Through photosynthesis, green plants and cyanobacteria are able to transfer sunlight energy to molecular reaction centers for conversion into chemical energy with nearly 100-percent efficiency. Speed is the key - the transfer of the solar energy takes place almost instantaneously so little energy is wasted as heat. How photosynthesis achieves this near instantaneous energy transfer is a long-standing mystery that may have finally been solved.
Photosynthesis Takes A Leaf Out Of The Quantum Book, PhysicsWeb 
Excerpts:  The quantum route: An artist's impression of how energy reaches the "reaction centre" for photosynthesis, simultaneously "sampling" different routes as it travels through the green pigment chlorophyll. This causes regular "quantum beats" like water ripples when the energy signals are measured using spectroscopy. (Image courtesy: Gregory S. Engel, UC Berkeley) |
Quantum computers and blades of grass have more in common than you might think. Physicists in the US have shown that electrons involved in photosynthesis reactions "sample" different energy-level routes in much the same way quantum-computer algorithms can -- at least in theory -- quickly search through unsorted databases. The researchers claim that the discovery could explain how photosynthesis can proceed at efficiencies unparalleled in manmade solar cells (...).
Biophysics: Quantum Path To Photosynthesis, Nature
Excerpts: But where does quantum mechanics, let alone quantum computing, fit in here? The mechanism of energy transfer through chromophore complexes has generally been assumed to involve incoherent hopping - that is, seemingly uncoordinated movement in a 'random walk' with a general downhill direction - either between individual chromophores, or between modestly delocalized energy states spanning several chromophores. The energy transfer is determined by quantum-mechanical states and their overlaps, to be sure, but there is nothing inherently 'quantum' or wave-like in the process itself.
Evidence For Wavelike Energy Transfer Through Quantum Coherence In Photosynthetic Systems, Nature
Excerpts: Photosynthetic complexes are exquisitely tuned to capture solar light efficiently, and then transmit the excitation energy to reaction centres, where long term energy storage is initiated. The energy transfer mechanism is often described by semiclassical models that invoke 'hopping' of excited-state populations along discrete energy levels. Two-dimensional Fourier transform electronic spectroscopy has mapped6 these energy levels and their coupling in the Fenna-Matthews-Olson (FMO) bacteriochlorophyll complex, which is found in green sulphur bacteria and acts as an energy 'wire' connecting a large peripheral light-harvesting antenna, the chlorosome, to the reaction centre.

Shape-Shifting 'Smart Dust' May Explore Alien Worlds, New Scientist
Excerpts: Thousands of miniscule wireless sensors, or "smart dust", could one-day be used to explore other planets, swirling across the landscape by subtly altering their shape. At least, that's the exotic vision put forward in new computer simulations. Several different research groups are developing tiny smart dust devices (see March of the motes). Each is a few cubic millimetres in volume and can perform simple sensing tasks and relay messages to other such devices over distances of less than a metre.
Euler's Beautiful Equation, Science News
Excerpts:  The famous mathematician Leonhard Euler was born 300 years ago. Portrait by Johann Georg Brucker/Wikipedia |
"Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don't know what it means. But we have proved it, and therefore we know it must be the truth." Benjamin Pierce, a Harvard mathematician, after proving Euler's equation, ei Pi = -1 , in a 19th-century lecture. The equation weaves together four seemingly unrelated mathematical numbers, e, Pi, i, and -1, in an astonishingly simple way.
On the Kolmogorov-Chaitin Complexity for short sequences, arXiv
Abstract: A drawback to Kolmogorov-Chaitin complexity $(K)$ is that it is uncomputable in general, and that limits its range of applicability. Another critique concerns the dependence of $K$ on a particular universal Turing machine $U$ for which predictions for short sequences -shorter for example than typical compiler lengths- can be arbitrary. In practice one can approximate it by computable compression methods. However, such compression methods do not provide a good approximation for short sequences. Herein is suggested an empirical approach to overcome the problem that compression approximations do not work well for short sequences.
Additionally, our results demonstrate that there is a strong correlation in terms of sequence frequencies across the output of several systems including such abstract systems as cellular automata and Turing machines, as well as repositories containing a sample of real-world information such as images and human DNA fragments. Our results suggest that behind all such systems is a shared -probably unique- distribution in accordance with what would be predicted by algorithmic probability.
If You Can Make It There¡K Cities Are The Greatest Generators Of Innovation And Wealth, Scientific American
Excerpts:  Image: ? ISTOCKPHOTO/DANIEL STEIN
SOCIAL HUB: A new mathematical model shows how different infrastructure and social activity patterns grow along with a city's population; the model could aid city planners in maximizing a city's productivity, while minimizing things like crime and poverty. |
Cities create a sort of "urban economic miracle," says study co-author Luis Bettencourt, a research scientist in Los Alamos National Laboratory's Theoretical Division. "When you integrate all these people and all these activities and the struggle to make a living, total productivity increases," he says. Bettencourt and his colleagues at Arizona State University (A.S.U.), Dresden University of Technology in Germany and New Mexico's Santa Fe Institute, modeled the growth of a city according to three categories of factors: material infrastructure (road surfaces, electrical cable, etc.),(...)
Pipeline Develops Prediction Engine For Switching Traders Into The Best Performing Algorithm, Wall Street & Technology: Blog
Excerpts: After expelling third-party algorithms one month ago from passing through its block market, Pipeline Trading Systems LLC has invented a method of predicting the performance of third-party algorithms that its customers can still access through DMA platforms. On Friday, Pipeline said it has created an Algorithm Switching Engine that is able to predict the performance of third-party algorithmic trading strategies and offer these algorithms to traders while they are waiting for a match in the block marketplace.
Forecasting Exchange Rate Better With Artificial Neural Network, J. Policy Modeling
Excerpts: This paper brings into play neural network to make one-step-ahead prediction of weekly Indian rupee/US dollar exchange rate. We also compare the forecasting accuracy of neural network with that of linear autoregressive and random walk models. (...) we find that neural network has superior in-sample forecast than linear autoregressive and random walk models. Neural network is also found to beat both linear autoregressive and random walk models in out-of-sample forecasting. This finding provides evidence against the efficient market hypothesis and suggests that there exists always a possibility of extracting information hidden in the exchange rate and predicting it into the future.

