Learning to look after water

Researchers of the Conicet participate in a project with schools to control water quality of rivers and streams in the province of Tucumán

Water is tasteless, colourless and odourless; and it is more than two hydrogen atoms bonded to one oxygen: it is essential for the development of life. Although it covers more than 70% of the land surface, only 1% of the fresh water is available because the rest is mainly in the sea and the poles. Thus, water is a very scarce resource so it must be looked after and used rationality.

The digital showcase of radio

A project of the Universidad Pontificia de Salamanca aims to make programme planning information and access to the broadcasts of all Spanish radios available to all listeners in a single Internet application

First day of class at the Faculty of Communication Studies. The lecturer is talking about "the dial" of the radio. The what? Some of the young people are not familiar with the term. They have probably never tried to tune in to a radio station on a traditional radio with its dial and numbers indicating the various frequencies on the Medium Wave (MW) or Frequency Modulation (FM) band. They belong to a generation that has grown up with digital media and with mobile phones that give access to almost all contents. The anecdote dates from the beginning of this academic year and reveals a new situation to which not all traditional means of communication are adapting in the same way.

Valladolid researchers help to shed light on the origin of Indo-European languages

A study published in the Nature magazine reveals that 4,500 years ago there was a massive migration of peoples from the Russian steppes to Central Europe, which favoured the expansion of Indo-European languages

Reseachers of the Prehistory and Archaeology Department of the Universidad de Valladolid (UVA) were part of the international scientific team that has shed light on the origin and expansion of Indo-European languages. In order to achieve this the most wide-ranging research work involving ancient DNA to date has been carried out, to be precise of 69 individuals who lived in Europe between 3,000 and 8,000 years ago.

Long-term tropical lizard decline linked to El Niño events

Natural ups and downs in the numbers of a tropical lizard species may be a result of global-scale El Niño events, according to a unique 40-year census conducted at the Smithsonian Tropical Research Institute in Panama

Natural ups and downs in the numbers of a tropical lizard species may be a result of global-scale El Niño events, according to a unique 40-year census conducted at the Smithsonian Tropical Research Institute in Panama. The estimated number of lizards on Barro Colorado Island has declined dramatically: In the last decade, census takers recorded only about 35 percent of the number of lizards, Anolis apletophallus, present during 1970-1980.

Progress in the study of the mitochondrial changes that occur with cancer

Researchers of the MitoXT Laboratory of the Neuroscience and Cell Biology Centre of the University of Coimbra are studying in depth how these changes may act as a therapeutic objective

Mitochondria are organelles that play an essential role in the cell. As well as being responsible for cellular respiration, they regulate death, the signalling of calcium, the synthesis of steroids, redox homeostasis (the reduction-oxidation reaction), and cell ions. Researchers of the MitoXT (Mitochondrial Toxicology and Experimental Therapeutics) Laboratory of the Neuroscience and Cell Biology Centre of the University of Coimbra in Portugal are working essentially on assessing mitochondrial changes in cancer.

Conicet researchers contribute to the knowledge on the regulation mechanisms of genes in eukaryotic organisms

In the future, these findings may be applied in agricultural and health issues to provide for creative solutions

Marcelo Yanovsky, researcher of the Conicet at the Instituto de Investigaciones Bioquímicas de Buenos Aires (IIBBA, CONICET-IIBFL) [Institute of Biochemical Research of Buenos Aires] and his lab team proved that LSM genes, which are present in all eukaryotic organisms ranging from yeast to humans, are controlled by a biological clock. Experts affirm that faults in its function alter circadian rhythms not only in the plant world but also in in vitro culture human cells.

Smithsonian scientists explain spread of chikungunya vector tropical disease

Chikungunya causes fever, fatigue and joint swelling and is transmitted by the Asian tiger mosquito, ‘Aedes albopictus’

The tropical disease chikungunya began twisting Western tongues last July when the first locally transmitted case was reported in Florida. Spotted in the Caribbean in 2013, the disease spread explosively throughout the Americas last year. Chikungunya’s arrival in Panama prompted Smithsonian Tropical Research Institute (STRI) scientists to examine how human activity spreads its mosquito vector and the serious implications this has for disease ecology everywhere.

Argentine and german scientists found how a protein regulates the growth of some type of tumours

This finding would be used to develop localized therapies

In 2007, the team coordinated by Eduardo Arzt, CONICET senior researcher and professor at the Faculty of Exact and Natural Sciences of the University of Buenos Aires, identified for the first time the genetic code for RSUME protein and discovered that one of the roles of this molecule is to modify proteins to assign new roles, for instance the ability to mediate the cell’s response to external factors such as lack of oxygen, etc.
