Evolutionary Biology: The Power Of Natural Selection, Nature
Excerpts: Adaptation by natural selection is the centrepiece of biology. Yet evolutionary biologists may be deluding themselves if they think they have a good handle on the typical strength of selection in nature.
The one constant in our world is change, change often wrought by our own devices. In consequence, some of the populations and species with which we cohabit have difficulty persisting. Yet organisms should be able to adapt to changing environments, as they have done for billions of years, diversifying into a bewildering array of environments.
Ethiopia Is Top Choice For Cradle Of Homo Sapiens, Nature News
Radioactive dating finds that fossil skulls are 195,000 years old.
This skull, called Omo II, is from the earliest known member of our species. ? Michael Day
Two Ethiopian fossils have been crowned as the oldest known members of our species. An estimated 195,000 years old, the pair were witness to the earliest days of Homo sapiens.
The discovery adds yet more weight to the argument that Africa, and Ethiopia in particular, was the birthplace of humans. The dating sits well with genetic analyses of modern populations, which suggest that H. sapiens first appeared in Africa around 200,000 years ago.
Why Humans Evolved Extraordinary Intelligence, Evol. & Human Behav.
Excerpts: Human cognitive abilities are extraordinary. (...) The conditions favoring the evolution of human cognitive adaptations, however, remain an enigma. Hypotheses based on traditional ecological demands, such as hunting or climatic variability, have not provided satisfying explanations. (...) What was so special about the evolutionary environments of our ancestors that caused them, and them alone, to diverge in such astonishing ways (...)? Richard Alexander proposed a comprehensive integrated explanation. He argued that as our hominin ancestors became increasing able to master the traditional "hostile forces of nature," selective pressures resulting from competition among conspecifics became increasingly important, particularly in regard to social competencies.

Perspectives for Strong Artificial Life, arXiv
Abstract: This text introduces the twin deadlocks of strong artificial life. Conceptualization of life is a deadlock both because of the existence of a continuum between the inert and the living, and because we only know one instance of life. Computationalism is a second deadlock since it remains a matter of faith. Nevertheless, artificial life realizations quickly progress and recent constructions embed an always growing set of the intuitive properties of life. This growing gap between theory and realizations should sooner or later crystallize in some kind of paradigm shift and then give clues to break the twin deadlocks.
The sizes of your social circles may be hardwired into your brain.
Circle of friends. ?A statistical analysis of social groups reveals a common structure shared by cultures around the world.
CREDIT: John Bohannon
Anthropologists have long known that people from cultures the world over--from hunter-gatherers in the Amazon to pastoralists in Africa--share similar social patterns. For example, individuals tend to organize their relationships as a hierarchy of "rings": People in the innermost ring-- known as the support clique--are the ones that come to the rescue in times of crisis. The next ring out is the sympathy group, consisting of people with "special ties" who are seen less regularly.
Discrete Hierarchical Organization Of Social Group Sizes, Phil. Tran. Biol. Sc.
Excerpts: The 'social brain hypothesis' for the evolution of large brains in primates has led to evidence for the coevolution of neocortical size and social group sizes, suggesting that there is a cognitive constraint on group size that depends, in some way, on the volume of neural material available for processing and synthesizing information on social relationships. More recently, (...) has suggested that social groups are often hierarchically structured. We combine data on human grouping patterns in a comprehensive and systematic study. Using fractal analysis, we identify, with high statistical confidence, a discrete hierarchy of group sizes (...).
Experimental Domestication Of Foxes Yields Clues To Cognitive Evolution, ScienceDaily
Excerpts: New findings, made by researchers studying the outcome of a decades-long fox-breeding experiment, suggest that some aspects of social intelligence in animals are correlated with genetically selected "tame" behavior--for example, fearlessness and non-aggression toward humans. Understanding how intelligence evolved in humans and other animals remains one of the central evolutionary questions yet to be answered by behavioral scientists. Of particular interest is how social problem solving evolves; many believe it is our own social intelligence that differentiates us from all other species. (...)
Ready, Aim, Fire!, CIO.com
Excerpts: The most cost-effective way to dramatically improve your IT organization's implementation of a new system, app or upgrade is to make sure you fire the right person. Nothing boosts morale or heightens concentration quite like the public firing of an individual who everyone knows is a persistent obstacle to discipline, collaboration, quality and ethics during an implementation. That these individuals have been able to flourish in your organization is a reproof to all your posturing about IT excellence and professionalism.
Wikipedia's Growth Comes with Concerns, NPR WE

Young And Excitable: The Function Of New Neurons In The Adult Mammalian Brain, Current Opin. Neurobiol.
Abstract: Adult neurogenesis occurs in most species and is regulated by a wide variety of environmental and pharmacological challenges. The functional integration of neurons generated in the adult was first demonstrated in songbirds more than two decades ago. In the adult mammalian brain, neurons are continuously generated in two structures, the olfactory bulb and the hippocampus. Current evidence suggests that adult-born immature neurons have distinct electrophysiological properties from old neurons, and proposed roles in a variety of functions including olfaction, learning and mood regulation.
Concrete Spatial Language: See What I Mean?, Brain & Lang.
Excerpt: Conveying complex mental scenarios is at the heart of human language. Advances in cognitive linguistics suggest this is mediated by an ability to activate cognitive systems involved in non-linguistic processing of spatial information. In this fMRI-study, we compare sentences with a concrete spatial meaning to sentences with an abstract meaning. Using this contrast, we demonstrate that sentence meaning involving motion in a concrete topographical context, whether linked to animate or inanimate subjects nouns, yield more activation in a bilateral posterior network, (...).

