Tropical trees in the Andes are moving up -- toward extinction
An international study led by University of Miami tropical biologists reveals that tropical trees are migrating upslope to escape climate change, but not fast enough. |

The crisis of trust in Spanish political parties has transformed the political scene. 19.2% of Spaniards surveyed for the poll made by the Center for Sociological Research assure that political parties and politics in general represent one of the main problems that exist in Spain. In this context of distrust, transparency and promotion of citizen participation can transform political parties into more open institutions. |
The historically over-exploited Giant South American Turtle is making a significant comeback on river beaches in the Brazilian Amazon thanks to local protection efforts, say researchers at the University of East Anglia. |
In the Andean forests along the border of Chile and Argentina, there have long been speculations that the mouse-sized marsupial monito del monte (Dromiciops gliroides) climbs to lofty heights in the trees. Yet, due to the lack of knowledge about the region's biodiversity in the forest canopies, no previous records exist documenting such arboreal habits for this creature. |
Baby birds learn to fly. Baby mammals switch from milk to solid food. Baby bats, as winged mammals, do both at the same time during their transition from infants to flying juveniles. According to a new report from researchers STRI who studied Peters’ tent-making bats ('Uroderma bilobatum'), mothers prod their young with their forearms, perhaps encouraging them to fledge and wean. |
A billion light-years from Earth lies one of the Universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies known as Abell 2597. At the core of the central galaxy, a supermassive black hole is powering the cosmic equivalent of a monumental fountain, drawing in vast stores of cold molecular gas and spraying them back out again in an ongoing cycle. |
Crops such as wheat and maize have undergone a breeding process lasting thousands of years, in the course of which mankind has gradually modified the properties of the wild plants in order to adapt them to his needs. One motive was, and still is, higher yields. One "side effect" of this breeding has been a reduction in genetic diversity and the loss of useful properties. This is shown, among others, by an increased susceptibility to diseases, a lack of taste or a reduced vitamin and nutrient content in modern varieties. Now, for the first time, researchers from Brazil, the USA and Germany have created a new crop from a wild plant within a single generation using CRISPR-Cas9, a modern genome editing process. Starting with a "wild tomato" they have, at the same time, introduced a variety of crop features without losing the valuable genetic properties of the wild plant. The results have been published in the current issue of Nature Biotechnology. |
People with fewer resources contribute more to actions against climate change. This is the main result of a research that, by making a civic science experiment, suggests to act collectively fighting the climate change. The study, in which it has been measured how a group of people acts against a common harm, has shown that people are more or less likely to contribute money to fighting climate change depending on how wealthy they are. These are the principal findings of a research published in the journal PLOS ONE by researchers from the Universitat Rovira i Virgili, the University of Barcelona, the University of Zaragoza and the Carlos III University of Madrid. |
Argentine and Spanish paleontologists found an adult specimen and two juvenile specimens of this new species of dinosaur, which they named Lavocatisaurus agrioensis. They made an almost complete reconstruction of his skull and skeleton. |
As the sun set over the cloud forest in western Panama, Lynette Strickland still hadn’t found what she was looking for. Strickland spent all day exploring Fortuna, a mountainous area spanning the Continental Divide near the border of Panama and Costa Rica, in search of a glimmering golden beetle. But each time she flipped over a leaf or asked Smithsonian beetle expert Don Windsor ‘Is that it?’ the answer was ‘No'. |
Ancient populations in the Andes of Peru adapted to their high-altitude environment and the introduction of agriculture in ways distinct from other global populations that faced similar circumstances, according to findings presented at the American Society of Human Genetics (ASHG) 2018 Annual Meeting in San Diego, Calif. |
Researchers from diverse institutions, including School of Land Surveying, Geodesy and Mapping Engineering from Universidad Politécnica de Madrid, have developed a new methodology to create easy-to-understand maps for decision-making support after large earthquakes. |
The Theoretical and Computational Chemistry Group of the Universitat Jaume I, led by the professor of Physical Chemistry Juan Andrés Bort, has participated in an international research project for the development of electronic sensors that prevent carbon monoxide, naturalgas and bottled gas poisoning. The work has served as a basis for a bill in Argentina to establish the obligatory nature of installing toxic and explosive gas sensors that have a gas cutting mechanism in public spaces. |
Even after 40 years of recovery, secondary forests remain species and carbon-poor compared to undisturbed primary forests, a new study reveals. However these secondary forests - forests regrowing in previously deforested areas - are still vitally important to biodiversity conservation and carbon storage, argue scientists. |
The Internet has become a commercialized and centralized space, which is controlled by a small number of international companies. Corporations such as Google, Apple, Facebook, and Amazon extract personal information from the multitude of Internet users who visit their online services. They also decide the advertisements that are published and the place where the relevant information appears within their pages and search engines. |
Researchers at the University of York have identified genes in a parasite that could help clinicians predict drug treatment outcomes for patients with visceral leishmaniasis in Brazil. The findings could lead to a new prognostic test that can predict which patients will respond well to drug treatment and which patients need alternative solutions. |
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers found evidence that a white dwarf(the elderly remains of a star like the Sun) and a brown dwarf(a failed star without the mass to sustain nuclear fusion) collided in a short-lived blaze of glory that was witnessed on Earth in 1670 asNovasub Capite Cygni (a New Star below the Head of the Swan), which is now known as CK Vulpeculae. |
Secondary forests, or forests that have regrown after agriculture use, only last an average of 20 years, according to a recently released scientific paper. |
New research suggests that protecting the Amazon rainforest from deforestation may just be shifting the damage to a less renowned neighbor. The unintended consequences are profound. |
Treating dogs at a community level with systemic insecticide could considerably reduce the transmission of visceral leishmaniasis in Brazil, according to a modelling study led by ISGlobal, an institution supported by "la Caixa" Foundation. The results, published in PLOS Neglected Tropical Diseases, will help define which kind of insecticide is needed and how to apply it to achieve maximum effectiveness. |
