Biochar shows benefits as manure lagoon cover

Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few.

Spying on malaria parasites at -196 Celsius

MALARIA RESEARCH:  By combining two advanced microscope techniques an international team of scientists led by postdoc Sergey Kapishnikov from the Niels Bohr Institute has managed to obtain new information about the ravaging mode of operation applied by malaria parasites when attacking their victims. This information can be utilized when designing new medication to more effectively fight malaria - a disease claiming over 400.000 lives each year, a majority of whom are infants.

Scientists produce battle-plan blueprints for attacking disease-causing bacteria

Scientists from Trinity College Dublin have gained key structural insights into the machinery employed by opportunistic, disease-causing bacteria, which may help chemists design new drugs to inhibit them.

Early diagnostic imaging to prevent kidney disease

Osaka University researchers, in collaboration with several Japanese companies, translate neuroimaging tools to study renal fibrosis in rat kidney. The technique is expected to replace the invasive biopsies currently used to identify patients at risk of developing chronic kidney disease.

Post-Glacial History of Lake of the Woods

The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice melted from the continent. This relationship and the post-glacial history of Lake of the Woods -- one of the largest lake complexes in North America and the source of water for the city of Winnipeg -- is presented for the first time in a new study by five Canadian researchers.

Can Poor Air Quality Mask Global Warming's Effects?

During the 20th century, the average temperature of the continental United States rose by almost 1 degree Fahrenheit (0.5 degree Celsius) -- everywhere, that is, except in the Southeast.

Exposure to toxins in e-cig vapor varies depending on scenario

E-cigarettes are often perceived to be less harmful than their traditional counterparts, but they could still expose the people who “vape” and those around them to harmful compounds. Researchers now report in ACS’ journal Environmental Science & Technology that heavy use and secondhand emissions could lead to inhaled levels of toxins that exceed set exposure limits. But under typical use, secondhand exposure would have a lower impact on health than second- and third-hand cigarette smoke.

Phytoplankton and chips

Microbes mediate the global marine cycles of elements, modulating atmospheric carbon dioxide and helping to maintain the oxygen we all breathe, yet there is much about them scientists still don’t understand. Now, an award from the Simons Foundation will give researchers from MIT's Darwin Project access to bigger, better computing resources to model these communities and probe how they work.

The simulations of plankton populations made by Darwin Project researchers have become increasingly computationally demanding. MIT Professor Michael "Mick" Follows and Principal Research Engineer Christopher Hill, both affiliates of the Darwin Project, were therefore delighted to learn of their recent Simons Foundation award, providing them with enhanced compute infrastructure to help execute the simulations of ocean circulation, biogeochemical cycles, and microbial population dynamics that are the bread and butter of their research.

Power-to-Liquid: 200 Liters of Fuel from Solar Power and the Air's Carbon Dioxide

Production of liquid fuels from regenerative electric power is a major component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air’s carbon dioxide by Fischer-Tropsch synthesis under the SOLETAIR project. Here, INERATEC, a spinoff of Karlsruhe Institute of Technology (KIT), cooperates with Finnish partners. The mobile chemical pilot plant that can be used decentrally produces gasoline, diesel, and kerosene from regenerative hydrogen and carbon dioxide. It is so compact that it fits into a shipping container.

Great Lakes scientists identify research challenges

The Great Lakes could be in hot water if the quality of the research and partnerships are not improved, warns a University of Windsor professor.

“Fresh water is arguably the most important issue for the world going forward to support the planet,” said University of Windsor professor Aaron Fisk, the Tier 1 Canada Research Chair in Changing Great Lakes Ecosystems. “But the amount of resources that are dedicated to the Great Lakes from the U.S. and Canada is only a fraction of what is funded for the oceans.”
