New technique reveals a role for histones in cell division

(Phys.org) —Proteins known as histones give structure to DNA, which coils around them like string on spools. But as is so often the case in biology, it turns out there is more to these structures than meets the eye. Scientists ...

How bacteria battle fluoride

He's not a dentist, but Christopher Miller is focused on fluoride. Two studies from his Brandeis University lab provide new insights into the mechanisms that allow bacteria to resist fluoride toxicity, information that could ...

Deploying exosomes to win a battle of the sexes

There are many biological tools that help animals ensure reproductive success. A new study in The Journal of Cell Biology provides further detail into how one such mechanism enables male fruit flies to improve their odds ...

An embryonic cell's fate is sealed by the speed of a signal

When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has ...

Key adjustment enables parasite shape-shifting

Crafty parasites frequently undergo dramatic shape changes during their life cycles that enable them to adapt to different living conditions and thrive. But these transformations might not be as difficult as they appear, ...

Genetically driven gut feelings help female flies choose a mate

Even among flies, mating is a complicated ritual. Their elaborate courtship dance combines multiple motor skills with advanced sensory cues. Remarkably this behavior is entirely innate. Now, researchers at Rockefeller University ...
