Oxytocin, the hormone that induce feelings of love and well-being within us, are found to reverse some of the damage caused by amyloid plaques in the learning and memory center of the brain in an animal model of Alzheimer’s.

False color scanning electron micrograph of meningococci (orange) adherent to human host cells (green). Credit: Alexandra Schubert-Unkmeir / University of Wuerzburg Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of […]

Researchers from the RIKEN Center for Advanced Photonics and collaborators have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing the cells. This finding implies that terahertz radiation, which was long considered impractical to use, may have applications in manipulating cell functions for the […]

DNA may not be life’s instruction book, but just a jumbled list of ingredients. University of Maryland researcher develops potentially revolutionary framework for heredity and evolution in which inheritable information is stored outside the genome. The common view of heredity is that all information passed down from one generation to […]

Discovery draws surprising parallels between low-level organisms and sophisticated neurons; lays the groundwork for memory-capable biological systems. Biologists studying collectives of bacteria, or “biofilms,” have discovered that these so-called simple organisms feature a robust capacity for memory. Working in the laboratory of University of California San Diego Professor Gürol Süel, […]

This image shows a fold (shape) that may have been one of the earliest proteins in the evolution of metabolism. Credit: Vikas Nanda/Rutgers University Rutgers researchers retraced the evolution of enzymes over billions of years. Rutgers researchers have discovered the origins of the protein structures responsible for metabolism: simple molecules […]

Damage (red devils) like drying out, harsh chemicals or heat normally causes proteins to become unstable and lose their proper shape and function (left side, orange). Researchers at the University of Tokyo have characterized Hero proteins (pink, purple, green), long, flexible proteins that protect other proteins (right side, orange). Credit: […]

Immediately after a sperm fertilizes an egg, the SPRK1 enzyme leads the first step in untangling a sperm’s genome, kicking out special packing proteins called protamines, which opens up the paternal DNA and allows for major reorganization — all in a matter of hours.

Unique hydrogenation research led by CCNY’s Mahesh Lakshman is the inside cover feature in the journal Advanced Synthesis and Catalysis. Credit: Advanced Synthesis and Catalysis Chemists Develop Safer Hydrogenation Processes Safe and environmentally-friendly hydrogen gas on-demand could be on the horizon following a new “hydrogenation” chemical process in development at […]
