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.

Inmunomarcaje de la ATPasa del retículo sarcoendoplasmático, SERCA 2 (verde) y coloración de Hoechst para núcleos (azul) en células de neuroblastoma humano SH-SY5Y. La principal función de SERCA es bombear Calcio desde el citoplasma hacia el Retículo Endoplasmático, este mecanismo evita que ocurran acumulaciones tóxicas de este ion en el citoplasma celular. Se piensa que su función puede ser alterada por anestésicos volátites como halotano e Isofluorano.

  • Probing exoplanets from the ground: A little telescope goes a long way - NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars. Their work provides a new tool for ground-based observatories, promising to accelerate by years the search for prebiotic, or life-related, molecules on planets orbiting stars beyond our solar system.
  • Poor hand-grip strength associated with poor survival - Poor or declining hand-grip strength in the oldest old is associated with poor survival and may be used as a tool to assess mortality, found a new article. The fastest growing segment of the elderly population is the group older than 85 years, classified as the oldest old.
  • Detecting cancer early - A new testing method is being developed to detect cancer soon after the tumor has formed. It will identify characteristic substances in the blood which accompany a certain type of tumor. The first steps in the development have already been completed.
  • Marijuana ineffective as an Alzheimer's treatment - The benefits of marijuana in tempering or reversing the effects of Alzheimer's disease have been challenged in a new study.
  • Ultra-cold chemistry: First direct observation of exchange process in quantum gas - Considerable progresses made in controlling quantum gases open up a new avenue to study chemical processes. An Austrian research team has now succeeded in directly observing chemical exchange processes in an ultra-cold sample of cesium atoms and Feshbach molecules.
  • Morality research sheds light on the origins of religion - The details surrounding the emergence and evolution of religion have not been clearly established and remain a source of much debate among scholars. Now, a new article brings a new understanding to this long-standing discussion by exploring the fascinating link between morality and religion.
  • Brain location for fear of losing money pinpointed -- the amygdala - Two patients with rare lesions to the brain have provided direct of evidence of how we make decisions -- and what makes us dislike the thought of losing money.
  • Mediterranean diet may lower risk of brain damage that causes thinking problems - A Mediterranean diet may help people avoid the small areas of brain damage that can lead to problems with thinking and memory, according to a new study.
  • Beer is a rich source of silicon and may help prevent osteoporosis - A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Beers containing high levels of malted barley and hops are richest in silicon.
  • Blueberries counteract intestinal diseases - It is already known that blueberries are rich in antioxidants and vitamins. New research shows that blueberry fiber is important and can alleviate and protect against intestinal inflammations, such as ulcerative colitis. The protective effect is even better if the blueberries are eaten together with probiotics.
  • Plant derivative could help refine cancer treatment - Researchers are seeking to refine cancer treatment with an anti-inflammatory plant derivative long used in Chinese medicine.
  • Music, not gadgets, related to teenagers' headaches - Use of most electronic media is not associated with headaches, at least not in adolescents. A study of 1,025 13- to 17-year-olds found no association between the use of computer games, mobile phones or television and the occurrence of headaches or migraines. However, listening to one or two hours of music every day was associated with a pounding head.
  • Carcinogens form from third-hand smoke - Nicotine in third-hand smoke, the residue from tobacco smoke that clings to virtually all surfaces long after a cigarette has been extinguished, reacts with the common indoor air pollutant nitrous acid to produce dangerous carcinogens.
  • Drug shows promise for Huntington's disease - An early stage clinical trial of the experimental drug dimebon (latrepirdine) in people with Huntington's disease appears to be safe and may improve cognition.
  • Smart coating opens door to safer hip, knee and dental implants - Researchers have developed a "smart coating" that helps surgical implants bond more closely with bone and ward off infection.
  • High-altitude climbs may cause corneal swelling, but do not appear to affect vision - Swelling commonly occurs in the corneas of mountain climbers, but does not appear to affect vision at altitudes of up to 6,300 meters (about 20,670 feet), according to a new study.
  • Will earlier springs throw nature out of step? - The recent trend towards earlier UK springs and summers has been accelerating, according to a new study. The research is the most comprehensive and rigorous assessment so far of long-term changes in the seasonal timing of biological events across marine, freshwater and terrestrial environments in the UK.
