New studies quantify the impacts of water use on diversity of fish and aquatic insects in NC streams

The health of fish and aquatic insects could be significantly affected by withdrawals of fresh water from the rivers and streams across North Carolina according to a new scientific assessment.

A series of studies were conducted by a team of researchers, led by Jennifer Phelan, Ph.D., a senior ecologist at RTI International, to understand the relationships between changes in streamflow and the diversity of fish and richness of aquatic insects.

Dream of energy-collecting windows is one step closer to reality

Discovery could lower cost and expand possibilities for building-integrated solar energy collection

Researchers at the University of Minnesota and University of Milano-Bicocca are bringing the dream of windows that can efficiently collect solar energy one step closer to reality thanks to high tech silicon nanoparticles.

The researchers developed technology to embed the silicon nanoparticles into what they call efficient luminescent solar concentrators (LSCs). These LSCs are the key element of windows that can efficiently collect solar energy. When light shines through the surface, the useful frequencies of light are trapped inside and concentrated to the edges where small solar cells can be put in place to capture the energy.

The research is published today in Nature Photonics, a peer-reviewed scientific journal published by the Nature Publishing Group.

OFFSHORE WIND PUSH

Researchers show US grid can handle more offshore wind power, cutting pollution and power costs

Injecting large amounts of offshore wind power into the U.S. electrical grid is manageable, will cut electricity costs, and will reduce pollution compared to current fossil fuel sources, according to researchers from the University of Delaware and Princeton University who have completed a first-of-its-kind simulation with the electric power industry.

Transforming restaurant waste into fuel

When most people look at discarded vegetable oil—browned and gritty from frying food—they likely see nothing more than waste.

But to Ajay Dalai, a professor in the Department of Chemical and Biological Engineering, the cooking process creates a byproduct that has newfound potential as a source of fuel and biolubricant.

The invisible clean-up crew: Engineering microbial cultures to destroy pollutants

University of Toronto engineering professor Elizabeth Edwards is internationally recognized for using biotechnology to clean up industrial solvents in soil and groundwater. Her technique earned her the prestigious Killam Prize in 2016 and has already been used to restore more than 500 sites around the world.

Fifth of food lost to over-eating and waste

Almost 20 per cent of the food made available to consumers is lost through over-eating or waste, a study suggests. 

The world population consumes around 10 per cent more food than it needs, while almost nine per cent is thrown away or left to spoil, researchers say.

Efforts to reduce the billions of tonnes lost could improve global food security – ensuring everyone has access to a safe, affordable, nutritious diet – and help prevent damage to the environment, the team says.

NASA's Fermi Finds Possible Dark Matter Ties in Andromeda Galaxy

NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Dying Patients Who Received Palliative Care Visited the ER Less

Community-based palliative care – care delivered at home, not the hospital – was associated with a 50 percent reduction in emergency department visits for patients in their last year of life.  The results of an Australian study were published online February 3rd in Annals of Emergency Medicine(“The Association of Community-Based Palliative Care with Reduced Emergency Department Visits in the Last Year of Life Varies by Patient Factors”).

Winners, losers among fish when landscape undergoes change

As humans build roads, construct buildings and develop land for agriculture, freshwater ecosystems respond - but not always in the ways one might expect.
