26 LC DBM Starting in the fall of 2018, Pennsylvania College of Tech - nology, a Penn State affiliate, will be offering a two-year associate degree in concrete science technology. The pro - gram, reported to be the first of its kind on the East Coast, will offer courses in the production and evaluation of concrete as well as applications, aggregate selection, admixture techniques, and products specific to the concrete industry. https://www.pct.edu/ An Iowa State Univer- sity study looked at ge- netics to determine how plants regulate growth in drought conditions. The researchers crossbred plants to knock out three genes from the group that governs stress response, growth and bacterial response. While the modified plants showed lower than nor - mal growth, they were more drought tolerant than those that were left alone. The researchers plan to continue to study how growth, drought tolerance, and bacterial response interact to ultimately create plants better suited to withstand challenges of the day. www.iastate.edu According to researchers at North Carolina State University, wild bee species will decline as urban temperatures increase. A study of 15 common bee species showed adverse effects on the insects at high temperatures, with incapacitation occurring between 113 to 124°F depending on the species. https://www.ncsu.edu/ Pennsylvania School Offering Concrete Science Tech Degree Exploring How Plants Regulate Growth During Drought Research from the National University of Singapore indi - cates that some plants will selectively kill parts of their roots to better withstand the stress from cold weather and recover faster when tempera - tures rise again. By applying this knowledge, the researchers are hoping to engi - neer cold toler- ance in plants. http://news.nus. edu.sg/research A Different Way for Plants to Survive Winter Bees Suffer in the Heat Too A recent study from Stony Brook University, part of the State University of New York system, found that though cement kilns produce about 20 percent of industrial sulfur dioxide emissions, concrete in urban areas can absorb high levels of sulfur dioxide, one of the most common pollutants. The researchers cautioned that the capacity for concrete to absorb pollution diminishes as it ages, but crushing concrete to expose new surfac - es can restore some of the properties that remove pollutants. http://research. stonybrook.edu/ Concrete Absorbs Pollutants HCSS, a construction software company, will be awarding $50,000 in college scholarships to 17 students as part of their annual Intern of the Year awards. To be eligible, college students must have completed a 2-month or longer construction related internship during the 2016-2017 school year, including summer 2017. Students can apply at construc - tioninternawards.com . Heavy Construction Systems Specialists Offers Scholarships By exposing bees to artificial pollen with levels of neo - nicotinoids similar to what they would be exposed to in real life over the course of 12 weeks, researchers from York University in Canada concluded that honeybees exposed to the pesticide have their lifespans shortened by about 23 percent. Additionally, the research - ers found that exposure to the fungicide boscalid can make neonicotinoids twice as deadly to honeybees. www.yorku.ca Another Study Shows Neonics Harm Bees PHOTO COURTESY OF THE U.S. GEOLOGICAL SURVEY CREDIT: STEFAN LEFNAER, CC BY-SA 4.0, VIA WIKIMEDIA COMMONS
