What Artemis II’s astronauts will look for on the Moon’s far side Mission scientists spoke to Nature about the geological features they’re most excited for the crew to observe.

This Monday, 6 April, if all goes to plan, astronauts aboard NASA’s Artemis II mission will fly around the Moon’s far side. Nature talked to mission scientists about the geological features they're excited to see.

Investigating the replicability of the social and behavioural sciences - Nature A large-scale study on the replicability of claims from social and behavioural science journals reports that about half of the results replicate in the same patterns as the original study.

New article in Nature!

Happy to have contributed (as one of the many co-authors)

Researchers could replicate the results of about half of the studies in various social science disciplines

This holds for various fields: pol sci, econ, sociology, & psychology

Hallucinated citations are polluting the scientific literature. What can be done? Tens of thousands of publications from 2025 might include invalid references generated by AI, a Nature analysis suggests.

Sadly, not an April Fool & also not surprising. “An analysis conducted by @nature.com in collaboration with Grounded AI suggests that at least tens of thousands of 2025 publications, including journal papers, books, & conference proceedings, probably contain invalid references generated by AI.” 🧪

Oxytocin is much than a "social" hormone. I think it's more accurate to describe it as an allostatic hormone that helps maintain physiological stability. Its social effects are just a by-product of these regulatory efforts doi.org/10.1016/j.ti...

ABSTRACT

Spreadsheets are widely used software tools for data entry, storage, analysis, and visualization. Focusing on the data entry and storage aspects, this article offers practical recommendations for organizing spreadsheet data to reduce errors and ease later analyses. The basic principles are: be consistent, write dates like YYYY-MM-DD, do not leave any cells empty, put just one thing in a cell, organize the data as a single rectangle (with subjects as rows and variables as columns, and with a single header row), create a data dictionary, do not include calculations in the raw data files, do not use font color or highlighting as data, choose good names for things, make backups, use data validation to avoid data entry errors, and save the data in plain text files.

…reproducibility problems are widespread. Only one in three authors (35%) share code, and even when code is available, only every second main result (51%) is numerically reproducible.

Thanks, makes sense! But what I‘m not understanding is why Nature Medicine would not have held the authors to higher standards here? Nature Medicine seems like a serious journal; I would have expected reviewers would have taken issues with that. Would be disappointing, if it‘s just publication bias

How much does this impact the quality/credibility of the study in your eyes? I‘m interested as I‘m not familiar with this kind of research, and as a layperson, I would understand the stated reasons and trust the reputation of Nature Medicine

A screenshot of the article title: Reframing oxytocin as a behavioral flexibility hormone

Scientific claims in biobehavioral oxytocin research are dependent on a “derivation chain”. Theoretical models are the beginning of this chain, which are dependent on a theoretical core supported by auxiliary hypotheses. Efforts to improve biobehavioral oxytocin research have tended to focus on auxiliary hypotheses related to experimental models (e.g., improving oxytocin delivery to the brain, polygenic approaches for genetics studies), and statistical auxiliary hypothesis (e.g., appropriate sample sizes for research). However, even if these issues are addressed, a poorly specified theoretical core (and associated auxiliary hypothesis) can lead to unreliable scientific claims

Oxytocin is typically described as a "social" hormone. In our new article, we propose that it should instead be viewed a hormone that modulates behavioral flexibility

198 effect sizes in ego depletion resesrch showed an effect size of d=0.62. Preregistered large replications (including some by original authors) yielded an effect size of 0. No one has been able to offer any other explanation for this huge research waste than massive p-hacking.

Brains learn structure without reward, instruction, or feedback — a process called statistical learning.

Human infants do this effortlessly (famous work by Saffran et al 1996), but how does the brain implement it?

A figure depicting continental drift from when Gondwana existed to present day, with continents and countries colored according to the ratite species that occur or occurred on them. Next to that is a cartoon of a phylogeny that we would expect support for if continental drift explained patterns of species occurrence and relatedness. And next to that is a cartoon of the phylogeny supported by the genetic data presented in this paper, which demonstrates that closely related species must have traveled great distances after Gondwana broke up, after which flightlessness evolved, and that this happened more than once.

This paper is a great for teaching phylogenetic trees.

Clearly written. It discusses hypotheses of relatedness among species via continental drift vs genetic data. 🧪

Illustration of the hypothesized flows of information between perception, memory and cognitive control in a conceptual model of working memory. Stimuli attributes are processed to varying degrees of abstraction and parts of these representations can be loaded into working memory under the guidance of cognitive control. Familiar stimuli such as the letter B activate visually abstract representations while less familiar stimuli are limited to sensory representations. Information can be shifted both up and down levels of the perceptual hierarchy to build either more or less abstract representations of either perceived or imagined stimuli. Working memories can be shifted into or out of the hierarchy as needed.
