Ancient humans in South America used complex funeral rituals and manipulated the bodies of their dead as early as 10,000 years ago.André Strauss at the University of Tübingen in Germany and his colleagues analysed bones from 26 human burials, discovered during 15 years of
Bismuth crystals can act as superconductors — but only at temperatures approaching absolute zero.Researchers have long been searching for new superconducting materials, which have the ability to maintain an electric current with no power source. A team led by Srinivasan Ramakrishnan at the Tata
The Intergovernmental Panel on Climate Change is preparing a report on keeping global warming below 1.5 °C. How the panel chooses to deal with the option of solar geoengineering will test the integrity of scientific climate policy advice.
The latitude of the tropical rainbelt is constrained by the energy balance between hemispheres. An expansion of this theory that includes longitudinal variations of atmospheric heating can predict regional changes in tropical precipitation.
Mantle enrichment processes were thought to be limited to parts of oceanic plates influenced by plumes and to continental interiors. Analyses of mantle fragments of the Pacific Plate suggest that such enrichment processes may operate everywhere.
The centrosome is crucial for neuronal migration and polarisation, processes that are disrupted in a number of neurodevelopmental disorders including schizophrenia. Mutation of DISC1, associated with increased risk of schizophrenia and psychiatric illness, has been shown to affect the centrosome, but the mechanisms involved have not been elucidated. In this […]
Poly(ADP-ribosyl)ation, or PARylation, was first described over 50 years ago. Since then, our understanding of the biochemistry and enzymology of this protein modification has significantly progressed. PARylation has long been associated with DNA damage and DNA repair as well as genotoxic stress , . However, over the last two decades this has expanded […]
Stem cells have the remarkable ability to undergo proliferative symmetric divisions and self-renewing asymmetric divisions. Balancing of the two modes of division sustains tissue morphogenesis and homeostasis. Asymmetric divisions of Drosophila neuroblasts (NBs) and sensory organ precursor (SOP) cells served as prototypes to learn what we consider now princi […]

Neuroscientists dedicate themselves to understanding the brain. But what happens when they disagree on experimental outcomes, data interpretation or methodology? Nature Neuroscience debuts a format that invites researchers to debate critical issues in neuroscience.
Intellectual disabilities and associated neurodevelopmental disorders may result from rare genetic mutations. Ganna et al. show that these also help explain variability in educational attainment, a proxy for cognitive function.
During synaptic activation, the function of astrocyte endfeet depends on the vascular target: at the capillary, but not at the arteriole, a newly described P2X1R–phospholipase D2 pathway modulates prostaglandin E2 release and vessel dilation.
Humans and animals can collect and maintain information that guides decisions, but how neural circuits achieve this is unknown. It seems neural populations may do so by passing through diverse states in many possible sequences.
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. […]
Wildscreen recently worked with world-renowned street artist Louis Masai to create two beautiful murals in our hometown of Bristol, UK to mark the beginning of the Wildscreen Festival and raise awareness of two little-known endangered species. This painting event was part of Wildscreen’s Witness the Wild programme, a series of free-to-attend events from 21/0 […]
Vanishing Kings – Lions of the Namib is a film created by Will and Lianne Steenkamp that has been nominated for a 2016 Panda Award for Cinematography (Small Crew). We were still on a high from the amount of hard work that the public and conservation organisations had put into raising awareness of World Lion Day on 10 […]
