Under the stairs two by two, I've gone to sleep, and I slip into the car on the beep, the waning crack closed doors. Find a free site, in the subway at eight o'clock, maybe everything will change at last. As I sat deflated me a long sigh and I hear it again, another day, i hooooo!, Ai hooooo! And while the meter starts running all sing i hooo!, In unison, we will work IOHA IOHA!, And like every morning I feel uncomfortable Initially, I feel ridiculous, but only at first because the joy from us we do not yet seem to be joyful and contagious until we sang with enthusiasm, i hooo!, convinced i hooo!, while moving into the metro bowels of the Earth, going to work!, and tunnels, turned into galleries of a mine flood of this music is absurd to reach the depth of our destiny and stop to get off the convoy in a row, walked hand peak, shovel, other trucks and started dragging extract minerals, gems or hideous, it matters because the dim light of lanterns just allows us to distinguish our faces blackened where whites of the eyes gleam, different races and match the songs that never cease, the ai hooo! that is heard loudly, bouncing through the galleries and encourages us to move forward one hour and another until the sweat threatening to replace the flesh and fluids become useless and then change the letter, not the melody, and accompanied us back to the subway car ahead, ai ai hooo hooo!, to return to the surface, home to rest!, and return chant softly, in whispers, so just go from strength. Back at the station, ai ai hooo hooo!, Escalators damaged, home to rest!, And now we went one at a time that is what we are forces and come home shattered, but with this point of hope and go, like every night in our room smells thick, deep breaths to find sleep, for months, and rub his lips with mine.

Magazine Awards
Last Saturday saw the delivery of the Free II Magazine Awards in the library Bertrand de Barcelona. It was a nice simple ceremony that lasted well under seven hours and threatened us Joseph A. Muñoz, director of RDL, at initial presentation.
not missed any of the ingredients of an awards show worth its salt, from emotion Luciana, contagious, upon receiving his award, to the lucid reflections Javier Celaya, especially Outreach Award, and a generous pica-pica washed down with wine and champagne to toast the issue that we were going and to welcome the next year, and confirmed by the organizers.
Little to say I can only thank Free Magazine for allowing me to participate actively in this festival of digital points and give my most sincere congratulations to the winners, especially Luciana Salvador, winner in the category I was nominated, his blog Firefly Forest that I recommend you visit if you have not already done so.
presence I want to thank Peter Herrero, Carmen, David Figueroa, Antonia, Conrad and Sergi Bellver who came to greet me with great kindness. Between all the afternoon hicistéis was special.
And of course, Ane, who managed to overcome the run without jumping out the window, which undoubtedly deserved more than one occasion.
Now, if you allow me, I retire to a corner to mourn a bit, but only a little.

My wife does not like to nag you their strategies and I love her so much that I consumed with curiosity to please you. So I go for a walk, as I requested, and when I return I am prepared dinner.

The sexual developmental gene
Science is one step closer to unraveling the mystery of human sexual development, thanks to the results of research showing how to create male mice without the Y chromosome, through the activation of an ancient gene brain.
Usually, males have a Y chromosome and one X chromosome, while females have two X chromosomes A single gene on the Y chromosome, called SRY, triggers the development of testes in the embryo, and when these begin to form, the rest of the embryo also becomes male.
However, a team of researchers from the University of Adelaide, Australia, and colleagues at other institutions have discovered how to create a male mouse without a Y chromosome, using the activation of a single gene called SOX3, in the developing fetus. The SOX3 is known to be important for brain development, but had not been shown so far that can also launch the process leading to the male.
has also been demonstrated for the first time that some human patients with developmental disorders sexual changes occur in the human version of the same gene.
The Y chromosome contains the SRY gene, which acts as a genetic switch to activate, during embryonic development, the process of becoming male.
SRY gene switch is unique to mammals and is thought to have evolved from SOX3 gene during early stages of their evolution.
In their experiments, Paul Thomas of the Faculty of Biomedical and Molecular Sciences, University of Adelaide, and colleagues have found male mice with two X chromosomes, through artificial activation of SOX3 gene in the developing gonads.
These XX males mice with artificially induced sex change are totally masculine in their physical appearance, in their reproductive structures and their behavior, but are sterile because of their inability to produce sperm.

