Hawking Cracks Black Hole Paradox, NewScientist 
Excerpts: After nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong. It seems that black holes may after all allow information within them to escape. (...)
It was Hawking's own work that created the paradox. In 1976, he calculated that once a black hole forms, it starts losing mass by radiating energy. This "Hawking radiation" contains no information about the matter inside the black hole and once the black hole evaporates, all information is lost.
Hawking Revises Theory On Escaping Black Holes, CBC.CA News
Excerpts: He theorized that once a black hole forms, it never releases information about the matter it has gobbled up.
This "Hawking radiation" created a paradox, because the laws of quantum physics say such information can never be completely destroyed.
Hawking now says some of the information can be determined by what a black hole emits.
"A black hole only appears to form but later opens up and releases information about what fell inside," (...) "So we can be sure of the past and predict the future."
The Scientific Impact Of Nations, Nature
Excerpts: What different countries get for their research spending.
The ability to judge a nation's scientific standing is vital for the governments, businesses and trusts that must decide scientific priorities and funding. In this paper I analyse the output and outcomes from research investment over the past decade, to measure the quality of research on national scales and to set it in an international context. There are many ways to evaluate the quality of scientific research, but few have proved satisfactory.
Science Education: Doing It For The Kid, Nature
Excerpts: A few brave postdocs are mixing science with school teaching.
In collaboration with the pharmaceutical company GlaxoSmithKline, it offers three-year contracts to postdoctoral researchers, combined with a teacher-training course. Richard Sykes, former chairman of GlaxoSmithKline and current rector of Imperial College, is the driving force behind the scheme, which began in September 2002. Since joining Imperial in 2001, he has become concerned by the shrinking pool of science applicants.
Sykes believes that INSPIRE can shape the next generation of scientists while they are still in the classroom.
Goal Setting And Cheating: Why They Often Go Together In The Workplace, Knowledge@Wharton
Excerpts: From childhood on, individuals are told that setting goals for themselves will make them more diligent, more focused and generally more successful (...).
But goal-setting also has a dark side to it (...). In addition to motivating constructive behavior, goal setting - especially when it involves rewards - can motivate unethical behavior when people fall short of the goals they set or that are set for them. The relationship between goal setting and unethical behavior is particularly strong when people fall just short of reaching the goal.
Unbinding Biological Autonomy: Francisco Varela's Contributions to Artificial Life, Artificial Life
Excerpts: To say that artificial life is a young discipline in name only is to exaggerate, but it would be mistaken to think that its goals are new. The marriage of synthetic scientific aims with computational techniques makes artificial life a product of the last fifteen years, but its motivations have much deeper roots in cybernetics, theoretical biology, and the age-old drive to comprehend the mysteries of life and mind. (...) What is an organism? What is cognition? Where do purposes come from?

Complexity In The Oil Market, Interciencia
Abstract: Commodity prices are very difficult to predict. (....) ... the pattern of the time series for the prices and volumes of Brent crude oil sold in the London International Exchange, was analyzed using non linear analysis techniques developed for complex systems. (...) the variations in the price index and volume of oil exchanged are not random and differ among them. The variations of prices are asymmetric regarding time, showing higher odds for large decreases compared to increases in price. The price index values show more or less stable short periods in time, suggesting strong historic constrains for prices but not for volumes.
Complexity Results For Flow-Shop And Open-Shop Scheduling Problems With Transportation Delays, Annals Op. Res.
Excerpts: We consider shop problems with transportation delays where not only the jobs on the machines have to be scheduled, but also transportation of the jobs between the machines has to be taken into account. Jobs consisting of a given number of operations have to be processed on machines (...). Transportation delays occur if a job changes from one machine to another. The objective is to find a feasible schedule which minimizes some objective function. A survey of known complexity results for flow-shop and open-shop environments is given and some new complexity results are derived.
Scheduling with Fuzzy Methods, arXiv
Abstract: Nowadays, manufacturing industries -- driven by fierce competition and rising customer requirements -- are forced to produce a broader range of individual products of rising quality at the same (or preferably lower) cost. Meeting these demands implies an even more complex production process and thus also an appropriately increasing request to its scheduling. Aggravatingly, vagueness of scheduling parameters -- such as times and conditions -- are often inherent in the production process. In addition, the search for an optimal schedule normally leads to very difficult problems (NP-hard problems in the complexity theoretical sense), which cannot be solved effciently. With the intent to minimize these problems, the introduced heuristic method combines standard scheduling methods with fuzzy methods to get a nearly optimal schedule within an appropriate time considering vagueness adequately.
Entrepreneurship, Chaos and the Tourism Area Lifecycle, Annals of Tourism Research
Abstract: Entrepreneurship is a critical factor in tourism development, both globally and regionally. However, inadequate methodological tools have impeded its study. Chaos and complexity theory provides a valuable perspective to destination development research especially when combined with the Tourism Area Lifecycle Model. The synthesis creates a framework that takes into account different types of entrepreneurial activity while highlighting elements of turbulence, change, and, unpredictability. This paper provides an example of the development of two Australian destinations, illustrating how entrepreneurs took advantage of chaos and turbulence, and applied their creativity in a manner that gave one destination a competitive advantage over the other.
On The Computational Complexity Of Consumer Decision Rules, Computational Economics
Abstract: A consumer entering a new bookstore can face more than 250,000 alternatives. The efficiency of compensatory and noncompensatory decision rules for finding a preferred item depends on the efficiency of their associated information operators. At best, item-by-item information operators lead to linear computational complexity; set information operators, on the other hand, can lead to constant complexity. We perform an experiment demonstrating that subjects are approximately rational in selecting between sublinear and linear rules. Many markets are organized by attributes that enable consumers to employ a set-selection-by-aspect rule using set information operations. In cyberspace decision rules are encoded as decision aids.

