A team of university researchers has devised the first automated techniques to identify ads potentially tied to human trafficking rings and link them to public information from Bitcoin -- the primary payment method for online sex ads. They found they could identify groups of ads with a common author. They then tested an automated system that utilizes publicly available information from the Bitcoin mempool and blockchain to find connections between ads.

Small formats like Save-A-Lot and Aldi and neighborhood stores like Target Express have been growing recently in popularity in the US and around the world. For brands, the limited assortments mean greater competition for shelf-space, raising the question of whether it is worth expending marketing effort and slotting allowances to get on to their shelves. According to a forthcoming study in a leading INFORMS scholarly marketing journal, Marketing Science, the answer is 'yes.'

A 'Frankenstein's monster' dinosaur may be the missing link between two major dinosaur groups, plugging what was previously a big gap between them.

It seems like such a simple question: Do patients whose tumors shrink more in response to targeted treatment go on to have better outcomes than patients whose tumors shrink less? But the implications of a recent study demonstrating this relationship are anything but simple and could influence both the design of future clinical trials and the goals of oncologists treating cancer.

Scientists from ITMO University and Tampere University of Technology managed to improve computational imaging of optical signal in lensless microscopes. By employing special algorithms they increased the resolution of obtained images without any changes in the technical characteristics of microscopes.

Principal Scientist of VTT Technical Research Centre of Finland, Dr. Lasse Makkonen has explained the frictional mechanism that resists the motion of drops on inclined surfaces and when affected by wind drag, and developed a theory by which sliding of drops off surfaces of different materials can be predicted. This makes it possible to systematically develop hydrophobic surfaces by modifying their base material and roughness.
