first_imgBy Dialogo November 01, 2011 Chilean Defense Minister Andrés Allamand, together with the under secretary for defense, Oscar Izurieta, and the head of the Joint General Staff, Lieutenant General Hernán Mardones, met with Allamand’s Brazilian counterpart, Celso Amorim, to review both countries’ bilateral agenda. One of the chief topics discussed at the bilateral meeting, held in Brasilia, the Brazilian capital, was the Chilean proposal to create a gradual and proportional schedule for the withdrawal of forces in Haiti. “Chile shares with Brazil a commitment to Haiti and the will to continue collaborating on the stabilization of that country. That entails moving to a phase of greater collaboration on tasks linked to economic development and strengthening institutions. Just as it is unreasonable to press for a hasty and ill-advised withdrawal from Haiti, it is also wrong to extend our presence in that country forever. The idea is to agree on a gradual and proportional departure itinerary, with the aim that this will be the object of talks both with the Haitian authorities and with those of the United Nations,” Defense Minister Andrés Allamand said. During his official visit to Brazil, Minister Allamand will learn at first hand and on site how that country (Brazil) has set up its border surveillance and protection program, both in its technical aspects (radar systems, sensors, and high-tech equipment) and in its operational aspects, where one of the topics of special interest is the articulation of collaborative efforts between the Armed Forces and the police. “The increase of drug trafficking in the region and the southward displacement of areas planted with coca require a joint and multilateral approach to the problem. Brazil has had a plan for controlling its borders for years. Argentina recently implemented the Northern Shield plan, and we’re moving forward on the North Border Plan. Nevertheless, the effectiveness of these plans depends on the capacity for cooperation, trustworthy exchange of information, and adoption of joint measures,” Minister Allamand maintained. In this context, Chile seeks to collaborate actively in this sphere, with the aim of implementing measures that can serve to combat this plague jointly with other countries in the region.last_img read more

first_imgA biological motor has been found, of all places, on the seeds of wild wheat.  A team of German and Israeli scientists watched wheat seeds and found they could dig themselves into the ground.  How can a dry seed, with no muscles, nerves or circulatory system, accomplish such a feat?  It all becomes clear when you look under the awning.    You’ve probably seen the long strands attached to the seeds of grasses like wheat and oats.  These are called awns.  They’re not just decorative; they are actively involved in seed dispersal.  Once the seed drops to the ground, with awns still attached, a remarkable mechanism goes into action.  As the humidity rises and falls throughout the day and night, the awns respond by bending or twisting.    How does the bending take place?  At first, it seemed surprising anything would happen, because the tissues in cross section look uniform under an electron microscope.  The authors, though, found a remarkable feature: a “huge acoustic impedance contrast” in cross section that affects the stiffness of the awn shaft from one side to the other.  In cross section, the shaft resembles the shape of a mushroom with a cap.  The cap portion had twice the Young’s modulus as the stem – a stiffness the equivalent of spruce wood.  As humidity changes, the differential stiffness causes the entire awn to bend.  By analogy, consider how a bimetal strip, like the coil in a thermostat, bends and straightens in response to temperature.  Not only that, “silica tiles stiffen the epidermis and protect the structure as it interacts with the soil.”    So let’s follow the action in the wild.  The seed, awns and all, falls to the ground.  In real time, it might look like nothing is happening.  The seed, after all, is dead; its tissues are removed from any source of nourishment or internal energy.  A time lapse movie, however, shows the seed appearing to spring back to life.  This time, it’s a robotic life exacting its energy from the air.  The alternate bending and unbending of the awns gives a kind of “muscle” to the seed, propelling it along the ground – and even into the soil!    This mechanism for seed dispersal has been known for some time.  What’s new is that the scientists found tiny silicified hairs on the outside of the awns that act like a ratchet – they force the motion to go one way.  As a result, when oriented horizontally, the seed will swim like a frog along the ground.  (They actually said this: “The movement is reversible; thus, the humidity cycle causes a periodic movement of the awns, which resembles the swimming stroke of frog legs.”)  When oriented vertically, the seed acts like a power shovel.  The awns open and close like the handles of a post hole digger.  Meanwhile, those silicified hairs latch onto the soil particles, only allowing the seed to go down, not up.  Thus, the seed works its way deeper and deeper into the soil – safely out of the reach of predators, fire and drought.  “This suggests that the dead tissue is analogous to a motor,” they said.  “Fueled by the daily humidity cycle, the awns induce the motility required for seed dispersal.”    This mechanism is optimized, they said, for the soil environment of the Fertile Crescent, where civilization first began to farm wheat thousands of years ago.  