Astronomers confirm the boom of star birth when galaxies merge, thanks to artificial intelligence

Published

on

A new study by an astronomer at the Dutch Space Research Institute, Lingyu Wang, confirmed the theory of star formation. This researcher actually analyzed more than 200,000 galaxies and confirmed that the process of galaxy fusion is one of the driving forces of the birth of a star, though not uncommon in itself.

The theory has formulated that, in practice, the fusion of galaxies causes a star phase that is at least twice as strong in terms of star formation, including the entire period of fusion. This phenomenon is explained by shock waves caused by the collision of interstellar gases that cause the birth of stars.

But the real novelty of this study is in the fact that researchers have used artificial intelligence software to analyze over 200,000 record numbers of galaxies. In fact, with such large databases, researchers had to rely on deep learning algorithms to improve the reproducibility of their research.

This method, as suggested by William Pearson, analyzes data where artificial intelligence provides a larger and more complete set of space telescopes.

Wang points out that not all processes are completely entrusted to the computer. However, a proper “training” phase is always required to provide good examples for the software.

Neanderthal’s were also skilled divers to collect bivalves and shells

Published

on

When we think of Neanderthals our thoughts usually go to hunter-gatherers but these hominids were most likely also skilled swimmers and were also able to dive underwater to collect seafood. This is the result of a study conducted by a team of researchers led by Paola Villa of the University of Colorado Boulder who analyzed several findings found in the Grotta dei Moscerini, a cave located near a beach in Lazio.

Already several decades ago archaeologists had collected several interesting artifacts and remains of animal planets, mostly shells, from this area but the team of researchers revealed new secrets in a new study that appeared on PLOS ONE. The Neanderthals not only collected shells and any edible marine animals that lay on the beach but also dived several meters to better meet their dietary needs.

These clues show that the Neanderthals actually had a much deeper relationship with the sea than previously thought, something that many paleoanthropologists did not pay much attention to. Villa, together with his colleagues, analyzed the tools that the Neanderthals used to work the shells in order to transform them into useful cutting tools.

Many of the shells found showed dull and slightly abraded exteriors, as if they had been polished over time, indicating that they had been taken from a sandy beach. However, several other shells, at least a quarter of the total, show that they were torn directly from their natural habitat at the bottom of the sea.

According to the researcher, the Neanderthals used to submerge to a depth of up to four meters to collect live seafood and bivalves, naturally without any diving equipment, which indicates a certain degree of skill, probably equal to that of Homo sapiens, at least as far as obtaining food from the deep water.

This study will help to change the idea of Neanderthals seen as hunters of large mammals.

Bizarre objects discovered around a black hole in the centre of the Milky Way

Published

on

A team of astronomers believes they have discovered a new class of cosmic objects after observing “bizarre objects” at the center of our galaxy, in the very region where there is a huge supermassive black hole called Sagittarius A.

It seems to be somewhere between a gas condensate and a star, as suggested by Andrea Ghez, professor of astrophysics and director of the Galactic Center Group at the University of California at Los Angeles. In the study, published in Nature, compact objects are described that at a certain point seem to stretch as they approach the black hole. The orbit of these objects is relatively long and can range from 100 to 1000 years, as explained by Anna Ciurlo, another UCLA researcher involved in the same study.

The objects, called G3, G4, G5 and G6, stand alongside two other objects (G1, discovered in 2005, and G2, discovered 2012) previously discovered that were very strange. All these objects, according to Ghez and colleagues, could be the result of the fusion of binary stars, i.e. stars that rotate around each other attracted by their gravity.

These pairs of stars, once they reach a point in their orbit very close to Sagittarius A*, seem to merge because of the immense gravitational force of this supermassive black hole, a process, the process of fusion, which takes more than a million years to complete.

According to the researchers, these objects, whose form and substance are apparently not understood, could really be the final product of fusion, a product arrived in a state of relative “calm.” However, we are talking about an extreme environment, the one around the black hole at the center of the Milky Way, which has a density of stars much higher than our galactic quarter, at least a billion times, according to what Ghez himself explains.

In a region like this, not only the gravitational attraction is very strong, but also the magnetic fields can be considered “extreme.” Precisely for this reason, we should not be so surprised if, in a region like this, we find something that, at least initially, we cannot explain its features or its oddities.

Blood vessels of women age before those of men

Published

on

Women’s blood vessels appear to age faster than men’s according to a new study conducted by researchers at the Smidt Heart Institute. Among other things, this study could explain why, with regard to different heart diseases, women heal at different times than men.

The study, published in JAMA Cardiology, shows in particular that the blood arteries, both the larger ones and the smaller ones, seem to age faster, which confirms a different physiology also with regard to the blood system of women than men. Researcher Susan Channing, senior author of the study, together with colleagues analyzed data from 145 blood pressure measurements collected over a period of 43 years from a total of 32,833 patients aged between 5 and 98 years, so a fairly large and diverse database.

Comparing the data of women with those of men, the researchers found that the evolution of the vascular function of females is “very different” from that of males. For example, women showed levels of increased blood pressure earlier in life than men. This means that if the same danger thresholds for hypertension are used for both males and females, a 30-year-old woman with hypertension is still at a higher risk of cardiovascular disease than a man of the same age and with the same level of hypertension.

These are concepts that should make us rethink the methods that are used today to treat the various heart diseases and in general make us rethink female cardiovascular health. Specifically, as Christine Albert, President of the Department of Cardiology at the aforementioned institute, explains, different aspects of today’s cardiovascular therapies must be adapted specifically for women.

Moreover, the results obtained from studies conducted on men cannot be applied directly to women.
