Xi Jinping to Make First In-Person Appearance at World AI Conference

The Indian government is currently reviewing replies from messaging apps WhatsApp, Telegram, and Signal regarding a proposal to introduce usernames. The Ministry of Electronics and Information Technology (MeitY) had earlier sent notices to these platforms expressing concerns over username-based messaging. The government is considering implementing uniform rules for such features across all messaging services in the country. The proposal aims to enhance user identification and potentially improve accountability. However, privacy advocates worry that mandatory usernames could compromise anonymity. The apps have submitted their responses, and the government is now assessing them. A decision on whether to enforce uniform regulations is expected soon. This move is part of India's broader efforts to regulate digital platforms and ensure compliance with local laws. The outcome could impact how millions of Indians use these messaging services daily.

Recycling electric vehicle batteries is often more expensive than the value of the materials inside. This creates a dilemma for the environment and the industry. Used batteries may pile up or be disposed of improperly. To address this, the state of Colorado has passed a new law. The law aims to make battery recycling economically viable. It includes measures such as financial incentives for recyclers and requirements for battery producers to fund recycling programs. The goal is to reduce waste and support the growing EV market. Supporters believe this will encourage more recycling and lower costs over time. The law is one of the first in the U.S. to tackle the economic challenges of EV battery recycling. It could serve as a model for other states. While details are still being worked out, the law marks a significant step toward a more sustainable electric vehicle industry. Recycling batteries properly is important because they contain valuable metals like lithium, cobalt, and nickel. It also prevents toxic materials from harming the environment. Colorado's approach focuses on sharing the costs among manufacturers, recyclers, and consumers. The hope is that as recycling becomes cheaper, more batteries will be recycled instead of thrown away. This could help reduce the need for mining new materials.

In the war in Ukraine, a new kind of soldier is emerging: robots. What started as simple machines to carry supplies has turned into a small army of ground vehicles that now rescue wounded soldiers, hold defensive positions, and even attack enemy troops. This shift is reshaping how battles are fought, with robots taking on roles that were once only for humans. Military experts say these machines are becoming more common because they can operate in dangerous areas without risking lives. Some are remote-controlled, while others use sensors to move on their own. They are used for tasks like scouting, bomb disposal, and direct combat. The change is happening quickly. Early in the war, robots mainly helped move gear. Now, soldiers report seeing unmanned vehicles in trenches and near front lines. Both Ukrainian and Russian forces are using them. The technology isn't perfect yet—robots can get stuck or lose connection—but they are improving fast. This trend could change future wars, making them more automated and less dependent on human soldiers for dangerous jobs. The world is watching as Ukraine becomes a testing ground for robot warfare.

European scientists have introduced a new rocket design called the RLV C5, which is meant to be partially reusable. This project aims to give Europe a way to launch heavy payloads into space while reducing costs. The RLV C5 uses liquid hydrogen and oxygen as fuel, making it more efficient than some older designs. A key feature is that its booster stage will glide back to Earth after launch and be caught in mid-air by an aircraft. This method is intended to make the rocket simpler and cheaper to build and operate. Currently, SpaceX's Starship is a leading reusable rocket, and Europe hopes to compete with this new concept. The proposal comes from a group of European researchers who believe this approach could lower the barriers to space access for the continent. The RLV C5 is still in the concept phase, but it shows Europe's interest in developing its own reusable launch technology. Reusable rockets are important because they can be flown multiple times, which reduces the cost per launch. This makes space missions more affordable for both government and commercial customers. While the RLV C5 is not yet built, it represents a step forward in Europe's space ambitions.

China has reportedly built a working prototype of an extreme ultraviolet (EUV) lithography machine, a key tool for manufacturing the world's most advanced computer chips. This development challenges long-held assumptions that China lagged far behind in semiconductor technology. EUV machines are extremely complex and are currently only produced by the Dutch company ASML. They use powerful laser pulses to create tiny patterns on silicon wafers, enabling the production of chips with billions of transistors. According to experts, China's prototype combines domestic innovations with components obtained through secret procurement networks. While the prototype is not yet ready for mass production, analysts believe China could achieve commercial-scale EUV lithography by 2030. If successful, this would mark a major shift in the global semiconductor landscape, reducing Western dominance in chip manufacturing and potentially reshaping supply chains. However, significant challenges remain, including the need for high-precision optics, stable power sources, and advanced materials. The news comes amid ongoing US-led restrictions aimed at limiting China's access to advanced chip technology. China's breakthrough, if confirmed, would show that these restrictions have not fully stopped its progress.

Chinese researchers have developed a new type of chip connection that uses light instead of electricity to link standard computer chips. This optical system speeds up artificial intelligence tasks by more than 100 times while using only about one-ninth of the normal computing power. The breakthrough could help solve the growing problem of energy consumption in AI data centers. As AI models become more common in everyday life, they require enormous amounts of computing power. Currently, companies build larger data centers and add more graphics processing units (GPUs) to meet this demand. But this approach uses huge amounts of electricity and generates a lot of heat. The new all-optical interconnect system works by transmitting data using light pulses between chips. This is much faster and more efficient than traditional electrical connections. In tests, the system performed distributed inference—where multiple chips work together to run an AI model—over 100 times faster than current methods. The researchers say this technology could reduce the energy and hardware needed for AI computing. It may also help make AI systems faster and more accessible without requiring massive data centers. The work was published in a Chinese scientific journal and is seen as a major step forward in optical computing.
