Modelling how ocean currents spread the larvae of coral-eating starfish around Australia's Great Barrier Reef can help to identify areas that are prone to damaging epidemics of the pest.A team led by Karlo Hock of the University of Queensland in St Lucia, Australia, used
The recent, mysterious expansion of Antarctic ice could be overestimated because of a data-analysis error, according to US scientists.Ian Eisenman at the Scripps Institution of Oceanography in La Jolla, California, and his colleagues found the mistake when they compared two versions of satellite data
A sponge-like device absorbs water and solar energy to generate steam efficiently (pictured).Gang Chen at the Massachusetts Institute of Technology in Cambridge and his colleagues placed a layer of graphite flakes on top of a piece of carbon foam. The foam floats
Southwest Australia has become increasingly dry over the past century. Simulations with a high-resolution global climate model show that this trend is linked to greenhouse gas emissions and ozone depletion — and that it is likely to continue.
Sandstone arches and other striking landforms are the showpieces of national parks around the globe. Experiments and numerical analyses show that they result from a self-organization process that involves vertical load, wind erosion and grain locking.
Most researchers today believe that each finger forms because of its unique position within the early limb bud. However, 30 years ago, developmental biologists proposed that the arrangement – [Read More]
Autophagy is the main cellular catabolic process responsible for degrading organelles and large protein aggregates. It is initiated by the formation of a unique membrane structure, the phagophore, which engulfs part of the cytoplasm and forms a double-membrane vesicle termed the autophagosome. Fusion of the outer autophagosomal membrane with the lysosome and […]
How to attenuate traumatic memories has long been the focus of intensive research efforts, as traumatic memories are extremely persistent and heavily impinge on the quality of life. Despite the fact that traumatic memories are often not readily amenable to immediate intervention, surprisingly few studies have investigated treatment options for remote traumat […]
Does cell-to-cell spreading of misfolded proteins occur in all neurodegenerative disorders? A study in this issue of Nature Neuroscience now demonstrates propagation of mutant huntingtin in brain slice cultures and in vivo, thereby extending the process of cell-to-cell propagation of misfolded proteins to Huntington's disease.
Molecular orchestration mediated by Fezf2, a master transcriptional regulator of a particular type of cortical neurons, directly determines both their identity and axonal routing, and thus their connectivity.
Denise Spaan is the Field Station Coordinator and Conservation Education Manager for The Little Fireface Project which was set up to help protect the slow loris in Indonesia. We caught up with Denise to ask her more about this fascinating species and the important work being done to conserve it. How did you get into […]

Species: Mountain nyala (Tragelaphus buxtoni) Status: Endangered (EN) Interesting Fact: The male mountain nyala is larger than the female, and has long, spiralling horns, which may grow to 118 centimetres long. As the male matures, the tips of its horns develop an ivory colouration. More information: The mountain nyala is an elegant and rather attractively [ […]
Birdlife’s recent assessment of 350 newly recognised bird species, on behalf of the IUCN Red List, has found that 25 percent of these species are at risk of extinction. Around 13 percent of all known bird species are considered to be at risk, showing that the conservation of these newly recognised species needs to be […]
