Cosmic Dust May Have Brought Life’s Building Blocks to Earth

Scientists propose that cosmic dust, rather than large asteroids, delivered the essential amino acids that sparked life on Earth. With 40,000 tons of dust reaching Earth annually, this mechanism offers a more probable explanation for life’s building blocks. Recent experiments confirm certain amino acids can survive space conditions when attached to dust particles.

New research suggests that life on Earth</ may have originated from microscopic cosmic dust particles carrying essential organic compounds, challenging the long-held theory that asteroids delivered these building blocks. According to a study published in the Monthly Notices of the Royal Astronomical Society, the sheer volume of dust reaching Earth annually makes this a statistically more probable mechanism for seeding our planet with life’s fundamental components.

** What This Year’s Nobel Prize Teaches About Innovation And AI Risk

** This year’s Nobel Prize in economics reveals crucial insights about AI risk and innovation. The laureates’ research shows technological progress inevitably creates winners and losers, offering vital lessons for navigating AI’s societal impacts. Understanding these dynamics is key to managing AI’s disruptive potential. **CONTENT:**

This year’s Nobel Prize in economics offers profound insights about AI risk and technological innovation that every policymaker should understand. As someone working in AI policy, I frequently encounter existential fears about artificial intelligence, but the real danger lies in society’s inability to adapt to rapid technological change. The 2025 economics laureates—Joel Mokyr, Philippe Aghion, and Peter Howitt—provide the framework for understanding why innovation creates both prosperity and conflict, with direct applications to today’s AI debates. Their collective work demonstrates that managing technological transition, not preventing progress, represents our greatest challenge.

MIT Researchers Advance Nuclear Fusion With AI-Powered Plasma Control Model

MIT researchers have created a physics-informed machine learning model that predicts plasma behavior in fusion reactors. This breakthrough addresses one of nuclear fusion’s biggest challenges: safely controlling plasma during reactor shutdowns.

Scientists at the Massachusetts Institute of Technology have taken a significant step toward scaling up nuclear fusion energy by developing an AI-powered model that predicts plasma behavior in tokamak reactors. This breakthrough addresses one of the most persistent challenges in making fusion power commercially viable: safely controlling plasma during reactor shutdowns.
