On Monday, Australian telecommunications company Telstra has introduced dual carrier HSPA+ standard for broadband Internet business customers in the Next G network. This is the first time this technology is being introduced on national scale. The bandwidths the users can deploy increased into two to three times, with Telstra becoming the world’s fastest national mobile broadband service. The switch started with enabling the service for premium users. After some feedback, Telstra may expand the plan.

The higher speeds for wireless are intended to simplify and ease multitasking of users.

John Paitaridis, Telstra’s executive director, network products and services in Enterprise & Government, said “One of the reasons we decided to launch first to Enterprise And Government and Business customers is that clients are saying that their ability to access applications quicker makes a difference to their business and when they start to equate time savings and doing calculations around productivity it does become a return on investment.”

Telstra Business Group Managing Director Deena Shiff also stated that the efforts aren’t as sudden as it might seem, having feedback of many users as the base.

Australians are telling us they can’t afford to be tied to the desk all day and these new speeds mean they can now access mobile broadband at speeds typically reserved for the office. We have been deploying the high-speed capability in the network since December 2009 and now, with the launch of the new Ultimate USB Modem, these new speeds are available to customers across all capital city CBDs and associated airports, selected metropolitan areas and in more than 100 regional locations. These high-speed zones cover approximately 50 per cent of the Australian population and match the areas of highest customer demand and will make the frustration of waiting around for files to download a thing of the past. In other metropolitan and regional areas, the Telstra Ultimate USB Modem offers typical download speeds ranging from 550kbps up to 8Mbps… Our customers have told us that they want higher speed mobile broadband so they can work more flexibly outside of the office and we are delighted to be the first in the world to offer these new blistering speeds on a national network. The new Telstra Ultimate USB Modem provides customers with the speeds needed to handle large files, multi-task and update cloud-hosted applications effortlessly on the go when they are in a coverage area.

Previous modems were able to reach peak speed 21Mbps, with real life speeds ranging from 0.5Mbps to 8 Mbps. The theoretically expected maximum of the new technology is 42Mbps with user speeds varying between 1.1 and 20 Mbps. The new speed is twice as fast. This is caused by that the dual-carrier “Evolved High-Speed Packet Access” technology allows networks to send and receive wireless data using two channels simultaneously. This technology can be deployed on Next G networks. Telstra switched to them in February, thus making the switch to HSPA possible now.

Telstra delayed the implementation of the new technology until elections end. This decision was intended to avoid wrong interpretation of them by Coalition. Coalition’s claims include that wireless networks can be an alternative to the Labor party “fibre-to-the-home” proposal to introduce more expensive wired Internet. The announcement of the new technology, initially planned on August 25, was delayed, with Telstra spokesman Craig Middleton explaining, “We just didn’t want to feel like we were influencing the [telecommunications] debate.”

The political parties have different plans on development and funds on the Internet. The Labor party aims to spend AUD 43 billion to bring 1 Gbps wired Internet nationwide, and the Coalition plans to spend AUD 6 billion to introduce a variety of improvements including upgrade of existing copper Internet as well as expansion of wireless Internet to support 12Mbps. Opposition leader Tony Abbott has said in the past that Australians shouldn’t assume wireless technologies won’t ever be comparable to fixed-line technology. Telstra’s upgrade shows that wireless broadband is reaching the 100 Mbps minimum speeds promised by Labor’s national broadband network.

Telstra has only 2000 devices which support the new technology. This is why the opportunity to try it out is being given only to the Business plan customers, and they receive it for the same price as they were paying for the previous NextG plan. Since October 5, the device will be available for sale, with the Business customers able to buy it with 75% discount and a prepaid data allowance. The upgrade is expected to cover roughly 50% of the population. This is happening at the same time as one of Telstra’s competitors Vodafone is doubling data download quotas on mobile cap plans.

As some testing showed, real life download speeds reached only about the half of the maximum. Telstra executive director of wireless Mike Wright explained that the predicted figures were the estimates, with real life speeds lower due to interfering environmental conditions: “It’s possible to achieve better than the typical user speed claims, but those claims occur in the ideal network environment with good signal quality. When you’re out on the streets you get a lot of variation where the network is subject to signal quality, your location and the network load.”

Monday saw the latest edition of the vetted version of Wikipedia, which is aimed at educational use, go quietly online. The extensively revised version covers over five thousand topics, targeting the eight to seventeen years age group. Partnerships with the Shuttleworth Foundation and the Hole in the Wall project will see it distributed in South Africa and India as well as copies being available globally via the offices of SOS Children UK’s umbrella organisation, SOS Kinderdorf worldwide.

First launched in 2006 as a 4,000 article edition, the extract of Wikipedia has employed hi-tech distribution methods, as well as offering a website version which has steadily climbed up in ranking to above other reviewed Wikipedia rivals and copies; the 2007 version was available on the BitTorrent peer to peer network to keep distribution costs down and was equivalent to a fifteen-volume printed encyclopedia. Monday’s release is compared to a twenty-volume print edition.

