| 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. |
| Filter membrane renders viruses harmless Posted: 03 Jun 2021 02:13 PM PDT Researchers are developing a new filter membrane that is highly efficient at filtering and inactivating a wide variety of air-borne and water-borne viruses. |
| 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. |
| Mockingbirds follow similar musical rules as those found in human music Posted: 03 Jun 2021 02:11 PM PDT Mockingbirds follow similar musical rules as those found in human music, from Beethoven to Kendrick Lamar. |
| North Atlantic right whales have gotten smaller since the 1980s Posted: 03 Jun 2021 02:11 PM PDT Whales are largely protected from direct catch, but many populations' numbers still remain far below what they once were. A study suggests that, in addition to smaller population sizes, those whales that survive are struggling. As evidence, they find that right whales living in the North Atlantic today are significantly shorter than those born 30 to 40 years ago. |
| 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. |
| Puppies are wired to communicate with people Posted: 03 Jun 2021 08:19 AM PDT Dogs may have earned the title 'man's best friend' because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study suggests. |
| 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. |
| Coastal flooding increases Bay Area traffic delays and accidents Posted: 03 Jun 2021 08:19 AM PDT Disruptions from sea-level rise and coastal flooding events have significant indirect impacts on urban traffic networks and road safety. |
| How leafbirds make complex color-producing crystals Posted: 03 Jun 2021 08:19 AM PDT A recent study has discovered a novel way to manufacture single gyroid photonic crystals to work in the visible light spectrum, based on the self-assembly mechanism found in blue-winged leafbirds. |
| Beneficial arthropods find winter sanctuary in uncultivated field edges, study finds Posted: 03 Jun 2021 05:35 AM PDT A new study reveals that beetles, wasps and other beneficial arthropods are nearly twice as abundant and diverse in uncultivated field edges in the spring as they are in areas that are cropped - if those field edges are rich in an array of flowers and other broad-leaved plants and not just mowed grass. |
| Declining fish biodiversity poses risks for human nutrition Posted: 02 Jun 2021 02:06 PM PDT All fish are not created equal, at least when it comes to nutritional benefits. This truth has important implications for how declining fish biodiversity can affect human nutrition, according to a computer modeling study. |
| 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. |
| Record-breaking temperatures more likely in populated tropics Posted: 02 Jun 2021 02:06 PM PDT New research shows that most extreme heat events are going to occur in the tropics rather than the poles. |
| Zika virus RNA found in free-ranging African bats Posted: 02 Jun 2021 12:34 PM PDT Scientists have detected Zika virus RNA in free-ranging African bats. RNA, or ribonucleic acid, is a molecule that plays a central role in the function of genes. |
| 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. |
