Researchers have discovered that they can control the stickiness of adhesive bandages using ultrasound waves and bubbles. This breakthrough could lead to new advances in medical adhesives, especially in cases where adhesives are difficult to apply such as on wet skin.


Scientists have long known that while listening to a sequence of sounds, people often perceive a rhythm, even when the sounds are identical and equally spaced. One regularity that was discovered over 100 years ago is the Iambic-Trochaic Law: when every other sound is loud, we tend to hear groups of two sounds with an initial beat. When every other sound is long, we hear groups of two sounds with a final beat. But why does our rhythm perception work this way?

Whether it is dancing or just tapping one foot to the beat, we all experience how auditory signals like music can induce movement. Now new research suggests that motor signals in the brain actually sharpen sound perception, and this effect is increased when we move in rhythm with the sound.
