• 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.

  • Study Calls into Question Use of Malaria Drug for COVID-19

    By Chris Dall

    A retrospective study of patients with COVID-19 found no evidence that the anti-malaria drug hydroxychloroquine, either with or without the antibiotic azithromycin, reduced mortality or the need for mechanical ventilation. Researchers also found that hydroxychloroquine alone was associated with increased mortality. Early excitement about the combination was based on a small French study, and President Donald Trump soon began touting the combination as a potential “game changer,” but the findings from the study, which is the largest to date to report on outcomes from treating COVID-19 patients with the anti-malaria drug and uses a database that has been used for many different studies, suggest that the hydroxychloroquine/azithromycin combination may not be as promising for treating COVID-19 as some have hoped. 

  • 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.   

  • The Problem of Modeling

    The lessons starting to emerge from the coronavirus crisis are predominantly not epidemiological but highly general aspects of public policy, Paul Collier writes: the over-reliance on expert modelling and the mismanagement of public services. “The current epidemic is a classic application of what economists call ‘radical uncertainty’: in a world that has inevitably become too complex to be adequately captured in models, a world of both ‘known unknowns’ and ‘unknown unknowns,’ the most sensible response to the question ‘what should we do?’ is ‘I don’t know’,” he argues.

  • Creating Virtual Cyber Defense Tool

    Researchers are helping protect the country’s most secretly held assets through a partnership that’s creating state-of-the-art, virtual cyberattack defenses. The researchers have customized an existing MSU-designed Netmapper computer program to develop next-generation cyber learning and training software that can scan and map the military’s complex computer network infrastructures.

  • Coronavirus Pandemic Is Paving the Way for an Increase in Superbugs

    By Ronan McCarthy

    The heroic efforts of researchers and healthcare professionals globally will eventually help us gain control of the coronavirus pandemic and there will be a decrease in the rate of new infections. The focus is still rightly on the damage this pandemic is causing, the devastating loss of life and the impact on businesses and livelihoods. But we also need to look at other prevalent crises that are affecting our healthcare systems and anticipate the impact that the COVID-19 pandemic will have on them. One of the greatest threats to healthcare systems, around the world, is antibiotic resistance. The lack of effective antibiotics and the emergence of bacteria that are resistant to the drugs we have has resulted in the antibiotic resistance crisis.

  • 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.

  • Improving Accuracy of Storm Surge Analysis

    Accurately predicting how many people are at risk due to sea level rise and storm surges has always challenged scientists, but a new method is improving models that account for the impact of these natural occurrences. A new model developed by international team of scientists can be used to better understand and prepare for the impacts of climate change.

  • Coronavirus: Could the Pandemic Be Controlled Using Existing Vaccines Like MMR or BCG?

    The race is on to develop a vaccine that can protect us from the COVID-19 pandemic. An impressive 115 vaccine candidates are currently being investigated, but it is still many months before a vaccine might be approved. Sarah L Caddy writes in The Conversation that we already have hundreds of licensed vaccines for over 25 different viruses and bacteria that infect humans. We can protect ourselves against infections ranging from cholera to rabies. The common aim of all vaccines is to induce an immune response that prevents future disease. Is it possible that one of these existing vaccines could also induce protection against SARS-CoV-2, the virus causing COVID-19? Repurposing drugs is a popular strategy for treating COVID-19, as exemplified by the many trials using the Ebola drug remdesivir, or the antimalarial drug hydroxychloroquine. If an already-approved vaccine could reduce the severity of COVID-19, this would be really good news. The BCG vaccine has received recent attention for being a widely used vaccine that may help control COVID-19. A handful of studies identified an interesting association between the severity of COVID-19 in a country and how many of the population were vaccinated with BCG. The BCG vaccine apparently reduces the damage caused by COVID-19.

  • What the Pandemic Teaches Us about Nursing Home Care

    Nested in communities across the US, nursing homes serve as a societal safety net. Nursing homes provide essential care to individuals unable to live in the community. Roughly 1.3 million residents live in nursing homes receiving assistance with daily activities of living such as meals, dressing, and socialization. Additionally, more than 3 million older adults are discharged annually to nursing homes following a hospital stay to receive rehabilitative services like physical therapy and skilled nursing care. The University of Pennsylvania says that more than 2,000 nursing homes in the US have reported Covid-19 cases within their facilities, often accompanied by heart-wrenching rates of death. Combatting the avalanche of death posed by the novel coronavirus in nursing homes requires concerted effort to align several conflicting priorities that have afflicted nursing homes for years. Covid-19 puts into full view the regulatory structures and payment models that jeopardize care for long term care residents and those receiving post-acute care.

  • The Next Pandemic Might Not Be Natural

    Germs have killed more people than all the wars in history, and people have been trying to make use of them throughout all those wars. In the U.S., we have seen small-scale bioterrorist attacks – the Rajneeshee poisoning of restaurants in 1986 and the Amerithrax letters that were mailed in 2001. Still, the years running up to this current coronavirus pandemic not only saw the gutting of U.S. national health institutions but also a cultural groundswell of science denial in the anti-vaccination movement. Today the United States in particular is paying for that denial in livelihoods and lives. The warnings were clear. If 9/11 was a “failure of imagination,” then history will no doubt judge the Trump administration’s response to COVID-19 as a failure of courage, compassion, and, most of all, competence.

  • 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.

  • Abbott Launches COVID-19 Antibody Test

    Abbott has launched its third test for coronavirus (COVID-19) and will start shipping it in the U.S. The test is a serology test – also called an antibody test – which could be a critical next step in battling this virus. Abbott says its test helps to detect the IgG antibody to SARS-CoV-2. An antibody is a protein that the body produces in the late stages of infection and may remain for up to months and possibly years after a person has recovered. Detecting these IgG antibodies will help determine if a person was previously infected with the virus that causes COVID-19. The new antibody test is to be used on Abbott’s ARCHITECT i1000SR and i2000SR laboratory instruments, which can run up to 100-200 tests an hour.

  • Toward an Unhackable Quantum Internet

    By Leah Burrows

    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.