Key to the process for selecting articles is the English National Curriculum and similar educational standards around the world. The initial vision was to bring this wealth of knowledge to schools where access to the Internet was poor or unavailable, but copies of Wikipedia for Schools can be found on many first world school intranets and web servers. Among the compelling reasons to adopt the project are the vetting and additional study materials which overcome the oft-publicised concerns many educators have with the million article plus Wikipedia that anyone can edit.

In today’s press release announcing the launch, Wikimedia Foundation Executive Director Sue Gardner expressed delight at seeing the project bring out a new version, “Our goal is to make Wikipedia accessible to as many people as possible around the world, and SOS Children is a great partner that helps us make that happen. Wikipedia is released under a free content license so that individuals and institutions can easily adapt, reuse and customize its content: we encourage others, like SOS Children, to do exactly that.”

Running 192 schools in the developing world, SOS Children sees Wikipedia for Schools as a key piece in fulfilling the educational aspect of their mission. SOS Children’s Chairwoman, Mary Cockcroft gave us an introduction and, a Wikipedia administrator himself, the charity’s CEO Andrew Cates spoke to Wikinews at length about the project.

You are part of SOS-Kinderdorf International, can you explain a little about how this works in terms of distributing funds raised in the UK and involving UK citizens in work outside the country?

Mary Cockcroft: SOS Children[‘s Villages] is a “club” of member charities in 130 countries helping orphans and vulnerable children. The club elects SOS-Kinderdorf International as secretary. SOS is a large organisation whose members in aggregate turned over $1bn in 2007, and whose projects include owning and running 192 schools and family-based care for 70,000 children. However much of these funds are raised locally, with for example the member charities in each of India, Pakistan and South Africa raise considerably more funds in their own country than SOS UK does from the UK. Nonetheless SOS Children UK principally raises funds to finance projects in the developing world, and has only financially small projects in the UK (such as the Schools Wikipedia, which is very low cost because of extensive use of volunteers). This year we expect about 80% of our UK income will leave the UK for overseas SOS associations, and some of the remaining 20% will pay for project oversight. We do not spend money in the UK on Direct Mail or TV advertising. Our UK office is involved in overseeing projects we finance and a small number of high-skilled volunteers from the UK help overseas. However around 98% of SOS staff worldwide are local nationals, as are most volunteers.

((WN)) How much work does the UK charity actually carry out within the home country? Are there failings within the government system for orphans and other needy children that you feel obliged to remedy?

MC: We are deeply unhappy about the situation of children in out-of-home care in the UK. However our care model of 168 hour-a-week resident mothers does not fit with the UK philosophy for children without parental care. Internationally SOS always has a policy of sharing best practice and we are working to improve understanding of our way of working, which appears to us to have far better outcomes than the existing one in the UK. Ultimately though the legal responsibility for these children lies with government and we cannot remedy anything without their invitation.

((WN)) Who first came up with the idea of doing a vetted Wikipedia extract? What was the impetus? Was it more for the developing world than first world?

Andrew Cates: I honestly cannot remember who first suggested it, but it came from somewhere in the Wikipedia community rather than from the charity. The original product was very much pitched at the developing world where the Internet is only available if at all over an expensive phone line. I worked in West Africa 1993-1996 and I know well at how thirsty for knowledge people are and how ingenious they will be in overcoming technical obstacles if the need for infrastructure is removed.

((WN)) In reading past year’s announcements there’s some pride in the project being picked up and used in the first world, was this expected or a pleasant surprise?

AC: It was a pleasant surprise. I don’t think we had realised what the barriers schools faced in using the main Wikipedia were. It isn’t just pupils posting material about teachers or meeting strangers: the “Random Article” button on every page could potentially deliver an article on hardcore porn. We had already started when discussion broke on banning Wikipedia from classrooms and I am sure we benefited from it.

((WN)) Can you give an outline of the selection and vetting process? Is it primarily Wikipedians working on this, or are people from the educational establishment brought in?

AC: It was a long and painful process, even with a really good database system. Articles were taken into the proposal funnel from three main sources: direct proposals for inclusion from Wikipedians, lists which came from the Release Version team and proposals drawn up from working through National Curriculum subjects by SOS volunteers. In a few cases where we felt articles were missing we asked the community to write them (e.g. Portal:Early Modern Britain, which is a curriculum subject, was kindly written just for us): These “proposals” were then looked at by mainly SOS volunteers (some onwiki, some offline). Our offices are in the middle of Cambridge and we get high quality volunteers, who skim read each article and then compared two versions from the article history by credible WP editors a significant period apart (this picks up most graffiti vandalism which runs at about 3% of articles). Once they had identified a “best” version they marked any sections or text strings for deletion (sections which were just a list of links to other articles not included, empty sections, sex scandals etc). A substantial sample of each volunteers work was then doubled checked for quality by one of two office staff (of whom I was one). We then have a script which does some automated removals and clean ups. Once we had a selection we posted it to relevant wikiprojects and a few “experts” and got any extra steers.

((WN)) Will you be making use of BitTorrent for distribution again this year? Was it a success in 2007?

AC: BitTorrent was a bit disappointing in that it got us the only substantial criticisms we received online. A lot of people find it too much effort to use. However for the period we offered a straight http: download we had huge problems with spiders eating vast bandwidth (the file is 3.5G: a few thousand rogue spider downloads and it starts to hurt). As per last year therefore our main two channels will be free download by BitTorrent and mailing the DVDs free all over the world. At a pinch we will (as before) put straight copies up for individuals who cannot get it any other way, and we have some copies on memory sticks for on distributors.

