Strange but True: Shape of Glass Affects How Fast You Drink

Because drinkers monitor their intake with reference to the halfway line of a glass, drinking speed varies depending on the shape of the glass. 

What's the Latest Development?

British researchers have determined that the shape of your beer glass affects how quickly you imbibe you draught, which may influence public health campaigns of the future (and how alcohol sellers market their product). In an experiment, 160 college undergraduates were asked to drink beer and lemonade from straight-sided glasses and flutes, which curve outward toward the lip. "A full straight glass of beer was polished off in 11 minutes, on average. A full flute, by contrast, was down the hatch in seven, which was also the amount of time it took to drink a full glass of lemonade, regardless of the type of vessel."

What's the Big Idea?

University of Bristol researcher Dr. Angela Atwood, who led the study, hypothesizes that beer drinkers who wish to pace themselves through the evening monitor the amount of beer remaining in their glass, likely by referencing the halfway mark. "A curved-sided glass, though, makes exercising such judgment hard—as she demonstrated by calling her volunteers back a week later and asking them to estimate from pictures how full various glasses were." The results of the study may provide public health officials and brewers with contrasting conclusions about what type of glass is best to serve up a beer.

  • The field of plant neurobiology studies the complex behavior of plants.
  • Plants were found to have 15-20 senses, including many like humans.
  • Some argue that plants may have awareness and intelligence, while detractors persist.

Vaping changes blood vessels after one use, even without nicotine

E-cigarettes may be safer than traditional cigarettes, but they come with their own risks.

  • A new study used an MRI machine to examine how vaping e-cigarettes affects users' cardiovascular systems immediately after inhalation.
  • The results showed that vaping causes impaired circulation, stiffer arteries and less oxygen in their blood.
  • The new study adds to a growing body of research showing that e-cigarettes – while likely safer than traditional cigarettes – are far from harmless.

Space is dead: A challenge to the standard model of quantum mechanics

Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.

  • Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
  • In nature, properties of Particle B may be depend on what we choose to measure or manipulate with Particle A, even at great distances.
  • In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
