Deep Earth electrical grid mystery solved      (via sciencedaily.com)     Original source 

To 'breathe' in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons, produced during the 'burning' of nutrients, to electric hairs called nanowires projecting from their surface.

Bacteria subtype linked to growth in up to 50% of human colorectal cancers      (via sciencedaily.com)     Original source 

Researchers have found that a specific subtype of a microbe commonly found in the mouth is able to travel to the gut and grow within colorectal cancer tumors. This microbe is also a culprit for driving cancer progression and leads to poorer patient outcomes after cancer treatment. The findings could help improve therapeutic approaches and early screening methods for colorectal cancer, which is the second most common cause of cancer deaths in adults in the U.S. according to the American Cancer Society.

Craving snacks after a meal? It might be food-seeking neurons, not an overactive appetite      (via sciencedaily.com)     Original source 

Psychologists have discovered a circuit in the brain of mice that makes them crave food and seek it out, even when they are not hungry. When stimulated, this cluster of cells propels mice to forage vigorously and to prefer fatty and pleasurable foods like chocolate over healthier foods like carrots.

A protein found in human sweat may protect against Lyme disease      (via sciencedaily.com)     Original source 

Human sweat contains a protein that may protect against Lyme disease. About one-third of the population carries a genetic variant of this protein that is associated with Lyme disease in genome-wide association studies.

Genes identified that allow bacteria to thrive despite toxic heavy metal in soil      (via sciencedaily.com)     Original source 

Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to not only thrive in otherwise toxic soils but help plants grow there as well. A research team pinpointed a set of genes in wild soil bacteria that allows them to do this in serpentine soils which have naturally high concentrations of toxic nickel. The genetic discovery could help inform future bioremediation efforts that seek to return plants to polluted soils.

Industrial societies losing healthy gut microbes      (via sciencedaily.com)     Original source 

Our eating habits in industrialized societies are far removed from those of ancient humans. This is impacting our intestinal flora, it seems, as newly discovered cellulose degrading bacteria are being lost from the human gut microbiome, especially in industrial societies.

Newborn piglets serve as a model for studying influenza      (via sciencedaily.com)     Original source 

Although prevention and treatment strategies are available for influenza, they are not sufficient for vulnerable populations such as young children and newborns. A team of researchers has studied newborn piglets to better understand the progression of influenza infections.

Engineers measure pH in cell condensates      (via sciencedaily.com)     Original source 

In a first for the condensate field, researchers have figured out how nucleolar sub-structures are assembled. This organization gives rise to unique pH profiles within nucleoli, which they measured and compared with the pH of nearby non-nucleolar condensates including nuclear speckles and Cajal bodies.

'Noisy' roundworm brains give rise to individuality      (via sciencedaily.com)     Original source 

Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.

Gut bacteria make neurotransmitters to shape the newborn immune system      (via sciencedaily.com)     Original source 

Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.

Even inactive smokers are densely colonized by microbial communities      (via sciencedaily.com)     Original source 

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

Infections from these bacteria are on the rise: New blood test cuts diagnosis time from months to hours      (via sciencedaily.com)     Original source 

Researchers have designed a platform to perform blood-based diagnoses of nontuberculosis mycobacteria, simplifying and shortening a long-complicated procedure from 6 months to 2 hours. Rapid, accurate diagnosis has never been more important as cases of NTM infections have continued to increase annually, spreading from subtropical regions to more temperate zones in part due to global climate change.
