Researchers Say New Studies Confirm Cell Phone Hazards [23May11] - 0 views

  • a group of international researchers meeting in Istanbul, Turkey has released what they call “stunning proof” that confirms findings from the Council of Europe -- pulsed digital signals from cell phones disrupt DNA, impair brain function and lower sperm count. A meeting convened by Environmental Health Trust, with the Turkish cancer society, and Gazi University, revealed the new research that the scientists say shows damage to DNA, brain and sperm
  • Nesrin Seyhan, an advisor to the World Health Organization (WHO) and NATO and head of the Biophysics Department and Bioelectromagnetics Laboratory at Gazi University in Ankara, presented findings that he says confirm the warning that just four hours of exposure to cell phone radiation disrupts the ability of human brain cells to repair damaged genes. “We are deeply concerned about what this could mean for public health,” Seyhan said. Prof. Wilhelm Mosgoeller from the Medical University of Vienna, who has led European research teams, said he found that the cell waves induce DNA breaks. Despite industry claims to the contrary, he says DNA breaks are real.
  • Insect studies A research team at the University of Athens said insect studies have demonstrated that acute exposure to GSM (Global System for Mobile) signals brings about DNA fragmentation in insects’ ovarian cells, and consequently a large reduction in the reproductive capacity of the insects. Further studies, they said, demonstrated that long exposures induced cell death to the insects in the study. Other researchers said throughout a gestation period, exposure to radiation for just six minutes a day affects the bone formation of fetuses. The researchers also worry about the effect of cell phone use on children.

  • At higher frequencies, children absorb more energy from external radio frequency radiation than adults, because their tissue normally contains a larger number of ions and so has a higher conductivity. The researchers strongly suggest limiting cell phone and cordless phone use by young children and teenagers to the lowest possible level and urgently ban telecom companies from marketing to them. The researchers call their findings “thought-provoking” and say they have never been investigated in North America. “The evidence justifies precautionary measures to reduce the risks for everyone of us,” Wosgoeller said. The meeting was sponsored by Environmental Health Trust, The International Commission on Electromagnetic Safety, Gazi University and Athens University.

Researchers Uncover 'Massive Security Flaws' In Amazon Cloud [28Oct11] - 0 views

  • Amazon's cloud services are vulnerable to attack via a "massive security gap" that enables hackers to access user accounts and data, a team of German researchers has revealed.
  • Security researchers from Ruhr-University Bochum (RUB) found that Amazon (NSDQ:AMZN) Web Services was vulnerable to different methods of attack, including signature wrapping and cross site scripting, Those security holes have since been closed.
  • But similar security holes may still be open in other cloud infrastructure offerings, the RUB team found.
  • ...7 more annotations...
  • "Using different kinds of XML signature wrapping attacks, we succeeded in completely taking over the administrative rights of cloud customers," said RUB researcher Juraj Somorovsky in a statement. "This allowed us to create new instances in the victim's cloud, add or delete images."
  • The researchers suggested that many cloud offerings are vulnerable to signature wrapping attacks, due to a deviation between performance and security when dealing with Web services.
  • Along with cross scripting attacks, the researchers uncovered gaps in the AWS interface and in the Amazon online story through which executable script code could be smuggled, or open to cross-site scripting attacks. Through the attack, the RUB security team was able to access customer data.
  • "We had free access to all customer data, including authentication data, tokens, and even plain text passwords," said RUB researcher Mario Heiderich. "It's a chain reaction. A security gap in the complex Amazon shop always also directly causes a gap in the Amazon cloud."
  • Along with Amazon's public cloud offerings, the RUB security crew also found single wrapping attack and cross site scripting vulnerabilities in private cloud services, including open-source cloud play Eucalyptus Systems. Eucalyptus also immediately closed the security gap when notified by RUB researchers.
  • "A major challenge for cloud providers is ensuring the absolute security of the data entrusted to them, which should only be accessible by the clients themselves," said Prof. Dr. Jorg Schwenk.
  • Somorovsky added: "Therefore it is essential that we recognize the security gaps in cloud computing and avoid them on a permanent basis.

