A marine mollusc has hundreds of eyes in its armour that can see images.Christine Ortiz at the Massachusetts Institute of Technology in Cambridge and her colleagues studied the structural, optical and mechanical properties of the eyes of Acanthopleura granulata (pictured) using various experimental
Some weight-loss surgeries can diminish cravings for sweets by altering the brain's response to the neurotransmitter dopamine.Ivan de Araujo of Yale University in New Haven, Connecticut, and his colleagues studied the effects of a duodenal–jejunal bypass, which reroutes food from the stomach directly into
In the United States, hurricanes have been causing more and more economic damage. A reanalysis of the disaster database using a statistical method that accounts for improvements in resilience opens the possibility that climate change has played a role.
Little is known about the mechanisms that destroy the oldest organic molecules found in seawater. Field and laboratory observations suggest that these molecules are destroyed by the heat and pressure of deep-sea hydrothermal systems.
Ice streams transport ice rapidly from the interior of the Antarctic ice sheet to the coast. An analysis of surface flow convergence suggests that ice flow and geometry are intricately linked within these ice streams.
Entry into and exit from mitosis are brought about by the increase and decrease, respectively, in the activity of cyclin-dependent kinases (CDKs). Many examples are known of how the properties of particular proteins can be altered by phosphorylation, promoting processes like nuclear envelope breakdown or assembly of the mitotic spindle. The regulation of pro […]
Long non-coding RNAs (lncRNAs) have emerged as regulators of various biological processes, but to which extent lncRNAs play a role in genome integrity maintenance is not well understood. In this issue of EMBO Reports, Sharma et al  identify the DNA damage-induced lncRNA DDSR1 as an integral player of the DNA damage response (DDR). DDSR1 has both an early […]
The largest survey of gene expression ever performed in the adult human brain reveals highly stereotyped transcriptional patterning across individuals. The most stably patterned genes are enriched for neuronal annotations, disease associations, drug targets and correspond to resting state functional networks.
Previous studies have reported 'preplay' of hippocampal neural activity patterns associated with events yet to occur. Silva et al. challenge this finding on the basis of large-scale recordings before and after experiences.
Previous work has suggested that cortical recurrent circuits can self-sustain their activity without thalamic input. A study now demonstrates that this is not the case in the awake brain, which tightly locks cortical timing to thalamic activity.
Synaptic plasticity during learning is as fundamental as it is hard to study. The underlying synaptic plasticity rule has now been inferred using only the firing rate statistics of visual neurons in monkeys before and after learning.
The latest update to The IUCN Red List of Threatened Species highlights the loss of sea ice habitat due to climate warming as the single most important threat to the long-term survival of the polar bear. The update also highlights habitat degradation as a main threat to many fungus species and over-fishing as the key […]
Wildscreen is one of three organisations to be honoured with a World Tourism Award during a ceremony on November 2, 2015 at the World Travel Market, ExCel Centre, London. Tusk Trust and the TreadRight Foundation will also receive this prestigious award, with all of the organisations being recognised for their commitment to conservation, sustainable tourism d […]
