Oceans become more acidic as they absorb excess carbon dioxide, and for reasons still not entirely understood, sound goes farther in acidic water. "The waters in the upper ocean are now undergoing an extraordinary transition in their fundamental chemical state at a rate not seen on Earth for millions of years," wrote scientists from the Monterey Bay Aquarium Research Institute in a study published in Geophysical Research Letters. "The effects are being felt not only in biological impacts, but also on basic geophysical properties including ocean acoustics." By 2050, they say, sound will travel up to 70 percent farther through the seas than it does now. The effect will be most pronounced at frequencies used by marine mammals. What this means for the animals isn't entirely clear, but research suggests that sounds from ship engines and propellers already interfere with whale and dolphin communication -- and other species have yet to be studied. "While nobody knows the precise consequences for specific animals," said International Fund for Animal Welfare director Robbie Marsland in a recent BBC article, "we are likely to discover only too late the terrible damage we're causing."

In the welcoming ceremony video you can see the crew preparing for the cameras by smoothing out their hair, passing out snaking coils of headset cords, and floating over the rest of the group to get in position. A Russian space official starts off the ceremony by joking that he could see the departing space station crew are all "due for a haircut." You also get to hear NASA astronaut Mike Fincke thanking his three young daughters for letting him go to space for six months and signing off, "I love you — from space!" Garriott reportedly paid $30 million for the 10-day mission on the Space Station under a deal between Russia's Federal Space Agency (Roscosmos) and the Virginia-based firm Space Adventures and is their sixth orbital spaceflight customer. Garriott is adding fun, artistic, educational, scientific and commercial objectives to his mission, including carrying some of Stephen Colbert's DNA for a project called "Operation Immortality." All the mayhem can be tracked on his website www.richardinspace.com. During the launch Sunday from Kazakhstan, Garriott held up a sign with a message written in the language of the Tabula Rasa game for fans to decode. He also plans to participate in a number of educational activities sponsored by the Challenger Learning Centers, a group whose founding chairman is June Scobee Rodgers, the widow of a Space Shuttle Challenger commander. Rodgers was one of Garriott's teachers when he was growing up in Nassau Bay, Texas as the son of astronaut Owen Garriott. Garriott's parents and his brother were on hand to razz him during the ceremony as well. His mom called him Peter Pan because he could now fly, something they got to do together on the Zero-G plane this past Easter. Garriot smiled through it all and assured them that he was, "sure enjoying it so far."
Both of their space-faring fathers were on hand in Russian Mission Control to congratulate them at the welcome ceremony. Owen Garriott spend two months in space during the Skylab 3 missions in 1973 and Alexander Volkov flew on Soyuz TM-13 in 1991, launching as a Soviet citizen and returning as a Russian citizen. The two sons are to return to Earth together in a Soyuz vehicle in about ten days time. The previous two Soyuz re-entries have been ballistic, high-g, off-nominal re-entries due an explosive bolt failing to fire. Cosmonauts did a daring spacewalk earlier this summer to try to fix the problem by removing the offending bolt. See Also:

Also known as worm snorers and worm fiddlers, they catch earthworms for fish bait by plunging a wooden stake into the ground and rubbing it with steel. The resulting sound drives worms aboveground, though the scientists didn't know why — until now. All this fiddling, snoring and grunting, found Vanderbilt University biologist Ken Catania, amounts to one thing: the sound made by burrowing, worm-hungry moles. Darwin himself suspected as much. "It is often said that if the ground is beaten or otherwise made to tremble worms will believe that they are pursued by a mole and leave their burrows," he wrote in The Formation of Vegetable Mould through the Action of Worms, a book that is largely forgotten but reflects his enduring and instructive fascination with a creature that most people, then as now, ignore. To test Darwin's supposition, Catania enlisted the services of veteran worm grunters Gary and Audrey Revell, among the last of what was once a rich worm grunting community in Florida's Apalachicola National Forest. Catania observed what the Revells already knew: grunting indeed brings worms to the surface. He then filled a box with worms, and allowed a captive mole to tunnel in from the side. The worms responded by surfacing. Some people have suggested that worm grunting mimics the sound of falling rain, but worms in a sprinkler-doused test box failed to rise. And according to Catalonia's geophone measurements, worm grunting and mole burrowing produce comparable sounds.
Darwin's worm research began shortly after his historic voyage on the Beagle, culminating four decades later with the 1881 publication of Action of Worms; he showed, among other things, that earthworms do not respond to the notes of a whistle, a piano or a bassoon, and are "indifferent to shouts." He also realized that England's lush topsoil was the product of ceaseless soil consumption and defecation by earthworms: about 54,000 per acre, depositing ten tons of fresh soil atop each acre of English countryside, every single year. "It may be doubted whether there are any other animals which have played so important a part in the history of the world as have these lowly, organized creatures," Darwin wrote. This now-forgotten fascination was chronicled by David Quammen in an essay entitled "Thinking About Earthworms." To Quammen, Darwin didn't merely illuminate the importance of these underestimated invertebrates, but the importance of thinking individually. "At the time, evolution by natural selection was the hottest idea in science; yet Charles Darwin spent his last year of work thinking about earthworms. And thank goodness he did," wrote Quammen. "More and more in recent years, we are all thinking about the same things at the same time.... Break stride. Wander off mentally. Pick a subject so perversely obscure that it can't help but have neglected significance." That is, after all, what Darwin did. What about you?

