World’s largest fusion reactor gets final 485-ton vacuum vessel sector

ITER, the world’s largest nuclear fusion reactor, reached a major milestone in its decades-long journey after a European consortium delivered the final vacuum vessel sector on site. The vacuum vessel is also known as the plasma chamber and will be home to fusion reactions while also acting as the first containment barrier for the reactor.

In our bid to move away from fossil fuels, scientists are working to replicate the reactions that occur in stars and release large amounts of carbon-free energy in the process. Called nuclear fusion, the process is considered advantageous over its fission counterpart, since it does not generate large amounts of radioactive waste.

However, nuclear fusion research is still in its infancy, and scientists are working to create reactions that can be sustained for long durations. ITER is the world’s largest nuclear fusion experiment that is working to sustain nuclear fusion reactions inside a tokamak, or donut-shaped, reactor vessel.

FCC approves SpaceX’s 15,000-satellite Starlink Mobile constellation promising 150Mbps to phones

The FCC has approved SpaceX’s application to launch and operate 15,000 next-generation satellites for Starlink Mobile and granted a waiver that lets the company sell satellite wireless service without leasing spectrum from a terrestrial carrier. SpaceX says the constellation will deliver 5G speeds of up to 150Mbps per user.

Microsoft and Nvidia Join Forces to Reshape the PC

Microsoft and Nvidia took the stage together at a Windows event in San Francisco on October 8 to unveil the next phase of the personal computer. In a rare joint appearance, the two companies’ CEOs announced a sweeping collaboration spanning operating system security architecture to hardware design, with the goal of making AI agents the core computing entities within the Windows ecosystem.

Nvidia CEO Jensen Huang made clear during the conversation that the personal computer, once a tool for humans, will in the future serve both people and AI agents. He pointed out that agents have the potential to utilize software capabilities far more fully than humans, since users typically only know 10% to 15% of an application’s features, whereas an agent can master every function.

Microsoft CEO Satya Nadella framed the collaboration as a paradigm shift in computing. He noted that when agents begin directly manipulating files, applications, and cloud services, the operating system must be redesigned to allow agents to execute tasks safely and efficiently.

Introducing Playground: Create and play custom games

Games are one of the most creative forms of expression, and the gaming community keeps growing. But game creation has historically been limited to a select group of people who have technical experience and knowledge of complex game engines.

Today, we’re introducing Playground, an experimental gaming platform that lets you create, play, and share custom games. Playground lowers the barriers to creation, so bringing game ideas to life can now be as easy as describing it through a few prompts — no coding experience required.

With Playground’s conversational interface, you can direct the game just by typing what you want to build. Start from a blank canvas, remix starter prompts, or use guided support to shape your concept — and then test it right away. Want to tweak the physics, rewrite the rules, customize the characters, or overhaul the environment? Just ask. You stay in complete control of the creative direction from rough concept to final product.
