Pattern formation: The paradoxical role of turbulence
The formation of self-organizing molecular patterns in cells is a critical component of many biological processes. Researchers have proposed a new theory to explain how such patterns emerge in complex natural systems.

A Matter of Dynamics
Most ion channels are very selective about the ions, which may or may not pass through them. They may be conductive for potassium ions and non-conductive for sodium ions or vice versa. However, a number of ion channels allows for the efficient passage of both kinds of ions. How do these channel proteins accomplish this?

How the insulin receptor works
As we are approaching the 100th anniversary of the discovery of insulin, a wide array of its signaling pathways has been defined. However, the initial step in insulin action, i.e. the engagement with its cell-surface receptor and the resulting conformational change, which propagates across the plasma membrane to the intracellular module, remains poorly understood.

Electric eel-inspired device reaches 110 volts
In an effort to create a power source for future implantable technologies, a team of researchers developed an electric eel-inspired device that produced 110 volts from gels filled with water, called hydrogels. Their results show potential for a soft power source to draw on a biological system's chemical energy.

Studying mitosis' structure to understand the inside of cancer cells
Cell division is an intricately choreographed ballet of proteins and molecules that divide the cell. During mitosis, microtubule-organizing centers assemble the spindle fibers that separate the copying chromosomes of DNA. While scientists are familiar with MTOCs' existence and the role they play in cell division, their actual physical structure remains poorly understood. Researchers are now trying to decipher their molecular architecture.

What makes circadian clocks tick?
Circadian clocks arose as an adaptation to dramatic swings in daylight hours and temperature caused by the Earth's rotation, but we still don't fully understand how they work. Scientists studying the circadian clock of blue-green colored cyanobacteria. The group discovered that how the proteins move hour by hour is central to cyanobacteria's circadian clock function.

Ras protein's role in spreading cancer
Protein systems make up the complex signaling pathways that control whether a cell divides or, in some cases, metastasizes. Ras proteins have long been the focus of cancer research because of their role as 'on/off switch' signaling pathways that control cell division and failure to die like healthy cells do. Now, a team of researchers has been able to study precisely how Ras proteins interact with cell membrane surfaces.

Scientists shed light on biological roots of individuality
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
