One Hundred Years of Uncertainty, NY Times
Excerpts: Although we have yet to fully lay bare quantum mechanics' grand lesson for the underlying nature of the universe, I like to think even Einstein would be impressed that in the 50 years since his death our facility with quantum mechanics has matured from a mathematical understanding of the subatomic realm to precision control. Today's technological wizardry (computers, M.R.I.'s, smart bombs) exists only because research in applied quantum physics has resulted in techniques for manipulating the motion of electrons - probabilities and all - through mazes of ultramicroscopic circuitry
A Lucrative Brand of Tutoring Grows Unchecked, NY Times
Excerpts: Propelled by the No Child Left Behind law, the federally financed tutoring industry has doubled in size in each of the last two years, with the potential to become a $2 billion-a-year enterprise, market analysts say. (...)
This new brand of tutoring is offered to parents by private companies and other groups at no charge if their children attend a failing school. But it is virtually without regulation or oversight, causing concern among school districts, elected officials and some industry executives.
Fixing 'No Child Left Behind', NY Times
Excerpts: The United States has historically viewed public education as a local issue, so the federal government has looked the other way when the states have damaged the national interest by failing to educate large swaths of the population. That approach has left us with one of the weakest educational systems in the developed world.
The No Child Left Behind Act, signed into law three years ago, marked a recognition by Congress that things had to change. (...)
Do 15-Month-Old Infants Understand False Beliefs?, Science
Excerpts: For more than two decades, researchers have argued that young children do not understand mental states such as beliefs. Part of the evidence for this claim comes from preschoolers' failure at verbal tasks that require the understanding that others may hold false beliefs. Here, we used a novel nonverbal task to examine 15-month-old infants' ability to predict an actor's behavior on the basis of her true or false belief about a toy's hiding place. Results were positive, supporting the view that, from a young age, children appeal to mental states-goals, perceptions, and beliefs-to explain the behavior of others.
Infants' Insight into the Mind: How Deep?, Science
Excerpts: Although primates and other animals seem to have some understanding of mind (that is, the behavior of others), the concept of belief seems to be a specifically human ability. Comprehending false belief is the clearest sign of understanding a critical aspect of the mind: its subjectivity and its susceptibility to manipulation by information. It is thought that children develop an understanding of false belief around 4 years of age.
Keeping Fear in Check, Science Now
The findings suggest that vasopressin and oxytocin have contrasting influences on behavior because they have opposite effects on the output neurons of the central amygdala, (...). The researchers speculate that natural variations in the balance of vasopressin and oxytocin receptors in the central amygdala could explain why some individuals are typically nervous, while others are seemingly immune to anxiety.

The reality is much more complicated and can only be appreciated with a deeper understanding of behavioral biology," (...).
Vasopressin And Oxytocin Excite Distinct Neuronal Populations In The Central Amygdala, Science
Excerpts: Vasopressin and oxytocin strongly modulate autonomic fear responses, through mechanisms that are still unclear. We describe how these neuropeptides excite distinct neuronal populations in the central amygdala, which provides the major output of the amygdaloid complex to the autonomic nervous system. We identified these two neuronal populations as part of an inhibitory network, through which vasopressin and oxytocin modulate the integration of excitatory information from the basolateral amygdala and cerebral cortex in opposite manners. Through this network, the expression and endogenous activation of vasopressin and oxytocin receptors may regulate the autonomic expression of fear.
Building a Spinal Cord Network, Science Now
Research with animals, for example, has shown that severed spinal cord axons can in fact regenerate, with a little help. But Johnson and the panel emphasize that regeneration will only be one part of the multifaceted approach needed to treat spinal cord injuries. Not only do axons need to regenerate, he says, they must repair their damaged myelin insulation and reconnect with other neurons. And not just any neurons--forming the wrong connections can lead to neuropathic pain or other complications

Marburg's Behaviour Bewilders Scientists, Nature News
The current outbreak of the deadly Marburg virus in Angola is raising difficult questions about this enigmatic pathogen and its origins.
As of 5 April, Angolan health officials had reported 181 cases of Marburg haemorrhagic fever, of which 156 have been fatal. The outbreak of the rare but lethal virus, which causes fever and circulatory collapse, is the worst ever recorded.
The Marburg virus has infected mostly children in this outbreak. ? SPL
Emory Scientist Finds Different Paths Lead To Similar Cognitive Abilities, EurekAlert
Excerpts: Despite the divergent evolutionary paths of dolphins and primates -- and their vastly different brains -- both have developed similar high-level cognitive abilities, (...).
While modern humans have brains that are seven times bigger than would be expected for our body size, giving us an encephalization level of seven, some modern dolphins and whales have an encephalization level close to five -- not a huge difference, says Marino. For example, Homo sapiens' closest relatives, the great apes, have encephalization levels of only two to two-and-a-half.

