  • Atmospheric sciences professor Atul Jain and graduate student Prasanth Meiyappan found that most carbon emissions models overestimate the capacity of regrowing forests to take in carbon. Despite a projected abundance of photosynthesis-fueling carbon, nitrogen is limited, thus limiting forests' growth.

    Study shows new forests cannot take in as much carbon as predicted

    As carbon emissions continue to rise, scientists project forests will grow faster and larger, due to an increase in atmospheric carbon dioxide, which fuels photosynthesis. But a new study by researchers at the University of Illinois at Urbana-Champaign and the University of Bristol in the United Kingdom finds that these projections are overestimated.

  • Scientists are exploring the structural and chemical characteristics of cicada wings.

    Study reveals unique physical, chemical properties of cicada wings

    Biological structures sometimes have unique features that engineers would like to copy. For example, many types of insect wings shed water, kill microbes, reflect light in unusual ways and are self-cleaning. While researchers have dissected the physical characteristics that likely contribute to such traits, a new study reveals that the chemical compounds that coat cicada wings also contribute to their ability to repel water and kill microbes.

    Study recalculates cost of combination vaccines

    CHAMPAIGN, Ill. - One of the most popular vaccine brands for children may not be the most cost-effective choice. And doctors may be overlooking some cost factors when choosing vaccines, driving the market toward what is actually a more expensive option, according to a new study by University of Illinois researchers.

    Study: 'Legacy' phosphorus delays water quality improvements in Gulf of Mexico

    The same phosphorous that fertilizes the thriving agriculture of the Midwest is also responsible for a vast “dead zone” in the Gulf of Mexico near the Mississippi Delta. Efforts to reduce the amount of phosphorus that enters the Mississippi River system are underway, but research led by the University of Illinois Urbana-Champaign suggests that remnants of the contaminant are left behind in riverbeds for years after introduction and pose an overlooked – and lingering – problem.  

  • Yan Li and his colleagues found that a massive wind and solar installation in the Sahara Desert could have beneficial climatic and ecological effects.

    Study: Large-scale wind and solar farms in the Sahara would increase heat, rain, vegetation

    Wind and solar farms are known to have local effects on heat, humidity and other factors that may be beneficial – or detrimental – to the regions in which they are situated. A new climate-modeling study finds that a massive wind and solar installation in the Sahara Desert and neighboring Sahel would increase local temperature, precipitation and vegetation. Overall, the researchers report, the effects would likely benefit the region.

    A geologist, a microscopist and a doctor walk into a lab and, with their colleagues from across the nation, make a discovery that overturns centuries of thought about the nature and composition of kidney stones. The team’s key insight, reported in the journal Scientific Reports, is that kidney stones are built up in calcium-rich layers that resemble other mineralizations in nature, such as those forming coral reefs or arising in hot springs, Roman aqueducts or subsurface oil fields.

  • Atul Jain led a study that used a combination of satellite and census data to identify deforestation and expanding saltwater farming as the key physical and socioeconomic drivers of climate change in Bangladesh.

    Study: Integrating satellite and socioeconomic data to improve climate change policy

    Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding this relationship can inform climate policy at the national scale in Bangladesh and beyond.

    Study: Fire hastens permafrost collapse in Arctic Alaska

    While climate change is the primary driver of permafrost degradation in Arctic Alaska, a new analysis of 70 years of data reveals that tundra fires are accelerating that decline, contributing disproportionately to a phenomenon known as “thermokarst,” the abrupt collapse of ice-rich permafrost as a result of thawing.

  • In many developing countries, food is cooked over traditional biomass-burning cookstoves. Illinois researchers found that how users operate their stoves has a big effect on emissions.

    Study finds emissions from widely used cookstoves vary with use

    CHAMPAIGN, Ill. - The smoke rising from a cookstove fills the air with the tantalizing aroma of dinner - and a cloud of pollutants and particles that threaten both health and the environment. How families in developing countries use their cookstoves has a big effect on emissions from those stoves, and laboratory emission tests don't accurately reflect real-world operations, according to a study by University of Illinois researchers.
