Oil spill and microbes

Oil spill and microbes
In the results of a newly released study, researchers explain how they used DNA to identify microbes present in the Gulf of Mexico following the Deepwater Horizon oil spill--and the particular microbes responsible for consuming natural gas immediately after the spill. Water temperature played a key role in the way bacteria reacted to the spill, the scientists found.

Extra-Cold Winters in Northeastern North America
If you're sitting on a bench in New York City's Central Park in winter, you're probably freezing. After all, the average temperature in January is 32 degrees Fahrenheit. But if you were just across the pond in Porto, Portugal, which shares New York's latitude, you'd be much warmer--the average temperature is a balmy 48 degrees Fahrenheit. Throughout northern Europe, average winter temperatures are at least 10 degrees Fahrenheit warmer........Go to the Geography-blog (Added on 3/31/2011 11:04:55 PM)


EarthScope Seismic Sensors Head East of the Mississippi

EarthScope Seismic Sensors Head East of the Mississippi
Most seismic activity--and earthquakes--have been in the U.S. West. But the East is not out of the woods in terms of risk, geologists say. After a six-year march eastward from the U.S. West Coast, the EarthScope Transportable Array seismic network has reached a major milestone: installation of the first Transportable Array station east of the Mississippi River. Station 345A, located on a private farm about 15 miles northwest of Columbia,........Go to the Geography-blog (Added on 3/31/2011 10:57:34 PM)


Communicating uncertain climate risks

Communicating uncertain climate risks
Despite much research that demonstrates potential dangers from climate change, public concern has not been increasing. One theory is that this is because the public is not intimately familiar with the nature of the climate uncertainties being discussed. "A major challenge facing climate researchers is explaining to non-specialists the risks and uncertainties surrounding potential" climate change, says a new Perspectives piece published........Go to the Geography-blog (Added on 3/30/2011 7:13:27 AM)


First practical 'artificial leaf'

First practical 'artificial leaf'
esearchers today claimed one of the milestones in the drive for sustainable energy � development of the first practical artificial leaf. Speaking here at the 241st National Meeting of the American Chemical Society, they described an advanced solar cell the size of a poker card that mimics the process, called photosynthesis, that green plants use to convert sunlight and water into energy.

Algae and bacteria hogged oxygen after ancient mass extinction

Algae and bacteria hogged oxygen after ancient mass extinction
A mass extinction is hard enough for Earth's biosphere to handle, but when you chase it with prolonged oxygen deprivation, the biota ends up with a hangover that can last millions of years. Such was the situation with the greatest mass extinction in Earth's history 250 million years ago, when 90 percent of all marine animal species were wiped out, along with a huge proportion of plant, animal and insect species on land.

Direct experience of extreme weather events increases concern about climate change and willingness to engage in energy-saving behaviour, as per a new research paper reported in the first edition of the journal Nature Climate Change this week.

Can Biochar Help Suppress Greenhouse Gases?

Can Biochar Help Suppress Greenhouse Gases?
Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are responsible for an increase in nitrous oxide emissions from grazing animals' excrement. Biochar is potentially a mitigation option for reducing the world's elevated carbon dioxide emissions, since the embodied carbon can be sequestered in the soil. Biochar also has the potential to........Go to the Geography-blog (Added on 3/18/2011 10:06:28 PM)


Enhancing the Magnetism

Enhancing the Magnetism
"The nation that controls magnetism will control the universe," famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there's little doubt the nation that leads the development of advanced magnetoelectronic or "spintronic" devices is going to have a serious leg-up on its Information Age competition.

Golf courses that reuse water
Irrigation is one of the most controversial aspects in the sustainable management of golf courses. Scientists from the Canary Islands have spent 25 years analysing the practices relating to reclaimed water at one of the oldest golf courses in Spain. The results show that plants on the course receive 83% more water than they need.

Earth's Sixth Mass Extinction
With the steep decline in populations of a number of animal species, researchers have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years.

Despite the fears of some, a newly released study suggests that use of the internet in general does not make people more likely to believe political rumors.

Observing Arctic ice-edge plankton blooms
"Ice-edge phytoplankton blooms in the Arctic Ocean provide food for planktonic animals called zooplankton, which are in turn exploited by animals higher up the food chain such as fish," explained Dr Andrew Yool, one of the team of NOC researchers.

Small Cars in the Big City

Small Cars in the Big City
In large cities, space is limited and only the elite can afford the vast garage fees and high insurance rates. This is one of the main reasons why small cars have become such a popular choice for those who live in a big city. With many compact options, people living in the city are more apt to buy a smaller car, one that will just meet their daily needs. When choosing these small cars, it is important to think of practicality. Will it allow........Go to the Auto-blog (Added on 2/27/2011 8:11:11 PM)


Oldest Fossils of Large Seaweeds

Oldest Fossils of Large Seaweeds
Almost 600 million years ago, before the rapid evolution of life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche near what is now Lantian, a small village in south China. Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free and unbreathable waters.

The microscopic phytoplankton Aureococcus anophagefferens, which causes devastating brown tides, appears to be tiny but it's proven to be a fierce competitor.
