Counter-Rotation Inside a Glass of Beer Shaken Stirringly

A round of surprise appears in a glass of beer—or a glass of coffee or tea—when you shake it stirringly. Details are in this study: “Counter-Rotation in an Orbitally Shaken Glass of Beer,” Frédéric Moisy, J. Bouvard, and Wietze Herreman [pictured below], EPL [Europhysics Letters], vol. 122, no. 3, no. 34002, 2018. The authors, at Université […]

Did You Smell the Coffee? [In the Footsteps of the Invisible Gorilla]

Charles Spence (Ig Nobel Prize winner for the electronically-modified-sound-of-a-potato-chip experiment) and a colleague have a new study that explores an unexplored aspect—smell—of what’s known as “inattentional blindness.’ Inattentional blindness became widely noticed because of the “invisible gorilla experiment” that won an Ig Nobel Prize for Chris Chabris and Dan Simons.

Further physics insight from walking backwards with coffee

“The authors derive their inspiration from an Ig Nobel prize-winning paper describing a basic mechanical model that investigates the results of walking backwards while carrying a cup of coffee.” So says the report “Mathematical model reveals solution to sloshing coffee,” in Phys.org. The Ig Nobel Prize-winning paper about walking backwards while carrying a cup of coffee […]

Coffee Intake and Incidence of Erectile Dysfunction [research study]

A new study about erectile dysfunction suggests — and also does not suggest — that drinking decaffeinated coffee ups a person’s risk of having erectile dysfunction, especially if the person is a male. The study is: “Coffee Intake and Incidence of Erectile Dysfunction,” David S. Lopez, Lydia Liu, Eric B. Rimm, Konstantinos K. Tsilidis, Marcia de […]

Effect of Explosion-Puffed Coffee on Fruit Flies [research study]

Fruit flies can be measurably affected by explosion-puffed coffee, suggests this new study: “Effect of Explosion-Puffed Coffee on Locomotor Activity and Behavioral Patterns in Drosophila melanogaster,” Bong Soo Ko, So Hyun Ahn, Dong Ouk Noh, Ki-Bae Hong, Sung Hee Han, and Hyung Joo Suh, Food Research International, epub 2017.

Six Cups of Coffee Goes to Your Head, for Surgical Guidance [research study]

A special hat filled with six cups’ worth of ground coffee may make it easier for surgeons to succeed at some kinds of nose and throat surgery. This study presents the news: “Coffee: the key to safer image-guided surgery—a granular jamming cap for non-invasive, rigid fixation of fiducial markers to the patient,” Patrick S. Wellborn […]

Schmutz: White Wine Invites Melanoma, and Coffee Discourages It?

Drinking alcohol — specifically, drinking white wine — may increase your change of getting melanoma, but drinking coffee may decrease your chance. That’s what this new study suggests. The study does not suggest, though we do, that you spend a few minutes exploring the ways that someone might find seemingly interesting things by the process […]