Almost Human, and Sometimes Smarter, NY Times
Excerpts:  From top, Estuko Nogami/Kyoto University; Tetsuro Matsuzawa; Michael K. Nichols/National Geographic; Estuko Nogami/Kyoto University From the top, Ayumu, a 6-year-old male, shows foresight in stacking blocks; chimps can outperform humans at some memory tasks; they use simple tools like twigs to dig out ants and termites, and rocks to crack open nuts. |
For example, chimps on their own would not sit at a computer responding with rapid touches on the screen as a test of their immediate memory. Videos of their doing just that at Kyoto University in Japan especially impressed the symposium scientists. Tetsuro Matsuzawa, a Kyoto primatologist, described a young chimp watching as numbers 1 through 9 flashed on the computer screen at random positions. Then the numbers disappeared in no more than a second.

Excerpts:
 GOLDENROD: The neocortex, the seat of human reasoning, is an astonishing organ. Its 30 billion or so neurons are organized in six layers, each about the thickness of a playing card. The picture here, an image from the Blue Brain Project, shows neurons from the fifth layer. The Blue Brain Project is a joint research effort by IBM and the Ecole Polytechnique F?d?rale de Lausanne to study the brain using IBM's Blue Gene supercomputing system.

Turing's behavioral framing of the problem has led researchers away from the most promising avenue of study: the human brain. It is clear to many people that the brain must work in ways that are very different from digital computers. To build intelligent machines, then, why not understand how the brain works, and then ask how we can replicate it? My colleagues and I have been pursuing that approach for several years. We've focused on the brain's neocortex, and we have made significant progress in understanding how it works.
Retinal Implant Learns To Polish The Picture, New Scientist
Excerpts:  Having a user train their retinal implant could help make the picture clearer (Image: Rolf Eckmiller) |
In their system, a camera feeds information to a "retina encoder" - software that mimics the image processing done by a healthy retina. "It has hundreds of different parameters [that can] be properly tuned," says Eckmiller. "But only one setting is appropriate to allow proper perception." So the Bonn team is developing software that learns the correct settings from a user.
Fragile X, Down Syndromes Linked To Faulty Brain Communication, Innovations-report
Excerpt: The two most prevalent forms of genetic mental retardation, Fragile X and Down syndromes, may share a common cause, according to (...). The problem, a crippled communication network in the brain, may also be associated with autism. Although the genetics of the disorders are very different, the end result for the brain seems to be the same, said (...). "It's as if you had every light in your house wired to just one or two switches, rather than having many switches that can be flipped on or off in complex combinations to control the lighting in one room," he said.
Do We Expect Natural Selection To Produce Rational Behaviour?, Phil. Tran. Biol. Sc.
Excerpt: We expect that natural selection should result in behavioural rules which perform well; however, animals (including humans) sometimes make bad decisions. (...) we concentrate on two of them. One explanation is that the outcome is a side effect; what matters is how a rule performs (in terms of reproductive success). Several rules may perform well in the environment in which they have evolved, but their performance may differ in a 'new' environment (e.g. the laboratory). Some rules may perform very badly in this environment. We use the debate about whether animals follow the matching law rather than maximizing their gains as an illustration. (...)
Wired For Sound: How The Brain Senses Visual Illusions, ScienceDaily
Excerpts: In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers (...) have found new evidence of rapid integration of auditory and visual sensations in the brain. (...) When subjects were shown a single flash of light interposed between two brief sounds, many subjects reported seeing two distinct flashes of light. Investigating the timing and location of the brain processes that underlie this illusory effect -- the illusion of seeing two flashes in the presence of two auditory signals, when only one flash actually occurs -- can reveal how information from different senses are integrated in the brain.

