From The Guardian:

Woolly mammoths and other giant ice-age mammals faced extinction 2,000 years before deadly speartips were invented.

Woolly mammoths and other large, lumbering beasts faced extinction long before early humans perfected their skills as spearmakers, scientists say.

The prehistoric giants began their precipitous decline nearly 2,000 years before our ancestors turned stone fragments into sophisticated spearpoints at the end of the last ice age.

Google Chrome OS: Why Should People Switch?

Google Chrome OS isn't scheduled to arrive for another year, but Google has a lot to do before then to make the project attractive to the average user. (Google Chrome OS screenshot)

From The Christian Science Monitor:

Google Chrome OS has buzz now, but a number of stars will have to align for many folks to migrate to it.

Will you be using Chrome OS a year from now?

At the Web-based operating system’s coming-out party at Google headquarters on Thursday, Google presented its vision of Chrome, and a huge amount of information on what the browser and operating system are based on, how they run, and the safeguards in place to ensure they run well. But missing in all of that, at least to this observer, was a clear exposition of how Google plans to get users onboard – in essence, the hook.

U.S. Exhausted Oil And Gas Supplies — Repeatedly -- A Commentary


From The Houston Chronicle:

What city contributed most to the making of the modern world? The Paris of the Enlightenment and then of Napoleon, pioneer of mass armies and nationalist statism? London, seat of parliamentary democracy and center of finance? Or perhaps Titusville, Pa.

Oil seeping from the ground there was collected for medicinal purposes — until Edwin Drake drilled and 150 years ago — Aug. 27, 1859 — found the basis of our world, 69 feet below the surface of Pennsylvania, which oil historian Daniel Yergin calls “the Saudi Arabia of 19th-century oil.”

For many years, most oil was used for lighting and lubrication, and the amounts extracted were modest. Then in 1901, a new well named for an East Texas hillock, Spindletop, began gushing more per day than all other U.S. wells combined.

Since then, America has exhausted its hydrocarbon supplies.

Repeatedly.

How 16 Ships Create As Much Pollution As All The Cars In The World

Waiting game: Tankers moored off Devon waiting for oil prices to rise even further

From The Daily Mail:

Last week it was revealed that 54 oil tankers are anchored off the coast of Britain, refusing to unload their fuel until prices have risen.

But that is not the only scandal in the shipping world. Today award-winning science writer Fred Pearce – environmental consultant to New Scientist and author of Confessions Of An Eco Sinner – reveals that the super-ships that keep the West in everything from Christmas gifts to computers pump out killer chemicals linked to thousands of deaths because of the filthy fuel they use.

Acid Oceans Leave Fish At More Risk From Predators

From The BBC:

Ocean acidification could cause fish to become "fatally attracted" to their predators, according to scientists.

A team studying the effects of acidification - caused by dissolved CO2 - on ocean reefs found that it leaves fish unable to "smell danger".

Young clownfish that were reared in the acidified water became attracted to rather than repelled by the chemical signals released by predatory fish.

The findings were published in the journal Ecology Letters.

From Times Online:

Understanding and predicting longevity are vital if we are to manage the implications of greater life expectancy.

There’s been a lot of news recently about dying — or, more exactly, about surviving. According to figures for 2006-08 just published by the Office for National Statistics, life expectancy at birth in the Royal Borough of Kensington and Chelsea, West London, has reached 84.3 years for males, 88.9 for females.

Bing: Google Gets Some Real Competition


From the Christian Science Monitor:

It’s hard to compete when your opponent’s name is so popular that it’s become a verb. Such is the plight of every search engine that dares to challenge Google.

Last year, four search engines made up more than 95 percent of all search traffic: Google, Yahoo, MSN, and Ask. Only Google increased its share of the pie that year, eating up 67 percent of all searches in January and 72 percent by 2009, according to the online traffic monitor Hitwise.

A Look At Global Warming Written In A Cooler And More Skeptical Time, Giving Us A Better Understanding Of Climate Science

Hackers targeted the University of East Anglia's Climatic Research Unit, pictured, and published sensitive emails on the internet. Photo from The Daily Mail.

From Fabius Maximus:

The hacked emails and papers from the UK’s Climate Research Unit reveal the underside of climate science (as the many bizarre conclusions do the same for the anti-AGW mob). Spinning data to conceal contrary evidence, avoiding freedom of information requests, purging the profession of skeptical voices. All familiar things to anyone familiar with the history of science. All evidence of the most important step needed, and that most strongly opposed by most climate scientists:

Raise the standards when applying science research to public policy questions. That means requiring full transparency of data and methods used in climate science research, and third party review of the data, analysis, and models.

From Science Daily:

Science Daily (Nov. 22, 2009) — Solar wind generated by the sun is probably driven by a process involving powerful magnetic fields, according to a new study led by UCL (University College London) researchers based on the latest observations from the Hinode satellite.

Scientists have long speculated on the source of solar winds. The Extreme Ultraviolet Imaging Spectrometer (EIS), on board the Japanese-UK-US Hinode satellite, is now generating unprecedented observations enabling scientists to provide a new perspective on the 50-year old question of how solar wind is driven. The collaborative study, published in this month's issue of Astrophysical Journal, suggests that a process called slipping reconnection may drive these winds.

From Live Science:

That tuna in your sushi might be an endangered species, a new study finds.

Some genetic detective work by scientists has shown that bluefin tuna, an endangered fish, regularly gets put on the plates of sushi eaters in New York and Colorado.

"When you eat sushi, you can unknowingly get a critically endangered species on your plate," said Jacob Lowenstein, a graduate student affiliated with the American Museum of Natural History in New York and Columbia University. "But with an increasingly popular technique, DNA barcoding, it is a simple process for researchers to see just what species are eaten at a sushi bar."
