• Researchers Release COVID-19 Symptom Tracker App

    A consortium of scientists with expertise in big data research and epidemiology recently developed a COVID Symptom Tracker app aimed at rapidly collecting information to aid in the response to the ongoing COVID-19 pandemic. As reported in the journal Science, early use of the app by more than 2.5 million people in the U.S. and the U.K has generated valuable data about COVID-19 for physicians, scientists and public officials to better fight the viral outbreak.

  • Monitoring COVID-19 from Hospital to Home: First Wearable Device Continuously Tracks Key Symptoms

    The more we learn about the novel coronavirus (COVID-19), the more unknowns seem to arise. These ever-emerging mysteries highlight the desperate need for more data to help researchers and physicians better understand — and treat — the extremely contagious and deadly disease. Northwestern University says that Researchers at Northwestern and Shirley Ryan AbilityLab in Chicago have developed a novel wearable device and are creating a set of data algorithms specifically tailored to catch early signs and symptoms associated with COVID-19 and to monitor patients as the illness progresses. 

  • All Disease Models Are “Wrong,” but Scientists Are Working to Fix That

    An international team of researchers has developed a new mathematical tool that could help scientists to deliver more accurate predictions of how diseases, including COVID-19, spread through towns and cities around the world. Rebecca Morrison, an assistant professor of computer science at CU Boulder, led the research. CU says that for years, she has run a repair shop of sorts for mathematical models—those strings of equations and assumptions that scientists use to better understand the world around them, from the trajectory of climate change to how chemicals burn up in an explosion.  As Morrison put it, “My work starts when models start to fail.”

  • Changes in Snowmelt Threaten Farmers in Western U.S.

    Farmers in parts of the western United States who rely on snowmelt to help irrigate their crops will be among the hardest hit in the world by climate change, a new study reveals. The study pinpointed basins globally most at risk of not having enough water available at the right times for irrigation because of changes in snowmelt patterns. Two of those high-risk areas are the San Joaquin and Colorado river basins in the western United States.

  • U.S. Allows Use of Remdesivir, 1st Drug Shown to Help Virus Recovery

    U.S. regulators on Friday allowed emergency use of remdesivir, the first drug that appears to help some COVID-19 patients recover faster, a milestone in the global search for effective therapies against the coronavirus. Matthew Perrone and Marilynn Marchione write for AP that the Food and Drug Administration cleared Gilead Science’s intravenous drug for hospitalized patients with “severe disease,” such as those experiencing breathing problems requiring supplemental oxygen or ventilators. The FDA acted after preliminary results from a government-sponsored study showed that the drug, remdesivir, shortened the time to recovery by 31%, or about four days on average, for hospitalized COVID-19 patients. Those given the drug were able to leave the hospital in 11 days on average vs. 15 days for the comparison group. The drug may also help avert deaths, but that effect is not yet large enough for scientists to know for sure. The National Institutes of Health’s Dr. Anthony Fauci said Wednesday the drug would become a new standard of care for severely ill COVID-19 patients. Remdesivir, which blocks an enzyme the virus uses to copy its genetic material, has not been tested on people with milder illness. The FDA previously allowed narrow use of a malaria drug, hydroxychloroquine, for hospitalized patients who were unable to take part in ongoing studies of the medication. President Trump touted the drug as a “game changer” and repeatedly promoted it as a possible COVID-19 treatment, but no large high-quality studies have shown the drug works for that and it has significant safety concerns.

  • Hydroxychloroquine for Treatment of COVID-19 Linked to Increased Risk of Cardiac Arrhythmias

    In a brief report published today in JAMA Cardiology, a team of pharmacists and clinicians at Beth Israel Deaconess Medical Center (BIDMC) found evidence suggesting that patients who received hydroxychloroquine for COVID-19 were at increased risk of electrical changes to the heart and cardiac arrhythmias. The combination of hydroxychloroquine with azithromycin was linked to even greater changes compared to hydroxychloroquine alone. Hydroxychloroquine and azithromycin each can cause an electrical disturbance in the heart known as a QTc prolongation, indicated by a longer space between specific peaks on an electrocardiogram. QTc prolongation denotes that the heart muscle is taking milliseconds longer than normal to recharge between beats. The researchers note that the delay can cause cardiac arrhythmias, which in turn increases the likelihood of cardiac arrest, stroke, or death. “While hydroxychloroquine and azithromycin are generally well-tolerated medications, increased usage in the context of COVID-19 will likely increase the frequency of adverse drug events (ADEs),” said co-first author Nicholas J. Mercuro, PharmD, a pharmacy specialist in infectious diseases at BIDMC. Senior author Howard S. Gold, MD, an infectious disease specialist at BIDMC and an assistant professor of medicine at Harvard Medical School, said: “Based on our current knowledge, hydroxychloroquine for the treatment of COVID-19 should probably be limited to clinical trials.”

