ESO telescope sees star dance around supermassive black hole, proves Einstein right

A star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity

Observations made with ESO's Very Large Telescope (VLT) have revealed for the first time that a star orbiting the supermassive black hole at the centre of the Milky Way moves just as predicted by Einstein's general theory of relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. This long-sought-after result was made possible by increasingly precise measurements over nearly 30 years, which have enabled scientists to unlock the mysteries of the behemoth lurking at the heart of our galaxy.

Bocas dolphins may be more sociable while we shelter in place

A study of dolphin behavior in the presence of tourist boats informs conservation efforts

Wild animals are changing their behavior as the coronavirus puts the world in lockdown: pumas stroll the streets of Boulder, Colorado and dolphins frolic along the beaches of Lima, Peru, replacing the usual bobbing crowd of surfers. At the Smithsonian Tropical Research Institute’s Bocas del Toro Research Station in Panama, researchers are sharing new results about dolphin behavior with and without tourist boats, giving us some clues about how dolphins may be experiencing the world as humans shelter in place.

Event Horizon Telescope Images of a Black-Hole Powered Jet

The collaboration has extracted new information from the EHT data on the distant quasar 3C 279

Something is Lurking in the Heart of Quasar 3C 279. One year ago, the Event Horizon Telescope (EHT) Collaboration published the first image of a black hole in the nearby radio galaxy M 87. Now the collaboration has extracted new information from the EHT data on the distant quasar 3C 279: they observed the finest detail ever seen in a jet produced by a supermassive black hole. New analyses, led by Jae-Young Kim from the Max Planck Institute for Radio Astronomy in Bonn, enabled the collaboration to trace the jet back to its launch point, close to where violently variable radiation from across the electromagnetic spectrum arises.

Amazonian crops domesticated 10,000 years ago

Earliest humans in the Amazon created thousands of 'forest islands' as they tamed wild plants

The earliest human inhabitants of the Amazon created thousands of artificial forest islands as they tamed wild plants to grow food, a new study shows. The discovery of the mounds is the latest evidence to show the extensive impact people had on the area. From their arrival 10,000 years ago they transformed the landscape when they began cultivating manioc and squash.

An international team counts more than two million current symptomatic cases of Covid-19 in Spain

Researcher Antonio Fernández Anta has launched a study to estimate the actual incidence of the pandemic in eleven countries

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.

A research looks at the effects of the "based on true events" formula

This formula is 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

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.

Coral tells own tale about El Niño's past

Rice, Georgia Tech study in Science reveals Pacific temperatures over a millennium

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 effectiveness of social distancing strategies in the face of an epidemic has been analysed

An international study based on census and real-world mobility flow

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.

Pablo Escobar's hippos may help counteract a legacy of extinctions

Study from international team of researchers including UMass Amherst biologist John Rowan shows introduced species can restore a lost world

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.

New lithium batteries from used cell phones

A research project at the University of Cordoba (Spain) and San Luis University (Argentina) was able to manufacture new lithium batteries from used cell phones, devices with a low recycling rate

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.
