Virat Kohli breaks another 20-year-old record of Sachin Tendulkar in World Cup semifinal
New Delhi: Star Indian batsman Virat Kohli on Wednesday broke a 20-year-old record of Sachin Tendulkar by becoming the batter with most runs in a single edition of a World Cup.
Playing against New Zealand in the semifinal match at Wankhede Stadium Kohli went past Sachin Tendulkar’s record 673 runs when he reached 80 runs in his innings today.
Sachin had scored 673 runs in the 2003 edition of the ICC World Cup. Mathew Hayden had scored 659 runs in the 2007 edition while current Indian skipper Rohit Sharma had scored 648 runs in the 2019 ODI World Cup.
Kohli was unbeaten at 80 at the time of posting of this report and was inching towards his 50th ODI century which would also result in him breaking the record of Sachin Tendulkar for most ODI century. The two batters are currently at the top with 49 centuries each.

China tests new Hydrogen bomb without nuclear fusion
Beijing: China has reportedly tested a new kind of explosive device that uses hydrogen but does not involve any nuclear materials. This new weapon was developed by the China State Shipbuilding Corporation (CSSC). It works differently from traditional hydrogen bombs, which rely on nuclear fusion. Instead, this device uses a chemical reaction with a substance called magnesium hydride. The explosion creates a powerful fireball that gives off extreme heat for a longer time, reported Economic Times.
The explosive weighs only 2 kilograms and uses a unique method to create a powerful blast. Magnesium hydride, which stores hydrogen at high densities, breaks down quickly when triggered by a normal explosive. This releases hydrogen gas, which then mixes with air and catches fire. The result is a fireball with temperatures above 1,000°C much hotter than regular explosives like TNT.
Quoting Wang Xuefeng, a top scientist at the China State Shipbuilding Corporation (CSSC), The Economic Times reported that hydrogen explosions require very little energy to ignite and can spread rapidly. Wang explained that such fires possess the intensity to burn through strong materials, including aluminium alloys. Due to its precision and destructive power, the device could be highly effective in targeted military strikes.
During a field test, the explosive showed a peak pressure of 428.43 kilopascals at a distance of two meters. This is around 40% of the pressure made by TNT. But the real strength of this device lies in the heat it produces. While most explosives create a quick shockwave, this one keeps burning at very high temperatures for more than two seconds.
This long-lasting heat could make the explosive useful for hitting specific military targets, such as power plants or communication centers. It could also be used to block enemy forces by burning roads or transport routes, making them unusable.
