At the heart of the circadian clock

(Phys.org) —Cellular processes in most organisms are regulated by an internal clock, and proteins called cryptochromes are at the core of its central oscillator. The three dimensional structures of cryptochromes from mouse ...

Tissue in trouble calls in reinforcements to restore health

Northwestern University scientists are the first to discover a cellular process used by animals when a tissue is stressed and in molecular trouble from the expression of misfolded and damaged proteins: The tissue at risk ...

Scientists peer into a cell in real time

A dream of scientists has been to visualize details of structures within our cells in real time, a breakthrough that would greatly aid in the study of their function. However, even the best of current microscopes can take ...

Quantum-assisted nano-imaging of living organism is a first

In science, many of the most interesting events occur at a scale far smaller than the unaided human eye can see. Medical researchers might realize a range of breakthroughs if they could look deep inside living biological ...

Novel insights into the evolution of protein networks

System-wide networks of proteins are indispensable for organisms. Function and evolution of these networks are among the most fascinating research questions in biology. Bioinformatician Thomas Rattei, University of Vienna, ...

Biologists produce rainbow-colored algae

What can green algae do for science if they weren't, well, green? That's the question biologists at UC San Diego sought to answer when they engineered a green alga used commonly in laboratories, Chlamydomonas reinhardtii, ...

Scientists study transient degradation of an actin regulator

Scientists at the Center for Molecular Biology of Heidelberg University have gained new insight into the process of mitosis in mammalian cells. Researchers under the direction of Prof. Dr. Frauke Melchior, in collaboration ...
