As your underclothes rub against your skin, the fluff ratchets its way up to …
To some extent, yes. Psychologists have tested this in various ways, including asking people to spend time learning pairs of words, and then asking them to deliberately forget some of them. Future memory for the deliberately forgotten words tends to be poorer. More recently, researchers have extended this concept to show that people can unlearn behavioural habits acquired in the lab (such as particular …

A 1998 study at the University of Utah found that this can mean women …
This hybrid drone combines four sets of blades (as found on a quadcopter) with a ’flying wing’ design, meaning you get the high speeds possible with the latter, combined with the vertical take-off and landing and hovering capabilities of the former.

The controller unit analyses the timbre and levels of ambient sound in the room, then instructs …
