E. coli infection induces delirium in aging rats: Research could inform understanding of how immune system activation affects cognitive function in the elderly

Activation of the immune system by an infection may temporarily disrupt formation of long-term memories in healthy, aging rats by reducing levels of a protein required for brain cells to make new connections, suggests new research published in eNeuro. Cognitive decline in old age is thought to be gradual, as in Alzheimer’s disease. However, an

Genes, environment and schizophrenia: New study finds the placenta is the missing link: Placenta may also hold the key to why developmental brain disorders are more common in males

Hiding in plain sight, new research shines a spotlight on the placenta’s critical role in the nature versus nurture debate and how it confers risk for schizophrenia and likely other neurodevelopmental disorders including ADHD, autism, and Tourette syndrome. This new scientific frontier, with far-reaching implications for maternal and child health, creates the possibility that scientists

Characteristics of microorganisms most likely to cause a global pandemic

Infectious disease preparedness work focuses predominantly on an historical list of pathogens derived from biological warfare agents, political considerations, and recent outbreaks. That fails to account for the most serious agents not currently known or without historical precedent, write scholars from the Johns Hopkins Center for Health Security in a new report on the traits

Stronger alcohol policies help reduce alcohol-related crash deaths in US

Stronger alcohol policies, including those targeting both excessive drinking and driving while impaired by alcohol, reduce the likelihood of alcohol-related motor vehicle crash deaths, according to a new study from Boston Medical Center and Boston University.

Just as we abide by an external time schedule to eat, sleep, and go to work, our body is similarly dictated by internal clocks. Known as circadian rhythms, these daily cycles keep us on a regular 24-hour day and are involved in numerous aspects of our well-being. When these biological clocks fail to work as

Gut bacteria play key role in anti-seizure effects of ketogenic diet

UCLA scientists have identified specific gut bacteria that play an essential role in the anti-seizure effects of the high-fat, low-carbohydrate ketogenic diet. The study, published today in the journal Cell, is the first to establish a causal link between seizure susceptibility and the gut microbiota — the 100 trillion or so bacteria and other microbes