((WN)) Is it your opinion that the UK Government should be encouraging the adoption of projects like this as mainstream educational resources?

AC: Clearly yes. We have had a very enthusiastic reaction from schools and the teaching community. We think every school should have an intranet copy. We expect the Government to catch on in a few years. That is not to say that Wikipedia is as good as resources developed by teachers for teachers such as lesson plans etc. but it is a fantastic resource.

((WN)) You’re a Wikipedia administrator, all too often a thankless task. What prompted you to get involved in the first place? What are the most notable highs and lows of your involvement with the project?

AC: Funnily the thing I have found most amazing about Wikipedia is not widely discussed, which is the effect of Wikipedia policies on new editors. I have seen countless extreme POV new editors, who come in and try to get their opinions included slowly learn not only that there are other opinions to consider but that elements of their own opinion which are not well founded. Watching someone arrive often (on pages on religions for example) full of condemnation for others, gradually become understanding and diplomatic is one of the biggest buzzes there is. The downside though is where correcting things which are wrong is too painfully slow because you need to find sources. I was a post-doc at Cambridge University in combustion and I know the article on Bunsen burners has several really significant errors concerning the flame structure and flow structure. But sadly I cannot correct it because I am still looking around for a reliable source.

((WN)) Do you believe schools should encourage students to get involved contributing to the editable version of Wikipedia? Does SOS Children encourage those who are multilingual to work on non-English versions?

AC: I think older students have a lot to learn from becoming involved in editing Wikipedia.

((WN)) To close, is there anything you’d like to add to encourage use of Wikipedia for Schools, or to persuade educators to gain a better understanding of Wikipedia?

AC: I would encourage people to feed back to the project online or via the charity. The Wikipedia community set out to help educate the world and are broadly incredibly well motivated to help. As soon as we understand what can be done to improve things people are already on the task.

((WN)) Thank you for your time.

Former Australian Prime Minister John Howard supported the launch of a new book “How to Get Expelled from School: A Guide to Climate Change for Pupils, Pundits and Parents”, authored by geology professor Ian Plimer. The book includes 101 questions for students to use to challenge their climate science teachers.

The book follows Professor Plimer’s 2009 “Heaven and Earth”. Professor Plimer said the previous book received feedback from parents concerned about education. This prompted him to address the next book to children. He said, “After Heaven and Earth came out I had many parents write to me and say, ‘Look, what do we do, our kids are being fed activism. I want my children to have the basics of scientists, I don’t want to be fed activism'”.

Mr Howard advocated emissions trading in 2007. He says he considered it feasible if the rest of the world acted too, otherwise to introduce carbon trading plans would risk Australian industries. “I proposed an emissions trading scheme and some people say, ‘Well why on earth did you do that?’ [It was] predicated on the rest of the world moving in the same direction and also predicated on a structure that would preserve the international competitiveness of those industries that gave our country a competitive trade advantage, it could do no harm”, he explained. “[It’s] hard to understand how we would do anything to put” Australia’s competitive advantage due to natural resources “at risk. The reality is we are doing that at the moment. The carbon tax is not being replicated in other countries.”

Professor Ian Enting, complex system scientist at the University of Melbourne, said the book includes scientific errors and insufficient references. Margaret Watts, president of the Science Teachers’ Association of New South Wales, said the educational bias claim is mistaken. “What science teachers do”, she said, “is put all of the facts, pro and con, against any topic, whatever it is, and show the children how to work through the evidence”.

Professor Plimer said of the 101 questions in his book, “They’re questions that kids should be asking of teachers, because if the teacher can answer it means they might know something about the subject. If they can’t, or start to promote ideology, it shows that our schools have been captured. Parents are telling me that schools have been captured by a lot of activists and kids are being fed stuff that is not relevant to the real world.”

Nick Bos, of the University of Helsinki, studies “the amazing adaptations social insects have evolved in order to fight the extreme parasite pressure they experience”. In a recently-accepted Evolution paper Bos and colleagues describe ants appearing to self-medicate.

The team used Formica fusca, an ant species that can form thousand-strong colonies. This common black ant eats other insects, and also aphid honeydew. It often nests in tree stumps or under rocks and foraging workers can sometimes be spotted climbing trees.

Some ants were infected with Beauveria bassiana, a fungus. Infected ants chose food laced with toxic hydrogen peroxide, whereas healthy ants avoided it. Hydrogen peroxide reduced infected ant fatalities by 15%, and the ants varied their intake depending upon how high the peroxide concentration was.

In the wild, Formica fusca can encounter similar chemicals in aphids and dead ants. The Independent reported self-medicating ants a first among insects.

Bos obtained his doctorate from the University of Copenhagen. He began postdoctoral research at Helsinki in 2012. He also runs the AntyScience blog. The blog aims to help address “a gap between scientists and ‘the general public’.” The name is a pun referencing ants, its primary topic, science, and “non-scientific” jargon-free communication. He now discusses his work with Wikinews.

