Some of the earliest humans to inhabit America came from Europe according to a new book.

Across Atlantic Ice puts forward a compelling case for people from northern Spain travelling to America by boat, following the edge of a sea ice shelf that connected Europe and America during the last Ice Age, 14,000 to 25,000 years ago.

Across Atlantic Ice is the result of more than a decade’s research by leading archaeologists Professor Bruce Bradley of the University of Exeter and Dr Dennis Stanford of the Smithsonian Institution. Through archaeological evidence, they turn the long-held theory of the origins of New World populations on its head.

For more than 400 years, it has been claimed that people first entered America from Asia, via a land bridge that spanned the Bering Sea. We now know that some people did arrive via this route nearly 15,000 years ago, probably by both land and sea. (more…)

*Outstanding educators using technology are recognized for their contribution and impact in teaching.*

REDMOND, Wash. — Aug. 1, 2011 — Microsoft Corp. today announced 11 educators from Alabama, Alaska, California, Florida, Michigan, Pennsylvania, South Carolina and Washington who have been selected as winners of the 2011 U.S. Innovative Education Forum (IEF). The IEF is an event recognizing innovative teachers and school leaders who creatively and effectively use technology in their curriculum to help improve the way kids learn while increasing student success. Out of the thousands that applied, 100 educators from 25 states were selected for a spot to compete on Microsoft’s corporate campus in Redmond. IEF participants also voted on their peers in the Educator’s Choice category and selected a winning project. The winning educators will represent the U.S. and advance to compete against educators from around the world at the Partners in Learning Global Forum, Nov. 6–11, 2011 in Washington, D.C. (more…)

Significant Natural Gas Resources Remain to Be Discovered in Cook Inlet, Alaska

By Guest PostJuly 1, 2011Economy, Environmentalaska, alaska division of oil and gas, brenda pierce, coalbed gas, cook inlet, cook inlet region, natural gas, oil and gas resources, petroleum potential, U.S. Geological Survey, usgs, usgs assessment

The Cook Inlet Region of Alaska contains an estimated mean of 19 trillion cubic feet of natural gas, about 600 million barrels of oil, and 46 million barrels of natural gas liquids, according to a new assessment by the U.S. Geological Survey (USGS). This estimate is of undiscovered, technically recoverable oil and gas resources, and includes both unconventional and conventional resources.

These gas estimates are significantly more than the last USGS assessment of southern Alaska in 1995, in which a mean of 2.14 trillion cubic feet of gas was estimated. This increase in the undiscovered resource is attributed to new geologic information and data. (more…)

Web Use Doesn’t Encourage Belief in Poltical Rumors, But E-mail Does

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

However, one form of internet communication – e-mail – does seem to have troubling consequences for the spread and belief of rumors.

“I think a lot of people will be surprised to learn that using the internet doesn’t necessarily promote belief in rumors. Many people seem to think that’s self-evident,” said R. Kelly Garrett, author of the study and assistant professor of communication at Ohio State University. (more…)

‘Thawing Permafrost Likely Will Accelerate Global Warming in Coming Decades’

Up to two-thirds of Earth’s permafrost likely will disappear by 2200 as a result of warming temperatures, unleashing vast quantities of carbon into the atmosphere, says a new study by the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences.

The carbon resides in permanently frozen ground that is beginning to thaw in high latitudes from warming temperatures, which will impact not only the climate but also international strategies to reduce fossil fuel emissions, said CU-Boulder’s Kevin Schaefer, lead study author. “If we want to hit a target carbon dioxide concentration, then we have to reduce fossil fuel emissions that much lower than previously thought to account for this additional carbon from the permafrost,” he said. “Otherwise we will end up with a warmer Earth than we want.” (more…)

Three Giant Spaceships to Attack Earth in 2012?

UFO encounters became especially frequent in the middle of the 20th century, when it became impossible to disregard incidents of UFO sightings anymore. Special services started establishing special departments for air defense troops, secret laboratories were organized to study the phenomenon. It is not ruled out, that secret services have already had chances to study fragments of alien spaceships or even aliens themselves.

It is about time science should say its word regarding the problem, and it did. SETI (Search for Extraterrestrial Intelligence), an independent non-commercial organization, released a sensational statement. (more…)

Deformed Beaks May Signal a Greater Environmental Problem

This Black-capped Chickadee, captured in Anchorage, Alaska, demonstrates an overgrown beak characteristic of avian keratin disorder. Beak deformities in this species were first observed in the late 1990s and biologists have since documented more than 2,100 affected individuals in Alaska. Image credit: U.S. Geological Survey

ANCHORAGE, Alaska – The highest rate of beak abnormalities ever recorded in wild bird populations is being seen in a number of species in the Northwest and Alaska, and scientists to this point have not been able to isolate the cause.

Black-capped Chickadees, Northwestern Crows, and other birds are being impacted by the problem, which affects their ability to feed and clean themselves and could signal a growing environmental health problem.

In birds affected by what scientists have termed “avian keratin disorder,” the keratin layer of the beak becomes overgrown, resulting in noticeably elongated and often crossed beaks, sometimes accompanied by abnormal skin, legs, feet, claws and feathers. Biologists with the U.S. Geological Survey’s Alaska Science Center published their findings in this month’s issue of The Auk, a Quarterly Journal of Ornithology.

“The prevalence of these strange deformities is more than ten times what is normally expected in a wild bird population,” said research biologist Colleen Handel with the USGS, “We have seen effects not only on the birds’ survival rates, but also on their ability to reproduce and raise young. We are particularly concerned because we have not yet been able to determine the cause, despite testing for the most likely culprits.” (more…)

USGS Oil and Gas Resource Estimates Updated for the National Petroleum Reserve in Alaska (NPRA)

The U.S. Geological Survey estimates 896 million barrels of conventional, undiscovered oil and 53 trillion cubic feet of conventional, undiscovered non-associated gas within NPRA and adjacent state waters. The estimated volume of undiscovered oil is significantly lower than in 2002, when the USGS estimated there was 10.6 billion barrels of oil. The new estimate, roughly 10% of the 2002 estimate, is due primarily to the incorporation of new data from recent exploration drilling revealing gas occurrence rather than oil in much of NPRA. (more…)
