Researchers unravel mechanisms that control cell size

Working with bacteria, a multidisciplinary team at the University of California San Diego has provided new insight into a longstanding question in science: What are the underlying mechanisms that control the size of cells?

Biofilm reactor promises to cut production costs on vitamin K

In an innovative study that promises to reduce production costs for the most potent form of vitamin K—Menaquinone-7, Penn State researchers have developed a novel method to enhance the fermentation process that creates ...

Surprise finding points to DNA's role in shaping cells

As a basic unit of life, the cell is one of the most carefully studied components of all living organisms. Yet details on basic processes such as how cells are shaped have remained a mystery. Working at the intersection of ...

Bacteria recruit other species with long-range electrical signals

Biologists at UC San Diego who recently found that bacteria resolve social conflicts within their communities and communicate with one another like neurons in the brain have discovered another human-like trait in these apparently ...

Tiny 'racetracks' show how bacteria get organized

As the world prepares to watch the Summer Olympics' track and field events in Rio, it will come as no surprise that the runners in each race travel in the same direction around the track. But new research shows that if those ...

Bacteria use DNA replication to time key decision

In spore-forming bacteria, chromosomal locations of genes can couple the DNA replication cycle to critical, once-in-a-lifetime decisions about whether to reproduce or form spores. The new finding by Rice University bioengineers ...

Bacteria are wishing you a Merry Xmas

A bacterium has been used to wish people a Merry Xmas. Grown by Dr Munehiro Asally, an Assistant Professor at the University of Warwick, the letters used to spell MERRY XMAS are made of Bacillus subtilis, a non-pathogenic ...
