  • Nanotubes found in lungs of French kids - Futurity
    everyone walking around out there in the world probably has at least a small concentration of carbon nanotubes in their lungs says Lon Wilson Credit Philippe Put Flickr Nanotubes found in lungs of French kids Rice University right Original Study Posted by Mike Williams Rice on October 19 2015 You are free to share this article under the Attribution 4 0 International license Cells taken from the airways of Parisian children with asthma contained man made carbon nanotubes just like the kind found in the exhaust pipes of vehicles in Paris The researchers report in the journal EBioMedicine that these samples align with what has been found elsewhere in US cities in spider webs in India and in ice cores The research in no way ascribes the children s conditions to the nanotubes says Rice University chemist Lon Wilson a corresponding author of a new paper describing the work But the nanotubes apparent ubiquity should be the focus of further investigation he adds We know that carbon nanoparticles are found in nature Wilson says noting that round fullerene molecules like those discovered at Rice are commonly produced by volcanoes forest fires and other combustion of carbon materials All you need is a little catalysis to make carbon nanotubes instead of fullerenes Carbon nanotubes the long rods and nanoparticles the black clumps appear in vehicle exhaust taken from the tailpipes of cars in Paris Courtesy of Fathi Moussa Paris Saclay University Carbon inside a lung cell vacuole takes the form of nanotubes rods and nanoparticles black clumps Courtesy of Fathi Moussa Paris Saclay University A car s catalytic converter which turns toxic carbon monoxide into safer emissions bears at least a passing resemblance to the high pressure carbon monoxide or HiPco process to make carbon nanotubes he says So it is not a big surprise when you think about it Wilson adds The team led by Wilson Fathi Moussa of Paris Saclay University and lead author Jelena Kolosnjaj Tabi a graduate student at Paris Saclay analyzed particulate matter found in the alveolar macrophage cells also known as dust cells that help stop foreign materials like particles and bacteria from entering the lungs tiny worms test nanoparticles for safety The researchers write that their results suggest humans are routinely exposed to carbon nanotubes They also suggested previous studies that link the carbon content of airway macrophages and the decline of lung function should be reconsidered in light of the new findings Moussa confirms his lab will continue to study the impact of man made nanotubes on health The cells were taken from 69 randomly selected asthma patients aged 2 to 17 who underwent routine fiber optic bronchoscopies as part of their treatment For ethical reasons no cells from healthy patients were analyzed but because nanotubes were found in all of the samples the study led the researchers to conclude that carbon nanotubes are likely to be found in everybody Similar to asbestos The study notes but does not make definitive conclusions about

  • Pacific coast sees spike in methane bubble plumes - Futurity

  • Poll shows Americans are really confused about gun laws - Futurity
    PhD candidate who conducted the research with Peter Aronow assistant professor of political science at Yale University discussed the findings with YaleNews Where did the idea for the survey originate After the massacre at Sandy Hook Elementary School there was a lot of debate about tightening gun control laws and various polls showed widespread support for it Finally a bill was proposed in Congress the Manchin Toomey bill that would have closed existing loopholes in the background check system But the bill didn t attract enough votes in the Senate to overcome a filibuster and even if it had passed the Senate it would have been dead on arrival in the Republican controlled House of Representatives So I looked at the public opinion data and wondered how in a democracy something so overwhelmingly favored by the public could fail to pass I had seen the Quinnipiac poll that showed that 92 percent of Americans favor universal background checks but then there are other polls that show that Americans are about equally divided over whether gun control laws should be stricter or not So it seemed like there was a kind of disconnect there because if most people favor universal background checks and we don t have universal background checks then that should imply that most people favor stricter gun laws And I had seen other surveys that showed a large proportion of people about half think that universal background checks are already the law They are unaware of the loopholes for sales at guns shows or over the internet So I was inspired to put these things together and determine whether the ignorance of the legal status quo is what is driving the fact that there has not been new federal legislation in spite of this seemingly overwhelming public support What did you ask We asked four questions We asked whether gun laws should be made stricter less strict or kept as they are and whether people favor or oppose universal background checks Then we asked people about the current law for background checks whether they are required for all gun purchases some gun purchase or no gun purchases some gun purchases being the correct answer Finally we asked whether people would vote for an otherwise qualified candidate who did not share their position on gun control There is an existing literature suggesting that there is an engagement gap or an intensity gap between proponents and opponents of gun control such that a majority of the country supports gun control but those who oppose it care more strongly about it and are more likely to base their vote on the gun issue What did you find We found that 77 percent of Americans favor universal background checks but only 53 percent say they favor stricter gun laws That s a quarter of the population at least that has this inconsistent position of wanting universal background checks which we do not have and which would represent a tightening of gun laws

  • How to hide from the internet's surveillance machine - Futurity
    the line to say jack up the price on a plane ticket the next time you re making travel arrangements serve up a selection of higher end goods the next time you search on an online retailer s site or on the flip side make it tougher for you to get a loan if something about your data gets flagged as a credit risk This is a clear example of what Brunton and coauthor Helen Nissenbaum also a professor at NYU describe as information asymmetry where as they write the companies collecting data know much about us and we know little about them or what they can do The surveillance background It s not just that we haven t agreed to having our personal information collected it s that the invisible processes of dossier building are so complex and their consequences so difficult to predict that it would be virtually impossible to understand exactly what we re being asked to consent to Whereas NSA snooping makes headlines other forms of quiet surveillance go unnoticed and unregulated to the benefit of shadowy entities making bank in the data economy or even police using software to calculate citizens threat scores Machines don t forget Brunton says Suppose you have an agreement with one company the best company run by the best people he says but then they go bankrupt or get subpoenaed or acquired Your data ends up on the schedule of assets and then you don t know where it might end up Do your friends give your data to third parties To be clear the authors whose manifesto irked critics who argue that these kinds of transactions are what finance the free internet aren t against online advertising per se Before ad networks started the surveillance background Nissenbaum explains there was traditional advertising where Nike could buy an ad space on say the New York Times website or contextual advertising where Nike would buy space on Sports Illustrated There were plenty of ways of advertising that didn t involve tracking people Nowadays though Brunton says Many online sites that produce content you use and enjoy don t get that much money out of the advertising and yet there s a whole galaxy of third party groups on the back end swapping data back and forth for profit in a way that s not necessarily more effective for the merchant the content provider or you Then add on top of it all that the data can be misused and you have a network that is less secure and built around surveillance I think that starts to shift the balance in favor of taking aggressive action That s where obfuscation defined in the book as the production of noise modeled on an existing signal in order to make a collection of data more ambiguous confusing harder to exploit more difficult to act on and therefore less valuable comes in TrackMeNot for example one of several elegant obfuscation tools designed by Nissenbaum and
