What animal bones tell us about the rise and fall of the Maya in Guatemala

Tens of thousands of tiny bone fragments reveal eating habits, ceremonial practices and the development of animal domestication during more than 2000 years of history

More than 35,000 bone and shell fragments from a Maya settlement in Ceibal, Guatemala tell the tale of animal use through the ups and downs of a great civilization according to a new report in the journal PLOS One by Ashley Sharpe, staff archaeologist at the Smithsonian Tropical Research Institute, with colleagues from the University of Arizona, the University of Ibaraki, Japan and Guatemala’s Institute of Anthropology and History and Universidad de San Carlos.

ALMA spots twinkling heart of Milky Way

Astronomers presume that a supermassive black hole with a mass of 4 million suns is located at the center of Sgr A*

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team interpreted these blinks to be due to the rotation of radio spots circling the supermassive black hole with an orbit radius smaller than that of Mercury. This is an interesting clue to investigate space-time with extreme gravity.

Platelets exacerbate immune response

Clotting cells are also an important regulator of inflammation, reveals study

Platelets not only play a key role in blood clotting, but can also significantly intensify inflammatory processes. This is shown by a new study carried out by scientists from the University of Bonn together with colleagues from Sao Paulo (Brazil). In the medium term, the results could open up new ways to treat autoimmune diseases. They have now been published in the renowned journal Cell Reports.

Demographic expansion of several Amazonian archaeological cultures by computer simulation

The study uses simulation techniques and shows that some cultural expansions from Amazonia during the late Holocene may have arisen from similar demographic processes to the Neolithic in Eurasia

Expansions by groups of humans were common during prehistoric times, after the adoption of agriculture. Among other factors, this is due to population growth of farmers which was greater than of that hunter-gatherers. We can find one example of this during the Neolithic period, when farming was introduced to Europe by migrations from the Middle East.

ESO instrument finds closest black hole to Earth

Invisible object has two companion stars visible to the naked eye

A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth. The black hole is closer to our Solar System than any other found to date and forms part of a triple system that can be seen with the naked eye. The team found evidence for the invisible object by tracking its two companion stars using the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile. They say this system could just be the tip of the iceberg, as many more similar black holes could be found in the future.

White-faced capuchin monkeys come down from the trees on Panama's Coiba Island

A group of intrepid biologists was surprised to find that capuchin monkeys spent so much time on the ground there

Crossing a 23-kilometer stretch of ocean from mainland Panama to Coiba, the largest offshore island in the Eastern Pacific, a group of intrepid biologists hoped to find species never reported there before. But in addition to discovering new species, the 2015 Coiba BioBlitz crew was surprised to find that capuchin monkeys spent so much time on the ground there.

How to get the most out of the tests

Article written by Ander Galisteo, predoctoral researcher at the IMDEA Networks Institute and the University Carlos III of Madrid (UC3M)

With Covid-19 hitting all areas of our lives, there is a need both socially and politically to know what the state of the citizenry is. We need to know how Covid-19 is evolving, how many citizens have it, how and where they are infected, what is the probability of them getting sick, etc. All these data are necessary in order to take appropriate measures and to know when and how we are going to recover certain areas of our lives and what other aspects are going to change forever.

Examining heart extractions in ancient Mesoamerica

New findings on procedures and meanings of human heart sacrifices in Mesoamerica

Sacrificial rituals featuring human heart extraction were a prevalent religious practice throughout ancient Mesoamerican societies. Intended as a means of appeasing and honoring certain deities, sacrifices served as acts of power and intimidation as well as demonstrations of devotion and gratitude. Human sacrifices were highly structured, complex rituals performed by elite members of society, and the ceremonies included a myriad of procedures imbued with symbolic significance.

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.

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.
