Learning, remembering something, and recalling memories is supported by multiple separate groups of neurons connected inside and across key regions in the brain. If these neural assemblies fail to sync together at the right time, the memories are lost, a new study has found.

It may be better to let a mild fever run its course instead of automatically reaching for medication, new University of Alberta research suggests. Researchers found that untreated moderate fever helped fish clear their bodies of infection rapidly, controlled inflammation and repaired damaged tissue. Moderate fever is self-resolving, meaning that the body can both induce it and shut it down naturally without medication. The health advantages of natural fever to humans still have to be confirmed through research, but the researchers say because the mechanisms driving and sustaining fever are shared among animals, it is reasonable to expect similar benefits are going to happen in humans.

A global maternal immunization program for group B Streptococcus -- strep B -- would save millions in healthcare costs by reducing death and disability, but without tiered pricing, equitable access would likely not be achieved. Several vaccines are currently under development, and an assessment of the impact and value of a global program has now been published.

We all know how important sleep is for mental health, but a meta-analysis found that getting good shut-eye also helps our immune systems respond to vaccination. The authors found that people who slept less than six hours per night produced significantly fewer antibodies than people who slept seven hours or more, and the deficit was equivalent to two months of antibody waning.
