After Haiti’s devastating earthquake, a AAAS report laid out a vision for advancing science and education in Haiti, as a foundation for the country’s more stable, prosperous future. Four years later, efforts to strengthen Haitian science and technology are gaining ground, though more work remains ahead.

Researchers in Texas have discovered thousands of human artifacts in a layer of earth that lies directly beneath an assemblage of Clovis relics, expanding evidence that other cultures preceded the Clovis culture in North America. This pre-Clovis toolkit appears to be between 13,200 and 15,500 years old and it includes biface and blade technology that may have later been adapted—and improved upon—by the Clovis culture.
