Holographic wormhole

全息虫洞

One challenge that stems from the fundamental incompatibility between general relativity and quantum mechanics is that there is no consensus on a theory of quantum gravity. A way to potentially overcome this is through the holographic principle, which says that a system involving gravity can be described by a lower-dimensional quantum system. In this week’s issue, Maria Spiropulu and her colleagues replicate the dynamics of a traversable holographic wormhole by experimentally realizing the corresponding quantum dynamics in a quantum computer using 9-qubits. This is an early step towards studying theories of quantum gravity in the laboratory. In the same quantum chip, the researchers created two entangled quantum systems. They inserted a qubit into one of them and observed the information emerging from the other exhibiting the expected gravitational properties of the traversable wormhole.

广义相对论和量子力学之间的根本不相容所带来的一个挑战是,对于量子引力理论还没有达成共识。一种可能克服这一问题的方法是通过全息原理,该原理表明涉及引力的系统可以用低维量子系统来描述。在本周的期刊中,Maria Spiropulu和她的同事通过使用9量子位在量子计算机中通过实验实现相应的量子动力学来复制可穿越全息虫洞的动力学。这是在实验室研究量子引力理论的早期步骤。在同一个量子芯片中,研究人员创建了两个纠缠的量子系统。他们将一个量子位插入其中一个,并观察从另一个出现的信息,这些信息展示了可穿越虫洞的预期引力特性。
失落的世界

The cover shows an artist’s impression of the rich ecosystem that existed in parts of northern Greenland some 2 million years ago. The ecosystem is reconstructed from ancient DNA in this week’s issue by Eske Willerslev and colleagues. Working at the Kap København Formation in Peary Land, the researchers gathered sediment samples rich in organic material from 5 different geological sites. By extracting and sequencing DNA from these samples, they were able to piece together a picture of the flora and fauna present around 2 million years ago. The team found evidence of open boreal forest mixed with Arctic species such as cedar, spruce and birch, as well as signs of animals including hares, mastodons, reindeer and geese. The evidence affirms that this part of Greenland, now a polar desert, was 11–17 °C warmer than it is today and suggests it was home to an ecosystem composition that no longer exists anywhere in the world.

封面展示了一位艺术家对大约200万年前格陵兰岛北部部分地区存在的丰富生态系统的印象。Eske Willerslev 及其同事在本周的一期杂志中根据古代DNA重建了生态系统。在Peary Land的Kap København地层工作,研究人员从 5 个不同的地质地点收集了富含有机物质的沉积物样本。通过从这些样本中提取DNA并对其进行测序,他们能够拼凑出大约200万年前存在的动植物群的图片。该团队发现了开放的北方森林与雪松、云杉和桦树等北极物种混合的证据,以及野兔、乳齿象、驯鹿和鹅等动物的迹象。证据证实,格陵兰岛的这一部分现在是极地沙漠,比现在温度高11-17 °C,并表明它是世界上任何地方都不再存在的生态系统组成的家园。
蚂蚁牛奶

The cover shows clonal raider ants (Ooceraea biroi) tending to pupae and small larvae. Ants are social insects, and their colonies are complex biological systems with sophisticated communication, behaviour and cooperation. In this week’s issue, Daniel Kronauer and his colleagues reveal previously unnoticed social behaviour involving the immobile pupal stage in the insects’ life cycle. The researchers found that, just before hatching, the pupae secrete a nutrient-rich moulting fluid that is analogous to mammalian milk. This fluid is rapidly consumed by adult ants and young larvae, which the adults place on the pupae. The team notes that larvae unable to access the fluid show stunted growth and have a poor survival rate. Similarly, if the secretions aren’t removed from the pupae, they get fungal infections and die. The researchers also find that the fluid contains hormones and psychoactive substances that might influence the physiology and behaviour of the overall colony.

封面展示了克隆入侵者蚂蚁(Ooceraea biroi)正在孵化蛹和小幼虫。蚂蚁是社会性昆虫,它们的蚁群是复杂的生物系统,具有复杂的交流、行为和合作。在本周的期刊中,Daniel Kronauer和他的同事揭示了以前未被注意到的社会行为,这些行为涉及昆虫生命周期中不动的蛹阶段。研究人员发现,就在孵化之前,蛹会分泌一种营养丰富的蜕皮液,类似于哺乳动物的乳汁。这种液体会被成年蚂蚁和幼虫迅速消耗掉,然后被成年蚂蚁放在蛹上。该团队指出,无法接触液体的幼虫生长发育迟缓,存活率很低。同样,如果不从蛹中清除分泌物,它们就会感染真菌并死亡。研究人员还发现,液体中含有激素和精神活性物质,可能会影响整个群落的生理和行为。
一年。十个故事。

As 2022 enters its final weeks, we look back on the past 12 months through the lens of Nature’s 10 — ten people who helped to shape science during the year. The cover takes its inspiration from the stunning images that have so far emerged from the James Webb Space Telescope. Launched on Christmas Day 2021, the telescope sent its first image back to Earth this summer and has since provided astronomers with views of the Universe in unprecedented detail.

随着2022年进入最后几周,我们通过《自然》杂志的10位人物——在这一年帮助塑造科学的十位人物——的镜头回顾过去12个月。封面的灵感来自詹姆斯·韦伯太空望远镜迄今出现的令人惊叹的图像。该望远镜于2021年圣诞节发射升空,今年夏天将其第一张图像发回地球,此后以前所未有的细节为天文学家提供了宇宙景观。
