00:46 The mouse brain circuit controlling infanticidal behaviourIn mammals, infanticide is a relatively common behaviour, but not a default one. For example, virgin female mice will often kill young produced by other females, but this behaviour disappears when they become mothers themselves. To understand this switch, researchers have identified a brain circuit associated with infanticidal behaviour that gets switched off after mice give birth. They hope that by better understanding this circuit it could inform why animals engage in such behaviours.

08:11 Research HighlightsThe cyclone raging at the north pole of Uranus, and the ants that build landmarks to help them find their way home.
Research Highlight: A storm is whirling atop Uranus
Research Highlight: These hardy ants build their own landmarks in the desert
10:52 Getting to the source of fast solar windThe sun produces streams of plasma called solar wind that stretch out and provide a protective bubble around the solar system. However, despite decades of study, there’s much that isn’t known about how the Sun makes it. Now, a team has used data from the Parker Solar Probe and shown that the source of one sort of wind, known as ‘fast solar wind’, appears to be due to colliding magnetic fields that produce the huge amount of energy needed to fire plasma away from the Sun.

00:46 An AI that predicts gene interactionsMapping the network of genes that control cellular processes can be difficult to do when gene-expression data is sparse, such as in rare diseases or those affecting tissues that are hard to clinically sample. To overcome this, a team has developed an artificial intelligence system trained on a large, general dataset, and used it to make predictions about gene interactions in data-limited situations. As a test-case they look at the heart condition cardiomyopathy, and show that the system can identify potential interactions that could represent new therapeutic targets.

Shocked by the impact of online misinformation surrounding the COVID-19 pandemic, several researchers are launching efforts to survey scientists’ thinking on issues from vaccine safety to climate change. They hope that their projects will make scientific debate, and degrees of consensus, more visible and transparent, benefiting public conversation and policymaking. However, others suggest that these attempts might merely further politicize public debate.

00:45 Tree islands bring biodiversity benefits for oil-palm plantationGlobal demand for palm oil has resulted in huge expansion of the palm plantations needed to produce it, causing widespread tropical deforestation and species loss. To address this, researchers planted islands of native trees among the palms in a large plantation, and showed that this approach increases ecosystem health, without affecting crop yields. The team say that while protecting existing tropical rainforests should remain a priority, tree islands represent a promising way to restore ecosystems.

00:46 What JWST has revealed about an ancient galaxyResearchers have pointed the James Webb Space Telescope (JWST) at JD1, one of the universe's most distant known galaxies. The power of JWST has filled in some of the gaps in what was known about the galaxy, giving greater insight into its age, structure and composition. The team behind the work hope that learning more about how early galaxies like JD1 formed will help explain how the universe evolved into its present state.

12:34 How coral reef fish evolved to grow more quicklyFish that live in coral reefs are some of the fastest growing in the world, despite the environment they live in being relatively nutrient poor. This contradiction has long puzzled researchers, but now, a team has looked deep into the evolutionary history of the fish and discovered a critical point in time when they shifted towards faster growth, much earlier than was previously thought.

Many researchers have been critical of the biases that the publication process can introduce into science. For example, they argue that a focus on publishing interesting or significant results can give a false impression of what broader research is finding about a particular field.
To tackle this, some scientists have championed the publication of Registered Reports. These articles split the peer review process in two, first critically assessing the methodology of a research study before data is collected, and again when the results are found. The idea being to encourage robust research regardless of the outcome.
In this episode of Nature's Take we discuss Nature's recent adoption of the format, the pros and cons of Registered Reports, and what more needs to be done to tackle publication bias.
