¿Why can hot water freeze faster than cold water?

Spanish researchers have discovered this effect in granular media, opening the door to the theoretical understanding of the Mpemba effect

A team of researchers from Universidad Carlos III de Madrid, the Universidad de Extremadura and the Universidad de Sevilla have defined a theoretical framework that could explain the Mpemba effect, a counterintuitive physical phenomenon revealed when hot water freezes faster than cold water.

Duo of titanic galaxies captured in extreme starbursting merger

The ADFS-27 galaxy pair is located approximately 12.7 billion light-years from Earth in the direction of the Dorado constellation

New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) have uncovered the never-before-seen close encounter between two astoundingly bright and spectacularly massive galaxies in the early Universe. These so-called hyper-luminous starburst galaxies are exceedingly rare at this epoch of cosmic history — near the time when galaxies first formed — and may represent one of the most-extreme examples of violent star formation ever observed.

Stop using antibiotics in healthy animals to prevent the spread of antibiotic resistance

A systematic review published today in 'The Lancet Planetary Health' found that interventions that restrict antibiotic use in food-producing animals reduced antibiotic-resistant bacteria in these animals by up to 39%

WHO is recommending that farmers and the food industry stop using antibiotics routinely to promote growth and prevent disease in healthy animals. The new WHO recommendations aim to help preserve the effectiveness of antibiotics that are important for human medicine by reducing their unnecessary use in animals. In some countries, approximately 80% of total consumption of medically important antibiotics is in the animal sector, largely for growth promotion in healthy animals.

Untangling the family tree of the main groups of dinosaurs

The result was published in Nature in response to the March publication in which the English researchers had proposed a radical change in the family tree of the lineage of those prehistorical animals

In March 2017, a research team led by Matthew Baron of the University of Cambridge published a study in Nature. The scientists had proposed a radical revision on the understanding of the early evolution of dinosaurs and the family tree relationship among them. They suggested that the traditional classification between Ornithischia –bird hipped- and Saurischia – lizard hipped-, was modified.

ALMA discovers cold dust around nearest star

These structures are similar to the much larger belts in the Solar System and are also expected to be made from particles of rock and ice that failed to form planets

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the Sun. The data also hint at the presence of an even cooler outer dust belt and may indicate the presence of an elaborate planetary system. These structures are similar to the much larger belts in the Solar System and are also expected to be made from particles of rock and ice that failed to form planets.

The Neanderthals’ last breath

Argentine researchers managed to digitally reconstruct the nasal airflow in Neanderthals and simulate the respiratory cycle under different climatic scenarios

Heavy frosts and severe climates are extreme conditions. How did humans manage to survive the last glaciation? Breathing is the answer. Although this seems to be obvious, a study published in PNAS (Proceedings of the National Academy of Sciences) claims that the internal nasal cavity of humans and Neanderthals –species that occupied extreme cold and dry landscapes– allowed them to warm and moisten the inhaled air. These results are vital to understand how our human lineage managed to resist severe climate conditions during their dispersion through Eurasia at the end of the Pleistocene epoch.

Research identifies potential targets for treatment of leishmaniasis

Brazilian scientists show that parasite's penetration of host cells increases expression of certain microRNAs capable of inhibiting action of immune system.

Researchers at the Bioscience Institute of the University of São Paulo (IB-USP), in Brazil, are starting to unravel the molecular mechanisms by which the parasite that causes cutaneous leishmaniasis manages to circumvent the host organism’s defenses and infect new cells.

Recent connection between north and south america reaffirmed

Aaron O’Dea, staff scientist at the Smithsonian Tropical Research Institute (STRI), and colleagues writing in 'Science Advances' firmly set the date at 2.8 million years ago

Long ago, one great ocean flowed between North and South America. When the narrow Isthmus of Panama joined the continents about 3 million years ago, it also separated the Atlantic from the Pacific Ocean. If this took place millions of years earlier, as recently asserted by some, the implications for both land and sea life would be revolutionary. Aaron O’Dea, staff scientist at the Smithsonian Tropical Research Institute (STRI), and colleagues writing in Science Advances firmly set the date at 2.8 million years ago.

Neanderthal child tooth and parietal fragment discovered at Teixoneres Cave (Barcelona, Spain)

Ruth Blasco, researcher at the CENIEH, is co-leader of the excavation project "Teixoneres Cave", one of the Middle Palaeolithic sites in the Iberian Peninsula with new Neanderthal fossils

It is not common to find human remains in a Pleistocene archaeological site; nevertheless, they are very significant and can be used in numerous research fields. The analysis of the characters of each fossil gives us valuable information in order to understand not only the variability of a species, but also its diet type or its development patterns.

After the Age of Dinosaurs Came the Age of Ant Farmers

A group of South American ants has farmed fungi since shortly after the dinosaurs died out, according to an international research team including Smithsonian scientists

A group of South American ants has farmed fungi since shortly after the dinosaurs died out, according to an international research team including Smithsonian scientists. The genes of the ant farmers and their fungal crops reveal a surprisingly ancient history of mutual adaptations. This evolutionary give-and-take has led to some species—the leafcutter ants—developing industrial-scale farming that surpasses human agriculture in its efficiency.
