Scientists at the Niels Bohr Institute have successfully controlled bacterial jets to carry strings of microscopic cargos, opening up new possibilities for biological tools and medical applications. The novel approach utilizes a liquid crystal to dictate bacterial movement, suppressing instabilities and enabling precise cargo transport.
Bacteria use a hopping motion to move through tight spaces in the human intestine, improving medical and environmental technologies. Researchers at Princeton University developed a new model with improved accuracy, leveraging complex geometry simulations.
The study analyzed data from nearly 3,000 gay and bisexual men in Australia who received daily HIV PrEP, revealing an association between bacterial STIs and specific risk behaviors. The findings suggest that PrEP users are at higher risk of chlamydia, gonorrhea, or syphilis diagnoses.
Bacteria can reduce liquid viscosity and make it flow frictionlessly. Researchers at the University of Bristol found that bacterial suspensions can exhibit negative viscosity, a phenomenon previously thought impossible in physics. This discovery could lead to the development of bacteria-powered machines.
Theoretical physicists analyze flocking behavior on curved surfaces, including a sphere and an hourglass-shaped figure called a catenoid. They found special sound modes that don't dissipate and flow around obstacles, with the sphere's bands centered on the equator.
Researchers found that fruit fly infections trigger a reduction in egg-laying activity and affect the octopaminergic signalling pathway. The study reveals a protective mechanism allowing fruit flies to regulate their offspring's impact on the environment during bacterial infection.
Researchers created complex reconfigurable microrobots that can be manufactured with high throughput, mimicking the behavior of bacteria to deliver drugs or perform precise operations. The robots are soft, flexible, and motor-less, using electromagnetic fields and heat to control their movement.
The Journal of Dairy Science has compiled two new collections of articles, one on stocking density for dairy cattle and the other on lactic acid bacteria. The stocking density collection includes 10 articles published between 2006 and 2015, while the lactic acid bacteria collection contains 30 articles published between 1962 and 2016.
A study presented at the American Stroke Association's International Stroke Conference 2016 found that restoring gut bacteria to a youthful age was linked to improved stroke recovery in old mice. Researchers used fecal transplants to deliver a 'young' set of bacteria to mice with induced strokes, resulting in better recovery rates.
Researchers have discovered that polymers can disrupt the way bacteria communicate with each other, leading to unexpected clustering behaviors. This finding has significant implications for the design of materials as antimicrobials, bioprocessing, and synthetic biology.
Research suggests that bacteria in the gut may control host appetites by influencing signaling pathways. The gut microbiota respond to nutrients and hormones, generating compounds that affect appetite and mood disorders. Further studies are needed to determine if gut bacteria directly influence food choice.
A MU biochemistry professor has been awarded a $5.5 million NIH MERIT Award to continue his research on bacterial behavior and molecular memory. His work could shed light on human sensory, memory, and response systems.
A new study by engineering researchers at Rensselaer Polytechnic Institute demonstrates the impact of viscoelasticity on the collective behavior of swimming microorganisms, such as H. pylori. The findings suggest that human mucus and saliva may have evolved to disrupt the ability of harmful bacteria to coordinate.
Researchers at Tel Aviv University developed a computational model that explains how bacteria move in a swarm, enabling the design of intelligent robots. Bacteria's superior survival skills come from their ability to adjust interactions with peers and utilize short-term memory.
Researchers found that human cells follow a bimodal correlated random walk pattern when moving in search of nutrients and growth factors. This discovery provides a general framework for analyzing cell movement, with potential applications in predicting the effectiveness of untested therapies.
Researchers at the University of Southern California have discovered a new bacterial behavior where Shewanella oneidensis harvests electrochemical energy and swims in response to metal presence. This finding could improve the efficiency of microbial fuel cells, producing usable energy.
Scientists have created a new approach to studying bacterial swimming, using optical traps, microfluidic chambers and fluorescence to track Escherichia coli movement. The method allows researchers to trap bacteria and modify their environment without hindering movement, providing insights into the mechanics of bacterial swimming.
A new study by Uppsala University researchers has discovered nearly half of Mediterranean gulls in southern France exhibit antibiotic resistance. The bacteria in question are capable of spreading rapidly and have broken down powerful antibiotics.
Researchers found that female mosquitoes are attracted to water containers with specific fatty acids and methyl esters from bacteria, which stimulate them to lay eggs. The study aims to use this knowledge to devise lures and traps to control yellow fever mosquito populations, preventing global diseases like dengue fever.
