New models to explore the microstructure of polymer mixtures

A well-known method for making polymer materials is to blend or mix multiple polymers. For disperse blends, two liquid polymers do not mix well with each other, leading to a so-called droplet-in-matrix microstructure which ...

Ranked choice, multimember districts blunts gerrymandering

New research from the College of Engineering lays out in detail why ranked-choice voting, combined with multi-member legislative districts, promotes fair representation, particularly when it comes to blunting gerrymandering—the ...

Diversity matters: Species richness keeps ecosystems running

Microorganisms, plants, and animals accomplish great feats every day. For example, by decomposing material, producing plant biomass, or pollinating flowers, they keep nature 'up and running," thereby securing the livelihood ...

All-female crew in water-tank spaceflight study

This week 20 women are tucking themselves in a waterbed for five days as part of a dry immersion study to recreate some of the effects of spaceflight on the body. The campaign kicked off yesterday with the first two subjects ...

New heat exposure model can protect citizens

Increasingly extreme heat threatens the health and comfort of city dwellers. That's why researchers from the University of Georgia have developed a new dynamic heat exposure index that captures varying heat exposure within ...

Deepwater renewal in Lake Geneva in light of climate change

EPFL scientists have studied two mechanisms that can help bring oxygen to the depths of a lake—essential for preserving the lake's ecosystem. The classical deepwater renewal caused by surface cooling during winter is becoming ...

Applying game-based learning to animal disease preparedness

Fifty years ago, the strategy-based game Oregon Trail hit classrooms around the country. Anyone who has played the game knows that crossing a river in the wrong place at the wrong time or other poor decisions along the trail ...

New agreements needed now to improve food systems

In 2020, between 720 and 811 million people suffered from hunger, and almost as many (768 million) were malnourished. Two billion people did not get enough essential nutrients and vitamins due to unbalanced diets or a lack ...

Himalayan hydropower 'clean but risky,' warn scientists

With its steep topography and abundant water resources the Himalayas offer sustainable, low-carbon hydropower for energy-hungry South Asia. But there is a catch—the mountain range falls in one of the world's most seismically ...
