Researchers have identified a possible new treatment for gonorrhea, using a peptide that thwarts the infection-causing bacterium by interfering with an enzyme the microbe needs to respirate.
Engineers at Washington University in St. Louis and Princeton University developed a new way to dive into the cell's tiniest and most important components. What they found inside membraneless organelles surprised them, and could lead to better understanding of fatal diseases including cancer, Huntington's and ALS.
Individuals who do not produce enough iron are anemic, and often experience fatigue. One common remedy is for physicians to prescribe an iron infusion to their anemic patients. This makes sense, but can lead to unexpected consequences like increasing the risk of food poisons such as Salmonella. These types of poisons depend on abundant access to iron. Physicians should be attuned to this dynamic when determining the strength of iron infusions for their anemic patients.
EPFL scientists show how some pathogenic bacteria -- such as the mycobacteria that cause tuberculosis -- use a previously unknown mechanism to coordinate their division. The discovery could help develop new ways to fight them.
The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 is one of the most studied spills in history, yet scientists haven't agreed on the role of microbes in eating up the oil. Now a research team at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has identified all of the principal oil-degrading bacteria as well as their mechanisms for chewing up the many different components that make up the released crude oil.
Toxins produced by three different species of fungus growing indoors on wallpaper may become aerosolized, and easily inhaled. The findings, which likely have implications for 'sick building syndrome,' were published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
An adult mouse model reveals that changes in lattice-like structures in the brain known as perineuronal nets are necessary to 'capture' an auditory fear association and 'haul' it in as a longer-term memory.
New research results from Aarhus University and New York University show how active transport of potassium can be achieved by a membrane protein complex that has roots in both ion pump and ion channel super-families. The results, which have just been published in Nature, shed new light on what define channels and pumps.
A team of researchers from the University of Würzburg has discovered an interesting enzyme in the pathogens responsible for African sleeping sickness: It could be a promising target for drugs.
Biofilms are slimy, glue-like membranes that are produced by microbes in order to colonize surfaces. They protect microbes from the body's immune system and increase their resistance to antibiotics. Biofilms represent one of the biggest threats to patients in hospital settings. But there is good news -- Canadian scientists have developed a novel enzyme technology that prevents the formation of biofilms and can also break them down.
