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.

In South Africa, researchers have discovered a 100,000-year-old workshop that may have been used by early Homo sapiens to make, mix, and store ochre—the earliest form of paint.

The use of ochre, which is essentially just colorful dirt, has been well-documented after about 60,000 years ago. But these new findings show that early humans were using ochre much earlier than that, as well as producing and storing it.
