Scientists Create Human Embryo-Like Structures with Stem Cells

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy. Historically, international rules prevent research on human embryos more than 14 days after fertilization. But the new technique uses stem cells, which have the potential to transform… Continue reading Scientists Create Human Embryo-Like Structures with Stem Cells

Sparse Neural Networks Point Physicists to Useful Data

Graham tried tweaking the CNN approach so that the kernel would only be placed on 3-by-3 sections of the image that contain at least one pixel that has nonzero value (and is not just blank). In this way, he succeeded in producing a system that could efficiently identify handwritten Chinese. It won a 2013 competition… Continue reading Sparse Neural Networks Point Physicists to Useful Data

Brain Waves Synchronize when People Interact

Neuroscientists usually investigate one brain at a time. They observe how neurons fire as a person reads certain words, for example, or plays a video game. As social animals, however, those same scientists do much of their work together—brainstorming hypotheses, puzzling over problems and fine-tuning experimental designs. Increasingly, researchers are bringing that reality into how… Continue reading Brain Waves Synchronize when People Interact

The Case for a Governance-First U.S. Security Policy in the Sahel

Both terrorism and coups are on the rise in the Sahel. This is a troubling trend that the United States should be working to reverse.

This will require… Continue reading The Case for a Governance-First U.S. Security Policy in the Sahel
