European nations worked Monday to keep alive diplomatic efforts to curb the Israel-Iran war as the two countries traded strikes following the United States’ weekend attack on Iran’s nuclear program.  Calls for Tehran to enter talks with Washington appeared to fall on deaf ears. Tehran reached out to ally Russia for support instead. At a meeting of European Union foreign ministers in Brussels, diplomats expressed concern about the potential for Iranian retaliation to spark a wider war and global economic instability. U.K. Foreign Secretary David Lammy urged Iran to meet European officials and to open talks with the U.S. But Iran has rejected negotiations with Washington and a European official said no more talks with Iran are currently planned.

The war between Israel and Iran has raised concerns that Iran could try to close the Strait of Hormuz, the world’s most important oil chokepoint. The strait is between Oman and Iran. About 20 million barrels of oil per day, or around 20% of the world’s oil consumption, passed through it last year. Iran boasts a fleet of fast-attack boats and thousands of naval mines as well as missiles that it could use to make the strait impassable, at least for a time. If that happened, analysts expect the U.S. Navy would intervene to keep the strait open.

Although women face the threat of more injury risks in vehicle crashes, the crash test dummies used in U.S. safety tests are designed almost entirely around the body of a man. Maria Weston Kuhn, a survivor of a near-fatal accident, created a nonprofit to help change that. Her organization is asking members of Congress to sign onto a bill that would mandate the National Highway Traffic Safety Administration to upgrade the standards and add a new female dummy. A Michigan-based company called Humanetics has designed one, but the standard tests still involve a dummy from the 1970s based on an average-sized male. Even the company's upgraded male model, adopted by numerous other countries, still hasn't won final U.S. approval.
