Complex Systems Last Updated on 2013-10-24 15:13:11 As Science has begun to ask where the enduring features of nature come from and how they work, the answer seems to be “complex systems”.  Every kind of thing and event seems to require them.  As the science has advanced, and as the modern problems of economies and environmental conflicts emerge, a new kind of science is emerging that requires being very openly exploratory, using all the tools and combining all the related perspectives of others, to develop complex knowledge systems matching the variety of the complex system problems they respond to. Systems are storms or “like storms” in many respects, complex distributed phenomena that may be either unexpectedly eventful or highly predictable.  There’s still a rather wide range of opinion within science as to what complex systems are, even whether they are made of information or...

Toxicity testing- new dimensions Last Updated on 2013-09-13 23:25:02 This article, written by Charles W. Schmidt[1], appeared first in Environmental Health Perspectives—the peer-reviewed, open access journal of the National Institute of Environmental Health Sciences. The article is a verbatim version of the original and is not available for edits or additions by Encyclopedia of Earth editors or authors. Companion articles on the same topic that are editable may exist within the Encyclopedia of Earth. On the ground floor of the National Institutes of Health Chemical Genomics Center (NCGC) in Rockville, Maryland, a $10-million automated laboratory spends all day and night screening chemicals at speeds no team of human researchers could ever match. In a week, depending on the nature of the assay, it can yield up to 2.2 million molecular data points derived from thousands of chemicals tested at 15 concentrations each. Is this the new face...

New frog species in New York City Last Updated on 2012-03-15 00:00:00 Biologists regularly discover new species in remote rainforests. Finding one in ponds and marshes--sometimes within view of the Statue of Liberty--is a big surprise. Hiding in Plain Sight, New Frog Species Found in New York City Leopard frog's habitat covers very small region, likely went extinct in larger territory In the wilds of New York City--or as wild as you can get that close to skyscrapers--scientists have found a new leopard frog species. For years, biologists mistook it for a more widespread variety of leopard frog. While biologists regularly discover new species in remote rainforests, finding this one in ponds and marshes--sometimes within view of the Statue of Liberty--is a big surprise, said scientists from the University of California, Los Angeles; Rutgers University; the University of California, Davis and the University of Alabama.

Comments: NOAA draft environmental impact statement on Arctic oil and gas exploration Last Updated on 2011-12-28 00:00:00 NOAA seeks comment on draft environmental impact statement on Arctic oil and gas exploration NOAA is seeking public comment on a draft environmental impact statement describing how offshore oil and gas activities in the U.S. Beaufort and Chukchi seas could affect marine mammals and the Alaska Native communities that depend on them for subsistence. The document also examines measures to lessen potential effects. The draft EIS, released today, looks at measures NOAA could adopt over the next five years as it issues incidental take authorizations under the Marine Mammal Protection Act in the area. The EIS will also contribute to decisions made by the Department of the Interior’s Bureau of Ocean Energy Management on issuing permits for seismic surveys. The Marine Mammal Protection Act directs the Secretary of Commerce to allow the incidental and unintentional take of... More »
