The Adventurous Journey of a Cancer Cell

By Sunaina Rao
The long tiring journey of a cancer cell from its site of origin to a distant metastatic organ.

According to results of a new study published in the journal Nature, there has been about 25 to 40% under-estimation of human contribution to methane in our atmosphere. Methane is one of the most potent greenhouse gases in our atmosphere, even more potent than CO2. Kamal J on Unsplash.

Naturally beautiful patterns emerged when two species of bacteria were cultured together.

On the left - A fibrotic tissue which favours increased colonization and outgrowth of metastasising cells. On the right - A less fibrotic tissue, which does not favour as much persistence and colonization of metastasising cells (red - blood vessels; blue - metastasising cells; brown - collagen). © Sunaina Rao.

Observing Chemical Reactions in Ultra-Slow Motion

By Devadas Vivek
At ultra-low temperatures, molecules have so little energy that, in effect, their reactivity is slowed down.

Gene Regulating Blood Stem Cells' Maintenance Identified

By Devadas Vivek
This gene called MLLT3 regulated the production of more than 800 proteins, many of which are essential for the maintenance of blood stem cells.

The Hustle Inside a Cell’s Nucleus

By Sunaina Rao
The nucleus really is a jungle of busy, hustling biomolecules and here I represent a minuscule of what really goes on in there.

In the normoxic cells, oxygen helps hydroxylate the proline residues in HIF1 α (dark blue), which then interacts with VHL (light blue), thereby leading to the proteolysis of  HIF1 α. Whereas in hypoxic cells, the  HIF1 α remains intact and hence enters the nucleus and brings about transcription. © Sunaina Rao.
