A | While scientists are still to determine whether some extraterrestrial civilization may exist somewhere out there in the universe, one astronomer points out that we apparently don’t have a plan for a yet-hypothetical situation where aliens actually reach out to us.,According to the Daily Star, prominent popular scientist and Australia’s Astronomer at Large Fred Watson pointed out that scientists do have a checklist to establish whether a communication attempt by aliens is genuine, but don’t have a plan for actually establishing contact with them.,“There’s a well-established chain of boxes that need to be ticked and it would go through a lot of analysis to ensure that what you’re talking about is a real phenomenon,” he said. “However, once scientists identified what had happened, it’d then be up to the political leaders of the world to decide what to do about it, and as far as I’m aware, there’s no plan in place.”,Burnout or Homeostasis: Researchers Explain Why Aliens Are Yet to Come Knocking at Earth's Door20 June, 13:15 GMT,He did note, however, that there is a rather “gloomy outlook about there being intelligent life forms” out there in space, with the “overwhelming opinion” being that “microbial life might exist.”,“The common view is we are just a complete freak of nature – intelligent life is so rare and is such an unlikely event," Watson remarked.。 7月22日，据财闻海外资讯，三星电子、SK海力士（SKHY.US）与美光科技（MU.US）三大存储芯片厂商全面展开HBM4良率竞争。作为第六代高带宽内存，HBM4将应用于英伟达（NVDA.US）下半年推出的Vera Rubin等AI加速芯片，成为下半年企业业绩关键支撑。 三星已率先实现HBM4规模化量产，业内预估其良率接近70%，得益于1C工艺DRAM（年初良率稳定超80%）的持续带动，良率管控能力显著提升。 SK海力士虽未公布精确良率，但行业判断其已进入稳定区间。为巩固超半HBM市场份额，其正洽谈引进新生产设备，以优化工艺并扩大产能。 美光因产能基础相对薄弱，正加速推进良率爬坡与大规模设备投资，同步提升产出能力。 良率（合格芯片占比）直接决定交付量与盈利空间，是厂商攻坚核心。尽管此前通用DRAM短期利润反超，但其涨价空间已趋缓（一季度近翻倍、二季度30%–50%、三季度0%–20%），而HBM需求持续扩张、高毛利优势将重归主导。
