Multiple Personalities: It's Not a Disorder Anymore - 0 views

  •  
    I hope you've had a chance to watch Ray Kurzweil's presentation on yesterday's post. My interest was piqued by several things he mentioned. (I wish I could think about them all at the same time, but possessing that kind of capability will have to wait for some heavy duty augmentation.) One thing in particular got a good grasp on my attention. Ray spent about 2 seconds on the idea that technological advances in virtual reality and artificial intelligence will allow me to create several virtual personalities to perform the routine transactions made necessary by modern life.

Grassroots Nanotech: Controlled Self-Assembly - 0 views

  •  
    Throughout our history, mankind has created tools the same way, essentially using the top-down approach. Think about it. In the stone age, a sharp cutting tool was fashioned by using a larger stone to chip away pieces until the cutting stone was sharp enough. Today, a computer chip is made by a large laser that etches the circuits into a piece of silicon.

Going All-Virtual: The Desire to Leave Reality Behind - 0 views

  •  
    Considering the implications of the singularity is a fascinating exercise. We will be facing choices and available enhancements that require of us quite a bit of imagination if we are to even tentatively understand them. In this article I will raise an issue that I think will confront society at large and ourselves as individuals within the next few decades: Should I go virtual and leave reality behind?

Will Humans Become Attached to Robots? - 0 views

    Will Humans Become Attached to Robots?Many have speculated about how humanity will react to robots. There are researchers who are focused entirely on making robots look more like humans, adding facial expressiveness, gestures and head movements like nods and shakes, all designed to help us accept robots into our lives. But I don't think that's going to be a problem.

Belief In Climate Change Hinges On Worldview : NPR - 0 views

  • "People tend to conform their factual beliefs to ones that are consistent with their cultural outlook, their world view," Braman says. The Cultural Cognition Project has conducted several experiments to back that up. Participants in these experiments are asked to describe their cultural beliefs. Some embrace new technology, authority and free enterprise. They are labeled the "individualistic" group. Others are suspicious of authority or of commerce and industry. Braman calls them "communitarians." In one experiment, Braman queried these subjects about something unfamiliar to them: nanotechnology — new research into tiny, molecule-sized objects that could lead to novel products. "These two groups start to polarize as soon as you start to describe some of the potential benefits and harms," Braman says. The individualists tended to like nanotechnology. The communitarians generally viewed it as dangerous. Both groups made their decisions based on the same information. "It doesn't matter whether you show them negative or positive information, they reject the information that is contrary to what they would like to believe, and they glom onto the positive information," Braman says.
  • "Basically the reason that people react in a close-minded way to information is that the implications of it threaten their values," says Dan Kahan, a law professor at Yale University and a member of The Cultural Cognition Project. Kahan says people test new information against their preexisting view of how the world should work. "If the implication, the outcome, can affirm your values, you think about it in a much more open-minded way," he says. And if the information doesn't, you tend to reject it. In another experiment, people read a United Nations study about the dangers of global warming. Then the researchers told the participants that the solution to global warming is to regulate industrial pollution. Many in the individualistic group then rejected the climate science. But when more nuclear power was offered as the solution, says Braman, "they said, you know, it turns out global warming is a serious problem."And for the communitarians, climate danger seemed less serious if the only solution was more nuclear power.

  • Then there's the "messenger" effect. In an experiment dealing with the dangers versus benefits of a vaccine, the scientific information came from several people. They ranged from a rumpled and bearded expert to a crisply business-like one. The participants tended to believe the message that came from the person they considered to be more like them. In relation to the climate change debate, this suggests that some people may not listen to those whom they view as hard-core environmentalists. "If you have people who are skeptical of the data on climate change," Braman says, "you can bet that Al Gore is not going to convince them at this point." So, should climate scientists hire, say, Newt Gingrich as their spokesman? Kahan says no. "The goal can't be to create a kind of psychological house of mirrors so that people end up seeing exactly what you want," he argues. "The goal has to be to create an environment that allows them to be open-minded."And Kahan says you can't do that just by publishing more scientific data.

    "It's a hoax," said coal company CEO Don Blankenship, "because clearly anyone that says that they know what the temperature of the Earth is going to be in 2020 or 2030 needs to be put in an asylum because they don't." On the other side of the debate was environmentalist Robert Kennedy, Jr. "Ninety-eight percent of the research climatologists in the world say that global warming is real, that its impacts are going to be catastrophic," he argued. "There are 2 percent who disagree with that. I have a choice of believing the 98 percent or the 2 percent." To social scientist and lawyer Don Braman, it's not surprising that two people can disagree so strongly over science. Braman is on the faculty at George Washington University and part of The Cultural Cognition Project, a group of scholars who study how cultural values shape public perceptions and policy

