Novel high-speed microscope successfully records neural activities

Our brain contains tens of billions of nerve cells (neurons) which constantly communicate with each other by sending chemical and electrical flashes, each lasting a short one millisecond (0.001 sec). In every millisecond, these billions of swift-flying flashes altogether traveling in a giant star-map in the brain that lights up a tortuous glittering pattern.

Research provides new insights into building blocks of gum disease

Porphyromonas gingivalis is a major bacterial pathogen which leads to periodontitis also known as gum disease. In Japan, 80% of adults aged 35 and over suffer from this disease. What's more, P. gingivalis has also been linked to rheumatoid arthritis, cardiovascular disease, pancreatic cancer, and even Alzheimer's disease.

Memory cells that help to interpret new situations identified

Imagine you are meeting a friend for dinner at a new restaurant. You may try dishes you haven't had before, and your surroundings will be completely new to you. However, your brain knows that you have had similar experiences -- perusing a menu, ordering appetizers, and splurging on dessert are all things that you have probably done when dining out.

Regulating ion flow using a ball-and-chain mechanism

Ion channels that permit potassium and sodium ions to move in and out of cells are essential for the function of the brain and heart, and also for neuronal “firing” in the central nervous system.

Researchers uncover a surprising property of blood stem cells

A Franco-German research team led by Prof. Michael Sieweke, from the Center for Regenerative Therapies TU Dresden and the Center of Immunology of Marseille Luminy, today uncovered a surprising property of blood stem cells: not only do they ensure the continuous renewal of blood cells and contribute to the immune response triggered by an infection, but they can also remember previous infectious encounters to drive a more rapid and more efficient immune response in the future.
