Microbes help produce serotonin in gut
Although serotonin is well known as a brain neurotransmitter, it is estimated that 90 percent of the body's serotonin is made in the digestive tract. In fact, altered levels of this peripheral serotonin has been linked to diseases such as irritable bowel syndrome, cardiovascular disease, and osteoporosis. New research at Caltech, published in the April 9 issue of Cell, shows that certain bacteria in the gut are important for the production of peripheral serotonin.

Flip-flopping black holes spin to the end of the dance
Researchers at Rochester Institute of Technology simulated the merger of binary black holes and noticed that one black hole completely changes the orientation of its spin. Their findings have could affect how we understand galactic evolution, cosmology and gravitational physics. Physical Review Letters published the research results, which the authors will present at the American Physical Society meeting on April 14.

'Warm blob' in Pacific Ocean linked to weird weather across the US
An unusually warm patch of surface water, nicknamed 'the blob' when it emerged in early 2014, is part of a Pacific Ocean pattern that may be affecting everything from West Coast fisheries and water supplies to East Coast snowstorms.

Every dogwood has its day: Dogwood Genome Project calls on citizen scientists for help
The flowering dogwood tree is associated with the beginning of spring throughout much of the US. Now, thanks in part to a $1.4 million grant from the National Science Foundation, a group of researchers from universities across the Southeast have joined forces to understand the genetics of this iconic tree. For their project to be a success, the researchers will have to collect data, and they're asking dogwood lovers and science enthusiasts to help.

Bacteria inhibit bat-killing fungus, could combat white-nose syndrome
Bacteria found naturally on some bats may prove useful in controlling the deadly fungal disease known as white-nose syndrome, which has devastated bat populations throughout eastern North America and continues to spread across the continent. Scientists at UC Santa Cruz isolated bacteria that strongly inhibited the growth of the white-nose syndrome fungus in laboratory tests.

The rest of the brain gets in the way
In a new study, researchers measured the connections between different brain regions as participants learned to play a simple game. The differences in neural activity between the quickest and slowest learners provide new insight into what is happening in the brain during the learning process and the role that interactions between different regions play. Their findings suggest that recruiting unnecessary parts of the brain for a given task, akin to over-thinking the problem, plays a critical role in this difference.

Gotcha! Ultra-realistic robot proves there's more than 1 way to scare a fish
Researchers have published the first study showing that, in a side-by-side comparison, a robotic predator can frighten zebrafish just as well as the real thing. Their results may help advance understanding of fear and anxiety in animal populations, including humans. Zebrafish are increasingly taking the place of more complex animals in behavioral studies. Experiments have shown the advantages of using robots in studies of fish behavior, including repeatability and consistency.

This behavior affects the peaks and valleys in the approximately 11-year solar cycle, sometimes amplifying and sometimes weakening the solar storms that can buffet Earth's atmosphere.

Northern coastal marshes more vulnerable to nutrient pollution
Salt marshes at higher latitudes, including those in densely populated coastal regions of New England and Europe, are more vulnerable to the effects of eutrophication, which, if left unchecked, can trigger intense overgrazing by marsh herbivores that can destabilize marshes and reduce their ability to defend shorelines from erosion. Geography and evolution both play roles in making these marshes more susceptible to nutrient loading and overgrazing than their counterparts in the tropics.
