"Mathematicians' Bold Journey to Precision"

Mathematicians Kevin Ren and Hong Wang have posted a proof of the Furstenberg set conjecture, a problem that has stumped mathematicians for two decades. The conjecture involves determining the minimum amount of dust covering an endless piece of paper with lines. Ren and Wang's proof, which is still a preprint and awaiting thorough review, combines two special cases previously proven by other mathematicians. The probability of correctness is estimated at 95%, and Ren hopes the final journal version will be as elegant as a work of art.

The Truth Behind the LK-99 Room-Temperature Superconductor Hoax

Recent studies have confirmed that LK-99, a material previously claimed to be a room-temperature superconductor, is actually an insulator. The initial excitement surrounding the substance was due to impurities in the samples. The preprint paper published by a team in South Korea, which claimed to have created a superconductor-like material using common ingredients, lacked peer review and raised doubts from the start.