A Survey Of Publication Bias Within Evolutionary Ecology, Alphagalileo & Biol. Lett.
Abstract: Publication bias can be a serious research problem if results of published studies consistently differ from any results that are left unpublished. Cassey and colleagues used information gathered in a recent meta-analysis of facultative sex ratio adjustment in birds (Proc. R. Soc., B 271: 1277-1282) to assess the magnitude of publication bias that can manifest when a difference exists between results that are published with and without statistical information of the strength or direction of research findings. The authors show that publication bias is a persistent problem in evolutionary ecology literature and suggest authors and editors should respond to this.
Simulation and Experiment of Extinction or Adaptation, arXiv
Abstract: Can unicellular organisms survive a drastic temperature change, and adapt to it after many generations? In simulations of the Penna model of biological ageing, both extinction and adaptation were found for asexual and sexual reproduction as well as for parasex. These model investigations are the basis for the design of evolution experiments with heterotrophic flagellates.
Migrating Birds Offer Insight Into Sleep, ScienceDaily
Excerpts: A newly published study (...) points the way to solving (...) mysteries: how birds that migrate thousands of miles every year accomplish the feat on very little sleep and what that ability means for humans who are seriously sleep-deprived or face significant sleep problems. The study (...) found that a group of sparrows studied in the laboratory dramatically reduced how long they slept during the time they would ordinarily be migrating. But (...) perform normally despite their sleep deprivation. During times when the birds were not migrating, however, sleep deprivation appeared to impair their performance - similar to what happens to sleep-deprived humans. (...)
Hormone Boost That Helps Female Fish Tune In To Males' Love Songs, Cornell News Release
Excerpts: Without enough estrogen-like hormone in their systems, female plainfin midshipman fish turn a deaf ear to the alluring love songs of the males. And, according to Cornell University biologists, a similar steroid-sensitive response could underlie changes in the hearing sensitivity of humans. The biologists experimentally boosted levels of the steroid hormone in non-reproductive females of the fish species Porichthys notatus, temporarily altering their inner-ear auditory mechanism so they could hear the males' hum-like advertisement call that says, essentially: "I have prepared a nest under a rock in shallow water, so deposit your eggs for me to fertilize, and together we'll make beautiful small fry."
Neural Constraints On The Complexity Of Avian Song, Brain, Behav. & Evol.
Excerpts: Why do birds sing? In many species, because the song attracts or retains a mate. Why do females pay attention? This paper reviews evidence that females may do so because male song can be an honest indicator of attributes of a male's brain that could contribute to his fitness (...). Male songbirds learn and produce their songs using a set of brain regions collectively known as the song system. The learning has distinct auditory and motor components, and current data suggest that the neural changes that encode these forms of learning primarily occur in different subdivisions of the song system.

