KNOXVILLE, Tenn. - Two researchers at the University of Tennessee Institute of Agriculture find that farmers located closer to city centers seem to have a locational advantage in transportation over their long distance, conventional food supply chain competitors.

Astronomers at The University of Nottingham have released spectacular new infrared images of the distant Universe, providing the deepest view ever obtained over a large area of sky. The team, led by Omar Almaini, Professor of Astrophysics in the School of Physics and Astronomy, is presenting their results at the National Astronomy Meeting taking place this week at the University's Jubilee Campus.
Scientists from Moscow Institute of Physics and Technology (MIPT), the Institute for Theoretical and Experimental Physics, and the National Research University Higher School of Economics have devised a method of distinguishing black holes from compact massive objects that are externally indistinguishable from one another. The method involves studying the energy spectrum of particles moving in the vicinity -- in one case it will be continuous and in the other it will be discrete. The findings have been published in Physical Review D.
Alexandria, VA - Last summer, while the abandoned Gold King Mine in Colorado was being studied for acid mine drainage, the earthen plug blew out, releasing millions of gallons of acid mine water into the Animas River, which eventually drains into the San Juan and Colorado rivers and ultimately Lake Powell. The images were startling, but this event added momentum to the national dialog on remediating abandoned mine lands. EARTH Magazine explores the role geoscience plays in this process.
CORVALLIS, Ore. - Engineers at Oregon State University have created a new computer modeling package that people anywhere in the world could use to assess the potential of a stream for small-scale, "run of river" hydropower, an option to produce electricity that's of special importance in the developing world.
The system is easy to use; does not require data that is often unavailable in foreign countries or remote locations; and can consider hydropower potential not only now, but in the future as projected changes in climate and stream runoff occur.
In less than a week, the spacecraft Juno will arrive at Jupiter, the culmination of a five-year, billion-dollar journey. It's mission: to peer deep inside the gas giant and unravel its origin and evolution. One of the biggest mysteries surrounding Jupiter is how it generates its powerful magnetic field, the strongest in the solar system.
Researchers have developed a new method for detecting and measuring one of the most powerful, and most mysterious, events in the Universe - a black hole being kicked out of its host galaxy and into intergalactic space at speeds as high as 5000 kilometres per second.
PULLMAN, Wash. - Washington State University researchers have developed a unique, multifunctional smart material that can change shape from heat or light and assemble and disassemble itself. They have filed a provisional patent on the work.
This is the first time researchers have been able to combine several smart abilities, including shape memory behavior, light-activated movement and self-healing behavior, into one material. They have published their work in ACS Applied Materials & Interfaces.
BOSTON (Embargoed until 2 PM EDT, June 29, 2016)--Butter consumption was only weakly associated with total mortality, not associated with cardiovascular disease, and slightly inversely associated (protective) with diabetes, according to a new epidemiological study which analyzed the association of butter consumption with chronic disease and all-cause mortality.
NASA researchers have found that several volcanic deposits on Mercury's surface require mantle melting to have started close to the planet's core-mantle boundary, which lies only 400km below the planets surface and making it unique in the solar system. This is reported at the Goldschmidt conference in Yokohama, Japan.
An international team of scientists, led from Durham's Institute for Computational Cosmology (ICC), used new computer modelling of the Universe to investigate the colours that galaxies have and what those colours might tell us about how galaxies evolve.
Using the state-of-the-art EAGLE simulations, the researchers modelled how both the ages of stars in galaxies and what those stars are made from translate into the colour of light that they produce.
The research team said its simulations showed that colours of galaxies can also help diagnose how they evolve.
In a small study to determine the best way to assess the operating skills of would-be orthopaedic surgeons, Johns Hopkins researchers found that tracking the trainees' performance on cadavers using step-by-step checklists and measures of general surgical skills works well but should be coupled with an equally rigorous system for tracking errors.
Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them.
Their method directly compares data from the Laser Interferometer Gravitational-wave Observatory to cutting-edge numerical simulations of binary black holes, including simulations performed at RIT.
The long-lasting effects of El Niño are projected to cause an intense fire season in the Amazon, according to the 2016 seasonal fire forecast from scientists at NASA and the University of California, Irvine.
El Niño conditions in 2015 and early 2016 altered rainfall patterns around the world. In the Amazon, El Niño reduced rainfall during the wet season, leaving the region drier at the start of the 2016 dry season than any year since 2002, according to NASA satellite data.
In the face of climate change impact and inevitable sea level rise, Cornell and Scenic Hudson scientists studying New York's Hudson River estuary have forecast new intertidal wetlands, comprising perhaps 33 percent more wetland area by the year 2100.
"In other parts of the world, sea level rise has led to net losses of tidal wetland and to permanent inundation," said Magdeline Laba, Cornell senior research associate in soil and crop sciences.
