    One whole endogenous retrovirus genome -- and bits of 17 others -- were spotted in a study of 2,500 human genomes... Nineteen new pieces of DNA -- left by viruses that first infected our ancestors hundreds of thousands of years ago -- have just been found, lurking between our own genes. And one stretch of newfound DNA, found in about 50 of the 2,500 people studied, contains an intact, full genetic recipe for an entire virus, say the scientists who published their findings today in the Proceedings of the National Academy of Sciences. Whether or not it can replicate, or...

    US researchers claim to have developed a single test that is able to identify past exposure to every known human virus infection, using a drop of blood.The technique decodes the infection history imprinted in our immune response. The scientists hope that the test will eventually provide important insight into how viruses contribute to development of a range of diseases. The work was published in the journal Science. During a virus infection, your immune system generates antibodies designed to fight the virus. Each antibody recognises a tiny fragment of the virus and their interaction is very specific - they fit like...

    Plan for lethal-virus laboratories leaves Smalltown USA in uproar By Andrew Gumbel in Los Angeles 29 June 2003 A network of high-security laboratories for storing and investigating some of the most lethal viruses known to mankind is being built across the US, leaving communities in uproar. They not only fear the risk of the viruses escaping, but also contend that the programme, part of the $6bn (£3.5bn) Project BioShield, is a stunning case of overkill. For none of the germs to be studied is related to bioweaponry. In the tiny town of Hamilton, Montana, campaigners worry that they will become...

    We have the earth-shattering technology in our hands—but even its inventors worry about its awesome power to alter our genetic future. “We have within our grasp the technology to change evolution. This could change the course of biological life.” — Paul Berg, Nobel Laureate and a pioneer of genetic engineeringIn 2012, scientists in the U.S. and Sweden invented a technology as potentially life-altering as splitting the atom. One that you haven’t heard of—yet—called “CRISPR-Cas9”. This innovation with the cumbrous name allows biologists to edit DNA almost as easily as cutting and pasting words and letters on a laptop.Scientists say...

    “Adobe is scurrying to patch the third Flash zero-day of the year, with criminal hackers already using a previously unknown and unpatched vulnerability to launch attacks against thousands of web denizens, security researchers warned today,” Thomas Fox-Brewster reports for Forbes. “Those attacks hit visitors to popular video sharing site Dailymotion, with other sites thought to be affected as the infections were launched via advertisements that will likely be resident on many other web pages.” “Visitors to any affected site would have been redirected to an attacker-controlled page where an exploit kit would attempt to compromise the target system by targeting...

    Washington University School of Medicine researchers have found that those patients who suffer from inflammatory bowel diseases also had a greater variety of viruses contained within their digestive systems than they found in the bowels of health volunteers. This, they believe, suggests that viruses somehow play a role in the development of this condition. ... “This is the tip of the iceberg. A significant portion of the viral DNA we identified in these patients is unfamiliar to us—it comes from newly identified viruses we don’t know much about,” explains senior study author Herbert W. Virgin. “We have a great deal...

    Ebola, Marburg viruses edit genetic material during infectionFiloviruses like Ebola "edit" genetic material as they invade their hosts, according to a study published this week in mBio®, the online open-access journal of the American Society for Microbiology. The work, by researchers at the Icahn School of Medicine at Mount Sinai, the Galveston National Laboratory, and the J. Craig Venter Institute, could lead to a better understanding of these viruses, paving the way for new treatments down the road. Using a laboratory technique called deep sequencing, investigators set out to investigate filovirus replication and transcription, processes involved in the virus...

    A team of UCLA-led researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others designated "priority pathogens" for national biosecurity purposes by the National Institute of Allergy and Infectious Disease. In a study published in the January issue of the journal Immunity, the researchers describe the novel antiviral property of the protein, cholesterol-25-hydroxylase (CH25H), an enzyme that converts cholesterol to an oxysterol called 25-hydroxycholesterol (25HC), which can permeate a cell's wall and block a virus from getting in....
  • 'Tinba' Bank Trojan Burrows into Browsers to Steal Logins

    Researchers have spotted a new banking Trojan subbed 'Tinba' that appears to have hit on a simple tactic for evading security - be as small as possible. An astonishing 20KB in size, Tinba ('Tiny Banker') retains enough sophistication to match almost anything that can be done by much larger malware types. Its main purpose is to burrow into browsers in order to steal logins, but it can also use 'obfuscated' (i.e disguised) web injection and man-in-the-browser to attempt to finesse two-factor web authentication systems. A particularly interesting feature is the way it tries to evade resident security, injecting itself into...

    Avira has stirred up some controversy among users after deciding to display ads for a third-party registry cleaner within the free version of its antivirus product. Avira AntiVir Personal, the free solution offered by the German security vendor, is one of the most popular anti-malware products on the market today and has over 100 million users. It seems that Avira recently partnered up with Uniblue, the owners of ProcessLibrary.com, a database of information about Windows processes, and creators of several software products. The partnership between the two companies requires Avira to display ads for Uniblue RegistryBooster within AntiVir Personal. These...

    First of the parasitic parasites to be discovered in a natural environment points to hidden diversity. A genomic survey of the microbial life in an Antarctic lake has revealed a new virophage — a virus that attacks viruses. The discovery suggests that these life forms are more common, and have a larger role in the environment, than was once thought. An Australian research team found the virophage while surveying the extremely salty Organic Lake in eastern Antarctica. While sequencing the collective genome of microbes living in the surface waters, they discovered the virus, which they dubbed the Organic Lake Virophage...

    A team at Oxford University has had success testing a vaccine that can neuter any strain of flu virus. Photograph: Science Photo Library The treatment ... targets a different part of the flu virus to traditional vaccines, meaning it does not need to be expensively reformulated every year to match the most prevalent virus that is circulating the world. Developed by a team led by Dr Sarah Gilbert at Oxford's Jenner Institute, the vaccine targets proteins inside the flu virus that are common across all strains, instead of those that sit on the virus's external coat, which are liable...

    Enlarge Image Buried gem. Researchers have uncovered "fossil virus" inside the zebra finch genome. Credit: Peripitus/Wikimedia The hepatitis B virus and its ilk have been around for a long, long time. A newly uncovered "viral fossil" buried deep in the genome of the zebra finch indicates that the hepatitis B family of viruses—known as hepadnaviruses—originated at least 19 million years ago. Together with recent findings on other viruses, the work suggests that all viruses may be much older than thought. No one knows exactly where or when viruses originated. They don't leave fossils, so scientists have begun scouring the...

    Has anyone in the last week gotten a computer virus from Antispyware Soft? It was a real bear to get rid of. I picked it up over the past weekend, and wondered if I could have possibly gotten it from FR or perhaps the alternate FR site when FR was inoperative sometime over the weekend. When I typed Start/run/msconfig and went to the start menu, there was an item ending in tssd.exe which is the virus. Also in start/run/regedit, there was AV Soft and AV Suite. After many times, restarting and unchecking tssd.exe, and running Microsoft Security Essentials, I believe...
