Danube set for green overhaul
- The Danube -- and its role as a trading route -- has been severely
affected by repeated pollution and bomb damage to bridges crossing the river
during the Kosovo conflict. Delegates from 16 eastern European countries are
in Bucharest mapping out a plan to clean up and revitalise the Danube and
Carpathian mountain area.
Canada ice core to yield clues on global warming
- A team of Canadian scientists will launch an international expedition
next week to extract a long needle of ice from a giant haystack of a mountain
that will reveal the secrets of 10,000 years of climate change.
First Dinosaur Found With Its Body Covering Intact; Displays Primitive Feathers
From Head To Toe
- A team of Chinese and American scientists announced today in Nature
the discovery of a remarkably preserved, 130-million-year-old fossil dinosaur
covered from head to tail with downy fluff and primitive feathers. It is the
first dinosaur found with its entire body covering intact, providing the best
evidence yet that animals developed feathers for warmth before they could fly.
Air Pollution Control Efforts Will Add To Global Warming If Carbon Monoxide Is
Not Curbed Along With Nitrogen Oxides
- Climate researchers are warning that efforts to reduce air pollution
could, if not well designed, make global warming worse. Limiting emissions of
manmade nitrogen oxides, a strategy to control ozone in the lower atmosphere,
would result in increased methane abundance and lead to additional greenhouse
Scientists say Great Barrier Reef choking to death
- Australia's Great Barrier Reef risks choking to death on
fertilizer-soaked silt thanks to the clearance of wetlands and rainforests
along the neighboring Queensland coast, scientists said on Wednesday.
Ancient Climate Excursion Linked To A Rare Anomaly In Earth's Orbit
- About 23 million years ago, a huge ice sheet spread over Antarctica,
temporarily reversing a general trend of global warming and decreasing ice volume.
Now a team of researchers has discovered that this climatic blip at the boundary
between the Oligocene and Miocene epochs corresponded with a rare combination
of events in the pattern of Earth's orbit around the Sun.
Small Streams Contribute Far More Than Previously Thought To Cleaning Waterways
- Small streams remove more nutrients such as nitrogen from water than
do their larger counterparts, according to researchers who have applied sampling
methods developed in a National Science Foundation (NSF) Arctic area ecological
study to waterways across the nation.
Measurements Of An Exposed Earthquake Fault Helps Scientists Understand Subsurface
Faults' Behavior, Improve Hazard Forecasts
- Geological scientists know something of the causes of earthquakes,
and they know where many faults are located. However, they know much less about
the rocks within the fault zone that control earthquake properties. But seismic
studies of an exposed fault are now providing new information - and at least
Geologists' Discoveries Of How Sandstone Traps Riches Will Help Oil, Gas Explorers
- Jason Reed, a doctoral student in geological sciences at Virginia
Tech, has determined that impervious cementing minerals deposited millions of
years ago surround porous compartments in thick sandstone now more than 1,000
Volcano erupts on ocean floor off Oregon coast
- A volcano has been erupting on the ocean floor off the southern
Oregon coast since Tuesday night, but it poses no threat to ships or coastal
communities, scientists say.
Oily Fossils Provide Clues To The Evolution Of Flowers
- "An abominable mystery" is how nineteenth-century naturalist
Charles Darwin referred to the origin of flowering plants, and the puzzle
remains as controversial today as ever. Now a team of Stanford geochemists
has entered the debate with evidence that flowers may have evolved 250
million years ago - long before the first pollen grain appeared in the fossil record.
