Caroline DeLong, an assistant professor of psychology at Rochester Institute of Technology, is researching object discrimination in goldfish and echolocation in dolphins to bring scientists closer to unlocking the mysteries of animal perception and cognition. (PRWEB) October 25, 2011 The fictitious storybook character Dr. Doolittle was known for talking with animals. Caroline DeLong, an assistant professor of psychology at Rochester Institute of Technology, is a real-life Doolittle whose...

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,...

Bats Have Fastest Known Mammal Muscle

Bats derive their ability to use echolocation, the bouncing of sound waves off objects to produce an accurate representation of the environment in total darkness, from so-called “superfast” muscles, researchers reported in latest issue of the journal Science. These superfast muscles, which are located in the bats´ larynx, are a physical trait never before seen in mammals, and allow the bate to make a rapid series of calls as they home in on their prey.   They...

A new study reveals that the way fruit bats use biosonar to 'see' their surroundings is significantly more advanced than first thought. The study, published September 13 in the online, open access journal PLoS Biology, examines Egyptian fruit bats (Rousettus aegyptiacus), which use echolocation to orient inside their caves and to find fruit hidden in the branches of trees. Their high-frequency clicks form a sonar beam that spreads across a fan-shaped area, and the returning echoes allow them...

  Researchers at the Woods Hole Oceanographic Institution (WHOI) have calculated the flow rate of the BP Macondo well to be about 57,000 barrels of oil per day, totaling close to 5 million barrels of oil and nearly 100 million standard cubic feet per day of natural gas released from April 2010 to July 2010. The study results were published in the online issue of the Proceedings Of The National Academy Of Sciences (PNAS). The estimates matched those made by the federal government...
