Antibiotics 2.0: The atomic structure and mechanism of mammalian host-defense peptides
Wires turn salt water into freshwater
Tiny power generator runs on spit
Saliva-powered micro-sized microbial fuel cells can produce minute amounts of energy sufficient to run on-chip applications, according to an international team of engineers.
Solar-induced hybrid fuel cell produces electricity directly from biomass
Although low temperature fuel cells powered by methanol or hydrogen have been well studied, existing low temperature fuel cell technologies cannot directly use biomass as a fuel because of the lack of an ...
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 ...
Boldly illuminating biology's 'dark matter'
Is space really the final frontier, or are the greatest mysteries closer to home? In cosmology, dark matter is said to account for the majority of mass in the universe, however its presence is inferred by ...
Breakthrough in race to create 'bio-batteries'
(Phys.org) —Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.
Unique salt allows energy production to move inland
Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, Penn State researchers can combine bacterial ...
Last universal common ancestor more complex than previously thought
Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical ...
Saltwater boosts microbial electrolysis cells to cleanly produce hydrogen
A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, ...
Using microbes to generate electricity
Using bacteria to generate energy is a signifiant step closer following a breakthrough discovery by scientists at the University of East Anglia.
Scientists identify a deadly tool in Salmonella's bag of tricks
The potentially deadly bacterium Salmonella possesses a molecular machine that marshals the proteins it needs to hijack cellular mechanisms and infect millions worldwide.
Microbial hair -- it's electric: Specialized bacterial filaments shown to conduct electricity
(PhysOrg.com) -- Some bacteria grow electrical hair that lets them link up in big biological circuits, according to a University of Southern California biophysicist and his collaborators.
