When cannibals ate brains of people who died from prion disease, many of them fell ill with the fatal neurodegenerative disease as well. Likewise, when cows were fed protein contaminated with bovine prions, many of them developed mad cow disease. On the other hand, transmission of prions between species, for example from cows, sheep, or deer to humans, is—fortunately—inefficient, and only a small proportion of exposed recipients become sick within their lifetimes. A study published on...

Southern California's leader in gopher and mole control has released a free website for readers to get insight to controlling these burrowing animals. Rodent Guys charges no fee to readers and information is based on their years of experience controlling these pests. Cambria, CA (PRWEB) March 22, 2013 Gopher and mole removal is the most difficult pest control for homeowners to tackle by themselves. Both animals live underground and are rarely seen. These menacing pests destroy the...

Hormone Helps Keep Married Men Away From Unknown Attractive Woman
2012-11-14 12:11:19

Lawrence LeBlond for redOrbit.com - Your Universe Online It´s only natural that married men continue to check out other attractive women that happen to come into their field of view. Occasionally, some of these men also have a tendency to seek out these women and make contact. And some may even pursue these women further. But now, a new study published in Tuesday´s issue of the Journal of Neuroscience has uncovered a surprising new property of a hormone they say will keep...

  Why different species have dissimilar sets of chromosomes? Why the differentiated species often conserve apparently identical chromosome complements? Furthermore, why, while chromosome rearrangements can considerably change the course of species evolution, certain variation among individuals and populations of some species persists indefinitely? Such questions motivate researchers to compare chromosomes in closely related species. To understand the nature of chromosome changes in...

Animal study suggests having a lifelong mate leads to greater resistance to drug Long-term relationships make the commonly abused drug amphetamine less appealing, according to a new animal study in the June 1 issue of The Journal of Neuroscience. The findings suggest that social bonds formed during adulthood lead to changes in the brain that may protect against drug abuse. Prairie voles are rodents that form lifelong bonds with mating partners. In the new study, researchers directed by Zuoxin...

Surprising TAU research finds common stress levels in social groups Anxiety, or the reaction to a perceived danger, is a response that differs from one animal or human to another "” or so scientists thought. Now researchers at Tel Aviv University  are challenging what we know about stress, and their study has implications for helping clinicians better treat victims of terrorism or natural disasters. Prof. David Eilam and his graduate student Rony Izhar of Tel Aviv University's...

According to evolutionary theory, natural selection favours traits that enhance dispersal of populations to new habitats. The empirical evidence supporting this theory, however, is relatively scarce. A study carried out by researchers from the Faculty of Biological and Environmental Sciences of the University of Helsinki, along with their Swedish colleagues, reports rapid evolution of traits facilitating dispersal in an outer archipelago. The results was published today in the Proceedings of...

Model is expected to help researchers better understand social bonding and impairments to such behavior Researchers at the Yerkes National Primate Research Center, Emory University, have successfully generated the first transgenic prairie voles, an important step toward unlocking the genetic secrets of pair bonding. The future application of this technology will enable scientists to perform a host of genetic manipulations that will help identify the brain mechanisms of social bonding and...

Scientists from the Biological Station of Doñana (CSIC) and the have characterized the population genetic diversity of an animal species (a mouse, in this case) in its whole distribution. This information is essential for developing successful conservation plans for such species. This work was conducted by Alejandro Centeno Cuadros at the Doñana Biological Station (CSIC) in Sevilla, and the Department of Animal Biology of the University of Granada....

U.S. primate researchers say they've used prairie voles as models in understanding early life parent-offspring nurturing impacts on later life relationships. Yerkes National Primate Research Center scientists at Emory University said by influencing early social experience in prairie voles, they have gained greater insight into what aspects of early social experience drive diversity in adult social behavior. Prairie voles are small, highly social, hamster-sized rodents that often form stable,...

Siberian Weasel, Mustela sibirica
2013-01-01 15:35:26

The Siberian weasel or kolonok (Mustela sibirica) is native to Asia. Its native range includes Laos, Myanmar, North Korea, Nepal, India, and Russia, among other areas. It has been introduced into Kamishima, Jabu, Honshu, and Shikoku. This species holds eleven recognized subspecies. The Siberian weasel varies in size between the sexes, with males growing larger than females. Males can reach an average body length of up to 15.3 inches and a weight of up to 1.8 pounds, while females reach a...

Steppe Polecat, Mustela eversmanii
2013-01-01 14:56:56

The steppe polecat (Mustela eversmanii), also known as the masked polecat or the white polecat, is a member of the Mustelidae family that is native to Eastern and Central Europe and Central Asia. It is a nomadic species, moving across its large range to follow its main prey item of ground squirrels. This species holds five recognized subspecies, and one extinct subspecies known as M. e. michnoi. The steppe polecat is similar in appearance to the European polecat, but its body is longer due...

Günther's Vole, Microtus guentheri
2012-08-05 21:09:44

Günther's vole (Microtus guentheri) can be found in many areas including Iran, Bulgaria, Greece, Lebanon, and Turkey, among other areas. It is able to thrive in many habitats, including agriculatal lands and artificial habitats, and at many elevations, depending on the area it inhabits. However, it is fragmented across its range, and populations do fluctuate in some areas. Günther's vole does not have any major threats, but in Libya, the population there is nearing extinction. Because of...

Field Vole, Microtus agrestis
2012-08-05 21:06:26

The field vole (Microtus agrestis) is native to Europe, inhabiting a large range that includes Poland, France, Germany, and Belgium, among many other areas. It is not found in Ireland or in Iceland. It prefers a habitat within moist grasslands, like marshes and woodlands and along riverbanks. The population density of the field vole will fluctuate throughout a four-year period. The field vole will dig burrows underground, but it most commonly builds nests on the surface. It reaches an...

Common Vole, Microtus arvalis
2012-08-05 21:02:11

The common vole (Microtus arvalis) is native to Eurasia, with a very large range stretching across many areas. Its preferred habitat includes all areas besides densely forested areas. It will inhabit agricultural lands, and as a result will end up eating the crops found there, although it prefers grass. The common vole varies slightly in size between sexes, with males weighing an average of 1.7 ounces and females weighing 1.4 ounces if not pregnant. It will inhabit home ranges of up to .3...
