Study defines thunderstorm asthma epidemic conditions
April 19, 2017 11:07 AM - University of Georgia

As allergy sufferers can attest, thunderstorm activity can exacerbate asthma and respiratory ailments.

In fall 2016, when strong storms moved across southeastern Australia, a major thunderstorm asthma epidemic struck Melbourne and the surrounding area. High grass pollen concentrations dispersed by strong, gusty winds led to multiple deaths and a flood of residents seeking medical attention for respiratory problems.

UNH Helps Lead the Way for Campuses to Measure Their Nitrogen Footprints
April 18, 2017 06:33 PM - University of New Hampshire

Sustainability leadership efforts at the University of New Hampshire have contributed to a groundbreaking initiative to measure and reduce the nitrogen footprint left behind by campus activities like food waste and energy consumption. The new research is highlighted in the April 2017 special issue of Sustainability: The Journal of Record. The publication outlines research being done at UNH, and seven other institutions, to reduce emissions of reactive nitrogen (all forms of nitrogen except unreactive N2 gas) and prevent negative impacts on such things as water quality, air pollution, and climate change.

Track down water pollution through DNA of algae
April 18, 2017 05:08 PM - University of Geneva

Diatoms are a group of unicellular algae particularly sensitive to changes that affect their aquatic environment. This is why they are used as bioindicators for the biological monitoring of water quality. However, their microscopic identification in river samples requires a lot of time and skills. Biologists from the University of Geneva (UNIGE), Switzerland, have succeeded in establishing a water quality index based solely on the DNA sequences of the diatoms present in the samples, without needing to identify each species visually. This study, published in the journal Molecular Ecology Resources, presents a revolutionary tool to process a very large number of samples in parallel, allowing wide coverage of the monitored sites in a reduced time and at a lower cost.

Landslides on Ceres Reflect Hidden Ice
April 18, 2017 11:00 AM - Georgia Institute of Technology

Massive landslides, similar to those found on Earth, are occurring on the asteroid Ceres. That’s according to a new study led by the Georgia Institute of Technology, adding to the growing evidence that Ceres retains a significant amount of water ice.

NREL Establishes World Record for Solar Hydrogen Production
April 18, 2017 10:56 AM - DOE/National Renewable Energy Laboratory

Scientists at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) recaptured the record for highest efficiency in solar hydrogen production via a photoelectrochemical (PEC) water-splitting process.

Mechanism behind the electric charges generated by photosynthesis -A step towards artificial photosynthesis
April 18, 2017 10:53 AM - Kobe University

Photosynthesis requires a mechanism to produce large amounts of chemical energy without losing the oxidative power needed to break down water. A Japanese research team has clarified part of this mechanism, marking another step towards the potential development of artificial photosynthesis. The findings were published on February 27 in the online edition of The Journal of Physical Chemistry Letters.

Arctic River Ice Deposits Rapidly Disappearing
April 18, 2017 10:32 AM - American Geophysical Union

Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.
