Pinpoint Precision: Nanowires Deliver Biochemical Payloads to One Cell Among Many - 0 views

  •  
    "(PhysOrg.com) -- Imagine being able to drop a toothpick on the head of one particular person standing among 100,000 people in a stadium. It sounds impossible, yet this degree of precision at the cellular level has been demonstrated by researchers affiliated with the Johns Hopkins University Institute for NanoBioTechnology. Their study was published online in June in Nature Nanotechnology."

Watch Nanotechnology Take Off - 0 views

  •  
    I was a bit disappointed when I learned that the PBS documentary Nanotechnology Takes Off was not going to be aired in my neck of the woods back in March. OK, I was more than a bit disappointed. This was something I was deeply interested in, and I couldn't watch it. Well, it turns out I shouldn't have been so faithless, because it's now available for viewing online.

Carbon Nanotube Speakers Could Be Powered by Lasers, Transform Noisy Spaces into Peacef... - 6 views

  • “Nanotubes assemblies of various types are black and highly conductive,” said Dr. Mikhail Kozlov, a research scientist and the study’s lead author. “Their dark, conductive surface can be effectively heated with laser light or electricity to induce variations in the pressure of the air around the nanotubes — which we perceive as sound. It’s called the photo- or thermo-acoustic effect, and it’s the same principle Alexander Graham Bell used to produce sound on the first telephone.” With laser excitation, no electrical contact with the nanotube speaker is required, making the speakers wireless. “Speakers made with carbon nanotube sheets are extremely thin, light and almost transparent,” Kozlov said. “They have no moving parts and can be attached to any surface, which makes the surface acoustically active. They can be concealed in television and computer screens, apartment walls, or in the windows of buildings and cars. The almost invisible strands form films that can ‘talk.’” In addition to filling a room with sound from invisible speakers, nanotube speakers could easily cancel sound from the noisiest neighbor or dim the roar of traffic rushing past a neighborhood, using the same principles as current sound-canceling technologies. “The sound generation by nanotube sheets can help to achieve this effect on very large scales,” Kozlov said.

...You Might Be Wearing Nanotech - 0 views

  •  
    When it comes to nanotechnology, we've already pointed out that the public is blissfully unaware. I'm not sure why advertisers aren't making more of a fuss about it; perhaps they're wary of a negative reaction from consumers who may be a bit frightened by it. It's possible that people who would accept it, even welcome it, don't have as much money as the fraidy cats. But this is all speculation.

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

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.

Boiling the Frog: Our Transition to Singularity - 0 views

  •  
    You've all heard the metaphor, right? Boiling a frog? Gradually increasing the temperature of the water so the frog gets used to it until it's hot enough to boil? Yes, that one. Apart from the sad conclusion of the analogy, the idea of gradual change not being very noticeable fits the way that accelerating technological change will be accepted by humans.

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?

What Do Nanomachines Look Like? - 0 views

  •  
    When you hear about nanotechnology (and you will hear about it more and more since it's moving into the mainstream of manufacturing), you might wonder what a nanomachine might look like. Since you can't see them with your unaided eye, you have to look at highly magnified images. But for the folks whose job it is to design the tiny parts for the nanomachines, some powerful design software comes into play.
