A new genomic approach provides a glimpse into the diverse bacterial ecosystem on the International Space Station.
A new study has shown that restoring environments to include a wider range of species can promote 'good' bacteria over 'bad' -- with potential benefits for human health.
A new study based on a mostly forgotten guide to medicinal plants, 'Resources of the Southern Fields and Forests,' focuses on three of the plants and shows they inhibit bacteria associated with wound infections.
A team from Harvard University, Marine Biological Laboratory, and collaborators show how the rod-shaped bacteria Bacillus subtilis maintains its precise diameter while growing end to end.
Scientists from the University of Adelaide's Research Centre for Infectious Diseases have developed a single vaccination approach to simultaneously combat influenza and pneumococcal infections, the world's most deadly respiratory diseases.
It's not exactly the set of TV's 'American Ninja Warrior,' but a tiny obstacle course for bacteria has shown researchers how E. coli changes its behavior to rapidly clear obstructions to food. The work by scientists at Carnegie Mellon University, the University of Pittsburgh and the Salk Institute for Biological Studies holds implications for not only biology and medicine, but also robotic search-and-rescue tactics.
Prof. FENG Yingang and his colleagues from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences recently revealed the structural and functional mechanism of the SigI/RsgI factors from C. thermocellum.
In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks. Addressing the problem in Frontiers in Earth Science, Swedish scientists have begun compiling evidence of fossilized microbes in underexplored igneous rock environments on Earth, to help guide where to search for a Martian fossil record - and what to look for.
A multidisciplinary team has provided new insight into underlying mechanisms controlling the precise size of cells. The researchers found that 'the adder,' a function that guides cells to grow by a fixed size from birth to division, is controlled by specific proteins that accumulate to a threshold.
Researchers have mapped the molecular structure and dynamics of an aggressive protein modification that spurs on Alzheimer's disease. A new study in the Proceedings of the National Academy of Sciences offers greater understanding of the microscopic, toxic protein fragments, called beta amyloids (Aβ), that cause rapid acceleration of Alzheimer's disease.
