Researchers identified a gene that actively causes a decline in food-seeking behavior after reproduction, potentially benefiting the population by reducing competition for resources. This discovery challenges traditional views on aging and offers new insights into programmed mechanisms driving age-related decline.
Scientists from Japan developed a theoretical framework that explains how collective cells can perform complex tasks. The key is distributed information processing and reinforcement learning in the environment.
A team of Japanese researchers has identified shootin1b as a protein that promotes cell migration in glioblastoma, the most common and difficult-to-treat brain tumor. By suppressing abnormal activity of shootin1b, the study suggests a potential target for preventing glioblastoma spread.
Researchers at IBEC created an artificial cell that migrates towards specific substances like living cells do. The study demonstrates how microscopic bubbles can be programmed to follow chemical trails and explores the core principles behind chemotaxis.
Scientists have developed a simple test that induces chemotactic motility in microbes, which could be a strong indicator of life. The test uses L-serine to attract microorganisms and has the potential to detect life on Mars and beyond.
A team of researchers at UC Davis Health discovered a novel bioelectrical mechanism that allows Salmonella bacteria to navigate the gut lining and find vulnerable entry points. The study found that Salmonella bacteria detect electric signals in FAE, which helps them move towards openings in the gut where they can enter.
A team from the University of Tsukuba has discovered that the enzyme ELOVL6 plays a significant role in the development of acute myeloid leukemia, a type of blood cancer. The study found that high levels of ELOVL6 are linked to shorter survival rates for leukemia patients.
Scientists from the Institute of Industrial Science have developed a theoretical model for optimal search strategy in biological systems, which may help design new drones or nanobots. The model uses stochastic optimal control theory to analyze chemotaxis, a process of attraction to chemical gradients.
Researchers at Texas A&M University found that bacteria adjust their flagella to changes in fluid viscosity, enabling navigation and colonization. This adaptation, similar to proprioceptive adaptation, helps bacteria form swarms and colonize diverse environments.
A recent study has identified a nematode attractant in flax seeds, which can be used to develop sustainable and environmentally-friendly agriculture methods. The attractant, consisting of cell wall polysaccharides, is found to contain L-galactose sidechains that are critical for nematode attraction.
A new device has been developed to perform high-throughput 3D chemotactic assays, revealing diversity and complexity in the chemotactic regulation of neuronal development by various guidance molecules. The platform uses a hydrogel-based microfluidic system to test hundreds of suspended microscale hydrogel cylinders with distinct gradie...
Scientists used fluorescent tagging to track movement of two enzymes in glycolytic pathway, revealing that aldolase chemotaxed up the reactant gradient produced by the functioning of the first three enzymes. This suggests a possible role for chemotaxis in enzyme cluster assembly, such as metabolons.
A worldwide competition of engineered cells through microfluidic mazes revealed that neutrophil-like cells must balance speed against chemotactic accuracy. An adapted version of the amoeba Dicty with increased activity of a particular protein, Ric8, emerged as the most successful strategy.
Researchers at Indiana University Bloomington found that even when ovary extracts are diluted 100,000 times, some sperm cells still respond to the scent. This discovery may help scientists understand problems with human conception and develop a diagnostic tool for male infertility.
