- 3D atlas of human embryology
The 3D Atlas of Human Embryology project was funded by the Academic Medical Center (AMC) in Amsterdam, the Netherlands, in 2009. Since then, over 75 students, under the supervision of embryologists of the Department of Anatomy, Embryology & Physiology, have contributed to this labor-intensive project, investing over 45,000 hours of work. The result of this effort is an embryology atlas with more than 15,000 manually annotated sections and a duplicate series of fully reconstructed human embryos covering the phase of organogenesis, between Carnegie stage 7 (15–17 days old embryo) and 23 (56–60 days).

- Revised Estimates for the Number of Human and Bacteria Cells in the Body
Ron Sender, Shai Fuchs, and Ron Milo. PLoS Biol. 2016 Aug; 14(8): e1002533. Abstract Reported values in the literature on the number of cells in the body differ by orders of magnitude and are very seldom supported by any measurements or calculations. Here, we integrate the most up-to-date information on the number of human and bacterial cells in the body. We estimate the total number of bacteria in the 70 kg "reference man" to be 3.8·1013. For human cells, we identify the dominant role of the hematopoietic lineage to the total count (≈90%) and revise past estimates to 3.0·1013 human cells. Our analysis also updates the widely-cited 10:1 ratio, showing that the number of bacteria in the body is actually of the same order as the number of human cells, and their total mass is about 0.2 kg.
- Who’s Top Monkey? How Social Status Affects Immune Health
Catherine Caruso, Scientific American, November 24, 2016 A study published today in Science reveals that social status in macaques can actually impact their immune system, resulting in significant differences in immune function between high- and low-status monkeys in respect to their ability to respond to bacterial versus viral invaders.
