Defense NewsIsraelPrime Minister Benjamin Netanyahu on Sunday said Israel was "one step away from victory" in the Gaza war and vowed there would be no truce until Hamas frees all hostages.He was speaking in a cabinet meeting marking six months of the war that broke out on October 7 after an unprecedented attack on Israel by Hamas militants."We are one step away from victory," Netanyahu said. "But the price we paid is painful and heartbreaking."Speaking as truce talks were expected to resume in Cairo with international mediators, he said: "There will be no ceasefire without the return of hostages. It just won't happen."He stressed that "Israel is ready for a deal, Israel is not ready to surrender"."Instead of international pressure being directed at Israel, which only causes Hamas to harden its positions, the pressure of the international community should be directed against Hamas. This will advance the release of the hostages."Israel has faced a storm of international outrage over the killing of seven aid workers of the US-based food charity World Central Kitchen in a Gaza air strike on April 1.US President Joe Biden in a phone call with Netanyahu on Thursday demanded an "immediate ceasefire" and hinted at making US support for Israel conditional on curtailing the killing of civilians and improving humanitarian conditions.Netanyahu meanwhile accused Iran of being behind several attacks against Israel "through its proxies"."Anyone who hurts us or plans to hurt us -- we will hurt him. We put this principle into practice, all the time and in recent days," Netanyahu added.Fears that the war in Gaza could spread have intensified after Iran vowed to hit back for the killing of seven of its Revolutionary Guards in an air strike Monday on the consular annex of its embassy in Damascus.Iran's leaders have pledged retaliation, and the leader of Lebanon's Iran-backed Hezbollah movement, Hassan Nasrallah, has called the consulate strike a "turning point".

Space NewsChinaA recent study published in the journal Nature Astronomy sheds light on the long-standing mystery of the moon's weathered and cratered surface. Researchers from the Institute of Geochemistry in Guiyang, along with colleagues from Guangzhou and Macau, analyzed lunar soil samples collected by China's Chang’e 5 mission and made a groundbreaking discovery.The team identified titanium compounds, including Ti2O, which have never been observed in natural samples on Earth. These minerals likely formed due to intense vaporization and deposition processes triggered by the constant bombardment of micrometeorites from space.Micrometeorite impacts have long been recognized as significant agents in altering the lunar landscape. However, the precise mechanisms behind these transformations have remained elusive until now.The titanium compounds were found on a 9-micrometer-diameter meteorite impact crater on the surface of a Chang’e 5 glass beadThe discovery of Ti2O, found in two distinct structures on tiny glass beads retrieved by the Chang’e 5 spacecraft, marks a significant milestone. It becomes the seventh and eighth minerals ever discovered on the moon, following previous findings from US Apollo missions, Russian Luna missions, and China's Chang’e 5.Titanium, a common element on both Earth and the moon, typically exists as an oxide. However, the existence of Ti2O in lunar samples provides valuable insights into the lunar surface's geological processes.The formation scenario proposed by the Chinese team explains how a micrometeorite impact results in the vaporisation-deposition of Ti-oxide compounds on the lunar surfaceBy analyzing 25 glass beads from the Chang’e 5 samples, the researchers utilized advanced transmission electron microscopy techniques to examine their composition. They observed a tiny impact crater on one of the beads, where three titanium-containing minerals were detected: rutile (TiO2), trigonal Ti2O, and triclinic Ti2O.The team proposed that micrometeorites, traveling at high speeds, collided with ilmenite grains on the moon's surface, leading to melting, vaporization, and redeposition of the material onto the impact crater rim. This scenario aligns with predictions made by US planetary scientist Bruce Hapke five decades ago.The study's findings offer new insights into lunar weathering processes and may have implications for understanding similar phenomena on other airless planetary bodies in the solar system, such as Mercury and asteroids.The research was supported by various funding programs, including the National Key Research & Development Programme, the Strategic Priority Programme of the Chinese Academy of Sciences, and the National Natural Science Foundation of China.Overall, this discovery represents a significant step forward in unraveling the mysteries of the moon's geological history, providing valuable clues for future lunar exploration endeavors.
