Raising Coral

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.”

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.

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.

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.

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.

How hard did it rain on Mars?

Heavy rain on Mars reshaped the planet’s impact craters and carved out river-like channels in its surface billions of years ago, according to a new study published in Icarus. In the paper, researchers from the Smithsonian Institution and the Johns Hopkins University Applied Physics Laboratory show that changes in the atmosphere on Mars made it rain harder and harder, which had a similar effect on the planet’s surface as we see on Earth.

Extreme weather has greater impact on nature than assumed

An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Philosophical Transactions of the Royal Society B researchers of the Netherlands Institute of Ecology (NIOO-KNAW) launch a new approach to these 'extreme' studies.

Study solves mystery of how plants use sunlight to tell time via cell protein signaling

Findings of a new study solve a key mystery about the chemistry of how plants tell time so they can flower and metabolize nutrients.

NASA Aims to Create First-Ever Space-Based Sodium Lidar to Study Poorly Understood Mesosphere

A team of NASA scientists and engineers now believes it can leverage recent advances in a greenhouse-detecting instrument to build the world’s first space-based sodium lidar to study Earth’s poorly understood mesosphere.

Scientist Diego Janches and laser experts Mike Krainak and Tony Yu, all of whom work at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are leading a research-and-development effort to further advance the sodium lidar, which the group plans to deploy on the International Space Station if it succeeds in proving its flightworthiness.

NASA’s Center Innovation Fund and the Heliophysics Technology and Instrument Development for Science programs are now funding the instrument’s maturation. However, the concept traces its heritage in part to NASA’s past investments in promising lidar instruments, called Sounders, originally created to measure carbon dioxide and methane in Earth’s atmosphere.