Sony patent takes first step towards real-life Matrix, New Scientist
IMAGINE movies and computer games in which you get to smell, taste and perhaps even feel things. That's the tantalising prospect raised by a patent on a device for transmitting sensory data directly into the human brain - granted to none other than the entertainment giant Sony.
The technique suggested in the patent is entirely non-invasive. It describes a device that fires pulses of ultrasound at the head to modify firing patterns in targeted parts of the brain, creating "sensory experiences" ranging from moving images to tastes and sounds. This could give blind or deaf people the chance to see or hear, the patent claims.[...]
When hit with a burst from an ultraviolet laser, the ATP broke free, activating the rat ion channels and causing the fly's neurons to fire, (...).

(...), the laser caused sedentary flies to become hyperactive. If the ion channel were expressed in the giant fiber neurons, which control reflexes for escape, the flies could be made to leap about, buzz their wings, and fly. The method could be used to study a plethora of other behaviors, including courtship, mating, and feeding, the researchers say.
Radar Reveals Purpose In Butterfly Flights, Nature News
Tiny radar devices have revealed patterns in the meandering flights of butterflies: the looping dives are thought to help them to search for food or a home. What's more, the radar technology could help conservationists to find safe havens for the insects amid fragmented agricultural landscapes.
Researchers attached radio transponders, each weighing just 12 milligrams, to butterflies and used them to track around 30 of the insects. "You have to carefully remove the hairs from their back first," explains Lizzie Cant of Rothamsted Research in Hertfordshire, UK. "I give them a wax with Sellotape."
The butterflies carried tiny radio transponders on their backs. ? bbsrc
Tracking Butterfly Flight Paths Across The Landscape With Harmonic Radar, Proc. Biol. Sc.
Excerpts: For the first time, the flight paths of five butterfly species were successfully tracked using harmonic radar within an agricultural landscape. Until now, butterfly mobility has been predominantly studied using visual observations and mark-recapture experiments. Attachment of a light-weight radar transponder to the butterfly's thorax did not significantly affect behaviour or mobility. Tracks were analysed for straightness, duration, displacement, ground speed, foraging and the influence of linear landscape features on flight direction. Two main styles of track were identified: (A) fast linear flight and (B) slower nonlinear flights involving a period of foraging and/or looped sections of flight. (...)
Non-Acoustic Sensors Detect Speech Without Sound, New Scientist
Excerpts: DARPA is also pursuing an approach first developed at NASA's Ames lab, which involves placing electrodes called electromyographic sensors on the neck, to detect changes in impedance during speech. A neural network processes the data and identifies the pattern of words. The sensor can even detect subvocal or silent speech. The speech pattern is sent to a computerised voice generator that recreates the speaker's words.
A decade after the idea became the topic of his doctoral dissertation, a researcher at the California Institute of Technology has showed that it is possible to coax short strands of artificial DNA to spontaneously assemble into a Sierpinski triangle.
A Sierpinski triangle is a type of crystal, or structure that regularly repeats. The Sierpinski triangle is fractal -- a pattern of triangles that looks the same in zoomed-in or zoomed-out views.
The image on the top shows DNA molecules that have self-assembled into a Sierpinski triangle pattern. The graphic on the bottom shows the fractal pattern
The smallest electric motor in the world, devised by physicists at UC Berkeley, is based on the shuttling of atoms between two metal droplets---one large and one small---residing on the back of a carbon nanotube. An electric current transmitted through the nanotube causes atoms to move from the big to the small droplet. In effect, potential energy is being stored in the smaller droplet in the form of surface tension.

