This week's NSF Science 360 highlights include insights into how humans navigate using mental maps and internal compasses, which function independently. Researchers have also made strides in assembling DNA nanostructures without water, potentially advancing nanotechnology and understanding life's origins. Additionally, climate scientists are examining cave deposits to uncover prehistoric climate changes, focusing on how past temperatures influenced monsoon patterns, crucial for millions relying on this rainfall.
