Granular contact models
The most commonly used particle models include Hertz-Mindlin with JKR, Hertz-Mindlin with Bonding, and Hertz-Mindlin (no-slip). The Hertz-Mindlin with JKR model accounts for surface adhesion forces and is ideal for fine…

AI models can make own social norms, form language without human help
Researchers have revealed that the LLM AI models can spontaneously develop shared social conventions through interaction alone. They claimed that when these agents communicate in groups, they do not just follow scripts or repeat patterns, but…

Microbes capture CO2, developed this trait by adopting harsh conditions
Researchers have discovered a microbe that can capture carbon dioxide quickly, and it sinks, essentially sequestering concentrated carbon dioxide.
Nicknamed Chonkus, the microbe is a type of cyanobacteria, which feeds on carbon dioxide through…
