Bacteria get around

Get Around 360o Hypervideo

In traditional video, the user is locked to the angle where the camera was pointing to during the capture of the video. With 360o video recording, there are no longer these boundaries, and 360o video capturing devices are becoming more common and affordable to the general public. Hypervideo stretches boundaries even further, allowing to explore the video and to navigate to related information. ...

Hitchhikers Get Around

Previous studies have shown that hitchhiking in standard GAs can cause premature convergence. In this study we show that hitchhiking also occurs in adaptive operators, specifically, selective crossover an adaptive recombination operator. We compare selective crossover with uniform crossover (a highly disruptive operator) and show that although selective crossover favours hitchhikers more than u...

Nuclear proteins get around

In This Issue In This Issue Nuclear proteins get around rotein trafficking between the cytoplasm and the nucleus has been studied extensively; but how do proteins move from one site to another within the nu-cleus? On page 615, Leung and Lamond focus on the intranuclear trafficking of the RNA-binding protein NHPX, and describe an elegant series of experiments that demonstrates the existence of m...

Senescence: Even Bacteria Get Old

Cellular senescence, even in the presence of abundant nutrients, has now been demonstrated in several microbes, including most recently the bacterium Escherichia coli, suggesting that it may be a universal adaptive response to the inevitable damage to cell constituents that accumulates with time.

Don't get around much any more.
