United Kingdom’s Brown Argus butterfly appears to adapting to climate change at the genetic level — as a result of expanding into differently apportioned food habitat 0

The underlying genetic change appears to be founded upon pre-existing gene diversity and its concomitant habitat preferences Which is what one would have predicted. Citation James Buckley, Roger K. Butlin, and Jon R. Bridle, Evidence for evolutionary change associated with the recent range expansion of the British butterfly, Aricia agestis, in response to climate change, [...]

The more self-adulatory hot air you blow, the better you do in the corporate world? — Apparently so, says Columbia Business School 0

Sad news for women, who deserve better based on their actual performances Men’s “honest” overconfidence gets them promoted to leadership over similarly competent women: Reuben and his coresearchers . . . asked MBA students to complete a set of math problems on which both men and women perform about the same. One year later, the [...]

Well, duh — life experiences up to middle age make a difference in establishing psychological baselines for anxiety and depression in a (tiny ?) sample of identical twins 0

Perhaps trivial evidence for what common sense already thought it knew Even with near-identical genetics (insofar as we can eliminate pre-existing epigenetic variances), life experience matters in regard to establishing habitual outlooks: Our life experiences – the ups and downs, and everything in between – shape us, stay with us and influence our emotional set [...]

Contrary to previous thinking, the domestication of dogs likely first occurred in China, south of the Yangtze River 0

When you leave out some important Asian genetic material, you get the wrong answer — said this research team Makes sense to me: Global mitochondrial DNA (mtDNA) data indicates that the dog originates from domestication of wolf in Asia South of Yangtze River (ASY), with minor genetic contributions from dog–wolf hybridisation elsewhere. Archaeological data and [...]

A Princeton University press release sums recent research that points to a combination of volcanic activity and multiple meteor strikes as being responsible for the Cretaceous-Tertiary (K-T) boundary extinction — with India’s Deccan Traps arguably being by the most significant contributors 0

A newer twist to an existing controversy Morgan Kelly, writing for Princeton’s Office of Communications, recently published an overview of important aspects of recent Cretaceous-Tertiary (K-T) extinction research. His summary makes gives readers a sense of what scientists in this arena argue about. At issue is the cause of the extinction that killed off the [...]

Curious as to why evolution has conserved genes for bacterial hydrogen sulfide production, researchers discovered that H2S reduces susceptibility to oxidative stress and, therefore, to antibiotics 0

The benefits of wondering why A research team considered the following, on its way to making an important discovery about the relationship between bacterial hydrogen sulfide production and reduced susceptibility to antibiotics: Hydrogen sulfide has (at least) five overlapping functions in mammals: anti-inflammatory action in the gut, cardiac protection, cellular signaling, neurotransmission, and vasodilation. The [...]

A computer model, generated from aerial mapping of actual conditions over time, shows that agricultural over-pumping of the High Plains (Ogallala) Aquifer will soon deprive native fish of the water that they have depended on since the last Ice Age 0

As the most recent Ice Age fades into the geologic past A research team has found that groundwater pumping — mainly for agricultural purposes (corn, wheat, and alfalfa) — in the Western Great Plains is having a negative effect on native fish. However, it is unlikely that anything can realistically be done to improve the [...]

Walking through doorways apparently makes it easier to forget what we intended to do — illustrating the impact of the doorway as an event horizon 1

I imagine many of us have noticed that our memory cataloging system appears to be modular It’s hard to remember something, when we forget which mind-drawer we put it in. Three recent psychology experiments support this idea. Susan Guibert’s press release explained what three Notre Dame psychologists have discovered: “Entering or exiting through a doorway [...]

Even careful water treatment plants release high quantities of antibiotic-resistant bacteria into the environment — another form of ecological “invasiveness” 0

Think about the implications of this finding The University of Minnesota reported that: While the levels of overall bacteria were still relatively low in the surface water samples, researchers in the University of Minnesota study found that the quantities of antibiotic-resistant genes and human-specific bacteria were typically 20-fold higher at the site where treated wastewater [...]

Deforestation at high latitudes may partially offset global warming — if other probable complexities are not taken into account 0

Let’s not tell Earth-ravaging Right Wing Deniers A Yale-led study indicates that deforestation increases northern latitude albedo, resulting in an overall cooling effect. With dark colored forests gone, solar radiation — which had been absorbed by the comparatively darker trees — is now reflected by lighter colored, often snow-covered, ground. Even at night, open land [...]
