By manipulating the timing of disease-causing mutations in the brains of developing mice, Brown University researchers have found that early genetic deletions in the thalamus may play an important role in course and severity of the developmental disease tuberous sclerosis complex. Findings appear in the journal Neuron.

PROVIDENCE, R.I. [Brown University] — Doctors often diagnose tuberous sclerosis complex (TSC) based on the abnormal growths the genetic disease causes in organs around the body. Those overt anatomical structures, however, belie the microscopic and mysterious neurological differences behind the disease’s troublesome behavioral symptoms: autism, intellectual disabilities, and seizures. In a new study in mice, Brown University researchers highlight a role for a brain region called the thalamus and show that the timing of gene mutation during thalamus development makes a huge difference in the severity of the disease.

Using earthquake sensors to track endangered whales

The fin whale is the second-largest animal ever to live on Earth. It is also, paradoxically, one of the least understood. The animal’s huge size and global range make its movements and behavior hard to study.

A carcass that washed up on a Seattle-area beach this spring provided a reminder that sleek fin whales, nicknamed “greyhounds of the sea,” are vulnerable to collision when they strike fast-moving ships. Knowing their swimming behaviors could help vessels avoid the animals. Understanding where and what they eat could also help support the fin whale’s slowly rebounding populations. (more…)

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…)

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

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…)