((Wikinews)) What first attracted you to researching ants?

Nick Bos Me and a studymate were keeping a lot of animals during our studies, from beetles, to butterflies and mantids, to ants. We had the ants in an observation nest, and I could just look at them for hours, watching them go about. This was in my third year of Biology study I think. After a while I needed to start thinking about an internship for my M.Sc. studies, and decided to write a couple of professors. I ended up going to the Centre for Social Evolution at the University of Copenhagen where I did a project on learning in Ants under supervision of Prof. Patrizia d’Ettorre. I liked it so much there I ended up doing a PhD and I’ve been working on social insects ever since.

((Wikinews)) What methods and equipment were used for this investigation?

NB This is a fun one. I try to work on a very low budget, and like to build most of the experimental setups myself (we actually have equipment in the lab nicknamed the ‘Nickinator’, ‘i-Nick’ and the ‘Nicktendo64’). There’s not that much money in fundamental science at the moment, so I try to cut the costs wherever possible. We collected wild colonies of Formica fusca by searching through old tree-trunks in old logging sites in southern Finland. We then housed the ants in nests I made using Y-tong [aerated concrete]. It’s very soft stone that you can easily carve. We carved out little squares for the ants to live in (covered with old CD covers to prevent them escaping!). We then drilled a tunnel to a pot (the foraging arena), where the ants got the choice between the food with medicine and the food without.

We infected the ants by preparing a solution of the fungus Beauveria bassiana. Afterwards, each ant was dipped in the solution for a couple of seconds, dried on a cloth and put in the nest. After exposing the ants to the fungus, we took pictures of each foraging arena three times per day, and counted how many ants were present on each food-source.

This gave us the data that ants choose more medicine after they have been infected.

The result that healthy ants die sooner when ingesting ROS [Reactive Oxygen Species, the group of chemicals that includes hydrogen peroxide] but infected ants die less was obtained in another way (as you have to ‘force feed’ the ROS, as healthy ants, when given the choice, ignore that food-source.)

For this we basically put colonies on a diet of either food with medicine or without for a while. And afterwards either infected them or not. Then for about two weeks we count every day how many ants died. This gives us the data to do a so-called survival analysis.

We measured the ROS-concentration in the bodies of ants after they ingested the food with the medicine using a spectrophotometer. By adding certain chemicals, the ROS can be measured using the emission of light of a certain wave-length.

The detrimental effect of ROS on spores was easy to measure. We mixed different concentrations of ROS with the spores, plated them out on petridishes with an agar-solution where fungus can grow on. A day after, we counted how many spores were still alive.

((Wikinews)) How reliable do you consider your results to be?

NB The results we got are very reliable. We had a lot of colonies containing a lot of ants, and wherever possible we conducted the experiment blind. This means the experimenter doesn’t know which ants belong to which treatment, so it’s impossible to influence the results with ‘observer bias’. However, of course this is proof in just one species. It is hard to extrapolate to other ants, as different species lead very different lives.

((Wikinews)) Where did the ants and fungus you used come from? How common are they in the wild?

NB For ants, see above about the collection.

This species of fungus does appear in Finland, but we chose to use a different strain from Denmark (with thanks to Prof. J. Eilenberg and the laboratory technician Louise Lee Munch Larsen from the University of Copenhagen). Animals can adapt to local strains (‘local adaptation’), and just to make sure we thought it would be good to use a strain of fungus that the ants definitely did not evolve specific resistances against. This means that the reaction of the ants (to self-medicate) is very likely to be a general response, and not just against their local fungal enemies.

((Wikinews)) Are there any ethical considerations around exposing ants to toxins and parasites?

NB Legally, no. Insects do not have any ‘rights’ as such regarding ethics. That said, we do take measures to not make them ‘suffer unnecessarily’. For example, dissections are done when the ants are anesthetized (either by CO2 or Ice), and when ants need to be killed, we do it in alcohol, which kills the ants in a matter of seconds. So while the ants do not have ‘rights’ as such, we still try to handle them with as much respect as possible (even though the experiment involves infecting them with a deadly fungus).

But even though the 12,000 ants in our study sounds like a lot (and it is), this is negligible in the ‘grand scheme of things’. It has been calculated that in the Netherlands alone, nearly a trillion insects die against just the licence-plates of cars every six months. I don’t own a car, so that means I’m excused right? 😉

((Wikinews)) This is the first evidence for self-medicating insects. How widespread do you think this phenomenon could be in reality?

NB It’s not actually the first evidence for self-medication in insects. Moths and fruit flies definitely do it, and there’s evidence in honey bees and bumble-bees as well. So it seems to be quite wide-spread in the insect world. I have no doubt that as time goes on, there will be more and more cases documented. Insects (and animals in general) seem to be quite good at taking care of themselves.

((Wikinews)) How might ants locate healing substances in the wild?

NB Very good question. This is something that’s important to know. If they would only do it in the lab, the behaviour wouldn’t be very interesting. We have some guesses where they might get it from, but at the moment we don’t know yet. That said, I plan to investigate this question (among others) further [in] the next couple of years.

((Wikinews)) For your PhD you researched ants’ scent-based communications. Could healthy ants perhaps tell other ants are infected and encourage this behaviour?

