The Vera Rubin Has Found Two More of the Milky Way's Dim Satellites

The Vera Rubin Observatory has detected two more of the Milky Ways' dim, hard to see satellites. One is an ultra-faint dwarf galaxy, and one is a globular cluster. Each one is a missing piece of the puzzle in the Milky Way's merger history. By finding more of these satellites, our understanding of galaxy growth, and the role dark matter plays in it, will improve.

Queen's University Belfast students find Neptune's elusive Trojan asteroids

An international team led by researchers at Queen's University Belfast has made a discovery that has eluded astronomers for decades. Beginning in 1906, telescope observations revealed a population of asteroids leading and trailing Jupiter, which came to be known as the "Trojan" and "Greek" populations. Since then, astronomers have discovered similar "families" orbiting Saturn and Uranus, but not Neptune. Thanks to the Queen's-led team, the mystery of the missing Trojans has now been resolved.

Chinese writing developed square forms gradually, shaped by language, tools and tradition, analysis suggests

A new historical analysis challenges the received wisdom as to why Chinese characters developed their distinctive square shapes. The work, published in the International Journal of Arts and Technology, argues that their shape resulted from interacting linguistic, technological and cultural factors rather than a single cause.

Climate change is making the tropics hotter

A new study finds that tropical areas often thought to be safe from the effects of climate change are actually experiencing significant changes in rainfall and extreme temperature events. The paper, "Shifting climate in Caribbean tropical forests: Long-term trends at La Selva (Costa Rica) and El Verde (Puerto Rico)," is published in PLOS Climate.

Ceres' water ice can mask massive surface salt deposits

The dwarf planet Ceres is arguably one of the most overlooked and underappreciated planetary objects in the solar system. This could be because while Ceres has the same dwarf planet designation as Pluto, Ceres is largely considered an "asteroid" since it resides in the main asteroid belt. However, along with being the largest object in the main asteroid belt, Ceres accounts for between 25% and 30% of the belt's total mass.

OpenAI CEO 奥尔特曼称个人电脑浪费内存遭全网声讨，马斯克也来补刀

IT之家 11 月 2 日消息，萨姆 · 奥尔特曼近期关于内存的言论引发越来越多人反对，埃隆 · 马斯克也加入了这场声讨。 上周，这位 OpenAI 首席执行官的一番话在全网、尤其是玩家群体中引发强烈不满。他称，人们把内存装在个人电脑里，而不是放在数据中心，是一件“很糟糕”的事。 在和博主 Cheeky Pint 的访谈中，奥尔特曼说：“从全球资源分配角度来看，所有人都把全球有限的 DRAM 资源放在自家电脑里，而内存大部分时间利用率只有 5%，这其实非常糟糕。在供给紧张的大环境下，资源放在云端才能实现利用率最大化。可很多人的直觉恰恰相反。” 这番言论遭到大量嘲讽。不少人认为，无论他本意如何，听起来像是想剥夺个人对内存的所有权，迫使全社会把资源交给 OpenAI 这类 AI 企业使用。社交媒体上充斥着批评帖、表情包和短视频，大家纷纷表态要守住自己的内存。也有大量玩梗内容，无数表情包、AI 生成视频调侃这位 AI 富豪。 说到 AI 富豪，他的行业对手马斯克也发了一张表情包表态，向数千万粉丝亮出自己在内存所有权这件事上的立场。 马斯克在自己旗下的 X 平台发文：“民众也理应拥有属于自己的内存！”配图是昆汀 2009 年电影《无耻混蛋》里的汉斯 · 兰达上校。 马斯克还在回复网友的评论时，称奥尔特曼是个“智障”。 AI 热潮推高了内存需求，内存供给紧张，显卡、游戏主机、电脑配件价格一路
