Day in and day out, in our bodies, the DNA in cells is damaged for a variety of reasons, and thus intercellular DNA-repair systems are fundamental to the maintenance of life. Now scientists from the UNC School of Medicine ...
Researchers have uncovered molecular details of how pathogenic bacteria fight back against the human immune response to infection.
A European team is investigating the role of the bacterial cell wall and the cytoskeleton in mediating cell shape. Results are expected to have broader implications for cell biology.
Food poisoning caused by Bacillus cereus can lead to diarrhea which is probably caused by a 3-component toxin which is produced by this bacteria strain and which perforates and kills cells.
Vibrio cholerae, the scourge of nations lacking clean water. Pseudomonas aeruginosa, the microbe that plagues people with cystic fibrosis. Acinetobacter species, opportunistic organisms that can infect vulnerable people. ...
(PhysOrg.com) -- Using bacteria to generate energy is a signifiant step closer following a breakthrough discovery by scientists from the School of Biological Sciences at the University of East Anglia.
Cell circuits remember their history: Engineers design new synthetic biology circuits that combine memory and logic
MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of generations.
The theory of evolution suggests that present-day organisms evolved from earlier life forms.
Scientists are planning for a future in which superbugs gain the upper hand against our current arsenal of antibiotics. One emerging class of drug candidates, called AMLPs (antimicrobial lipopeptides), shows promise, and ...
A study from Indiana University has found evidence that extremely small changes in how atoms move in bacterial proteins can play a big role in how these microorganisms function and evolve.