NB There’s not much known about this. There’s conflicting evidence about whether sick ants actually smell different from healthy ones or not. At the moment it seems that sick ants mostly take care of the problem themselves. Sick ants stop most interaction with nestmates and especially brood, and leave the nest to die in isolation. This is probably for reducing chance of infecting nestmates, but of course it also reduces the work load of their nest-mates, as their corpse doesn’t have to be dragged out etc.

So as an answer to the question, I would find it unlikely that such a behaviour would evolve, but it’s not known yet.

((Wikinews)) Ants generally avoided the peroxide if they were healthy, but in some circumstances might they try to build resistance against infection in advance?

NB Who knows? Also not known yet unfortunately. That said, there is a very interesting study about resin collection in ants. Wood ants collect tree-resin, which has anti-microbial properties. They collect this even if not infected, and when you infect them, they don’t collect more of the resin than normal. So basically it seems like they collect it in order to keep diseases out of the nest, so they stop the disease before it can actually infect them.

((Wikinews)) Are there plans to follow this research up? Might you research other species? Other substances?

NB I first want to find out where they get it from in nature. There might be many sources of medicine (recent evidence suggests that tobacco plays a similar role for bumble bees). Dalial Freitak, who is also on this paper is currently running tests with Ph.D. student Siiri Fuchs (who is also on the paper) with other substances to see if any have the same effect as H2O2 [hydrogen peroxide].

Once the behaviour has been well described in this species of ant, I might do a comparison with other species. For example, once we find the source of the medicine in nature… would species without access to this source also have evolved the same behaviour in the lab? And if so… where would they get it from?

Also… can ants medicate their friends? 🙂

((Wikinews)) What other research are you working on right now?

NB Phew…lots! 🙂

I still have some questions left unanswered from my Ph.D. work related to how ants recognize who is a friend and who isn’t. I also started collaborating with Prof. Michael Poulsen from the University of Copenhagen on immunity in fungus-growing termites, as well as their chemical recognition abilities. Furthermore we’re working on social parasitism in wood-ants (ants have lots of animals exploiting the nest for shelter and resources, which all somehow have to get in to the fortress without getting killed).

Late last month, the American Civil Liberties Union (ACLU) and Electronic Frontier Foundation (EFF) filed objections to the United States Government’s ‘secret’ attempts to obtain Twitter account information relating to WikiLeaks. The ACLU and EFF cite First and Fourth amendment issues as overriding reasons to overturn government attempts to keep their investigation secret; and, that with Birgitta Jonsdottir being an Icelandic Parliamentarian, the issue has serious international implications.

The case, titled “In the Matter of the 2703(d) Order Relating to Twitter Accounts: Wikileaks, Rop_G, IOERROR; and BirgittaJ“, has been in the EFF’s sights since late last year when they became aware of the US government’s attempts to investigate WikiLeaks-related communications using the popular microblogging service.

The key objective of this US government investigation is to obtain data for the prosecution of Bradley Manning, alleged to have supplied classified data to WikiLeaks. In addition to Manning’s Twitter account, and that of WikiLeaks (@wikileaks), the following three accounts are subject to the order: @ioerror, @birgittaj, and @rop_g. These, respectively, belong to Jacob Apelbaum, Birgitta Jonsdottir, and Rop Gonggrijp.

Birgitta is not the only non-US citizen with their Twitter account targeted by the US Government; Gonggrijp, a Dutch ‘ex-hacker’-turned-security-expert, was one of the founders of XS4ALL – the first Internet Service Provider in the Netherlands available to the public. He has worked on a mobile phone that can encrypt conversations, and proven that electronic voting systems can readily be hacked.

In early March, a Virginia magistrate judge ruled that the government could have the sought records, and neither the targeted users, or the public, could see documents submitted to justify data being passed to the government. The data sought is as follows:

1. Personal contact information, including addresses
2. Financial data, including credit card or bank account numbers
3. Twitter account activity information, including the “date, time, length, and method of connections” plus the “source and destination Internet Protocol address(es)”
4. Direct Message (DM) information, including the email addresses and IP addresses of everyone with whom the Parties have exchanged DMs

The order demands disclosure of absolutely all such data from November 1, 2009 for the targeted accounts.

The ACLU and EFF are not only challenging this, but demanding that all submissions made by the US government to justify the Twitter disclosure are made public, plus details of any other such cases which have been processed in secret.

Bradley Manning, at the time a specialist from Maryland enlisted with the United States Army’s 2nd Brigade, 10th Mountain Division, was arrested in June last year in connection with the leaking of classified combat video to WikiLeaks.

The leaked video footage, taken from a US helicopter gunship, showed the deaths of Reuters staff Saeed Chmagh and Namir Noor-Eldeen during a U.S. assault in Baghdad, Iraq. The wire agency unsuccessfully attempted to get the footage released via a Freedom of Information Act request in 2007.

When WikiLeaks released the video footage it directly contradicted the official line taken by the U.S. Army asserting that the deaths of the two Reuters staff were “collateral damage” in an attack on Iraqi insurgents. The radio chatter associated with the AH-64 Apache video indicated the helicopter crews had mistakenly identified the journalists’ equipment as weaponry.

