Defense NewsIranIran announced on Saturday that it had apprehended members of the ISIL (ISIS) group who were allegedly plotting an attack at the end of the Muslim holy month of Ramzan, Al Jazeera reported. The breakthrough came after a vigilant citizen in Mahdasht, located in the Alborz province, approximately 60km (37 miles) west of Tehran, alerted law enforcement, according to police spokesman Saeed Montazerolmahdi. This tip-off led to the arrest of a "senior" ISIL figure named Mohammad "Ramesh" Zaker. Montazerolmahdi revealed that Zaker and two other ISIL operatives were taken into custody, while an additional eight individuals accompanying the alleged terrorists were also arrested, as reported by Al Jazeera. The group was purportedly planning a suicide attack during Eid al-Fitr, the festival marking the end of Ramzan. This development follows previous attacks attributed to ISIL in Iran, including twin bombings during a ceremony in Kerman in January, which claimed nearly 100 lives and left over 200 wounded. The Islamic State in Khorasan Province (ISIS-K), the Afghanistan-based branch of ISIL, claimed responsibility for the Kerman assault. Iran responded by arresting 35 individuals linked to the attacks, including an ISIS-K commander. In addition to the Kerman incident, ISIL has been implicated in other attacks on Iranian soil, such as assaults on a major Shia shrine in Shiraz. Notably, the group has targeted symbols of Iranian authority, including the parliament and the tomb of Ayatollah Ruhollah Khomeini in 2017, according to Al Jazeera. Meanwhile, Iran faces heightened security challenges amidst escalating tensions in the region, exacerbated by Israel's military actions in Gaza. Recently, armed militants from the Sunni separatist group Jaish al-Adl launched attacks on two bases of the Islamic Revolutionary Guard Corps (IRGC) in the southeastern province of Sistan-Baluchestan. This prompted funeral processions for slain IRGC members across various provinces, including Lorestan and Mazandaran. Furthermore, Iran mourned the loss of Brigadier-General Mohammad Reza Zahedi, a senior IRGC commander killed in an Israeli airstrike on the Iranian consulate building in Damascus, Syria. Speaking to a crowd in Tehran on Saturday, the chief of staff of the Iranian armed forces, Mohammad Bagheri, said "the criminal US and the cruel and child-killing Zionists must know that the life of the regime [Israel] is coming to an end, and there is not much left until its decay and destruction". "Air strikes on a consulate, as a protected mission under international accords, have no meaning but madness from the Zionist regime because it is harming and killing itself. If politicians in Israel had any credibility left, this move destroyed it," he said, renewing Iran's vow for revenge for its killed commanders, Al Jazeera reported.

Defense NewsIsrael & IranIran said it asked the US to “step aside” as the country prepares a response to a suspected Israeli attack on its consulate in Syria while Hezbollah, its main proxy in the Middle East, warned the Jewish state it’s prepared for war.In a written message to Washington, Iran “warned the US not to get dragged into Netanyahu’s trap,” Mohammad Jamshidi, the Iranian president’s deputy chief of staff for political affairs, wrote on X, referring to Israeli Prime Minister Benjamin Netanyahu. The US should “step aside so that you don’t get hit.”“In response, the US asked Iran not to hit American targets,” Jamshidi said.The US hasn’t commented on the alleged message Iran had sent.CNN reported that the US is on high alert and is preparing for a “significant” response from Iran against Israeli or American targets in the region. The network cited an unnamed US official.NBC, citing two unnamed US officials, said President Joe Biden’s administration is concerned any attack could be inside Israel, specifically against “military or intelligence targets, rather than civilians.”The Biden administration did take the unusual step of communicating directly to Iran that the US was unaware Monday’s strike in Damascus would happen, Bloomberg reported. That suggested the US was trying to prevent its own forces and bases in the Middle East being attacked.The Islamic Republic has said it will deliver a “slap” to Israel, its arch enemy. Still, it’s unclear when that would happen or whether Iran would try to attack Israel directly or through one of its proxy groups such as Hezbollah, based in Lebanon.The airstrike hit the Iranian consulate in Damascus, killing at least seven Iranians, including two generals. While Israel has repeatedly targeted Iran-linked assets in Syria over the past few months, this was the first time an attack struck an Iranian diplomatic building.Israel has been on alert since then, canceling home leave for combat troops, calling up reserves and bolstering air defenses. Its military scrambled navigational signals over Tel Aviv on Thursday to disrupt GPS-navigated drones or missiles that might be fired at the country.Hezbollah’s leader, Hassan Nasrallah, on Friday said a response from Iran is undoubtedly coming. But, he said, his group won’t “interfere in such decisions.”“And after that, how Israel will behave, the region would enter in a new phase,” Nasrallah said in a televised speech.Nasrallah, who lives in hiding, highlighted the coordinated work of Iran’s so-called resistance groups in the region.Hezbollah, the Middle East’s most powerful militia, said the group hasn’t used “its primary arsenal” in the daily skirmishes with Israel along the southern border of Lebanon since the start of the Israel-Hamas war on Oct. 7.Hezbollah is “completely prepared and ready” for any war with Israel, Nasrallah said.