In some kinds of domesticated wheat, the awns are no longer active.  The authors speculated that the length of time since domestication has reduced the function of the awns without removing them entirely.  Because humans now provide the muscle to plow the seeds into the soil, the awns have atrophied.  Apparently “use it or lose it” applies to seed muscle as well as the animal kind.    In their summary, the authors suggested that humans might gain additional nourishment from wheat – food for thought, that is.  The passive-muscle mechanism in wheat seeds might inspire, among other things, new ways to move weed killers where needed:The understanding of this seed dispersal mechanism may help in developing new concepts in weed control.  The microscopic mechanism found to provide motility to the seed may also serve as a model in biomimetic materials research.  Indeed, a hydration-dependent bending movement was recently reported in an artificial system consisting of nano-silicon columns embedded in a hydrogel film.  From a mechanistic point of view, we have discovered a device for movement that is composed of passive elements.  Locomotion is provided by a volume containing nonoriented cellulose crystallites that shortens on drying and pulls the awn like a muscle.  The energy source for this active movement is the daily cycle of air humidity.Maybe someday artificial muscles in robotic devices will work without batteries, extracting the energy they need from the environment – all inspired by the slender filaments on the grass at your feet.1Elbaum, Zaltzman, Burgert and Fratzl, “The Role of Wheat Awns in the Seed Dispersal Unit,” Science, 11 May 2007: Vol. 316. no. 5826, pp. 884-886, DOI: 10.1126/science.1140097.A passive muscle driven by moisture in the air—amazing.  Could a lowly grass figure out that it needed both a tissue differential with the right acoustic impedance to produce bending at the correct Young’s modulus, at the same time that it needed silicified hairs to act as a ratchet?  Without both, this “frog” would swim in place and get nowhere.  And what contractor laid the silica tiles?  Silicon is not a normal part of plant tissue; it had to be guided into place by epidermal cells while the seed was growing.  The fibrils in the awns, also, need to be arranged exactly right to produce the differential impedance.  The arrangement of all the parts needs to be complete before the mechanism will work.  Think of that – then think about the additional wonder that there are more motors, ratchets and machines at work, on a much smaller scale, inside every cell of the plant.    It was nice of the authors to spare us any evolutionary just-so stories about how this all came together by chance.  Their only use of the E word was in reference to human history: “The short evolutionary time since domestication (about 10,000 years), probably allowed the complete loss of awns in several domesticated wheat lines, but not the alteration of the awn structure.”  If so, this is a case of devolution, not evolution.  They actually used the word design twice.*  Anyone believing evolution could design this mechanism needs to eat more whole wheat to provide better nourishment to the brain.    The authors provided a couple of short time-lapse video clips to illustrate the bending action, but the best way to see this is to get a copy of the wonderful Moody Video production called Journey of Life.  The filmmakers made an eye-popping time-lapse sequence of wild oat seeds, which propel themselves by a similar mechanism, but with twisting action instead of bending.  You would swear you were looking at insects crawling along the ground instead of plant seeds.  This and many other ingenious seed-dispersal mechanisms are wonderfully illustrated in this film (also recapped in Part 1 of the trilogy Wonders of God’s Creation).**    Plants may seem passive, anchored to the ground.  In their own ways, though, they get around like world travelers: crawling, climbing, boating, ballooning, launching, helicoptering, hitchhiking and hunting (e.g., Venus flytrap), surprising us each time with their built-in ingenuity.*Anecdote:  One of the authors of the paper works for the Biotechnology Department of the Tel Hai Academic College in Upper Galilee, Israel.  This is in the vicinity where a certain Teacher told some parables about wheat and sowing (e.g., Matthew 13).  He also said, “I tell you the truth, unless a kernel of wheat falls to the ground and dies, it remains only a single seed.  But if it dies, it produces many seeds.” (John 12:24).  He was speaking in reference to the results His impending death would accomplish.**Project:  This article and the Moody films suggest a science project for your junior-high or high-school student.  Many video camcorders have a time-lapse function (sometimes called interval timer).  If you already own one, you have the most expensive part of a good science project.  Look for backyard weeds and grasses with awns or other external structures; for instance, the seeds of filaree (Erodium cicurarium) work like little power drills.  Suggest a hypothesis for how the shape of the seed contributes to its dispersal.  Build a terrarium where you can control the cycles of temperature and humidity using electrical timers, and use the camcorder interval timer to record the action.  Show your video clips with your display at the science fair.  This seems like a sure way to attract the attention of the judges – and the envy of the other students.  Better still, a demonstration of biological design might kindle some thoughts about a Designer.

