Long-term Himalayan glacier study

The glaciers of Nanga Parbat – one of the highest mountains in the world – have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study. The geographers combined historical photographs, surve…

Researchers discover the physics of foams

Chemical engineers have answered longstanding questions about the underlying processes that determine the life cycle of liquid foams. The breakthrough could help improve the commercial production and application of foams in a broad range of industries.

Excess nitrogen puts butterflies at risk

Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation — to the detriment of the butterflies, as researchers have discovered.

Novel chirped pulses defy ‘conventional wisdom’

Researchers demonstrate highly chirped pulses created by a using a spectral filter in a Kerr resonator, enabling them to widen a laser pulse wavefront by separating the beam’s colors. The chirped pulses remain stable even with more than 90% energy loss.
