Simulating 25,000 generations of evolution, researchers discover why biological networks tend to organize

Simulating 25,000 generations of evolution, researchers discover why biological networks tend to organize | learning plant | Scoop.it

By simulating 25,000 generations of evolution within computers, Cornell University engineering and robotics researchers have discovered why biological networks tend to be organized as modules – a finding that will lead to a deeper understanding of the evolution of complexity. The new insight also will help evolve artificial intelligence, so robot brains can acquire the grace and cunning of animals. From brains to gene regulatory networks, many biological entities are organized into modules – dense clusters of interconnected parts within a complex network.

 

For decades biologists have wanted to know why humans, bacteria and other organisms evolved in a modular fashion. Like engineers, nature builds things modularly by building and combining distinct parts, but that does not explain how such modularity evolved in the first place. Renowned biologists Richard Dawkins, Günter P. Wagner, and the late Stephen Jay Gould identified the question of modularity as central to the debate over "the evolution of complexity." For years, the prevailing assumption was simply that modules evolved because entities that were modular could respond to change more quickly, and therefore had an adaptive advantage over their non-modular competitors. But that may not be enough to explain the origin of the phenomena. The team discovered that evolution produces modules not because they produce more adaptable designs, but because modular designs have fewer and shorter network connections, which are costly to build and maintain. As it turned out, it was enough to include a "cost of wiring" to make evolution favor modular architectures.

The results may help explain the near-universal presence of modularity in biological networks as diverse as neural networks – such as animal brains – and vascular networks, gene regulatory networks, protein-protein interaction networks, metabolic networks and even human-constructed networks such as the Internet. "Being able to evolve modularity will let us create more complex, sophisticated computational brains," says Clune. Says Lipson: "We've had various attempts to try to crack the modularity question in lots of different ways. This one by far is the simplest and most elegant."

Un ottimo prodotto per costruire velocemente Milestones Chart dall'aspetto estetico piacevolissimo, anzi, molto bello.

L'occhio vuole la sua parte, diceva qualcuno. E con questo prodotto si può fare un'ottima figura presentando un piano di progetto al cliente o alla propria direzione aziendale per approvazione.

Al di là dell'aspetto estetico della timeline costruita, il valore aggiunto di questo prodotto è la possibilità di creare con due click del mouse la sequenza delle milestones e delle attività incollandole da una tabella Excel o da un piano di progetto di Microsoft Project (tutte le versioni), evitando di perdere tempo a riformattare il GANTT di MS Project per presentare il piano a clienti e agli stakeholders.

L'add-on di PowerPoint in questione, ci dà anche la possibilità di indicare in modo dinamico la data odierna (Timenow) e di apportare modifiche e commenti per mostrare variazioni rispetto al piano iniziale.

Funziona con le versioni di Powerpoint 2007, 2010 e 2013.

Io l'ho appena acquistata, e nelle prossime settimane la utilizzerò per un progetto che voglio presentare ad un mio cliente a settembre.

Vi terrò aggiornati.

Bacterial Effector Proteins and their domains/motifs

Many bacterial pathogens that cause some of the world’s most devastating diseases deliver proteins (called effectors) into the cells of their host - which is a requirement to cause disease.

Over 400 predicted or proven effectors from a wide range of bacterial species have been identified that are delivered by dedicated type three secretion systems ( TTSS / T3SS). Many effector proteins are unique with little sequence similarity to any other known proteins, while others make up large effectors families. Almost all bacterial pathogens possess at least one effector that has a homologue or chimera in another bacterial species.
