SUTD researchers have developed a technology that tracks the impact of pollutants on aquatic microorganisms, measuring their swimming speed and movement within minutes. This method allows for rapid assessment of water quality and drinkability, making it suitable for underdeveloped regions without specialized equipment or chemicals.
Paramecium uses a complex system to determine mating types, allowing for genetic variation and reproduction. The mechanism involves programmed genome rearrangements and small RNAs that eliminate unnecessary DNA sequences.
Researchers found that Paramecium, a single-celled organism, uses sex as a way to cope with stress and increase survival rates. The study suggests a mechanistic link between sex and the stress response, where increased expression of heat shock proteins during sexual reproduction provides protection from stressors.
Researchers identified five groups of PiggyBac transposases working together with PiggyMac to accurately delete specific pieces of DNA. This discovery sheds light on the mechanism of gene removal and its role in species development and evolution.
A new study from the University of Nebraska-Lincoln found that predators can catalyze the rise and fall of chlorovirus populations by exposing algae to viruses. The research suggests that the structure of food webs in an ecosystem may influence viral propagation, with a potential game-changer for virology.
Scientists have found a way to control the sensitivity of coiled protein polymers called R bodies, making them unfurl at higher or lower pH levels. The proteins can burst open 60% of bacterial cells in acidic conditions, offering potential use in delivering molecules inside living systems and targeting biotechnology applications.
Researchers discovered single-cell organisms can somersault and bend their bodies to navigate confined spaces, exhibiting unique behaviors such as meandering wanderings and ballistic swimming traits. This finding has significant implications for the study of microfluidics and its applications in various engineering and scientific fields.
Research by Brown University scientists found that paramecia's buoyancy affects their ability to navigate flat surfaces. Under normal conditions, they use their sensory systems to turn and swim away, but with altered buoyancy, they get stuck at an angle, unable to complete the turn.
Researchers at Brown University discovered that cilia in single-celled organisms like paramecium have distinct motor behaviors for swimming and nutrient uptake. The findings provide insight into the molecular mechanisms behind these diverse functions.
Ingmar Riedel-Kruse's lab group developed video games where players influence the behavior of living microorganisms in real-time. These biotic games aim to educate people about basic biological processes and promote interest in biology, with potential applications in crowd-sourced research.
Physicists at Brown University used magnetic fields to manipulate gravity and study paramecium behavior in water. The study found that by altering the gravitational force, paramecia swam differently under high gravity, zero gravity, or even reverse gravity conditions.
