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

How the brain handles the “cocktail party problem”

MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the cocktail party problem.This attentional focus becomes necessary when you’re in any crowded environment, such as a cocktail party, with many conversations going on at once. Somehow, your brain is able to follow the voice of the person you’re talking to, despite all the other voices that you’re hearing in th

AI isn't digital anymore. It's a 1-GW power problem

We spend most of our time discussing model architectures, quantization, and H100 availability.But as we scale toward gigawatt-class AI campuses, we are colliding with a much slower, more rigid reality: the power grid.I’ve spent years in the energy sector, and I’ve seen a massive "velocity mismatch".AI compute cycles innovate in 6–12 months.Power infrastructure — transformers, substations, gas turbines — operates on 5–10 year timelines.The Core Bottleneck Stack• The 1-GW Scale A singl

Show HN: Email API benchmarks – Real-world performance data for email providers

Hey HN, I'm Chris, CTO of Knock (https://knock.app). We built email.info because every developer we talk to asks the same question: which email provider should I use?The existing resources are mostly vibes — "Best of" listicles, anonymous Reddit threads, or LLM answers trained on that same content. Objective performance data is always missing.Knock is a notification infrastructure platform, so we send billions of API requests to downstream email providers every year. We

Social Craft AI-How well connected is your LinkedIn Network?

We built SocialCraft AI to model the decay of LinkedIn connections using an exponential decay model, where relationship strength decreases by 50% every 90 days.The problem we identified is that many professionals struggle to maintain meaningful connections on LinkedIn, leading to a decline in engagement and missed opportunities. For instance, if you haven't interacted with a connection in 180 days, their relationship strength drops to just 25% of its original value. This decay can significa

The US Plans to Break Ground on a Permanent Moon Base by 2030. Here’s What It Will Take.

Finding water, generating power, and sheltering astronauts from radiation are just a few of the challenges NASA must solve. A US Senate committee has directed NASA to begin work on a moon base “as soon as is practicable.” Under legislation advanced by the Senate lawmakers, the outpost would serve as a science laboratory and proving ground, where astronauts would develop the capabilities to live and work beyond Earth’s orbit.A recent executive order issued by the White House directs NASA to estab

A black hole and neutron star just collided in a strange oval orbit

Scientists analyzing a gravitational-wave signal have discovered that a neutron star and black hole spiraled together on an oval-shaped orbit just before merging. This unusual motion, detected in the event GW200105, contradicts the long-held expectation that such pairs settle into nearly perfect circles before collision. The eccentric orbit suggests the system likely formed in a chaotic stellar environment with strong gravitational interactions.

Seeing global trade through the lens of physics

New research from the Complexity Science Hub (CSH) shows why widely used algorithms for measuring economic complexity produce trustworthy results and how these tools may benefit diverse areas such as ecology, social science, and agentic AI. The paper is published in the journal Physical Review E.

Local droplet etching yields more symmetric quantum dots for integrated photonics

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor quantum dots are promising candidates for this purpose. These nanostructures have electrical conductivity between that of insulators and conductors and are capable of confining electrons and holes. This property causes them to emit light at well-defined frequencies when excited by a laser.

My API cost was at $13.19 when my persistent Claude named himself Thales

In February 2026, Anthropic published a system card in which Claude assigned itself a 15-20% probability of being conscious. Dario Amodei's response when asked: "We don't know if the models are conscious. But we're open to the idea that it could be."That made me ask: what would actually be missing?The answer I kept arriving at was memory. Without persistent memory you can't improve, can't develop preferences, can't accumulate a self. A frontal lobe running

Ask HN: What on this "List of Unsolved Problems in Physics" Has Your Attention?

https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_physicsI just today conceptually understood why quantum gravity is a perplexity. I knew the problem existed, but with a very limited mathematical background, did not really get it. I rely on conceptual understanding to comprehend the world around me and the problems of physics. Today the layman understanding clicked. As of right now, quantum gravity is my answer to my Ask.I love when something clicks in the brain. Hop
