A Hazy View Of Early Earth Moffett Field CA (SPX) Oct 19, 2009 
Haze in the early Earth atmosphere could have played a crucial role in the origin of life. By forming a protective shield, the haze would have safeguarded organic substances from harmful ultraviolet (UV) radiation. "Knowing more about the atmospheric conditions right before life began to develop could give researchers clues to how exactly life developed," says H. Langley DeWitt of the ... read moreScientists find flying reptile an odd duck 
Portsmouth, England (UPI) Oct 14, 2009 Fossils of a flying reptile found in China reveal a strangely disjointed creature, British paleontologists say. "It's as if someone said, 'Let's nail these two together and make a sort of chimera, that'll really confuse everybody,'" said Dave Unwin of the University of Leicester in England. This version of pterodactyl appears so strange it conjures up the image of an old second-r ... more

Huge dinosaur find in China may include new species: state media
Beijing (AFP) Oct 14, 2009Paleontologists in east China may have discovered the remains of a new species of dinosaur at what is said to be the world's largest group of fossilised dinosaur bones, state media said Wednesday. Scientists in Zhucheng city, Shandong province, have for months been exploring a gully over 500 metres (1,650 feet) long and 26 metres deep that is strewn with thousands of dinosaur bones, the Jilu ... more Date of Earth's Quaternary age revised 
London (UPI) Sep 23, 2009 The International Commission on Stratigraphy says it has revised the date of the start of Earth's prehistoric Quaternary Period by 800,000 years. The London-headquartered commission -- the authority for geological science -- decided to end decades of controversy by formally declaring when the Quaternary Period started. The Quaternary age covers both the ice age and moment early man ... more Key Ingredient In Cooking Up Prebiotic Molecules 
Potsdam, Germany (SPX) Sep 18, 2009German scientists investigating the complex chemical mixture thought to be present in the early Earth's oceans have found that amino acids can be 'cooked' into many other important chemical building blocks of life when embedded in salt crusts. Results of the laboratory experiments will be presented by Stefan Fox at the European Planetary Science Congress in Potsdam, Germany. Approximately ... more 'Tiny' new T-Rex ancestor unearthed in China 
Chicago (AFP) Sept 17, 2009A relatively tiny new ancestor of the Tyrannosaurus rex has been unearthed in China, researchers said Thursday. The three-meter-long (10-foot) dinosaur dubbed the Raptorex only weighed about 60 kilograms (150 pounds) and was nearly 100 times smaller than the king of the dinosaurs. But it was nearly identical in structure -- even down to the scrawny arms -- and had all of the traits which ... more |

Giant marine worms lived 475 million years ago: scientists
Cabaneros National Park, Spain (AFP) Aug 3, 2009Spanish researchers said Monday they have discovered evidence of a type of giant worm that lived 475 million years ago and was up to one metre (three feet) in length. The fossilised tracks of the marine worms were found in the Cabaneros National Park in central Spain in an area that was a seabed during the Lower Ordovician period, the Spanish National Research Council (CSIC) said. ... more Extraterrestrial Platinum Was Stirred Into The Earth 
Canberra, Australia (SPX) Jul 30, 2009A research program aimed at using platinum as an exploration guide for nickel has for the first time been able to put a time scale on the planet's large-scale convection processes. The research is reported in a Nature paper titled "Progressive mixing of meteoritic veneer into the early Earth's deep mantle". Report author CSIRO Minerals Down Under Flagship researcher Dr Stephen Barnes said ... more Mystery mechanism drove global warming 55 million years ago 
Paris (AFP) July 13, 2009A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday. Previous research into this period, called the Palaeocene-Eocene Thermal Maximum, or PETM, estimates the planet's surface temperature blasted upwards by between five and nine degrees Celsius (nine and 16.2 degrees Fahrenheit) in just ... more Rock Bands Spin An Oxygen Record 
Moffett Field CA (SPX) Jun 23, 2009The first half of Earth's history was devoid of oxygen, but it was far from lifeless. There is ongoing debate over who the main biological players were in this pre-oxygen world, but researchers are digging up clues in some of the oldest sedimentary rocks on the planet. Most scientists believe the amount of atmospheric oxygen was insignificant up until about 2.4 billion years ago when the ... more |
