| Ice Man, Ötzi: A treacherous murder with links to Central Italy Posted: 23 Sep 2016 11:01 AM PDT The copper used to make Ötzi's axe blade did not come from the Alpine region as had previously been supposed, but from ore mined in southern Tuscany. Ötzi was probably not involved in working the metal himself, as the high levels of arsenic and copper found in his hair had, until now, led us to assume. His murder over 5,000 years ago seems to have been brought about due to a personal conflict a few days before his demise, and the man from the ice, despite his normal weight and active life-style, suffered from extensive vascular calcification. |
| Melatonin, biological clock keep singing fish on time Posted: 23 Sep 2016 09:26 AM PDT In the 1980s, people living on houseboats in the San Francisco Bay were puzzled by a droning hum of unknown origin that started abruptly in the late evening and stopped suddenly in the morning. A lengthy investigation revealed the culprit: male plainfin midshipman fish (Porichthys notatus) that sing at night to attract mates. The fish, which can grow to 15 inches in length, live along the Pacific coast from Alaska to Baja, California. |
| Posted: 22 Sep 2016 01:12 PM PDT Utah's iconic Rainbow Bridge hums with natural and human-made vibrations, according to a new study. The study characterizes the different ways the bridge vibrates and what frequencies and energy sources cause the rock structure to resonate. The vibrations are small, according to a geology and geophysics professor, but the study provides a baseline measure of the bridge's structural integrity and shows how human activities can rattle solid rock. |
