Researchers found magnetotactic bacteria living on a hydrothermal vent chimney at 2,787 meters below the ocean's surface. The discovery provides clues to the early diversification of bacteria and offers insights into the environment that may support extraterrestrial life.
A team of scientists has discovered a novel magnetotactic bacterium that forms intracellular amorphous silica globules. This finding suggests a previously unobserved influence on the global silicon cycle during early Earth history, expanding our knowledge of prokaryotic biosilicification.
A multidisciplinary research group uses magnetotactic bacteria to create nanomagnetic structures, which can be steered through the human body via external magnetic fields. They have developed a new method to measure the magnetic properties of individual nanomagnets in biological entities, enabling precise control over these structures.
Researchers have identified specific skin microbiome bacteria and their pathways as contributing to ageing skin. The study, published in PLOS ONE, used a novel approach to chart host-microbe co-metabolism in skin aging.
LETI researchers identified the main properties of magnetotactic bacteria and described their application in medicine. They will help create theranostic agents in neurooncology and cardioprotection by using magnetosomes to transport drugs directly to malignant tumors.
Researchers propose a hypothesis that animals use magnetotactic bacteria in a symbiotic relationship to gain a magnetic sense, which could improve human navigation and inform ecological research. The study found evidence of magnetotactic bacteria associated with various animal species, including sea turtles, birds, and mammals.
The study found that the magnetic field orientation of magnetosomes is slightly tilted, deviating from the chain direction. This tilt may explain the helical shape of magnetosome chains, a crucial aspect of magnetotactic bacteria's internal compass construction.
Researchers have developed a simple mechanism to control the swimming direction of magnetotactic bacteria, which can provide insight into the earth's sedimentary layers and potentially be used as indicators of climate change. The new tool uses a rotating permanent magnet to generate a controlled magnetic field.
Researchers at The Ohio State University have developed a method to purify and enrich magnetotactic bacteria, which can produce magnetic nanocrystals. These bacteria are found in aquatic environments worldwide and possess unique properties that allow them to align with the Earth's magnetic field.
Scientists have sequenced the genome of magnetotactic bacteria, revealing common gene clusters and a key to unlocking new technologies. The study could accelerate biotechnology and nanotechnology research with applications in electromagnetic tapes, drug delivery, magnetic resonance imaging, and cell separation.
Researchers discovered that magnetotaxis, a phenomenon where bacteria align like tiny swimming compass needles, helps them detect lower oxygen concentrations more efficiently. This subtle advantage allows the bacteria to thrive in environments with limited oxygen, making their magnetic properties beneficial in nature.
Researchers found barbell-shaped bacteria in a marine pond that swim toward geomagnetic south when oxygen levels are high, contradicting the accepted model of magnetotaxis. The discovery suggests new models are needed to explain how these bacteria behave in their environment.
