| Genetic legacy of last glaciation influences reindeer's seasonal migrations Posted: 10 Feb 2022 12:42 PM PST Caribou (known as reindeer in Europe) make one of the longest seasonal migrations of land animals, but an individual's propensity to migrate depends on its genetic ancestry, researchers report. |
| Seawater seep may be speeding glacier melt, sea level rise Posted: 10 Feb 2022 12:41 PM PST A new study projects that warm seawater seeping under certain glaciers could eventually lead to future sea level rise that's double that of existing estimates. |
| Posted: 10 Feb 2022 09:58 AM PST Researchers have discovered a new clue in the search for the origin of life by showing that peptides can form on dust under conditions such as those prevailing in outer space. These molecules, which are one of the basic building blocks of all life, may therefore not have originated on our planet at all, but possibly in cosmic molecular clouds. |
| African Heritage Sites threatened by coastal flooding and erosion as sea-level rise accelerates Posted: 10 Feb 2022 08:40 AM PST Climate risk and heritage experts have provided the first comprehensive assessment of exposure of African cultural and natural Heritage Sites to extreme sea levels and erosion associated with accelerating sea level rise. |
| Climate drove 7,000 years of dietary changes in the Central Andes Posted: 09 Feb 2022 12:49 PM PST What a person eats influences a person's health, longevity and experience in the world. Identifying the factors that determine people's diets is important to answer the bigger questions, such as how changing climates will influence unequal access to preferred foods. A new study provides a blueprint to systematically untangle and evaluate the power of both climate and population size on the varied diets across a region in the past. |
| A century later, researchers describe second opabiniid ever discovered Posted: 08 Feb 2022 04:17 PM PST An international team of researchers confirm that a specimen previously considered a radiodont is in fact an opabiniid. The new study used novel and robust phylogenetic methods to confirm Utaurora comosa as only the second opabiniid ever discovered and the first in over a century. |
| Mineral dating reveals new clues about important tectonic process Posted: 08 Feb 2022 07:52 AM PST Ancient rocks on the coast of Oman that were once driven deep down toward Earth's mantle may reveal new insights into subduction, an important tectonic process that fuels volcanoes and creates continents, according to a new study. |
