New Human Species Discovered, NPR TOTN
Excerpts: Researchers report this week that they have found the remains of a group of small hominids that may be a new species of human -- one that may have existed on an island near Indonesia as late as 14,000 years ago. The dwarf species of human was found in a cave on the Indonesian island of Flores. What does it mean to be a "new species?" And does the finding of these proto-humans shake up the human family tree?
Scientists Discover Species of Small Early Humans, NPR ME
Excerpts: Scientists discover fossils of a new species of early human on the Indonesian island of Flores. Like the Neanderthals, it is an alternate human line that disappeared. The creatures were surprisingly small -- no more than a meter tall, with heads the size of a grapefruit. NPR's Christopher Joyce reports.
Little Lady Of Flores Forces Rethink Of Human Evolution, Nature
Excerpts: The discovery is prompting increased scrutiny of sites on other Southeast Asian islands, both to look for more of the same species and to place it in context with Homo sapiens and Homo erectus, our closest relative. Homo erectus was found to have lived on the nearby island of Java as long as 1.6 million years ago; the team suggests that the Flores hominins may be their descendants.
(...) researchers are hoping to find DNA in the bones, which would help to clarify the relationships between species.
Evolutionary Shrinkage: Stone Age Homo Find Offers Small Surprise, Science News
H. sapiens arrived in Australia and nearby islands by at least 55,000 years ago, the scientists add, but it's not known whether or how these people interacted with their diminutive counterparts.
Little Big Find. The newly discovered Homo floresiensis skull (left) comes up short next to a Homo sapiens skull (right).
Anthropologists familiar with the Flores specimen accept it as a new Homo species. "It's amazingly tiny," (...). Further research needs to confirm that H. floresiensis' small size evolved gradually on the island, he says.
Instead, dwarfing might have occurred rapidly in a Homo species that reached Flores late in the Stone Age (...).
Palaeoanthropology: Human Evolution Writ Small, Nature
Excerpts: We are the only living species of the genus Homo. Given the startling results of a cave excavation in Southeast Asia, it seems that we coexisted with another species until much more recently than had been thought.
The fossils described elsewhere in this issue probably left no descendants, are not very old, and were found on a remote island. Despite this, they are among the most outstanding discoveries in palaeoanthropology for half a century.
Ancient, Tiny Humans Shed New Light on Evolution, NPR ATC
Excerpts: Aside from the search for evidence of the earliest modern humans in Flores, we shall also scour other remote Indonesian islands for their own array of extinct, endemic animals, which may well include other species of human. Sulawesi is an obvious target, being famous for a range of bizarre and unique creatures that imply a long period of isolation -- a necessary precursor to endemism. Perhaps the far-flung Indonesian islands have acted as a series of independent "Noah's Arks," each with their own trademark endemic dwarfs and giants.
Small Archaic Human Stuns Paleoanthropologists, Science Now
Scientists have made the startling discovery of a lost world of small archaic humans, who hunted dwarf elephants and Komodo dragons on an Indonesian island as recently as 18,000 years ago. The researchers uncovered the skull and skeleton of an adult human female with a brain the size of a grapefruit and a body the size of a Hobbit. This diminutive new species lived on the tropical island of Flores at the same time that modern humans inhabited nearby islands and were circling the globe.

Eton Or The Zoo?, BBC News
Suppose for a moment that a living tribe of these beings is discovered, how should they be treated?
A cast of the 18,000-year-old 'Hobbit's' skull
Are they merely advanced apes, or are they miniature humans?
If an explorer brought back one of their infants to study, would you put him down for Eton or the Zoo?
If he died, would he be buried in consecrated ground or a pet cemetery?
His very existence among us would make us question all over again what it is to be human.
'Hobbit' Joins Human Family Tree, BBC News
The 18,000-year-old specimen, known as Liang Bua 1 or LB1, has been assigned to a new species called Homo floresiensis. It had long arms and a skull the size of a large grapefruit.
A male Homo floresiensis may have looked something like this (Image: National Geographic)
The researchers have since found remains belonging to six other individuals from the same species.
LB1 shared its island with a golden retriever-sized rat, giant tortoises and huge lizards - including Komodo dragons - and a pony-sized dwarf elephant called Stegodon which the "hobbits" probably hunted.
