Many U.S. presidents during their terms were seriously interested in UFOs and extraterrestrial intelligence issues, and some of them even had a chance to make contact with aliens. We turn to the recently declassified archives of ufology. Let’s start with 1948, when President Harry S. Truman summoned his Assistant Robert Landry to the Oval Office.
Truman gave him the order to make reports every three months on the flying saucers observed over the country. Once, Truman asked to investigate the case of the appearance of mysterious object over Washington that he observed through his window. (more…)
*Widespread urban development alters weather patterns*
New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.
The international study, led by the National Center for Atmospheric Research (NCAR), could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas. (more…)
Global warming over the next 40 years will cut through Arctic transportation networks like a double-edged sword, limiting access in certain areas and vastly increasing it in others, a new UCLA study predicts.
“As sea ice continues to melt, accessibility by sea will increase, but the viability of an important network of roads that depend on freezing temperatures is threatened by a warming climate,” said Scott Stephenson, a UCLA graduate student in geography and the study’s lead author. (more…)
*Climate models predict stable wind energy patterns over the United States*
Rising global temperatures will not significantly affect wind energy production in the United States concludes a new study published this week in the Proceedings of the National Academy of Sciences Early Edition.
But warmer temperatures could make wind energy somewhat more plentiful say two Indiana University (IU) Bloomington scientists funded by the National Science Foundation (NSF). (more…)
*Discovery of self-corrective healing process for polymer detailed this week in the journal Nature*
Imagine you’re driving your own new car–or a rental car–and you need to park in a commercial garage. Maybe you’re going to work, visiting a mall or attending an event at a sports stadium, and you’re in a rush. Limited and small available spots and concrete pillars make parking a challenge. And it happens that day: you slightly misjudge a corner and you can hear the squeal as you scratch the side of your car–small scratches, but large anticipated repair costs.
Now imagine that that you can repair these unsightly scratches yourself–quickly, easily and inexpensively–or that you can go through a car wash that can detect these and other more minor scratches and fix them as the car goes through the washing garage. Fantasy. Not exactly. Not anymore. Not according to a new discovery detailed in the April 21 issue of the journal Nature, and depicted in a short video interview and simulation. (more…)
*Study shows daily malleability on a long-term question*
Social scientists are struggling with a perplexing earth-science question: as the power of evidence showing manmade global warming is rising, why do opinion polls suggest public belief in the findings is wavering? Part of the answer may be that some people are too easily swayed by the easiest, most irrational piece of evidence at hand: their own estimation of the day’s temperature.
In three separate studies, researchers affiliated with Columbia University’s Center for Research on Environmental Decisions (CRED) surveyed about 1,200 people in the United States and Australia, and found that those who thought the current day was warmer than usual were more likely to believe in and feel concern about global warming than those who thought the day was unusually cold. A new paper describing the studies appears in the current issue of the journal Psychological Science. (more…)
ANN ARBOR, Mich.— Since 2003, the antiwar movement in the United States has had much to protest with Americans fighting in Iraq, Afghanistan and now Libya, but the movement—which has dropped off sharply the past two years—may be more anti-Republican than antiwar, says a University of Michigan researcher.
A new study by U-M’s Michael Heaney and colleague Fabio Rojas of Indiana University shows that the antiwar movement in the United States demobilized as Democrats, who had been motivated to participate by anti-Republican sentiments, withdrew from antiwar protests when the Democratic Party achieved electoral success, first with Congress in 2006 and then with the presidency in 2008.

It’s not often that plants are described as diabolical, but spotted knapweed has that rare distinction. A 2004 issue of Smithsonian magazine, for instance, dubbed it the “wicked weed of the West,” a “national menace” and a “weed of mass destruction.”
Such reports were overstated and incorrect, but the press wasn’t making this stuff up. It was summarizing research results published in leading academic journals.(more…)
