Technology News ,Medical science :- Scientists from MIT and Harvard have discovered a more effective way to correct genetic mistakes using tiny, virus-like particles. These particles, called engineered virus-like particles (eVLPs), carry prime editors into mouse cells with great success, fixing genetic disorders.Prime editing is a powerful technique for fixing genetic mutations that cause diseases. The researchers improved the editing process in human cells by 170 times by modifying these eVLPs. In tests on mice with genetic eye problems, they corrected mistakes and partially restored their vision.The breakthrough is seen as a promising treatment for genetic disorders in living animals. Importantly, when the same method was used to edit genes in the mouse brain, there were no unintended changes. This study marks the first time that therapeutic prime editing has been successfully delivered in an animal using protein-RNA complexes, according to David Liu, the senior author of the study.Scientists have been exploring gene editing to address genetic issues causing diseases. Prime editing, introduced in 2019, allows precise and diverse changes in DNA. However, delivering this editing system into living animal cells has been challenging.Different methods have been used, including lipid nanoparticles and viruses, with virus-like particles (VLPs) showing promise. VLPs are made of viral proteins and carry cargo but do not contain viral genetic material. Although VLPs have had some success, they require specific engineering for each cargo type.In their study, Liu and his team used their system to fix two different genetic problems in the eyes of mice. One issue causes a disease called retinitis pigmentosa, leading to gradual vision loss, and the other is linked to blindness in a condition called Leber congenital amaurosis (LCA) in humans.Using their eVLPs, they corrected the mutations in about 20 percent of the animals" retina cells, partially restoring their vision. The researchers made improvements to how the prime editing cargo was packaged, separated from the delivery vehicle, and entered the target cells" nuclei. These coordinated enhancements led to a 100-fold increase in efficiency, making the technique potentially suitable for therapeutic use in animals."This kind of improvement in efficiency should be enough to give us therapeutically relevant levels of prime editing," said Liu. "But we did not know for sure until we tested it in animals."

Defense News ,China :- In a recent move, the People Republic of China has imposed sanctions on five prominent US defense contractors, responding to their involvement in arms sales to Taiwan. The decision, as disclosed by the Chinese Ministry of Foreign Affairs, names BAE Systems Land and Armaments, AeroVironment, Viasat, Alliant Techsystems Operation, and Data Link Solutions.The crux of China argument lies in the assertion that these sales circumvent Chinese authority, thereby posing a perceived threat to the nation security and sovereignty. This has prompted the freezing of both movable and immovable properties owned by these companies in China, accompanied by a prohibition on any interactions between organizations, individuals, and the sanctioned businesses.According to the foreign ministry, the arms sales to Taiwan disrupt peace and stability in the Taiwan Strait, infringing upon the legitimate rights and interests of Chinese entities. The ministry expressed strong disapproval, stating that solemn démarches have been conveyed to the US.In the official statement, the agency reiterated China unwavering territorial sovereignty over Taiwan, emphasizing the need for Washington to acknowledge their standing relationship with Beijing on this matter. The ministry urged the United States to adhere to the one-China principle and the three China-US joint communiqués, along with observing international law and basic norms governing international relations. The call was clear: cease arming Taiwan and refrain from targeting China with illegal unilateral sanctions; otherwise, a strong and resolute response from China was indicated.The diplomatic tension is not new, with the recent sanctions being a response to the continuous stream of US arms sales to Taiwan. The US State Department approved a $300-million sale of military information system equipment to Taiwan in the past month, and in August 2023, Washington cleared Taipei purchase of advanced airborne tracking sensors for its F-16 Fighting Falcon combat jets. The US also announced plans to approve a separate $440-million contract to Taiwan in June, aimed at bolstering the country ammunition and repair parts for weapons and vehicles. These transactions follow earlier deals, such as the $180-million sale of vehicle-launched anti-tank systems to Taipei in 2022 and a significant $1.1-billion military sale in the same year to enhance Taiwan surveillance and air defense capabilities.As the diplomatic dance between China and the United States unfolds, the stakes continue to rise, and the global community watches with bated breath for any signs of de-escalation or further escalation in this ongoing geopolitical saga.

Defense News ,South & North Korea :- In a recent development, Kim Yo Jong, the influential sister of North Korean leader Kim Jong Un, ridiculed South Korea ability to detect weapons launches and dismissed Seoul claim that North Korea fired artillery shells into the sea. This incident unfolded as South Korea military swiftly labeled her statement as "low-level psychological warfare" and issued a stern warning of a robust response to any provocations from North Korea.South Korea military had reported that North Korea fired shells near the disputed western sea boundary for the second consecutive day, launching over 60 rounds on Saturday following more than 200 shells the day before. Contrary to these claims, Kim Yo Jong asserted on Sunday that North Korea had only detonated blasting powder to test South Korea military detection capabilities, suggesting that their response had been a misjudgment.Kim Yo Jong criticized the South Korean people, expressing pity for entrusting their security to what she described as "blind persons" and labeling the military as "gangsters" and "clowns in military uniforms." She even went so far as to suggest that miscalculations by the South Korean military could lead to accidental clashes, jeopardizing the safety of Seoul, a city with 10 million residents just an hour drive from the land border.In response, South Korea Joint Chiefs of Staff emphasized their close monitoring of North Korean military activities and urged North Korea to cease actions escalating tensions. They warned of an overwhelming reaction if provocations persisted.Tensions between the two Koreas have heightened due to North Korea continuous missile tests since 2022 and South Korea expanded military training with the United States. Both countries engaged in artillery firings on Friday, violating a 2018 military agreement intended to ease tensions along their border. This agreement, designed to halt live-fire exercises and aerial surveillance, now faces the risk of collapse.Experts speculate that Kim Jong Un may escalate weapons tests leading up to South Korea parliamentary elections in April and the U.S. presidential elections in November. The belief is that a bolstered weapons arsenal would strengthen North Korea position for future diplomatic negotiations, seeking greater concessions from the United States.

