How gene expression noise shapes cell fate

Essential genes are often expressed with high variability during the development of cells. Scientists call this phenomenon "biological noise" and suspect that it is also decisive for the fate of cells, i.e. the developmental ...

A protein that pulls the brake on nerve growth

During embryonic development, nerve cells form long, thin extensions that wire up the complex network of the brain. Scientists from the German Center for Neurodegenerative Diseases (DZNE) in Bonn have now identified a protein ...

Scientists discover new process shaping red blood cell development

Red blood cells give us life. They ferry oxygen throughout our bodies. Breakdowns in red blood cell development can be life-threatening, but scientists still have much to learn about the molecular processes that ensure these ...

An ultrafast glimpse of the photochemistry of the atmosphere

Our lives are governed by submicroscopic processes in the nanocosmos. Indeed many natural phenomena begin with a minuscule shift in the states of atoms or molecules, triggered by radiation. One such process has now been elucidated ...

Better chemistry through tiny antennae

A research team at The University of Tokyo has introduced a powerful method for actively breaking chemical bonds using excitations in tiny antennae created by infrared lasers. This process may have applications throughout ...

Rapid evolution: New findings on its molecular mechanisms

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed that geographical barriers ...

Using lasers to visualize molecular mysteries in our atmosphere

Invisible to the human eye, molecular interactions between gases and liquids underpin much of our lives, including the absorption of oxygen molecules into our lungs, many industrial processes and the conversion of organic ...
