The ability of C1q to bind to a variety of receptors has implications for signaling biology, spinal cord injury and, possibly, the evolution of the complement system.

Complement C1q directly drives the behavior of human neural stem cells via a classical receptor signaling mechanism modulating their capacity for functional integration in vivo.

20 emerging issues in bioengineering that will have profound impacts on society have been identified.

Mathematical modeling reveals that long-term immunological memory is maintained in a manner that is even more dynamic than previously thought.

Increasing awareness that many causal links in biology might be bi-directional could overcome biases and improve scientific reasoning.

Horizon scanning has been used to identify opportunities and risks presented by 20 emerging issues in the field of biological engineering.

Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.

A newly identified adipose lineage cell population, MALP, regulates marrow vasculature and osteogenesis in bone.

A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.
