Study reveals vision’s role in vowel perception

In a study based at Brown University, researchers found that the motion and configuration of a speaker’s lips are key components of the information people gather when distinguishing vowels in speech.

PROVIDENCE, R.I. [Brown University] — For all talkers, except perhaps the very best ventriloquists, the production of speech is accompanied by visible facial movements. Because speech is more than just sound, researchers set out to ascertain the exact visual information people seek when distinguishing vowel sounds. (more…)

Hacking a pressure sensor to track gradual motion along marine faults

By Guest PostDecember 24, 2017Sciencecascadia subduction zone, dana manalang, earthquakes, jerry paros, marine faults, motion, pressure sensor, tsunamis, william wilcock

Deep below the ocean’s surface, shielded from satellite signals, the gradual movement of the seafloor — including along faults that can unleash deadly earthquakes and tsunamis — goes largely undetected. As a result, we know distressingly little about motion along the fault that lies just off the Pacific Northwest coast. (more…)

Berkeley Lab Researchers Make a Powerful New Microscale Torsional Muscle/Motor from Vanadium Dioxide

Vanadium dioxide is poised to join the pantheon of superstars in the materials world. Already prized for its extraordinary ability to change size, shape and physical identity, vanadium dioxide can now add muscle power to its attributes. A team of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has demonstrated a micro-sized robotic torsional muscle/motor made from vanadium dioxide that for its size is a thousand times more powerful than a human muscle, able to catapult objects 50 times heavier than itself over a distance five times its length within 60 milliseconds – faster than the blink of an eye.

Testing Einstein’s E=mc2 in Outer Space

UA physicist Andrei Lebed has stirred the physics community with an intriguing idea yet to be tested experimentally: The world’s most iconic equation, Albert Einstein’s E=mc2, may be correct or not depending on where you are in space.

With the first explosions of atomic bombs, the world became witness to one of the most important and consequential principles in physics: Energy and mass, fundamentally speaking, are the same thing and can, in fact, be converted into each other.

This was first demonstrated by Albert Einstein’s Theory of Special Relativity and famously expressed in his iconic equation, E=mc2, where E stands for energy, m for mass and c for the speed of light (squared). (more…)

Warmer waters flowed to shelfbreak south of New England

At a meeting with New England commercial fishermen last December, physical oceanographers Glen Gawarkiewicz and Al Plueddemann from the Woods Hole Oceanographic Institution (WHOI) were alerted by three fishermen about unusually high surface water temperatures and strong currents on the outer continental shelf south of New England.

“I promised them I would look into why that was happening,” Gawarkiewicz says. (more…)

Bounce, Skid, Wobble: How Huygens Landed on Titan

Piecing together the events of the farthest touchdown a manmade spacecraft has ever made on an alien world reveals new clues about Titan’s surface and helps plan future missions to moons and planets.

The Huygens probe, ferried to Saturn’s moon Titan by NASA’s Cassini spacecraft, bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Titan in January 2005, a new analysis reveals. The moon’s surface is more complex than previously thought.

Scientists reconstructed the chain of events by analyzing data from a variety of instruments that were active during the impact, in particular changes in the acceleration experienced by the probe. The probe was supplied by the European Space Agency and named after the Dutch 17th century astronomer Christiaan Huygens. (more…)

A Galactic Magnetic Field in A Lab Bolsters Astrophysical Theory

ANN ARBOR, Mich.— Why is the universe magnetized? It’s a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.

The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. (more…)
