Can I smell my own pheromones?

Everyone has their own scent—just think of how differently your grandma and your boyfriend smell when you lean in for a hug. But can we smell ourselves? For the first time, scientists show that yes, we can, ScienceNOW reports. Our basis of self-smell originates in molecules similar to those animals use to chose mates.

Everyone has their own scent—just think of how differently your grandma and your boyfriend smell when you lean in for a hug. But can we smell ourselves? For the first time, scientists show that yes, we can, ScienceNOW reports. Our basis of self-smell originates in molecules similar to those animals use to chose mates. Humans use these molecules, called histocompatibility complex proteins, to help differentiate between people and between our own cells and invading pathogens. These peptides were featured in the now-famous “smelly T-shirt” experiment in which researchers asked women to sniffed men’s worn shirts and identify which they preferred. The women tended to select the men’s scents that least like their own smells. But that experiment didn’t reveal how people react to their own smell or even whether they could recognize it. In this latest experiment, biologists tested whether women can recognize lab-made proteins resembling their own. After taking a shower, the researchers asked the women to apply two different solutions to their armpits and decide which smell they liked better. Women who were nonsmokers and who did not have a cold preferred the solution closest to their own scent. Next, the biologist used fMRI to measure brain changes in women while they smelled various solutions. Again, the women responded differently to the self and non-self smells. A particular region of the brain activated only when the women’s “self” peptides came into contact with their nose. These findings may explain how we choose a perfume or cologne. People might select a scent that amplifies their own peptides’ smell, while still being able to appreciate other scents on other people. Chanel No. 5 may mesh well with your own body odor, while your best friend may be better suited for patchouli oil.

Do people hunt musk ox?

muskox hunting seasons are open in certain areas of Alaska, a number of Canadian provinces including Nunavut, and Greenland. In the second part of the XX century muskox were reintroduced to Russia and can now be hunted there as well.

Why hunt Muskox?

Humans hunted muskox ever since the first hunter gatherers colonized the Arctic, and probably never ceased to be amazed by the adaptations of the species to the harsh climate of the tundra. The length of the muskox hair has to be seen to be believed; as one explorer put it, you have a goat-sized animal in a bull-sized cloud of fur. Muskox are herd animals who react to danger by “circling the wagons”, with calves in the middle, and the rest of the herd with their backs to them, and sharp horns directed to the predator. This strategy works well against polar wolves, made muskox extra vulnerable to meat hunters, and presents a challenge to trophy hunters – how on earth are you going to separate the big bull you’re after? Mature bulls feature a great, well-developed boss, that can be as intimidating to behold as any Cape Buffalo. These horns will be a long-lasting symbol of a journey to the wild and beautiful Arctic.
