Viruses hijack deep-sea bacteria at hydrothermal vents
More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
Engineering team designs 'living materials'
Inspired by natural materials such as bone—a matrix of minerals and other substances, including living cells—MIT engineers have coaxed bacterial cells to produce biofilms that can incorporate nonliving ...
Structure of bacterial nanowire protein hints at secrets of conduction (w/ Video)
(Phys.org) —Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. ...
Using analog computation circuits, engineers design cells that can compute logarithms, divide and take square roots
MIT engineers have transformed bacterial cells into living calculators that can compute logarithms, divide, and take square roots, using three or fewer genetic parts. Inspired by how analog electronic circuits ...
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Cell circuits remember their history: Engineers design new synthetic biology circuits that combine memory and logic
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.
Viruses can have immune systems, new research shows
A study published today in the journal Nature reports that a viral predator of the cholera bacteria has stolen the functional immune system of bacteria and is using it against its bacterial host. The study provides the fi ...
Portable nanodevice provides rapid, accurate diagnosis of tuberculosis, other bacterial infections
A handheld diagnostic device that Massachusetts General Hospital (MGH) investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis (TB) and other important infectious ...
Editing the genome: New method allows scientists to insert multiple genes in specific locations, delete defective genes
Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes. The researchers say the technology ...
Some Earth bacteria survive and grow at extremely low pressure, may aid Mars research
(Phys.org)—University of Florida researchers have discovered for the first time that some Earth bacteria can live under the same low pressure conditions found on Mars.
The dynamic cytoskeleton in bacterial cell division
Researchers discover how microbes build a powerful antibiotic
Researchers report in the journal Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new ...
Genetically identical bacteria can behave in radically different ways
Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways.
bacterial cells split
Fractal patterns spontaneously emerge during bacterial cell growth
Scientists discover highly asymmetric and branched patterns are the result of physical forces and local instabilities; research has important implications for understanding biofilms and multicellular systems.
