How being human and prickly adds character (and probably error) to the scientific process — Juan Collar, Elena Aprile, and Rita Bernabei in the Dark Matter Discovery Race 0

Background Science recently did a brief lay review of the race to find evidence for the dark matter that comprises roughly 25 percent of the mass-energy density of the Universe. For perspective, keep in mind that dark energy allegedly accounts for 70 percent of the mass-energy density of the Universe.  The matter and energy we [...]

Climatic interconnectivity — Eurasian autumn snow coverage affects North American winters more than previously thought 0

Predicting short-term seasonal characteristics A correlation study found that: The extent of snow cover over Eurasia during autumn has been shown to be influential in shaping atmospheric circulation over the Northern Hemisphere the following winter via the Arctic Oscillation (AO), North Atlantic Oscillation (NAO), and the Pacific/North American (PNA) teleconnections. Regions of Eurasian snow cover [...]

The 10-year “Tagging of Pacific Predators” study concluded with important evidence for two life-rich zones in the Pacific Ocean — Notice that this study would not have been possible without grants from charitable foundations 0

An environmentally important study funded by charitable foundations Barbara Block and colleagues recently published an important paper in Nature: Tagging of Pacific Predators, a field programme of the Census of Marine Life, deployed 4,306 tags on 23 species in the North Pacific Ocean, resulting in a tracking data set of unprecedented scale and species diversity [...]

Landsat 5’s pictures of Arizona’s Wallow fire — Arizona’s most extensive ever 0

Color-coded to help fire-fighters know where to go Courtesy of NASA: The Wallow fire began May 29, 2011 in the Bear Wallow Wilderness area located in eastern Arizona. High winds and low humidity meant that by June 14, 2011 the Wallow Fire became Arizona’s largest wildfire to date with over 487,016 acres burned. The Landsat [...]

Warming temperatures in the Southern Rocky Mountains are affecting blooming periods and probably the pollinators dependent on them 0

Not the kind of thing that one would necessarily anticipate George Aldridge and colleagues reported that: As mid-summer temperatures have warmed, we found that a montane meadow ecosystem in the southern Rocky Mountains of the United States exhibits a trend toward a bimodal distribution of flower abundance, characterized by a mid-season reduction in total flower [...]

Dimness and a high proportion of light elements and gas as an indicator of galactic youth and/or a very long look back in Universe time 0

Becoming a galactic extrovert takes time Galaxy ESO 546-G34 was first observed some twenty years ago.  A recent analysis, using new techniques, by astrophysicist Lars Mattsson and colleagues indicates that: “Our analysis shows that while a large, mature galaxy like our own galaxy, the Milky Way, is composed of around 15-20 percent gas, this faint [...]

30 “critical zone observatories” around the world are attempting to track and model changes to the Earth’s life-supporting surface 0

Courtesy of the National Science Foundation and the European Commission The National Science Foundation and the European Commission have funded a program that supports thirty “critical zone observatories” around the world. The University of Sheffield explains: In some parts of the world, losses due to erosion are greatly outstripping the natural rate of soil formation [...]

Are armadillos spreading leprosy in the United States at low rates? 0

A unique strain of Mycobacterium leprae has been found in U.S. armadillos and patients Mycobacterium leprae causes leprosy. For those of us who live or lived in armadillo country, a study in the New England Journal of Medicine bears interesting news: Wild armadillos and many patients with leprosy in the southern United States are infected [...]

One has to wonder about Representative Anthony Weiner’s judgment 0

Ordinarily, American political sex scandals are boring, given the wide swath that sexuality cuts through our lives, but — In Anthony Weiner’s case, what was he thinking? In scattering sexually-oriented photographs of himself across cyberspace, didn’t it occur to him that someone might take offense and ultimately sabotage his career? Face to face sexual peccadillos [...]