Knowledge-Based Economies, Organizations And The Sociocultural Regulation Of Work, Econ. & Indus.Democ.
Excepts: A predominant economic and managerial discourse drives imperatives for a 'knowledge-based' economy, now widely espoused by economic leaders in much of the developed world. Demands for ever-modernizing efficiencies, production growth and competitive advantage encourage heightened emphasis on knowledge-rich production and innovation. (...) This article critically examines the knowledge-based economy discourse and its formulation of worker and organizational learning. It argues that alternative conceptualizations of organizational learning that recognize workers' cultural and non-material demands may stimulate resources for culturally innovative practices. In particular, the article considers ways in which learning economy discourses may be strategically utilized by trade unions, worker educators (...).
Mathematical Models For Explaining The Emergence Of Specialization In Performing Tasks, Complexity
Abstract: In an evolving community consisting of many individuals, it is often the case that the individuals tend, over time, to become more specialized in performing the tasks necessary for survival and growth of the community as a whole. The contribution in this work is a collection of linear and nonlinear mathematical models that provide insights as to when and why functional specialization emerges in general, rather than specific, settings. The results from these models, which are based on an evolutionary approach, apply to communities in which individuals allocate their time in the best interest of the community as a whole.
Buzzing the Web on a Meme Machine, NY Times
Excerpts: The World Wide Web is the perfect Petri dish for memes. Wikipedia, the free collaborative online encyclopedia, calls the Internet "the ultimate meme vector."
Meme and memetics (the study of memes, not to be confused with mimetics) were once terms batted around only by thinkers like Mr. Dawkins, the philosopher Daniel Dennett and Susan Blackmore, the author of "The Meme Machine." Now the word "meme" is part of many would-be-trendy Web addresses.
A site called memes.org says it tests "new, old and emergent memes (...).
Excerpts: Physical existence and information content are inextricably linked. (...), "It from bit."
Black holes might seem like the exception to the rule that everything computes. (...) according to Einstein's general theory of relativity, getting information out is impossible. (...) In the 1970s Stephen Hawking of the University of Cambridge showed that when quantum mechanics is taken into account, black holes do have an output: they glow like a hot coal. In Hawking's analysis, this radiation is random, however. It carries no information about what went in.
Earlier this year Dr. Hawking changed his mind, see
Hawking cracks Black Hole Paradox , ComDig 2004.29.
Excerpts: Since about 1995, microprocessors have been outrunning the other parts of computer systems (...). The latest processors churn through instructions at up to 3.6 gigahertz (GHz); some operations, such as arithmetic, run at double that rate. But the wiring on the motherboard that connects the processor to its memory chips and other pieces of the system plods along at 1 GHz or less. So the brain of the machine spends as much as 75 percent of its time idle, waiting for instructions and data that are stuck in traffic.
Organised Chaos Gets Robots Going, New Scientist
A control system based on chaos has made a simulated, multi-legged robot walk successfully. The researchers behind the feat say it may have brought us closer to understanding how people and animals learn to move.
Chaos in control
Standard robots control their leg motion either through complex computer programs or by using so-called genetic algorithms to "evolve" a successful walking strategy. Both these options are time-consuming and require a lot of computer power.
(...) simulation of a 12-legged machine in which each leg was controlled by a chaotic mathematical function.
Molecular Motors: Smooth Coupling In Salmonella, Nature
Excerpts: Bacteria such as Salmonella typhimurium move by the action of their flagella. Depending on the direction of rotation, flagella either act singly, causing uncoordinated tumbling, or clump together into a single helical propeller for straight-line swimming. The 60-nm-long hook that joins the flagellar filament to its motor in the bacterial cell wall must thus bend through as much as 90° in a millisecond or less, all the time rotating at up to 300 revolutions per second. (...) determined the atomic structure of this super-flexible universal joint, (...).
Mixing Biology and Electronics to Create Robotic Vision, U Arizona News Release
Sure they can crush humans at chess. But they can't beat us at soccer - half the time they can't even recognize the soccer ball - or defeat us in single combat and walk away from the encounter.

Single Origin for Eyes?, Science Now
Biologists have argued for decades over whether the two basic eye plans of vertebrates and invertebrates evolved independently or originated from a common ancestor. New data showing unexpected similarities between the eyes of a marine worm and those of humans

Despite incredible variation in size and shape, eyes come in just two basic models. The vertebrates' photoreceptor cells, typified by rods and cones, are quite distinctive from the invertebrates'. And although both use light-sensing pigments called opsins, these differ in their amino acid makeup.
