A little place for my stuff: How big bacteria can grow depends on how much fat they can make

Just as people endlessly calculate how to upsize or downsize, bacteria continually adjust their volume (their stuff) to fit inside their membrane (their space). But what limits their expansion? The answer will surprise you. …

Pulling the tablecloth out from under essential metabolism

Most organisms share the biosynthetic pathways for making crucial nutrients because it is is dangerous to tinker with them. But now a collaborative team of scientists has caught plants in the process of altering where and how cells make an essential amino acid. …

Cloning thousands of genes for massive protein libraries

Discovering the function of a gene requires cloning a DNA sequence and expressing it. Until now, this was performed on a one-gene-at-a-time basis, causing a bottleneck. Scientists have invented a technology to clone thousands of genes simultaneously and create massive libraries of proteins from DNA samples, potentially ushering in a new era of functional genomics. …

Peanut family secret for making chemical building blocks revealed

The peanut and its kin — legumes — have not one, but two ways to make the amino acid tyrosine. That might seem small, but why this plant family has a unique way to make such an important chemical building block is a mystery that extends back to the 1960s. …

Vinegar: A cheap and simple way to help plants fight drought

Researchers have discovered a new, yet simple, way to increase drought tolerance in a wide range of plants. The study reports a newly discovered biological pathway that is activated in times of drought. By working out the details of this pathway, scientists were able to induce greater tolerance for drought-like conditions simply by growing plants in vinegar. …

New mechanism for bacterial division discovered in some bacteria

Scientists show how some pathogenic bacteria — such as the mycobacteria that cause tuberculosis — use a previously unknown mechanism to coordinate their division. The discovery could help develop new ways to fight them.

Microbes from ships may help distinguish one port from another

Much the way every person has a unique microbial cloud around them, ships might also carry distinct microbial signatures. The key is testing the right waters — the bilge water from the bottoms of ships.