The US government also claims Manning is linked to CableGate; the passing of around a quarter of a million classified diplomatic cables to WikiLeaks. Manning has been in detention since July last year; in December allegations of torture were made to the United Nations High Commissioner for Human Rights regarding the conditions under which he was and is being detained.

Reports last month that he must now sleep naked and attend role call at the U.S. Marine facility in Quantico in the same state, raised further concern over his detention conditions. Philip J. Crowley, at-the-time a State Department spokesman, remarked on this whilst speaking at Massachusetts Institute of Technology; describing the current treatment of Manning as “ridiculous and counterproductive and stupid”, Crowley was, as a consequence, put in the position of having to tender his resignation to Secretary of State Hillary Clinton.

Despite his native Australia finding, in December last year, that Assange’s WikiLeaks had not committed any criminal offences in their jurisdiction, the U.S. government has continued to make ongoing operations very difficult for the whistleblower website.

The result of the Australian Federal Police investigation left the country’s Prime Minister, Julia Gillard, having to retract a statement that WikiLeaks had acted “illegally”; instead, she characterised the site’s actions as “grossly irresponsible”.

Even with Australia finding no illegal activity on the part of WikiLeaks, and with founder Julian Assange facing extradition to Sweden, U.S. pressure sought to hobble WikiLeaks financially.

Based on a State Department letter, online payments site PayPal suspended WikiLeaks account in December. Their action was swiftly followed by Visa Europe and Mastercard ceasing to handle payments for WikiLeaks.

The online processing company, Datacell, threatened the two credit card giants with legal action over this. However, avenues of funding for the site were further curtailed when both Amazon.com and Swiss bank PostFinance joined the financial boycott of WikiLeaks.

Assange continues, to this day, to argue that his extradition to Sweden for questioning on alleged sexual offences is being orchestrated by the U.S. in an effort to discredit him, and thus WikiLeaks.

Wikinews consulted an IT and cryptography expert from the Belgian university which developed the current Advanced Encryption Standard; explaining modern communications, he stated: “Cryptography has developed to such a level that intercepting communications is no longer cost effective. That is, if any user uses the correct default settings, and makes sure that he/she is really connecting to Twitter it is highly unlikely that even the NSA can break the cryptography for a protocol such as SSL/TLS (used for https).”

Qualifying this, he commented that “the vulnerable parts of the communication are the end points.” To make his point, he cited the following quote from Gene Spafford: “Using encryption on the Internet is the equivalent of arranging an armored car to deliver credit card information from someone living in a cardboard box to someone living on a park bench.“

Continuing, the Katholieke Universiteit Leuven (KUL) expert explained:

“In the first place, the weak point is Twitter itself; the US government can go and ask for the data; companies such as Twitter and Google will typically store quite some information on their users, including IP addresses (it is known that Google deletes the last byte of the IP address after a few weeks, but it is not too hard for a motivated opponent to find out what this byte was).“

“In the second place, this is the computer of the user: by exploiting system weaknesses (with viruses, Trojan horses or backdoors in the operating system) a highly motivated opponent can enter your machine and record your keystrokes plus everything that is happening (e.g. the FBI is known to do this with the so-called Magic Lantern software). Such software is also commercially available, e.g. for a company to monitor its employees.“

“It would also be possible for a higly motivated opponent to play “man-in-the-middle”; that means that instead of having a secure connection to Twitter.com, you have a secure connection to the attacker’s server, who impersonates Twitter’s and then relays your information to Twitter. This requires tricks such as spoofing DNS (this is getting harder with DNSsec), or misleading the user (e.g. the user clicks on a link and connects to tw!tter.com or Twitter.c0m, which look very similar in a URL window as Twitter.com). It is clear that the US government is capable of using these kind of tricks; e.g., a company has been linked to the US government that was recognized as legitimate signer in the major browsers, so it would not be too large for them to sign a legitimate certificate for such a spoofing webserver; this means that the probability that a user would detect a problem would be very low.“

“As for traffic analysis (finding out who you are talking to rather than finding out what you are telling to whom), NSA and GCHQ are known to have access to lots of traffic (part of this is obtained via the UK-USA agreement). Even if one uses strong encryption, it is feasible for them to log the IP addresses and email addresses of all the parties you are connecting to. If necessary, they can even make routers re-route your traffic to their servers. In addition, the European Data Retention directive forces all operators to store such traffic data.“

“Whether other companies would have complied with such requests: this is very hard to tell. I believe however that it is very plausible that companies such as Google, Skype or Facebook would comply with such requests if they came from a government.“

“In summary: unless you go through great lengths to log through to several computers in multiple countries, you work in a clean virtual machine, you use private browser settings (don’t accept cookies, no plugins for Firefox, etc.) and use tools such as Tor, it is rather easy for any service provider to identify you.“

“Finally: I prefer not to be quoted on any sentences in which I make statements on the capabilities or actions of any particular government.“

Wikinews also consulted French IT security researcher Stevens Le Blond on the issues surrounding the case, and the state-of-the-art in monitoring, and analysing, communications online. Le Blond, currently presenting a research paper on attacks on Tor to USENIX audiences in North America, responded via email:

Were the US Government to obtain the sought data, it would seem reasonable the NSA would handle further investigation. How would you expect them to exploit the data and expand on what they receive from Twitter?

