The perfect pour: Model predicts beer head features

Researchers have analyzed brewing with numerical simulations to predict an array of beer foam features. They demonstrate that their model can determine foam patterns, heights, stability, beer/foam ratio, and foam volume fractions. The study presents th…

The ‘tipping point’ toward Alzheimer’s

Scientists are not yet clear on how the tau protein changes from a benign protein essential for normal function in our brains into the toxic neurofibrillary tangles that are a signature of Alzheimer’s and other neurodegenerative diseases.

Smash or pass? This computer can tell

Could an app tell if a first date is just not that into you? Engineers say the technology might not be far off. They trained a computer to identify the type of conversation two people were having based on their physiological responses alone.

Nightly sleep is key to student success

A multi-institutional team of researchers conducted the first study to evaluate how the duration of nightly sleep early in the semester affects first year college students end-of-semester grade point average (GPA). Using Fitbit sleep trackers, they fou…

Biodiversity engine for fishes: Shifting water depth

Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world’s tropical waters, yet the fish groups that generate new species most rapidly inhabit colder c…
