• Any single hair from the human body can be used for identification

    Any single hair from anywhere on the human body can be used to identify a person. This conclusion is one of the key findings from a nearly year-long study by a team of researchers. The study could provide an important new avenue of evidence for law enforcement authorities in sexual assault cases.

  • Rectifying a wrong nuclear fuel decision

    In the old days, new members of Congress knew they had much to learn. They would defer to veteran lawmakers before sponsoring legislation. But in the Twitter era, the newly elected are instant experts. That is how Washington on 12 June witnessed the remarkable phenomenon of freshman Rep. Elaine Luria (D-Norfolk), successfully spearheading an amendment that may help Islamist radicals get nuclear weapons. The issue is whether the U.S. Navy should explore modifying the reactor fuel in its nuclear-powered vessels — as France already has done — to reduce the risk of nuclear material falling into the hands of terrorists such as al-Qaida or rogue states such as Iran. Luria says no. Alan J. Kuperman writes in the Pilot Online that more seasoned legislators have started to rectify the situation by passing a spending bill on 19 June that includes the funding for naval fuel research. They will have the chance to fully reverse Luria in July on the House floor by restoring the authorization. Doing so would not only promote U.S. national security but teach an important lesson that enthusiasm is no substitute for experience.

  • Deepfake detection algorithms will never be enough

    You may have seen news stories last week about researchers developing tools that can detect deepfakes with greater than 90 percent accuracy. It’s comforting to think that with research like this, the harm caused by AI-generated fakes will be limited. Simply run your content through a deepfake detector and bang, the misinformation is gone!  James Vincent writers in The Verge that software that can spot AI-manipulated videos, however, will only ever provide a partial fix to this problem, say experts. As with computer viruses or biological weapons, the threat from deepfakes is now a permanent feature on the landscape. And although it’s arguable whether or not deepfakes are a huge danger from a political perspective, they’re certainly damaging the lives of women here and now through the spread of fake nudes and pornography.

  • The history of cellular network security doesn’t bode well for 5G

    There’s been quite a bit of media hype about the improvements 5G is set to supposedly bring to users, many of which are no more than telecom talking points. One aspect of the conversation that’s especially important to get right is whether or not 5G will bring much-needed security fixes to cell networks. Unfortunately, we will still need to be concerned about these issues—and more—in 5G.

  • Deepfakes: Forensic techniques to identify tampered videos

    Computer scientists have developed a method that performs with 96 percent accuracy in identifying deepfakes when evaluated on large scale deepfake dataset.

  • AI helps protect emergency personnel in hazardous environments

    Whether it’s at rescue and firefighting operations or deep-sea inspections, mobile robots finding their way around unknown situations with the help of artificial intelligence (AI) can effectively support people in carrying out activities in hazardous environments.

  • Geoengineer the planet? More scientists now say it must be an option

    Once seen as spooky sci-fi, geoengineering to halt runaway climate change is now being looked at with growing urgency. A spate of dire scientific warnings that the world community can no longer delay major cuts in carbon emissions, coupled with a recent surge in atmospheric concentrations of CO2, has left a growing number of scientists saying that it’s time to give the controversial technologies a serious look. Fred Pearce writes in Yale Environment 360 that among the technologies being considered are a range of efforts to restrict solar radiation from reaching the lower atmosphere, including spraying aerosols of sulphate particles into the stratosphere, and refreezing rapidly warming parts of the polar regions by deploying tall ships to pump salt particles from the ocean into polar clouds to make them brighter.

  • Identifying a fake picture online is harder than you might think

    Research has shown that manipulated images can distort viewers’ memory and even influence their decision-making. So the harm that can be done by fake images is real and significant. Our findings suggest that to reduce the potential harm of fake images, the most effective strategy is to offer more people experiences with online media and digital image editing – including by investing in education. Then they’ll know more about how to evaluate online images and be less likely to fall for a fake.

  • International community unprepared to deal with catastrophic biological event

    The risks of a global catastrophic biological event are growing, intensified by an increasingly interconnected world, terrorist and state interest in weapons of mass destruction, global political instability, and rapid advances in biotechnology. International leaders and organizations today are unprepared to react with the kind of effective, coordinated response needed to investigate and identify the pathogen, prevent the spread of disease, and, most importantly, save lives.

  • “Vaccinating” algorithms against attacks on machine learning

    Algorithms “learn” from the data they are trained on to create a machine learning model that can perform a given task effectively without needing specific instructions, such as making predictions or accurately classifying images and emails. Researchers have developed a world-first set of techniques to effectively “vaccinate” algorithms against adversarial attacks, a significant advancement in machine learning research.

  • Mass surveillance is coming to a city near you

    The tech entrepreneur Ross McNutt wants to spend three years recording outdoor human movements in a major U.S. city, KMOX news radio reports. Conor Friedersdorf writes in The Atlantic that if that sounds too dystopian to be real, you’re behind the times. McNutt, who runs Persistent Surveillance Systems, was inspired by his stint in the Air Force tracking Iraqi insurgents. He tested mass-surveillance technology over Compton, California, in 2012. In 2016, the company flew over Baltimore, feeding information to police for months (without telling city leaders or residents) while demonstrating how the technology works to the FBI and Secret Service.

  • NIST updates to help defend sensitive information from cyberattack

    An update to one of the National Institute of Standards and Technology’s (NIST) information security documents offers strategies to help protect sensitive information that is stored in computers supporting critical government programs and high value assets. The new companion publication offers enhanced security for information stored in critical programs and assets.

  • Shoe scanner may improve airport security

    The types of shoes you wear when flying matter. And not just shoe types. Size, material, soles and heels are also very important. Why? Shoes can become dangerous vehicles for terrorists’ plots. DHS wants to prevent future incidents, and this is why S&T is working on a millimeter wave technology for screening shoes as part of the larger Screening at Speed Program.

  • New technology to measures WMD threat exposures

    Researchers are looking to find molecular signatures in blood that identify previous exposures and time of exposure to materials that could be associated with weapons of mass destruction (including infectious agents, chemicals, and radiation). The epigenome is biology’s record keeper, and Epigenetic technology will provide a new tool in the fight against the proliferation of weapons of mass destruction.

  • Optimizing use of future wave electricity generators during disaster

    When hurricanes strike, loss of electricity ranks as one of the top concerns for relief workers. Blackouts lasting a week or more can hamper recovery efforts, shutter hospitals, threaten public health and disrupt transportation. The months-long effort to restore power to Puerto Rico following the 2017 hurricane season has led to renewed interest in finding innovative ways to get affected power grids back online. Researchers look to develop a strategy for how floating devices that harness the energy of the oceans’ waves might be able to provide this much needed aid.
