How plants become zombies
(Phys.org) —Forget popular video game Plants Vs. Zombies, some plants are zombies and scientists have uncovered how bacterial parasites turn them into the living dead.
Diagnosing diseases in real time with smartphones
Smartphones are capable of giving us directions when we're lost, sending photos and videos to our friends in mere seconds, and even helping us find the best burger joint in a three-mile radius. But University ...
Scientists combine bacteria with liquid crystals
(Phys.org) —When swimming around, bacteria aren't good with the "pool rules." In small quantities, they'll follow the lanes, but put enough together and they'll begin to create their own flow.
Researchers identify key enzyme found in bacteria responsible for heart valve disease
A disease-causing bacterium found in the mouth needs manganese, a trace mineral, in order to cause a serious heart infection, according to a preclinical study led by researchers at Virginia Commonwealth University ...
Actin cytonauts at play in the cell
Dispersal patterns key to invasive species' success
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting."
Hugging hemes help electrons hop
(Phys.org) —Researchers simulating how certain bacteria run electrical current through tiny molecular wires have discovered a secret Nature uses for electron travel. The results are key to understanding ...
Scientists discover extracellular vesicles produced by ocean microbes
Marine cyanobacteria—tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2—are primary engines of Earth's biogeochemical and nutrient cycles. They nourish other organisms ...
Structure of bacterial nanowire protein hints at secrets of conduction (w/ Video)
(Phys.org) —Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. ...
Revealing camouflaged bacteria
A research team at the Biozentrum of the University of Basel has discovered an protein family that plays a central role in the fight against the bacterial pathogen Salmonella within the cells. The so cal ...
Australian brush-turkey eggs inspire ideas for germ-resistant coatings
(Phys.org) —Rather than sit on its eggs to incubate them, the Australian brush-turkey buries them in rotting vegetation. While bacterial decomposition heats the eggs, it doesn't infect them. University ...
Lifestyle determines gut microbes
An international team of researchers has for the first time deciphered the intestinal bacteria of present-day hunter-gatherers.
Scientists pinpoint when harmless bacteria became flesh-eating monsters
Bacterial diseases cause millions of deaths every year. Most of these bacteria were benign at some point in their evolutionary past, and we don't always understand what turned them into disease-causing pathogens. ...
Sponges that sponge off bacteria
Medical compounds harvested from a marine sponge are actually produced by symbiotic bacteria living in the sponges.
