West Virginia groundwater not affected by fracking, but surface water is
Three years of fracking has not contaminated groundwater in northwestern West Virginia, but accidental spills of wastewater from fracked wells may pose a threat to surface water, according to a study led by scientists at Duke University. The scientists used a broad suite of geochemical and isotopic tracers to sample for contaminants in 112 water wells near shale gas sites, including 20 wells that were sampled both before and after fracking began.

The placebo effect can mend a broken heart too, CU Boulder study shows
Feeling heartbroken from a recent breakup? Just believing you're doing something to help yourself get over your ex can influence brain regions associated with emotional regulation and lessen the perception of pain. That's the takeaway from a new University of Colorado Boulder study that measured the neurological and behavioral impacts the placebo effect had on a group of recently broken-hearted volunteers.

Next-generation microscopy
A novel microscopy method allows unprecedented insights into the spatial organization and direct interactions of immune cells within blood and liquid multi-lineage tissues. The assay, called 'Pharmacoscopy,' is able to determine the immunomodulatory properties of drugs within large libraries on immune cells in high resolution and high throughput. Introduced in Nature Chemical Biology, Pharmacoscopy enables new possibilities for drug discovery, particularly in cancer immunotherapy, personalized medicine, and research on signaling pathways of the immune system.

Discovery offers new hope to repair spinal cord injuries
Scientists at the Gladstone Institutes created a special type of neuron from human stem cells that could potentially repair spinal cord injuries. These cells, called V2a interneurons, transmit signals in the spinal cord to help control movement. When the researchers transplanted the cells into mouse spinal cords, the interneurons sprouted and integrated with existing cells.

Freezing lithium batteries may make them safer and bendable
Columbia Engineering Professor Yuan Yang has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage. The study is published online April 24 in Nano Letters.

Research sheds new light on forces that threaten sensitive coastlines
Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region, according to research published by scientists at Indiana University and North Carolina State University. The study found that 17 percent of land loss in the area resulted from pond expansion, much of it caused by waves that eroded away the edges of the pond.

Finding order and structure in the atomic chaos where materials meet
Materials science researchers have developed a model that can account for irregularities in how atoms arrange themselves at the so-called 'grain boundaries' -- the interface where two materials meet. By describing the packing of atoms at these interfaces, the tool can be used to help researchers determine how grain boundaries affect the properties of metal alloys and other materials.

Bergamotene -- alluring and lethal for Manduca sexta
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, describe a gene in Nicotiana attenuata which enables the plant to solve the dilemma that arises when a pollinator is also an herbivore. NaTPS38 regulates the production of (E)-alpha-bergamotene. At night, the tobacco flowers produce this volatile which is attractive to tobacco hawkmoths, during the day, the tobacco leaves emit the compound to lure predatory bugs to feed on the moths' larvae.

Same but different
Bacterial populations pose an intriguing puzzle: in so-called isogenic populations, all bacteria have the same genes, but they still behave differently, for example grow at different speeds. Researchers at the Institute of Science and Technology Austria (IST Austria) now solved a part of this puzzle by studying how the bacterium Escherichia coli divides up a protein complex that detoxifies cells by pumping multiple drugs such as antibiotics out of the cell.

Why children struggle to cross busy streets safely
Researchers have found children up to early teenagers lack the perceptual judgment and motor skills to safely cross a busy road consistently. Children placed in realistic, simulated environments were tested for their road-crossing abilities. Those from 6 to 12 years of age had trouble crossing the street, with accident rates as high as 8 percent with 6-year-olds. Results appear in the Journal of Experimental Psychology: Human Perception and Performance.

3-D-printable implants may ease damaged knees
A cartilage-mimicking material created by researchers at Duke University may allow surgeons to 3-D print knee menisci or other replacement parts that are custom-shaped to each patient's anatomy. The hydrogel-based material is the first to match human cartilage in strength and elasticity while also remaining 3-D-printable and stable inside the body.

Researchers quantify grasslands' carbon storage value
Grasslands that feature diverse plant species have more carbon storage capacity than less-diverse grasslands, largely because the former produce more biomass, the researchers say. They found that increasing the number of plant species from one to 10 had twice the value of increasing from one to two species, from the standpoint of carbon storage capacity.

Busy city living makes some house finches more savvy than others
House finches that frequent North American cities and towns are better at solving problems than their rural counterparts. They are able to solve new problems even when humans are around, says Meghan Cook of Arizona State University in the US, lead author of a study in Springer's journal Behavioral Ecology and Sociobiology. The study investigated how increased urbanization and human presence affects the behavior and foraging habits of wildlife, and how birds, in particular, cope.

New research from Carnegie Mellon University's College of Engineering and the University of Pittsburgh reveals that motor cortical neurons optimally adjust how they encode movements in a task-specific manner. The findings enhance our understanding of how the brain controls movement and have the potential to improve the performance and reliability of brain-machine interfaces, or neural prosthetics, that assist paralyzed patients and amputees.