• Le Blond: My understanding is that the DOJ is requesting the following information: 1) Connection records and session times 2) IP addresses 3) e-mail addresses 4) banking info

By requesting 1) and 2) for Birgitta and other people involved with WikiLeaks (WL) since 2009, one could derive 2 main [pieces of] information.

First, he could tell the mobility of these people. Recent research in networking shows that you can map an IP address into a geographic location with a median error of 600 meters. So by looking at changes of IP addresses in time for a Twitter user, one could tell (or at least speculate about) where that person has been.

Second, by correlating locations of different people involved with WL in time, one could possibly derive their interactions and maybe even their level of involvement with WL. Whether it is possible to derive this information from 1) and 2) depends on how this people use Twitter. For example, do they log on Twitter often enough, long enough, and from enough places?

My research indicates that this is the case for other Internet services but I cannot tell whether it is the case for Twitter.

Note that even though IP logging, as done by Twitter, is similar to the logging done by GSM [mobile phone] operators, the major difference seems to be that Twitter is subject to US regulation, no matter the citizenship of its users. I find this rather disturbing.

Using 3), one could search for Birgitta on other Internet services, such as social networks, to find more information on her (e.g., hidden accounts). Recent research on privacy shows that people tend to use the same e-mail address to register an account on different social networks (even when they don’t want these accounts to be linked together). Obviously, one could then issue subpoenas for these accounts as well.

I do not have the expertise to comment on what could be done with 4).

((WN)) As I believe Jonsdottir to be involved in the Icelandic Modern Media Initiative (IMMI), what are the wider implications beyond the “WikiLeaks witchhunt”?

• Le Blond: Personal data can be used to discredit, especially if the data is not public.

Having been alerted to the ongoing case through a joint press release by the ACLU and EFF, Wikinews sought clarification on the primary issues which the two non-profits saw as particularly important in challenging the U.S. Government over the ‘secret’ court orders. Rebecca Jeschke, Media Relations Director for the EFF, explained in more detail the points crucial to them, responding to a few questions from Wikinews on the case:

((WN)) As a worse-case, what precedents would be considered if this went to the Supreme Court?

• Rebecca Jeschke: It’s extremely hard to know at this stage if this would go to the Supreme Court, and if it did, what would be at issue. However, some of the interesting questions about this case center on the rights of people around the world when they use US Internet services. This case questions the limits of US law enforcement, which may turn out to be very different from the limits in other countries.

((WN)) Since this is clearly a politicised attack on free speech with most chilling potential repercussions for the press, whistleblowers, and by-and-large anyone the relevant U.S. Government departments objects to the actions of, what action do you believe should be taken to protect free speech rights?

• Jeschke: We believe that, except in very rare circumstances, the government should not be permitted to obtain information about individuals’ private Internet communications in secret. We also believe that Internet companies should, whenever possible, take steps to ensure their customers are notified about requests for information and have the opportunity to respond.

((WN)) Twitter via the web, in my experience, tends to use https:// connections. Are you aware of any possibility of the government cracking such connections? (I’m not up to date on the crypto arms race).

• Jeschke: You don’t need to crack https, per se, to compromise its security. See this piece about fraudulent https certificates:

Iranian hackers obtain fraudulent https — EFF website.

((WN)) And, do you believe that far, far more websites should – by default – employ https:// connections to protect people’s privacy?

• Jeschke: We absolutely think that more websites should employ https! Here is a guide for site operators: (See external links, Ed.)

Finally, Wikinews approached the Icelandic politician, and WikiLeaks supporter, who has made this specific case a landmark in how the U.S. Government handles dealings with – supposedly – friendly governments and their elected representatives. A number of questions were posed, seeking the Icelandic Parliamentarian’s views:

((WN)) How did you feel when you were notified the US Government wanted your Twitter account, and message, details? Were you shocked?

• Birgitta Jonsdottir: I felt angry but not shocked. I was expecting something like this to happen because of my involvement with WikiLeaks. My first reaction was to tweet about it.

((WN)) What do you believe is their reasoning in selecting you as a ‘target’?

• Jonsdottir: It is quite clear to me that USA authorities are after Julian Assange and will use any means possible to get even with him. I think I am simply a pawn in a much larger context. I did of course both act as a spokesperson for WikiLeaks in relation to the Apache video and briefly for WikiLeaks, and I put my name to the video as a co-producer. I have not participated in any illegal activity and thus being a target doesn’t make me lose any sleep.

((WN)) Are you concerned that, as a Member of Parliament involved in the Icelandic Modern Media Initiative (IMMI), the US attempt to obtain your Twitter data is interfering with planned Icelandic government policy?

• Jonsdottir: No

((WN)) In an earlier New York Times (NYT) article, you’re indicating there is nothing they can obtain about you that bothers you; but, how do you react to them wanting to know everyone you talk to?

• Jonsdottir: It bothers me and according to top computer scientists the government should be required to obtain a search warrant to get our IP addresses from Twitter. I am, though, happy I am among the people DOJ is casting their nets around because of my parliamentary immunity; I have a greater protection then many other users and can use that immunity to raise the issue of lack of rights for those that use social media.

