Beautiful bacteria.

The images above are some examples of rotex fractal growth found in colonies of Bacillus subtilis. The varying branching patterns are caused by changes in the environmental conditions of the bacteria as they grow.

Fuckin’ nature!

fuckyeahmolecularbiology: Sensory axons (long, slender nerve fibres) covering the tail of a 3-day-old larval zebrafish. This is a “Brainbow“ image made using confocal microscopy. In the Brainbow technique, cells randomly choose combinations of red, yellow, and cyan fluorescent proteins, so that they each glow a particular color. This provides a way to distinguish neighbouring cells of the nervous system and follow their individual pathways.

fuckyeahmolecularbiology: T cells are white blood cells that play a crucial role in cell-mediated immunity. They can be divided into several categories - notably helper, cytotoxic, memory, regulatory, and natural killer (NK) - and their primary role within the immune system is to search out and destroy both invading pathogens and abnormal cells. Helper T cells also help to regulate the immune response. The image above features a cytotoxic T cell, which destroys abnormal cells (most notably, virally infected cells and tumour cells) and are also implicated in organ transplant rejection. Dendritic cells, pictured cyan blue in the photo, constitutively express high levels of both class I and class II MCH molecules - the type of receptor that cytotoxic T cells recognise - making them extraordinary potent activators capable of stimulating even “naïve” T cells that have never encountered an antigen.
