    ‘Internet of things’ could be an unseen threat to elections

    The app failure that led to a chaotic 2020 Iowa caucus was a reminder of how vulnerable the democratic process is to technological problems—even without any malicious outside intervention. Far more sophisticated foreign hacking continues to try to disrupt democracy, as a rare joint federal agency warning advised prior to Super Tuesday. Russia’s attempt to interfere in the 2016 election has already revealed how this could happen: social media disinformation, email hacking and probing of voter registration systems.

  • Discovery of accurate and far more efficient algorithm for point set registration problems

    Discovery of accurate and far more efficient algorithm for point set registration problems

    A point set registration problem is a task using two shapes, each consisting of a set of points, to estimate the relationship of individual points between the two shapes. Here, a “shape” is like a human body or face, which is similar to another body or face but exhibits morphological diversity. Taking the face as an example: the center position of the pupil of an eye varies depending on individuals but can be thought to have a correspondence with that of another person. Such a correspondence can be estimated by gradually deforming one shape to be superimposable on the other. Estimation of the correspondence of a point on one shape to a point on another is the point set registration problem. Since the number of points of one shape could be millions, estimation of correspondence is calculated by a computer. Nonetheless, up to now, even when the fastest conventional method was used, it took a lot of time for calculation for registration of ca. 100,000 points. Thus, algorithms that could find a solution far faster without affecting accuracy have been sought. Furthermore, preliminary registration before automated estimation was a prerequisite for the conventional calculation method, so algorithms that do not need preliminary registration are desirable.

  • New lithium batteries from used cell phones

    New lithium batteries from used cell phones

    Lithium-ion batteries are used around the world, and though over the last few years they have had some competition, such as sodium and magnesium, they continue to be indispensable due to their high density and capacity. The issue is this: this metal has major availability and concentration problems. Almost 85% of its reserves are located in what is known as the Lithium Triangle, a geographical area found on the borders of Argentina, Bolivia and Chile. In addition, it seems that demand will rocket over the next few decades because of the implementation of electric vehicles. Each car equals about 7,000 cell phone batteries, so reusing their different components has become an issue of utmost importance.

  • World experts and funders set priorities for COVID-19 research

    World experts and funders set priorities for COVID-19 research

    Leading health experts from around the world have been meeting at the World Health Organization’s Geneva headquarters to assess the current level of knowledge about the new COVID-19 disease, identify gaps and work together to accelerate and fund priority research needed to help stop this outbreak and prepare for any future outbreaks.

    The 2-day forum was convened in line with the WHO R&D Blueprint – a strategy for developing drugs and vaccines before epidemics, and accelerating research and development while they are occurring.

    “This outbreak is a test of solidarity — political, financial and scientific. We need to come together to fight a common enemy that does not respect borders, ensure that we have the resources necessary to bring this outbreak to an end and bring our best science to the forefront to find shared answers to shared problems. Research is an integral part of the outbreak response,” said WHO Director-General Dr Tedros Adhanom Ghebreyesus. “I appreciate the positive response of the research community to join us at short notice and come up with concrete plans and commitment to work together.”

    The meeting, hosted in collaboration with GloPID-R (the Global Research Collaboration for Infectious Disease Preparedness) brought together major research funders and over 300 scientists and researchers from a large variety of disciplines. They discussed all aspects of the outbreak and ways to control it including:

    • the natural history of the virus, its transmission and diagnosis;
    • animal and environmental research on the origin of the virus, including management measures at the human-animal interface;
    • epidemiological studies;
    • clinical characterization and management of disease caused by the virus;
    • infection prevention and control, including best ways to protect health care workers;
    • research and development for candidate therapeutics and vaccines;
    • ethical considerations for research;
    • and integration of social sciences into the outbreak response.

    “This meeting allowed us to identify the urgent priorities for research. As a group of funders we will continue to mobilize, coordinate and align our funding to enable the research needed to tackle this crisis and stop the outbreak, in partnership with WHO,” said Professor Yazdan Yazdanpanah, chair of GloPID-R. “Equitable access – making sure we share data and reach those most in need,  in particular those in lower and middle-income countries, is fundamental to this work which must be guided by ethical considerations at all times.”  

    During the meeting, the more than 300 scientists and researchers participating both in person and virtually agreed on a set of global research priorities. They also outlined mechanisms for continuing scientific interactions and collaborations beyond the meeting which will be coordinated and facilitated by WHO. They worked with research funders to determine how necessary resources can be mobilized so that critical research can start immediately.

    The deliberations will form the basis of a research and innovation roadmap charting all the research needed and this will be used by researchers and funders to accelerate the research response.

  • Female Genital Mutilation Hurts Women and Economies

    Female Genital Mutilation Hurts Women and Economies

    Female genital mutilation (FGM) exacts a crippling economic as well as human cost, according to World Health Organization (WHO).

