The COVID-19 pandemic and killing of George Floyd along with other recent deaths of Black people at the hands of police have laid bare stark structural and systemic racial inequities and their impacts on the health and well-being of individuals and communities. While these events have brought health and health care disparities into sharp focus for the media and public, they are not new. These longstanding and persistent health disparities are symptoms of broader social and economic challenges that are rooted in structural and systemic barriers across sectors - including housing, education, employment, and the justice system - as well as underlying racism and discrimination. Amid this difficult time for our nation, the increased recognition and understanding of disparities could provide a catalyst for the challenging work required to address them.

Assassination of Iran's top nuclear scientist appears to have been carried out by what the New York Times calls "a high-tech, computerized sharpshooter kitted out with artificial intelligence and multiple-camera eyes, operated via satellite and capable of firing 600 rounds a minute." This and unmanned drones might herald a more expansive and ongoing set of targeted killings by state entities but also by networks, organizations, or even individuals and perhaps complicate traditional forensics in connecting actors with actions.

The weeding machine is a beast at almost 10,000 pounds. It boasts no fewer than eight independently-aimed 150-watt lasers, typically used for metal cutting, that can fire 20 times per second. They're guided by 12 high-resolution cameras connected to AI systems that can recognize good crops from bad weeds. The Laserweeder drives itself with computer vision, finding the furrows in the fields, positioning itself with GPS, and searching for obstacles with LIDAR. It drives 5 miles/hour and can clear 15-20 acres in a day.

We have all heard of citronella, commonly known to be a natural mosquito repellant. "Biopesticides are substances or mixtures of biological substances used to prevent, destroy, kill, control, or mitigate pests." This article is short but provides a valuable list of biopesticide plants that can be used as the basis for research.

"This crosses a moral, legal and technical line, taking us to a dark and dangerous world," UNSW Sydney AI professor Toby Walsh told Futurism. "Such weapons will be used by terrorists and rogue states. They will be weapons of terror."

DRIVER-WATER TREATMENT TECHNOLOGY Ozone water treatment oxidizes iron, manganese, and sulfur in your well water to form insoluble metal oxides or elemental sulfur. These insoluble particles such as rust, are then removed by filtration which is typically activated carbon, manganese dioxide, or other media such as filter sand. Ozone is much faster at killing bacteria and oxidizing iron and manganese compared to chlorine or peroxide. One advantage for home use is that ozone is quite unstable and will degrade over a time frame ranging from a few seconds to 30 minutes.