On first glance, the virtual retinal display (VRD) developed at the University of Washington's Human Interface Technology Laboratory resembles a traditional heads-up display, a tiny monitor mounted just inches from your eyeball. In fact, (...) Mitsubishi announced an inexpensive heads-up display called SCOPO. What makes the VRD so unique is that there is no screen. The device literally paints a video image onto your eyeball with a laser beam. The picture is crisper and brighter than any competing heads-up display and doesn't guzzle power like postage-stamp LCD or LED screens.
Doctors Use Nanotechnology to Improve Health Care, NY Times
Excerpts: Evidence is accumulating that nanotechnology may enable better early warning systems for cancer and heart disease, cures for progressive diseases like cystic fibrosis, techniques for making implants like artificial hips more successful, and even artificial kidneys. But there is no reliable timeline for the home-run projects (...).
Nanotechnology involves industrial products and processes in the realm of nanometers, or billionths of a meter. That is also the scale on which all living cells - and the things that nourish or kill them - operate.

Ultrasound Scans Accused Of Disrupting Brain Development, Nature
Excerpts: The effect of ultrasound scans on brain development is to be investigated in a study on monkeys starting next month in the United States. The work has been prompted by unpublished research showing that ultrasound can disrupt the normal movement of cells through the brains of unborn mice.
The $3-million study, which is funded by the US National Institute of Neurological Disorders and Stroke in Bethesda, Maryland, will examine the effect of scans on the unborn offspring of around 50 rhesus macaque monkeys.
The drug fluoxetine--commonly known as Prozac--has been used as an antidepressant for almost 20 years, but a new study suggests that it may actually raise anxiety levels in newborn mice.

Fluoxetine is the oldest of the selective serotonin reuptake inhibitors (SSRIs) and the only one approved for pediatric use.
In comparison to the saline-treated pups, the fluoxetine-treated mice explored less while in a maze. (...) All these behaviors are regarded as signs of anxiety and depression in animals.
Excerpt: Growing up in a family that lacks a biological father is correlated with a number of poor outcomes for youths. (...) examine the extent to which differences in income or parental involvement can explain the effects of family structure on youth outcomes. We find that measurement error in income from single-parent homes has a large effect on the results because of the variability in income earned over a youth's teen years. Overall, we find that lower income explains most of the disadvantages of youths in single-parent homes, but neither gaps in income nor in parental involvement explain the disadvantages of families with stepfathers.

Researchers Develop Neural Prosthesis Allowing A Monkey To Feed Self Using Only Its Brain, ScienceDaily
Excerpts: Researchers (...) demonstrated that a monkey can feed itself with a robotic arm simply by using signals from its brain, an advance that could enhance prosthetics for people (...). The robotic arm, or neural prosthesis, is about the size of a child's arm and moves much like a natural arm, with a fully mobile shoulder and elbow and a simple gripper that allows the monkey to grasp and hold food while its own arms are restrained. The arm is wired into the monkey's brain and intercepts signals through electrodes attached to tiny probes that tap into neuronal pathways in the motor cortex, (...).
Advent of the Robotic Monkeys, Wired
If a monkey is hungry but has his arms pinned, there's not much he can do about it. Unless that monkey can control a nearby robotic arm with his brain.
This time lapse photo shows a lab monkey at the University of Pittsburgh using a robotic arm to feed itself. Photo: Courtesy of UPMC News Bureau
And that's exactly what the monkey (...) can do, feeding himself using a prosthetic arm controlled solely by his thoughts.(...)
(...) as the monkey thinks about bringing the food to his mouth, electrodes in the monkey's brain intercept the neuronal firings that are taking place in the motor cortex, a region of the brain responsible for voluntary movement.
Music and the Brain
Excerpts: (...) when musicians listen to a piano playing, about 25 percent more of their left-hemisphere auditory regions respond than do so in nonmusicians. (...) expansion of response area is greater the younger the age at which lessons began. Studies of children suggest that early musical experience may facilitate development. (...) recorded brain responses to piano, violin and pure tones in four- and five-year-old children. Youngsters who had received greater exposure to music in their homes showed enhanced brain auditory activity, comparable to that of unexposed kids about three years older.
