Discovery of kidney structure challenges current understanding of renal physiology - Medical Xpress


Medical Xpress
Previous studies into this microscopic structure have avoided using the physiological pressures of blood in preparing the kidney. Much like pumping up a tyre, without the correct pressure, the tiny blood vessels and tubules within the kidney structure ...

Pushing the frontiers of biology - The Hindu


The Hindu
My work in the lab comprised core molecular biology procedures such as DNA isolation and RNA isolation from blood samples of cardiac patients. I worked on Polymerase Chain Reaction (PCR), a technique to amplify the copies of a segment of DNA ...

Artificial neural networks now able to help reveal a brain's structure - Medical Xpress


Medical Xpress
Scientists from Google AI and the Max Planck Institute of Neurobiology describe a method based on artificial neural networks that is able to reconstruct entire nerve cells with all their elements and connections almost error-free from image stacks.

Structure of Memes
Belgium

The main criticism that can be raised against the memetic approach is that memes are difficult to define. What are the elements or units that make up a meme? Does a meme correspond to a complete symphony, or to a symphonic movement, a melody, a musical phrase, or even a single note?

Chromatin Structure
United States

Chromatin is the substance which becomes visible chromosomes during cell division. Its basic unit is nucleosome, composed of 146 bp DNA and eight histone proteins. The structure of chromatin is dynamically changing, at least in part, depending on the need of transcription. In the metaphase of cell division, the chromatin is condensed into the visible chromosome. At other times, the chromatin is less condensed, with some regions in a "Beads-On-
