Introducing metallic ions within a DNA molecule will have many uses in bio- and nanotechnology

Scientists have proven, for the first time, that introducing slight chemical modifications in DNA molecules may allow to introduce metallic ions in it, keeping its double-stranded structure and molecular recognition properties (for other DNA molecules, enzymes, proteins, etc.).

Neuro chip records brain cell activity

In order to understand how the brain controls functions, such as simple reflexes or learning and memory, we must be able to record the activity of large networks and groups of neurons. Conventional methods have allowed scientists to record the activity of neurons for minutes, but a new technology, known as a bionic hybrid neuro chip, is able to record activity in animal brain cells for weeks at a much higher resolution.
