Cats have numerous muscles controlling their external ears, allowing them to turn and reposition each ear with remarkable precision.
The ears can move toward different sounds and help cats determine where noises originate without requiring the...
Not every beach is made from the same type of material. Sand can originate from weathered rocks, volcanic material, shells, coral fragments, and other biological material.
Ocean waves and currents continually sort, transport, and reshape these...
Certain plants noticeably change the position of their leaves according to the day-night cycle.
This movement is called nyctinasty. Leaves may fold together, droop, or rise as light conditions change, with internal biological rhythms also...
Humans rely heavily on sweating across the skin, while dogs primarily regulate excess body heat through panting.
Evaporation from moist surfaces in the respiratory system helps release heat. Dogs do have sweat glands associated with their paw...
Window coverings influence how sunlight and heat enter and leave a room.
Closing suitable curtains or other window treatments during periods of strong sunlight can reduce unwanted solar heat entering through windows. During colder conditions...
Cats don't rely only on their noses to investigate smells. They also have a vomeronasal organ, sometimes called Jacobson's organ, that helps detect certain chemical signals.
A cat investigating an interesting scent may briefly hold its mouth...
For many flowering plants, removing faded flowers—a gardening practice called deadheading—can redirect resources away from seed production.
In species that respond well to the technique, this can encourage the plant to continue producing flowers...
A seed doesn't always begin growing as soon as water becomes available. Many species have dormancy mechanisms that delay germination until environmental conditions become suitable.
Depending on the plant, germination may require particular...
A cat's eyes can provide social signals in addition to vision. Research has found that slow narrowing and blinking of the eyes can play a role in positive cat-human interactions.
Cats were observed responding differently when humans performed...
