The key to their survival, a study reveals, is the ability to more than triple how fast they capture light energy and funnel it through to molecules that convert it into food. The finding could generate new bio-inspired designs for light-harvesting systems.
Much like motors power our cars, they also ensure that proteins get to the right place in our cells, and a wide variety of diseases - from cancer to heart problems - can result when they don't. Now scientists have evidence of more flexibility and a little crosstalk in how motors maneuver our cells' intricate roadway system.
As part of an effort to develop drought-resistant food and bioenergy crops, scientists have uncovered the genetic and metabolic mechanisms that allow certain plants to conserve water and thrive in semi-arid climates.
Scientists have developed a powerful new technique that reveals for the first time the mechanical environment that cells perceive in living tissues - their natural, unaltered three-dimensional habitat.
Researchers have developed an odor-detecting sensor made from a membrane protein found in mosquitoes called an olfactory receptor, which responds to the smell of human sweat, that they embedded in an artificial cell membrane.
Researchers have created sOPTiKO, a more efficient and enhanced inducible CRISPR genome editing platform. They describe how the freely available single-step system works in every cell in the body and at every stage of development. This new approach will aid researchers in developmental biology, tissue regeneration and cancer.
In two papers, a research team has reported the crystal structure of PHA synthase from Ralstonia eutropha, the best studied bacterium for PHA production. The research team also reported the structural basis for the detailed molecular mechanisms of PHA biosynthesis.
Researchers have discovered a way to make pinpoint changes to an enzyme-driven 'assembly line' that will enable scientists to improve or change the properties of existing antibiotics as well as create designer compounds. The work is the first to efficiently manipulate which building blocks the enzyme selects in the act of synthesizing erythromycin, an important antibiotic.
A research team has taken an important step in modelling the complexity of the human gut's bacterial communities - the microbiome - on the computer. The researchers gathered all known data on the metabolism of 773 bacterial strains - more than ever before. Working from this data, they developed a computer model for each bacterial strain.
An international research team has made a breakthrough advance by trapping an intermediate in the mechanism of enzymes called heme peroxidases and determining its structure using a beam of neutrons from the heart of a nuclear reactor.
