Mysterious Earthquakes Off Oregon

(GRANTS PASS, Ore.) – Scientists listening to underwater microphones have detected an unusual swarm of earthquakes off central Oregon, something that often happens before a volcanic eruption – except there are no volcanoes in the area.

Scientists don’t know exactly what the earthquakes mean, but they could be the result of molten rock rumbling away from the recognized earthquake faults off Oregon, said Robert Dziak, a geophysicist for the National Oceanic and Atmospheric Administration and Oregon State University.

There have been more than 600 quakes over the past 10 days in a basin 150 miles southwest of Newport. The biggest was magnitude 5.4, and two others were more than magnitude 5.0, OSU reported.

Commercial salmon fishing banned off western US

April 14, 2008April 12, 2008 by Infinite

Seattle – US regulators on Thursday ordered a ban on all commercial salmon fishing off California, Oregon and Washington in an emergency effort to help the decimated salmon population to recover. Under the terms of the ban only limited recreational salmon fishing will be allowed on holiday weekends off the Oregon coast.

According to official figures the salmon stock is at a historic low point as fewer and fewer fall chinook, or king salmon, have been returning to the Sacramento and Klamath rivers, over the last three years. The dismally low numbers have not been seen since 1954 and 1964, state officials say.

Fishermen and scientists blame three main factors for the shortfall. Mismanagement of the rivers, whose waters are often dammed and diverted to irrigate fields; overfishing, and the absence of up normal ocean upwelling – which usually stirs up tons of the ocean’s offshore nutrients which are the essential food needed by young salmon to survive.

Scientists take drugs to boost brain power: study

and you also become addicted to it. – The Infinite Unknown)

Twenty percent of scientists admit to using performance-enhancing prescription drugs for non-medical reasons, according to a survey released Wednesday by Nature, Britain’s top science journal.

The overwhelming majority of these med-taking brainiacs said they indulged in order to “improve concentration,” and 60 percent said they did so on a daily or weekly basis.

The 1,427 respondents — most of them in the United States — completed an informal, online survey posted on the “Nature Network” Web forum, a discussion site for scientists operated by the Nature Publishing Group.

More than a third said that they would feel pressure to give their children such drugs if they knew other kids at school were also taking them.

“These are academics working in scientific institutions,” Ruth Francis, who handles press relations for the group, told AFP.

The survey focused on three drugs widely available by prescription or via the Internet.

Ritalin, a trade name for methylphenidate, is a stimulant normally used to treat attention-deficit hyperactivity disorder, especially in children. Modafinil — marketed at Provigil — is prescribed to treat sleep disorders, but is also effective against general fatigue and jet lag.

Superfast internet may replace world wide web

The internet could soon be made obsolete by a new “grid” system which is 10,000 times faster than broadband connections.

Scientists in Switzerland have developed a lightning-fast replacement to the internet that would allow feature films and music catalogues to be downloaded within seconds.

GM Seeds Still Active in Soil 10 Years Later

January 13, 2009April 4, 2008 by Infinite

Scientists discovered seeds from certain genetically modified crops can endure soil for at least 10 years in some cases.

A field planted with experimental oilseed rape a decade ago found transgenic specimens were still growing there despite intensive efforts over the years to remove the seeds, according to researchers in Sweden.

This is the first time a genetically modified crop has endured so long and critics say it shows that genetically modified organisms cannot be contained once released.

Tina D’Hertefeldt and a team of researchers from Lund University searched a small field that hosted the GM trial 10 years ago looking for “volunteers” – plants that have sprung up spontaneously from seed in the soil.

“We were surprised, very surprised,” said D’Hertefeldt. “We knew that volunteers had been detected earlier, but we thought they’d all have gone by now.”

Lab Freaks Gone Wild?

Scientists plan to make “cybrids” by putting human DNA into cow eggs.The British government gave the go-ahead this week for two separate groups to experiment with the process. Scientists will “inject human DNA into empty eggs from cows, to create embryos known as cytoplasmic hybrids that are 99.9 per cent human in genetic terms,” according to The Times of London.
