Hydrologic simulation models that inform policy decisions are difficult to interpret

Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices. Numerical models have become increasingly easy to employ with advances in computer technology...

Black holes stunt growth of dwarf galaxies

Astronomers have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star formation.

How preprocessing methods affect the conversion efficiency of biomass energy production

Research on energy production from biomass usually focuses on the amount of energy generated. But it is also important to consider how much energy goes into the process, a component that is often neglected. A study from the University of Illinois takes a look at the bioconversion efficiency of two products often used as biomass for energy production, miscanthus giganteus and sugarcane bagasse.

New tool enables Nova Scotia lobster fishery to address impacts of climate change

Researchers use long-term survey data sets and climate models to help fishing communities plan for a warmer ocean. Researchers have developed a tool that incorporates projected changes in ocean climate onto a geographic fishery management area. Now fishermen, resource managers, and policy-makers can use it to plan for the future sustainability of the lobster fishery in Nova Scotia and Canadian...

Nanoscale manipulation of light leads to exciting new advancement

Controlling the interactions between light and matter has been a long-standing ambition for scientists seeking to develop and advance numerous technologies that are fundamental to society. With the boom of nanotechnology in recent years, the nanoscale manipulation of light has become both, a promising pathway to continue this advancement, as well as a unique challenge due to new behaviors that...

Alexei Leonov, first human to walk in space, dies aged 85

The Soviet cosmonaut almost didn’t make it back into his capsule in 1965, when his suit inflated in the space vacuumAlexei Leonov, the legendary Soviet cosmonaut who became the first human to walk in space 54 years ago, has died in Moscow at 85.The Russian space agency Roscosmos announced the news on its website on Friday, but gave no cause of death. Leonov had health issues for several years,...
