Researchers Contribute Climate Model to Study That Finds Some Winds Decreasing

Declining wind speeds in parts of the United States could impact more than the wind power industry, say Iowa State University climate researchers. Three Iowa State researchers contributed their expertise in modeling North America’s climate to a study to be published in the Journal of Geophysical Research – Atmospheres. The study – led by Sara C. Pryor, a professor of atmospheric science at Indiana University Bloomington – found that wind speeds across the country have decreased by an average of .

Biosecurity on Farms

There are times when perniciously false premises are treated as the criteria by which truth is determined. We lose the argument before it’s begun. And where does that leave us in our efforts to control mortal dangers of our own making? An article of faith among veterinarians and epidemiologists is that large industrial farms are both biosecure and biocontained: livestock pathogens such as highly pathogenic influenza can’t check in, and if they do, they can’t check out.

John Maynard Keynes

If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has. -JMK This recession that we have been suffering through since essentially late 2007 is not something new; our economic history contains numerous instances of negative-growth economies, some obviously worse than others. However, in many ways, our current situation has perhaps brought to light the name John Maynard Keynes; a name that most likely wasn’t familiar to most people before this recent downturn and even in the midst of our recession, who he actually was and how his writings have influenced our economy may not be well known.

First images of new worlds

Earth seems to have its first fuzzy photos of alien planets outside our solar system, images captured by two teams of astronomers. The pictures show four likely planets that appear as specks of white, nearly indecipherable except to the most eagle-eyed experts. All are trillions of miles away  three of them orbiting the same star, and the fourth circling a different star. None of the four giant gaseous planets are remotely habitable or remotely like Earth.
