FROSTSBURG, MD (October 14, 2015)--A new study shows that surface water temperature in the Chesapeake Bay is increasing more rapidly than air temperature, signaling a need to look at the impact of warming waters on one of the largest and most productive estuaries in the world. The study, completed by Haiyong Ding and Andrew Elmore of the University of Maryland Center for Environmental Science's Appalachian Laboratory, was published in the October issue of Remote Sensing of Environment.

A team of Australian scientists has produced a precision laser device that creates an accurate international standard for temperature.

Published today in the journal Nature Communications, the researchers from the University of Adelaide, University of Queensland and University of Western Australia, have come up with a new way to determine Boltzmann's constant, a number which relates the motion of individual atoms to their temperature.

In collaboration with colleagues from Aalborg University, Technical University of Denmark (DTU) researchers have studied genes from wastewater treatment plants that may help bacteria to develop antimicrobial resistance. Their findings demonstrate that the treatment plants contain a great many genes that may generate resistance to a wide variety of antimicrobial agents.

In a development that could revolutionize electronic ciruitry, a research team from the University of Wisconsin at Madison (UW) and the U.S. Department of Energy's Argonne National Laboratory has confirmed a new way to control the growth paths of graphene nanoribbons on the surface of a germainum crystal.

Germanium is a semiconductor and this method provides a straightforward way to make semiconducting nanoscale circuits from graphene, a form of carbon only one atom thick.

The method was discovered by UW scientists and confirmed in tests at Argonne.

Washington D.C., Oct. 13, 2015 -- A simple new electron-beam multilayer deposition technique for creating intracavity contacts -- an important component of gallium nitride-based (III-nitride) vertical-cavity surface-emitting lasers (VCSELs) -- not only yields intriguing optoelectronic properties but also paves the way for others entering this realm of research. The new technique was developed by a team of researchers at the University of California, Santa Barbara.

People who believe that climate change is increasing the risk of devastating wildfires in Colorado are no more likely to take mitigation actions to protect their property, a new study led by researchers at the University of Colorado Boulder and the U.S. Forest Service has found.
