Powerful new tool to track carbon dioxide by source
Scientists from NOAA's Earth System Research Laboratory released today a powerful new tool to monitor changes in atmospheric carbon dioxide and other greenhouse gases by region and source around the world. Called CarbonTracker, the online system will distinguish between changes in the natural carbon cycle and those occurring in fossil fuel... view more... (2007-03-22)
US fires release large amounts of carbon dioxide
Large-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year. view more (2007-11-01)
New dinosaur species from Montana
A husband and wife team of American paleontologists has discovered a new species of dinosaur that lived 112 million years ago during the early Cretaceous of central Montana. view more (2009-11-02)
Oldest animal fossils may have been bacteria
The oldest-known animal eggs and embryos, whose first pictures made the cover of Nature in 1998, were so small they looked like bugs - which, it now appears, they may have been. view more (2006-12-21)
What we can learn from the biggest extinction in the history of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences. view more (2007-08-10)
Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect. view more (2006-09-12)
Fossilized cashew nuts reveal Europe was important route between Africa and South America
Cashew nut fossils have been identified in 47-million year old lake sediment in Germany, revealing that the cashew genus Anacardium was once distributed in Europe, remote from its modern "native" distribution in Central and South America. view more (2007-10-18)
Ecologists follow the footprints of Scott
Important new data from the plant fossil record that are helping ecologists to improve the accuracy of climate change models will be announced at the British Ecological Society symposium at the Society for Experimental Biology's annual meeting, being held at the University of Southampton between 1 and 4 April 2003. Dr Colin Osborne and his... view more... (2003-03-26)
Scientists Use MicroRNAs to Track Evolutionary History for First Time
The large group of segmented worms known as annelids, which includes earthworms, leeches and bristle worms, evolved millions of years ago and can be found in every corner of the world. view more (2009-09-10)
Major progress in technology needed for 25 percent renewable energy use to be affordable
Dramatic progress in renewable energy technology is needed if the United States desires to produce 25 percent of its electricity and motor vehicle fuel from renewable sources by 2025 without significantly increasing consumer costs. view more (2008-06-25)
Link between tropical warming and greenhouse gases stronger than ever, say scientists
New evidence from climate records of the past provides some of the strongest indications yet of a direct link between tropical warmth and higher greenhouse gas levels, say scientists at the University of California, Santa Barbara. view more (2005-10-14)
Chicken-hearted tyrants
Two titans fighting a bloody battle - that often turns fatal for both of them. This is how big predatory dinosaurs like Tyrannosaurus are often depicted while hunting down their supposed prey: even larger herbivorous dinosaurs. view more (2009-08-07)
Nuclear cannibals
Nuclear energy production must increase by more than 10 percent each year from 2010 to 2050 to meet all future energy demands and replace fossil fuels, but this is an unsustainable prospect. view more (2008-03-05)
Living Fossils Hold Record of 'Supermassive' Kick
The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. view more (2009-07-10)
Embryos tell story of Earth's earliest animals
Much of what scientists learn about the evolution of Earth's first animals will have to be gleaned from spherical embryos fossilized under very specific conditions. view more (2006-03-30)
Research discovers oldest bee, evolutionary link
Researchers at Oregon State University have discovered the oldest bee ever known, a 100 million year old specimen preserved in almost lifelike form in amber, and an important link to help explain the rapid expansion of flowering plants during that distant period. view more (2006-10-26)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Amateur Finds Prehistoric Lizard
When amateur fossil finder Van Turner discovered a small vertebra at a construction site near Dallas 16 years ago, he knew the creature was unlike anything in the fossil record. view more (2005-11-17)
Biofuels: An advisable strategy?
Biofuels have been an increasingly hot topic on the discussion table in the last few years. In 2003 the European Union introduced a Directive suggesting that Member states should increase the share of biofuels in the energy used for transport to 2% by 2005 and 5.75% by 2010. view more (2007-03-08)
Ancient predator had strongest bite of any fish, rivaling bite of large alligators and T. rex
t could bite a shark in two. It might have been the first "king of the beasts." And it could teach scientists a lot about humans, because it is in the sister group of all jawed vertebrates. view more (2006-11-29)
