• Solving “Link Discovery” Problem for Terahertz Data Networks

    When someone opens a laptop, a router can quickly locate it and connect it to the local Wi-Fi network. That ability is a basic element of any wireless network known as link discovery, and now a team of researchers has developed a means of doing it with terahertz radiation, the high-frequency waves that could one day make for ultra-fast wireless data transmission.

  • Artificial Intelligence Could Help Stem Tide of School Violence

    By leveraging the basics of artificial intelligence technology now used to predict risk for suicide or other mental health issues, researchers developed an AI system that analyzes linguistic patterns to predict a youth’s risk for committing acts of school violence.

  • The Deepfake iPhone Apps Are Here

    On Sunday, Lawfare’s Jacob Schulz, like many Americans, woke up to see that President Donald Trump had retweeted a misleading gif of his presumptive Democratic challenger, Joe Biden. Schultz notes that Trump’s dissemination of a deepfake video was met with alarm. David Frum, for example, noted the significance of the president’s retweet: “Instead of sharing deceptively edited video—as Trump and his allies have often done before—yesterday Trump for the first time shared a video that had been outrightly fabricated.” Schulz adds: “Soon, people will be able to use their iPhones not just to turn themselves into mildly convincing late-night comedians but to convincingly turn Joe Biden into whatever they want. When that happens, in the now-infamous words of Samantha Cole of Motherboard, ‘We are truly f****d.’”

  • German start-up in global demand with anti-virus escalators

    Tanja Nickel and Katharina Obladen were still in high school when they patented an idea to disinfect escalator handrails using UV light. Michelle Fitzpatrick writes (AFP / Barron’s) that a decade later, their small German start-up UVIS can barely keep up with orders from around the world for their coronavirus-killing escalators and coatings for supermarket trolleys and elevator buttons. “Everybody wants it done yesterday,” Obladen, 28, told AFP at the company’s workshop in central Cologne. “The pandemic has made businesses realise they need to invest in hygiene precautions for staff and customers. It’s gone from nice-to-have to must-have.” As Germany begins to relax some lockdown restrictions, the start-up’s five-person team has been inundated with requests from shops, offices and cafes eager to reopen to a public newly aware of the health risks lurking in shared spaces.

  • Israeli Researchers Say They Can Make Disinfectant from Tap Eater

    Researchers electrify water to produce hypo chloric acid at defined level of acidity; patented method has not been published in science journal or subject to peer review. Shoshana Solomon writes in the Times of Israel that researchers at Bar-Ilan University have developed what they say is a new way to make strong and environmentally friendly disinfectants to kill bacteria and viruses by using just tap water. The disinfectant materials were recently tested by researchers in the virology labs of Prof. Ronit Sarid of the Mina and Everard Goodman Faculty of Life Sciences at the university and at the Poriya Hospital in the north of Israel, and were “proven effective” in neutralizing microbes, fungus and corona-type viruses, Aurbach said in a phone interview.

  • France, Europe Mull Controversial Coronavirus Tracing Apps

    France’s parliament votes next week on plans to use a controversial tracing app to help fight the coronavirus, as the country eyes easing its lockdown next month. Lisa Bryant writes in VOA News that French Digital Affairs Minister Cedric O says the downloadable app would notify smartphone users when they cross people with COVID-19, helping authorities track and reduce the spread of the pandemic. In a video on the ruling party’s Facebook page, O said the so-called “Stop COVID” app will fully respect people’s liberties, and will be completely voluntary and anonymous. It also will be temporary — lasting only as long as the pandemic, he added. The government wants to launch the app on May 11, the date it has set to begin easing a two-month lockdown in the country. It initially announced a parliamentary debate on the technology, but that’s been changed to a vote, after major pushback from lawmakers.

