Stone Age raves to the beat of elk tooth rattles? Posted: 03 Jun 2021 02:13 PM PDT In the Stone Age, some 8,000 years ago, people danced often and in a psychedelic way. This is a conclusion drawn from elk teeth discovered in the Yuzhniy Oleniy Ostrov burial site in the Republic of Karelia, Russia, whose wear marks and location in the graves indicate that the objects were used as rattlers. |
Underwater ancient cypress forest offers clues to the past Posted: 03 Jun 2021 02:12 PM PDT Marine geologists and paleoclimatologists new research findings uncover new information about the underwater ancient cypress forest and the Gulf Coast's past. |
South Pole and East Antarctica warmer than previously thought during last ice age, two studies show Posted: 03 Jun 2021 02:11 PM PDT Glaciologists analyzed Antarctic ice cores to understand the continent's air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition. |
A shark mystery millions of years in the making Posted: 03 Jun 2021 02:11 PM PDT The biggest shark attack in history did not involve humans. A new study by earth scientists has turned up a massive die-off of sharks roughly 19 million years ago. It came at a period in history when there were more than 10 times more sharks patrolling the world's oceans than there are today. |
Five million years of climate change preserved in one place Posted: 03 Jun 2021 08:19 AM PDT An international team of researchers has now succeeded in reconstructing changes in rainfall in Central Asia over the past five million years. The information preserved within the sedimentary succession provides the missing link for understanding land-water feedbacks for global climate. |
Is Earth's core lopsided? Strange goings-on in our planet's interior Posted: 03 Jun 2021 08:19 AM PDT Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. Scientists created a core growth model to explain this. To fit seismic data, the model predicts that asymmetric growth of the core leads to crystal movement that preferentially aligns iron-nickel crystals north-south. The model implies that the core is only 0.5-1.5 billion years old, a fraction of Earth's age. |
Culture drives human evolution more than genetics Posted: 02 Jun 2021 02:06 PM PDT Researchers found that culture helps humans adapt to their environment and overcome challenges better and faster than genetics. Tim Waring and Zach Wood found that humans are experiencing a 'special evolutionary transition' in which the importance of culture is surpassing the value of genes as the primary driver of human evolution. Due to the group-orientated nature of culture, they also concluded that human evolution itself is becoming more group-oriented. |
Top acoustic amplifier emerges from 50-year-old hypothesis Posted: 02 Jun 2021 06:11 AM PDT Scientists have built the smallest and best acoustic amplifier. And they did it using a concept that was all but abandoned for almost 50 years. |