Researchers Find Stunning Evidence of Cell Phone Dangers [25May11] - 0 views

  • Researchers have reported evidence that cell phone radiation has a variety of alarming biological effects, which are sure to fuel concerns about whether or not phones impact human health. Scientists reportedly found that GSM signals fragmented insect DNA in ovarian cells, that a brief "mild electromagnetic field" affects bone formation in fetuses, and that cell phone-frequency radiation increased the permeability of the blood-brain barrier in young adult male rats.
  • These findings were reported in a press release issued by the Environmental Health Trust, which notes that the rat brains can be "used to correspond to the brains of human teenagers." "This work provides a warning signal to all of us," said Professor Wilhelm Mosgoeller from the Medical University of Vienna. "The evidence justifies precautionary measures to reduce the risks for everyone of us."
  • other research findings, while potentially interesting, appear to be in-vitro studies of isolated cells. Proving biological effects of radiation on cells is useful in determining the ways radiation might impact humans in the real world, but it does not directly prove much beyond the experimental criteria.
  • ...2 more annotations...
  • It's unclear whether the research has been published in peer-reviewed journals: if it has not, additional salt must be added to interpreting the findings.
  • Substantial research into potential health effects of cell phone use on humans has been conducted, and there is no conclusive proof of danger. Some studies have found possible links between phone use and cancer, but the findings are weakened by limitations that make results difficult to interpret. Many studies have found no effects at all. Some, highlighting the difficulties of studying statistically rare events, have even found that phones reduce cancer risk. A recent study published in the Journal of the American Medical Association found a link between cell phone use and increased glucose metabolism in the brain, which, like other studies finding biological effects, may or may not imply a health effect.
  •  
    Bottom line is that nobody knows if cell phones are bad for us.

Virtual outdoors to aid patient recovery, reduce pain levels [25May11] - 0 views

  • University scientists are seeking to take virtual reality to a new level – with a view to helping sick people who cannot get access to the outside world. The researchers in Birmingham plan their new worlds to be “sensorily rich”.They are using large screen TVs, video projectors and head mounted displays to create virtual versions of soothing rural and coastal scenes. The initial development is re-creating a stretch of the coastline of south Devon and an area within Dartmoor National Park.The developers say there is research evidence that exposure to greenery, such as trees, can improve patient recovery and reduce pain levels. Tests on volunteers are due to start later this summer. Birmingham University has become involved because its local hospital provides specialist defence medical facilities and has a large number of trauma victims.Developer Professor Bob Stone, a multimedia specialist, said: “This technology could be made available to anyone who, for whatever reason, is in hospital, bed-bound or cannot get outside.  They will be able to get the benefits of the countryside and seaside by viewing the virtual scenario on screen. Patients will be free to choose areas that they want to spend time in; they can take a walk along coastal footpaths, sit on a beach, listen to the waves and birdsong, watch the sun go down and – in due course – even experience the smells of the land-and seascapes almost as if they were experiencing the outdoors for real.”

Unpacking Badges for Lifelong Learning [25Sep11] - 0 views

  • Author: Sheryl Grant
  • Is there some core definition or badge-ness to explain what makes badges unique?
  • If badges are like degrees, diplomas, grades, or currency -- which many of us have collected and displayed and benefited from -- what's wrong with them? Why are badges worse or better? If badges are visual signs of rank, reputation, membership, and identity, and are just another way to show affiliation, why are they different than, say, titles, clothing, hair, language, accents, bumper stickers, friends, or an alma mater?  
  • ...6 more annotations...
  • Because badges hinge on motivation. Most of the energy in the badges conversation seems to have roots in the different ways people think about motivation, and more specifically about motivation and learning. What motivates learners to learn? What de-motivates them? 
  • Where's the line between motivating a learner and manipulating them?
  • For me, the most interesting intersection of the Badges for Lifelong Learning conversation is where learning theories overlap with research into virtual communities, new collectives, commons-based peer production -- whatever you want to call what we do online. A good deal of Internet research is about participation and motivation. If anything connects the badges community, it's seems to be the belief that more participation is better.
  • The communities of practice research links new collectives like Wikipedia with learning and identity, and authenticity is thought to affect people's motivation to learn and participate and reach goals.
  • There's this obscure ID Compensation theory that isn't even on Wikipedia! yet!
  • What if badges are just one more way to represent feedback? What if they're the best, most versatile way to provide feedback, whether that feedback is many-to-one, one-to-one, or many-to-many?