first_imgWatching molecular machines at work in living cells should be as fascinating as watching a city through a magnifying glass.Observing biological nanotransporters (Science Daily). What if you could watch drawbridges working on the head of a pin? Something like that, but far smaller, works inside your cells. There’s a “nanoporter” that uses ATP to transport cargo in and out of cell membranes. This system is not as simple as A-B-C, even though it has that name.“ABC transporters are fascinating biological nanomachines,” says Lars Schäfer, head of the Molecular Simulation research group [at Ruhr-University Bochum]. These proteins couple the binding and chemical cleavage of ATP molecules, the chemical energy unit of the cell, with the transport of molecules through biological membranes….“Our results show how the binding of ATP molecules induces structural changes in the transporter that are ultimately required to carry substrate molecules through the membrane,” explains Hendrik Göddeke, co-author and doctoral researcher in Lars Schäfer’s group.Study reveals the inner workings of a molecular motor that packs and unpacks DNA (Phys.org). A chromosome remodeler named INO80 is performing onstage at the Ludwig Maximilian University of Munich: on the microscope stage, that is. Researchers at LMU watched the act of “astonishing precision” as it worked on its “heavy-duty reorganizational task” of wrapping DNA around chromatin.Chromatin remodelers have an essential role as they are molecular machines: they unpick and unpack segments of the DNA by sliding nucleosome spools back and forth, replacing individual histones, freeing up the DNA for transcription, and finally compacting it again, when the job is done. Since all of this happens in a highly dynamic fashion, chromatin remodelers enable cells to react rapidly to alterations in their environment – and this holds for brewer’s yeast as well as for human cells.The clouds of spaghetti that keep DNA data safe (Science Daily). Computer systems worry about data breaches, and so do cells. The cell nucleus is like a massive library read by numerous machines. They deliver information to the cytoplasm outside the nucleus, but only certain molecules can get in or out. This article describes some of the data protection systems provided by the Nuclear Pore Complexes (NPCs), some of the most complex machine systems in cells.Molecular machines (Illustra Media)Cells can avoid “data breaches” when letting signaling proteins into their nuclei thanks to a quirky biophysical mechanism involving a blur of spaghetti-like proteins, researchers from the Rockefeller University and the Albert Einstein College of Medicine have shown. Their study appears in the March 23 issue of the Journal of Biological Chemistry….To travel through NPCs, many molecules must be attached to proteins called transport factors (TFs), which act as shuttles that the NPC recognizes. But the NPC faces a challenge: It must accurately recognize and bind to TFs to let them through without admitting unwanted traffic, but it must let them through quickly — in a matter of milliseconds — in order for the cell to be able to do its duties. Proteins known to accurately bind to specific molecules, like antibodies, normally stay stuck to their targets for periods of up to months.“How on Earth do you have the kind of specificity that we see in protein-protein interactions like antibodies, and yet have the kind of speed that we see with water off a Teflon pan?” asked Michael Rout, professor at Rockefeller University who was one of the co-lead authors of the work.The spaghetti trick involves many intrinsically-disordered proteins in the NPC, looking somewhat like strands of spaghetti, making “many quick, transient contacts between transport factors” and nuclear proteins. How can we visualize this? “I can’t think of any analogy in normal life that does what this does,” Rout said. “You’ve got this blur of (amino acids) coming on and off (the transport factor) with extraordinary speed.” Maybe security engineers could learn something from this technique.Scientists map the portal to the cell’s nucleus (Science Daily). In this second article from Rockefeller University about the NPC, Rout did find one analogy:It reminds us of a suspension bridge, in which a combination of sturdy and flexible parts produce a stress-resilient structure, says Michael P. Rout, who led the work together with Brian T. Chait.The pore complex contains 552 component proteins, called nucleoporins, and scientists hadn’t previously known how they all fit together. It took a combination of approaches to assemble a comprehensive map of these pieces.Sadly, after comparing the NPC to lesser systems designed intelligently by humans, Rout ascribes it all to evolutionary chance. “Evolution has enclosed it with a double membrane, the nuclear envelope,” the article says, going on to visualize some unobserved miracles:The pore complex first emerged when single-celled organisms — the only living things at the time — acquired special compartments containing organ-like structures, including the nucleus, which houses the cell’s genetic code.Strings of electron-carrying proteins may hold the secret to ‘electric bacteria’ (Phys.org). This article suggests that some bacteria may have the ability to transfer electrons from the inside to the outside environment, using “micro machines” that turn on the power to extract energy from the environment. “Could a unique bacterium be nature’s microscopic power plant?” asks Moh El-Naggar, scientist at USC. Isn’t it nice to know that bacteria, “wired for survival” as among the smallest organisms on earth, are “highly evolved machines”?Microbiologists, can you please please turn off the obligatory Darwinspeak and just tell us the facts of what you are looking at?
