Current treatments for tuberculosis (TB) are very effective in controlling TB infection caused by Mycobacterium tuberculosis (Mtb). They don’t, however, always prevent reinfection. Why this happens is one of the long-standing questions in TB research. So why are our bodies unable to generate permanent immunity to TB, – the leading infectious disease killer worldwide? A…

Imagine smart materials that can morph from being stiff as wood to as soft as a sponge – and also change shape. Rutgers University-New Brunswick engineers have created flexible, lightweight materials…

The proteins – the transcription factors SIX1 and SIX2 – activate cellular pathways required for fetal development and later switch…
Rockville, Md. (March 22, 2019)–A new article explores the pathophysiological factors that link sleep disturbances and Alzheimer’s disease. Better understanding of this connection may lead to potential diagnostics and therapeutics for Alzheimer’s disease and other neurodegenerative diseases and dementia. The article is published ahead of print in the Journal of Neurophysiology (JNP). Alzheimer’s research has…
