Nanobacteria theory takes a hit
They look like tiny bacteria, have been implicated in several diseases and have even been hailed as a completely overlooked branch of the tree of life. But are 'nanobacteria' genuinely alive? New research suggests that the answer is probably no.

Duke scientists deconstruct process of bacterial division 
Duke University researchers have made a major advance in understanding how bacteria divide. This could lead to new antibiotic treatments that prevent dangerous bacteria from multiplying.

Are sacrificial bacteria altruistic or just unlucky?
An investigation of the genes that govern spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores.

Solving the Z ring's mysteries may lead to new antibiotics
Scientists reported how a belt-like structure called a Z ring, which pinches a rod-shaped bacterium to produce two offspring, can be disabled by a protein called MinC. By exploiting this vulnerability, the researchers said, pharmaceutical companies may find a way to fight infections that no longer respond to older medications.

Alligator blood may put the bite on antibiotic-resistant infections
Despite their reputation for deadly attacks on humans and pets, alligators are wiggling their way toward a new role as potential lifesavers in medicine. They described how proteins in gator blood may provide a source of powerful new antibiotics to help fight infections associated with diabetic ulcers, severe burns, and “superbugs” that are resistant to conventional medication.

Finely tuned WspRs help bacteria beat body by building biofilm
Bacteria are particularly harmful to human health when they band together to form a biofilm—a sheet composed of many individual bacteria glued together—because this can allow them to escape from both antibiotics and the immune system of their host.

New research provides dynamic visualization of simplest circadian clock
Scientists have acquired a more dynamic picture of events that underlie the functions of a bacterial biological clock. New research published online March 13th by Cell Press in the journal Molecular Cell, shows how the simplest organism known to have a circadian clock keeps time and may enhance our understanding of how other organisms establish and govern chronological rhythms.

Research could put penicillin back in battle against antibiotic resistant bugs that kill millions
Research led by the University of Warwick has uncovered exactly how the bacterium Streptococcus pneumoniae has become resistant to the antibiotic penicillin. The same research could also open up MRSA to attack by penicillin and help create a library of designer antibiotics to use against a range of other dangerous bacteria.

Marine bacteria's mealtime dash is a swimming success
Goldfish in an aquarium are able to dash after food flakes at mealtime, reaching them before they sink or are eaten by other fish. Researchers at MIT recently proved that marine bacteria, the smallest creatures in the ocean, behave in a similar fashion at mealtime, using their swimming skills to reach tiny food patches that appear randomly in the ocean blue.

Nature's helpers: Using microorganisms to remove TCE from water
In 2002, Bruce Rittmann, PhD, director of the Biodesign Institute’s Center for Environmental Biotechnology, received a patent for an innovative way to use nature to lend society a hand. He invented a treatment system, called the membrane biofilm reactor (MBfR), which uses naturally occurring microorganisms to remove contaminants from water.
