Quest for education creating graying ghost towns at top of the world
Ethnic Tibetan communities in Nepal's highlands are rapidly shrinking as more parents send their children away for a better education and modern careers, a trend that threatens to create a region of graying ghost towns at the top of the world, according to a study that includes Dartmouth College.

Familiar yet strange: Water's 'split personality' revealed by computer model
Using computer models, Princeton University researchers found that as water freezes it takes on a sort of split personality wherein, at very cold temperatures and above a certain pressure, it may spontaneously split into two liquid forms. Finding this dual nature could lead to a better understanding of how water behaves in high-altitude clouds, which could improve the predictive ability of current weather and climate models.

Dynamic spectroscopy duo
Berkeley Lab researchers have developed a new technique called two-dimensional electronic-vibrational spectroscopy that can be used to study the interplay between electrons and atomic nuclei during a photochemical reaction. Photochemical reactions are critical to a wide range of natural and technological phenomena, including photosynthesis, vision, nanomaterials and solar energy.

Strange physics turns off laser
Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter.

Flagship US Arctic research facility welcomes EU scientists
Two European Union scientists won an international competition to conduct research at the United States' flagship Arctic research facility in northern Alaska during the 2014 field season. The University of Alaska Fairbanks' Institute of Arctic Biology is welcoming the scientists at the Toolik Field Station in July and August. A third EU scientist will be going to the Barrow Environmental Observatory.

Controlling ragweed pollen in Detroit: A no-mow solution for Motown?
When it comes to controlling hay fever-triggering ragweed plants on Detroit vacant lots, occasional mowing is worse than no mowing at all, and promoting reforestation might be the best solution.

Researchers use virus to reveal nanopore physics
Nanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers from Brown have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.

Systematic Biology
UMD-led public computational biology web service gains popularity gives anyone with a computer terminal access to a worldwide grid for computational biology. The grid offers a service called GARLI, which reconstructs and predicts the genetic relationships between biological samples. To date, over 17,000 volunteers from 146 countries have run computational biology analyses on their computers. Researchers have used the grid system to simulate pandemic flu risk and trace the lineage of ancient moth species and have published 61 papers detailing their findings.

Scientists identify Deepwater Horizon Oil on shore even years later, after most has degraded
Years after the 2010 Deepwater Horizon Oil spill, oil continues to wash ashore as oil-soaked 'sand patties,' persists in salt marshes abutting the Gulf of Mexico, and questions remain about how much oil has been deposited on the seafloor. Scientists from Woods Hole Oceanographic Institution and Bigelow Laboratory for Ocean Sciences have developed a unique way to fingerprint oil, and have successfully identified Macondo Well oil, even after most of it has degraded.

New evidence for oceans of water deep in the Earth
Northwestern University and University of New Mexico researchers report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form -- the ingredients for water are bound up in rock deep in the Earth's mantle -- the discovery may represent the planet's largest water reservoir. The researchers have found deep pockets of magma located about 400 miles beneath North America, a likely signature of the presence of water at these depths.
