Mechanically activated liquid metal powder lets users draw circuits on paper

Mechanochemically activated liquid metal powders for sustainable, reconfigurable electronics
Advanced Functional Materials (2025). DOI: 10.1002/adfm.202527396

What if electronic circuits could be created simply by drawing lines with a pencil on paper or leaves—and then immediately applied to soft robots or skin-attached health monitoring devices? Korean researchers have developed an electronic materials technology that forms electrically conductive liquid metal in a fine powder form, allowing circuits to be drawn directly on a wide variety of surfaces.

This technology presents new possibilities for next-generation flexible electronics, including applications on paper and plastic as well as in soft robotic systems and wearable devices. The research was published in Advanced Functional Materials.

The Small Magellanic Cloud (SMC) is one of the Milky Way’s closest galactic neighbors—a small, gas-rich galaxy visible to the naked eye from the southern hemisphere, and bound to our galaxy by gravity, alongside its companion, the Large Magellanic Cloud (1¹LMC). All three galaxies have been interacting for hundreds of millions of years.

The SMC is also one of the most studied galaxies in the sky. Astronomers have catalogued its stars, mapped its gas and tracked its motion for more than half a century. Yet a basic question about it has remained...

A research team led by Lee Hyun Jun and Noh Hee Yeon from the Division of Nanotechnology at DGIST has succeeded in implementing the world’s first two-terminal-based artificial intelligence (AI) semiconductor that precisely controls hydrogen with electrical signals to enable self-learning and memory. The team’s work appears in Advanced Science.

Whereas modern AI requires the rapid processing of vast amounts of data, the separation of computation and memory in conventional computers results in speed degradation and high power consumption...

Ryugu asteroid samples contain all DNA and RNA building blocks, bolstering origin-of-life theories

The black particles from an asteroid some 300 million kilometres away look unremarkable, but they hold components of life
The black particles from an asteroid some 300 million kilometers away look unremarkable, but they hold components of life.

All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday.

The discovery comes after these building blocks of life were detected on another asteroid called Bennu, suggesting they are abundant throughout the solar system.

One longstanding theory is that life first began on Earth when asteroids carrying fundamental elements crashed into our planet long ago.

The asteroids that hurtle through our solar system give scientists a rare chance to study this possibility.

In 2014, the Japanese spacecraft Hayabusa-2 blasted off on a 300-million-kilometer...