  • NIST Tool Could Help Hospitals Repurpose Rooms for Disinfecting N95 Masks

    In response to the COVID-19 pandemic, hospitals across the United States are disinfecting N95 masks by placing them in repurposed rooms or shipping containers injected with a disinfectant known as vaporized hydrogen peroxide, or VHP. A new tool from the National Institute of Standards and Technology (NIST) can help hospitals and medical professionals determine which rooms should be used to disinfect N95 masks. The tool estimates the amount of VHP masks would receive and suggests that larger rooms containing fewer objects, with less-reactive surfaces and slower ventilation, maintain VHP concentration the best.   

  • Self-Powered X-Ray Detector Improves Imaging for Medicine, Security, Research

    A new X-ray detector prototype is on the brink of revolutionizing medical imaging, with dramatic reduction in radiation exposure and the associated health risks, while also boosting resolution in security scanners and research applications. 2-D perovskite thin films boost sensitivity 100-fold compared to conventional detectors, require no outside power source, and enable low-dose dental and medical images.

  • How Will the Pandemic Affect National Security Innovation

    The second week of March was an inflection point for many across the world. Rachel Olney writes that as a founder of a tech company with commercial and defense customers, she has concerns for the early-stage companies with defense applications. With the massive economic downturn came panicked investors trying to determine which companies in their portfolios would survive. “They reached out to learn how much cash we have, if we can do layoffs, and if we would ultimately survive,” she writes. “My experience was not unique.”

  • Israel Launches New “Contactless” Roadside CPVID-19 Testing Booths Which Have Zero Contact between Nurse and Patient

    Israel has launched a network of new ‘contactless’ roadside covid-19 testing booths which have zero contact between nurse and patient. The Daily Mail reports that the country has offered to share the design, which is relatively cheap and easy to produce, with other countries as part of the fight against the coronavirus pandemic. The booths, produced by healthcare companies together with civilian and military partners, provide an entirely sealed, sterile environment for the medic, and can be quickly disinfected between patients. Tests are carried out using two rubber gloves which are attached to the outer wall with airtight seals. Results are processed in a matter of hours and reported directly via the patient’s electronic health record.

  • Toward an Unhackable Quantum Internet

    A quantum internet could be used to send un-hackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss. Researchers have found a way to correct for signal loss.

  • Increasing Fire Protection through Virtual Reality

    Fire is one of the most dreaded anxieties in households worldwide. In 2018 Dutch insurance companies registered no less than 80,000 domestic fires. The most common cause is smoking, followed by technical malfunctions in appliances and cooking. Preventive measures can avoid many of the consequences and there is a lot to be gained.

  • The Coronavirus Contact Tracing App Won't Log Your Location, but It Will Reveal Who You Hang Out With

    The Australian federal government has announced plans to introduce a contact tracing mobile app to help curb COVID-19’s spread in Australia. Roba Abbas and Katina Michael write in The Conversation that rather than collecting location data directly from mobile operators, the proposed TraceTogether app will use Bluetooth technology to sense whether users who have voluntarily opted-in have come within nine metres of one another. Contact tracing apps generally store 14-21 days of interaction data between participating devices to help monitor the spread of a disease. The TraceTogether app has been available in Singapore since March 20, and its reception there may help shed light on how the new tech will fare in Australia.

  • Strengthening Mobile Device Email Security and Privacy

    Large and small organizations alike now rely heavily on mobile devices like smartphones or tablets to enable their workers, customers and management to connect and collaborate, even when some or all of them are working remotely. But device users may prioritize convenience over strong security, accidently share sensitive information with unintended audiences, or use their corporate- or government-owned devices in contexts in which sensitive business information should not be shared.

  • System to Locate Rescue Forces in Distress

    In the event of fires, earthquakes, or in other emergency situations, rescue forces are often called to free persons caught in buildings. These rescue missions are very risky: Dangers are difficult to assess in advance and the helpers themselves may suddenly need help. To support them as quickly as possible, researchers have developed a system to locate injured or buried rescue forces in buildings. For positioning, no GPS signal is needed.
