The submitted wording is real, but it is not on the cited Phys.org URL and is not correctly attributed to Phys.org. It appears verbatim as two Key Takeaways bullets on a UC San Diego Today story by Lizelda Lopez, published March 09, 2026; the Phys.org page dated March 9, 2026 contains different prose and a Joel Wertheim quote instead.
