The wisdom of crowds: What smart cities can learn from a dead ox and live fish

(Portland State University) Antonie J. Jetter, associate professor of Engineering and Technology Management at Portland State University, studied the wisdom of crowds theory. Jetter found diverse crowds of local natural resource stakeholders can collectively produce complex environmental models very similar to those of trained experts. “I am excited about the possibilities for other complex systems,” Jetter said.

Study weighs deep-sea mining’s impact on microbes

(Bigelow Laboratory for Ocean Sciences) The essential roles that microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new paper in Limnology and Oceanography reports. The study reviews what is known about microbes in these environments and assesses how mining could impact their important environmental roles.

InDepth Pharmaceuticals moves ahead with diagnostic to predict kidney transplant success

(Medical University of South Carolina) Charleston-based InDepth Pharmaceuticals has executed an option agreement with the Medical University of South Carolina Foundation for Research Development to evaluate and potentially commercialize a diagnostic tool to predict kidney transplant success in patients with focal segmental glomerulosclerosis (FSGS). The tool will identify those with recurrent FSGS, in whom transplanted kidneys are almost certain to fail, and possibly spare these patients the burden of a kidney transplant while preventing loss of valuable kidneys.

Memory boost with just one look

(HRL Laboratories) HRL Laboratories, LLC, researchers have published results showing that targeted transcranial electrical stimulation during slow-wave sleep can improve metamemories of specific episodes by 20% after only one viewing of the episode, compared to controls. The same technology may offer a non-invasive treatment to mitigate bad memories that might cause post-traumatic stress disorder (PTSD). Metamemory describes the sensitivity of whether memories are recalled accurately or not, such as during eyewitness testimony.

Who’s liable? The AV or the human driver?

(Columbia University School of Engineering and Applied Science) Researchers at Columbia Engineering and Columbia Law School have developed a joint fault-based liability rule that can be used to regulate both self-driving car manufacturers and human drivers. They propose a game-theoretic model that describes the strategic interactions among the law maker, the self-driving car manufacturer, the self-driving car, and human drivers, and examine how, as the market penetration of AVs increases, the liability rule should evolve.

University of Ottawa tool to democratize nanopore research

(University of Ottawa) A team of researchers at the University of Ottawa is democratizing entry into the field of nanopore research by offering up a unique tool to accelerate the development of new applications and discoveries. The innovative T.-Cossa Lab came up with the idea to provide the research community with the protocols, hardware designs, and software required to fabricate solid-state nanopores in a fast, low cost, and completely automated fashion. This method is available in Nature Protocols.
