A research team has developed the world’s first next-generation betavoltaic cell by directly connecting a radioactive isotope electrode to a perovskite absorber layer. By embedding carbon-14-based quantum dots into the electrode and enhancing the perovskite absorber layer’s crystallinity, the team achieved both stable power output and high energy conversion efficiency.

The work is published in the journal Chemical Communications. The team was led by Professor Su-Il In of the Department of Energy Science & Engineering at DGIST.

The newly developed technology offers a stable, long-term power supply without the need for recharging, making it a promising next-generation energy solution for fields requiring long-term power autonomy, such as , , and military applications.

A giant object that has been lurking in the relative galactic vicinity of the Solar System this entire time has just been unmasked in all its enormous, invisible glory.

Just 300 light-years away, at the edge of the Local Bubble of space, astronomers have discovered a huge, crescent-shaped cloud of molecular hydrogen, the basic building block of everything in the Universe.

It’s the first time scientists have managed to discover molecular material in interstellar space by looking for the glow of far-ultraviolet light. Its discoverers have named the cloud Eos, after the ancient Greek goddess of the dawn.

“Second Variety” is a science fiction novelette by American writer Philip K. Dick, first published in Space Science Fiction magazine, in May 1953. Set in a world where war between the Soviet Union and United Nations has reduced most of the world to a barren wasteland, the story concerns the discovery, by the few remaining soldiers left, that self-replicating robots originally built to assassinate Soviet agents have gained sentience and are now plotting against both sides. It is one of many stories by Dick to examine the implications of nuclear war, particularly after it has destroyed much or all of the planet. The story was adapted into the movie Screamers in 1995. 00:00 Intro 01:03 Peek into the plot 03:33 Self-Replication and Technological Autonomy 06:51 Current Autonomous Warfare Capabilities 10:30 Space Warfare and the Projection of Terrestrial Conflict 13:14 Current State of Space Warfare 15:22 Wrapping Up =============== 🎬 Loitering munitions system WARMATE • Loitering munitions system WARMATE 📙 🇺🇸 Superintelligence: Paths, Dangers, Strategies https://bookshop.org/a/98861/97801987… The Human Terrain Project — PENTAGON’S attempt to understand The Enemy | ENDEVR Documentary • The Human Terrain Project — PENTAGON’… 📙 🇺🇸 War in the Age of Intelligent Machines https://monoskop.org/images/c/c0/DeLa… =============== Buy the book featured in this video: 📙 🇺🇸 Buy the book Second Variety https://bookshop.org/a/98861/97988883… 🎧 Free Audiobook • Post-Apocalyptic Story “Second Variet… =============== You can find my take on things summarised in the books I wrote. 📙🇺🇸Chronicles of the Machine — Simulated conversations with Philip K.

Scientists are using cutting-edge techniques to track water ice on the Moon—an essential resource for future space missions.

A University of Hawai‘i team utilized ShadowCam to peer into the Moon’s perpetually dark craters, refining estimates of surface ice. Another team introduced a cosmic ray-based method to detect deeply buried ice, a breakthrough in lunar exploration. Both approaches could revolutionize how we locate usable water beyond Earth, with Hawai‘i emerging as a key player in the growing space frontier.

Unlocking lunar water: why ice on the moon matters.
