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. ...
Bacteria may allow animals to send quick, voluminous messages
Twitter clips human thoughts to a mere 140 characters. Animals' scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them.
3-D printing allows scientists to design bacterial communities
By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
Maize and bacteria: A 1-2 punch knocks copper out of stamp sand
Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to ...
Pigment or bacteria? Researchers re-examine the idea of 'color' in fossil feathers
Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University ...
First look at how individual Staphylococcus cells adhere to nanostructures could lead to new ways to thwart infections
The bacterium Staphylococcus aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to me ...
Researchers discover how soils control atmospheric hydrogen
(Phys.org) —University of Otago researchers are helping to clear up an enduring mystery regarding the composition of the Earth's atmosphere. They have discovered the microbial soil processes that help ensure ...
Vitamin water: Measuring essential nutrients in the ocean
The phrase, 'Eat your vitamins,' applies to marine animals just like humans. Many vitamins, including B-12, are elusive in the ocean environment.