Defense News , China & Taiwan :- In the lead-up to Taiwan crucial presidential and parliamentary elections on January 13, the country defense ministry has accused China of engaging in activities that pose threats to aviation safety and psychological warfare against the Taiwanese people. Recent sightings of balloons near or over the island have raised concerns, prompting Taiwan to heighten its alert level.The issue of using balloons for potential spying gained global attention in February when the United States claimed to have shot down a Chinese surveillance balloon. China countered, asserting that the balloon was a civilian craft that had unintentionally drifted off course.Taiwan remains on high alert, alleging that China is applying both military and economic pressure in an attempt to interfere with the upcoming elections. The fundamental disagreement lies in China viewing Taiwan as its own territory, a claim vehemently rejected by Taiwan government.Over the past month, Taiwan defense ministry has reported multiple instances of Chinese balloons flying over the sensitive Taiwan Strait. In the past week alone, some balloons were observed flying over Taiwan island, particularly near major air bases, intensifying concerns.In an official statement, Taiwan defense ministry declared the balloons to be a "serious threat" to international aviation safety, given their flight paths. The ministry accused China of employing "grey zone" tactics, characterizing the balloons as part of cognitive warfare aimed at affecting the morale of the Taiwanese people.Contrary to earlier assertions that the balloons were primarily for weather monitoring, the defense ministry now emphasizes the potential threat posed by China actions. China Taiwan Affairs Office dismissed these concerns, attributing them to the ruling Democratic Progressive Party efforts to magnify threats from the mainland for electoral gains.Taiwan Vice President Lai Ching-te, who is also the presidential candidate for the Democratic Progressive Party, accused China of utilizing warships, warplanes, and fake news to "divide Taiwan." Urging voters to use their ballots to champion democracy and freedom, Lai emphasized Taiwan resilience against authoritarian regimes.In a stronger-worded statement, Taiwan defense ministry disclosed that it had detected two additional Chinese balloons within the past 24 hours, one of which briefly flew over the far northern tip of the island.Amid escalating tensions, the United States, a key supporter and arms supplier to Taiwan, expressed concern over the rising semiconductor powerhouse island. White House national security spokesman John Kirby, however, refrained from commenting on the balloon issue directly, emphasizing the U.S. support for free, fair, and transparent elections in Taiwan.As accusations and tensions persist, China message to Taiwan appears clear - a subtle pre-election warning that reinforces their vigilance and surveillance capabilities. The situation underscores the delicate balance between the two nations and the potential for external interference in Taiwan democratic process.

Defense News ,India & UK :- In a pivotal move for India-UK relations, Defence Minister Rajnath Singh is set to embark on a three-day visit to the United Kingdom, marking the first ministerial-level visit in the defence sector in 22 years. Originally planned for June 2022, the anticipation surrounding this tour has grown due to its cancellation earlier for "protocol reasons."During his visit, Singh is scheduled for extensive discussions with his UK counterpart, Defence Secretary Grant Shapps. The itinerary also includes inspecting a ceremonial Guard of Honour, paying homage to Mahatma Gandhi and Dr B.R. Ambedkar memorials in London, and engaging with the Indian diaspora in the UK.Rahul Roy-Chaudhury, Senior Fellow at the International Institute for Strategic Studies, emphasizes the significance of this visit, stating that it reflects an enhancement in India political relationship and trust-building with the UK since British Prime Minister Rishi Sunak visit to India for the G20 Summit in September the previous year.Roy-Chaudhury highlights the substantive goals of the visit, aiming to deepen military cooperation and defence industrial partnerships. This includes building on the November 2023 Defence Consultative Group meeting in Delhi and the inaugural 2+2 Foreign and Defence Dialogue in October 2023.While the UK is not currently among India top five strategic partners, the visit holds promise for strengthening the India-UK defence technological and industrial partnership. Ongoing projects with Rolls-Royce, GE (Naval) UK, and MBDA (UK) in aero-engines, naval electric propulsion, and ground-based air defence systems could see significant progress.The visit occurs amid concerns about pro-Khalistan violence in the UK and unresolved legacy issues regarding UK defence supplies to India. However, analysts suggest that the ministerial dialogue provides an opportunity to focus on operationalizing the Make in India and Atmanirbhar Bharat agenda in the defence sector.The trajectory of the India-UK defence partnership was set during former Prime Minister Boris Johnson visit to India in April 2022, where he announced the creation of an Open General Export Licence for India. This move aims to reduce bureaucracy and streamline defence procurement processes.With both India and the UK heading towards general elections, the visit gains added significance. It coincides with accelerated negotiations for a free trade agreement, projected to significantly boost the current GBP 36-billion bilateral partnership. As the curtains rise on this crucial diplomatic interaction, the prospects for renewed vigour in defence cooperation between India and the UK look promising.
