Research may point to new ways to deliver drugs into bacteria

An exhaustive look at how bacteria hold their ground and avoid getting pushed around by their environment shows how dozens of genes aid the essential job of protecting cells from popping when tensions run high.

New biosensor could monitor glucose levels in tears and sweat

Constantly tracking a person's glucose levels through their tears or sweat could be one step closer to providing people with diabetes an improved monitoring tool. Researchers report in the journal ACS Nano the development ...

Entropy production gets a system update

Nature is not homogenous. Most of the universe is complex and composed of various subsystems—self-contained systems within a larger whole. Microscopic cells and their surroundings, for example, can be divided into many ...

First artificial scaffolds for studying plant cell growth

As a baby seedling emerges from the depths of the soil, it faces a challenge: gravity's downward push. To succeed, the plant must sense the force, then push upward with an even greater force. Visible growth is proof that ...

Researchers unravel secrets of shape-shifting bacteria

Sixty years ago, Nobel Prize-winning scientist Joshua Lederberg first described a biological mystery. He showed how bacteria could lose the cell walls that define their shapes, potentially becoming less visible to the immune ...