March 19, 2011 and historical astronomical tides
Super Luna is the perigee, the largest in nearly 20 years. "The last full moon so big and close to Earth as is the case in March 1983," says Geoff Chester of the U.S. Naval Observatory in Washington DC. "It is worth looking at."
The Full Moon vary in size due to the oval shape of the orbit of the moon. Is an ellipse with one side (perigee) about 50,000 miles closer to Earth than the other (peak).
Moons near the perigee are 14% larger and 30% brighter Moons that occur under side of apogee of the orbit of the moon.
"The Full Moon 19 March occurs in less than an hour before perigee, almost perfect coincidence that only happens every 18 years or so, "added Chester.
Desatres and Super Moon perigee

perigee A full moon brings with it a tide of perigee extras, but this is not to worry , according to NOAA. In most places, the moon's gravity pulls at perigee tide waters only a few centimeters (an inch or so) more than normal. Local geography may amplify the effect by about 15 centimeters and not exactly a great flood to the area.
The Moon appears larger when it is shining through objects in the foreground, leading to a "moon illusion" as if it were larger.
Desatres and Super Moon perigee
In fact, contrary some reports circulating on the Internet, do not trigger Moon perigee natural disasters. The super Luna March 1983, for example, went without incident. And Luna December 2008, almost super, also passed harmlessly.

coffee reduces the risk of stroke in women up to 25%, according to a study
Drinking more than a cup of coffee day is associated with between 22 and 25 percent lower risk of stroke compared with those who make less, according to a study by the National Institute of Environmental Medicine at Karolinska Institute in Stockholm (Sweden), which is published in the journal Stroke: Journal of the American Heart Association. "
Drinking more than a cup of coffee day is associated with between 22 and 25 percent lower risk of stroke compared with those who make less, according to a study by the National Institute of Environmental Medicine at Karolinska Institute in Stockholm (Sweden), which is published in the journal Stroke: Journal of the American Heart Association. "
low consumption or no consumption was associated with an increased risk of stroke in a study of 34,670 women between 49 and 83 years who were followed for an average of 10.4 years. Researchers say that although it is too early to change the habits of coffee drinkers, the study could reduce the concerns of some women.
groups of women who reported drinking one to two cups a day, three or four cups or more of five showed similar benefits compared with those who drank less than one cup a day to day. These differences were maintained regardless of smoking, body mass index, history of diabetes, hypertension, alcohol consumption, suggesting that the effects of coffee are not influenced by known cardiovascular risk factors. Researchers collected
data from the Swedish Mammography Group that investigated the association between diet, lifestyle and disease development. The authors collected cases of first stroke occurred between January 1998 and December 2008 by linking the Swedish based hospitals to document a total of 1,680 strokes. As pointed
Susanna Larsson, author of the study, after taking into account other risk factors, coffee consumption was associated with a lower risk of total stroke, stroke and subarachnoid hemorrhage. Small numbers of intracranial hemorrhage could be due to the lack of association with this subtype of stroke. Overall, stroke is associated more As with dietary factors.
food frequency questionnaires makes no distinction between regular and decaffeinated coffee, but decaffeinated coffee consumption in the Swedish population is low.
Larsson notes that the possible pathways by which coffee consumption may reduce the risk of stroke include weakness subclinical inflammation, oxidative stress reduction and improved insulin sensitivity.
"Some women have avoided drinking coffee because they felt they were healthy. In fact, there is growing evidence that moderate coffee consumption may reduce the risk of some diseases such as diabetes, liver cancer and possibly stroke, "concludes Larsson

