Two strains of bacteria team up, thrive on limited resources
In a discovery that further demonstrates just how unexpected and unusual nature can be, scientists have found two strains of bacteria whose symbiotic relationship is unlike anything seen before.
New estimate of living biomass: One third less life on planet Earth
Estimates of the total mass of all life on Earth should be reduced by about one third, based on the results of a study by a team of scientists at the University of Rhode Island's Graduate School of Oceanography ...
Scientists detect huge carbon 'burp' that helped end last ice age
(PhysOrg.com) -- Scientists have found the possible source of a huge carbon dioxide 'burp' that happened some 18,000 years ago and which helped to end the last ice age.
Global cooling as significant as global warming, research shows
A "cold snap" 116 million years ago triggered a similar marine ecosystem crisis to those witnessed in the past as a result of global warming, according to research published today in Nature Geoscience.
Massive volcanoes, meteorite impacts delivered one-two death punch to dinosaurs: study
(PhysOrg.com) -- A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs ...
Scientists discover new variability in iron supply to the oceans with climate implications
The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed – with implications for future climate prediction.
Ice ages only thanks to feedback
Ice ages and warm periods have alternated fairly regularly in the Earth's history: the Earth's climate cools roughly every 100,000 years, with vast areas of North America, Europe and Asia being buried under ...
Research explains mystery of ocean sediment
(PhysOrg.com) -- New research by an international team of researchers has revealed the previously unidentified role that fish play in the production of sediments in the world's oceans.
First detailed report defines limits of methane-exhaling microbial life in an undersea volcano
By some estimates, a third of the Earth's organisms by mass live in our planet's rocks and sediments, yet their lives and ecology are almost a complete mystery. This week, microbiologist James Holden at the ...
Ocean iron affects biological productivity: study
(PhysOrg.com) -- A team of researchers has just published a new paper, lead authored by Boston University Professor of Earth Sciences Richard W. Murray, that provides compelling evidence from marine sediment ...
Arabic records allow past climate to be reconstructed
Corals, trees and marine sediments, among others, are direct evidence of the climate of the past, but they are not the only indicators. A team led by Spanish scientists has interpreted records written in Iraq ...
Living power cables discovered
A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away.
Antarctic team digs deep to predict climate future
Nancy Bertler and her team took a freezer to the coldest place on Earth, endured weeks of primitive living and risked spending the winter in Antarctic darkness, to go get ice—ice that records our climate's ...
New interpretation of Antarctic ice cores
Climate researchers at the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association (AWI) expand a prevalent theory regarding the development of ice ages. In the current issue of the journal Nature three ...
