Harvard University researchers have resolved a conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere.

Engineers find way to evaluate green roofs
Green infrastructure is an attractive concept, but there is concern surrounding its effectiveness. Researchers at the University of Illinois at Urbana-Champaign are using a mathematical technique traditionally used in earthquake engineering to determine how well green infrastructure works and to communicate with urban planners, policymakers and developers.
Green roofs are flat, vegetated surfaces on the tops of buildings that are designed to capture and retain rainwater and filter any that is released back into the environment.
New centre puts UWindsor at the Canadian forefront of alternatives to animal testing
Each year millions of animals are used in Canada for medical research and toxicity testing, but a growing body of scientific evidence points to the difficulties of treating humans like 70-kg mice.
After years of using rodents to conduct heart disease research, Charu Chandrasekera began to question the value of using animals as stand-ins for humans. She lost her fervour for animal research after her father suffered a heart attack, bringing home to her the realization that human relevance must be at the forefront of biomedical discoveries.
Regulating the indirect land use carbon emissions from biofuels imposes high hidden costs on fuel consumers
Farmers earn more profits when there is demand for corn for biofuel instead of for food only. This can lead some to convert grasslands and forests to cropland. This conversion, also called indirect land use change, can have large-scale environmental consequences, including releasing stored carbon into the atmosphere. To penalize the carbon emissions from this so-called indirect land use change, the USEPA and California Air Resources Board include an indirect land use change factor when considering the carbon savings with biofuels for their compliance with the federal Renewable Fuel Standard or California’s Low-Carbon Fuel Standard.
Decoding life under our waters to ensure species' survival
Four hundred million lines of text: that’s how much data is in a single gene-sequencing file when Scott Pavey’s team receives it. If you wanted to scan it manually, and generously assume it would take one second per line to look at, it would take you 12 and a half years of reading around the clock to get through it all.
Is sea spray losing its sparkle?
Atmospheric aerosols are tiny particles that scatter and absorb sunlight but also influence climate indirectly through their role in cloud formation. One of the largest sources of aerosols is sea spray which is produced over the world’s oceans. Understanding how these particles take up water from the atmosphere, their so-called hygroscopicity, is important because it determines how much sunlight they reflect and how well they can form clouds.
