Scientists made a game-changing discovery about energy conversion in space.
Researchers have developed methods to explore and utilize superconductivity in non-equilibrium states, such as those induced by laser pulses, at temperatures much higher than traditional superconductors operate.
This light-induced superconductivity has been shown to replicate crucial features like zero electrical resistance and expulsion of magnetic fields, suggesting potential applications in high-speed devices and extending superconductivity to ambient temperatures.
Superconductivity is a remarkable phenomenon that enables a material to carry an electrical current with zero loss. This collective quantum behavior is unique to certain conductors and only occurs at temperatures significantly below room level.
Astronomers, led by Caltech’s Kareem El-Badry, have identified what could be 21 neutron stars orbiting stars similar to our sun—a rare discovery in the universe where most stars are found in pairs.
Ed Dwight could have been the only black astronaut in the 1960s – but politics got in the way. In 2024, at the age of 90, he finally got his chance to go into orbit.
Humanity has entered a new age of space tourism. For a minimum of $450,000 (£360,000), people with deep pockets can claim the title “astronaut” after a short sub-orbital flight to the edge of space and back and up to 10 minutes experiencing weightlessness above the Earth.
On these near-spaceflights, currently offered by Blue Origin and Virgin Galactic, there is usually one member of the crew whose name and story captures the headlines – and often a free ride.
The robotics startup provides a modular cell-based matrix structure through which an AI-powered bot navigates to move materials.

What Creates Consciousness?
Posted in futurism, robotics/AI
Renowned researchers David Chalmers and Anil Seth join Brian Greene to explore how far science and philosophy have gone toward explaining the greatest of all mysteries, consciousness–and whether artificially intelligent systems may one day possess it.
This program is part of the Big Ideas series, supported by the John Templeton Foundation.
Participants:
David Chalmers.
Anil Seth.
Moderator:
Brian Greene.

What is the nature of quantum physics? Neil deGrasse Tyson and comedian Chuck Nice get quantum, exploring Schrodinger’s Cat, electrons, Hilbert Space, and the biggest ideas in the universe (in the smallest particles) with theoretical physicist Sean Carroll.
When did the idea of fields originate? Are fields even real or are they just mathematically convenient? We explore electrons, whether they are a field, and whether they exist at all. We also discuss the wave function, Hilbert Space, and what quantum mechanics really is. Do superpositions always exist?
What would happen if Planck’s Constant were macroscopic? Learn about entangling particles and the longest entanglement distances. If the particles are entangled why would the distance matter? Could we make an internet with quantum entanglement? We break down Schrodinger’s cat, its interpretations, and what the thought experiment really means. Do superpositions always exist?
Are there quantum manifestations in the macro-universe? We explore the microwave background, inflation, and how we discovered that atoms are mostly empty. Sean gives his latest takes on dark matter, dark energy, emergence, and free will. Plus, is dark energy really the cosmological constant?
