The ancient North American city of Cahokia had as its focal point a feature now known as Monks Mound, a giant earthwork surrounded on its north, south, east and west by large rectangular open areas.
Scientists have long thought the unique geography of the Philippines — coupled with seesawing ocean levels — could have created a “species pump” that triggered massive diversification by isolating, then reconnecting, groups of species again and again on islands.
Higher water temperatures induce specific chemical tags at targeted locations on the DNA of embryonic zebrafish.
Recently, the research by Dr Liao Wenling (State Key Joint Laboratory of Environmental Simulation and Pollution Control, Department of Environmental Science, Peking University) was published in SCIENCE CHINA Earth Science.
Researchers discover a new fossil that is closely related to other animals that made the transition to land, but with features more suited for swimming and life in the water.
Scientists have developed an artificial protein that could offer new insights into chemical evolution on early Earth. All cells need energy to survive, but because the kinds of chemicals available during the planet’s early days were so limited compared to today’s vast scope of chemical diversity, multicellular organisms had a lot less energy to build the complex organic structures that make up the world we know today.
The Vienna Statement on Science Diplomacy has been endorsed by more than one hundred eminent personalities from the academic and policymaking community.
Water resources will fluctuate increasingly and become more and more difficult to predict in snow-dominated regions across the Northern Hemisphere by later this century, according to a comprehensive new climate change study led by the National Center for Atmospheric Research (NCAR) and co-authored by a Cornell University climate scientist.
Three new species of black-bellied salamander have been discovered by a research team led by R. Alexander Pyron, the Robert F. Griggs Associate Professor of Biology at the George Washington University. The new salamanders, which are found in the southern Appalachian Mountains of the eastern United States, stem from black-bellied populations that were long considered to be a single species.
Scientists investigating the growth of arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming planet.

The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state’s climate-change solution arsenal may be in jeopardy, as new research from the University of California, Irvine reports that trees in California’s mountain ranges and open spaces are dying from wildfires and other pressures – and fewer new trees are filling the void.
More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
