How diamond fails under extreme electrical fields

A research team from the University of Chinese Academy of Sciences has revealed the failure mechanism of diamond under extreme electrical fields through in situ experiments and molecular dynamics simulations. The study, published in Cell Reports Physical Science, provides critical insights for the design of robust diamond devices.

Diamond is known for its exceptional physical properties, including ultra-high breakdown field strength and , making it a promising material for and high-power electronics. However, its failure process under extreme electrical fields has remained poorly understood before now.

Led by Profs. Yan Qingbo and Chen Guangchao, the researchers used an in situ transmission electron microscopy (TEM) method to observe the breakdown process in real time. They found that diamond failure begins preferentially along the (111) crystal plane due to stress-induced lattice distortion and subsequent amorphization, rather than transforming into graphite.

Microsoft’s new AI feature will organize your photos automatically

Microsoft has begun testing a new AI-powered feature in Microsoft Photos, designed to categorize photos automatically on Windows 11 systems.

Dubbed Auto-Categorization, it is currently limited to sorting screenshots, receipts, identity documents, and notes, and it’s rolling out to Copilot+ PCs across all Windows Insider channels with Microsoft Photos version 2025.11090.25001.0 or higher.

Microsoft says the feature utilizes a language-agnostic AI model that identifies document types regardless of the language used in the image. It works by grouping photos into predefined folders automatically, based on their visual content, such as handwritten notes, receipts, or printed documents.

CWM: An Open-Weights LLM for Research on Code

We release Code World Model (CWM), a 32-billion-parameter open-weights LLM, to advance research on code generation with world models. To improve code understanding beyond what can be learned from training on static code alone, we mid-train CWM on a large amount of observation-action trajectories from Python interpreter and agentic Docker environments, and perform extensive multi-task reasoning RL in verifiable coding, math, and multi-turn software engineering environments. With CWM, we provide a strong testbed for researchers to explore the opportunities world modeling affords for improving code generation with reasoning and planning in computational environments. We present first steps of how world models can benefit agentic coding, enable step-by-step simulation of Python code execution, and show early results of how reasoning can benefit from the latter.

The CRITICAL RoboTaxi Milestone Tesla Stock Investors CAN’T Ignore

Tesla’s upcoming robo-taxi milestone of deploying 2,000 vehicles is expected to significantly boost its margins and potentially double or triple its free cash flow, marking a critical point in the company’s expansion and growth ##

## Questions to inspire discussion.

Tesla’s Robo Taxi Strategy.

🚕 Q: What is Tesla’s approach to deploying robo taxis across the US? A: Tesla plans to seed robo taxis across multiple cities nationwide, rather than focusing on a single market, to demonstrate benefits to regional regulators, define drop-off and pickup zones, and establish presence before scaling up.

🏙️ Q: Which cities are part of Tesla’s initial robo taxi expansion plans? A: Tesla’s robo taxi expansion includes Austin, Bay Area, Nevada, Arizona, Florida, and other states, with Austin and Bay Area currently offering invite-only services.

Financial Impact and Pricing.

China develops fabric that withstands 2,192°F heat with ease

A Chinese company has showcased new types of fabrics that can withstand extreme temperatures. Some of the fabric materials presented were waterproof and windproof while remaining breathable.

Safmax presented these advanced fabrics at the second Public Security Tech Expo in Lianyungang, China.

The company’s new flame-retardant material can withstand temperatures up to 2,192 degree Fahrenheit (1,200 degrees Celsius). This fabric can maintain its structure without deforming, shrinking, or melting.

This type of fabric can be used in firefighting suits and fire blankets to isolate airflow during battery fires in new energy vehicles.

Robotaxi Wars Just Got BLOODY

Waymo’s partnership with Lyft in Nashville highlights advancements in robo-taxi safety, but the company faces significant challenges from Tesla’s established infrastructure and competitive landscape in the rapidly evolving autonomous vehicle market ## Questions to inspire discussion.

Tesla’s Robotaxi Advantage.

🚗 Q: How does Tesla’s manufacturing efficiency give it an edge in the robotaxi market? A: Tesla can build cars for one-third the price of competitors, with built-in Shepherds and the ability to manufacture at cost for FSD or robotaxi network use.

🌐 Q: What makes Tesla’s global expansion strategy unique? A: Tesla’s global approach and rapid execution allow it to go anywhere once FSD works, making it difficult for competitors to match its scale and speed.

🧠 Q: How significant is Tesla’s Full Self-Driving (FSD) technology? A: Tesla’s FSD is a gigantic advantage, with take rates tripling to double digits and expected to triple again, making it hard for others to compete.

Direct grid connection technology provides fast charging solution for electric vehicles

With the surging popularity for electric vehicles (EVs), rapid charging is a challenge as it requires power delivery exceeding 1 MW (which can power about 1,000 homes). Conventional charging stations rely on bulky line frequency transformers (LFTs), which are expensive due to extensive use of copper and iron. These stations also have multiple conversion stages involving stepping up or down current, or converting AC to DC and vice versa. This can greatly increase cost and reduce efficiency.

To solve this problem, researchers at the Department of Electrical Engineering (EE), Indian Institute of Science (IISc), in collaboration with Delta Electronics India, have developed a novel cascaded H-bridge (CHB)-based multiport DC converter that directly connects to the medium-voltage AC (MVAC) . This eliminates the need for large and expensive LFTs.

Published in IEEE Transactions on Industrial Electronics, the study shows that such converters can help address the growing power demands of fast-charging EV stations, crucial for scaling up India’s EV infrastructure.

New light-powered gears fit inside a strand of hair

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair. The research is published in the journal Nature Communications.

Gears are everywhere—from clocks and cars to robots and wind turbines. For more than 30 years, researchers have been trying to create even smaller gears in order to construct micro-engines. But progress stalled at 0.1 millimeters, as it was not possible to build the drive trains needed to make them move any smaller.

Researchers from Gothenburg University, among others, have now broken through this barrier by ditching traditional mechanical drive trains and instead using to set the gears in motion directly.
