This makes rat removal in Walnut and West Covina...

Promiscuous Female Mice Have Sexier Sons
2013-11-19 07:35:02

University of Utah Males make more pheromone if mama had access to many mates University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, but smelling sexier shortens their lives. "If your sons are particularly sexy, and mate more than they would otherwise, it's helping get your genes more efficiently into the next generation,"...

How Mice And Rats Developed A Unique Masticatory Apparatus Making Them Evolutionary Champions
2013-10-28 13:02:40

European Synchrotron Radiation Facility The subfamily of rodents known as Murinae (mice, rats, etc.), which first appeared in Asia 12 million years ago, spread across the entire Old World (Eurasia, Africa, Australia) in less than 2 million years, a remarkably fast rate. Researchers have long suspected that one of the reasons for their evolutionary success is related to their unique masticatory apparatus. Now, researchers have used the brilliant X-ray beams produced at the European...

Oreos Addictive As Drugs To Rats
2013-10-16 08:44:25

Michael Harper for redOrbit.com - Your Universe Online Neuroscience students from Connecticut College who fed rats “America’s Favorite Cookie” now say Oreos are just as addictive as cocaine and morphine for the lab animals. Rats that were fed the cookies not only went straight to the creamy center first, they also lingered in the area where they were usually fed the cookies. Furthermore, the researchers found that eating Oreos activated even more neurons in the rats’ brains'...

Safe Sugar Dose In Humans Proves Toxic To Mice
2013-08-13 15:45:07

Brett Smith for redOrbit.com - Your Universe Online Using a novel study approach, researchers at the University of Utah found a high-sugar diet considered borderline-safe for human consumption can increase mortality and reduce vigor in mice. Researchers said the sugary diet had a similar effect to being the inbred offspring of first cousins in the mice they observed. "Our results provide evidence that added sugar consumed at concentrations currently considered safe exerts dramatic...

Increased rainfall this season has led to an increase in mouse infestations. Horne’s Pest Control can advise on the best methods for ridding homes of this destructive pest. Martinez, GA (PRWEB) August 02, 2013 Rain may make flowers grow and crops more plentiful, but it also can play a significant role in bringing rodents indoors. According to the National Weather Service, Georgia, and in particular Augusta, has seen rainfall of record proportions. All this rain has increased the amount...

Rodents recognize objects using sophisticated perceptive strategies Sight is such a spontaneous activity that we are unaware of the complexity of the brain mechanisms it implies. For instance, we easily recognize objects, which appear to look always the same, without realizing that we observe them from ever-changing points of view and that their image — the luminance profile cast onto the retina —varies significantly each time we look at them. To maintain such "invariance"...

Rats Sniff To Communicate Complex Social Information
2013-03-08 09:43:34

April Flowers for redOrbit.com - Your Universe Online Checking out their environment by sniffing is a common behavior for dogs, cats and a number of other mammals. A new study from Case Reserve University School of Medicine reveals that sniffing also serves as a method of communication in rats. This unexpected discovery may help to identify brain regions critical for interpreting communication cues as well as help identify which brain malfunctions can lead to complex social...

Women More Talkative Than Men Because Thier Brain Is Designed That Way
2013-02-22 12:17:19

Michael Harper for redOrbit.com — Your Universe Online We´ve all heard the oft-repeated statistics about women talking more than men. And to back up those statistics, one previous study has shown that a part of the brain responsible for processing communication is simply larger in a woman than a man. Now, a new study adds to those claims by moving a step further, showing that the female brain is actually designed with communication in mind. Performed by doctors at the...

Running The Rat Race: Observing Their Aerobic Capacity
2013-01-16 18:20:11

Alan McStravick for redOrbit.com — Your Universe Online Last month, at the Wellcome Trust´s conference on ℠Rat Genomics and Models´, several different and interesting ongoing studies were presented to all in attendance. One study in particular, out of the University of Michigan (U of M), sought to explain how selectively bred rat models were able to yield both high and low capacity runners (HCR and LCR) and just what the implications, genetically, these models might...
