Northern Afghanistan experienced a 6.3-magnitude earthquake near Mazar-e-Sharif, causing extensive damage and at least 20 deaths, with over 320 injuries reported. The quake also damaged the 15th-century Blue Mosque, a cultural landmark. USGS stated its depth was 28 km, and tremors were felt as far as Kabul. This marks yet another tragedy in a region frequently struck by earthquakes, exacerbated by poor infrastructure and limited disaster response capabilities. Historical data indicates that Afghanistan has faced 12 earthquakes above magnitude 7 since 1900, highlighting its vulnerability. Analysts suggest increased international aid and reconstruction efforts are imperative to mitigate the humanitarian impact. However, post-earthquake assistance remains slow, with the UN estimating $111.5 million required for recovery. The Taliban’s governance challenges and limited global recognition further hinder coordinated relief operations. Source 1 Source 7 Source 9 Source 36 Source 39 Source 40

New research from Frontiers in Marine Science reveals orcas in Mexico’s Gulf of California are targeting juvenile great white sharks using sophisticated hunting techniques, including flipping sharks to induce tonic immobility. This behavior, previously observed off South Africa, underscores the orcas' intelligence and adaptability. Scientists suggest the orcas' preference for nutrient-rich shark livers may be linked to environmental changes, such as warming waters pushing shark nurseries closer to predator territories. This discovery raises concerns about ecological balance and the disruption of shark populations. Conservationists recommend identifying critical habitats for orcas and sharks to develop protective measures. Source 12 Source 21

A study by Japan’s Keio University measured the cosmic microwave background radiation temperature from seven billion years ago, confirming it was 5.13 K above absolute zero, double today's temperature. This precise finding supports Big Bang theory predictions that the universe cools as it expands. Researchers used data from the ALMA observatory, analyzing light from distant quasars. These results reinforce the reliability of cosmological models, but debates persist over the implications for dark energy and the universe's ultimate fate. The study provides a crucial "middle chapter" in the universe’s evolution, bridging gaps in our understanding of cosmic history. Source 25

Research from King’s College London reveals that previously considered ‘junk DNA’, specifically transposable elements (TEs), can be weaponized to target drug-resistant blood cancers. The study highlights how mutations in genes like ASXL1 reactivate TEs, causing cellular stress in cancer cells. PARP inhibitors, drugs already used in other cancers, can exploit this vulnerability, selectively killing cancerous cells while sparing healthy ones. This breakthrough offers hope for treating otherwise intractable cancers. However, experts caution that clinical trials are needed to validate the findings. The research reflects a growing trend of uncovering new roles for non-coding DNA, challenging past assumptions about its redundancy. Source 26

The interstellar comet 3I/ATLAS, only the third of its kind observed, is exhibiting unusual brightening patterns as it approaches the Sun. Observed by solar-monitoring satellites, its brightness increased at twice the typical rate, suggesting unique surface activity. Its blue hue, attributed to gas emissions, contrasts with earlier observations of reddish dust. Scientists theorize its behavior could result from its composition or interstellar journey. The comet offers valuable insights into the characteristics of objects beyond our solar system. Researchers emphasize the importance of continued monitoring to understand its anomalies and broader implications for interstellar studies. Source 27

A meteorite may have struck a Tesla in South Australia, potentially marking the first instance of a meteorite hitting a moving vehicle. The South Australian Museum is investigating the incident, examining melted glass and embedded particles in the car’s windshield. If confirmed, this event underscores the rarity of such occurrences, given the vast amounts of space debris that rarely reach Earth's surface intact. While alternative explanations like space junk are being considered, experts highlight the importance of studying these phenomena to better understand the risks posed by cosmic debris. Source 24

The Drinking Water Inspectorate in the UK has flagged elevated levels of PFAS, or “forever chemicals,” in water sources serving over six million people. These chemicals, linked to health risks including cancer, are challenging to remove from water supplies, with Water UK calling for stricter regulations on PFAS production. Environmentalists argue that current UK limits are too lenient compared to US standards. While water companies implement advanced treatments, such measures are costly and energy-intensive, raising questions about funding and sustainability. The government faces pressure to legislate stricter PFAS controls as public health concerns grow. Source 28

A UK study involving 85,000 participants reveals that men must exercise twice as much as women to achieve similar reductions in heart disease risk. Women’s higher estrogen levels and more efficient muscle fibers may account for this disparity. The findings challenge sex-neutral exercise guidelines, suggesting tailored recommendations could improve outcomes. While this highlights biological differences, experts emphasize that both genders benefit significantly from physical activity. The study reignites discussions about personalized health interventions, particularly as cardiovascular disease remains a leading global cause of mortality. Source 32

South Korea and China have signed a content exchange deal, allowing K-pop to re-enter the Chinese market after a seven-year unofficial ban. Stocks of major entertainment companies like SM Entertainment surged following the announcement. The agreement signals a thaw in cultural relations, possibly tied to broader diplomatic efforts under President Lee Jae Myung and President Xi Jinping. Analysts view this as a win-win, boosting South Korea’s cultural exports while enhancing China’s soft power. However, skepticism remains about the long-term stability of such agreements amid ongoing geopolitical tensions. Source 10

Documents obtained by the BBC reveal that Sheffield Hallam University suspended research into Uyghur forced labor under pressure from China’s National Security Service. The university cited risks to its operations in China and staff safety, sparking criticism for prioritizing financial interests over academic integrity. Professor Laura Murphy, whose work was affected, has since resumed her research following an apology. This case underscores the challenges of balancing academic freedom with geopolitical pressures, particularly as universities become increasingly reliant on international student income. Policymakers face calls to strengthen protections for academic independence. Source 8
