the virus with stem cells. But this case was special—no one knew his brother’s cells carried a protective mutation until transplant day. When the 63-year-old man received a bone marrow transplant from his brother, he got a two-for-one deal. The therapy was meant to tame a life-threatening blood disorder. But it also wiped out all signs of HIV, which he had been battling for 14 years.Called the Oslo patient, he joins a small group of people wit
Quantum ‘Jamming’ Explores the Truly Fundamental Principles of Nature
For the past few decades, researchers have understood that quantum computers should eventually be able to crack the widely used codes that secure much of the digital world. To protect against this fate, they’ve spent years developing new codes that appear to be safe from future safecrackers armed with quantum computers. At the same time, they’ve also devised ingenious ways to use the rules of…Source
Quantum-informed AI improves long-term turbulence forecasts while using far less memory
An AI model informed by calculations from a quantum computer can better predict the behavior of a complex physical system over the long term than current best models that use only conventional computers, according to a new study led by UCL (University College London) researchers. The findings, published in the journal Science Advances, could improve models predicting how liquids and gases move and interact (fluid dynamics), used in areas ranging from climate science to transport, medicine and en
This chain of atoms can detect electric fields with stunning precision
A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of relying on traditional vapor-cell methods, researchers developed a system using chains of highly sensitive Rydberg atoms that respond collectively to electric fields. As the field shifts, it subtly changes how these atoms interact, allowing both the strength and direction of the field to be decoded with
