			<content:encoded><![CDATA[<p>BOSTON &#8211; Scientists and the public agree that the promise of nanotechnology is great, but there are risks to it and they should be governed accordingly.</p>
<p>The new technology, which is making its way into products ranging from food storage containers to computers, is seen differently among scientists than the general public, with scientists appearing to be more concerned in some areas. But in broad categories of risk versus reward both groups seem to agree &#8211; go slow and be cautious of the technology&#8217;s deleterious effects. What may be most useful in the future are good, trusted communicators.</p>
<p>These are among the findings of a recent survey that will be presented by Elizabeth Corley, an Arizona State University assistant professor in the School of Public Affairs, on Feb. 15 at the American Association for the Advancement of Science annual meeting.</p>
<p>The report is based on a national telephone survey of American households and a sampling of 363 leading U.S. nanotechnology scientists and engineers. It reveals that scientists who have the most insight into a technology with enormous potential &#8212; and that is already emerging in hundreds of products &#8212; are unsure what health and environmental problems might be posed by the technology.</p>
<p>Findings of the report, first published in the journal Nature Nanotechnology (Nov. 25, 2007), were in stark contrast to controversies sparked by the advent of major past technologies, such as nuclear power and genetically modified foods, which scientists perceived as having lower risks than did the public.</p>
<p>Nanotechnology is based on science&#8217;s newfound ability to manipulate matter at the smallest scale, on the order of molecules and atoms. The field has enormous potential to develop applications ranging from new antimicrobial materials and tiny probes to sample individual cells in human patients, to vastly more powerful computers and lasers. Already, products with nanotechnology built in include golf clubs, tennis rackets and antimicrobial food storage containers.</p>
<p>At the root of the information disconnect, said Corley, who conducted the survey with Dietram Scheufele of the University of Wisconsin-Madison, is that nanotechnology is only now starting to emerge on the nation&#8217;s policy agenda. Amplifying the problem is that the news media have not paid much attention to nanotechnology and its implications.</p>
<p>&#8220;In the long run, this information disconnect could undermine public support for federal funding in certain areas of nanotechnology research, particularly in those areas that the public views as having lower levels of risk,&#8221; Corley said.</p>
<p>While scientists were generally optimistic about the potential benefits of nanotechnology, they expressed significantly more concern about pollution and new health problems related to the technology. Twenty percent of the scientists responding to the survey indicated a concern that new forms of nanotechnology pollution may emerge, while only 15 percent of the public thought that might be a problem. More than 30 percent of scientists expressed concern that human health may be at risk from the technology, while just 20 percent of the public held such fears.</p>
<p>Of more concern to the American public, according to the report, are a potential loss of privacy from tiny new surveillance devices and the loss of more U.S jobs. Those fears were less of a concern for scientists.</p>
<p>While divergent in some specific views, Corley said that scientists and the public seem to agree in broad terms on the rewards versus the risks of nanotech.</p>
<p>&#8220;Not surprisingly, scientists are more likely than the public to find nanotechnology research useful and morally acceptable,&#8221; Corley said. &#8220;Yet, scientists and the public have similar perceptions (around 17 percent) of the overall risks of nanotechnology and the need for government regulations of nanotechnology (around 40 percent).</p>
<p>&#8220;Our new analysis shows that despite scientists&#8217; perceptions of high levels of benefit from nanotechnology research, they tend to agree with the public that they should pay attention to government regulations and unknown risks,&#8221; she explained.</p>
<p>Corley added that the survey shows university scientists are the ones thought to be most qualified to communicate the potential risks and benefits of the technology. Some 88 percent of scientists believe university scientists have the necessary expertise, while about 75 percent think that nanotech industry scientists have the required level of expertise. Yet the public is less likely to trust nanotech industry scientists. Of the three groups that the public trusts most &#8212; university scientists, consumer organizations and regulators &#8211; the only group that more than half the public trusts are university scientists.</p>
