URBANA, Ill. – Plants are designed to travel. They might not stand up and walk, but many plants produce seeds or other bits that can be carried long distances by wind or animals and start growing. While that might be great news for the plant, escapes like these can disrupt natural ecosystems and be costly to remove.

But just how costly?

URBANA, Ill. – Chronic wasting disease, the prion disease affecting white-tailed deer and other cervids, is spreading. With documented cases in 29 U.S. states, two Canadian provinces, three Scandinavian countries, and South Korea, free-ranging and captive cervids are under threat. Efforts to conserve endangered deer against this backdrop are understandably fraught.

URBANA, Ill. – Decades of corn breeding efforts emphasizing yield have contributed to modern hybrids with shallower and less complex root systems than their predecessors. Because the breeding and selection of most modern hybrids has taken place in environments with high nutrient concentrations, optimal weed control, and soil moisture conditions, hybrids perform best under high input systems.

URBANA, Ill. – Last month, the U.S. Agency for International Development (USAID) announced a new $30 million investment in the Soybean Innovation Lab (SIL) at the University of Illinois. The competitive grant was awarded under Feed the Future, the U.S. government’s global hunger and food security initiative led by USAID. 

URBANA, Ill. – What happens belowground in a corn field is easy to overlook, but corn root architecture can play an important role in water and nutrient acquisition, affecting drought tolerance, water use efficiency, and sustainability. If breeders could encourage corn roots to grow down at a steeper angle, the crop could potentially access important resources deeper in the soil.

What’s small and smart and worn all over?

It’s not a riddle, but a list of attributes envisioned by Nancy McElwain, a professor of human development and family studies at the University of Illinois Urbana-Champaign, as she searched for a data collection tool compatible with her youngest research participants.

URBANA, Ill. – Nitrous oxide may be much less abundant in the atmosphere than carbon dioxide, but as a greenhouse gas, it’s a doozy. With a potency 300 times greater than CO2, nitrous oxide’s warming potential, especially via agriculture, demands attention.

URBANA, Ill. – Humans aren’t the only ones suffering through unprecedented heatwaves in a warming climate. Consider the humble minnow. These tiny fish represent the all-important base of the food chain in many freshwater ecosystems. And like all fish, minnows adjust their body temperature to match their surroundings. As climate change turns up the heat, could minnows cook?

CHAMPAIGN, Ill. — For the first time, RIPE researchers have proven that multigene bioengineering of photosynthesis increases the yield of a major food crop in field trials. After more than a decade of working toward this goal, a collaborative team led by the University of Illinois has transgenically altered soybean plants to increase the efficiency of photosynthesis, resulting in greater yields without loss of quality.

In a new study, retired Illinois State Water Survey engineer Sally McConkey and Eric R. Larson, a professor of natural resources and environmental sciences at the U. of I., examined the metrics used at a county scale for national assessments to determine whether communities are prepared to withstand and recover from natural disasters such as floods and fires. McConkey spoke to News Bureau life sciences editor Diana Yates about what they found.
