In an inhospitable environment, guanacos and rheas were their food source; however, researchers are analyzing the possibility that the first inhabitants had incorporated other resources for their survival, such as fishes. With this aim, they identified more than 75 archeological sites were they analyze the characteristics of the elements found such as clay objects and spearheads.
Naked soils and dunes cover a geography that, although inhospitable and rebel can be sustainable too. That is why in Neuquén, researchers of the UNCo cultivate native plants in a nursery to restore degraded areas. Plantations in the field showed a survival level which reaches a 95%. These are 14 species and as objective the research team hopes to reach 30. This value enhancing of autochthonous species, badly called ‘weeds’, was the departing point.
A research carried out in Buenos Aires South-west showed that the anticipated sowing of wheat and its use as forage in semi-dry areas generate direct economic benefits for the producers. The keys of the technique reside in making an early sowing of wheat so that the grass is accumulated and eaten by the animals and in complementing with sorghum, which improves qualitatively the production of meat by hectare and the net incomes.
The most important scientific experiment of all times, known as “God’s machine” generated a great expectation in the scientific world, controversies and a lot of curiosity by the international society.

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.
An institute located at Tandil’s mountains achieved revolutionary advances. Besides exploring how to produce energy through nuclear fusion, among other things, they model flooding, implement Internet devices for electric cooperatives and integrate computing sciences with agricultural production.
It is what scientists from all over the world try to do. Among them there are physicists from the UBA which work on the protons’ accelerator LHC. The “Large Hadrons Collider” is a colossal machine which has a circumference of 27 km., buried at 100 m depth, under the French-Swiss frontier. Its construction took 20 years and cost 6,000 million dollars. After one year and a half of delay by damage, the accelerator produced the collision of protons’ haces which will achieve 40 million particles per second.
A research concluded that rises of the sea level during the Cenozoic -end of the Tertiary and beginning of the Quaternary- in the last 3 million years covered big part of the Amazon’s basin, except for the lands over 100 meters above the sea level. In these islands, also called speciation centers, it merged the fauna diversity that the Amazon rainforest actually has. This hypothesis is the most accepted by the international scientific community.
A research of the National North-East University could perfect a technique of a disease’s DNA extraction caused by Helicobacter pylori from gastric biopsies in order to use it to typify the genes of this bacterium which causes gastritis, ulcers and carcinomas. Great part of the population has them, although it manifests in only a 30% of the affected people. The technique developed permits to eliminate the bacterium and stop the evolution of the disease.
Students of the UNQ will work on making interviews to the family biographic archive of Abuelas de Plaza de Mayo and will sum to the task of reconstructing the life histories of the disappeared or killed people during the last dictatorship. The grand children from “Abuelas” will be able to piece together their parents’ history from diverse documents and interviews which will be recovered by the students with the aim of knowing which their life paths were.
In the city of Bahía Blanca a group of scientists developed an algorism that eliminates the difference between images taken with various cameras. In this way we obtain high quality panoramic images that permit to enjoy landscapes and touristic shows. Diverse touristic attractions in Argentina are already projected to the world through this new technology.
For the first time and thanks to GPS technology the modification of the position of a point in the map could be measured. An Argentinean specialist who participated in the experience explains the system and the reason of the displacements of up to 15 centimeters of cities such as Mendoza and Buenos Aires.
Researchers of the School of Technology and Applied Sciences analyze the impact produced by hydric erosion in the Ruins of Shincal, in Quimivil, Department of London, Catamarca. According to the results of an exhaustive study of the area and its problem the researchers designed a recovering and control proposal which includes bioengineering works. London’s community, based on the proposal, planned the recovering of Shincal, emblematic work which preserves the original inhabitants’ culture.
The UNLP manufactured three purifiers of water contaminated with arsenic to install them in rural schools of General Viamonte, Carlos Casares and Villarino. The purifier designed, developed and elaborated by a team of researchers of the University, is already functioning in an educative institution of Punta Indio and according to school authorities there were obtained “excellent practical and useful results, even to the teaching of our students”.
Faced with the sustained growth of the chicken sector in our country and the excellent perspectives for the next years, researchers of the UNER are studying technological processes to raise the industrial plants production’s speed, without loosing the quality of the chicken meat. The province of Entre Ríos is the main producer of chicken meat at a national level.
In the province of Cordoba there are around 200 species of nocturnal butterflies, mostly little ones. Although they are mostly widespread between southern spring and autumn, during last summer’s months the capital city had an unusual increase of these insects. Specialists of the UNC explain the causes of the phenomenon.
A data base which will store information about natural environments of the North of the country has been created. It will be based on researches and scientific studies about biodiversity in the zone of Argentine Chaco. The software contains a lot of information about nature and numerous tools which permit to access reports and draw maps of biodiversity variables.
Ovine shepherding lead to the reduction of the vegetation and the replacement of native species by xerophytic plants which have more chemical and physical defense to face sheep. This was demonstrated by a group of researchers from Chubut which put collars with GPS to sheep in order to know their route by satellite images, among other working methods. It was determined that the disappearance of soft grass and its replacement by hard grass as a consequence of the shepherding habits make the ecosystem dryer.
In the province of Santa Fe some teachers are working on the design, normalization and production of portable maps for blind people to be able to get around in a safe and independent way.
