Study 'cracks' mystery of water-promoted fracture growth on glass

Glass windows often endure external environmental factors such as wind, rain, and humidity, which lead to the formation of microcracks in their surface. For instance, a gust of wind can propel sand onto a window and create ...

Heat conduction is important for droplet dynamics

For driving in the rain, it's preferable that the raindrops roll or bounce off the windshield instead of coating it or even freezing. A team of engineers in the McKelvey School of Engineering at Washington University in St. ...

Coughing downward reduces spread of respiratory droplets: study

With many people heading indoors for the winter months and respiratory droplets acting as a major contributor to COVID-19 spread, the scientific community has renewed interest in the dynamics behind how they spread. Modeling ...

Lipid droplets as endogenous intracellular microlenses

With the demand in real-time monitoring of endoplasmic variations and rapid detection of extracellular signals, a great number of approaches to bioimaging have been developed. The past few decades have witnessed a dramatic ...

How a floating fern withstands rain

The tropical floating fern Salvinia molesta has developed sophisticated structures to allow water to roll off its leaves quickly—even during heavy rainfall. This relieves the pressure on the leaves floating on the water ...

Can oil and water mix?

Common experience tells us that oil and water do not mix. Yet, it turns out that they can mix when oil is dispersed as small droplets in water. This strange behavior has long vexed scientists because there is no explanation ...

Researcher pushes limit of when water will freeze

Though it is one of the great mysteries of science, the transformation of water into ice often escapes people's minds as it is just assumed that's what happens. But how and why it happens is the subject of intense scrutiny by ice ...

How molecular clusters in the nucleus interact with chromosomes

A cell stores all of its genetic material in its nucleus, in the form of chromosomes, but that's not all that's tucked away in there. The nucleus is also home to small bodies called nucleoli—clusters of proteins and RNA ...
