When a pathogen invades the body, the immune system has to identify it and mount a response, which involves inflammation. That inflammation may be local, but it can also become widespread throughout the body. The immune system must be carefully regulated, or such inflammation can spiral out of control, and create a life-threatening situation known as sepsis.

Socioemotional behavior at age 8 predicts health behavior through education in midlife. The corresponding study was published in Psychology and Health. For the study, researchers used data from the Jyväskylä Longitudinal Study of Personality and Social Development, an ongoing study that began in Finland in 1968. They followed participants from age 8 to age 50. Altogether, there were 369 participants at the beginning of the study, and 271 at the end.

New research is changing what we thought we knew about a common brain receptor in the brain. Glutamate receptors modulate most of the excitatory neural activity in the central nervous system. The glutamate receptor itself has several layers. When glutamate is bound, ion channels on the structure open, conducting ions and electrical charge through the channel; neural signals are propagated using those electrical charges. Disruption in glutamate receptors has been implicated in many disorders.