Acupuncture lessens depression symptoms during pregnancy, study shows - 0 views

  • The study authors, led by Rachel Manber, PhD, professor of psychiatry and behavioral sciences, said they hope the results will raise awareness of the problem of depression during pregnancy and provide patients and physicians an alternative to antidepressants. "This standardized acupuncture protocol could be a viable treatment option for depression during pregnancy," they wrote in a paper that will appear in the March issue of Obstetrics & Gynecology. Up to 14 percent of pregnant women may have major depressive disorder, a condition characterized by feelings of dread, gloom and hopelessness, and a loss of interest in normally pleasurable activities. Some women suffer from depression before becoming pregnant, stop taking their medication and then experience a relapse; in other women, pregnancy itself may cause depression.
  • For this study, the researchers recruited 150 women whose pregnancies were between 12 and 30 weeks gestation and who met the criteria for major depressive disorder. The women were randomized to receive one of three treatments: acupuncture specific for depression; control acupuncture, during which needles were inserted in points not known to help alleviate depressive symptoms; or massage. All of the women received eight weeks of therapy and were assessed for depression at the four- and eight-week marks by an interviewer who was unaware of the treatment each woman received. The researchers found that women who received the depression-specific acupuncture experienced a bigger reduction in depression symptoms than the women in the other groups. The response rate — defined as having a 50 percent or greater reduction in symptoms — was 63 percent for the women receiving depression-specific acupuncture, compared with 44 percent for the women in the other two treatment groups combined. The researchers weren't surprised by what they found — a pilot study yielded similar results, and other studies have shown acupuncture is an effective treatment for depression in the general public — but they were pleased with the results. "I don't think that one-size-fits-all treatments are appropriate for everyone, but acupuncture should be considered as an option," said Lyell. "I hope that people will respect the rigorous methodology used in this blinded, randomized, controlled trial and accept the result: Traditional acupuncture was associated with a significant improvement in depression."

Research: How you think about your age may affect how you age - 0 views

  • "How old you are matters, but beyond that it's your interpretation that has far-reaching implications for the process of aging," said Markus H. Schafer, a doctoral student in sociology and gerontology who led the study. "So, if you feel old beyond your own chronological years you are probably going to experience a lot of the downsides that we associate with aging. "But if you are older and maintain a sense of being younger, then that gives you an edge in maintaining a lot of the abilities you prize." Schafer and co-author Tetyana P. Shippee, a Purdue graduate who is a research associate at Purdue's Center on Aging and the Life Course, compared people's chronological age and their subjective age to determine which one has a greater influence on cognitive abilities during older adulthood. Nearly 500 people ages 55-74 were surveyed about aging in 1995 and 2005 as part of the National Survey of Midlife Development in the United States. In 1995, when people were asked what age do you feel most of the time, the majority identified with being 12 years younger than they actually were. "We found that these people who felt young for their age were more likely to have greater confidence about their cognitive abilities a decade later," Schafer said. "Yes, chronological age was important, but the subjective age had a stronger effect. "What we are not sure about is what comes first. Does a person's wellness and happiness affect their cognitive abilities or does a person's cognitive ability contribute to their sense of wellness. We are planning to address this in a future study."

'Hella' Proposed as Official Big Number - Yahoo! News - 0 views

  • To become official, "hella" would have to jump through quite a few bureaucratic hoops. It would have to pass through the Consultative Committee for Units (CCU), one of 10 advisory committees of the International Committee for Weights and Measures (CIPM). If the CCU recommends it the CIPM, that board must then decide whether to advance the cause to the General Conference on Weights and Measures (CGPM), the official authority that can make changes to the SI system. That international organization, based in France, includes members from 81 countries. "I think that for a number of reasons it's a long shot," said Ben Stein, a spokesperson for the National Institute of Standards and Technology, the U.S. organization that handles measurements. "The types of things they would consider are is it needed, does it add or reduce confusion, are the names consistent with other names associated with the prefixes?" Sendek argues that the name would honor the scientific contributions of Northern Californians, who have famously popularized the phrase "hella" to mean "a whole lot."
  •  
    Soon the word "hella" may not be associated with California surfers as much as with scientists in lab coats. A physics student is petitioning to add "hella" to the International System of Units (SI) as the official designation of 10 to the 27th power, or a trillion trillions.

Exotic Antimatter Created on Earth - Yahoo! News - 0 views

  • Among the many particles that resulted from this crash were bizarre objects called anti-hypertritons. Not only are these things antimatter, but they're also what's called strange matter. Where normal atomic nuclei are made of protons and neutrons (which are made of "up" quarks and "down" quarks), strange nuclei also have so-called Lambda particles that contain another flavor of quark called "strange" as well. These Lambda particles orbit around the protons and neutrons. If all that is a little much to straighten out, just think of anti-hypertritons as several kinds of weird. Though they normally don't exist on Earth, these particles may be hiding in the universe in very hot, dense places like the centers of some stars, and most likely were around when the universe was extremely young and energetic, and all the matter was packed into a very small, sweltering space. "This is the first time they've ever been created in a laboratory or a situation where they can be studied," said researcher Carl Gagliardi of Texas A&M University. "We don't have anti-nuclei sitting around on a shelf that we can use to put anti-strangeness into. Only a few anti-nuclei have been observed so far." These particles weren't around for too long, though – in fact, they didn't last long enough to collide with normal matter and annihilate. Instead they just decayed after a fraction of a billionth of a second. "That sounds like a really short time, but in fact on the nuclear clock it's actually a long time," Gagliardi told SPACE.com. "In that fraction of a billionth of a second that Lambda particle has already gone around the nucleus as many times as the Earth has gone around the sun since the solar system was created."

    Scientists have created a never-before seen type of exotic matter that is thought to have been present at the earliest stages of the universe, right after the Big Bang. The new matter is a particularly weird form of antimatter, which is like a mirror-image of regular matter. Every normal particle is thought to have an antimatter partner, and if the two come into contact, they annihilate. The recent feat of matter-tinkering was accomplished by smashing charged gold atoms at each other at super-high speeds in a particle accelerator called the Relativistic Heavy Ion Collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory in Upton, N.Y.
