Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.

The researchers say their insights will help develop more sustainable agricultural practices.

CHAMPAIGN, Ill. - A new study analyzing the impact of hand-held cell phone legislation on driving safety concludes that usage-ban laws had more of an impact in densely populated urban areas with a higher number of licensed drivers than in rural areas where there are fewer licensed drivers, according to a University of Illinois researcher.

New, highly stretchable sensors can monitor and transmit plant growth information without human intervention, report University of Illinois Urbana-Champaign researchers in the journal Device. The polymer sensors are resilient to humidity and temperature, can stretch over 400% while remaining attached to a plant as it grows and send a wireless signal to a remote monitoring location, said chemical and biomolecular engineering professor Ying Diao, who led the study with plant biology professor and department head Andrew Leakey.

CHAMPAIGN, Ill. - The brown marmorated stink bug - scientific name Halyomorpha halys - has been found in four Illinois counties and could be a major threat to fruit, vegetable and agronomic crops if it proliferates.

Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these “overcompensators,” as they are called, also augment their defensive chemistry – think plant venom – when they are clipped.

CHAMPAIGN, Ill. - The Illinois Natural History Survey has received a grant from the Conservation 2000 Program to assess seed banks at the Midewin National Tallgrass Prairie in Will County.

CHAMPAIGN, Ill. - High corn prices are leading many growers to plant corn every year and to overuse pesticides and other bug-killing technology to maximize yields, researchers report. In many instances, pesticides are applied without scouting fields to see if they are needed, violating a bedrock principle of integrated pest management. The result is a biological diversity desert in many corn and soybean fields in the agricultural Midwest, and signs that the surviving insects are becoming resistant to several key bug-fighting tools now available to farmers.

CHAMPAIGN, Ill. - The decomposition of plant, animal and microbial material in soil and water produces a variety of complex organic molecules, collectively called natural organic matter. These compounds play many important roles in the environment.

Increased government investment in climate change mitigation is prompting agricultural sectors to find reliable methods for measuring their contribution to climate change. With that in mind, a team led by scientists at the University of Illinois Urbana-Champaign proposed a supercomputing solution to help measure individual farm field-level greenhouse gas emissions. Although locally tested in the Midwest, the new approach can be scaled up to national and global levels and help the industry grasp the best practices for reducing emissions.

A team of Midwestern climate scientists has released a new report with grim predictions about the impact of climate change on the Great Lakes region. The report foresees a growing trend of wetter winters and springs, with increases in heavy rain events leading to flooding, particularly in urban areas with hard surfaces that cannot absorb the excess water. Rural areas will likely see more erosion, and unpredictable cycles of heat and rainfall could undermine agriculture.

Monarch butterfly declines cannot be attributed merely to declines in milkweed abundance, researchers report.

Purple martins will soon migrate south for their usual wintertime retreat, but this time the birds will be wearing what look like little backpacks, as scientists plan to track their roosting sites along the way. The researchers recently discovered that purple martins are roosting in small forest patches as they migrate from North America to Brazil, an unexpected behavior. The scientists published their findings in the Journal of Field Ornithology. 

Weed scientists in at least two Midwestern states have been reporting for years that a conservation program meant to provide habitat for pollinating insects is sowing bad seeds – including seeds of the potentially devastating agricultural weed Palmer amaranth – along with the good. Now, researchers at the University of Illinois have traced the weed seeds to at least one source: pollinator habitat seed sold by a company in the Midwest.

CHAMPAIGN, Ill. — It took decades of painstaking work, but research geneticist Ram Singh managed to cross a popular soybean variety (“Dwight” Glycine max) with a related wild perennial plant that grows like a weed in Australia, producing the first fertile soybean plants that are resistant to soybean rust, soybean cyst nematode and other pathogens of soy.

By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the journal Nature Genetics, also open a new window on the complicated evolutionary history of grasses like sorghum and rice, which share a distant ancestor with pineapple.

A study of overweight dogs fed a reduced calorie, high-protein, high-fiber diet for 24 weeks found that the dogs’ body composition and inflammatory markers changed over time in ways that parallel the positive changes seen in humans on similar diets. The dogs achieved a healthier weight without losing too much muscle mass, and their serum triglycerides, insulin and inflammatory markers all decreased with weight loss.

CHAMPAIGN, Ill. - Size matters when it comes to meal portions in weight-loss diets, according to researchers at the University of Illinois at Urbana-Champaign. And consuming convenient, nutritious frozen dinners may be a way to control portion size.

Using a new algorithm, University of Illinois researchers may have found the solution to an age-old dilemma plaguing satellite imagery – whether to sacrifice high spatial resolution in the interest of generating images more frequently, or vice versa. The team’s new tool eliminates this trade-off by fusing high-resolution and high-frequency satellite data into one integrated product, and can generate 30-meter daily continuous images going back to the year 2000. 

Iron deficiency in the first four weeks of a piglet’s life – equivalent to roughly four months in a human infant – impairs the development of key brain structures, scientists report. The abnormalities remain even after weeks of iron supplementation begun later in life, the researchers found.

CHAMPAIGN, Ill. - According to the World Health Organization, more than two-thirds of Americans are overweight or obese. And it's not just humans who are packing on the pounds. Our furry companions are plagued by an obesity epidemic of their own. More than 50 percent of the dogs and cats in the United States are overweight or obese.

CHAMPAIGN, Ill. - The western corn rootworm beetle, a pest that feasts on corn roots and corn silk and costs growers more than $1 billion annually in the U.S., also can survive on the perennial grass Miscanthus x giganteus, a potential biofuels crop that would likely be grown alongside corn, researchers report.

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach, detailed in the journal Nature Communications, relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

University of Illinois engineers developed a model to calculate the age of nitrogen in corn and soybean fields, which could lead to improved fertilizer application techniques to promote crop growth while reducing leaching.
