Microfluidic systems redefined biology by providing platforms that handle small fluid volumes, catalyzing advancements in cellular and molecular studies.
A single amino acid substitution in a protein causes increased neuron production in the frontal lobes of humans compared to Neanderthals—a tiny difference that could have given our species a cognitive edge, researchers say.
If we ask the right questions, modern tools could help researchers solve mysteries such as why many people believe in a God that both provides unconditional love and levies eternal damnation.
