Ultrablack reflects less than 0.5% of light and is useful for cameras, solar panels, and telescopes but is hard to make and fades at angles, and researchers have now found a simple method to produce it. [...]

Norway is the world’s largest producer of farmed Atlantic salmon and a top exporter of seafood, while the United States remains the largest importer of these products, according to the Food and Agriculture Organization. Two MIT students recently traveled to Trondheim, Norway to explore the cutting-edge technologies being developed and [...]

Advancements in battery innovation are transforming both mobility and energy systems alike, according to Kurt Kelty, vice president of battery, propulsion, and sustainability at General Motors (GM). At the MIT Energy Initiative (MITEI) Fall Colloquium, Kelty explored how GM is bringing next-generation battery technologies from lab to commercialization, driving American [...]

Researchers developed an AI system that can reconstruct fine hand muscle activity using only standard video footage. Traditionally, this type of measurement required intrusive electrodes attached to the skin, but the new method eliminates that need entirely. [...]

Welcome back to The State of AI, a new collaboration between the Financial Times and MIT Technology Review. Every Monday for the next two weeks, writers from both publications will debate one aspect of the generative AI revolution reshaping global power. This week, Richard Waters, FT columnist and former West Coast [...]

Engineers have unlocked a new class of supercapacitor material that could rival traditional batteries in energy while charging dramatically faster. By redesigning carbon structures into highly curved, accessible graphene networks, the team achieved record energy and power densities—enough to reshape electric transport, stabilize power grids, and supercharge consumer electronics. [...]

Researchers unveiled a new technique that validates quantum computer results—especially those from GBS devices—in minutes instead of millennia. Their findings expose unexpected errors in a landmark experiment, offering a crucial step toward truly reliable quantum machines. [...]

A US telecom company trained an AI model on years of inmates’ phone and video calls and is now piloting that model to scan their calls, texts, and emails in the hope of predicting and preventing crimes.  Securus Technologies president Kevin Elder told MIT Technology Review that the company began building [...]

Thinking about upgrading your slow PC? Are you unsure how much RAM you actually need? Here's what this tech reviewer thinks. [...]

The OnePlus Watch 2 outperforms the Pixel Watch in several ways, with a long-lasting battery, a vibrant screen, and a durable design. Grab it at 33% off. [...]

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum internet. By creating nearly identical semiconductor-based photon sources and using frequency converters to sync them, researchers successfully transferred quantum states across a [...]

The discovery of strange, ultra-red objects—especially the extreme case known as The Cliff—has pushed astronomers to propose an entirely new type of cosmic structure: black hole stars. These exotic hybrids could explain rapid black hole growth in the early universe, but their existence remains unproven. [...]

Screen-printed MXene-cellulose labels deliver infrared QR authentication, reversible thermal switching, and rapid 200-second degradation, offering durable industrial anti-counterfeiting with reduced environmental persistence. [...]

The discovery was made by analysing sounds from the atmosphere of the red planet obtained by the Perseverance rover. [...]

Princeton researchers found that the brain excels at learning because it reuses modular “cognitive blocks” across many tasks. Monkeys switching between visual categorization challenges revealed that the prefrontal cortex assembles these blocks like Legos to create new behaviors. This flexibility explains why humans learn quickly while AI models often forget [...]

Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body. [...]

Separating AI reality from hyped-up fiction isn’t always easy. That’s why we’ve created the AI Hype Index—a simple, at-a-glance summary of everything you need to know about the state of the industry. Last year, the fantasy author Joanna Maciejewska went viral (if such a thing is still possible on X) with [...]

Large language models (LLMs) sometimes learn the wrong lessons, according to an MIT study.Rather than answering a query based on domain knowledge, an LLM could respond by leveraging grammatical patterns it learned during training. This can cause a model to fail unexpectedly when deployed on new tasks.The researchers found that [...]

More than 300 people across academia and industry spilled into an auditorium to attend a BoltzGen seminar on Thursday, Oct. 30, hosted by the Abdul Latif Jameel Clinic for Machine Learning in Health (MIT Jameel Clinic). Headlining the event was MIT PhD student and BoltzGen’s first author Hannes Stärk, who had announced [...]

Welcome back to The State of AI, a new collaboration between the Financial Times and MIT Technology Review. Every Monday, writers from both publications debate one aspect of the generative AI revolution reshaping global power. In this week’s conversation MIT Technology Review’s senior reporter for features and investigations, Eileen Guo, and [...]

A new study reveals African lions produce two types of roars, overturning long-held assumptions and opening the door to more precise wildlife monitoring. Using machine learning, researchers automatically distinguished between full-throated and newly identified intermediary roars with over 95% accuracy, eliminating much of the human bias in vocal identification. [...]

A new study demonstrates that an AI assistant can conduct psychiatric assessment interviews with greater diagnostic accuracy than widely used mental health rating scales. In a sample of 303 participants with confirmed psychiatric conditions, the AI assistant Alba provided DSM-based diagnostic suggestions after a brief conversational interview, outperforming rating scales [...]

Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations help explain how [...]

Aalto University researchers have developed a method to execute AI tensor operations using just one pass of light. By encoding data directly into light waves, they enable calculations to occur naturally and simultaneously. The approach works passively, without electronics, and could soon be integrated into photonic chips. If adopted, it [...]

Researchers have created a prediction method that comes startlingly close to real-world results. It works by aiming for strong alignment with actual values rather than simply reducing mistakes. Tests on medical and health data showed it often outperforms classic approaches. The discovery could reshape how scientists make reliable forecasts. [...]
