In a key step toward making large-scale optical neural networks practical, researchers have demonstrated a first-of-its-kind multilayer all-optical artificial neural network. Researchers detail their two-layer all-optical neural network and successfully apply it to a complex classification task.

A study has revealed the effects of the stress of parenting in the brains of both mothers and their children. The researchers analyzed the brain activity of 31 pairs of mother and child from Singapore while they were watching children’s animation clips together.

Researchers have embarked on a treasure hunt into China’s biodiversity hotspots, including the descriptions of 23 species previously unknown to science and new insights into the ecological diversity of ferns based on their DNA sequences.