Can't Place A Name To The Face You Just Saw?, ScienceDaily
Excerpts: Ever catch a glimpse of someone but can't quite fit a name to go with the face? While it's something that happens to everyone, for older people especially, difficulty in retrieving names is a common frustration. Scientists (...) are trying to determine what goes on inside the brain when it sees a face. How, for instance, does the brain recognize faces and retrieve the names to go with them? Also, how does the brain determine whether the information that it has retrieved is accurate? (...)
An Explanatory Model for Food-web Structure and Evolution, arXiv
Abstract: Food webs are networks describing who is eating whom in an ecological community. By now it is clear that many aspects of food-web structure are reproducible across diverse habitats, yet little is known about the driving force behind this structure. Evolutionary and population dynamical mechanisms have been considered. We propose a model for the evolutionary dynamics of food-web topology and show that it accurately reproduces observed food-web characteristic in the steady state. It is based on the observation that most consumers are larger than their resource species and the hypothesis that speciation and extinction rates decrease with increasing body mass. Results give strong support to the evolutionary hypothesis.
Predation Risk Is An Ecological Constraint For Helper Dispersal In A Cooperatively Breeding Cichlid, Alphagalileo & Proc. B
Abstract: Sexually mature subordinates of the Lake Tanganyika cichlid Neolamprologus pulcher help raise the young of dominant breeders, and therefore they are called 'helpers'. We show in a controlled field experiment that helpers exposed to predators stay at home rather than disperse and breed independently. Predators decreased the survival of helpers, but less so when helpers were living in large groups. This experiment supports the long-held view that predation risk selects for group-living and against independent breeding of helpers.
The Evolutionary Origin of Cooperators and Defectors, Science
Abstract: Coexistence of cooperators and defectors is common in nature, yet the evolutionary origin of such social diversification is unclear. Many models have been studied on the basis of the assumption that benefits of cooperative acts only accrue to others. Here, we analyze the continuous snowdrift game, in which cooperative investments are costly but yield benefits to others as well as to the cooperator. Adaptive dynamics of investment levels often result in evolutionary diversification from initially uniform populations to a stable state in which cooperators making large investments coexist with defectors who invest very little. Thus, when individuals benefit from their own actions, large asymmetries in cooperative investments can evolve.
Symmetry Breaking and the Evolution of Development, Science
Excerpts: Because of its simplicity, the binary-switch nature of left-right asymmetry permits meaningful comparisons among many different organisms. Phylogenetic analyses of asymmetry variation, inheritance, and molecular mechanisms reveal unexpected insights into how development evolves. First, directional asymmetry, an evolutionary novelty, arose from nonheritable origins almost as often as from mutations, implying that genetic assimilation ("phenotype precedes genotype") is a common mode of evolution.
Second, the molecular pathway directing hearts leftward-the nodal cascade-varies considerably among vertebrates (homology of form does not require homology of development) (...).
That Familiar Nest Odor, Science Now
Excerpts: But new research shows that a species of seabird prefers the scent of its mate to those of other individuals in the colony. The odors may help the birds locate their burrows and, perhaps, even choose a partner.
(...) The pairs build shallow burrows and then split the duty of incubating the eggs, spending the rest of their time looking for food. Because prions can locate their own burrows among those of hundreds of neighbors in the middle of the night, researchers (...), began to suspect that they were using odor cues.
'Smelly' Mates Guide Seabirds, BBC News
eabirds called prions, which mate for life, find their nests by sniffing out their smelly partners, scientists say.
Prions are strictly monogamous, although they rarely get to spend any time with their partners
The birds make their nests in deep burrows, which are very dark, so they cannot rely on any other sense to find them, Science magazine reports.
The birds also actively avoid their own smell, which could be a way of making sure they do not breed with their kin.
Partner-Specific Odor Recognition in an Antarctic Seabird, Science
Abstract: Among birds, the Procellariiform seabirds (petrels, albatrosses, and shearwaters) are prime candidates for using chemical cues for individual recognition. These birds have an excellent olfactory sense, and a variety of species nest in burrows that they can recognize by smell. However, the nature of the olfactory signature--the scent that makes one burrow smell more like home than another--has not been established for any species. Here, we explore the use of intraspecific chemical cues in burrow recognition and present evidence for partner-specific odor recognition in a bird.
