Study shows human ancestors could have consumed hard plant tissues without damaging their teeth
Study traces evolution of acoustic communication
Imagine taking a hike through a forest or a stroll through a zoo and not a sound fills the air, other than the occasional chirp from a cricket. No birds singing, no tigers roaring, no monkeys chattering, and no human voices, either. Acoustic communication among vertebrate animals is such a familiar experience that it seems impossible to imagine a world shrouded in silence. …read more

‘Melting rock’ models predict mechanical origins of earthquakes
Engineers at Duke University have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take place miles beneath the Earth’s surface under incredible pressures and temperatures, and could help researchers better predict earthquakes—or even, at least theoretically, attempt to stop them. …read more

ISSCR statement on ethical standards for stem cell-based embryo models
The ISSCR is updating its Guidelines for Stem Cell Research and Clinical Translation to respond to recent scientific advances that include the use of pluripotent stem cell (PSC) to create models of early human embryo development (see Stem Cell Reports 14:1-6). As the science continues to advance, it raises important scientific, clinical, ethical, and societal issues for researchers, regulators, and funding agencies. The ISSCR believes the scientific community must address these challenges to establish parameters for research in this area. …read more