Science NewsChinaArchaeologists in China have made a significant breakthrough in unraveling the mysteries surrounding Emperor Wu of the Northern Zhou dynasty, who ruled over 1,500 years ago until his untimely death at the age of 36. Utilizing innovative methods to analyze ancient DNA extracted from the emperor's bones, researchers from Fudan University reconstructed his facial features and shed light on the potential causes of his demise.Emperor Wu's death has long been a subject of speculation, with ancient texts suggesting poisoning as a possible cause. However, recent findings published in the journal Current Biology propose an alternative theory. Through a meticulous examination of the emperor's genetic material, the research team suggested that he may have been predisposed to stroke, challenging previous assumptions about his cause of death.The study involved a combination of traditional forensic techniques and advanced DNA analysis, allowing researchers to reconstruct Emperor Wu's appearance and identify genetic markers indicative of his physical characteristics. Despite the challenges posed by the degradation of the DNA samples, the team developed a novel approach tailored to handle highly fragmented genetic material, resulting in a tenfold improvement in data extraction.The analysis revealed that Emperor Wu likely had typical East Asian features, including dark hair, brown eyes, and intermediate to dark skin tone. Additionally, the study indicated that he may have been susceptible to various diseases, including stroke, gout, and leukemia, offering valuable insights into his health profile.Moreover, the genetic analysis provided intriguing clues about Emperor Wu's ancestry. While approximately 60% of his genetic makeup traced back to the Xianbei people, a nomadic group that founded the Northern Zhou dynasty, the remaining DNA resembled that of Han Chinese communities along the Yellow River. This suggests a complex ancestral lineage, reflecting the diverse cultural landscape of ancient China.The significance of this research extends beyond the individual case of Emperor Wu. By refining techniques for analyzing ancient DNA, researchers hope to unlock a deeper understanding of other historical figures and populations. The ability to reconstruct facial features and infer genetic traits from skeletal remains opens new avenues for studying ancient civilizations and their genetic legacies.In addition to shedding light on Emperor Wu's life and death, this study exemplifies the potential of genetic analysis to enrich our understanding of human history. By examining samples from different time periods and cultures, researchers aim to construct a comprehensive genetic lineage of East Asian populations, bridging the gap between past and present.Looking ahead, the research team plans to expand their investigations to include a broader range of ancient samples, with the ultimate goal of tracing the genetic origins of the Chinese nation. By unraveling the intricate tapestry of human genetics, they hope to illuminate the shared heritage of East Asian peoples and deepen our appreciation of the rich history of the region.In conclusion, the reconstruction of Emperor Wu's face and the insights gleaned from his genetic analysis represent a milestone in the study of ancient DNA. Through meticulous research and innovative methodologies, archaeologists and geneticists are unlocking the secrets of the past, offering new perspectives on the lives of historical figures and the evolution of human societies. As we continue to unravel the mysteries of our collective heritage, the story of Emperor Wu serves as a testament to the enduring quest for knowledge and understanding.

Defense NewsNew ZealandNew Zealand's first C-130J Super Hercules military transport aircraft has successfully completed its initial flight test in the United States. The demonstration flight lasted 246 minutes over Georgia and Alabama, covering a distance of approximately 990 kilometers (615 miles) and reaching an altitude of 10,500 feet (3,200 meters).This milestone comes after 18 months of construction by American defense contractor Lockheed Martin. The contract for the project, signed in 2019 under a foreign military sale with the US government, is valued at $1.4 billion. It includes five C-130Js, along with engines, spare parts, avionics, and communication systems.The new C-130Js will gradually replace New Zealand's aging C-130H Hercules systems, which have been in service for over five decades. The fleet will be stationed at the Royal New Zealand Air Force Base Auckland and operated by the agency's No. 40 Squadron.According to Air Force Chief Air Vice-Marshal Darryn Webb, the C-130J offers greater range, speed, and capacity compared to its predecessor, the C-130H. This modernization effort aims to enhance the interoperability between New Zealand and its closest defense partner, the Royal Australian Air Force.In addition to the aircraft acquisition, New Zealand has been investing in training facilities. Last year, the country completed the initial construction phase of a flight simulator for C-130J pilots in Auckland. Lockheed Martin also received a $38-million contract in 2022 to supply a separate system to train C-130J operators on the aircraft's weapon systems.The C-130J Super Hercules measures 34 meters (112 feet) in length, with a wingspan of 40 meters (131 feet). It is powered by 6-bladed propellers and four 4,637-horsepower turboprop engines, allowing for a maximum speed of 362 knots (670 kilometers/417 miles per hour) and reaching altitudes of up to 40,386 feet (12,310 meters). The aircraft is operated by three personnel and can carry up to 92 passengers.
