Weather specialists warned that the strong climatic events which devastated many cities and caused floods in Buenos Aires and La Plata are not a coincidence and will happen more often.
The electric tricycle developed by researchers in La Plata travelled at the beginning of December along Ruta 2 towards Mar del Plata. It was the first long-distance trip and a fundamental test to evaluate its performance and autonomy. It is the first vehicle in Latin America which works with lithium batteries, a mineral which constitutes a clean energy source and which can become an energetic alternative for Argentina.
Geological capture of carbon dioxide has arguments in favor and against and it is in experimental stage. It might permit to capture the CO2 generated in electric power stations and industrial sources and inject it, for example, in deep saline aquifers. A group of scientists studies the interaction of this gas with the water present in aquifers.
Researchers analyze the relation of teachers and media workers with their work subjects and define a new category called “immaterial work”. The research is new in the topic, as it not only analyzes immaterial subjects, but also the work conditions.
An international research project, which focuses in local genus and species, determined that in less than 70 years, the 20 percent of the wall lizard species of the planets will become extinct. In order to carry out the study, an artificial lizard model with microchips was used, as well as a mathematical extinction risk model. The loss of diversity of wall lizards will have consequences for all the food chain.
They are considered a plague and it was demonstrated that the higher the room temperature, the more they eat, change their food and walk faster. That is why they might generate serious consequences on many human activities. Researchers state that, due to the increase in the temperature, black ants, as well as other plagues might be favored and invade new areas or increase their populations alarmingly.
A group of researchers heads a new project in the country which promises to revolutionize the automotive market. Through the use of lithium batteries, scientists from the School of Exact Sciences developed this unprecedented vehicle in a Chinese vehicle. The researchers’ objective is to impose the idea that lithium can be transformed in the near future into an energetic alternative for Argentina.
A vehicle propelled by human and solar energy, developed in the Regional School of Santa Fe of the National Technological University got the second prize in the first Latin American competence of vehicles propelled with solar energy -Atacama Solar Challenge- carried out in Atacama Desert, in the north of Chile. It has a torpedo-like shape and three clean energy sources and it completed the 1,060 kilometers of the race with excellent results.
A research made by scientists from the Conicet and the University says that climate change was not produced cyclically during thousands of years and that its main cause is solar radiation. According to the researchers’ hypothesis, global warming won’t be prevented by the human action and its highest peak will be reached in 600 years. Some traces were obtained in Bahía Blanca’s estuary. They will look for others in an expedition to Tierra del Fuego.
People migrations, promoted by the new transport means or due to working reasons, not only permit humans’ transfer, but also the transmission of parasite diseases from one region to another and from one country to another. Dr. Sixto Raúl Costamagna, Professor of Clinical Parasitology of the Universidad Nacional del Sur talked about this phenomenon called “Parasitic disease Globalization”.
The new website contains data about the weather in 16 cities and offers major precision because it works at a minor scale than other similar sites. The information offered goes from humidity and wind-chill factor to the behavior of El Niño, seasonal tendencies and digital animations about possible emanations of Puyehue Volcano. The data is up-dated every 5 minutes, so it constitutes a new scientific development in the weather forecast of Buenos Aires’ southwest.
Electronic Engineers designed a device which permits the user to automate his house. The system enables the modification of the functions according to the necessities of the people who use it. In this way, from a standard mobile phone we can manage activities which go from turning lights on or activate an irrigation system to receiving information about doors’ movements or the activation of fire alarms.
Based on an important statistic database with thermal and rain registers of up to 100 years ago the Professor María Emilia Pérez hold in an interview to InfoUniversidades that “there are not enough elements to talk about climate change in strict sense; but we could say that we are facing variations, fluctuations or climate oscillations which are within the normal parameters”.
A research carried out by specialists from the School of Law states that the globalization of Law and the dissolution of the State generated the creation of a new biopolitical space. The work goes deep into the role of bioethics in the current globalization scenario and, among other key points, analyzes the advance of the international law over the local law, the corporative control over biodiversity and the conversion of social value development into economic and strategic values.
In an interview to InfoUniversidades, Leonardo Boff, Brazilian theologist and ecologist remarked that the universities are governed by research models which try to dominate nature and don’t look for a dialogue with it. He talked about the Letter to the Earth and remarked the necessity of taking advantage of the wisdom of the natives to face future threats. The intellectual, who was also one of the starters of the Theology for Liberation, was winner of the “Right Livelihood Award”, known as the alternative Nobel Prize.
