Política científica colombiana será discutida en la Universidad de Harvard y el MIT

Eltiempo.com
Noviembre 7 de 2005

El certamen, cuyo título es ‘Ciencia, Tecnología e Innovación en Colombia 2005’, es organizado por El Coloquio Colombiano.

Esta es una organización estudiantil de la Universidad de Harvard y el Instituto de Tecnología de Maassachusetts (MIT, por su sigla en inglés). Fundada hace nueve años, su “propósito es crear espacio académico abierto para discutir los temas colombianos”.

Dentro de la conferencia, que se realizará el 18 y el 19 de noviembre, se discutirán los siguientes temas:

  • El diagnóstico del estado de la Ciencia y la Tecnología en Colombia.
  • Cómo capitalizar la exportación de recursos humanos calificados.
  • Áreas con ventaja competitiva para Colombia.
  • Soluciones alternativas dadas las restricciones existentes.

De acuerdo con los organizadores, “el rápido ritmo del avance tecnológico, la globalización y las reformas económicas están creando cambios dramáticos en la estructura de las economías y en los mercados laborales a través del mundo.

La investigación y la educación son cada vez más valoradas mientras la ‘economía del conocimiento’ encuentra su lugar y la fragmentación de los procesos de producción trae competencia global a cada aspecto de la economía.

Dos de los principales factores para determinar la capacidad de un país en este contexto son los niveles de desarrollo científico y tecnológico y la preparación y adaptabilidad de la fuerza de trabajo.

“Colombia es un país en desarrollo con deficiencias en aspectos socioeconómicos y tecnológicos. Aunque lo anterior conlleva un tono de urgencia, la contribución que puede hacerse por desarrollos tecnológicos podría ofrecer soluciones sostenibles para muchos de los desafíos socioeconómicos que enfrenta. De ahí la importancia de organizar y comunicar los esfuerzos de los investigadores locales y en el exterior, las instituciones gubernamentales, los establecimientos académicos y los empresarios interesados en promover la investigación y la innovación en Colombia”.

El certamen contará con la participación de altos representantes del Gobierno colombiano: Santiago Montenegro, Director del Departamento de Planeación Nacional; Maria del Rosario Guerra, Directora de Conciencias; Hernando José Gómez, jefe de negociadores para el TLC; de organismos multilaterales: Guillermo Perry, Economista en Jefe para Latinoamérica y el Caribe del Banco Mundial. Así mismo, participarán  renombrados académicos e industriales: Karen Polenske, Directora del Grupo de desarrollo Internacional y Planeación Regional de MIT; Carlos Angulo, Director de la Universidad de los Andes; Lindsay Lowell, Director de Estudios de Política del Instituto de Migración Internacional de la Universidad de Georgetown; Miguel Rueda, Presidente de Epsifarma, entre otros.

La conferencia está organizada en los siguientes páneles:

  • Panel 1. Estado actual de la ciencia y la tecnología en Colombia. El tipo y la calidad de la investigación que se lleva a cabo en Colombia serán evaluadas. Así mismo, será presentada información sobre las instituciones públicas y privadas que llevan a cabo investigación,  sus áreas de estudio y recursos, así como sus planes en el futuro inmediato.
  • Panel 2. Capitalizando la fuga de cerebros. La carencia de recursos en Colombia en comparación con los de los países desarrollados genera una fuga de cerebros temporal o permanente. Este fenómeno crea ventajas y desventajas para el país. El panel abordará las características y efectos económicos de la diáspora.
  • Panel 3. Áreas de vantaja competitivas. Un primer paso para hacer a Colombia competitive mundialmente  es identificar áreas en las cuales Colombia puede tener ventajas intrínsecas a fin de competir en la economía global.
  • Panel 4. Soluciones alternativas. Una vez se determine el estado de la ciencia y la tecnología en Colombia, así como las áreas en las que sería más competitiva, la pregunta natural sería: ¿cuáles son los mecanismos necesarios para promover este desarrollo? Este panel enfatizará en proponer soluciones concretas y creativas para los problemas existentes. Se enfocará en soluciones viables dado el estado actual de recursos en Colombia.

