Big data and technology in disasters: Better integration needed for effective response

Disasters are becoming more commonplace and complex, and the challenges for rescue and humanitarian organizations increase. Increasingly these groups turn to big data to help provide solutions. Researchers wished to examine how ICT tools and big data were being used in disaster responses. By conducting a structured literature search and developing a data extraction tool on the use of ICT and big data during disasters they showed that some important gaps exist which should be part of a future research focus.

Found: A destructive mechanism that blocks the brain from knowing when to stop eating

Researchers have uncovered a destructive mechanism at the molecular level that causes a well-known phenomenon associated with obesity: leptin resistance. They found that mice fed a high-fat diet produce an enzyme named MMP-2 that clips receptors for the hormone leptin from the surface of neuronal cells in the hypothalamus. This blocks leptin from binding to its receptors. This in turn keeps the neurons from signaling that your stomach is full and you should stop eating.