<p>&#8220;This is a policy relevant finding,&#8221; she added, &#8220;because, on average, university nanotech scientists have been hesitant to engage the public in this sort of discourse.&#8221;</p>

			<content:encoded><![CDATA[<p><font face="Times New Roman">Sun worshippers beware. While using sunscreen to block dangerous UV rays, you may be exposing yourself to a new danger.  Sunscreen manufacturers are adding nanoparticles to sunscreens to make sun-blocking ingredients like titanium dioxide and zinc oxide rub on clear instead of white. These nanoparticles are being added without appropriate labeling or reliable safety information-and they pose potential threats to human health.</p>
<p>Friends of the Earth asked more than 120 sunscreen manufacturers to describe their companies&#8217; policies regarding nanotechnology and whether their products contain nanoparticles, but the vast majority of manufacturers refused.  This underscores the challenge that consumers face when trying to determine if their sunscreens are safe, which is why FDA regulation and labeling requirements are urgently needed.</p>
<p>In the meantime, Friends of the Earth has compiled a guide to alert consumers to the risks that may come from sunscreens with nanoparticles and a list of nine sunscreen brands that are nano free.  To learn more about nanomaterials in sunscreens, and how to limit your risk of exposure, visit <a target="_blank" href="http://www.foe.org/nano_sunscreens_guide/Nano_Sunscreens.pdf"><strong>our guide</strong></a>.</p>
<p><strong>Links:</strong></p>
<p>Click <a href="http://www.foe.org/nano_sunscreens_guide/Nano_Sunscreens.pdf"><strong>here</strong></a> for the <strong>full text of the report</strong> with more information about the damage nanoparticles could cause. For more information on the findings of the report, please contact Health and Environment Campaigner Ian Illuminato at <a href="mailto:iilluminato@foe.org"><strong>iilluminato@foe.org</strong></a> or 202-783-7400.</p>
<p>Also, you can click <a href="http://www.foe.org/nano_sunscreens_guide/Nano_Sunscreen_Guide.pdf"><strong>here</strong></a> for a <strong>standalone list</strong> of the sunscreens that do, don&#8217;t or may contain nanoparticles.</p>
<p>You can also listen to an <strong>audio recording</strong> of Illuminato and Friends of the Earth President Brent Blackwelder discussing the consumer guide.  Blackwelder speaks first, Illuminato second.  The recording is available <a href="http://www.foe.org/nano_sunscreens_guide/Nano_Sunscreens_Audio.wav"><strong>here</strong></a>.</p>
<p>We asked 128 cosmetics companies whether they were using nanotechnology, which is largely untested and may pose real dangers to human health, in making their skin products. See a <strong>copy of the letter we sent</strong> them <a href="http://www.foe.org/nano_sunscreens_guide/Sample_Company_Correspondences/Sample_of_1st_correspondence.pdf"><strong>here</strong></a>, and our follow-up letters <a href="http://www.foe.org/nano_sunscreens_guide/Sample_Company_Correspondences/Sample_of_2nd_correspondence.pdf"><strong>here</strong></a> and <a href="http://www.foe.org/nano_sunscreens_guide/Sample_Company_Correspondences/Sample_of_3rd_correspondence.pdf"><strong>here</strong></a>.</p>

			<content:encoded><![CDATA[<p>A new study of worldwide technological competitiveness suggests China may soon rival the United States as the principal driver of the world’s economy — a position the U.S. has held since the end of World War II. If that happens, it will mark the first time in nearly a century that two nations have competed for leadership as equals.</p>
<p>The study’s indicators predict that China will soon pass the United States in the critical ability to develop basic science and technology, turn those developments into products and services — and then market them to the world. Though China is often seen as just a low-cost producer of manufactured goods, the new “High Tech Indicators” study done by researchers at the Georgia Institute of Technology clearly shows that the Asian powerhouse has much bigger aspirations.</p>
<p>“For the first time in nearly a century, we see leadership in basic research and the economic ability to pursue the benefits of that research — to create and market products based on research — in more than one place on the planet,” said Nils Newman, co-author of the National Science Foundation-supported study. “Since World War II, the United States has been the main driver of the global economy. Now we have a situation in which technology products are going to be appearing in the marketplace that were not developed or commercialized here. We won’t have had any involvement with them and may not even know they are coming.”</p>