  • Depressed people feel more gray than blue - People with anxiety and depression are most likely to use a shade of gray to represent their mental state. Researchers describe the development of a color chart, the Manchester Color Wheel, which can be used to study people's preferred pigment in relation to their state of mind.
  • Soft drink consumption may markedly increase risk of pancreatic cancer - Consuming two or more soft drinks per week increased the risk of developing pancreatic cancer by nearly twofold compared to individuals who did not consume soft drinks, according to a new study.
  • Enhancing arrest of cell growth to treat cancer in mice - New research has identified a new type of cellular senescence (i.e., irreversible arrest of cell growth) and determined a way to enhance it to suppress prostate tumor development and growth in mice. These data suggest that enhancing this process might provide a new approach for cancer prevention and therapy.
  • How respiratory tubes and capillaries form in flies - Scientists in Spain report on the formation of the small-diameter respiratory tubes of the fly Drosophila -- a process that resembles the development of the finest blood vessels, the capillaries, in mammals.
  • Rab25: a suppressor of tumor formation in intestines? - Colorectal adenocarcinoma accounts for the majority of cases of colorectal cancer. A series of genetic mutations in the cells lining the colon (intestinal epithelial cells) is thought to be the cause of colorectal adenocarcinoma. By studying mouse models of colon cancer and tissue from individuals with colorectal adenocarcinoma, researchers have now identified RAB25 as one gene that might be involved in the formation of colorectal adenocarcinomas.
  • New method for measuring fluid flow in algae could herald revolution for fluid mechanics - Researchers in fluid dynamics have studied algae to illuminate fluid mechanics. One of the researchers said, "Nature has long inspired researchers in fluid mechanics to explore the mechanical strategies used by living creatures. Where better to look for innovative solutions to a technological challenge than to organisms that have had millions of years to devise strategies for related challenges?"
  • Nicotine replacement therapy is over-promoted since most ex-smokers quit unassisted, experts argue - Health authorities should emphasize the positive message that the most successful method used by most ex-smokers is unassisted cessation, despite the promotion of cessation drugs by pharmaceutical companies and many tobacco control advocates, according to a new article.
  • Evolution impacts environment: Fundamental shift in how biologists perceive relationship between evolution and ecology - The traditional view is that ecology shapes evolution. Some research has suggested, however, that evolutionary processes reciprocate by influencing ecology in turn. Now biologists present evidence that ecology and evolution are indeed reciprocally interacting processes, presenting a fundamental shift in our understanding of the relationship between evolution and ecology. The results represent a first significant step in showing that evolution cannot be ignored when studying ecological interactions.
  • Mice shed new light on causes of childhood deafness - Mice with a genetic change that causes progressive hearing loss in children, also have hearing loss because sound waves are not processed properly. The ear's attempts to compensate for hearing loss may, ironically, cause further damage leading to complete hearing loss. These mice will allow detailed research into many forms of deafness, and bring closer the prospects of therapies to slow or halt hearing loss in both children and adults.
  • 'Boutique' fish farms created for Ugandans to combat Lake Victoria's depleted fish supplies - In a unique project to combat depleted fish supplies in Lake Victoria, researchers have established 'boutique' fish farms in small villages around the Lake's shore in Uganda.
  • Complete chemokine profile of a cell - Chemokines are a large group of proteins whose predominant function is to direct cell migration. They regulate many physiological and pathophysiological processes, in particular in the immune system. Researchers have now developed a simple method to efficiently identify all the chemokines produced by a single cell type, something that has not been possible before.
  • Method of the future uses single-cell imaging to identify gene interactions - Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. Researchers have now developed a novel method of interpreting data from single-cell images to identify genetic interactions within biological networks, offering a glimpse into the future of high-throughput cell imaging analysis.
  • More smokers than non-smokers accept HPV vaccination for their daughters - A parent's existing health habits or behaviors, like cigarette smoking, may influence the likelihood that they will have their daughters vaccinated against HPV.
  • Small insect with a big heart: 'Giving' aphids endangered by their selflessness - One of the founding principles of Darwin's theory is that biological evolution has been shaped by the survival of the fittest. Things, however, are not always that simple as researchers have discovered while analyzing the social behavior of aphids. A few aphid species have "soldiers" who stop reproducing and instead contribute to the public good. Not only do they risk their lives to defend the nest from invaders, but they also mend and clean it.
