Scientists create computing building blocks from bacteria and DNA
Scientists have successfully demonstrated that they can build some of the basic components for digital devices out of bacteria and DNA, which could pave the way for a new generation of biological computing ...
Microbiologist discovers new super-preservative
Bacteria in mouth and gut also found in arteries
(PhysOrg.com) -- The same types of bacteria found in arterial plaque, which causes atherosclerosis, are also found in the mouth and gut, according to the first general survey of all bacteria found in plaques ...
Of bugs and brains: Researchers discover that gut bacteria affect multiple sclerosis
Biologists at the California Institute of Technology have demonstrated a connection between multiple sclerosis (MS) -- an autoimmune disorder that affects the brain and spinal cord -- and gut bacteria.
Galectins direct immunity against bacteria that employ camouflage
Our bodies produce a family of proteins that recognize and kill bacteria whose carbohydrate coatings resemble those of our own cells too closely, scientists have discovered.
Cow manure harbors diverse new antibiotic resistance genes
Manure from dairy cows, which is commonly used as a farm soil fertilizer, contains a surprising number of newly identified antibiotic resistance genes from the cows' gut bacteria. The findings, reported in mBio the online ...
Lifestyle determines gut microbes
An international team of researchers has for the first time deciphered the intestinal bacteria of present-day hunter-gatherers.
Scientists investigate the fiber of our being
We are all aware of the health benefits of "dietary fibre". But what is dietary fiber and how do we metabolise it?
New gut bacterium discovered in termite's digestion of wood
When termites munch on wood, the small bits are delivered to feed a community of unique microbes living in their guts, and in a complex process involving multiple steps, these microbes turn the hard, fibrous ...
Study finds specialized bacterial cells found in the gut produce steroid hormones
The human gut is home to trillions of bacteria, many of which play an important role in helping the body strike a healthy balance. In the gut, bacteria are involved in the synthesis of vitamins, as well as ...
Microbes help beetles defeat plant defenses
Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore, according to a team of Penn State researchers who ...
Newly discovered marine viruses offer glimpse into untapped biodiversity
(Phys.org) —Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown viruses that infect different strains of marine bacteria.
Buckling up to turn: Marine microbes change swimming direction via a high-speed mechanical instability
Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria, including the Escherichia coli (E. coli) living in the human gut, have multiple flagella ...
Novel enzyme from tiny gribble could prove a boon for biofuels research
(Phys.org) —Researchers from the United Kingdom, the Energy Department's National Renewable Energy Laboratory (NREL), and the University of Kentucky have recently published a paper describing a novel cellulose-degrading ...
