Disrupted movement makes macrophages more lethal to tuberculosis bacteria
Macrophages—the front line of our immune system—protect us from infections. But in the case of the tuberculosis bacteria, this often goes wrong. The group of Annemarie Meijer from the Leiden Institute of Biology has now discovered that macrophage.....»»
Researchers discover two vesicle fusion mechanisms while studying vesicle movement in living cells
Cells intake substances from the outside world by encapsulating them in vesicles called endosomes, which are subsequently transported throughout the cell. During the transport process, vesicles fuse with other intracellular organelles. However, obser.....»»
Protesters close Chicago Apple Store over Palestinian employee firing
A small group of demonstrators disrupted the Lincoln Park Apple Store in Chicago on Saturday to protest Apple's use of labor in Africa and its disciplining of at least one employee wearing pro-Palestinian clothing items.The protest, which took place.....»»
Research introduces digital games along with multimedia debriefing to address cyberbullying
The global COVID-19 pandemic caused much suffering and tragedy and continues to do so. One aspect of our everyday lives that was massively disrupted was education. Conventional classroom teaching methods had to be digitized urgently during lockdowns.....»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»
Beyond TSMC, Apple"s supply chain will be disrupted by the Taiwan earthquake
The Taiwan earthquake will cause issues for a number of Apple suppliers beyond TSMC, but the supply chain's impact probably won't be severe long-term, thanks to globalization. Here are some of Apple's suppliers that the company will need to keep an e.....»»
Study describes zinc oxide nanoparticle strategy for inactivation of multidrug-resistant bacteria
An article published in the Journal of Environmental Chemical Engineering describes a possible strategy for promoting selective inhibition of multidrug-resistant bacteria, which are increasingly abundant owing to the indiscriminate use of antibiotics.....»»
Report provides up-close look at pro-democracy conservatives
Pro-democracy conservatives appreciate diverse political ideas, value journalism, and trust institutions including elections, according to a new report that defines this quiet but potentially powerful movement......»»
Myrtle rust is lethal to Australian plants. Could citizen scientists help track its spread?
Every weekend, thousands of citizen scientists head into the great outdoors. If they see an unusual animal, plant or fungi, they take a photo and upload it......»»
Wound treatment hydrogel infused with amino acid kills bacteria naturally and promotes cell growth
Hydrogels are popular for use in skin ailments and tissue engineering. These polymer-based biocompatible materials are useful for their abilities to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture.....»»
Researchers explain how green algae and bacteria together contribute to climate protection
A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the to.....»»
New antibiotic class effective against multidrug-resistant bacteria discovered
Scientists at Uppsala University have discovered a new class of antibiotics with potent activity against multi-drug resistant bacteria, and have shown that it cures bloodstream infections in mice. The new antibiotic class is described in an article i.....»»
Ancient Adélie penguin DNA reveals that small repeats persist for hundreds of millions of years
Microsatellites are valuable tools for studying inheritance, genetic diversity, and population dynamics across a wide range of organisms including bacteria, plants, animals, and fungi. These short, repeating sequence motifs are a common feature of bo.....»»
Scientists Are Unlocking the Secrets of Your ‘Little Brain’
The cerebellum is responsible for far more than coordinating movement. New techniques reveal that it is, in fact, a hub of sensory and emotional processing in the brain......»»
Q&A: Can genetic genealogy restore family narratives disrupted by the transatlantic slave trade?
Some political figures seek to remove references to slavery from the study of American history, adding to the vast knowledge gaps that stem from the transatlantic slave trade. To better understand these histories, scholars and individuals are turning.....»»
Study identifies protein responsible for gas vesicle clustering in bacteria
Gas vesicles are hollow structures made of protein found in the cells of certain microorganisms, and researchers at Rice University believe they can be programmed for use in biomedical applications......»»
Q&A: Archaeologist"s fieldwork finds movement of crops, animals played a key role in domestication
Archaeologist Xinyi Liu at Washington University in St. Louis teamed up with Martin Jones of the University of Cambridge to write a new paper for the Proceedings of the National Academy of Sciences that explains how recent research is connecting the.....»»
Tuberculosis vaccine may enable elimination of the disease in cattle by reducing its spread
Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds. The research, led by the University of Cambridge and Penn State University, improves prospects for the elimination and c.....»»
Study finds wild nematode worms learn to avoid harmful bacteria—and their offspring inherit this knowledge
The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations. A team led by Coleen Murphy at Princeton University report t.....»»
Sniffing out bacteria: Team develops a novel approach for rapid bacterial species identification
Do you ever wonder how researchers identify bacterial infections? Traditionally, they collect samples from the infected site, grow the bacteria in a lab, and analyze them using a method called MALDI-ToF-MS. Although accurate, this method is time-cons.....»»
Biologists determine bacteria sense damage to relatives
Carnegie Mellon University biologists have discovered that Vibrio cholerae, the bacteria behind the cholera disease, can sense when its relatives die. Bacterial cell death is often accompanied by lysis, where the cell explodes, releasing internal cel.....»»
