Physics graduate students Erik Bauch and Georg Kucsko have developed an online tool, Open Rev., for collaborative annotation of scientific publications.Open Rev. enables open discussion about scholarly works, independent of publishers, on a free platform that is easily accessible. Users can upload a paper, highlight specific sections and generate related questions, which are then open for response and discussion among the user community.Bauch and Kucsko have been testing, assessing and refining Open Rev. this past year with funds awarded through the HILT Spark Grant Program, intended to “spark” promising teaching and learning projects from idea to reality. In addition to this award, they also received the second prize at the 2013 – 2014 BRIDGE @ HGSE Education Innovation Pitch Competition, where teams of Harvard students and alumni present innovative solutions to current problems in education.Open Rev. currently has 400 users and over 1000 public domain comments. Students and instructors have used the tool within several physics courses last semester in class discussion and to share lecture notes. All faculty, students and staff are encouraged to try the new platform this coming semester. For more information, assistance setting up groups, and/or learning more about the features, please contact the Open Rev. team at [email protected] Read Full Story

Under a deal brokered by Gov. J.B. Pritzker’s administration, the Texas-based owner of eight coal-fired power plants in central and southern Illinois agreed last week to shutter 40% of its fleet by the end of the year.Vistra Energy will be allowed to choose which units it retires and might scrap some of its cleaner power plants instead of the dirtiest. But the company’s agreement with the state’s new Democratic governor is far more stringent than industry-friendly rules proposed two years ago by former Republican Gov. Bruce Rauner.Rauner’s plan would have allowed Vistra to dramatically increase its emissions of lung-damaging and climate-changing pollution. Instead, the state-imposed limits brokered by the Pritzker administration are slightly higher than the fleet’s emissions during the past five years and will become more restrictive every time a coal plant closes for good.The agreement is another sign that Illinois, like many other states, isn’t turning back from a steady shift to cleaner sources of electricity, despite Trump’s move last week to gut national climate pollution standards adopted by former President Barack Obama. It appears the only question is whether Trump’s latest rollback of environmental regulations will enable some coal-fired power plants to keep running longer than expected, slowing the transition to wind, solar and other forms of clean energy that are quickly becoming less expensive than coal.Vistra became Illinois’ largest producer of coal-fired electricity last year when it acquired eight power plants in a merger with Dynegy, another Texas-based company. Even before the deal was finalized, Vistra executives hinted they might end up scrapping the entire Illinois fleet because the aging coal plants struggle to compete in energy markets.Another sign that coal is still on the way out in Illinois: Vistra is pushing legislation in Springfield that would require downstate ratepayers to subsidize the company’s proposed shift to solar power on the sites of its shuttered coal plants. Lawmakers remain skeptical. The company’s proposal failed to gain traction during the recently completed legislative session.More: Illinois is moving away from coal, despite Trump bailout of struggling industry Illinois deal with Vistra will close 2GW of coal capacity in the state by year’s end