Evolutionary Biology: Mortality And Lifespan, Nature
Excerpts: How does natural selection affect lifespan? The question has exercised biologists for some years. The latest twist comes from ingenious experiments on tropical fish from different ecological backgrounds.
(...) investigated one of the main factors that influence the evolution of an organism's lifespan. That factor is the risk of dying that a population faces as a result of environmental conditions (such as, in this case, predation). The study subjects are guppies, (...), that a higher environmental risk of mortality can select for inherently longer-lived organisms.
Hunted Guppies Live Longer, Science Now
According to classical evolutionary theory, animals faced with low chances of survival should do best by following the "live fast and die young" strategy. But new studies of guppies suggest that we need more sophisticated theories to describe how evolution shapes life span.
Life in the slow lane. Contrary to evolutionary predictions, guppies forced to share their pool with predators age more slowly.
CREDIT: DAVID REZNICK/UNIVERSITY OF CALIFORNIA, RIVERSIDE
When predators abound, it doesn't make much sense to invest energy in long-term survival. Instead, animals should mature quickly and reproduce prolifically. Studies in the wild and the lab have mostly supported this idea, but guppies living in waterfall-strewn streams in Trinidad seem to buck the theory.
Earthquake Prediction: A Seismic Shift In Thinking, Nature
Excerpts: (...) the USGS is moving to re-establish the National Earthquake Prediction Evaluation Council, a committee charged with advising the director of the USGS on the merits of particular predictions. (...) Regional Earthquake Likelihood Models - hopes to begin contrasting various forecast models for California by January 2005.(...)
Even more discouraging, an assembly of 1,224 Global Positioning System (GPS) stations and about 1,000 seismometers spread around the Japanese archipelago failed to spot any seismic hints of the magnitude 8.0 Tokachi-Oki earthquake that shook northern Japan last September.
An Effective Approach to Climate Change, Science
Excerpts: The Administration's more substantive R&D initiatives, such as Hydrogen Fuels and FutureGen (clean coal) are relatively modest investments in technologies that are decades away from deployment. We need a far more vigorous effort to promote energy efficient technologies; to prepare for the hydrogen economy; to develop affordable carbon capture and sequestration technologies; and to spur the growth of renewable energy, biofuels, and coal-bed methane capture.
Equally important, we need to encourage public and private investment in a wide-ranging portfolio of low-carbon technologies.
Deluge Of Typhoons May Aid Forecast Models, Nature
Excerpts: Kurihara and others are hoping that data from this year's storms can be compared with results from models of typhoons and the wider global climate system, and will lead to improvements in the models. Akira Hasegawa, also of the Frontier centre, says that their model on the Earth Simulator - Japan's most powerful supercomputer - suggests that increased levels of carbon dioxide in the atmosphere will lead to lower or constant typhoon frequencies, with more rain. "If global warming continues, we will get typhoons with increasingly torrential rains, (...).
Tidal Wave Threat 'Over-hyped', BBC News

How Strategists Design the Perfect Candidate, Science
Excerpts: This year the two major parties in the U.S. presidential race have spent nearly $500 million (...). Yet for all their talk of polls, strategies, and spin control, many political scientists acknowledge that the "science" in their discipline often resembles a black art. What really sways the electorate? A candidate's record? (...) "The surprising reality," (...), "is that we still understand relatively little about how presidential campaigns affect the vote."
Political analysts are on the case, though, tackling age-old problems with brute-force number crunching and even mathematics imported from theoretical physics.
Gambling With Our Votes?, Science
Excerpts: On the eve of the U.S. elections, many experts warn that it will take a major overhaul to make reliable, secure electronic ballots more than a virtual reality
(...) When Americans head to the polls next week, tens of millions of them will vote in much the same way: by making ticks or writing names on slips of paper. As many as 30% of ballots, however, will be cast electronically, on touch-screen or push-button computerized tabulators built by vendors such as Diebold, Sequoia, ES&S, and a handful of others.

Bin Laden's October Surprise, BBC News
Excerpts: "We did not find it difficult to deal with Bush and his administration because it is similar to regimes in our countries, half of which are governed by the military and the other half of which are governed by the sons of kings and presidents," he said. "In both categories, you find many who are characterised by hubris, arrogance, greed, and unlawful acquisition of money."