  • Acidifying Oceans Add Urgency To Carbon Dioxide Cuts - It's not just about climate change anymore. Besides loading the atmosphere with heat-trapping greenhouse gases, human emissions of carbon dioxide have also begun to alter the chemistry of the ocean. The ecological and economic consequences are difficult to predict but possibly calamitous, warn a team of chemical oceanographers, and halting the changes already underway will likely require even steeper cuts in carbon emissions than those currently proposed to curb climate change.
  • Looking For The Founatain Of Youth? Cut Your Calories, Research Suggests - In addition to reducing one's risk for many common diseases, new research found that calorie restriction may slow the aging process. Calorie restriction has long been shown to slow the aging process in rats and mice. Calorie restriction - cutting approximately 300 to 500 calories per day - had a similar biological effect in humans, and, therefore, may slow the aging process.
  • Rocketing Through Water: Space-age Swimsuit Being Tested At NASA - Swimmers around the world are breaking records this year like never before, including at this week's U.S. Olympic trials. Some attribute it to extensive training as athletes prepare to compete at this summer's games in Beijing. Others say one factor may be a new swimsuit -- a space-age swimsuit made of fabric tested at NASA.
  • Calpain Inhibitors Never Forget: Improving Memory In Alzheimer's Disease Mice - Overactivation of proteins known as calpains, which are involved in memory formation, has been linked to Alzheimer disease. Researchers have now shown that two different drugs that inhibit calpains can improve memory in a mouse model of Alzheimer's disease, leading them to suggest drugs that target calpains might stop or slow down the memory loss that occurs as Alzheimer's disease progresses.
  • Rare Plants And Endangered Species Such As Tigers At Risk From Traditional Medicine - Two reports from TRAFFIC, the world's largest wildlife trade monitoring network, on traditional medicine systems in Cambodia and Vietnam suggest that illegal wildlife trade, including entire tiger skeletons, and unsustainable harvesting is depleting the region's rich and varied biodiversity and putting the primary health care resource of millions at risk.
  • Woman Aquires New Accent After Stroke - A woman in southern Ontario is one of the first cases in Canada of a rare neurological syndrome in which a person starts speaking with a different accent, researchers reported in the Canadian Journal of Neurological Sciences.
  • Wild Orangutans Declining More Sharply In Sumatra And Borneo Than Thought - Endangered wild orangutan populations are declining more sharply in Sumatra and Borneo than previously estimated, according to new findings. Although other threats to orangutan survival exist, such as hunting in agricultural areas where human-orangutan conflicts exist, the biggest by far is forest destruction associated with the burgeoning palm oil industry in Indonesia and Malaysia.
  • Statins Have Unexpected Effect On Pool Of Powerful Brain Cells - Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells known as glial progenitor cells that are important to brain health as we age, scientists have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.
  • Bee Disease Still A Mystery, Despite New Advances In Undersanding Common Virus - Scientists are one step closer to understanding the recent demise of billions of honey bees after making an important discovery about the transmission of a common bee virus. Deformed wing virus is passed between adult bees and to their developing brood by a parasitic mite called Varroa destructor when it feeds. However, new research suggests that the virus does not replicate in Varroa, highlighting the need for further investigation.
  • Endocrinology: Understanding The Genetics Of Congenital Hyperinsulinism - A number of congenital disorders characterized by low blood sugar levels (hypoglycemia) as a result of excessive secretion of the hormone insulin are collectively known as congenital hyperinsulinism.
  • New Technique Produces Genetically Identical Stem Cells - Cells from mice created using genetically reprogrammed cells can be triggered via drug administration to enter an embryonic-stem-cell-like state without the need for further direct genetic manipulation. This technical advancement enables creation of large numbers of genetically identical cells that can be reprogrammed to an embryonic-stem-cell-like state simply by exposure to a drug. Researchers can exploit such cells to decipher and improve the reprogramming process.
  • Don't Count On Long-term Success In Climate Policy, Warns Paper In Decision Analysis - Long-term climate change policy in the US and abroad is likely to change very slowly, warns a researcher who calls for stronger short-term goals to reduce carbon emissions. Although staging climate change policy decisions over time would seem to make sense, researchers point out that the tendency of U.S. and international policy to change extremely slowly requires front-loading the painful decisions.
  • Mining For Molecules In The Milky Way - Scientists are prospecting in a rich molecular cloud in our Milky Way Galaxy. They seek to discover new, complex molecules in interstellar space that may be precursors to life. As molecules rotate and vibrate, they emit radio waves at specific frequencies. Each molecule has a unique pattern of such frequencies, called spectral lines, that constitutes a "fingerprint" identifying that molecule. Laboratory tests can determine the pattern of spectral lines that identifies a specific molecule.
  • Blood Vessel Inhibitor Shows Promise Against Metastatic Thyroid Cancer - Thyroid cancer that has spread to distant sites has a poor prognosis, but an experimental drug that inhibits tumor blood vessel formation can slow disease progression in some patients, according to a study in the New England Journal of Medicine.
