Renewable Energy: The Power of Salt

August 26, 2014 4:27 pm | by Jennifer Chu, MIT | News | Comments

Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT. The researchers evaluated an emerging method of power generation called pressure retarded osmosis, in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane.

Visual Control of Big Data: Recomputing Visualizations without Aberrant Results

August 20, 2014 10:44 am | by Larry Hardesty, MIT | News | Comments

In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?

New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions, but never before observed, are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead make their presence known by lowering the temperature at which other baryons "freeze out"