Excerpts: Robotic devices are helping shed light on human motor control in health and injury. By using robots to apply novel force fields to the arm, investigators are gaining insight into how the nervous system models its external dynamic environment. (...) Robots can haptically assess sensorimotor performance, administer training, quantify amount of training, and improve motor recovery. In addition to providing insight into motor control, robotic paradigms may eventually enhance motor learning and rehabilitation beyond the levels possible with conventional training techniques.
Honey Bee Nest Thermoregulation: Diversity Promotes Stability, Science
Excerpts: A honey bee colony is characterized by high genetic diversity among its workers, generated by high levels of multiple mating by its queen. (...). Here we show that brood nest temperatures in genetically diverse colonies (i.e., those sired by several males) tend to be more stable than in genetically uniform ones (i.e., those sired by one male). One reason this increased stability arises is because genetically determined diversity in workers' temperature response thresholds modulates the hive-ventilating behavior of individual workers, preventing excessive colony-level responses to temperature fluctuations.
Population Ecology: A Three-Player Solution, Nature
Excerpts: Mathematical models based on experimental data can provide insights about the extent to which these different factors are at play. Beyond this, however, there are some strange circumstances in need of an explanation. For example, of the approximately 80 different forest species of moths and butterflies (Lepidoptera) that exhibit large outbreaks, at least 18 are to some degree cyclical. That is, outbreaks recur in a regular fashion, and although not perfectly cyclical they have an average periodicity of 8-14 years.
The Combined Effects Of Pathogens And Predators On Insect Outbreaks, Nature
Excerpts: The economic damage caused by episodic outbreaks of forest-defoliating insects has spurred much research, yet why such outbreaks occur remains unclear. (...)Here we show that insect outbreaks can be explained by a model that includes both a generalist predator and a specialist pathogen. In this host-pathogen-predator model, stochasticity causes defoliator densities to fluctuate erratically between an equilibrium maintained by the predator, and cycles driven by the pathogen. Outbreaks in this model occur at long but irregular intervals, matching the data. (...) consider interactions among multiple species.
Embryology: Plane Talk, Nature
Excerpts: In mammals, is the three-dimensional body plan ingrained in the egg at or before fertilization? The answer is 'maybe, but then again maybe not'. Less invasive techniques might help to resolve matters.
Hans Spemann neatly summed up the importance of embryonic axes for correct animal development: "We are standing and walking with parts of our body which could have been used for thinking had they developed in another part of the embryo." But how and when are the embryonic axes established?

Plant Biology: Good Neighbours, Nature
Excerpts: Plants depend on structures called stomata to regulate gas exchange with the air, and their positioning is crucial. A key factor controlling stomatal development and arrangement has now been found.
We all need good neighbours, but plant guard cells need them more than most. Destined to remain where they are produced, these cells cannot function efficiently without help from adjacent cells. (...) a recently identified enzyme in the flowering plant Arabidopsis thaliana, christened YODA (YDA), is crucial to the formation and arrangement of stomata.
Developmental Biology: Heading Away From The Rump, Nature
Excerpts: How does our rump come to be separated from our head, instead of being right behind our ears? Studies of the elongation of the developing embryo reveal some remarkable underlying mechanisms.
The early vertebrate embryo consists of a relatively featureless ball of thousands of cells, which reshapes itself to form a head at one end, a rump or tail at the other, and an elongated trunk in between. (...). The cells intercalate (...) producing mobile protrusions called lamellipodia on their right and left surfaces that pull the cells between one another.
Fractal Patterns Of Early Life Revealed, NewScientist
Excerpts:
This fractal-like "colony" of tubes is about 1.5 cm across and 2.5 cm long (Image: Science)
|
Newly uncovered fossils reveal in extraordinary clarity the strangeness of the Earth's earliest complex life.
The finds show that the organisms were assembled in fractal patterns from frond-like building blocks. They were unable to move and had no reproductive organs, perhaps reproducing by dropping off new fronds.
The creatures, which were neither animals or plants, are called "rangeomorphs". They first appeared on the ocean floor 575 million years ago, after the last global glaciation, and were among the first of the soft-bodied creatures in the Ediacaran period.
Blood Traffic Control, Nature
Excerpts: Red blood cell vasodilation: nitric oxide and haemoglobin help to match blood flow to metabolic demand.
Textbook ideas regarding the delivery of oxygen to the body's tissues tend to focus on the cooperativity in the binding and release of oxygen from the transport protein haemoglobin. (...) - the main determinant of oxygen delivery is blood flow.
In the microcirculation, blood flow is regulated by physiological oxygen gradients. The progressive decrease in the oxygen content of blood (...) as the diameter of the arteriolar blood vessels decreases is coupled to graded vasodilation.