  • Volcanic Activity Shaped Mercury After All - Planetary geologists have determined that volcanism played a central role in forming Mercury's surface. The evidence of volcanic activity, published in Science, lends important insights into Mercury's geologic history.
  • Bringing Stability To The Protein Defective In Phenylketonuria - Phenylketonuria is an inherited disease characterized by progressive mental retardation and seizures because the individual is deficient in the protein PAH. Most of the genetic mutations that cause PKU do so because the PAH protein that is generated by the mutated gene is not stable enough to function. New data now suggest that it might be possible to stabilize the mutated PAH protein in individuals with PKU such that it can function normally.
  • Insights Into Tissue Only Micromillimeters Thick With Help From New High-Tech Robot - "TIGA," the new high-tech imaging center at the University of Heidelberg provides deep insights: a high-tech robot makes it possible for the first time to automatically reproduce and evaluate tissue slices only micromillimeters thick -- an important aid for researchers in understanding cancer or in following in detail the effect of treatment on cells and tissue.
  • Clinicians Should Consider Economic Impact Of New Interventions, According To New Report - Cancer clinicians should understand and consider the economic impact of new interventions, which often have substantial costs, according to a new report.
  • Agriculture Linked To Frog Sexual Abnormalities - A farm irrigation canal would seem a healthier place for toads than a ditch by a supermarket parking lot. But scientists have found the opposite is true. In a study with wide implications for a longstanding debate over whether agricultural chemicals pose a threat to amphibians, zoologists have found that toads in suburban areas are less likely to suffer from reproductive system abnormalities than toads near farms -- where some individual animals had both testes and ovaries.
  • Bone Marrow Alternative: Stem Cells From Umbilical Cord May Be Used To Treat Hepatic Diseases - Researchers from the Universities of Granada and León have shown that mononuclear blood cells from human umbilical cord can be an effective alternative to bone marrow. This work, to be published in the journal Cell Transplantation, could potentially mean a great advance in regenerative hepatic medicine.
  • Mercury's Surface Dominated By Volcanism And Iron-deficiency - Multispectral data on the composition of rock untis of the surface of Mercury show a widespread role for volcanism and an apparent deficiency in iron in the rocks' minerals.
  • Women Over 90 More Likely To Have Dementia Than Men - Women over 90 are significantly more likely to have dementia than men of the same age, according UC Irvine researchers involved with the 90+ Study, one of the nation's largest studies of dementia and other health factors in the fastest-growing age demographic.
  • Undergraduates Forge New Area Of Bioinformatics - A group of undergraduate students have forged a new area of bioinformatics that may improve genomic and proteomic annotations and unlock a collection of stubborn biological mysteries. Their work will be published in the journal Genome Research.
  • Scientists Set Out To Measure How We Perceive Naturalness - Scientists at the National Physical Laboratory are working towards producing the world's first model that will predict how we perceive naturalness. The results could help make synthetic products so good that they are interpreted by our senses as being fully equivalent to the "real thing," but with the benefits of reduced environmental impact and increased durability.
  • Music Went With Cave Art In Prehistoric Caves - Thousands of years later, we can view stone-age art on cave walls, but we can't listen to the stone-age music that would have accompanied many of the pictures. Researchers report that the most acoustically resonant place in a cave -- where sounds linger or reverberate the most -- was also often the place where the pictures were densest. In many sites, flutes made of bone are to be found nearby.
  • Seizures In Newborns Can Be Detected With Small, Portable Brain Activity Monitors - Compact, bedside brain-activity monitors detected most seizures in at-risk infants. That means the compact units could assist clinicians in monitoring for electrical seizures until confirmation with conventional EEG, the researchers assert in an article in Pediatrics.
  • Puzzle In The Control Of Cell Division Unraveled - A puzzle in the control of cell division, one of the most fundamental processes in all biology, has been unraveled. Although the steps of cell division are familiar to all pupils studying biology in schools, the details of how cell division is controlled and errors avoided have still to be sorted out.
  • Coronary Arterial Calcium Scans Help Detect Overall Death Risk In The Elderly - Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study in the Journal of the American College of Cardiology.
  • Researchers Use Supercomputer To Track Pathways In Myoglobin - Myoglobin is responsible for oxygen storage in cells. But how does oxygen travel through the solid protein wall to be anchored by an iron atom deep within the protein? Scientists have now provided a computational solution to the decades-old puzzle.
  • Weight Watchers Vs. Fitness Centers - The nationally known commercial weight loss program, Weight Watchers, was compared to gym membership programs to find out which method wins in the game of good health. Researchers examined the real-life experiences of participants to determine which program helps people lose pounds, reduce body fat and gain health benefits.
  • Breast Cancer: How Tumor Cells Break Free And Form Metastases - When tumor cells acquire the capacity to move around and invade other tissues, there is a risk of metastases and cancer treatment becomes more difficult. Scientists have just discovered how breast cancer cells break the bonds that tether them to the tumor.
  • How Cold Sore Virus Hides During Inactive Phase - Now that scientists have figured out how the virus that causes cold sores hides out, they may have a way to wake it up and kill it. Cold sores, painful, unsightly blemishes around the mouth, have so far evaded a cure or even prevention.
