View ArticleWhat's the sound of a hundred thousand soccer fans?
Mention vuvuzela to soccer fans, and they may cringe. The plastic horn rose to prominence during the 2010 World Cup in South Africa, where tens of thousands of those instruments blared in packed...
View ArticleNew seismic survey technique could save dolphins' hearing
Conventional seismic imaging transmits sound energy into the ground and builds a picture of the underlying geology by analysing how the energy waves are reflected back to the receiver.
View ArticleRadio astronomers develop new technique for studying dark energy
Pioneering observations with the National Science Foundation's giant Robert C. Byrd Green Bank Telescope (GBT) have given astronomers a new tool for mapping large cosmic structures. The new tool...