  • Epidemic Dictates an Open Exchange of Modeling Knowledge

    It has become increasingly clear that, depending on the computer model used, either we could still be in the midst of the pandemic with rising numbers of cases and deaths or we could be nearing the time to reintroduce society to normal operations. Why such disparity? Because each model works a bit differently and depending on the model used and assumptions added in, the results will change, sometimes dramatically.

  • U.S. Navy Releases "Unexplained Aerial Phenomena" Videos

    The U.S. Department of Defense earlier this week released three declassified videos of “unexplained aerial phenomena” (the official name for “unidentified flying objects,” or UFOs). The three videos released Monday had already been leaked to the press in 2007 and 2017. Believers in the existence of extraterrestrial life cheered the Pentagon’s release of the videos, but experts caution that earthly explanations usually exist for such sightings — and that when people do not know why something happened, it does not mean it happened because of aliens.

  • Predicting and Countering Cyberttacks

    The U.K Defense and Security Accelerator (DASA) announce nearly £1m to further develop technology that predicts and counters cyber-attacks. “This work will develop, adapt and merge the novel approaches explored in Phase 1 of the competition, to proactively defend deployed U.K. military systems and networks from the rapidly growing threat of offensive cyber action from aggressive adversaries,” DASA said.

  • Catching Nuclear Smugglers: Fast Algorithm Enable Cost-Effective Detectors at Borders

    Nations need to protect their citizens from the threat of nuclear terrorism. Nuclear security deters and detects the smuggling of special nuclear materials—highly enriched uranium, weapons-grade plutonium or materials that produce a lot of radiation—across national borders. A new algorithm could enable faster, less expensive detection of weapons-grade nuclear materials at borders, quickly differentiating between benign and illicit radiation signatures in the same cargo.

  • Waterfront Development Added Billions to Property Values Exposed to Hurricane Florence

    Rapid development in flood-prone zones during recent decades helped boost the amount of property exposed to 2018’s devastating Hurricane Florence substantially, a new study says. It estimates that the value of property in North Carolina and South Carolina potentially exposed to flooding at $52 billion—$42 billion more than at the start of the century (in 2018 dollars). While much development took place between 1950 and 2000, financial risk rose quickly afterward because much of it clustered along coastlines and adjacent to rivers and lakes, where buildings were more vulnerable to flooding.

  • New Privacy Threat Combines Device Identification with Biometric Information

    A new study by computer scientists has revealed a new privacy threat from devices such as smartphones, smart doorbells and voice assistants that allows cyber attackers to access and combine device identification and biometric information.

  • Coronavirus: Digital Contact Tracing Doesn’t Have to Sacrifice Privacy

    To make it safer to reduce the lockdown measures, proposals are being considered to use data from people’s smartphones to track their movements and contacts with potentially infected patients. Other systems involve monitoring the data trails of all citizens to generate useful information that helps to prevent the spread of the disease. All these approaches involve allowing the government, and in some cases private companies, to build a database of where we go, the people we associate with and when. Such intrusive tracking is more typically associated with totalitarian regimes and easily can be misused. Despite the good intentions, then, these measures raise serious concerns that collecting and sharing such data might pose a threat to citizens’ right to privacy.

  • Studying Ideologically Motivated Cyberattacks

    A John Jay College of Criminal Justice project on cyberterrorism is one of 13 selected by the Department of Homeland Security as part of the National Counterterrorism Innovation, Technology, and Education (NCITE) Center, a new DHS Center of Excellence. The John Jay project will study and aggregate ideologically motivated cyberattacks and will create a new, unique dataset – the Cyber-Extremist Crime Database (Cyber-ECDB) – which will track ideologically motivated cyberattacks against U.S. targets from 1998 to present.

  • Examining Australia’s COVIDSafe Tracing App

    The Australian government releases an App called COVIDSafe to help in tracing contacts of those infected with the coronavirus. As is the case with similar apps in other countries, COVIDSafe has raised privacy concerns, especially about the potential of abuse by government agencies and hacking by cybercriminals. The University of Sydney academics from the disciplines of cybersecurity, media, law and health comment on COVIDSafe, its pros and cons.
