Biological safety lock for genetically modified organisms
The creation of genetically modified and entirely synthetic organisms continues to generate excitement as well as worry.
Researchers engineer bacterium to hunt down and kill pathogens
Bacteria develop restraint for survival in a rock-paper-scissors community
It is a common perception that bigger, stronger, faster organisms have a distinct advantage for long-term survival when competing with other organisms in a given community.
Bacteria can grow under extreme gravity: study
Slower evolving bacteria win in the end
High-speed filter uses electrified nanostructures to purify water at low cost
(PhysOrg.com) -- By dipping plain cotton cloth in a high-tech broth full of silver nanowires and carbon nanotubes, Stanford researchers have developed a new high-speed, low-cost filter that could easily be ...
Scientists Explain Why Computers Crash But We Don't
(PhysOrg.com) -- Nature and software engineers face similar design challenges in creating control systems. The different solutions they employ help explain why living organisms tend to malfunction less than ...
Scientists crash test DNA's replication machinery
(PhysOrg.com) -- Important molecular machines routinely crash into one another while plying their trades on DNA. New research shows that the enzymes that copy DNA before cell division, called replisomes, are the kings of ...
Researchers find new ways to understand bacteria's 'thinking'
It's not thinking in the way humans, dogs or even birds think, but new findings from researchers at the University of Tennessee, Knoxville, show that bacteria are more capable of complex decision-making than previously known.
Research could lead to new non-antibiotic drugs to counter hospital infections
Lack of an adequate amount of the mineral phosphate can turn a common bacterium into a killer, according to research to be published in the April 14, 2009, issue of the Proceedings of the National Academies of ...
Bacterial adaptive defenses could aid in disease prevention
Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity.
Sweet smell of success: Researchers boost methyl ketone production in E. coli
Two years ago, researchers at the U.S. Department of Energy's Joint BioEnergy Institute (JBEI) engineered Escherichia coli (E. coli) bacteria to convert glucose into significant quantities of methyl ketone ...
Engineered for tolerance, bacteria pump out higher quantity of renewable gasoline
An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, published in mBio, the online open-access journa ...
New method tracks metal-ion movement in periplasmic proteins
Copper is an essential nutrient for most organisms. However, it is toxic at high concentrations and, in fact, is used by macrophages to kill invading microbes. To counter the lethal effects of both environmental ...