    “FGM is not only a catastrophic abuse of human rights that significantly harms the physical and mental health of millions of girls and women; it is also a drain on a country’s vital economic resources,” said Dr Ian Askew, Director of WHO’s Department of Sexual and Reproductive Health and Research. “More investment is urgently needed to stop FGM and end the suffering it inflicts.”

    New modelling reveals that the total costs of treating the health impacts of FGM would amount to USD 1.4 billion globally per year, if all resulting medical needs were addressed. For individual countries, these costs would near 10% of their entire yearly expenditure on health on average; in some countries, this figure rises to as much as 30%.

    The interactive modelling tool that generated these data was launched on the International Day of Zero Tolerance for Female Genital Mutilation.

    Severe physical and mental health impacts for women and girls

    Women and girls living with FGM face serious risks to their health and well-being. These include immediate consequences after being cut, such as infections, bleeding or psychological trauma, as well as chronic health conditions that can occur throughout life.

    Women who have undergone the procedure are more likely to experience life-threatening complications during childbirth. They may face mental health disorders or suffer chronic infections. They may also have pain or problems when they menstruate, urinate or have sexual intercourse. 

    All of these conditions warrant much-needed medical attention and care.

    “High healthcare costs for countries mount because of the tragic personal impacts on women and girls. Governments have a moral responsibility to help end this harmful practice,” says Dr Prosper Tumusiime, Acting Director for Universal Health Coverage and the Life Course in the African Regional Office of WHO. “FGM hurts girls, imposes lifelong health risks on the women they become, and strains the healthcare systems that need to treat them.”

    Preventing FGM brings major benefits for women, girls, communities and economies

    Using data from 27 high-prevalence countries, the Cost Calculator demonstrates clear economic benefits from ending FGM. If it were abandoned now, it shows that the associated savings in health costs would be more than 60% by 2050.

    In contrast, if no action is taken, it is estimated that these costs will soar by 50% over the same time period, as populations grow and as more girls undergo the procedure.

    Since 1997, great efforts have been made to end FGM, through work within communities, research, and changes in legislation and policy. 26 countries in Africa and the Middle East now explicitly legislate against FGM, as well as 33 other countries with migrant populations from FGM-practicing countries.

    WHO is also working with countries to raise awareness of the harmful impacts of the practice among their health workers, and to engage them in prevention efforts.

    “Many countries and communities are showing that abandoning female genital mutilation is possible,” states Dr Christina Pallitto, scientist at WHO. “If countries invest to end female genital mutilation, they can prevent their girls from undergoing this harmful practice and promote the health, rights and well-being of women and girls.”

    Female genital mutilation is internationally recognized as a human rights violation. It has no medical benefits and causes only harm. WHO’s position is that FGM must never be carried out.

    More on FGM

    Notes for Editors

    About FGM

    FGM includes procedures that intentionally alter or cause injury to the female genital organs for non-medical reasons. More than 200 million girls and women alive today are estimated to have undergone the practice across 30 countries in Africa, the Middle East and Asia where FGM is concentrated.

    FGM is mostly carried out on young girls between infancy and 15 years of age.

    About the FGM Cost Calculator

    The WHO FGM Cost Calculator shows the economic cost of treating the health complications caused by FGM across 27 high-prevalence countries. These costs were calculated using the WHO One Health tool and other available scientific evidence.

    Users of the tool can calculate costs by country in a ‘business as usual’ scenario; a scenario of partial abandonment of FGM, and full abandonment of FGM over a 30-year period. In addition, the distribution of costs by different types of health complications is presented by country.

    The tool does not consider other indirect costs that hit families and communities, or the socio-economic impacts of the practice, which would be significantly higher still.

    The 27 countries modelled include Benin, Burkina Faso, Central African Republic, Còte d’Ivoire, Cameroon, Chad, Djibouti, Egypt, Eritrea, Ethiopia, Ghana, Guinea, Gambia, Guinea-Bissau, Iraq, Kenya, Mali, Mauritania, Niger, Nigeria, Soudan, Senegal, Sierra Leone, Somalia, Togo, United Republic of Tanzania, Yemen.

  • How long should children play video games?

    How long should children play video games?

    A new study indicates that playing video games for a limited amount of time each week may provide benefits to children, but too much can be detrimental. The findings are published in the Annals of Neurology.

    There’s much debate over the potential benefits and risks of video gaming in children and teens. To provide some clarity, Jesus Pujol, MD, of the Hospital del Mar in Spain, and his colleaguesinvestigated the relationship between weekly video game use and certain cognitive abilities and conduct-related problems.

    In their study of 2442 children aged 7 to 11 years, the researchers found that playing video games for one hour per week was associated with better motor skills and higher school achievement scores, but no further benefits were observed in children playing more than two hours each week.
