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 promis...

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...

Researchers uncover a surprising survival strategy that could reshape biotech and energy systems. A team led by Rice University bioscientist Caroline Ajo-Franklin has discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen. The findings, published in Cell last month, could enable new developments in clean energy and industrial biotechnology.

By identifying how these bacteria expel electrons externally, the researchers offer a glimpse into a previously hidden strategy of bacterial life. This work, which merges biology with electrochemistry, lays the groundwork for future technologies that harness the unique capabilities of these microscopic organisms.
