A home to friendly weirdos. The Grey Gardens of the Fediverse (but beige). Occasionally graphically cacographic. Definitely probably not a cult (though you'll never be 100% sure). Beige-bless 🙏

Your cells can hear
Uncovering the relationship between life and #sound

There's a sensation that you experience -- near a plane taking off or a speaker bank at a concert -- from a sound so total that you feel it in your very being. When this happens, not only do your brain and ears perceive it, but your cells may also.

EurekAlert!Your cells can hearKyoto, Japan -- There's a sensation that you experience -- near a plane taking off or a speaker bank at a concert -- from a sound so total that you feel it in your very being. When this happens, not only do your brain and ears perceive it, but your cells may also. Technically speaking, sound is a simple phenomenon, consisting of compressional mechanical waves transmitted through substances, which exists universally in the non-equilibrated material world. Sound is also a vital source of environmental information for living beings, while its capacity to induce physiological responses at the cell level is only just beginning to be understood. Following on previous work from 2018, a team of researchers at Kyoto University have been inspired by research in mechanobiology and body-conducted sound -- the sound environment in body tissues -- indicating that acoustic pressure transmitted by sound may be sufficient to induce cellular responses.

Two small experiments with Japanese students found that both male and female faces were perceived as more dominant when viewed against a red background, as compared to a green or gray background. Geometric shapes were also assessed to be more dominant when presented against a red background.

People interpret dogs' emotions based on context. When shown a picture of a dog adjacent to a leash, they interpret the dog as being happy; when the same picture is manipulated to show the dog adjacent to a vacuum cleaner, they interpret the dog as being unhappy.

Knowridge Science Report · Are we misreading our dogs? New research says yesMany dog owners believe they can easily understand their pets’ emotions. A wagging tail means happiness, a guilty look means regret, and a lowered head means sadness. But new research from Arizona State University suggests that humans often misread their dogs’ emotions. The study, published in Anthrozoös, found that people judge their dog’s emotions based […]

Do we all see red as the same colour? We finally have an answer

It is impossible for us to know exactly how another person's experience of the world compares to our own, but a new experiment is helping to reveal that colour is indeed a shared phenomenon
