EPFL researchers have characterized a mechanism that allows bacteria to direct their movement in response to the mechanical properties of the surfaces the microbes move on -- a finding that could help fight certain pathogens.
Researchers at Cornell have developed a way to analyze how individual immune cells react to the bacteria that cause tuberculosis. It could pave the way for new vaccine strategies and provide insights into fighting other infectious diseases.
The chequered history of the Cambro-Ordovician Alum Shale in northern Europe offers insights into oil and gas formation and traces of life on Mars.
Some antibiotics appear to be effective against a form of skin cancer known as melanoma. Researchers at KU Leuven, Belgium, examined the effect of these antibiotics on patient-derived tumours in mice. Their findings were published in the Journal of Experimental Medicine.
In a new study, researchers have uncovered how cytolysins from Enterococcus faecalis destroys bacterial and mammalian cells.
Natto, a fermented soybean dish often served for breakfast in Japan, originated at the turn of the last millennium but may hold an answer to a modern problem: COVID-19, according to a new study based on cell cultures.
The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists, including David Fike at Washington University in St. Louis.
Decreasing bacterial acidity could help reduce antimicrobial resistance by eliminating bacteria that can survive being treated with antibiotics.
Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.
What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce. One ingenious solution to this challenge is reported this week in Proceedings of the National Academy of Sciences.