The Faculty of Language: What's Special About It?, Cognition
Excerpts: We examine the question of which aspects of language are uniquely human and uniquely linguistic in light of recent suggestions by Hauser, Chomsky, and Fitch that the only such aspect is syntactic recursion, the rest of language being either specific to humans but not to language (e.g. words and concepts) or not specific to humans (e.g. speech perception). We find the hypothesis problematic.(...) The hypothesis that language is a complex adaptation for communication which evolved piecemeal avoids all these problems.

Study: Sleep Helps Birds Master Singing, Discovery News
Sleep helps young birds master the art of song, according to a study that analyzed and recorded every vocalization made by young male zebra finches through cycles of wakefulness and sleep.
Picture(s): Courtesy of Cold Spring Harbor Laboratory
According to a new study, when zebra finches like these fall asleep, the brain circuits that govern their vocal learning are broken down. The bigger the breakdown, the better the birds are able to sing once they've had a chance to wake up and practice a little.
The study, (...), showed that just woken up zebra finches are dramatically worse singers than they were the day before. But surprisingly, after intense morning singing, the worst performers become the best singers of all.
Zebra finch males are active in the daytime, do not sing in darkness and develop their song during a critical window of "brain plasticity" between 30 and 90 days after hatching.
How Sleep Affects The Developmental Learning Of Bird Song, Nature
Excerpts: Sleep affects learning and development in humans and other animals, but the role of sleep in developmental learning has never been examined. Here we show the effects of night-sleep on song development in the zebra finch by recording and analysing the entire song ontogeny. During periods of rapid learning we observed a pronounced deterioration in song structure after night-sleep. The song regained structure after intense morning singing. Daily improvement in similarity to the tutored song occurred during the late phase of this morning recovery; little further improvement occurred thereafter.

A Geological History Of Reflecting Optics, Interface
Excerpts: Optical reflectors in animals are diverse and ancient. The first image-forming eye appeared around 543 million years ago.

The aim of this article is to reveal the diversity of reflecting optics in nature, introducing the first appearance of some reflector types as they appear in the fossil record (...). This article also reveals the commercial potential for these optical devices, in terms of lessons from their nano-level designs and the possible emulation of their engineering processes--molecular self-assembly.
Hearing Repaired: Gene Therapy Restores Guinea Pigs' Hearing, Science News
Now hear this. Guinea pigs like this one regrew auditory hair cells (inset) and regained their hearing after being deafened by drugs. M. Vloet; (inset) Raphael
By flipping on a gene that's normally active only during embryonic development, researchers have restored hearing to a group of profoundly deaf guinea pigs. The finding may lead to treatments for millions of people with acquired hearing loss, the team says.
Like people, guinea pigs use auditory hair cells, found deep inside the inner ear, to detect sounds. When sound waves reach them, the cells' hairlike projections sway with the vibrations and transmit electrical signals to the brain's auditory center.
Climate researchers who worry that they may have overlooked something the first time around have retested the links between the burning of fossil fuels, greenhouse warming, and the warming of the deep oceans. With greater attention this time to uncertainties, they have come up with the same answer but with even greater confidence: Humans are indeed warming the world, right down to the depths of the sea.(...)

This "nanoporous" material makes it possible to carry out reactions inside the vessels.
Surface Chemistry: Oiled Acrobatics, Nature
Excerpts: The spectacle is driven by the action of surfactant molecules, which attach uniformly to the surface of glass substrates placed in solution, thereby creating a hydrophobic coating. But when the surfactants are next to a droplet, they move from the surface into the oil phase. The resulting local perturbation of the coating makes the surface less hydrophobic, and creates a gradient in the surface tension between the front and rear of the droplet that induces motion.
(...) the droplets can be forced from random movement into regular back-and-forth motion.
Self-Running Droplet: Emergence of Regular Motion from Nonequilibrium Noise, Phys. Rev. Lett
Spontaneous motion of an oil droplet driven by nonequilibrium chemical conditions is reported. It is shown that the droplet undergoes regular rhythmic motion under appropriately designed boundary conditions, whereas it exhibits random motion in an isotropic environment. This study is a novel manifestation on the direct energy transformation of chemical energy into regular spatial motion under isothermal conditions. A simple mathematical equation including noise reproduces the essential feature of the transition from irregularity into periodic regular motion. Our results will inspire the theoretical study on the mechanism of molecular motors in living matter, working under significant influence of thermal fluctuation
The figures depict a self-running oil droplet. Drops of oil placed on glass and in a solution containing a surfactant are observed to move spontaneously, driven by a difference in surface tension between the front and back due to absorption of surfactant from the surface. Depending on the shape of the substrate, drops can execute various types of regular motion and can even climb up stairs.
Efficient Bipedal Robots Based on Passive-Dynamic Walkers, Science
Summary: In the 18 February 2004 issue of Science, Collins et al. report a new finding with implications for the development of better humanoid robots. By extending gravitationally propelled bipedal passive-dynamic walkers first developed in the 1990s, and adding simple powered actuators and controllers, the team has been able to fashion robots with improved energy efficiency compared with conventional walking robots, which commonly require large amounts of energy and complex control mechanisms. The products of the new study were also captured in action on a number of video clips, posted on Science Online.
Foundations of Swarm Intelligence: From Principles to Practice, arXiv

Excerpts: There are some computer problems so hard that computer scientists consider them out of reach. They label them "intractable" and move on. (...)
Mostly their approach is to have the computer do what a human being might do: stop, go back and start over and try something different.