  • Double agent: Glial cells can protect or kill neurons, vision - Scientists have identified a double agent in the eye that, once triggered, can morph from neuron protector to neuron killer. The discovery has significant health implications since the neurons killed through this process results in vision loss and blindness.
  • Better sign of blood vessel narrowing and early coronary artery disease - Cardiologists and heart imaging specialists at 15 medical centers in eight countries have enrolled the first dozen patients in a year-long investigation to learn whether the subtle squeezing of blood flow through the inner layers of the heart is better than traditional SPECT nuclear imaging tests and other diagnostic radiology procedures for accurately tracking the earliest signs of coronary artery clogs.
  • Genes that regulate maternal inflammatory response, bacterial vaginosis and preterm birth related - Researchers have used haplotype tagging (hap-tag) single-nucleotide polymorphisms to study the relationship between genetic predispositions, an environmental factor -- bacterial vaginosis -- and preterm birth.
  • Conservation from space: Landscape diversity helps to conserve insects - Rugged, hilly landscapes with a range of different habitat types can help maintain more stable butterfly populations and thus aid their conservation, according to new findings. This has implications for how we might design landscapes better to help conserve species.
  • People out and about make cities secure - Young people who have experienced threats and violence feel more insecure than others in urban public spaces, especially when alone.
  • Like escape artists, rotifers elude enemies by drying up and -- poof! -- they are gone with the wind - They haven't had sex in some 30 million years, but some very small invertebrates named bdelloid rotifers are still shocking biologists -- they should have gone extinct long ago. Researchers have discovered the secret to their evolutionary longevity: these rotifers are microscopic escape artists. When facing pathogens, they dry up and are promptly gone with the wind.
  • Link between advanced maternal age and autism confirmed - Advanced maternal age is linked to a significantly elevated risk of having a child with autism, regardless of the father's age, according to an exhaustive study of all births in California during the 1990s.
  • The Stars behind the Curtain - Astronomers have obtained a new image of the giant stellar nursery surrounding NGC 3603, in which stars are continuously being born. Embedded in this scenic nebula is one of the most luminous and most compact clusters of young, massive stars in our Milky Way, which therefore serves as an excellent “local†analogue of very active star-forming regions in other galaxies. The cluster also hosts the most massive star to be “weighed†so far.
  • Test could predict which idiopathic pulmonary fibrosis patients will become severely ill - A simple blood test could predict which patients with the lung-scarring disease known as idiopathic pulmonary fibrosis (IPF) are soon to get far worse, an indicator that could one day influence their treatment, according to researchers. Their findings indicate that the body's immune cells attack healthy lung tissue, suggesting that IPF is in fact an immunologic disease.
  • Agricultural scientists turn to a wild oat to combat crown rust - Scientists are tapping into the DNA of a wild oat, considered by some to be a noxious weed, to see if it can help combat crown rust, the most damaging fungal disease of oats worldwide.
  • Month of birth determines who becomes a sports star - The month of your birth influences your chances of becoming a professional sportsperson, an Australian researcher has found. Scientists studied the seasonal patterns of population health and found the month you were born in could influence your future health and fitness.
  • Bees recognize human faces using feature configuration - Bees can be trained to recognize human faces, so long as the insects are tricked into thinking that the faces are oddly shaped flowers, new research shows. The insects use the arrangement of facial features to recognize and distinguish one face from another.
  • Industrial cleaner linked to increased risk of Parkinson's disease - Workers exposed to tricholorethylene, a chemical once widely used to clean metal such as auto parts, may be at a significantly higher risk of developing Parkinson's disease, according to a new study.
  • 'Starving' fat suppresses appetite - Peptides that target blood vessels in fat and cause them to go into programmed cell death (termed apoptosis) could become a model for future weight-loss therapies, say researchers.
  • Older female cancer survivors have added health issues compared to their counterparts - As cancer survivors live longer, questions arise about what kind of care long-term survivors require. A recently study found 245 older married women who survived cancer had more health problems as compared to a sample of 245 married women without cancer.
  • Argonautes: A big turn-off for proteins - Scientists believe they may have figured out how genetic snippets called microRNAs are able to shut down the production of some proteins.
  • Hackers at the movies - Researchers in Ireland have analyzed 50 non-documentary movies from the last four decades featuring hackers and come to some intriguing conclusions about the hacker stereotype with implications for policy makers and education.