Abstract: This article introduces the concept of distributed economies (DE) as a fresh strategy to guide industrial development towards becoming more sustainable. The concept calls for a transformation in the industrial system towards DE departing from the socio-economically and environmentally unsustainable dynamics associated with large-scale, centralised production units that are favoured by neoclassical economic drivers. With DE, a selective share of production is distributed to regions where a diverse range of activities are organised in the form of small-scale, flexible units that are synergistically connected with each other and prioritise quality in their production. However, rather than the total abolishment of large-scale production, our argument concentrates on finding a renewed balance between large- and small-scale and between resource flows that take place within and across regional boundaries. Other desirable characteristics of production units compatible with DE are elaborated. The paper concludes by calling for the deployment of the vast amount of globally and regionally available knowledge for the formation of regionally adapted strategies to create dynamically "self-organizing" business environments.
Marginal Lands In Europe-Causes Of Decline, Basic & Appl. Ecol.
Excerpt: This article analyses the mechanisms behind changes in agricultural land use. Intensification of land use on the one hand, and abandonment on the other have had important consequences for landscape and biodiversity. The basic mechanism behind it is a change in the relative prices of inputs and output. In this sense the general economic developments have been determining the changes in agricultural land use. In Western Europe, the rapid increase in the opportunity costs of labour was the main factor behind mechanisation and intensification of agriculture. (...)

Great Extinction Came in Phases, BBC News
Excerpt: The greatest mass extinction recorded in Earth history did not occur as a result of one single cataclysmic event.
A joint UK-Chinese team tell Nature magazine the disaster that befell the planet 250 million years ago must have happened in phases.
Their conclusion is based on the abundance of "organic fossils" found in rocks at Meishan in southern China.
These suggest there were at least two episodes to the mass die-off that saw up to 95% of lifeforms disappear.
The Dynamics Of Genetic And Morphological Variation On Volcanic Islands, Proc. Biol. Sc.
Excerpt: Oceanic archipelagos of volcanic origin have been important in the study of evolution because they provide repeated natural experiments allowing rigorous tests of evolutionary hypotheses. Ongoing volcanism on these islands may, however, affect the evolutionary diversification of species. Analysis of population structure and phylogeographic patterns in island populations can provide insight into evolutionary dynamics on volcanic islands. We analysed genetic and morphological variation in the gecko Tarentola boettgeri on the island of Gran Canaria (...). This suggests that historically caused patterns in morphology may be overwritten by natural selection within 2 million years.

Galactic Pancake Mystery Solved, BBC News
Astronomers have figured out why a series of small galaxies surrounding the Milky Way are distributed around it in the shape of a pancake.
Theorists believed that the eleven dwarf galaxy companions should have a diffuse, spherical arrangement.
But a University of Durham team used a supercomputer to show how the galaxies could take the pancake form without challenging cosmological theory.
The results were presented at the UK National Astronomy Meeting.
Simulations show how galaxies evolve under dark matter influence
US Drivers Fume As Gas Prices Soar, BBC News
There are increasing signs that US motorists are changing their driving habits in the face of record prices at the fuel pumps.
While the US love affair with the motor car is far from over, consumer dismay has greeted the latest predictions that the average price of petrol will hit $2.35-a-gallon during the peak summer driving season.
That is cheap fuel by European standards, but represents a substantial spike in the US, where motorists were paying some 40 cents less last summer.
Sales of gas-hungry sport utility vehicles and pick-ups are stalling, while drivers are taking drastic steps to cut down on expenses. (...)
There may be little sympathy in Europe, but US drivers are feeling the pinch ]

Terrorist Attacks on Reactor Pools, NY Times
Excerpts: A report just released by the National Academy of Sciences bears two disturbing revelations. The cooling pools for nuclear waste at some reactor sites may be far more vulnerable to a devastating attack by terrorists than federal regulators are willing to admit. And the Nuclear Regulatory Commission is operating in a hermetically sealed cocoon that makes it difficult for anyone - even the academy, armed with a Congressional mandate - to tell whether the public is adequately protected.
Nuclear Plants Warned Of Terrorist Fire Hazard, Nature News
Excerpts: Power plants must do more to protect their radioactive waste from possible terrorist attacks, according to a committee of the National Academy of Sciences, the leading US scientific society.
The danger, according to the report, is that terrorists might start a fire in a power plant's spent-fuel pool, where radioactive waste is stored after it is removed from the reactor. "Under certain conditions a substantial amount of fission products can be released in a pool fire," says Carl Alexander, a materials scientist at Battelle Memorial Institute in Columbus, Ohio, and a member of the committee.
