It appeared first in captive mule deer in Colorado in the late 1960s. By 1981, it had escaped to the wild. It reached the Midwest by 2002. Little is known about its potential to infect humans.Symposium marks milestones in honey bee management, researchDec 10, 2010 9:00 am856 views CHAMPAIGN, lll. - In 1851, Lorenzo Langstroth, a Congregational minister and young ladies' school principal based in Philadelphia, revolutionized the practice of beekeeping. He had observed that honey bees will fill a large space in their hives with honeycomb and seal small cracks with propolis, a resinous "bee glue" made from tree sap and other sticky substances, but will leave any gap that is about 3/8 of an inch wide - just big enough for a bee to pass through. Langstroth was the first to incorporate this "bee space," which allows bees to navigate through the hive, into the design of his box-frame hive.Symposium marks century of discovery for U. of I. entomology departmentDec 3, 2009 9:00 am41 views CHAMPAIGN, lll. - The University of Illinois department of entomology celebrates its 100th anniversary in 2009 and will mark this milestone with a symposium Dec. 11 - two days before the annual meeting of the Entomological Society of America in Indianapolis.Symposium marks 30th anniversary of discovery of third domain of lifeOct 16, 2007 9:00 am72 views CHAMPAIGN, Ill. - Thirty years ago this month, researchers at the University of Illinois published a discovery that challenged basic assumptions about the broadest classifications of life.

They analyzed RNA interference (RNAi), a method that uses genetic material to "silence" specific genes - in this case genes known to give insect pests an advantage. The researchers found that western corn rootworm beetles that are already resistant to crop rotation are in some cases also less vulnerable to RNAi.Substances in honey increase detoxification gene expression, team findsMay 1, 2013 9:00 am701 views CHAMPAIGN, lll. - Research in the wake of Colony Collapse Disorder, a mysterious malady afflicting (primarily commercial) honey bees, suggests that pests, pathogens and pesticides all play a role. New research indicates that the honey bee diet influences the bees' ability to withstand at least some of these assaults. Some components of the nectar and pollen grains bees collect to manufacture food to support the hive increase the expression of detoxification genes that help keep honey bees healthy.Study yields more than a million new cyclic compounds, some with pharmaceutical potentialMar 12, 2018 8:30 am737 views Researchers say they can now produce a vast library of unique cyclic compounds, some with the capacity to interrupt specific protein-protein interactions that play a role in disease.

The study used a driving simulator and videophone to assess how a driver's conversation partner influences safety on the road.Study supports new explanation of gender gaps in academiaJan 15, 2015 9:00 am131 views CHAMPAIGN, Ill. - It isn't that women don't want to work long hours or can't compete in highly selective fields, and it isn't that they are less analytical than men, researchers report in a study of gender gaps in academia. It appears instead that women are underrepresented in academic fields whose practitioners put a lot of emphasis on the importance of being brilliant - a quality many people assume women lack.Study suggests stress of task determines if estrogen helps cognitionAug 27, 2004 9:00 am38 views CHAMPAIGN, Ill. - Does estrogen help cognition? Many women ponder that question as a quality-of-life issue while deciding on estrogen therapy since it has been linked to potential disease complications. Now, a new study at the University of Illinois at Urbana-Champaign suggests that the stress of any given task at least partially determines if hormones will help the mind.Study suggests police officer wrongfully convicted for missing the 'obvious'Jun 9, 2011 9:00 am666 views CHAMPAIGN, lll. - In a new study, researchers tested the claims of a Boston police officer who said he ran past a brutal police beating without seeing it.
