Death by Frog Toxin?

New forensic testing shows Russian opposition leader Alexei Navalny was likely killed with epibatidine, a powerful neurotoxin found in South American poison dart frogs, according to five European governments. The claim reignites scrutiny over the circumstances of Navalny's 2024 death. 

The UK, France, Germany, Sweden, and the Netherlands said that independent lab analysis detected the rare toxin in preserved tissue samples from Navalny's body. They argue there is no credible natural explanation for its presence and have reported the findings to the Organization for the Prohibition of Chemical Weapons as a potential violation of international law. Scientists note epibatidine is not known to occur naturally in Russia, though lab-synthesis is possible; even tiny amounts can disrupt the nervous system, causing paralysis, respiratory failure, and death.

Navalny died Feb. 16, 2024, while serving a lengthy prison sentence in a remote Arctic penal colony (see timeline and background). Russia denies any involvement, maintaining he died of natural causes.

 

Canada Curling Controversy

Canada's men's curling team was accused of cheating Friday night, with Sweden claiming Canadian player Marc Kennedy touched the curling stone after its release. Kennedy—who responded with expletives—accused the Swedes of intentionally filming and premeditating the conflict; however, the team did not bring a formal complaint. See the disputed delivery here (via X). 

Less than 24 hours later, the Canadian women's team was accused of the same violation, with officials removing the rock during an 8-7 loss to Switzerland. On Sunday, Britain's men's team faced a similar ruling when Scottish curler Bobby Lammie was judged to double‑touch his stone in a round‑robin win over Germany. Observers compared the controversy to the 2014-16 “Broomgate” scandal, in which engineered brush heads gave precise control over the stone’s trajectory (deep dive listen).   

Separately, the US delegation secured five gold medals (17 total) through the first half of the Olympics. One highlight has been the women’s hockey team, which routed host Italy 6-0 and faces Sweden in the semifinals today. Competition concludes Sunday; see the full standings here.

 

Year of the Fire Horse

Lunar New Year celebrations kick off tomorrow, ushering in the Year of the Fire Horse in the Chinese zodiac. The 15-day festivities, observed by billions worldwide, start with the new moon and end with the Lantern Festival. China anticipates a record 9.5 billion trips during the 40-day travel rush around the holiday, the world’s largest annual human migration.

The horse is the seventh animal in the 12-year zodiac cycle and symbolizes energy, independence, and ambition. Those born in horse years are seen as dynamic, courageous, and charismatic. Many see the Year of the Fire Horse as a time to take bold steps, embrace change, and pursue new opportunities. The last Fire Horse year occurred in 1966; notable births include Adam Sandler, Gordon Ramsay, Halle Berry, and Helena Bonham Carter. See your zodiac animal here.

Traditions focus on family and fortune (see our overview), including gifting lai see or hóngbāo to children—red envelopes filled with "lucky money." See a guide to the holiday, closely associated with the Spring Festival and Chinese New Year, here

 Presidents Day Explained 

 

Today marks the 147th anniversary of Presidents Day, established in 1879. Originally honoring George Washington—whose birthday was already informally celebrated nationwide—the holiday was moved to the third weekend of February in 1971, placing it between the birthdays of Washington and Abraham Lincoln (and creating a three-day weekend).
