The White House is monitoring reports of a suspected plague case in Russia after a 27-year-old institute worker died and 189 people were hospitalized following contact with her. The pneumonic plague is caused by the same bacteria as the bubonic plague, and can spread from person to person through airborne respiratory droplets. American officials continue to evaluate the potential outbreak and its broader biosecurity implications: https://interestingengineering.com/health/suspected-russian-plague-white-house-scrutiny

Russian authorities have not confirmed the diagnosis, while a hospital in the Irkutsk region has been placed under quarantine: https://kyivindependent.com/plague-death-triggers-quarantine-mask-mandates-in-russias-irkutsk-region-in-siberia/

Global Study Finds Women Report More Pain Than Men

A major Nature Medicine study analyzing data from more than 6 million people in 118 countries (1990–2025) found that women reported higher pain prevalence than men across all 11 body sites studied, with the largest gaps in headache, facial and abdominal pain. Pain increased sharply before age 55 and peaked at age 75 and older. Researchers also highlighted persistent disparities in how women’s pain is diagnosed and treated.

Generating up to 100 times more antiviral drug candidates than was previously practical — in weeks rather than months or years — could improve the odds of finding a drug quickly when necessary.

Traditional antiviral drug discovery relies on screening massive libraries of molecules to identify "hits" that inhibit viral replication. However, creating diverse chemical candidates is typically a slow, complex bottleneck that takes months or years. Researchers at Simon Fraser University have supercharged this process by developing streamlined synthesis methods that can generate molecule libraries up to 100 times larger in just weeks. By dramatically expanding the volume and variety of candidate compounds available for screening early on, scientists can quickly pinpoint viable drug candidates, cut years off the early stage of development, and mount a faster response against emerging pandemic and viral threats.

An electrical engineer at Portland State University, Josh Méndez, has helped solve the classic science-demonstration mystery of why a pickle glows orange when electrocuted. After testing over 100 pickles, Méndez found that the phenomenon combines two leading theories: electrical current flowing through the salt brine creates gas pockets and a tiny electric arc (spark discharge), which then ignites volatile hydrogen gas generated by electrolysis at the negative electrode. The characteristic bright orange color itself comes from the sodium ions in the brine being excited by the spark.
