Published Short X-ray pulses reveal the source of light-induced ferroelectricity in SrTiO3
(via sciencedaily.com) Original source Researchers have gained new insights into the development of the light-induced ferroelectric state in SrTiO3. They exposed the material to mid-infrared and terahertz frequency laser pulses and found that the fluctuations of its atomic positions are reduced under these conditions. This may explain why the dipolar structure is more ordered than in equilibrium and why the laser pulses induce a ferroelectric state in the material.
Published Climate change threatens older elephants most, jeopardizing African elephants' future
(via sciencedaily.com) Original source A collaborative team of researchers has conducted first-of-its kind research into how global climate change affects African elephants. The work shows that older elephants will have markedly decreased chances of survival, which will not only drastically reduce the species' overall ability to weather the changing climate but will send ripple effects throughout the surrounding landscape. The team has also modeled possible mitigation scenarios.
