Maintaining a Satellite Link: GTRI Agile Aperture Antenna Technology is Tested on an Autonomous Ocean Vehicle

Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.

The Agile Aperture Antenna technology developed by the Georgia Tech Research Institute (GTRI) is expected to provide a more reliable and faster method of transmitting video, audio and environmental data – such as salinity, temperature, fluorescence and dissolved oxygen – from an ocean vehicle to land via satellite.

NASA telescope provides insights into unusual dwarf star

Astronomer John Gizis of the University of Delaware, working with data obtained by NASA’s Kepler telescope, is studying a highly unusual dwarf star and its powerful flares that may hold clues to the likelihood of life on other planets as well as to the behavior of our sun.

Gizis, associate professor in the Department of Physics and Astronomy, discovered the star two years ago using a ground-based telescope and now has conducted additional research using Kepler observations over the past two years. (more…)

Oscar winner Randy Thom discusses sound design in first film of new series

Technology

Microsoft’s new film series “On the Whiteboard” explores topics at the intersection of technology and culture, and introduces people, places and things behind the products.

REDMOND, WASH. – June 17, 2013 – In the first episode of Microsoft’s new film series “On the Whiteboard,” Editor Pamela Woon chats with two-time Oscar winner Randy Thom about the (often underestimated) importance of sound in human-technology interactions.

Thom, the lead sound designer at Skywalker Ranch who worked on films such as The Incredibles, Castaway and Forrest Gump, says that people rarely consider the significance of those signature sounds that come from their trusty devices, whether it be a cell phone, a computer or a tablet. (more…)

Black Hole Naps amidst Stellar Chaos

Science

Nearly a decade ago, NASA’s Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep.

“Our results imply that the black hole went dormant in the past 10 years,” said Bret Lehmer of the Johns Hopkins University, Baltimore, and NASA’s Goddard Space Flight Center, Greenbelt, Md. “Periodic observations with both Chandra and NuSTAR should tell us unambiguously if the black hole wakes up again. If this happens in the next few years, we hope to be watching.” Lehmer is lead author of a new study detailing the findings in the Astrophysical Journal. (more…)

Vegetable Oil Is Good for You, MU Researcher Says

Health

Scientists find that essential fatty acid found in vegetable oils does not promote inflammation in humans

COLUMBIA, Mo. — A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim.

In the study, “Effect of Dietary Linoleic Acid on Markers of Inflammation in Healthy Persons: A Systematic Review of Randomized Controlled Trials,” researchers at the University of Missouri and the University of Illinois found that no link exists between vegetable oil consumption and circulating indicators of inflammation that are often associated with diseases such as heart disease, cancer, asthma and arthritis. While earlier animal studies have shown that a diet rich in LA can promote inflammation, MU animal sciences researcher Kevin Fritsche says that humans respond to LA differently. (more…)
