  • How Vancouver is saving addicts' lives

    Rather than treat opioid users like criminals, Vancouver has deemed it a public health crisis. The city, especially its downtown east side, witnessed 1,500 deaths in just one year from opioid use. Its approach is unique and multi-pronged – making Narcan, an overdose antidote, available to everyone, opening safe injection sites, and having a police presence – without arrests – on blocks where using remains high.

  • Scientists are using bacteria to remove harmful contaminants from our water. Here's how.

    It turns out that bacteria can do a lot more than contaminate water--some species break down toxic chemicals and remove heavy metals. Active sites already clean water in states like Kansas, Utah, Texas, and California; for example, one Californian groundwater treatment plant can clean 2,000 gallons of perchlorate-contaminated water per minute. Though some logistical and technical hurdles remain, these bacterial allies in the fight against water pollution are very promising.

The goal of these discussions is to decrease the amount of unintended pregnancies and as a result increase women’s body autonomy and decrease medical spending.

  • Mandera, Isiolo step up war against maternal deaths

    Two regions within Kenya, Mandera and Isiolo, have made significant strides in reducing their rate of maternal mortality cases. Both counties employed similar tactics, such as improving facility quality, increasing the number of healthcare workers, and training local community volunteers to advocate for ante-natal care. Among other metrics, Mandera now records 588 deaths per 100,000 live births (down from 3,795), and Isiolo now has 57 facilities (up from 47) to make healthcare more accessible.

  • An Island Nation's Health Experiment: Vaccines Delivered by Drone

    Drones can deliver vaccines and medicines to isolated and underserved areas. The South Pacific archipelago of Vanuatu now relies on drones to distribute vaccines to children in remote locations. Flights by drone are cheaper than boat trips and can reach portions of the volcanic islands otherwise inaccessible with fragile equipment. Partnerships between health ministries, NGOs, and tech companies have already seen drones implemented to deliver vaccines, medicines, and other medical necessitates in countries such as Malawi and Rwanda.
