Environmental DNA analysis to manage fecal contamination

"Who's peeing in the water?" Unlikely as it may seem, there is a great deal of science behind this question. Determining the source of fecal contamination—an important public health issue—requires years of research. Doctoral ...

Revealing new states in 2D materials

Atomically thin two-dimensional (2D) materials can provide highly interesting excitonic properties, which render them an attractive platform to explore polaritonic physics.

NASA develops technology to dissect the lower atmosphere

The part of the atmosphere closest to the planet is the hardest to measure from space due to the volume of gases above it. Studying Earth's planetary boundary layer, or PBL, will enable scientists to better understand the ...

Swiss rivers on track to overheat by the end of the century

According to an EPFL study, if we take immediate measures to reduce CO2 emissions, we could limit the rise in the temperature of Swiss rivers to 1 degree Celsius between now and 2090 without drastically affecting their discharge. ...

Mosquitoes might be attracted to certain colors

There's no question that finding yourself covered in mosquito bites quickly takes the shine off a pleasant summer evening. But mosquitoes are more than a nuisance. They're also the deadliest creatures on Earth, owing to the ...

What bird beaks say about tropical biodiversity

Areas of the globe where fruit-eating birds have wider beaks also have larger palm fruits, a new study shows. This sounds banal, but it provides new insights into tropical biodiversity and clues for solving species conservation, ...

Comparing machine learning models for earthquake detection

Machine learning is transforming data-heavy fields across the sciences, and seismology is no exception. Several machine learning methods have emerged for earthquake detection, phase identification, and phase picking. However, ...
