The top sphere contains the part that will become the embryo itself, capped by the amnion; the bottom sphere is the yolk sac; the interface between them is a critical structural feature of human embryonic development. The two spheres are encapsulated by a cellular layer that will become the placenta.
Scientists built the model embryo, imaged here. The outer ring is the placenta forming.

Scientists genetically engineer bacteria to detect cancer cells

Engadget

An international team of scientists has developed a new technology that can help detect (or even treat) cancer in hard-to-reach places, such as the colon. The team has published a paper in Science for the technique dubbed CATCH, or cellular assay for targeted, CRISPR-discriminated horizontal gene transfer.
