The first all-female class has gradu- ated from the Spokane, Washington, based program that trains people to work in construction, Head Start to the Construction Trades. The seven women spent six weeks learning about carpentry, plumbing, welding and ironwork, plus they received OSHA, Forklift, First Aid and CPR certifications. Plans are underway to hold the next all-female class in February, sponsored by the Inland Northwest Associated General Contractors. http://facebook.com/headstarttotheconstructiontrades 18 LC DBM Research from the University of Konstanz in Germany were inspired by the structure of sea urchin spines to create a stronger cement. By building a polymeric binder into the cement, the energy from a fracture is absorbed rather than causing a crack in the concrete. The scientists report that a pillar made of their cement could be built nearly 5 miles high before collapsing – ten times as tall as the Burj Khalifa, which measures up at just over half a mile. https://tinyurl.com/y8rvc5qq The New York state departments of Agriculture and Markets, and Environmental Conservation have confirmed the presence of emerald ash borer in New York City. The pest has been present in Upstate New York for some time and has only recently infiltrated the city. Mark Whitmore, forestry expert at Cornell Cooperative Extension, offered advice to slow the spread of the pest. Don't move firewood, as this can move the pest faster than it can move on its own. Treat ash trees with systemic insecti - cides. Ash trees do not have nectar, so this will not harm bees. Infested trees can lose tensile strength and fall down, threatening public safety. www.emeraldashborer.info Twenty-five students completed horticulture degrees or certifi - cates at College of DuPage in the 2016-17 school year. Approxi- mately 280 students are enrolled in the program. Enrollment is steadily increasing, with fall 2017 enrollment up 8 percent from 2016, and 2016 up 27 percent from 2015. Nineteen students competed in the National Collegiate Landscape Competition, placing 22nd out of 60 colleges and universities. College of DuPage was the 5th highest placing commu - nity college. Three horticulture students competed in the Hardscape North America Installer Championship October 19 and 20, 2017. College of DuPage qualified for this event after placing second in the Hardscape Competition at the National Collegiate Landscape Competition. Additionally, College of DuPage was the winner of the 2016- 17 Come Alive Outside Design Challenge, bringing students together with landscape professionals to design and build engaging outdoor learning environments. The college placed first in the Illinois Landscape Contractors Association Design Contest in the hand-drawn, CAD, and 3-D Movie categories.

Blake Bernstein, a sports turf management major at Mount San Antonio College in Walnut, California, and winner of Toro's 2018 Super Bowl Sports Turfgrass Training Program, will travel to Minneapolis, Minnesota, to assist the grounds crew in field preparations for Super Bowl LII in Feb - ruary 2018. Bernstein will work alongside NFL field director Ed Mangan, groundskeeper George Toma, and the Super Bowl grounds crew at U.S. Bank Stadium on turfgrass maintenance, logo painting, field preparation for media day, halftime prepara - tion and field clean-up. https://tinyurl.com/ yadaxxw6 If neonicotinoid pesticides, the most common of which are clothianidin, imidacloprid, and thiamethoxam, are applied properly to flower - ing crops, they pose no threat to honeybee hives, according to analysis of more than 230 studies by scientists from the University of Guelph in Canada, though they acknowledge that individual bees are still at risk. The researchers hope to fur - ther examine the impacts that neonicotinoids and other pesticides have on hives, as most studies tend to empha - size individual bees instead of the colony as a whole. http://tinyurl. com/y8uo27u2 Building Better Cement with Biomimicry Emerald Ash Borer Found in New York City College of DuPage, Glen Ellyn, Illinois Turfgrass Student Is Going to the Super Bowl When Used Properly, Neonics Don't Harm Honeybee Colonies Head Start to the Construction Trades Program Graduates First All-Female Class
