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

RoboticsHow Pokémon Go Is Giving Delivery Robots an Inch-Perfect View of the WorldWill Douglas Heaven | MIT Technology Review ($)“Niantic Spatial is using that vast and unparalleled trove of crowdsourced data—images of urban landmarks tagged with super-accurate location markers taken from the phones of hundreds of millions of Pokémon Go players around the world—to build a kind of world model, a buzzy new technology that grounds the smarts of LLMs in real-world environments.”FutureA R

Pi Day: From rockets to cancer research, here's how the number pi is embedded in our lives

Math nerds and dessert enthusiasts unite to celebrate Pi Day every March 14, the date that represents the first three digits of the mathematical constant pi.

A lab mistake at Cambridge reveals a powerful new way to modify drug molecules

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment.

These Genetically Engineered Brain Cells Devour Toxic Alzheimer’s Plaques

A single shot protected mice from the protein gunk implicated in Alzheimer’s disease. Alzheimer’s disease and cancer have something in common: They’re hard to treat.Despite decades of research, both still plague humanity, robbing people of longer, healthier lives. In Alzheimer’s, a protein called amyloid forms toxic clumps in the brain. Eventually, neurons supporting memory, decision-making, and movement wither.Whether amyloid clumps cause Alzheimer’s is still hotly debated. Drugs that cle

We Need to Look into Machine Cognition

I’ve been thinking a lot about how we actually form ideas.When we speak, it often feels like the words simply arrive. One word leads to the next, then the next, until eventually we reach the end of a thought. It’s an iterative process — a step-by-step stream of language emerging in real time.But that raises a deeper question.Is speaking itself the process of thinking? Or is it simply the surface output of a deeper process happening outside our awareness?It often feels like the latter.Ideas seem

Quantum spin study reveals a previously unknown state of matter

At temperatures approaching absolute zero, most magnetic materials settle into tidy patterns. Their tiny magnetic moments, or spins, align in one of two ways: all pointing in the same direction in ferromagnetic order, or alternating neatly in an antiferromagnetic pattern.

The spec said "handle user input securely." Three teams interpreted this differently.Team A built a fortress - every form field got sanitized, validated, escaped, then re-validated. User registration takes 47 seconds but by god it's bulletproof.Team B went minimalist - "security through simplicity." Strip everything to alphanumeric. Emoji? Denied. Apostrophes? Suspicious. John O'Brien becomes JohnOBrien and learns to live with it.Team C implemented quantum security
