A technology commonly used to map the bottom of the deep ocean can also detect gas seeps in the water column with remarkably high fidelity, according to scientists from the University of New Hampshire and the National Oceanic and Atmospheric Administration (NOAA). This finding, made onboard the NOAA ship Okeanos Explorer in the Gulf of Mexico, will lead to more effective mapping of these gas seeps and, ultimately, enhanced understanding of our ocean environments. The mapping technology,...

In a paper published recently in the journal Science, researchers at Brown University and from the Republic of Georgia have learned how bats can home in on a target, virtually dismissing other objects in their midst. The trick lies in their neurons: Bats can separate a cavalcade of echoes returning from their sonar blasts by distinguishing changes in amplitude "” the intensity of the sound "” between different parts of each echo within 1.5 decibels, to decide whether the object is...