Does Medicine without Evolution Make Sense?, PLoS Biol
Excerpts: It is curious that Charles Darwin, perhaps medicine's most famous dropout, provided the impetus for a subject that figures so rarely in medical education. Indeed, even the iconic textbook example of evolutionâ€"antibiotic resistanceâ€"is rarely described as “evolution†in relevant papers published in medical journals [1]. (...) Yet an understanding of how natural selection shapes vulnerability to disease can provide fundamental insights into medicine and health and is no less relevant than an understanding of physiology or biochemistry.

The Genetics of Brain Wiring: From Molecule to Mind, PLoS Biol
Excerpt: What makes some people neurotic or schizophrenic or right-handed or fearless? Are these behavioural differences caused by literal differences in how individuals' brains are wired? If so, what causes those differences? This age-old question of nature versus nurture can be recast in more realistic terms based on our modern understanding of genetics, development, and neuroscience. The challenge in this area is to understand how genotype is mapped to phenotype, not just in terms of the average effects of single genes across populations but also in terms of their combined effects in shaping the phenotypes of individuals.

Novelty and Collective Attention, arXiv
Abstract: The subject of collective attention is central to an information age where millions of people are inundated with daily messages. It is thus of interest to understand how attention to novel items propagates and eventually fades among large populations. We have analyzed the dynamics of collective attention among one million users of an interactive website -- digg.com -- devoted to thousands of novel news stories. The observations can be described by a dynamical model characterized by a single novelty factor. Our measurements indicate that novelty within groups decays with a stretched-exponential law, suggesting the existence of a natural time scale over which attention fades.
A Barrel of Monkey Genes, Science
Excerpts: Before the rhesus macaque sequencing effort, the human and chimpanzee genomes were available, but these tools could not be used to their fullest potential in studies of evolution. When we look at humans and chimpanzees, we are gazing through a very narrow window, because they diverged so recently in evolutionary history. The rhesus macaque, as our next closest relative, is an ideal outgroup for human/chimpanzee comparisons. We now can step back and examine the past 25 million years of primate evolution, identifying genomic similarities and differences between each species.

