For Disruption, MOOCs Beat Open-Access Journals, Scholar Says
MOOCs are more disruptive to higher education than open-access megajournals are, in part because of structural protections in the scholarly-publishing world and because some policy makers are pushing massive open online courses as a means to increase productivity, a professor argues in a new article on open-access alternatives in higher education.

Open Source Machine Learning Tool Could Help Choose Cancer Drugs
The selection of a first-line chemotherapy drug to treat many types of cancer is often a clear-cut decision governed by standard-of-care protocols, but what drug should be used next if the first one fails? That's where Georgia Institute of Technology researchers believe their new open source decision support tool could come in. Using machine learning to analyze RNA expression tied to information about patient outcomes with specific drugs, the open source tool could help clinicians chose the chemotherapy drug most likely to attack the disease in individual patients. In a study using RNA analysis data from 152 patient records, the system predicted the chemotherapy drug that had provided the best outcome 80 percent of the time.

Rice U. Lab Creates Open-Source Optogenetics Hardware, Software
Nobody likes a cheater, but Rice University bioengineering graduate student Karl Gerhardt wants people to copy his answers. That’s the whole point. Gerhardt and Rice colleagues have created the first low-cost, easy-to-use optogenetics hardware platform that biologists who have little or no training in engineering or software design can use to incorporate optogenetics testing in their labs. Rice’s Light Plate Apparatus (LPA) is described in a paper available for free online this week in the open-access journal Scientific Reports...

Robot-Like Machines Helped People With Spinal Injuries Regain Function
Scientists with the international scientific collaboration known as the "Walk Again Project" use noninvasive brain-machine interfaces in their efforts to reawaken damaged fibers in the spinal cord. Researchers in Brazil who are trying to help people with spine injuries gain mobility have made a surprising discovery: Injured people doing brain training while interacting with robot-like machines were able to regain some sensation and movement...
