Sense Of Smell In Mice Restored From Gene Therapy
2012-09-07 14:10:09

A team of scientists from Johns Hopkins and other institutions report that restoring tiny, hair-like structures to defective cells in the olfactory system of mice is enough to restore a lost sense of smell. The results of the experiments were published online this week in Nature Medicine, and are believed to represent the first successful application of gene therapy to restore this function in live mammals. An expert in olfaction, Randall Reed, Ph.D., professor of molecular biology and...

Brett Smith for redOrbit.com — Your Universe Online Researchers from Michigan State University working in Kenya have shown for first time that groups of hyenas possess different odor-producing bacterial communities within their scent glands that they use to communicate everything from age to social status. “A critical component of every animal´s behavioral repertoire is an effective communication system,” said Kevin Theis, an MSU molecular biologist. “It is...

Is sleep learning possible? A new Weizmann Institute study appearing today in Nature Neuroscience has found that if certain odors are presented after tones during sleep, people will start sniffing when they hear the tones alone — even when no odor is present — both during sleep and, later, when awake. In other words, people can learn new information while they sleep, and this can unconsciously modify their waking behavior. Sleep-learning experiments are notoriously difficult to...

Gene Mutation In Male Moth Allows It To Detect Female Even When Scent Is Altered
2012-08-15 13:54:51

Brett Smith for redOrbit.com - Your Universe Online Because of a single gene mutation on the antenna of a male moth, he is able to receive a female moth´s Hail Mary pheromone pass from end zone-to-end zone even if she were to alter its scent. According to a report published this week in the Proceedings of the National Academy of Sciences (PNAS), a team of researchers led by Montana State University entomologist Kevin Wanner identified the gene in male moths responsible for...

What’s That Smell? Space of Course!

Lee Rannals for redOrbit.com - Your Universe Online While most of us on Earth are more curious about what it´s like working in an environment without gravity, a new curious element of the abyss has risen up.  What is that smell? As astronauts return from spacewalks, they enter the airlock, remove their helmets, and are overwhelmed by a peculiar smell. According to the account of a few astronauts who have experienced this, space apparently smells.  The aroma space...

Just a Drop is an innovative, bathroom odor product that eliminates embarrassing personal toilet odors before they enter the air. White Plains, NY (PRWEB) July 09, 2012 Just a Drop, an innovative bathroom odor product that actually eliminates embarrassing personal odor rather than just masking it, is experiencing record sales. On July 2, 2012, a popular talk show host, on his national television show, demonstrated the science behind how Just A Drop works. In addition, celebrities and...

Odor Perception In Terrestrial Hermit Crabs Increased By Humidity
2012-07-05 09:13:27

Olfaction in land crabs is still in an early transitional stage between life in water and on land Max Planck scientists have found out that the olfactory system in hermit crabs is still underdeveloped in comparison to that of vinegar flies. While flies have a very sensitive sense of smell and are able to identify various odor molecules in the air, crabs recognize only a few odors, such as the smell of organic acids, amines, aldehydes, or seawater. Humidity significantly enhanced electrical...

Male Virgin Moths Think They're Hot When They're Not
2012-06-07 09:12:58

Female sex odor makes cool males take flight too soon Talk about throwing yourself into a relationship too soon. A University of Utah study found that when a virgin male moth gets a whiff of female sex attractant, he's quicker to start shivering to warm up his flight muscles, and then takes off prematurely when he's still too cool for powerful flight. So his headlong rush to reach the female first may cost him the race. The study illustrates the tradeoff between being quick to start...

Michael Harper for RedOrbit.com More news was made this week in the ongoing struggle between the classes. No, not the wealth classes or the classes of status: The classes of age. We´ve all been a part of this struggle and have seen it played out first hand. The younger class – say, ages 20 and up – are just ready to, like, live their life, you know? They can´t be bothered when “the man” tries to bring them down. Then there´s the class of the...

(Ivanhoe Newswire) -- Does your grandma really have that "grandma scent" that you think that she does? New research says yes! The study conducted by Monell Center shows that humans can identify the age of other humans based on differences in body odor. "Similar to other animals, humans can extract signals from body odors that allow us to identify biological age, avoid sick individuals, pick a suitable partner, and distinguish kin from non-kin," senior author Johan Lundstrom, a sensory...