Robots (Probably) Won't Turn Against Humanity, Experts Say in Their Defense, The New York Sun
Excerpts: "ASIMO is designed by people. It's designed to help people," (...). "It's designed to do good."
The robots in the film are also designed to do good, (...) robots can't possibly harm humans because of the three laws of robotics encoded into their computerized brains. The first law is not to harm people; the second is to obey people as long as doing so doesn't conflict with the first law, and the third is that the robot should protect itself as long as it doesn't conflict with the first two laws.
Polite Computers Win Users' Hearts And Minds, NewScientist
Excerpts: Computer glitches would be a lot less annoying if the machines were programmed to acknowledge errors gracefully when something goes wrong, instead of merely flashing up a brusque "you goofed" message.
The trick, according to a researcher who has analysed users' responses to their computers, is to make operating systems and software more "civilised" by saying sorry more often. That way people won't feel they are stupid or at fault, so they become less apprehensive about using computers, and perhaps more productive and creative.
Devastated by AIDS, Africa Sees Life Expectancy Plunge, NY Times
Excerpts: Africa is getting poorer and hungrier as life expectancy continues its steep decline in the countries hardest hit by the AIDS pandemic, (...). It said infants born now in seven nations with high rates of H.I.V. infection could expect to live less than 40 years.
The report, by the United Nations Development Program, also said the sub-Saharan African region as a whole was getting poorer, with the prospect that rising numbers of Africans will subsist on less than $1 a day in the years to come.
An Emerging Catastrophe, NY Times
Excerpts: The staggering level of joblessness among black men mocks the very idea of stable communities. (...)
A new study of black male employment trends has come up with the following extremely depressing finding: "By 2002, one of every four black men in the U.S. was idle all year long. This idleness rate was twice as high as that of white and Hispanic males." (...)
It is believed that up to 10 percent of the black male population under age 40 is incarcerated.
Reconsidering E-Voting, NY Times
Excerpts: (...) a nefarious programmer could escape detection by exploiting the write-in candidate feature of every touchscreen voting machine. (You tap the Write-In button, and then type on-screen keys to enter your write-in's name.) Dill points out that the trigger for switching the software into election-stealing mode could be writing in "an implausible candidate name. How about a last minute campaign to write in a joke candidate? The joke candidate wouldn't be in the tests, and voters wouldn't even know they were triggering the code."

When Elections Threaten Democracy, NY Times
Excerpts: In the rush to hold elections in Afghanistan, basic democratic principles are being wholly ignored or bypassed. (...)
Moreover, the territorial boundaries for the district-level elections have yet to be ascertained. Having open hearings in order to avoid gerrymandering is a mere afterthought at this point. And the few months postponement in the elections won't be much help - measuring voting boundaries during winter is virtually impossible, as most of the country becomes inaccessible. Thus, the delay only increases already heightened suspicions against unchecked presidential powers.

In particular, the agencies' willingness to trust human sources whose credibility should have been much more suspect was a serious institutional error. And, on the status of Iraq's nuclear program, the agencies clearly stopped looking at the evidence and bought into Washington groupthink.

Dress Code May Hinder Their Work, Air Marshals Say, NY Times
Excerpts: The dress code imposed by the Department of Homeland Security makes federal air marshals uneasy that it is too easy for terrorists to spot them.
(...) a dress code was put in place in April 2002 after the airline industry complained that air marshals' attire was too casual. (...)
"In order to gain respect in a situation, you must be attired to gain respect," (...). He said if air marshals were allowed to be too casual in their dress, "they probably would not gain the respect of passengers (...)."
Al Qaida Evolves Into Regional Networks, Middle East Newsline
Excerpts: Al Qaida has adjusted to the U.S.-led war by transforming into regional autonomous networks.
A report said Al Qaida has become a different organization over the last 32 months in wake of the suicide strikes on New York and Washington. Without its haven in Afghanistan, Al Qaida has decentralized with an emerging presence in Iraq.
"Al Qaida has adjusted to the relentless assault on its leadership structure by devolving into a set of regional networks -- each with its own political agenda and operational schedule (...)
