Autonomous AI assistant to build nanostructures
The chemical composition of a material alone sometimes reveals little about its properties. The decisive factor is often the arrangement of the molecules in the atomic lattice structure or on the surface of the material. Materials science…

Synchronization in neural nets: Mathematical insight into neuron readout drives significant improvements in prediction accuracy
Researchers applied the mathematical theory of synchronization to clarify how recurrent neural networks (RNNs) generate predictions, revealing a certain map, based on the generalized synchronization, that yields correct target values. They showed…

Ancient, engraved stones may have been buried to summon the sun
As a volcanic eruption darkened the sun roughly 4,900 years ago, a Stone Age culture sacrificed hundreds of decorated stone plaques to try to coax it back.
A trove of engraved stones unearthed from ritual gathering sites on Bornholm,…

Stanford Researchers Produce Ammonia Fuel From Thin Air
Lots of green energy experiments in the lab publish impressive results—but what’s more impressive is when those results come from an actual on-site pilot demonstration in the real world. That’s the case with new research that is able to…

New Research Explores Decision-Making Processes of Early Hominin Tool-Makers
Paleoanthropologists have characterized the properties of raw stone materials that were selected and used by Early Pleistocene tool-makers at an Acheulian site in the Ethiopian Highlands between 1.6 and 1 million years ago.
Handaxes made on…
