New insight into bacterial cell division could aid in fight against harmful bacteria
Escherichia coli are bacteria that live all around and inside of us. Most E. coli are harmless, but some strains can cause illness, and can even, in extreme cases, be deadly. With recent outbreaks of E. coli around the world, there is a fear of acquiring an infection from these bacteria. An important component of fighting these kinds of bad bacteria is a better understanding of how bacteria divide and multiply.

'Phage' fishing yields new weapon against antibiotic resistance
Researchers were fishing for a new weapon against antibiotic resistance and found one floating in a Connecticut pond. A virus called a bacteriophage, found in Dodge Pond in East Lyme, attacks a common multi-drug resistant bacterial pathogen called Pseudomonas aeruginosa, which can lethally infect people with compromised immune systems.

Tiny 'vampires': Paleobiologist finds evidence of predation in ancient microbial ecosystems
A paleobiologist has found evidence of predation in ancient microbial ecosystems dating back more than 740 million years. Using a scanning electron microscope to examine minute fossils, Porter found perfectly circular drill holes that may have been formed by an ancient relation of Vampyrellidae amoebae. These single-celled creatures perforate the walls of their prey and reach inside to consume its cell contents.

Consumer knowledge gap on genetically modified food
While consumers are aware of genetically modified crops and food, their knowledge level is limited and often at odds with the facts, according to a newly published study.

Harnessing nature’s vast array of venoms for drug discovery
Scientists have invented a method for rapidly identifying venoms that strike a specific target in the body -- and optimizing such venoms for therapeutic use.

Silencing cholera's 'social media'
Bacteria use a form of 'social media' communication, quorum sensing, to monitor how many of their species are in the neighborhood. This is important in the pathogenicity of Vibrio cholerae, the cause of cholera. In a new study scientists explore the molecular mechanism whereby the quorum sensing response regulator LuxO regulates V. cholerae's pathogenicity.

Study of fungi-insect relationships may lead to new evolutionary discoveries
Zombie ants are only one of the fungi-insect relationships studied by a team of biologists in a newly compiled database of insect fungi interactions.

Study documents African monkeys eating bats
Primates and bats may interact directly, but their behavioral and predator-prey interactions are poorly documented, and detailed reports of their interactions have been rare, until now. The first study to document monkeys consuming bats with photos and video suggests an alternative pathway for bat-to-monkey disease transmission that has implications for zoonotic disease transmission to humans.

New tools to manipulate biology
Chemistry has provided many key tools and techniques to the biological community in the last twenty years. We can now make proteins that Mother Nature never thought of, image unique parts of live cells and even see cells in live animals. Biologists now take these accomplishments a step further, reporting advances in both how proteins are made and how you can see their expression patterns in live animals.
