SLAC researchers studying laser-driven proton acceleration introduced a self-replenishing water sheet target to address the inefficiency of replacing targets after each laser pulse. The new target had an unanticipated side effect, resulting in a naturally focused, more tightly aligned proton beam.
Italy’s Phlegraean Fields is a hotspot of volcanic activity — an ever-shifting landscape pocketed with acidic hot springs. This huge caldera is a part of the Campanian volcanic arc, which includes Mount Vesuvius, whose eruption wiped out the Roman city of Pompeii in 79 C.E. Yet, despite the hostile and scalding conditions of this environment, some microorganisms thrive. And researchers at Michigan State University are taking notice, hoping to uncover new information about how a particular alga survives in such extreme conditions.
In a new paper published in Plant Physiology, researchers in the MSU-DOE Plant Research Laboratory and the Walker lab — in collaboration with the Shachar-Hill lab of the Department of Plant Biology — are studying Cyanidioschyzon merolae, or C. merolae, and its unique ability to photosynthesize its own food. Understanding how C. merolae operates in such extreme conditions can help scientists better extrapolate — or improve upon — the process of photosynthesis, a function vital to all life on Earth.
MIT researchers developed an automated system to help programmers increase the efficiency of their deep learning algorithms by simultaneously leveraging two types of redundancy in complex data structures: sparsity and symmetry.
