New study uncovers 'magnetic' memory of European glass eels Posted: 17 Oct 2019 01:22 PM PDT A new study has found that European glass eels use their magnetic sense to 'imprint' a memory of the direction of water currents in the estuary where they become juveniles. |
Mapping global biodiversity change Posted: 17 Oct 2019 11:11 AM PDT A new study which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land. |
Stranded whales detected from space Posted: 17 Oct 2019 11:11 AM PDT A new technique for analysing satellite images may help scientists detect and count stranded whales from space. Researchers tested a new detection method using Very High Resolution (VHR) satellite images of the biggest mass stranding of baleen whales yet recorded. It is hoped that in the future the technique will lead to real-time information as stranding events happen. |
Posted: 17 Oct 2019 11:11 AM PDT Geophysicists complete their analysis of a well-documented seismic event that held many surprises. |
Phylogenetic analysis forces rethink of termite evolution Posted: 17 Oct 2019 11:10 AM PDT Despite their important ecological role as decomposers, termites are often overlooked in research. Evolutionary biologists have constructed a new family tree for this unassuming insect brood, shedding unexpected light on its evolutionary history. |
An evolution in the understanding of evolution Posted: 17 Oct 2019 10:57 AM PDT An engineering professor and her former Ph.D. student share a new, more accurate method for modeling evolutionary change. |
Museums put ancient DNA to work for wildlife Posted: 17 Oct 2019 10:22 AM PDT Scientists who are trying to save species at the brink of extinction are finding help in an unexpected place. Researchers increasingly are embracing the power of ancient DNA from old museum specimens to answer questions about climate change, habitat loss and other stresses on surviving populations. |
Industrial melanism linked to same gene in 3 moth species Posted: 17 Oct 2019 10:14 AM PDT The rise of dark forms of many species of moth in heavily polluted areas of 19th and 20th century Britain, known as industrial melanism, was a highly visible response to environmental change. But did the different species rely on the same gene to adapt? New research by the University of Liverpool reveals that three species of moth, including the famous peppered moth, indeed did. |
How aerosols affect our climate Posted: 17 Oct 2019 10:14 AM PDT Greenhouse gases may get more attention, but aerosols -- from car exhaust to volcanic eruptions -- also have a major impact on the Earth's climate. Using a massive NASA dataset, researchers have created a framework that helps explain just how sensitive local temperatures are to aerosols. |
Fingerprints of Earth's original building blocks discovered in diamond-bearing rocks Posted: 17 Oct 2019 09:52 AM PDT Scientists have detected primordial chemical signatures preserved within modern kimberlites, according to new research. The results provide critical insight for understanding the formation of Earth. |
