White rhinos can learn about each other by sniffing one another's faeces.Many mammals communicate through smells in their urine. To see whether faeces have a similar role, Courtney Marneweck at the University of KwaZulu-Natal in Pietermaritzburg, South Africa, and her colleagues analysed odours from
The activation of a particular group of brain cells is all it takes to make mice hunt to kill.The brain's central amygdala has long been thought to have a role in producing emotions, particularly fear. To activate this brain region, Ivan de Araujo at
Born from astronomy, the study of planets is becoming increasingly geoscience. As divisions between disciplines continue to blur in Solar System studies, at Nature Geoscience we are looking forward to exciting joint projects with Nature Astronomy.
Organic carbon decomposition in anoxic marine sediments was thought to be dominated by bacteria, but experimental data and microbial culture studies now show that microalgae buried in coastal sands may also play an important role in carbon turnover.
180 million years ago Earth's continents were amalgamated into one supercontinent called Pangaea. Analysis of oceanic crust formed since that time suggests that the cooling rate of Earth was enhanced in the wake of Pangaea's dispersal.
Abrupt climate changes in the glacial North Atlantic altered the position of wind systems in the Northern Hemisphere and tropics. Ice-core data show that this disruption also reached the southern westerlies.
Fewer than a third of the 14,849 known protein families have at least one member with an experimentally determined structure. This leaves more than 5000 protein families with no structural – [Read More]
The Hippo growth control pathway coordinates cell proliferation, death, differentiation and stemness through regulatory phosphorylation of the YAP proto-oncoprotein, a major nuclear effector of Hippo signalling. In particular, YAP phosphorylation on Ser127 can promote inhibitory 14-3-3 interactions and cytoplasmic sequestration. Two studies in this issue of […]
Mutations in the APP and PSEN genes have provided direct evidence for the central role of aberrant amyloid β (Aβ) peptide production in familial Alzheimer's disease (AD). Newly identified risk factors will further help us to unravel how derailed physiological and cell biological processes lead to identical pathogenesis in late-onset AD (LOAD). Ubelmann […]
The emergence of barriers to reproduction between two populations is one of the most important features of speciation. Among the mechanisms of reproductive isolation are incompatible interactions between gene products of the parental species that reduce the fitness of hybrid individuals. The accumulation of such incompatibilities is described by the Bateson– […]
Pseudouridylation is a common post-transcriptional modification in RNA, but its functional consequences at the cellular level remain largely unknown. Using a proximity-biotinylation assay, we identified a protein module in mitochondrial RNA granules, platforms for post-transcriptional RNA modification and ribosome assembly, containing several proteins of unk […]

Grid-firing fields of neurons in the entorhinal cortex are thought to require inputs encoding running speed. Glutamatergic projections from the medial septum may be one of the inputs that provide these speed signals.
Recent studies reveal several groups of neurons that become activated upon anticipation or consumption of meals. These neurons constitute key components of the complex feedback system that prevents continuous feeding by mice.
An elegant study answers a long-standing question: how do correlations arise in large, highly interconnected networks of neurons? The answer represents a major step forward in our understanding of spiking networks in the brain.
I’m Roberto Isotti, a conservation photographer, Arkive and Wildscreen Exchange contributor and PhD in zoology. I’m based in Rome (where I was born). I began my professional activity in the Eternal City and even though I have travelled to six continents, I still maintain a deep connection with the city of Rome, that is forever […]
Our natural world is full of mystery and wonder and one of the most mysterious natural phenomenon of all is bioluminescence. We’ve just created a new topic page to celebrate and explore this amazing adaptation that some animals possess. Bioluminescence is the process by which living organisms produce their own light. Some organisms have organs […]
Wildscreen’s mission is to convene the best filmmakers and photographers with the most committed conservationists to create compelling stories about the natural world; that inspire the wider public to experience it, feel part of it and protect it. Films and photographs have an amazing power – they are able to transcend boundaries of language and […]
Today’s guest blog has been provided by ONCA, a UK-based charity which aims to cultivate environmental and social wellbeing through the arts. All their activities seek to inspire creativity and positive action in the face of environmental change, and to help galvanise the creation of a critical mass of work responding to and exploring these changes.
