It is apparently many-sided, restless within the vegetal cell and it is possible to see it with avant-garde microscopes. It is a protein called ASR, which provides resistance to drought. Its efficiency was already proved by being introduced in plants like corn and rice. According to the researchers, this “star” protein emerges when the plant is in extreme drought and threatens its survival.
The biologist Julián Lescano waits for summer rains to go to the lakes to study the species of amphibians which live in them. In the nights after the rain, the species adults are reproduced and they do it singing. Lescano can, then, watch them or recognize them for their singing and know what species it is. His research remarks that, due to environmental deterioration, in some lakes where there should be ten species of amphibians, there are currently three.
It is a unique experience at world level; researchers developed a biotechnological treatment for sewage effluents which permits to increase biomass and purify water. The project seeks to generate lactic acid, which is the main material in the production of biodegradable plastics, which might turn Rosario in the first seat of a biomass factory.
Bees, beetles, flies, butterflies, birds and bats are fundamental in the development of crops and regional economies as they offer a way for sustainable agriculture. This was proved by an investigation carried out in 19 countries, where they reached the conclusion that heterogeneity in crops and the use of pollinators provide considerable economic yields.
Dr. Sandra J. Bucci is part of an international team of 24 scientists called by a German university with the aim of creating a global synthesis about the resistance to drought cavitations in plants belonging to wooded ecosystems, including bushes and savannahs around the world. The research was initiated at the end of 2009 and the results showed that most trees, even those in tropical rainforests, work very close to their hydraulic safety threshold, which leaves them vulnerable to extreme drought.
Researchers carry out alimentary audits about the food delivered by means of an assistance program in 36 schools in the city. Harmless food is that which doesn’t damage, as it doesn’t impose risks from the microbiological point of view. To achieve this quality, some parameters are controlled, such as cooking temperature and the level of protection of the people who serve the food.
Excessive speed or carelessness during driving a car cause accidents and Justice has to determine the responsibility of the parties in cases in which the accident caused the loss of human lives, serious health consequences or material damages. In order to do that, it resorts to experts in physical sciences which contribute data to reconstruct the moment of the accident and facilitate to the judges the determination of the responsibilities of the people involved.
A team formed by scientists from diverse academic national and foreign institutions concluded that America’s Colossus is 6,960.8 meters high above sea level. Before carrying out these measurements, the only antecedent registered was an investigation carried out by the University of Buenos Aires which dates from 1956. The results which revealed the height are the product of two years of GPS and gravity measurements.
The need to replace fossil fuels led a group of researchers to create a tool which can be applied to diverse plants to produce biofuels. The biotechnological tool is low cost and can be applied in vegetal species which do not compete with alimentary uses.
The GEM (Global Earthquake Model) started in 2009 with the objective of gathering world information about active faults and seismic sources. After years of work, its objectives were redefined privileging the study of the vulnerability of the most densely populated zones. “Great losses will occur, because these cities have grown without planning and because they have done it without seismic resistant buildings”, explained Carlos Costa, one of the researchers of the project.
A multidisciplinary team of researchers works to bring people closer to the chance of using umbilical cord stem cells in therapies. This kind of cells can only be obtained after birth and a reduced amount is extracted; that is why the creation in vitro of the conditions for their multiplication is one of the aspects dealt with by the researchers’ work.
The cadmium present in the soil might reach peanut crops and bring, in the long term, economic consequences which might affect the performance of the production of peanut crops as well as health problems, as they might cause diseases in people or animals which consume peanuts or their derivatives.
The BS Oscar Pérez de la Torre, specialist in Biological Sciences wrote the book “Lichens of the province of Chubut”, which won the first place of the competition of the Editorial Fund of Chubut in 2009 and is in edition stage. The book, where there are included images and information about the variety of plants of the autochthonous landscape, will be very useful for the different levels of the educational system.
River Nuevo is born in the prairie of the top of Cerro El Morro up to River V, extending in a wide zone of the province of San Luis. It is a group of various courses which grew a lot during the eighties. Now the basin is connected and presents a salty water continuous fluvial course. Researchers have studied its behavior, the water characteristics and the consequences this brought to the people and agricultures of the zone.
