- Drops of water hitting the ground cause geosmin to be released into the air, making it much more abundant after a rain shower. "Lots of animals are sensitive but human beings are extremely sensitive to it," added Prof Buttner.

Mar 17, 2024 · Did you know that cattle, like many animals, have a much stronger sense of smell than humans? In comparison to humans, cattle can detect much smaller differences in odor concentration. Cattle select their food based on smell, that’s why sometimes you can see them sorting through the feed ration.
Aug 8, 2024 · Go to a farm or ranch to observe and study actual cattle behaviour. Make sure the animals cannot see or smell you, otherwise they will come up to the fence and stare at you, expecting some form of treat, or run away where you cannot observe them.

Geosmin is the primary compound responsible for the smell of rain. The word stems from the Greek words geo (earth) and osme (smell). Geosmin is a bicyclic alcohol produced by certain blue-green algae (cyanobacteria) and bacteria (mainly Actinomyces, such as Streptomyces). The compound has an earthy, musty, or muddy scent. Humans are highly sensitiv...
Lightning is the main source of the ozone scent of a thunderstorm. The energy of a lightning strike breaks the chemical bonds that hold nitrogen (N2) and oxygen (O2) molecules together. Some of the oxygen molecules combine and form ozone (O3). While a small amount of ozone in air smells like rain, too much is unhealthy and causes health effects, su...
Plants release oils during dry spells that protect them from loosing too much water and also deposit on the ground and prevent seed germination. This minimizes the chance of seedlings sprouting and then dying from lack of moisture. When rain falls, these oils splash up and enter the air, adding another earthy component to petrichor. The principal o...
- They Feel Threatened. With their keen sense of hearing, cows can pick up on predator sounds humans cannot hear. This causes them to feel threatened, and they will moo to let the other cows know there is potential danger.
- They’re Looking for Their Calves. If mother cows cannot find their calves, they will moo loudly to locate them. The calf will usually respond with its moo so that the two can find each other.
- They’re Hungry. Cows have a four-chamber stomach that needs to be constantly filled with food. When they are hungry, they will inform the other cows by mooing.
- They’re Thirsty. Like humans, cows need to drink water to stay alive. When thirsty, they will moo to let the other cows know and then head to the nearest water source.
Apr 3, 2021 · The familiar aroma fills the air when rain falls after long periods of warm, dry weather. It’s called petrichor and, it turns out, humans are very sensitive to it. This article explores the science behind petrichor and the main compound responsible for the smell – geosmin.
Sep 2, 2018 · People call it musky, fresh – generally pleasant. This smell actually comes from the moistening of the ground. Australian scientists first documented the process of petrichor formation in...
