Real-time imaging of fish gut ties bacterial competition to gut movements
In recent years, numerous diseases have been tied to variations in gut microbiota. The probiotics industry targets gut and intestinal health by developing products built mostly around enzyme cultures and bacteria. But a new study suggests that the underlying health and physical forces of the gut are as important as the bacteria inside in shaping communities of intestinal microbiota, and offers insights into the problems experienced by humans with a birth defect called Hirschsprung's disease.

Fermenting carbon monoxide into biofuel
Biological engineers have deciphered the cellular strategy to make the biofuel ethanol, using an anaerobic microbe feeding on carbon monoxide -- a common industrial waste gas.

How animals keep their cells identical
A regulatory protein named ERI-1 helps ensure that all cells in a tissue remain identical to one another, a research team has discovered for the first time. The work involved an unusual collaboration between developmental biologists and linguists, with the latter contributing their expertise with machine learning software. The finding could bring biologists one step closer to understanding some cancers and other age-related diseases.

Newly discovered virus a prime suspect in often-fatal beak disorder spreading among birds
Scientists have identified a novel virus -- 'Poecivirus' -- that has been linked to avian keratin disorder (AKD), a disease responsible for debilitating beak overgrowth and whose cause has remained elusive despite more than a decade of research. This new virus is being investigated as a potential cause of AKD and represents a critical step in understanding the emergence of this disease in wild bird populations around the world.

Plasma technology can be tapped to kill biofilms on perishable fruit, foods
Seeing fruit 'turn bad and going to waste' inspired a team of researchers in China to explore using atmospheric pressure nonequilibrium plasma as a novel solution to extend the shelf life of fruit and other perishable foods. Now their computational study of how air plasma interacts with bacterial biofilms on an apple's surface suggests that plasma technology could be used to decontaminate food in the future.

Migratory birds are not a reservoir for highly pathogenic flu viruses, evidence suggests
The H5 avian influenza A virus that devastated North American poultry farms in 2014-15 was initially spread by migratory waterfowl, but evidence suggests such highly pathogenic flu viruses do not persist in wild birds.

Flower bud uniformity beholden to time, space
A study of sepals in Arabidopsis plants reveals the mystery of how uniformity in flowers and organs occurs. In the study, the diverse international team used an interdisciplinary approach that combined expertise in biology, computer science, physics and applied mathematics.

Parasite proteins prompt immune system to fight off ovarian tumors in mice
Scientists identified the specific proteins secreted by the parasite Toxoplasma gondii that cause the immune system in mice to attack established ovarian tumors.

Pathogenic bacteria hitchhiking on tiny plastic particles to North and Baltic Seas?
With increasing water temperatures comes an increasing likelihood of potentially pathogenic bacteria appearing in the North and Baltic Seas. Scientists have now demonstrated that a group of such bacteria known as vibrios can survive on microplastic particles.
