Optical System Promises To Revolutionize Undersea Communications

An artist's conception of how the optical modem could function at a deep ocean cabled observatory. Autonomous underwater vehicles (AUVs) collect sonar images (downward bands of light) and other data at a hydrothermal vent site and transmit the data through an optical modem to receivers stationed on moorings in the ocean. The moorings are connected to a cabled observatory, and the data are sent back to scientists on shore. Scientists, in turn, can send new instructions to the AUVs via the optical modem as well.

Giant Iceberg Could Change Weather Patterns

From The Australian/AFP:

AN iceberg the size of Luxembourg knocked loose from the Antarctic continent earlier this month could disrupt the ocean currents driving weather patterns around the globe, researchers said.

While the impact would not be felt for decades or longer, a slowdown in the production of colder, dense water could result in less temperate winters in the north Atlantic, they said.

The 2550 sq km block broke off on February 12 or 13 from the Mertz Glacier Tongue, a 160km spit of floating ice protruding into the Southern Ocean from East Antarctica due south of Melbourne, researchers said.

Some 400m thick, the iceberg could fill Sydney Harbour more than 100 times over.

Killer Whales Don't Usually Kill People

From Live Science:

News of a trainer being killed by a killer whale at SeaWorld Orlando today doesn't change the fact that these giants, while deadly predators, do not kill humans at sea.

"They have never killed a human in the wild," said Nancy Black, a marine biologist with Monterey Bay Whale Watch. That's mostly because, unlike sharks, killer whales don't frequent near-shore areas where people swim. (Even shark attacks on humans are generally accidental, experts say, with sharks mistaking humans for seals or other typical food.)

Under Fire, Administrator Defends NASA’s New Direction

From The New York Times:

WASHINGTON — Maj. Gen. Charles F. Bolden Jr., the administrator of the National Aeronautics and Space Administration, faced skeptical, sometimes hostile questioning on Thursday from members of a key House committee who said they opposed the Obama administration’s plans to revamp the nation’s human spaceflight program.

General Bolden told the Committee on Science and Technology that the president’s $19 billion budget proposal for NASA — which would cancel the agency’s program to send astronauts back to the Moon, invest in new space technologies and turn to commercial companies for transportation beyond low-Earth orbit — would provide a “more affordable and more sustainable” approach to space exploration.

Physicists Discover Odd Fluctuating Magnetic Waves

Brown University physicist Vesna Mitrovic and colleagues have discovered magnetic waves that fluctuate when exposed to certain conditions in a superconducting material. The find may help scientists understand more fully the relationship between magnetism and superconductivity. (Credit: Lauren Brennan/Brown University)

From Science Daily:

Science Daily (Feb. 24, 2010) — At the quantum level, the forces of magnetism and superconductivity exist in an uneasy relationship. Superconducting materials repel a magnetic field, so to create a superconducting current, the magnetic forces must be strong enough to overcome the natural repulsion and penetrate the body of the superconductor. But there's a limit: Apply too much magnetic force, and the superconductor's capability is destroyed.

Brain 'Hears' Sound Of Silence

Although more research needs to be done, the work carried out by Wehr and his team could lead to new treatments for impaired hearing. Getty Images

From Discovery News:

While we think of silence as the absence of sound, the brain detects it nonetheless.

THE GIST:

* The brain responds not only to sound but also to silence, according to a new study.
* Different pathways in the brain respond to the onset and the offset of sounds.
* Better knowing how the brain organizes and groups sounds could lead to more effective hearing therapies and devices.

While we characterize silence as the absence of sound, the brain hears it as loud and clear as any other noise.

In fact, according to a recent study from the University of Oregon, some areas of the brain respond solely to sound termination. Rather than sound stimuli traveling through the same brain pathways from start to finish as previously thought, neuron activity in rats has shown that onset and offset of sounds take separate routes.