Human-Specific Changes of Genome Structure Detected by Genomic Triangulation, Science
Excerpts: Knowledge of the rhesus macaque genome sequence enables reconstruction of the ancestral state of the human genome before the divergence of chimpanzees. However, the draft quality of nonhuman primate genome assemblies challenges the ability of current methods to detect insertions, deletions, and copy-number variations between humans, chimpanzees, and rhesus macaques and hinders the identification of evolutionary changes between these species. Because of the abundance of segmental duplications, genome comparisons require the integration of genomic assemblies and data from large-insert clones, linkage maps, and radiation hybrid maps.
Primate's Progress: Macaque Genome Is Usefully Different, Science News
Excerpts:  THIRD COUSIN. Like people and chimps, the rhesus macaque has now had almost all of its genome sequenced. J. Moglia/Science |
The new sequence information already indicates that some normal macaque genes look like human versions associated with diseases. For example, macaque versions of several enzyme genes look like ones that cause phenylketonuria, a condition that causes mental retardation in people. "The macaque-genome sequence will have an important impact on both biomedical research and basic research," (...).
Cargill predicts that the new genome will advance the study of mechanisms underlying infection and immune responses and will boost progress in vaccine development.
Genetics: Mysterious, Widespread Obesity Gene Found Through, Science
Excerpts: The role that obesity plays in diabetes, cancer, and other diseases makes our expanding waistlines one of today's most pressing health problems. Now, on the genetics front, researchers have nabbed a coveted prize: the first clear-cut evidence for a common gene that helps explain why some people get fat and others stay trim. The British team, led by Andrew Hattersley of Peninsula Medical School in Exeter and Mark McCarthy of Oxford University, doesn't know what this gene, called FTO, does.
Bug Versus Bug: Insect Virus Makes A Viable Flu Vaccine, Science News
Excerpts: A new influenza vaccine churned out by caterpillar cells prevents the flu, researchers say. The advance might eventually revolutionize the manufacture of flu vaccine, now produced in chicken eggs in a long, cumbersome process prone to contamination and other failures. After successful safety tests, "this is the first time this ... vaccine has been shown to protect people against the flu," (...).
Immunology: The Education of T Cells, Science
Excerpts: Almost 3 decades ago, a team of immunologists made an intriguing observation. They collected white blood cells called lymphocytes from lymphatic fluid (lymph) that drained the skin or the gut of a healthy sheep, labeled those lymphocytes, and injected them back into the same sheep's bloodstream. To their surprise, the injected cells didn't patrol the whole body: Cells from the skin region returned mostly to the skin, whereas those from the intestine homed mostly back to the gut.
Climate Change: Global Warming Is Changing the World, Science
Excerpts: An international climate assessment finds for the first time that humans are altering their world and the life in it by altering climate; looking ahead, global warming's impacts will only worsen In early February, the United Nations--sponsored Intergovernmental Panel on Climate Change (IPCC) declared in no uncertain terms that the world is warming and that humans are mostly to blame.
Santa Fe Air Taking Steps to Offset Carbon Emissions, Aero-News.net
Excerpts: According to Forest Guardians, the process of planting trees to offset carbon dioxide emissions results in 'carbon neutral' flight since the amount of carbon emitted from a fight will be absorbed by the trees. "Our new carbon offset program uses formulas developed by J. Doyle Farmer, professor at the Santa Fe Institute, in conjunction with United States Department of Energy reports to calculate the number of new trees necessary to offset the amount of carbon dioxide emitted from air travel based upon miles traveled and fuel efficiency," said Forest Guardian Communications Director, Rosie Brandenberger.
Ecology: A Positive Feedback With Negative Consequences, Science
Excerpts: It has long been recognized that isoprene emissions from vascular plants play an important role in atmospheric chemistry (1-3). Recent advances (4, 5) suggest that these emissions--in conjunction with fossil fuel combustion and fertilizer application--may create a positive feedback loop, in which species-specific metabolism causes changes in tropospheric chemistry that in turn affect biological diversity and ecosystem metabolism. About 1% of the carbon captured during photosynthesis by terrestrial ecosystems is returned to the atmosphere as isoprene (6).
Chemistry: Putting Order into Polymer Networks, Science
Excerpts: Microporous materials contain pores or channels with diameters of less than 2 nm--only a little bigger than many molecules. These pores or channels may be used as filters that allow some species through but not others, as containers to isolate or store specific molecules, or as tiny chemical reactors. Chemists have found ways to prepare a wide variety of porous materials, but it has proved difficult to form organic polymer networks with perfectly controlled pore dimensions--until now.
'Emergence Of Life ... Was Not An Accident', The New Mexican
Excerpts: "From a scientific perspective, given how much we don't understand, it's a little bit surprising even that there is life in the world and that it's been here and that it's been basically the same kind of process for almost the entire age of the world," Smith said. "There are all sorts of things that come up for a little while, and then something disturbs them, and they fall apart and they're never seen again. Most of the species that have ever lived in the world are of that kind.
Laws Limit Options When a Student Is Mentally Ill, NY Times
Excerpts: Federal privacy and antidiscrimination laws restrict how universities can deal with students who have mental health problems. For the most part, universities cannot tell parents about their children's problems without the student's consent. They cannot release any information in a student's medical record without consent. And they cannot put students on involuntary medical leave, just because they develop a serious mental illness.
Complex Challenges: Global Terrorist Networks
New Approach To 'War On Terror' Revealed In Study, Innovations-report
Excerpts: Archbishop Desmond Tutu has endorsed calls from one of Britain's leading think tanks for a new approach to global security and, in particular, the 'war on terror'. Commenting on the release of a major new study from Oxford Research Group (ORG), the Nobel Peace Prize laureate said: "This incisive study is radical in the proper sense; it penetrates beneath the surface of the debate in the West over its security to demonstrate that the real threat to global peace and stability lies in our failure to recognise our interdependence - that the well-being of the privileged depends on the well-being of the marginalised."(...)