((WN)) The same NYT article describes you as a WikiLeaks supporter; is this still the case? What attracts you to their ‘radical transparency’?

• Jonsdottir: I support the concept of WikiLeaks. While we don’t have a culture of protection for sources and whistleblowers we need sites like WikiLeaks. Plus, I think it is important to give WikiLeaks credit for raising awareness about in how bad shape freedom of information and expression is in our world and it is eroding at an alarming rate because of the fact that legal firms for corporations and corrupt politicians have understood the borderless nature of the legalities of the information flow online – we who feel it is important that people have access to information that should remain in the public domain need to step up our fight for those rights. WikiLeaks has played an important role in that context.I don’t support radical transparency – I understand that some things need to remain secret. It is the process of making things secret that needs to be both more transparent and in better consensus with nations.

((WN)) How do you think the Icelandic government would have reacted if it were tens of thousands of their diplomatic communications being leaked?

• Jonsdottir: I am not sure – A lot of our dirty laundry has been aired via the USA cables – our diplomatic communications with USA were leaked in those cables, so far they have not stirred much debate nor shock. It is unlikely for tens of thousands of cables to leak from Iceland since we dont have the same influence or size as the USA, nor do we have a military.

((WN)) Your ambassador in the US has spoken to the Obama administration. Can you discuss any feedback from that? Do you have your party’s, and government’s, backing in challenging the ordered Twitter data release?

• Jonsdottir: I have not had any feedback from that meeting, I did however receive a message from the DOJ via the USA ambassador in Iceland. The message stated three things: 1. I am free to travel to the USA. 2. If I would do so, I would not be a subject of involuntary interrogation. 3. I am not under criminal investigation. If this is indeed the reality I wonder why they are insisting on getting my personal details from Twitter. I want to stress that I understand the reasoning of trying to get to Assange through me, but I find it unacceptable since there is no foundation for criminal investigation against him. If WikiLeaks goes down, all the other media partners should go down at the same time. They all served similar roles. The way I see it is that WikiLeaks acted as the senior editor of material leaked to them. They could not by any means be considered a source. The source is the person that leaks the material to WikiLeaks. I am not sure if the media in our world understands how much is at stake for already shaky industry if WikiLeaks will carry on carrying the brunt of the attacks. I think it would be powerful if all the medias that have had access to WikiLeaks material would band together for their defence.

((WN)) Wikinews consulted a Belgian IT security expert who said it was most likely companies such as Facebook, Microsoft, and Google, would have complied with similar court orders *without advising the ‘targets*’. Does that disturb you?

• Jonsdottir: This does disturb me for various reasons. The most obvious is that my emails are hosted at google/gmail and my search profile. I dont have anything to hide but it is important to note that many of the people that interact with me as a MP via both facebook and my various email accounts don’t always realize that there is no protection for them if they do so via those channels. I often get sensitive personal letters sent to me at facebook and gmail. In general most people are not aware of how little rights they have as users of social media. It is those of uttermost importance that those sites will create the legal disclaimers and agreements that state the most obvious rights we lose when we sign up to their services.

((WN)) Has there been any backlash within Iceland against US-based internet services in light of this? Do you expect such, or any increase in anti-American sentiments?

• Jonsdottir: No, none what so ever. I dont think there is much anti-American sentiments in Iceland and I dont think this case will increase it. However I think it is important for everyone who does not live in the USA and uses social services to note that according to the ruling in my case, they dont have any protection of the 1st and 4th amendment, that only apply to USA citizens. Perhaps the legalities in relation to the borderless reality we live in online need to be upgraded in order for people to feel safe with using social media if it is hosted in the USA. Market tends to bend to simple rules.

((WN)) Does this make you more, or less, determined to see the IMMI succeed?

• Jonsdottir: More. People have to realize that if we dont have freedom of information online we won’t have it offline. We have to wake up to the fact that our rights to access information that should be in the public domain is eroding while at the same time our rights as citizens online have now been undermined and we are only seen as consumers with consumers rights and in some cases our rights are less than of a product. This development needs to change and change fast before it is too late.

The U.S. Government continues to have issues internationally as a result of material passed to WikiLeaks, and subsequently published.

Within the past week, Ecuador has effectively declared the U.S. ambassador Heather Hodges persona-non-grata over corruption allegations brought to light in leaked cables. Asking the veteran diplomat to leave “as soon as possible”, the country may become the third in South America with no ambassadorial presence. Both Venezuela and Bolivia have no resident U.S. ambassador due to the two left-wing administrations believing the ejected diplomats were working with the opposition.

The U.S. State Department has cautioned Ecuador that a failure to speedily normalise diplomatic relations may jeapordise ongoing trade talks.

The United Kingdom is expected to press the Obama administration over the continuing detention of 23-year-old Manning, who also holds UK citizenship. British lawmakers are to discuss his ongoing detention conditions before again approaching the U.S. with their concerns that his solitary confinement, and treatment therein, is not acceptable.

The 22 charges brought against Manning are currently on hold whilst his fitness to stand trial is assessed.
