'First arrival' hypothesis in Darwin's finches gets some caveats
Being first in a new ecosystem provides major advantages for pioneering species, but the benefits may depend on just how competitive later-arriving species are. That is among the conclusions in a new study testing the importance of 'first arrival' in controlling adaptive radiation of species, a hypothesis famously proposed for 'Darwin's Finches,' birds from the Galapagos Islands that were first brought to scientific attention by Darwin.

Rosetta online server that includes everyone
Scientists have developed computer algorithms that are clever enough to map out biomolecules' 3-D forms, or create entirely new ones, based on their DNA or RNA sequence. However, doing so requires powerful supercomputers and specialized software that can take advantage of them.

Study of transgender preschoolers assesses preferences and identity
Gender may be the earliest identity and social category to emerge in development, research suggests, and acquiring knowledge about one's gender is considered a critical part of early childhood development. In one of the first examinations of early gender development among transgender preschoolers, a new study has found that these children were just as likely as nontransgender children to have preferences associated with their gender, and to have as strong and clear a sense of their gender identity.

Penn team identifies genetic target for growing hardier plants under stress
In a new investigation, researchers from the University of Pennsylvania identified two proteins that regulate whether a cell in plant roots forms a hair cell, which increases surface area for absorption, or a non-hair cell. Plants that overexpressed one of these regulators thrived despite being deprived of a key nutrient, phosphorous.

Lyme disease researchers seek consensus as number of cases grows
Scientists have built a large body of knowledge about Lyme disease over the past 40 years, yet controversies remain and the number of cases continues to rise. In the United States, reported cases of Lyme disease, which is transmitted from wild animals to humans by tick bites, have tripled in the past 20 years. A multitude of interacting factors are driving the increase in Lyme disease cases, but their relative importance remains unclear.

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.
