  • Organic fertilizers to lift African farmers out of poverty

    After realizing that chemical fertilizer was doing more harm to the land than good in Burkina Faso, a Burkinese agronomist created a fertilizer from organic waste that has allowed the land to once again become fertile. Although the organic fertilizer promises a much higher increase in yields, chemical fertilizer is still widely used in the region.

  • Dengue breakthrough after mosquitoes laced with natural bacteria

    Injecting mosquito eggs with Wolbachia, a naturally occurring bacteria, is showing promise for reducing the cases of dengue in parts of Indonesia. Although dengue cases have been increasing, in areas of Indonesia where mosquitoes infected with Wolbachia were released, "their capacity to transmit the virus that causes dengue was vastly reduced," as compared to areas with untreated mosquito populations.

  • The mosquito strategy that could eliminate dengue

    In Indonesia, Wolbachia-carrying mosquitoes are transmitting dengue at a much slower rate than those not infected with the bacterium according to a controlled research study that expands on existing experimentation conducted elsewhere in the world. Although the trial was cut short due to the prevalence of COVID-19, the results were substantial enough that researchers are encouraging efforts to scale the technology worldwide.

  • Toward a Cure: Cities Declare Racism a Public Health Crisis

    Milwaukee was one of the first U.S. cities to show that communities of color were disproportionately impacted by the coronavirus pandemic because of a framework that had been established and implemented after the city and county declared racism a public health crisis. The resolution allowed for city officials to track data that framed "disparities in health outcomes through a racial lens." Now, 70 other jurisdictions have made similar declarations and additional efforts are underway to address a range of health issues tied to racial trends.

  • Study Finds Painting Eyes On Cows' Butts Can Save Their Lives

    As a way to prevent livestock from being attacked by predators and to decrease conflict between farmers and big cats, a pair of conservation biologists painted eyes on the backsides of cattle to fool carnivores during their hunt. A study in Botswana showed that cows painted with artificial eyes on their behinds tricked predators into thinking they’ve been seen by their prey. While it’s not a perfect protection method for cattle, over the four years of the study, none of the cows with the colorful posteriors were killed compared with control groups.

  • Behind the masks: Meet the people who keep Gauteng's field hospital going

    A color-coded system is being adopted at hospitals throughout South Africa after seeing success in Taiwan during the COVID-19 pandemic. The system uses red, yellow, and green color-coding to warn health care officials about their likelihood of coming into contact with someone who could expose them to the coronavirus. The tactic is just one of several new measures that have been implemented to keep frontline workers safe.

  • Pandemic pushes expansion of 'hospital-at-home' treatment

    Although offering at-home care has been a practice for some time, the coronavirus pandemic has helped prompt more health insurance companies to allow health care workers to implement the practice at a larger scale. Treating patients in their homes doesn't just reduce the caseload for doctors in hospitals but also has been shown to have positive effects on the patient's overall health and well-being. Since the change in health insurance police, "interest in the programs has skyrocketed."

  • How an Indigenous Community in Brazil Used Tech to Contain the Coronavirus

    An indigenous community in Brazil has been able to keep their count of coronavirus cases low during the pandemic largely due to the use of contact tracing. Using technology that was already in existence for the purpose of tracking "archaeological, sacred places and ancestral settlements, as well as cultivated areas," the community was able to identify potential cases, test those who had been exposed and quarantine anyone who tested positive.

  • How Taiwan is battling coronavirus with tech, crowdsourced data and trust

    Taiwan has recorder fewer than 500 cases of COVID-19, and it is largely due to the country's reliance on "digital platforms to keep the public updated about medical supply availability and to monitor the status of quarantining citizens." From strict quarantine protocols – that include both monetary incentives and consequences – to a crowdsourcing app that shows mask availability, technology is driving much of Taiwan's response.

  • On Native American Land, Contact Tracing Is Saving Lives

    As coronavirus spread throughout the White Mountain Apache tribe in Arizona residents on the reservation turned to contact tracing – not to slow the spread, but to identify those who were high risk and may be infected with the virus, before they became too ill to recover. This strategy focused on testing blood oxygen levels and has resulted in a far lower mortality rate among the tribe as compared to the state. Now, researchers think it could serve as a model for other "hard-to-reach" communities.
