However, just because molecules could form doesn’t mean that the process was likely. Now, researchers have demonstrated that energetically feasible interactions between just two small molecules — hydrogen cyanide and […]

Flexible tool use is closely associated to higher mental processes such as the ability to plan actions. Now a group of cognitive biologists and comparative psychologists found out that the apes carefully weighed their options.

The third eye… Light… Darkness…
Just like land plants, algae use sunlight as an energy source. Many green algae actively move in the water; they can approach the light or move away from it. For this they use special sensors (photoreceptors) with which they perceive light. The decades-long search for these light sensors led to a first success in 2002: […]

AI. Games. Intelligence. Humans.
Artificial Intelligence is constantly beating humans in more and more board games. Some years ago, the same team that created that Go-playing bot celebrated something more formidable: an artificial intelligence system that is capable of teaching itself—and winning at—three different games. The AI is one network, but works for multiple games; that generalizability makes it […]
