What is responsible or sustainable tourism



Sustainable tourism is one that is committed to having a low impact on the environment and local culture. According to the World Tourism Organization, it is defined as "that fully takes into account the current and future economic, social and environmental impacts to meet the needs of visitors, the industry, the environment and the host communities."

For some years, an accrediting body linked to UNESCO and called the Global Council of Sustainable Tourism has awarded the "Biosphere World Class Destination" certificate, which recognizes companies, destinations, products and tourist establishments that have made sustainable tourism the central axis of Your activities. Barcelona was the first urban destination in the world to obtain this certification in 2011.

In Europe, according to a recent report from Voyageprive.com, Spain offers 50% of the offer of all the ecological tourist destinations of the continent.

Do the plants recycle?



The answer is yes. How do they do that? The recycling process of plants is called endocytosis and is based on the movement of molecules into the cell. Now, thanks to a team of scientists led by the Institute VIB (The Flanders Institute for Biotechnology), the University of Ghent (Belgium), and the Max Planck Institute (Germany) has managed to identify a new complex of adapter proteins, essential in this process and found only in the plants. The results of the study have been published in the journal Cell.

The new complex, called TPLATE, is part of a small number of adapter proteins that confirms a great discovery in evolutionary terms, since research focused on the endocytosis of plants, animals and yeast has been carried out for decades and it is the first time In the history we discover a protein complex that exists exclusively in plants.

The complex is made up of the TPLATE protein and seven other proteins not described so far. This protein complex has proved to be essential for plant endocytosis since it is the first to reach the area of ​​the membrane where endocytosis must begin, since the cell has to constantly adjust the lipid and protein composition of its membrane; and, for this, old proteins are eliminated or recycled when new proteins are incorporated in the process.

Videogames to learn history, economics and environment



Current video games not only entertain. Some such as Age of Empires, Caesar and even Sim City have become effective information and training tools, as confirmed by researchers at the University of Huelva (UHU) in an article published in the magazine Computers & Education.

According to the experts of the UHU, videogames have a proven utility for the teaching of Social Sciences. His research project, directed by José María Cuenca López and Miriam Martín Cáceres, had as fundamental axis the analysis of 35 programs with different themes (Politics, Geography and History ...) among more than 400 Primary and Secondary School students from centers of Huelva

Experts believe that new technologies have led to the emergence of dynamic games with different levels of interaction, in which huge amounts of data, information, procedures and values ​​are intimately linked. "We have been able to appreciate not only an improvement in the teaching process, but a better predisposition of the student to access this information", underlines José María Cuenca. Cuenca López and Martín Cáceres divided the essay into several disciplines. To analyze the History, they used the Age of Empires video games and the Empire Earth. For Town Planning and Territory, they did the same with Caesar and Sim City. And the teachings related to Democracy and Citizen Participation, Economy and Business, and Environment were resolved with Sim City, Wall Street Trader and The Settlers, respectively.

Those that had greater acceptance were those of historical content - "by the spectacularity of the images and the dynamism of the development of the game" - and those related to the territory. However, he says, "it would be interesting to narrow the content filters to offer greater rigor over what is published."

"Video games have become laboratories for social experiments, especially because they reproduce scenarios, conditions and situations that affect a specific human phenomenon," he says. In this way, the researcher intends to break a spear in favor of "good use" of this technology, both in classrooms and in homes. "It requires, on the other hand, efforts of the teachers, it is a complementary technique," he says.

Plocan, a boost to the Blue Economy

The objective of the future multifunctional ocean complexes will be to promote and optimize the management of maritime space in coherence with the Blue Economy concept promoted by the European Commission.





Oceanic Platform of the Canary Islands (PLOCAN) is a marine research and technology laboratory funded by the EU, the Spanish Government and the Government of the Canary Islands. Installed 1.5 kilometers from the northeast coast of the island of Gran Canaria, it welcomes teams of scientists working in fields such as biotechnology, renewable energy, and in the study and observation of the ocean.

This initiative contributes to the Blue Economy promoted by the European Commission, which seeks to create employment and wealth in the marine and maritime sectors, in a way that respects the environment. Thus, the research and technologies developed in PLOCAN will eventually reach society in the form of sustainable products and businesses.


One of the new initiatives of PLOCAN is the REDSUB project, an electrical network to support experimentation and testing of new technologies that use marine energy resources to generate electricity and connect technologies for observation at increasing depths. The system consists of predominantly submarine wiring capable of transporting energy to earth up to 15 MW.





TROPOS, the ocean of tomorrow

PLOCAN has led the TROPOS project, co-financed by the European Commission and developed over 36 months in three regions: a tropical one, Taiwan; a subtropical, Canary Islands; and a Mediterranean, Crete.

This initiative has consisted of the design of a multifunctional oceanic complex that integrates the exploitation of oceanic energy resources -especially the wind-, aquaculture, maritime transport related to both sectors and leisure, in three regions.

The TROPOS project was chosen by the European Commission within the framework of The Ocean of Tomorrow program, which proposes "joining research efforts to face the challenges of ocean management" through the development of multifunctional complexes.

TROPOS aims to optimize the use of maritime space, in anticipation of the perspective of global population growth and the current limitation of land space in coastal areas and their subsequent degradation. The program had a financing of 14 million euros, of which 4.9 were for TROPOS.

The objective of these future multifunctional ocean complexes would be to combine different sectors of activity to promote and optimize maritime space management in coherence with the Blue Economy concept promoted by the European Commission.

The complexes would be adapted to deep waters and would allow the exploitation of the oceanic resources and their interrelation with the economy and the environment. TROPOS, promoted by PLOCAN, in addition to energy, aquaculture and transport, introduced leisure as a differentiating element, proposing recreational activities (floating restaurants, sailing, diving ...) and observation of cetaceans and birds.
