A newly developed wireless biologging network (WBN) enables high-resolution tracking of small animals, according to a study published April 2 in the open-access journal PLOS Biology by Simon Ripperger of the Leibniz Institute for Evolution and Biodiversity Science, and colleagues. As noted by the authors, WBNs could close an important gap in biologging: the fully automated tracking and proximity-sensing of small animals, even in closed habitats, at high spatial and temporal resolution. |

A team of Spanish researchers have designed and validated a simulator to enable study of the evolution of the COVID-19 illness in Spain and in all Europe, based on parameters such as climate, social distancing policies and transportation. This research work has been carried out by scientists and technologists from Universidad Carlos III de Madrid (UC3M), the Centro Nacional de Epidemiología (CNE) and the Consorcio Centro de Investigación Biomédica en Red (CIBER) from the Instituto de Salud Carlos III (ISCIII), in conjunction with the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS). |

In order to properly manage the Covid-19 pandemic, governments and the scientists who advise them need the most accurate data possible on the situation. The problem is that such data do not exist. The only data they have are those provided by laboratory tests. In other words, governments know how many people have tested positive, how many are in hospitals and how many are being treated over the phone. But by now it is more than evident that these are not the real data of the pandemic. Scientists around the world are now devising formulas to estimate figures that are more realistic. An international team led by researcher Antonio Fernández Anta of the IMDEA Networks institute is one of them. |

The formula "based on true events" and similar ones are used in audiovisual fiction, among other things, to short-circuit the critical and interpretative distance with the story being told, to generate a false sense of discursive transparency and to create simulations of factuality in the rhetorical and stereotyped space of an audiovisual discourse that hides its political dimension by appealing to "facts". These are the conclusions of a study carried out by a researcher from the Universidad Carlos III de Madrid (UC3M) that analyses the political dimension of this kind of expression used massively in TV series and fiction films. |

There is no longer a need to guess what ocean temperatures were like in the remote tropical Pacific hundreds of years ago. The ancient coral that lived there know all. A study in Science led by Rice University and Georgia Tech researchers parses the record archived by ancient tropical Pacific coral over the past millennium. That record could help scientists refine their models of how changing conditions in the Pacific, particularly from volcanic eruptions, influence the occurrence of El Niño events, which are major drivers of global climate. |

The complete isolation of the population in the face of an epidemic such as COVID-19 is a strategy that requires subsequently adopting active measures in order to maximise its effectiveness, such as conducting large scale diagnostic tests, isolating people with symptoms and identifying those with whom they have had contact. This is one of the main conclusions from a study conducted by a team of researchers from the Universidad Carlos III de Madrid (UC3M), the University of Zaragoza, the Massachusetts Institute of Technology (MIT) and the ISI Foundation in Italy. |

When cocaine kingpin Pablo Escobar was shot dead in 1993, the four hippos he brought to his private zoo in Colombia were left behind in a pond on his ranch. Since then, their numbers have grown to an estimated 80-100, and the giant herbivores have made their way into the country's rivers. Scientists and the public alike have viewed Escobar's hippos as invasive pests that by no rights should run wild on the South American continent. |

In the kelp forests of Tierra del Fuego, at the southernmost tip of South America, the relative abundance of kelp, sea urchins, and sea stars has not changed significantly since 1973. Alan Friedlander of the National Geographic Society's Pristine Seas project and colleagues present these findings in the open-access journal PLOS ONE on March 11, 2020. |

The ability of the world's tropical forests to remove carbon from the atmosphere is decreasing, according to a study tracking 300,000 trees over 30 years, published today in Nature. The global scientific collaboration, led by the University of Leeds, reveals that a feared switch of the world's undisturbed tropical forests from a carbon sink to a carbon source has begun. |

Lithium-ion batteries are used around the world and though over the last few years they have had some competition, such as sodium and magnesium, they continue to be indispensable due to their high density and capacity. The issue is this: this metal has major availability and concentration problems. Almost 85% of its reserves are located in what is known as the Lithium Triangle, a geographical area found on the borders of Argentina, Bolivia and Chile. In addition, it seems that demand will rocket over the next few decades because of the implementation of electric vehicles. Each car equals about 7.000 cell phone batteries, so reusing their different components has become an issue of utmost importance. |

With 5 trillion pieces of plastic in the oceans, the dynamics of marine environments are shifting in ways that are yet to be discovered. Over time discarded plastics, such as sandwich bags and flip-flops, have degraded into small particles, called microplastics, which are less than 5 mm long. Kassandra Dudek, a former Smithsonian Tropical Research Institute (STRI) fellow and doctoral student at Arizona State University, looked at how marine microbial communities colonize microplastics in Panama. |

Did a powerful queen of Cobá, one of the greatest cities of the ancient Maya world, build the longest Maya road to invade a smaller, isolated neighbor and gain a foothold against the emerging Chichén Itzá empire? The question has long intrigued Traci Ardren, archaeologist and University of Miami professor of anthropology. Now, she and fellow scholars may be a step closer to an answer, after conducting the first lidar study of the 100-kilometer stone highway that connected the ancient cities of Cobá and Yaxuná on the Yucatan Peninsula 13 centuries ago. |

A study carried out by researchers from the Universidad Carlos III de Madrid (UC3M) analyses the efficiency of the Spanish system of economically compensating the victims of sexual violence. This work has been undertaken within the framework of FAIRCOM, a European project coordinated by the UC3M. |

The Cuatro Cienegas Basin, located in Chihuahuan Desert in Mexico, was once a shallow sea that became isolated from the Gulf of Mexico around 43 million years ago. This basin has an unusual characteristic of being particularly nutrient-poor and harboring a 'lost world' of many below-ground and above-ground aquatic microbes of ancient marine ancestry. |

Data and the economy stemming from them are the engine for the fourth industrial revolution. However, and according to Nikolaos Laoutaris, there is a very important leading player who currently receives absolutely nothing of the huge profits generated by the activity: the people who provide these data. Only in a very few cases do the humans producing data receive a measly compensation in kind for it: free online services. |

Using ESO's Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star's surface show not only the fading red supergiant but also how its apparent shape is changing. |

The new species, named as Tralkasaurus cuyi, is much smaller than the carnivorous dinosaurs from the abelisaurus theropods group known until now. It measured about four meters and it was found at the northwest of Río Negro province. |

Tropical forests are allies in the fight against climate change. Growing trees absorb carbon emissions and store them as woody biomass. As a result, reforestation of land once cleared for logging, mining, and agriculture is seen as a powerful tool for locking up large amounts of carbon emissions throughout the South American tropics. |
