Secrets of the ‘lost crops’ revealed where bison roam
Blame it on the bison. If not for the wooly, boulder-sized beasts that once roamed North America in vast herds, ancient people might have looked past the little barley that grew under those thundering hooves. But the people soon came to rely on little barley and other small-seeded native plants as staple food.
New light on polar explorer’s last hours
Chemical analyzes of a black spot in a diary shed new light on the destiny and tragic death of legendary Inuit polar expedition member Jørgen Brønlund in Northeast Greenland in 1907.
Huge iceberg A-68A nears South Georgia Island
Scientists watch as A-68A, currently the planetâs largest iceberg, approaches a remote island in the southern Atlantic Ocean.
Antibiotic resistance surveillance tools in Puerto Rican watersheds after Hurricane Maria
Researchers have further developed an innovative antibiotic resistance surveillance approach by applying DNA sequencing techniques to detect the spread of disease in watersheds impacted by large-scale storms.
Fish carcasses deliver toxic mercury pollution to the deepest ocean trenches
The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world’s oceans, including the deepest spot of them all: the 36,000-foot-deep Mariana Trench in the northwest Pacific.
Distinct slab interfaces found within mantle transition zone
(Chinese Academy of Sciences Headquarters) Prof. CHEN Qifu’s group from the Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) and their collaborators observed two distinct seismic discontinuities within the mantle transition zone (~410 km to 660 km) beneath the western Pacific.
Tips for watching N. Taurid meteors
The nominal peak of the North Taurid meteor shower is on the night of November 11-12, 2020.
Population dynamics and the rise of empires in Inner Asia
Researchers seek to understand the genetic, sociopolitical and cultural changes surrounding the formation of the eastern Eurasian Steppe’s historic empires. The study analyzes genome-wide data for 214 ancient individuals spanning 6,000 years and discusses the genetic and cultural changes that preceded the rise of the Xiongnu and Mongol nomadic pastoralist empires.
Longer mud season, no snow could alter northeast US rivers by 2100
Researchers have found that snow cover is on the decline in northeastern US due to climate change and by the end of century, the vernal window, sometimes referred to as mud season, could be two to four weeks longer which means significantly less melting snow that could be detrimental to key spring conditions in rivers and surrounding ecosystems.
New drone technology improves ability to forecast volcanic eruptions
(University College London) Specially-adapted drones developed by a UCL-led international team have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions. The cutting-edge research at Manam volcano in Papua New Guinea is improving scientists’ understanding of how volcanoes contribute to the global carbon cycle, key to sustaining life on Earth.