  • First Underwater Neutrino Telescope Has Been Constructed - Construction of the first underwater neutrino telescope has just been completed. Since early June, the last two detection lines of Antares have been probing the bottom of the Mediterranean for neutrinos of cosmic origin. There are now 12 detection lines aimed at observing these elementary particles, which provide insight into the most violent phenomena in the Universe.
  • Healthy Or Diseased? Analysis Of Body's Metabolism Sheds New Light On The Question - Scientists have shown that biological indicators for diseases caused or influenced by environmental factors can be detected by the systemic analysis of the body's metabolism (metabolomics). The procedure presented here is also suitable for pre-clinical drug testing and allows for the early detection of possible side effects of a new medication.
  • Researchers Coat Titanium With Polymer To Improve Integration Of Joint Replacements - New research shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone.
  • Depression Ups Risk Of Complications Following Heart Attack, Study Suggests - People who suffer from severe depression following a heart attack might be more likely to experience cardiac complications while hospitalized, according to a new study. "There is good evidence that if a person has depression after a heart attack, they are more likely to die from cardiac causes in the following months and years," said the lead author and assistant professor at Harvard Medical School. "No one had yet studied whether depression impacts cardiac outcomes immediately after a heart attack -- the time we see the most complications."
  • Families With Children Without A Genetic Or Gestational Link To Their Parents Are Functioning Well - The emotional well-being of families where children lack a genetic or gestational link to one or both of their parents -- where the children have been conceived through surrogacy, egg donation or donor insemination -- has long been a subject of debate. Now, scientists have shown that relationships within such families appear to be functioning well, and that there are few differences between them and families in whom children were conceived naturally.
  • Want To Fly? Don't Copy The Birds And The Bees - There is little comparison between the appearance of any winged creatures and that of modern helicopters or jets, despite similar flight patterns. In an era in which engineers are increasingly exploiting designs from nature, understanding this paradox is becoming ever more important. Researchers have studied the reasons behind these differences in aerodynamics and concluded that scientists should, in this instance, be more hesitant before imitating nature.
  • Topical Oral Syrup Prevents Early Childhood Caries, Study Shows - Dental researchers have reported a significant reduction of tooth decay in toddlers who were treated with the topical syrup xylitol, a naturally occurring non-cavity-causing sweetener.
  • 'Mind's Eye' Influences Visual Perception - Letting your imagination run away with you may actually influence how you see the world. New research has found that mental imagery -- what we see with the "mind's eye" -- directly impacts our visual perception.
  • Circulating Tumor Cells Can Reveal Genetic Signature Of Dangerous Lung Cancers - A microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy.
  • Patriotic New Lilacs Introduced In U.S. - The word evokes memories of promising spring days and visions of colorful, perfumed blooms. Lilacs have long been well-loved staples in America's yards and gardens, and have played a storied role in US history.
  • Following Traumatic Brain Injury, Balanced Nutrition Saves Lives - Clinician-scientists are suggesting an immediate and important change to guidelines used in the care of patients with traumatic brain injury. The researchers say that following traumatic brain injury, patients should be given nutritional supplementation through a gastric feeding tube as soon as possible, which they say can improve their chances of survival by as much as four-fold.
  • Some Fundamental Interactions Of Matter Found To Be Fundamentally Different Than Thought - When an atom collides with a molecule, traditional wisdom said the atom had to strike one end of the molecule hard to deliver energy to it. People thought a glancing blow from an atom would be useless in terms of energy transfer, but that turns out not to be the case. "We have a new understanding of how energy can be transferred in collisions at the molecular scale," said Richard Zare, of Stanford University.
  • Experimental Philosophy Movement Explores Real-life Dilemmas - Imagine a business executive who thinks: "I know that this new policy will harm the environment, but I don't care at all about that -- I just want to increase profits." Is the business executive harming the environment intentionally? Faced with this question, 82 percent of people polled said yes.
  • Einstein Was Right, Astrophysicists Say - Researchers have confirmed a long-held prediction of Albert Einstein's theory of general relativity, via observations of a binary-pulsar star system. Eclipses in a unique system of two dead stars, called pulsars, has shown that one of the pair is 'wobbling' in space - just like a spinning top. The effect, called precession, is precisely as predicted by Albert Einstein and is thus a new and exciting confirmation of his theory.
  • Synthetic Molecules Emulate Enzyme Behavior For The First Time - When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult. Natural catalysts, such as enzymes in the human body that help us digest food, get around this problem by shape-shifting to suit the task at hand.
  • China Earthquake Rare And Unexpected, Says New Study - A new analysis of the setting for last month's devastating earthquake in China by a team of geoscientists shows that the quake resulted from faults with little seismic activity, and that similar events in that area occur only once in every 2,000 to 10,000 years, on average.
