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.

Is aging inevitable? Not necessarily for sea urchins
Scientists are studying the regenerative capacity of sea urchins in hopes that a deeper understanding of the process of regeneration, which governs the regeneration of aging tissues as well as lost or damaged body parts, will lead to a deeper understanding of the aging process in humans, with whom sea urchins share a close genetic relationship.

Scientists explore new concepts of plant behavior, interactions
While a lot is already known about plant perception, our ecological understanding of plants has largely focused on seeing plants as the sum of a series of building blocks or traits. A new collection of articles gathers researchers who have taken a different approach, theorizing plant activity in terms of behavior.

Blockade of histamine receptors suppresses intestinal anaphylaxis in peanut allergy
Simultaneous pre-treatment with antihistamines that block both the H1 and H4 antihistamine receptors suppressed the gastrointestinal symptoms of food allergy in mice, according to researchers.
