Brent slid below $90/bbl in early trade as mediators push the U.S. and Iran toward a potential new ceasefire. ING said the talks will not be easy and significant gaps remain between Washington and Tehran. Houthis announced a blockade of Saudi shipping — an action that could severely disrupt supplies by preventing oil bound for Asia from transiting the Bab al-Mandeb — but early price action suggests markets may doubt the blockade will succeed.

Wang Kejian’s team at the China Rice Research Institute reported development of a one-line hybrid rice, Yixi No.1, achieving stable cloning efficiency above 99% and normal fertility; the study was published July 21 in the journal Vita. By contrast, China’s widespread three-line and two-line hybrid systems suffer genetic segregation and cannot be used to retain seed, forcing annual production from male-sterile and restorer lines — a process the team says is technically demanding, higher risk and typically drives hybrid seed costs to more than 10x conventional rice seed. Experts note hybrid rice has been indispensable to China’s and global food security.
