IN A NUTSHELL 🌟 Scientists at Japan’s RIKEN Center for Advanced Photonics have discovered that carbon nanotubes can emit more energetic light than they absorb. 🔍 The phenomenon, known as up-conversion photoluminescence (UCPL), occurs even in pristine nanotubes, defying previous theories requiring structural defects. ☀️ This discovery holds potential for enhancing solar energy efficiency by.
Quantum error correction of a logical qutrit and ququart were experimentally realized beyond the break-even point with the Gottesman–Kitaev–Preskill bosonic code.

Nvidia CEO Jensen Huang made a slew of announcements and revealed new products on Monday, aiming to sustain its leadership in AI computing.
Scientists have discovered 866 new marine species, including a guitar shark, a deep-sea mollusk with cancer treatment potential, and the first octocoral found in the Maldives, Oceanographic Magazine reported.
The Nippon Foundation-Nekton Ocean Census looks to change how scientists identify new marine species by speeding up the process. This discovery marks a “significant step” in advancing our understanding of ocean biodiversity. Traditional methods can take up to 14 years, but this international collaborative effort of 800 scientists from over 400 institutions is changing the approach.
Many species go extinct before they’re documented. The mission’s executive director explained that while oceans cover 71% of our planet, only about 10% of marine life has been discovered. By accelerating identification, scientists can better protect these species.
The GitHub Copilot assistant, which recently gained an agent mode feature to help it compete with Cursor and Windsurf, now has over 15 million users, four times more than a year earlier, Microsoft CEO Satya Nadella told analysts on a conference call earlier this month.
A free Copilot tier for individuals provides limited access.
The new coding agent won’t be free, though. It will be available to developers with Copilot Pro+ subscriptions and organizations that subscribe to the Copilot Enterprise service tier, GitHub said. It’s available in preview, meaning that GitHub will take early user feedback, the spokesperson said.
This breakthrough in battery power could bring wearable tech, implanted medical devices, and humanoid robots to life.
Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes.
The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or a pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds.
Enormous structures resembling bones or snakes are found near the center of the galaxy. These elongated formations are seen in radio waves and are threaded by magnetic fields running parallel to them. The radio waves are caused by energized particles spiraling along the magnetic fields.
Did the universe really start with a Big Bang? Dr. Richard Lieu thinks otherwise. In this episode, we explore his radical theory of transient temporal singularities—bursts that could replace dark matter, dark energy, and even the Big Bang itself. Get ready to rethink the universe.
