Research by Jeanne Brown, a graduate student at McGill University, found that men use vocal fry more than women, contrary to the popular stereotype. Vocal fry is a speech pattern characterized by a drop in pitch, usually at the end of sentences. The findings were presented at the Acoustical Society of America meeting in Philadelphia.

Olympic weightlifters exploit the 'whip' of a barbell to gain an advantage, scientists study the physics behind it. Joshua Langlois conducted a modal analysis to quantify the whip and understand its mechanics. The study involved suspending barbells and measuring their vibrations.
