A new framework to enable retailers to better position their products to consumers has been devised by Tamer Boyaci and Frank Huettner at ESMT Berlin together with Yalcin Akcay from Melbourne Business School.

Researchers have identified how the human brain is able to determine the properties of a particular object using purely statistical information: a result which suggests there is an 'inner pickpocket' in all of us.

Artificial intelligence was able to detect malignant lung nodules on low-dose chest computed tomography scans with a performance meeting or exceeding that of expert radiologists, reports a new study from Google and Northwestern Medicine.This deep-learning system provides an automated image evaluation system to enhance the accuracy of early lung cancer diagnosis that could lead to earlier treatment. Lung cancer is most common cause of cancer deaths in US and is harder to treat when diagnosed at advanced stages.

It's not exactly the set of TV's 'American Ninja Warrior,' but a tiny obstacle course for bacteria has shown researchers how E. coli changes its behavior to rapidly clear obstructions to food. The work by scientists at Carnegie Mellon University, the University of Pittsburgh and the Salk Institute for Biological Studies holds implications for not only biology and medicine, but also robotic search-and-rescue tactics.

Bhaskar Krishnamachari, a professor at the USC Viterbi School of Engineering, and Aditya Asgaonkar -- a recent undergraduate computer science alum at BITS Pilani, India who visited and worked with Krishnamachari at USC Viterbi over several months in 2018 -- believe they have found a way to make the buying and selling of digital goods less costly, more efficient, and less vulnerable to fraud. Their proposed solution involves blockchain, 'smart contracts,' and game theory.

A recent study finds that US government spending on military personnel has a positive impact on the nation's human capital -- essentially improving the American workforce. The study estimates the economic impact of this human capital improvement to be $89.8 billion for 2019 alone.

A new study in Journal of Applied Ecology equips scientists to more accurately predict whether, and when, a species will go extinct by being more realistic about how long it takes populations to establish each new generation.

Researchers have developed a new framework for deep neural networks that allows artificial intelligence (AI) systems to better learn new tasks while 'forgetting' less of what it has learned regarding previous tasks. The researchers have also demonstrated that using the framework to learn a new task can make the AI better at performing previous tasks, a phenomenon called backward transfer.