deciphered the mysteries of 'genome dark'
DNA with genes, which is 95% of the total, more As important pensaba.El albinism, Alzheimer's and cancer have been associated with this material.
A stranger in DNA. Genes, which are considered the body's operating instructions, only represent 5 % of human DNA. Of the remaining 95% do not know almost nothing. However, scientists are discovering that this so-called junk DNA plays a role in many of the characteristics of a living being. Last week released the first compound (enoxacin) that inhibits tumor growth (in cells and mice) acting on the genome dark. The discovery team is due to Manel Esteller, director of epigenetics and cancer biology at the Institute of Biomedical Research of Bellvitge (IDIBELL).
Another condition on which this DNA acts darker albinism. An albino person has mutations in a set of 14 genes that induce changes in pigmentation. However, in a kind of albinism, this condition there is no corresponding gene mutation. In these cases, "the changes occur in parts of that just 95% of intergenic DNA," said Lluís Montoliu, a researcher at the National Center for Biotechnology (CNB-CSIC) in Madrid and author of the discovery. It is, in particular of oculocutaneous albinism type 1, which is associated with a mutation of the tyrosinase gene, which synthesizes melanin. But 25% of people with this condition have no mutations in this gene, but deep in their DNA.
dark DNA has revealed its role in many phenomena. Their action affects the functioning of the X chromosome in women, affects the shape of the hand and been associated with Alzheimer's, multiple sclerosis and type of deafness. "The intergenic DNA could be what makes us different from each other," observes Montoliu. For many changes you have in 5% of DNA that correspond to genes, the differences in the remaining 95% may be more important. Even the difference between species could lie in there. "A human being has many fewer genes than a rice plant, but is much more complex - see Esteller -. The explanation of the difference in the DNA must be dark."
SECRET AGENT "In light of the new results, we need to rethink the concept of gene," says Montoliu. Genes those parts of DNA that contain instructions for the cell to make proteins. In turn, proteins (such as hemoglobin in the blood) work in many life processes. However, the DNA is not the simple sequence of instructions. "If each gene is a word in the book of DNA are very few meaningful words, separated by a lot more meaningless sequences of letters," explains graphically Juan Valcárcel, researcher at the Center for Genomic Regulation (CRG) in Barcelona.

New method to calculate the age of the earth's crust
A new way to calculate the age of the earth's crust has been developed by researchers at the Universities of Bristol and St Andrews .
The continental crust is the main record of conditions on Earth during the last 4,400 million years. Your training changed the composition of the mantle and the atmosphere, and remains a sink for carbon dioxide through erosion. Therefore, the continental crust has played a key role in the evolution of the Earth, however, the timing of its formation remains a subject of considerable debate.
is a widely held belief that young continental crust grew from depleted upper mantle. A common way to assess when it formed a portion of the cortex is to determine the radiogenic isotopic composition of any sample of it, and compare their isotopic signature of depleted mantle. In other words, radiogenic isotopes can be used to calculate the ages of the formation of the studied portion of the cortex, representing that portion when separated from its source in the mantle.
The concept of "old model" has been widely used over the past three decades in studies of the evolution of the crust. However, it is increasingly clear that using the isotopic composition of depleted mantle as the reference for model ages of the generation of continental crust, can result in incomplete interpretations.
In a new study, the team of Bruno Dhuime (University of Bristol) has set up a new methodology for the calculation of model ages, based on the isotopic composition typical of the new continental crust.
ages calculated in this way are significantly lower than the model ages calculated from the isotopic composition of depleted mantle. The new ages obtained agree better with the geological record, which opens new perspectives for studies on the evolution of the crust based on radiogenic isotopes.

A combination of resveratrol and rapamycin inhibits the development of breast cancer, a study
Researchers Lerner Research Institute Cleveland Clinic in the U.S. have discovered that resveratrol, a component of red wine, when combined with the drug rapamycin can have an effect suppressor of tumors on breast cancer cells that are resistant to rapamycin alone.
Research also indicates that the PTEN tumor suppressor gene contributes to the antitumor effects of resveratrol in this combination of treatments. The study results are published in the journal Cancer Letters.
The scientists, led by Charis Eng, studied the effect of the combination of resveratrol, a chemopreventive agent found in many natural compounds with rapamycin on breast cancer cells. Research shows an additive effect between the two drugs on signaling and the development of breast cancer cells.
Eng explains, "Rapamycin has been used in clinical trials as a treatment for cancer. Unfortunately, after a time, cancer cells develop resistance to rapamycin. Our findings show that resveratrol appears to mitigate the resistance drug rapamycin-induced breast cancers, at least in the laboratory. "
If these observations be maintained in clinical facilities, enjoy a glass of red wine or eating a bowl of boiled peanuts, which have a higher content of resveratrol than red wine, before treatment with rapamycin may be a prudent choice.
Rapamycin, an immunosuppressive drug used to prevent rejection of organ transplants has been taken into account for the use of antitumor activity against breast cancer. Resveratrol is a type of polyphenol that is based on the skin of grapes and is a constituent of red wine and has been considered for many uses, regardless of cellular therapies.
Despite the potential for tumor suppression, the efficacy of rapamycin with respect to inhibition differs markedly between cell lines of breast cancer. The researchers measured the effect of resveratrol and rapamycin, alone or in combination on cell growth of three lines cellular human breast cancer.
In all three cell lines tested, the presence of low concentrations of resveratrol and rapamycin was sufficient to induce an inhibition of 50 percent. Although relatively early, these observations might suggest that resveratrol is a powerful medicine to accompany traditional chemotherapy.

