URBANA, Ill. – For corn growers, the decision of when and how much nitrogen fertilizer to apply is a perennial challenge. Scientists at the University of Illinois have shown that nanosatellites known as CubeSats can detect nitrogen stress early in the season, potentially giving farmers a chance to plan in-season nitrogen fertilizer applications and alleviate nutrient stress for crops.

URBANA, Ill. – Fall-applied anhydrous ammonia may not fulfill as much of corn’s nitrogen needs as previously assumed. According to a new study from the University of Illinois, the effectiveness of the practice depends on the soil.

The study used a “tagged” form of ammonia to determine how much of the nitrogen in corn grain and plant material comes from fertilizer, versus nitrogen supplied naturally by the soil.

From mid-November 2015 through February 2016, scientists used GPS transmitters to track the movements of Canada geese near Midway International Airport in Chicago. They discovered that – in the colder months, at least – some geese are hanging out on rooftops, in a rail yard and in a canal close to Midway’s runways. This behavior increases the danger of collisions between geese and airplanes, the researchers say.

URBANA, Ill. – World leaders convened for the UN Climate Summit in September amid dire projections of climate instability. The problem is multifaceted, of course, but a recent IPCC report identifies deforestation as the main driver of land-based greenhouse gas emissions, which comprise almost a quarter of all human contributions to climate change. What if more people around the world could be paid to keep forests healthy and intact?

URBANA, Ill. – Given the alarming pace of climate change, it is increasingly important to understand what factors motivate people to take action – or not – on environmental issues. A recent study in Sustainability Science shows that deeply held values, which align closely with political leanings, can predict whether someone takes action to protect the environment. And it suggests people on opposite ends of the political spectrum can be spurred to take action, as long as messaging taps into those values.

URBANA, Ill. – Children are losing their connection to nature.

It’s more than an unfortunate abstraction. Scientists say our increasingly indoor lifestyle negatively affects our health and well-being, not to mention our drive to protect the natural world. And it may be hampering kids’ ability to learn and thrive. A new e-book, published by Frontiers in Psychology, examines the many ways putting children back in contact with nature could make them more successful in school and in life.

URBANA, Ill. – Invasive silver carp have been moving north toward the Great Lakes since their accidental release in the 1970s. The large filter-feeding fish, which are known to jump from the water and wallop anglers, threaten aquatic food webs as well as the $7 billion Great Lakes fishery. But, for the past decade, the invading front hasn’t moved past Kankakee. A new study, led by scientists at the University of Illinois, suggests that Chicago’s water pollution may be a contributing to this lack of upstream movement.

URBANA, Ill. – As modern societies become increasingly urban, sedentary, and screen-oriented, people are spending less time in nature. We’re also more likely than ever to suffer from mental illnesses. A new article in Science Advances links the two phenomena, suggesting that adding natural elements to urban landscapes could improve mental health.

URBANA, Ill. – When tornadoes touch down, we brace for news of property damage, injuries, and loss of life, but the high-speed wind storms wreak environmental havoc, too. They can cut through massive swaths of forest, destroying trees and wildlife habitat, and opening up opportunities for invasive species to gain ground.