How Facial Recognition Technology Can Be Used To Get Your Social Security Number [01Aug11] - 0 views

  • Those freaked out by facial recognition technology have fresh fodder: a study from Carnegie Mellon University in which researchers were able to predict people’s social security numbers after taking a photo of them with a cheap webcam.
  • For those participants who had date of birth and city publicly available on their account, the researchers could predict a social security number (based on the work from their 2009 study). The researchers sent a follow-up survey to their student participants asking them whether the first five digits of the social security number their algorithm predicted was correct. One problem with this part of the study was that “60% of the CMU students were foreign and don’t have social security numbers,” said Acquisti. Though researchers were still able to tell them all about their interests and favorite movies based on what they got from their Facebook profile pages.

Social network NFC tag scans increasing 22% per month [13Sep11] - 0 views

  • NFC tag scans for connection sharing, social networking and marketing are increasing at a rate of 22 per cent per month, according to new research carried out by Kimtag. Kimtag, a UK based connection hub, analysed the visits to 10,000 selected Kimtag connection pages over a six month period ending in August 2011. The company compared QR Code, NFC tag, direct and referral hits from visitors around the world. 
  • During the research, Kimtag regarded a successful visit as a user reaching and fully downloading a Kimtag connection page via an address assigned specifically for NFC tags and then subsequently visiting a connection such as a social network or website.  The research revealed that the number NFC tag scans grew by an average 22 per cent month on month. Over the whole six month period, NFC scans increased by over 170 per cent.
  • Phil Coote, Kimtag’s CEO, commented, "The research illustrates that while a lot of the current focus within the NFC industry has been on payment systems, the use of NFC to empower the new ‘internet of things’ is likely to play an equally important role in it’s growth."

How Long Before NFC-Based Mobile Payments are a Widespread Reality? [28Jun11] - 0 views

  • A 2009 analysis from Juniper Research (News –Alert) of the $110bn NFC opportunity forecasted that one in every six mobile subscribers (about 17 percent) globally will have an NFC enabled device by 2014. Adoption was expected to be highest in the Far East,with use very limited outside of that region.
  • By 2014,Juniper now predicts that North America will account for just under half of NFC smartphones,followed by Western Europe.
  • The latest forecast from Juniper Research suggests that at least 20 percent of smartphones will support NFC by 2014,about 300 million phones.
  • ...2 more annotations...
  • IHS (News –Alert) iSuppli,for its part,now predicts 93.2 million NFC-equipped cellphones will ship worldwide in 2011,up from its December 2010 forecast of 79.8 million. In 2014,411.8 million NFC cell phones are forecast to ship,compared to 220.1 million in the previous prediction.Shipments then will rise to 544.7 million in 2015,says iSuppli,so that 30.5 percent of all cell phones shipped that year would come with NFC capabilities.
  • Eric Schmidt (News –Alert),Google’s executive chairman,believes that a third of point of sale terminals in retail stores and restaurants will be upgraded to allow NFC payments within the next year,the Financial Times reported.

Teenagers would rather lose TV than internet or mobile - survey [25Oct11] - 0 views

  • Young British teenagers would be less worried at being deprived of television than losing access to the internet or their mobile phones, as attachment to the medium slides among the young, according to new research from Ofcom.
  • On average, they watch 17 hours 37 minutes per week, up from 15 hours 37 minutes in 2007.Internet use has also become pervasive, with 95% of 12- to 15-year-olds having internet access at home through a computer. But the research by the communications watchdog also points to a "digital divide", in which only 80% of children in lower socioeconomic groups have access to the internet at home, compared to 98% in the richest ones.
  • The annual survey was carried out in spring with 1,717 in-home interviews, and focused on attitudes to communications technology by parents and children. It found that 28% of children aged 12 to 15 said they would most miss their mobile, and 25% would most miss the internet if deprived of them – compared to only 18% citing television. A year ago mobile was the most desired, while TV was level-pegging with the internet at 24%.

  • "The research also shows that parents and children are increasingly aware of how to be safe when using the internet," said Ofcom's Richards. "But risks do remain. Better understanding – amongst parents as well as their children – is the key to helping people to manage content and communications, enabling them to enjoy the benefits of media use while protecting themselves from the potential risks."

