This research team used a laser sensor originally designed for autonomous vehicles to track debris flow surges.
How to Bend Lightning with a Laser Beam
For the first time, scientists have redirected lightning using a laser beam. And that’s just the start of what’s possible.
Ice Towers May Hold Promise—and Water—for Some Cold, Dry Places
A new study that cues into the formation of ice cones for storing glacial meltwater reveals how the structures can be built more efficiently and which climatic conditions work best.
Mountains Sway to the Seismic Song of Earth
The Matterhorn in the Swiss Alps is in constant motion, gently swaying back and forth about once every 2 seconds.
Decadal Changes in Glacial Discharge in the High Alps
A new statistical analysis of daily, glacial runoff cycles offers a unique way of examining how Alpine glaciers have responded since the onset of rapid regional warming in the 1980s.
Ancient Romans Polluted Their Lakes Just Like We Do Today
Sediments from a lake in Switzerland reveal that ancient Romans triggered dead zones caused by the runoff of nutrients. Sound familiar?
Peering Beneath the Powder: Using Radar to Understand Avalanches
High-resolution radar images from Switzerland’s experimental test site show that snow temperature is a key factor in classifying avalanche behavior.
How the Micrometeorology of Alpine Forests Affects Snowmelt
A field study in the Swiss Alps showed considerable spatial and temporal variability in forest air and surface temperatures, with implications for snowmelt models.
New Technique Could Help Scientists Track Nitrous Oxide Sources
A long-term study in Switzerland reveals the promise of a new method to determine isotopic composition of the potent greenhouse gas.
Boulders Limit Transport of Sand and Gravel in Steep Rivers
Mountain rivers and streams actively reshape landscapes by eroding material from uplands and depositing it in lowlands. Scientists can now predict this transport in very steep streams.
