Sleeping on the job? Actually, that’s a good thing

ANN ARBOR — Employees seeking to boost their productivity at work should take a nap—yes, sleeping on the job can be a good thing.

A new University of Michigan study finds that taking a nap may be an effective strategy to counteract impulsive behavior and to boost tolerance for frustration. (more…)

Cesium atoms shaken, not stirred, to create elusive excitation in superfluid

Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like a fountain.

Future Nobel laureate Lev Landau came along in 1941, predicting that superfluid helium-4 should contain an exotic, particle-like excitation called a roton. But scientists, including Landau, Nobel laureate Richard Feynman and Wolf Prize recipient Philippe Nozières have debated what structure the roton would take ever since. (more…)

Small Business Owners Not Always Worried about Being Treated Fairly, MU Researcher Finds

Small retailers willing to sacrifice fairness for success

COLUMBIA, Mo. – Fairness is not always the most important priority for small retailers. In an international study, University of Missouri researchers found that some small retailers are less concerned about whether they are treated fairly by business suppliers than other factors, such as cash flow and company survival.

Brain’s response to sexual images linked to number of sexual partners

UCLA researchers say finding could lead to strategies to reduce risky sex

Like most things, sex requires motivation. An attractive face, a pleasant fragrance, perhaps a sexy image. Yet people differ in their response to sex cues, some react strongly; some don’t. A greater responsiveness to sexual cues might provide greater motivation for a person to act sexually, and risky sexual behaviors typically occur when a person is motivated by particularly potent, sexual reward cues.

Attraktive Innenstadtlage beschert Turmfalken eine böse Überraschung

Das Leben in der Innenstadt ist für Turmfalken eine “ökologische Falle”. Durch attraktive Nistplätze in Wiens Altbauten angezogen, kämpfen Turmfalken mit Nahrungsmangel. Dies fand ein Team um die Zoologin Petra Sumasgutner von der Universität Wien heraus. Im Rahmen einer Studie wurden über 400 Turmfalken-Nester in Wien über Jahre beobachtet. Ergebnis: Die Nachkommen der in der Innenstadt brütenden Turmfalken haben weniger Überlebenschancen, weil es an tagaktiven Beutetieren mangelt. Aktuell erschien dazu eine Publikation im open access journal “Frontiers in Zoology”.

Seit 2010 wird in Wien, initiiert von der Zoologin Petra Sumasgutner, ein Turmfalkenmonitoring durchgeführt. Die vorliegende Studie gibt nun erstmals einen Überblick über das inzwischen umfangreich gesammelte Datenmaterial, und es konnten Rückschlüsse auf die Brutbiologie der Tiere in der Stadt gemacht werden.

A Few Winners, But Many More Losers

Southwestern Bird and Reptile Distributions to Shift as Climate Changes

Dramatic distribution losses and a few major distribution gains are forecasted for southwestern bird and reptile species as the climate changes, according to just-published research by scientists with the U.S. Geological Survey, the University of New Mexico, and Northern Arizona University.

Overall, the study forecasted species distribution losses – that is, where species are able to live – of nearly half for all but one of the 5 reptile species they examined, including for the iconic chuckwalla. The threatened Sonoran (Morafka’s) desert tortoise, however, is projected to experience little to no habitat losses from climate change.  (more…)

Does it pay to be a lover or a fighter? It depends on how you woo females

As mating season approaches, male animals are faced with a question that can make or break their chances at reproducing: does it pay to be a lover or a fighter? Or both?

Researchers from The University of Manchester and Syracuse University in New York working with the University of Western Australia, found that where animals fall on the lover/fighter scale depends on how much they are able to ensure continued mating rights with females.

In species where fighting for the right to mate means greater control of females, such as in the elephant seal, males invest more in weapons and less in testes size. (more…)

Dynamic Impact of Online Learning on Education

Online education is now considered as one of the most dynamic paradigms of learning. It may be a new player in the academic field but it has taken center stage for the past decade.

Today, there are over 7.1 million individuals who have taken part in this innovation. Just imagine, seven million students learning while facing their computers instead of sitting in a classroom. It’s too large a number to imagine, but it’s happening in this very moment. (more…)