Debenhams explores mobile payments | News | New Media Age [25Nov11] - 0 views

  • Debenhams is in talks to introduce till payments through mobile phones as research finds that handsets are set to become ubiquitous as a way of paying for goods in five years’ time.
  • The high street retailer said it is exploring ways to let customers use their mobiles to pay for goods in-store.
  • Harriet Williams, Debenhams’ head of digital, said, ”It is something we are looking at and talking to partners about. When we’ve done research, we’ve seen that it’s something particularly younger customers are more interested in.”
  • ...10 more annotations...
  • Williams said the department store chain would “love” to run a trial next year if all the participants needed to make mobile payments work – such as the banks and mobile operators – come together.
  • Research by PayPal said that 2016 will be the year when UK shoppers will use their mobiles to pay for their shopping, increasingly replacing cash and cards.
  • Robin Terrell, House of Fraser executive director of multi-channel and international, said payment through the mobile phone will “absolutely” be introduced in the future.
  • However, retailers have voiced their concerns over the difficulties in ensuring all the various players work together on NFC technology.
  • “As a customer, I am not going to have a different wallet for each financial institution, network and handset I have,” said Terrell. “Equally, the financial institutions will need to work together to raise the current £15 limit on NFC contactless payments. None of these issues are insurmountable, however, and the overall direction of travel is clear.”
  • Just this week Starbucks said that it is launching the high street’s first iPhone mobile app payment system after growing impatient with the rate of development of NFC technology
  • The coffee chain said it “did not want to wait” for the development of NFC and for it to become mainstream. Instead, it has developed its own mobile payment system using iPhone apps because so few handsets are currently NFC capable.
  • French Connection said mobile payment was not on its agenda just yet but it could see the method being taken up in the future.
  • Jennifer Roebuck, French Connection’s digital director, said, “There’s no reason why in five years you can’t swipe your mobile to pay for products. It’s too early days for us [but] it is logical, everyone uses a mobile for everything, such as shopping with Ocado. It’s becoming a little mini system to make payments.”
  • David Smith, IMRG chief marketing and communications officer, said, “The use of smartphones is going up and more technology that goes into them so the compatibility is not beyond it. But consumer trust and how quickly retailers have a system that’s foolproof are the biggest factors. It will inevitably come but how big it will be remains to be seen.”

The Internet of Things: Toolbox to help objects communicating via the Net - 0 views

  • Tools for collaboration The Internet of Things will introduce new smart objects to our homes. One challenge is to find effective solutions to enable different products to work together. Currently no standardised tools or distribution platforms exist in this area
  • A group of Norwegian researchers have been addressing this issue. In the research project Infrastructure for Integrated Services (ISIS) they have created a platform for developing and distributing applications for the Internet of Things. The platform encompasses a programming tool for developers, called Arctis and the website ISIS Store for downloading applications. The project has received funding from the Research Council of Norway's Large-scale Programme VERDIKT
  • "In a 'smart' everyday life objects and applications often need to be connected to several different communication services, sensors and other components. At the same time they need to respond quickly to changes and the actions of users. This requires very good control over concurrence in the system, which can be difficult to achieve with normal programming," he explains. Dr Kraemer believes that the tool will make it easier to create new applications, adapt them to existing applications and update software as necessary.

Study: Someday our bodies could 'talk' to gadgets - Tech News and Analysis [23Sep11] - 0 views

  • UW researchers say this new type of transistor could one day understand or even control body functions.
  • Materials scientists are looking at these proton-based microscopic transistors for future advances in prosthetics and biological sensing.
  • In the body, protons activate “on” and “off” switches and are key players in biological energy transfer. Ions open and close channels in the cell membrane to pump things in and out of the cell. Animals, including humans, use ions to flex their muscles and transmit brain signals. A machine that was compatible with a living system in this way could, in the short term, monitor such processes. Someday it could generate proton currents to control certain functions directly.
  • ...4 more annotations...
  • A first step toward this type of control is a transistor that can send pulses of proton current. The prototype device is a field-effect transistor, a basic type of transistor that includes a gate, a drain and a source terminal for the current. The UW prototype is the first such device to use protons.
  • Because their device’s proton current can be switched on and off, it can act as its own kind of electronic current, according to Marco Rolandi, a UW assistant professor of materials science and engineering. The transistor itself is “a twentieth the width of a human hair,” or about 5 microns wide. It is made of a compound, chitosan, found in both crab shells and squid pen (the structure inside a squid’s body that muscles attach to).
  • The first applications of this research will come some time “in the next decade or so,” and will be aimed at direct sensing of cells in a lab, researchers say
  • But further out they could be implanted directly in living organisms to monitor or control bodily processes.