Polite Answer To A Tender Invitation
personal experiences influence the effectiveness of drugs, a study
Researchers at the University of Oxford in the UK and the University Medical Center Hamburg-Eppendorf in Hamburg (Germany) used brain imaging to see how thoughts, feelings and experiences of the past a person can have a significant impact on the effectiveness of drugs. The results of their work is published in the journal Science Translational Medicine.
The authors explain that if a patient participates in a clinical trial or receiving treatment in a medical office, a drug with proven biological effects may appear ineffective if an individual is conditioned to make this happen.
The researchers suggest that neural activity in certain brain areas could be controlled as a way of assessing how well a drug is working for a particular patient. Although doctors know that the beliefs and expectations of a person can influence the effectiveness of a drug, there has been little research to clarify the brain mechanisms that control how different expectations actually interact with the biological effects of drugs.
;
The scientists, led by Ulrike Bingel, use the functional magnetic resonance imaging or MRI to examine how bleak or optimistic predictions of a pain treatment alters brain activity in a group of healthy people. The researchers put
advanced thermal stimulator, a device used to induce and assess pain in the laboratory, the lower leg of each volunteer. Before administering a painkiller called remifentamilo participants, the researchers said some of them that the drug would have no effect, other than diminish the pain sensation and some worsening the pain.
those who hoped that the drug had no effect disturbed, these individuals experienced double relief than those who did not expect the drug benefit, but this group actually did get some relief. On the other hand, those hoping that the drug worsened the pain reported that pain had not changed.
examining the brain scans of volunteers, researchers found that the expectation of increased pain was accompanied by increased activation of neurons in the hippocampus, mid-cingulate cortex and medial prefrontal cortex, brain areas that mediate mood and anxiety. A much lower activity was observed in these regions in individuals who expected remifentamilo reduce the pain.
addition, researchers found more neural activity in the anterior cingulate cortex and the striatum of individuals optimistic. Activity in these regions indicates that the mechanisms resulting from the inhibition of pain were involved, making it more difficult than the pain signals from accessing the spinal cord and brain.

an unknown phenomenon Oxygen Vacuum World Oceans 499 Million Years ago
oceans became rich in oxygen as we know now about 600 million years ago, during the last phase of the Ediacaran Period. Now a team of biogeochemical has found evidence that the oceans were re-anoxic (oxygen-poor) some 499 million years ago, shortly after the appearance of animals on Earth. And it remained so for a period of between 2 and 4 million years .
Researchers at the University of California, Riverside, suggest that such anoxic conditions could exist even for a much wider range of time.
Timothy Lyons's team argues that such fluctuations in oxygen levels of the oceans are the most likely cause of the explosive diversification life forms that marked the Cambrian period, made between 540 and 488 million years.
The transition from a sea usually rich in oxygen during the Cambrian, until fully oxygenated sea that we have today was not as simple as has been widely accepted until now. New research shows that the ocean had fluctuations between different degrees of oxygenation. Such fluctuations played an important, perhaps primary in shaping the early evolution of animals on the planet, to promote certain extinctions and clearing the stage for the new bodies take their place. Researchers now
working to find an explanation for this lack of oxygen in the oceans 499 million years ago.
may seem of little interest to society to investigate the causes of a phenomenon so long ago, but the truth is that investigations are made could be useful now and in the near future. Currently, some parts of the world's oceans are becoming poor in oxygen. Chesapeake Bay (surrounded by Maryland and Virginia) and the "Dead Zone" in the Gulf of Mexico are two examples.
"We know that the Earth had similar situations in the past. Knowing the causes and consequences can provide clues essential to what the future has in store for our oceans, "says Benjamin Gill, the research team.

