| New technique unlocks ancient history of Earth from grains of sand Posted: 01 Mar 2022 10:11 AM PST Researchers have developed a new technique by studying the age of ancient grains of sand from beaches, rivers and rocks from around the world to reveal previously hidden details of the Earth's distant geological past. |
| Bacteria genes gave ancient plants traits to colonize land Posted: 01 Mar 2022 10:10 AM PST Genes jumping from microbes to green algae hundreds of millions of years ago might have driven the evolution of land plants, researchers report. Their analysis reveals that hundreds of genes from bacteria, fungi, and viruses have been integrated into plants, giving them desirable traits for a terrestrial life. |
| Social networking for fossils shows community impacts of mass extinctions Posted: 28 Feb 2022 07:38 AM PST By applying an algorithm akin to what social media sites use to make friend suggestions, researchers have identified communities of ancient life in the fossil record and tracked how their numbers changed through each of the planet's mass extinctions. |
| Mystery solved about the origin of the 30,000-year-old Venus of Willendorf Posted: 28 Feb 2022 06:55 AM PST The almost 11 cm high figurine from Willendorf is one of the most important examples of early art in Europe. It is made of a rock called 'oolite' which is not found in or around Willendorf. Anthropologist, geologists and prehistorians have now found out, with the help of high-resolution tomographic images, that the material from which the Venus was carved likely comes from northern Italy. This sheds new light on the remarkable mobility of the first modern humans south and north of the Alps. |
| Seismic study reveals key reason why Patagonia is rising as glaciers melt Posted: 28 Feb 2022 06:11 AM PST Geologists have discovered a link between recent ice mass loss, rapid rock uplift and a gap between tectonic plates that underlie Patagonia. |
| New DNA modification system discovered in animals, captured from bacteria more than 60 MYA Posted: 28 Feb 2022 06:11 AM PST In humans and other eukaryotes, two principal epigenetic marks are known. A team has discovered a third, novel epigenetic mark -- one formerly known only in bacteria -- in bdelloid rotifers, small freshwater animals. Epigenetic marks are modifications to DNA bases that don't change the underlying genetic code, but 'write' extra information on top of it that can be inherited along with your genome. |
| Hidden weaknesses within volcanoes may cause volcano collapse Posted: 25 Feb 2022 05:58 AM PST Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard. An international team of researchers has analyzed summit dome instabilities at Merapi Volcano, Indonesia. The researchers hope that by understanding the inner processes, volcano collapses can be better forecasted. |
