The extensive exploitation of marine resources by modern fisheries (...) has wide-ranging effects on marine ecosystems. Across the world's oceans, size-selective harvesting by commercial fisheries has been a key driving force behind changes in phenotypic traits such as body size and age at maturation (1–3). These changes have altered the trophic structure of the affected ecosystems, disturbed predatorprey relationships, and modified trophic cascade dynamics (3, 4). Phenotypic changes can involve both ecological and evolutionary reactions to the effect of fishing, and there has been much debate about the relative roles of these reactions. This is important because genetic changes could result in long-term reductions in catches. Recent work has provided evidence for fisheries-induced evolutionary changes, with important implications for the sustainability of fisheries.
How Fisheries Affect Evolution Andrea Belgrano, Charles W. Fowler
The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell.
I remember reading this when first published and its a great paper. Any computational model of human cognition needs to integrate both chemical and eletrical mechanisms into a integrated whole. Great scoop and awesome paper.
This year's event is likely to be a tipping point for UK environmental monitoring and will undoubtedly help inform future UK govt and industry policies. The results of the research and different network configurations showcase will be of interest to anyone using environment sensing data be it in simulations (like us) or for direct data analysis.
Fast Company Big Data: Sweat the Little Stuff Automation World Although Big Data continues to be a hot topic, with lots of manufacturers excited about the opportunities all that data presents for even just predictive maintenance alone…we continue...
In 2004/2005 our old Creator product was used to build a concept 3D fault guided maintenance application for jet engines. The concept was sensors in the jet engine would detect state and inform the ground grew over a wireless connection maintenance need - and a 3d guided mainteance app would use the sensor data to drive the interactive electronic manual. As sensor costs plummet, big data becomes established and mobile and wifi has driven advanced networked computing platforms into everyone's pocket - that concept now becomes very prescient. For manufacturers (and interface developers) sensor driven maintenance and performance measurement platforms are going to be a key new business growth area in the coming years. Sensors and networks connect data. Software augments hardware. Insight drives opportunity. Interesting times.
My preferred job title is 'theorist', but that is often too ambiguous in casual and non-academic conversation, so I often settle for 'computer scientist'. Unfortunately, it seems that the overwhelming majority of people equate ...
Artem Kaznatcheev, a researcher in theoretical computer science - i.e. the ideas that underpin computing - has a wonderful write up of Stephanie Forrest's Stannislaw Ulam lecture at the SFI on using inspiration from Biology to address challenges in Software industry. The Ulam lecture is available in video - but its a few hours long - through seriously worth watching and covers modern developments in genetic programming and other approaches. If you need an abbrieviated write up of the key ideas underpinning the Professor Forrest's lecture - then Artem's write up is an awesomely succinct. Worth reading (and the lectures linked in his article - are worth watching!)

Interesting to see cities beginning to adopt open data policies as default. Recent open data competitions in places like New York are helping create awareness of the possibilities of using openly available data, mobile etc for innovative apps and improved city planning and governance. Looking forward to see what Louisville's decision generates.
The main aim of the Symposium is to facilitate the meeting of people working on different topics in different fields (mainly Economics, Finance and Computer Science) in order to encourage a structured multi-disciplinary approach to social sciences. Presentations and keynote sessions center around multi-agent modelling, from the viewpoint of both applications and computer-based tools. The event is also open to methodological surveys.
The event will be hosted by Social Simulation 2014, the 10th Conference of the European Social Simulation Association at the Universitat Autonoma de Barcelona, Barcelona, Spain. September 1-5th, 2014.
A few years ago, I started looking online to fill in chapters of my family history that no one had ever spoken of.
Maryn McKenna has been writing a number of articulate well informed and frankly terrifying articles in Wired on the rise of drug resistant antibiotics and their societal implications. This 4000 word essay on medium is certainly worth reading and explains her personal interest in the subject.
Social systems are among the most complex known. This poses particular problems for those who wish to understand them. The complexity often makes analytic approaches infeasible and natural language approaches inadequate for relating intricate cause and effect. However, individual- and agent-based computational approaches hold out the possibility of new and deeper understanding of such systems.
Simulating Social Complexity examines all aspects of using agent- or individual-based simulation. This approach represents systems as individual elements having each their own set of differing states and internal processes. The interactions between elements in the simulation represent interactions in the target systems. What makes these elements "social" is that they are usefully interpretable as interacting elements of an observed society. In this, the focus is on human society, but can be extended to include social animals or artificial agents where such work enhances our understanding of human society.
This handbook is intended to help in the process of maturation of this new field. It brings together, through the collaborative effort of many leading researchers, summaries of the best thinking and practice in this area and constitutes a reference point for standards against which future methodological advances are judged.
Just a month ago, the Royal Swedish Academy of Sciences announced that this year's Nobel Prize for Physics would go to two of the original six researchers who proposed the existence of the so-called "Higgs particle" in 1964.
Of al the articles on the Higgs Boson - this is a really good one that is clear and concise. Enjoyable reading.
Scientists say there was a widespread extinction of bees 66 million years ago, at the same time as the event that killed off the dinosaurs.
The demise of the dinosaurs was almost certainly the result of an asteroid or comet hitting Earth. But the extinction event was selective, affecting some groups more than others. Writing in Plos One journal, the team used fossils and DNA analysis to show that one bee group suffered a serious decline at the time of this collision.
Any study explaining why a species went extinct 65 million years ago will at first glance seem disconnected from current events. However bees are critical to agriculture and ensuring biodiversity. Understanding extinction events that impacted different species of Bees in the past help us better understand what could happen in the future as Bee's are currently being severely impacted by diesel pollution, modern farming practises (especially insecticides), changing ecosystems and new pests.

The potential for genetically modified crops and relation to climate change - which recently helped drive Monsanto to acquire The Climate Corporation is once again in the headlines. At the recent Iowa discussion, five farmers from Malawi, India, Portugal, Argentina and Kenya said they were strong believers in using biotech crops to survive and thrive in the face of a changing climate, and said that farmers needed to share ideas and help each other improve farming techniques. Trust.org does a great job in summarizing the ideas discussed at the event. Worth reading.
The Guardian How to turn open data into better government The Guardian The UK open data initiative – through which departments open up data by default for public use - is universally acknowledged as a force for democratic good.
The first year anniversary of the Open Data Institute founded by the Guardian - is generating a lot of good stories on Open Data success stories. We use open data sources in a number of current research projects and hopefully we can add to some of thos success stories over the next year. In this article the Gaurdian is highlighting open day as a force for democratic good - as the old saying goes sunlight is the best medicine.
