High-tech future early warning system for hurricanes, tornados and volcanic eruptions

Posted by External 14 hours ago General
https://www.sciencedaily.com — The Laser Interferometer Gravitational-Wave Observatory (LIGO) has been able to detect a gravity wave wafting through space from two colliding black holes billions of years ago. Now a group has built a much smaller ring laser interferometer to explore how it could detect geophysical effects such as earthquake-generated ground rotation and infrasound from convective storms and have demonstrated th Read More

Environmental DNA provides early detection of invasive crayfish

Posted by External 4 days ago General
https://www.sciencedaily.com — Every plant and animal has a unique genetic composition, which makes a lake like a bowl of DNA soup—every spoonful contains the combined DNA of the lake’s inhabitants. Scientists have only recently begun using this environmental DNA, or eDNA, to identify the presence of organisms like amphibians and fish. A researcher and his colleagues analyzed eDNA to successfully detect the presence of the hig Read More

Oxygen levels were key to early animal evolution, strongest evidence now shows

Posted by External 4 days ago General
https://www.sciencedaily.com — It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago.

'Ecosystem canaries' provide early warning signs of catastrophic changes to ecosystems

Posted by External 40 days ago General
https://www.sciencedaily.com — 'Ecosystem canaries' can provide early warning signals of large, potentially catastrophic, changes or tipping points in ecosystems, say researchers. Like canaries that coal miners used to check for poisonous gasses deep underground, ‘ecosystem canaries’ are species that are often the first to disappear from a stressed ecosystem. Their vanishing can be linked to changes in the functioning of ecosy Read More

Population boom preceded early farming

Posted by External 55 days ago General
https://www.sciencedaily.com — Anthropologists have counted the number of carbon-dated artifacts at archaeological sites and concluded that a population boom and scarce food explain why people in eastern North America domesticated plants for the first time on the continent about 5,000 years ago.

Early snowmelt reduces forests' atmospheric carbon dioxide uptake, decreases streamflow volume

Posted by External 56 days ago General
https://www.sciencedaily.com — Earlier, slower snowmelt hinders a subalpine forest's ability to regulate atmospheric carbon dioxide and reduces streamflow, a phenomenon with potentially drastic consequences for agriculture, municipal water supplies and recreational opportunities in Colorado and the western US, say scientists.
