(Botanical Society of America) The National Science Foundation recently provided funding to over 100 herbaria across the Southeast U.S. to digitize more than three million plant specimens collected by botanists and naturalists across the country. Researchers tracked the speed and productivity of staff and students who handled the specimens, from the collection drawers to online repositories, to provide institutions with a framework to better determine the time and money needed to digitize remaining collections.
A deep trough of low pressure spanned the Great Lakes. Behind it, a wall of cold air built and folded over itself, layer upon layer, until it was both towering and poised. Finally, it broke free to race east toward…
(Florida Museum of Natural History) Two fossil teeth from a distant relative of North American gophers have scientists rethinking how some mammals reached the Caribbean Islands.
(University of Vienna) Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which difficults the analyses to be performed with these sequences. A study led by Ron Pinhasi and Pere Gelabert of the University of Vienna and published in Current Biology successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years bp obtained from the cave of Satsurblia in the Caucasus (Georgia).
(University of Exeter) Evidence from an ancient eggshell has revealed important new information about the extreme climate change faced by human early ancestors.
(University of the Basque Country ) The UPV/EHU’s Vertebrate Palaeontology research group has described two new species of palaeotheriidae mammals that inhabited the subtropical landscape of Zambrana (Álava) about 37 million years ago. Their atypical dental features could point to a difference in environmental conditions between the Iberian and Central European areas.
Scientists determined a skull found in China is a new species named Homo longi, or Dragon Man, which is the closest relative to Homo sapiens.
The post Dragon Man may be Homo sapiensâ closest relative first appeared on EarthSky.
On July 1, 2021 pm, the MetOp-1 satellite recorded a mean methane level of 1935 ppb at 293 mb. This mean methane level translates into 387 ppm CO₂e at a 1-year Global Warming Potential (GWP) of 200. This GWP is…
