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

Scientists Race to Deliver Custom Gene Therapies for Incurable Diseases in Weeks—Not Years
Gene editors usually take years to test and perfect. KJ Muldoon’s treatment took only six months. Now his doctors want to go even faster. Before the age of one, KJ Muldoon had already made medical history. He was the first person to receive a gene editing therapy specifically designed for him. KJ was born with a deadly gene mutation. His body couldn’t remove ammonia, a byproduct of eating protein. The illness eventually leads to serious brain injury. Roughly half of infants with the disease don’
The science of consciousness
Humans know they exist, but how does “knowing” work? Despite all that’s been learned about brain function and the bodily processes it governs, we still don't understand where the subjective experiences associated with brain functions originate. A new interdisciplinary project seeks to find answers to these kinds of big questions around consciousness, a fundamental yet elusive phenomenon.The MIT Consciousness Club is co-led by philosopher Matthias Michel, the Old Dominion Care

Quantum teleportation between photons from two distant light sources achieved
Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography promises more effective protection. It makes communication secure against eavesdropping by relying on the laws of quantum physics. However, the path toward a quantum internet is still fraught with technical hurdles.
Show HN: Discussion of ICT Model – Linking Information, Consciousness and Time
Hi HN,I’ve been working on a conceptual framework that tries to formalize the relationship between:– informational states,
– their minimal temporal stability (I_fixed),
– the rate of informational change (dI/dT),
– and the emergence of time, processes, and consciousness-like dynamics.This is not a final theory, and it’s not metaphysics. It’s an attempt to define a minimal, falsifiable vocabulary for describing how stable patterns persist and evolve in time.Core ideas:– I_fixed = any pattern

Efficient quantum process tomography for enabling scalable optical quantum computing
Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple optical modes interact to generate quantum entanglement, has been considered an extremely challenging task.
Algorithm finds smallest dataset that guarantees optimal solutions to complex problems
Determining the least expensive path for a new subway line underneath a metropolis like New York City is a colossal planning challenge—involving thousands of potential routes through hundreds of city blocks, each with uncertain construction costs. Conventional wisdom suggests extensive field studies across many locations would be needed to determine the costs associated with digging below certain city blocks.
