Nvidia cedes the throne to Apple
Apple has once again dethroned Nvidia as the world’s most valuable company after the chip giant fell 4.99% on Wall Street, and following reports that it is negotiating a $250 billion investment with OpenAI for a data center project.
Apple rose 1.17% to reach a market capitalization of $4.93 trillion, while Nvidia fell 4.99% to $4.78 trillion.

AI redesigns proteins
Scientists at Duke University School of Medicine, in the U.S., have developed an AI capable of redesigning proteins without sacrificing their function and while preserving their structure, a topic that has been under investigation since 2024 but is now published in detail in the journal Nature.
According to the authors, this opens up new possibilities for protein engineering that would be used in biological research and, ultimately, to develop targeted drugs in the future. Proteins, which are chains of hundreds of amino acids that perform a large part of the activities that allow cells to survive, are necessary for the function and regulation of tissues and organs.

U.S. tech companies for an open and safe AI
Open Secure AI Alliance is an initiative led by tech companies Nvidia, Microsoft, and Palantir to strengthen the security of open AI, amidst the ongoing struggle between the U.S. and China for leadership in the field. The alliance seeks to “develop and share open tools to identify and fix vulnerabilities” in AI, as well as “improve response capabilities to threats,” Nvidia reported in a statement.
The tech company, which is leading the idea, added that “AI safety” also depends on “systems that allow researchers and developers to inspect, adapt, and run” advanced tools on their own infrastructure.

A ‘Video-selfie’ will sign you into Google
Google announced the ‘video-selfie’ as a new login method, designed to offer more access options in case the user gets locked out of their accounts. “We compare your video with the saved selfie and ask you to perform simple movements to prove that it is a real-time video,” the tech company reported.
When using a selfie to log in, Google employs “multiple layers of security to help prevent spoofing attempts using fake photos or videos such as ‘deepfakes’,” the company noted.
ChatGPT helps you with your health, but it was sued
OpenAI, creator of ChatGPT, announced the launch of Health, a new feature that allows users in the U.S. to connect their health information so the platform can help them understand and manage their medical history. This way, the AI can compare new results with previous tests, summarize changes that have occurred since the most recent medical appointment, or explore how sleep and activity relate to the patient’s daily routine.
However, it was also learned that a ChatGPT user filed a negligence lawsuit against OpenAI and its CEO, Sam Altman, arguing that the chatbot discouraged him from seeking medical treatment when he consulted it about symptoms of an illness that could have cost him his life.
Europe imposes two key fines on Google
The European Commission imposed two fines on Google totaling 890 million euros for prioritizing its own services in the search engine and preventing mobile application developers from informing users, free of charge, about cheaper offers outside of Google Play.
The EU Executive considers that these practices infringe the Digital Markets Act (DMA), which regulates fair competition among large tech companies in the EU, and also demands they be ended within 60 days or there will be additional periodic fines.