Teachers from the National University of Villa María carry out an investigation about older adults’ experiences. Departing from the increase of longevity and the global population’s ageing, the concept of productivity in this stage in life is analyzed. The first results show their positive view, the wish to do what they want and their willpower to overcome adversity.
Researchers of the UNCuyo warn about “heat island effect” produced by the increment of cement on green spaces and its combination with global warming in cities. That is why they determined the “environmental value” of different spaces to discover how to make them more efficient against heat. This value represents the percentage of solar energy subtracted from the environment and the quantity of heat emitted as sensitive heat. To mitigate the harmful effects they recommend an intelligent planning of open public and private spaces.
En su sede de Trelew, el departamento de Física monitorea la capa de ozono y utiliza instrumentos provistos por la NASA para detectar los niveles de aerosoles en la atmósfera. La información, resultado de las mediciones, es compartida con la agencia norteamericana y con las 300 estaciones de este tipo que existen alrededor del mundo y forman la red “Aeronet”. Los investigadores buscan confirmar el vínculo entre las enfermedades de la piel, como el melanoma -uno de los causantes del cáncer de piel- y los rayos ultravioletas, para que se elaboren planes orientados a la detección precoz y la prevención de estas patologías.
Activadas por el calentamiento progresivo de la Tierra y la deforestación de los bosques, enfermedades peligrosas y exóticas atraviesan las fronteras hasta llegar a regiones en las que no estaban presentes. InfoUniversidades presenta un informe de la UNC en el que se analiza cómo se modifica el mapa de las patologías asociadas con el cambio climático y su impacto en Latinoamérica, y explica qué es la “epidemiología panorámica”, un método que emplea satélites para predecir la aparición de nuevos males. Dengue, peste bubónica, fiebre amarilla, chagas, gripe aviar, babesiosis, cólera, enfermedad de Lyme, ébola, marea roja, leishmaniasis, todas ellas patologías que se propagan con la modificación global del ambiente.
En conjunto con investigadores de otras universidades del mundo, biólogos de la UNC trabajan desde hace 15 años estudiando el impacto que está produciendo el calentamiento global en el continente antártico. Los especialistas cordobeses se focalizan en la caracterización de los efectos en los ecosistemas marinos a raíz del retroceso de los glaciares. Los temas más preocupantes son la consecuencia de la desglaciación forzada del continente en la dinámica del resto del planeta y la pérdida de biodiversidad. Desde 1997 los investigadores vienen detectando cambios en los ecosistemas bentónicos, con especies que desaparecieron parcialmente y otras que se multiplicaron.
Luego de ser distinguido por la UNSJ con el título Dr. Honoris Causa, el economista Mario Rapoport dialogó con InfoUniversidades y aseguró que es un momento crucial para el capitalismo. Comparó la crisis actual con la gran depresión de los años treinta, y señaló a la inequidad social como la causa de la debacle económica-financiera mundial. El economista también habló sobre la devastación de los recursos naturales, y pronosticó que será cada vez peor si el nivel de producción sigue incrementándose.
Premio Nobel de la Paz en 2007, el Dr. Osvaldo Canciani es especialista en meteorología. Fue invitado por la UNSE para disertar en el VII Seminario del día mundial del ambiente y eligió como tema central el cambio climático. En entrevista con InfoUniversidades, opinó sobre la importancia de la información acerca del calentamiento global y la relevancia del aporte de especialistas para tratar problemáticas regionales. "La estadística no sirve, cada región debe hacer lo suyo".
La Facultad de Agronomía colaboró en la creación del Centro Regional de Agrometeorología, una red de estaciones que actualmente cubren 70 kilómetros del partido de Azul y que es única en Iberoamérica. Las investigaciones evidenciaron el impacto del cambio global en la evolución de la temperatura de la región.
Desde hace tiempo el calentamiento global no sólo es un tema que preocupa a los ecologistas. El aumento de las temperaturas beneficiaría a los viñedos situados en las latitudes más altas. Así, la Patagonia se está convirtiendo en la “tierra prometida” para muchos bodegueros. Junto con Australia y Nueva Zelanda, Argentina ya posee el viñedo y la bodega más australes del planeta,
A partir de la interacción entre la radiación ultravioleta y los gases de efecto invernadero, investigadores estudian la modificación del papel regulador del mar sobre la cantidad de dióxido de carbono en la atmósfera. El trabajo de campo se realizó a lo largo de todo el Atlántico, desde el Ártico a la Antártida.
