Biological Warfare Canaries

In the face of germ warfare, just knowing you are under attack is half the battle

Once a year a select group of scientists and engineers gathers at Dugway Proving Ground, a salt flat in the Utah desert 65 km from the nearest traffic light. They are there by invitation of the U.S. Defense Department's Joint Program Office for Biological Defense to compete in an unusual showdown: to field-test their systems for detecting biological warfare agents.

This is no idle contest; this is serious business, critical to national security. As the recent contentious negotiations over the 29-year-old Biological and Toxins Weapons Convention have shown, concern over the possibility of a biological attack is mounting worldwide.

Shoppers are seeing more and more empty shelves, as stores around the world struggle to keep products stocked. The situation is the result of supply-chain issues caused in part by the COVID-19 pandemic. The product-unavailability rate increased from 5 percent to 15 percent during the past three years, according to the Consumer Brands Association.

To make it easier for stores to track inventory, startup Wisy developed an AI platform that uses image recognition to detect which products are out of stock or running low, as well as those that are available but haven’t yet been put on display.

When Gamers Get Nasty

Researchers grapple with subjectivity as they develop algorithms to detect toxicity in online gaming

Online gaming is a chance for players to come together, socialize, and enjoy some friendly competition. Unfortunately, this enjoyable activity can be hindered by abusive language and toxicity, negatively impacting the gaming experience and causing psychological harm. Gendered and racial toxicity, in particular, are all too common in online gaming.

To combat this issue, various groups of researchers have been developing artificial-intelligence models that can detect toxic behavior in real time as people play. One group recently developed a new such model, which is described in a study published 23 May in IEEE Transactions on Games. While the model can detect toxicity with a fair amount of accuracy, its development demonstrates just how challenging it can be to determine what is considered toxic—a subjective matter.
