Ancient protein offers clues to killer condition

... in smooth muscle by adhering to form a filament, which grabs hold of a neighbouring filament, and relaxes by letting go. When the muscle is in a relaxed state, myosin molecule folds itself up into a compact structure. This folded structure allows the smooth muscles to adjust to being different ...

The authors hypothesize that the elevated lead levels stem from the later industrialization and more relaxed pollution regulations in Asian countries compared to North America and Europe. Title: Ice core record of rising lead pollution in the North ...

In nature -- and maybe the corner office -- scientists find that generalists can thrive

... study, started with an established mathematical model in current biology literature that leads to complete division of labor. In their design, they relaxed two assumptions, making inefficiency less costly and allowing generalists to make mistakes. The researchers determined the worth of generalists to ...

Media highlights in the January issues of Biophysical Journal

"This contributes to a growing literature on how animal behavior changes under relaxed selection pressures," said Jessica Yorzinski, a graduate student in animal behavior at UC Davis, who authored the study with Thomas Ziegler of the ...

Bioclocks work by controlling chromosome coiling

... the simplest organism known to possess a biological clock. The chromosomes in cyanobacteria are organized in circular molecules of DNA. In their relaxed state, they form a single loop. But, within the cell, they are usually supercoiled into a series of small helical loops. There are even two families ...

Life's origins were easier than was thought

... It is worth remembering that tRNAs (essential molecules for the synthesis of proteins) are approximately 70 bases long. The discovery has greatly relaxed the conditions necessary for the first living organisms to develop. "This quantity of genes would be enough for a simple organism to have enough ...
