Tropical crow species is highly skilled tool user Posted: 14 Sep 2016 10:59 AM PDT An international team of scientists and conservation experts has discovered that the critically-endangered Hawaiian crow is a highly proficient tool user.

Study links selfies, happiness Posted: 13 Sep 2016 02:34 PM PDT Regularly snapping selfies with your smartphone and sharing photos with your friends can help make you a happier person, according to computer scientists. In a first-of-its-kind study published just before back-to-school season, the authors found that students can combat the blues with some simple, deliberate actions on their mobile devices.

Pop science: Engineers stop soap bubbles from swirling Posted: 13 Sep 2016 02:33 PM PDT Engineers have happened upon a way to stop the movement of the colorful eddies on the surface of soap bubbles. The results are works of art that could lead to stable engineered foams for medical treatments, personal products and food.

Rare Roman gold coin found in Jerusalem at Mt. Zion archaeological dig Posted: 13 Sep 2016 12:05 PM PDT Though the Roman Empire occupied Jerusalem and certainly spread its currency there, the only known Roman coins from the ancient Jewish capital have all come to historians and archaeologists through collectors, with uncertain provenance. An exception is a gold coin recently discovered near excavations of wealthy first century priestly houses on Jerusalem's Mt. Zion. Dated to 56 CE, it may be an remnant of looting at the time of the city's destruction in 70 CE.

Tuning materials and devices to adapt to their environment Posted: 13 Sep 2016 09:45 AM PDT By leveraging molecular beam epitaxy deposition and high-quality materials with large dielectric constants, researchers pursue future radio-frequency materials and devices capable of being 'tuned' to adapt to changing environments.
