Scientists have discovered that air flows in one direction as it loops through the lungs of alligators, just as it does in birds. The results, published in this week's issue of the journal Science, suggest that this breathing method may have helped dinosaurs' ancestors dominate Earth after the planet's worst mass extinction 251 million years ago. Before and until about 20 million years after the extinction--called "the Great Dying" or the Permian-Triassic extinction--mammal-like reptiles...

The collision between the Siberian Plate and North China Plate was a significant geological event in earth history, which led to the final closure of the Paleoasian Ocean and the formation of the Eurasian continent. Despite numerous research efforts in recent decades, the precise time of this event has remained a puzzle until now. New evidence in helping settle this issue is provided by Prof. Deng Shenghui and his colleagues in their paper newly published in Science in China (2009, vol.52)....

The largest known mass extinction in Earth's history, about 252 million years ago at the end of the Permian Period, may have been caused by global warming. A new fossil species suggests that some land animals may have survived the end-Permian extinction by living in cooler climates in Antarctica. Jörg Fröbisch and Kenneth D. Angielczyk of The Field Museum together with Christian A. Sidor from the University of Washington have identified a distant relative of mammals, Kombuisia...

Environmental selectivity during three of the "ËœBig Five' mass extinction events focus of two paleontologists' latest research. Arnie Miller, University of Cincinnati professor of paleontology in the McMicken College of Arts & Sciences, and co-author Michael Foote of the University of Chicago publish their research in the Nov. 20 issue of Science with their paper, "Epicontinental Seas Versus Open-Ocean Settings: The Kinetics of Mass Extinction and Origination." For many years,...

Tiny organisms that covered the planet more than 250 million years ago appear to be a species of ancient fungus that thrived in dead wood, according to new research published October 1 in the journal Geology. The researchers behind the study, from Imperial College London and other universities in the UK, USA and The Netherlands, believe that the organisms were able to thrive during this period because the world's forests had been wiped out. This would explain how the organisms, which are...

Did volatile halogenated gases from giant salt lakes at the end of the Permian Age lead to a mass extinction of species? The largest mass extinction in the history of the earth could have been triggered off by giant salt lakes, whose emissions of halogenated gases changed the atmospheric composition so dramatically that vegetation was irretrievably damaged. At least that is what an international team of scientists have reported in the most recent edition of the "Proceedings of the Russian...

South Africa's Karoo Basin Shows No Indication of "Boundary Event Rock Bed" New scientific findings by geologist Robert Gastaldo of Colby College in Waterville, Maine, and colleagues call into question popular theories about the largest mass extinction in Earth's history. A paper reporting the results by Gastaldo, South African scientist Johann Neveling, and two 2008 Colby undergraduate students, C. Kittinger "Kit" Clark and Sophie Newbury, appears in the March 2009 issue of GEOLOGY. Tens of...

Evidence suggests that 'sick Earth' extinctions more likely In geology as in cancer research, the silver bullet theory always gets the headlines and nearly always turns out to be wrong. For geologists who study mass extinctions, the silver bullet is a giant asteroid plunging to earth. But an asteroid is the prime suspect only in the most recent of five mass extinctions, said USC earth scientist David Bottjer. The cataclysm 65 million years ago wiped out the dinosaurs. "The other four have not...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
