Imagine you’re swimming lazily along, just below the water’s surface in a tropical ocean. You look down at a colorful array of pinks, yellows and greens. Spikey corals cover the floor below. Small fish swim in and out of hiding places, ducking behind the stationary animals to avoid your peering eyes.

Super hearing: University of Toronto scientists study fly to develop better hearing aids
Ormia ochracea's sense of directional hearing is second to none in the animal kingdom.
“These flies have highly specialized ears that provide the most acute directional hearing of any animal,” says Andrew Mason, an associate professor of biology at U of T Scarborough. “The mechanism that makes their hearing so exceptional has even led to a range of bio-inspired technology, like the mini-directional microphones used in hearing aids.”
Scientists Study Atmospheric Waves Radiating out of Hurricanes
Researchers believe they have found a new way to monitor the intensity and location of hurricanes from hundreds of miles away by detecting atmospheric waves radiating from the centers of these powerful storms.
Rare Footage Helps Explain What Narwhals Use Their Tusks For
Scientists are marveling over never-before-seen footage of narwhals that has brought to light new evidence for what those unicorn-like tusks are actually used for.
Cities need to "green up" to reduce the impact of air pollution on residents as well as buildings
The study, just published in the journal Atmospheric Environment, points out that low hedges reduce the impact of pollution from vehicles in cityscapes where there are large buildings close to roads, far more effectively than taller trees. In some environments, trees actually make the pollution more concentrated depending on prevailing wind conditions and built-up configurations.
3D-printed soft four legged robot can walk on sand and stone
Engineers at the University of California San Diego have developed the first soft robot that is capable of walking on rough surfaces, such as sand and pebbles. The 3D-printed, four-legged robot can climb over obstacles and walk on different terrains.
Researchers led by Michael Tolley, a mechanical engineering professor at the University of California San Diego, will present the robot at the IEEE International Conference on Robotics and Automation from May 29 to June 3 in Singapore. The robot could be used to capture sensor readings in dangerous environments or for search and rescue.