The finding could transform both popular and scientific understanding of bonobos, which like chimpanzees share 98 percent of their DNA with humans. But unlike chimps, bonobos have been considered gentle and good-natured: they don't engage in inter-tribal warfare or primate cannibalism, are dominated by females rather than males, and exchange sexual acts with the casualness of humans talking about the weather. Such easygoing promiscuity has earned bonobos a unique place in the popular imagination — "equal parts dolphin, Dalai Lama, and Warren Beatty," in the words of New Yorker writer Ian Parker. But the reputation is based on limited evidence: most observations come from a couple hundred captive bonobos, and only a few primatologists track our endangered cousin in its remote Congolese home. One such primatologist is Gottfried Hohmann of the Max Planck Institute for Evolutionary Anthropology, a central figure in Parker's article and author of a study, published yesterday in Current Biology, that describes bands of bonobos tracking, killing and eating young monkeys. This may be shocking news to bonobo-idealizing humans, but less so to scientists, who have inferred the primate-cannibalizing capacity of bonobos from the presence of monkey fingers in their droppings. For them, the findings provide an opportunity to reconfigure their understanding of a species separated from humans by a mere four million years. "Now that actual observations have been made, the issue is much clearer, and it changes our perception of bonobo social organization and socio-ecology," said Frans de Waal, a Yerkes National Primate Research Center psychologist who has studied captive bonobos. He called Hohmann's findings a "great discovery," comparing them to field observations of chimpanzees several decades ago, when great variations between chimpanzee populations were first reported. The findings' most profound implications may involve the nature of sex and violence. "In chimpanzees, male-dominance is associated with physical violence, hunting and meat consumption," said Hohmann in a press release. "By inference, the lack of male dominance and physical violence is often used to explain the relative absence of hunting and meat eating in bonobos." Even a female-dominated hominid species, it seems, is capable of behavior that would disqualify them from the sort of plaudits served by New York Times science writer Natalie Angier, for whom the bonobo "stands out from the chest-thumping masses as an example of amicability, sensitivity and, well, humaneness." But much remains to be learned. It is not clear, wrote Hohmann, whether primates are a bonobo dietary staple or last resort, or whether his group is unique in its taste and tactics. In other instances, bonobos have been observed socializing, and even engaging in mutual grooming, with the same monkey species that Hohmann's band killed. "We cannot exclude the possibility that inter-site variation in hunting behavior, like inter-site variation in tool use and other behaviors of both Pan species, reflects variation in local, socially transmitted traditions," wrote Hohmann. Like Jack's tribe in Lord of the Flies, Hohmann's bonobos may have gone rogue — a possibility that will no doubt appeal to some bonobo lovers. And to them, de Waal extends more solace: predation, he said, is not the same as aggression, and eating another species is very different from eating your own, as chimpanzees are wont to do. "This finding does very little to change the idea of bonobos as relatively peaceful primates," said de Waal.

Source: Wired: Wired Science | 14 Oct 2008 | 6:33 pm Videos Simulate Earthquake in San Francisco Bay Area
When asked where the next big Bay Area quake is likely to be, most geologists will bet on the Hayward Fault, which runs along the eastern side of the bay through a densely populated area that includes Oakland, Berkeley and Hayward. The last major quake on that fault struck 140 years ago in 1868, and the average time between big ones is 140 years. "The next large earthquake could occur at any time," said geologist Brad Aagard of the USGS at a press conference today. "We expect it to be between a magnitude 6.8 and 7.2." Aagard created several video simulations of Bay Area earthquakes, including the one directly above of a magnitude 7.0 earthquake on the Hayward fault. The ground motion is exaggerated by 1,000 to help with the visualization. The red color indicates very violent shaking that can cause significant damage. Seismologist Mary Lou Zoback of Risk Management Solutions in Hayward estimates a magnitude 7.0 earthquake on Hayward fault quake could result in $200 billion in damage from shaking, thousands of deaths and hundreds of thousands of displaced people. Zoback likens the quake aftermath to that of Hurricane Katrina, which caused a similar amount of damage. The difference is that only 7 or 8 percent of the Bay Area's losses will be covered, far less than the $56 billion that flowed into Louisiana from insurance companies after Katrina. "We'll have a comparable size loss and only about $8 billion in insurance payments." Image: Damage in San Francisco after the 1868 Hayward Fault earthquake; Bancroft Library, UC Berkeley.
