一 | JERUSALEM -- Since Israel activated the Iron Dome in 2011, the cutting-edge rocket-defense system has intercepted thousands of rockets fired from the Gaza Strip.The system has given residents a sense of security, and Israelis can often be seen watching the projectiles flying through the skies and destroying their targets overhead.But the current war with Hamas might be its stiffest challenge yet.In just two weeks, Hamas has fired 7,000 rockets toward Israel, according to the Israeli military. That is more than any of the previous four wars fought between Israel and Hamas since the militant group seized power in Gaza in 2007. On Oct. 7 alone, the first day of fighting, Hamas launched at least 2,000 rockets, according to data from West Point. Lebanon's Hezbollah has also fired hundreds of rockets along Israel's northern front since the fighting began.Most of the rockets have been intercepted. But some have managed to get through, killing at least 11 people and hitting buildings as far away as Tel Aviv, according to Israeli officials.Here is a look at the accomplishments — and limitations — of the Iron Dome.The Iron Dome is a series of batteries that use radars to detect incoming short-range rockets and intercept them.Each battery has three or four launchers, 20 missiles, and a radar, according to Raytheon, the U.S. defense giant that co-produces the system with Israel's Rafael Defense Systems.Once the radar detects a rocket, the system determines whether the rocket is headed toward a populated area. If so, it launches a missile to intercept and destroy the rocket. If the system determines the rocket is headed to an open area or into the sea, it is allowed to land, thus conserving missiles. According to the military, all interceptions occur in Israeli airspace.The military declined to comment on how many Iron Dome batteries are currently deployed. But as of 2021, Israel had 10 batteries scattered around the country, each able to defend a territory of 60 square miles (155 square kilometers), according to Raytheon. It is roughly 90% effective, according to Rafael.But it can get overwhelmed if a mass barrage of rockets is fired, allowing some to slip through. While it has performed well so far, the risk could be raised if Hezbollah enters the war. Hezbollah has an estimated 150,000 rockets and missiles.Each missile costs an estimated $40,000 to $50,000, according to the Institute for National Security Studies, a Tel Aviv think tank.The U.S. has invested heavily in the system, helping with development costs and replenishing it during times of fighting.President Joe Biden has said he will ask Congress for $14.3 billion in military aid for Israel. The majority of that would help with air and missile defense systems, according to the White House.“We’re surging additional military assistance, including ammunition and interceptors to replenish Iron Dome,” Biden said.___Find more of AP’s coverage at https://apnews.com/hub/israel-hamas-war。

二 | (ECNS) -- Humanoid robots broke several long-standing human athletic records at the 2026 World Humanoid Robot Games in Beijing on Sunday, highlighting rapid advances in their physical capabilities. The five-day games brought together 666 teams and 2,056 robots from 16 countries and regions across six continents to compete in 51 events. In a 100-meter preliminary race during the opening ceremony, a robot developed by the Tianzhuo team clocked 9.39 seconds, beating Jamaican sprinter Usain Bolt’s human world record of 9.58 seconds. The result also marked a major improvement from the best time of 21.50 seconds recorded at last year’s games. A Tien Kung Ultra humanoid robot from Beijing also set a new high-jump record, clearing 2.8843 meters from a standing position, well above last year’s winning mark of 95.641 centimeters. During pre-event testing, Honor’s “Lightning” humanoid robot completed the 100 meters in 9.32 seconds and reached a peak speed of 14.5 meters per second, with both figures surpassing human records. The video of this robot was later reposted and liked by Tesla CEO Elon Musk. In April, Lightning won the 2026 Beijing E-Town Humanoid Robot Half Marathon in 50 minutes and 26 seconds. The robot completed the 21.1-kilometer race faster than the winner of the previous edition and also surpassed the human world record, according to Honor. (By Helen Mo, intern Liu Shuangjing) 。