communication between neurons by fields weak electrical
The brain, whether awake, as if asleep, has a lot of electrical activity, and not just individual signals emitted by a neuron or another when they communicate with each other. In fact, the brain is surrounded by innumerable overlapping electric fields generated by the activity of neural circuits of neurons that communicate. A new study reveals these fields are much more important than previously thought. It is possible that, in fact, represent an additional form of neuronal communication.
In other words, neurons generated extracellular fields but these fields fed back to neurons and alter their behavior, although the neurons are not physically connected. So far, it was believed that direct neuronal communication channel was restricted to synapses.
The team discovered by neuroscientist Costas Anastassiou California Institute of Technology (Caltech), suggests the existence of other media-independent neuronal synapses through extracellular space.
extracellular electric fields appear throughout the brain. Are particularly strong in specific brain regions as the hippocampus, which participates in the creation of memories, and the neocortex, the area where memories are stored long term. The constant fluctuations of these fields extracellular are the hallmark of all brains in a good state of any complex organism, and its absence is a clear sign that the brain is in a deep coma or even death.
The discovery made in this study raises an intriguing question: Could some external electric fields have similar effects on the brain? Physics states that any external field can reach the neuronal membrane. "Although the effect of externally imposed fields also depend on the state of the brain," he qualifies Anastassiou. The ability of an externally imposed field may have to influence the brain also depends on the specific brain area in which impinges. Marga

I expect, however, for the sun to rise on the horizon, I need the warm air currents to fly.
With outstretched wings, glide to the Caucasus Mountains, to the platform as a balcony with views overlooking a vertical wall. And I dregs.
My clumsiness on the ground will awake and inclined his head several times, in greeting, like every morning. He, trying to move, rattling the chain makes it left tied to a rock. She looks at me with more loathing than fear, that hurts. His skin is white as a sheet unworn no trace on either side of what happened the day before.
throw the first peck. He ripped a good chunk of meat on the side and everything turns red. He presses his lips, eyes, and only a groan escapes him. I do not mind your pain. The only thing that worries me is devouring the liver every day. And I put my head on his wound until I eat it whole peck peck, leaving nothing without passion and cruelty.
before the day I thought, I need the sun to fly. Also he needs at night, because during sleep the liver will grow back, undo my work so you can start it again the next day. Return.

Cracks
The editorial "The doors of the doer," just published "cracks", a slim volume that includes nine of my series on microstories old. Since I first spoke with Norberto Luis Romero on the possibility of convening a series of microphones with a common theme, the project excites me a lot and I awaited with impatience. It is finally a reality.
are six numbered and signed by the publisher and author. If you feel curious about the physical characteristics and development blog I refer to the editorial "doer doors, where Norberto gives detailed explanations on how it performs its plaquettes.
Finally, I find it difficult to find words to thank Norberto love with which he treated my micros. With the plaquette in the hands think Norberto creativity in their skill and above all in the great love that has set the whole process. Thanks.

What Does A Dreivatives Broker Do?
Lentils
Be right back Samu, I do not take anything, and he looks at his watch, the watch that his father wore when alive, and go down the aisle, toward the high school.
I start up my stopwatch. If I beat my record I can be home in six minutes and start up the hill at a brisk pace, all that I get the legs. Soon I can almost smell the lentils that mom made, as every Monday, the day of lentils.
Hello, well in school, "I can eat a little sooner? is I have to do a job, I'll eat up large chunks of carrot and onion to give me a bit of disgust, but soon put me, please, to history, mother of history and look at the digital clock because when I was growing up we all had clocks that told you the time with numbers, even more ruthless than the hands. I get up from the table, I have no fruit, lentils and mom served my brothers and I remember that Dad hates to not be home when it comes, but I think it does not appear that Samuel's father cared very little that I would to like his son that he did not come home for three nights.
I leave home in a hurry, almost no time to restart the timer that I set the pace like a metronome. When I get to school I find sitting on a railing Samu under the shed where we have often parked the bikes, looking down. I sit beside him, I'm here, but he ignored me, only looks at his hands, like counting the fingers, ensuring that they remain ten.
