Scientists say that the results we have obtained can help to analyze the skeletons of different periods of Roman.

According to some historians, the skeletal remains of children found in ancient tombs in different areas of the UK, suggests that the Romans practiced infanticide. Recently, researchers have shown, however, that the bones belong to stillbirths identified and buried by their families in accordance with the customs of that time.

So far, Some argue that the Romans killed their children in an attempt to have more boys than girls. However, a team led by researchers from the Natural History Museum, Museum of London and Durham University have shown that infaticide was not a practice widespread in the Roman province of Britannia, and most of the remains of children found belonged to individuals born dead.

Distinguishing ,, stillbirths remains from those of children born alive is important for archaeologists to study the health of populations in the past and understand how they pertained to cases where children died, "says Dr. Thomas Booth, one of the study coordinators conducted by British experts.

In their research, experts analyzed the skeletons of 10 children buried in Roman cemeteries near London. With the help of the X-ray microtomografiei, researchers were able to study the material composition osteological and found that the biggest part of it was unaffected by bioeroziune process during which the bacteria in the intestines begin to cause bone deterioration immediately after the body dies. In this way, scientists have learned that the bones belonged to stillbirths.

,, The ability to differentiate stillbirths remains from those of children born alive, without affecting the skeletons analyzed, will have a profound impact on the study of past human life, "added Thomas Booth.

Now researchers hope that further studies will be done to improve the knowledge we have so far about how people lived in Britannia.


,, Now we can apply the results of this research to study the skeletons of different periods of Roman, to investigate the risks of death and find out how they are related to the changes undergone by London, "says Dr. Rebecca Redfern, another coordinator of the study.

What are the differences between dog lovers and cat lovers?

There was always a rivalry, manifested more or less, between those who love cats and those who declare themselves lovers of dogs.

Facebook has observed the behavior of the 160,000 US animal lovers with a desire to put an end to all these stereotypes.

Giant social media gathered "evidence" of users published on their page on the social networking site images of cats and dogs and found that 30% of those who were distributing photos of cats were alone, compared with a rate of only 24% for dog lovers write thought.

The study concentrated on the behavior of cat lovers and dog lovers to show who they are, how they live and how much they resemble their furry friends.

And even if the main results show that owners of cats are prone loneliness concerning love affairs, the myth of the so-called "cat-lady" - old maid who lives surrounded only by cats - was dismantled, and researchers say there sex or age limit for cat owners who are not involved in a relationship.

To be able to search through thousands of profiles and millions of photographs, Facebook has used an object recognition technology, the same technology used to help blind users. Then, the research team looked at the profiles was selected to understand better what they like those people, who are they and why marital status.

Dog lovers are on Facebook, on average, more than 26 friends cat lovers. They are also more extroverted, resembling their four-legged friends. Moreover, they are luckier regarding your love life more quickly able to establish connections both online and in real life.

Even if cat owners say they are tired all the time, the study shows that they are invited to more events than owners of puppies. However, cat lovers prefer friendships with other cat lovers. However, that does not mean they refuse to give a chance to those who prefer dogs.

When it comes to relaxation methods, the results turn out to be very different between the two groups. Cat lovers prefer activities such as watching a movie, TV watching TV or reading. They are passionate about everything that science fiction and animation. On the other hand, dogs lovers prefer love stories.

The study showed that between lovers puppies, were the favorite films like "Marley & Me" and "Rocky", while cat lovers preferred "Dracula" or "World War Z".

However such films as "The Great Gatsby," "Seinfeld" or "Frozen" was loved equally by the two camps.

Another interesting point is that dogs do not give lovers "check in" as much as cat lovers.

Do Black Holes have a back door?

One of the biggest problems when studying black holes is that the laws of physics as we know them cease to apply in their deepest regions. Large quantities of matter and energy concentrate in an infinitely small space, the gravitational singularity, where space-time curves towards infinity and all matter is destroyed. Or is it? A recent study by researchers at the Institute of of Corpuscular Physics (IFIC, CSIC-UV) in Valencia suggests that matter might in fact survive its foray into these space objects and come out the other side.

Published in the journal Classical and Quantum Gravity, the Valencian physicists propose considering the singularity as if it were an imperfection in the geometric structure of space-time. And by doing so they resolve the problem of the infinite, space-deforming gravitational pull.

"Black holes are a theoretical laboratory for trying out new ideas about gravity," says Gonzalo Olmo, a Ramón y Cajal grant researcher at the Universitat de València (University of Valencia, UV). Alongside Diego Rubiera, from the University of Lisbon, and Antonio Sánchez, PhD student also at the UV, Olmo's research sees him analysing black holes using theories besides general relativity (GR).

Specifically, in this work he has applied geometric structures similar to those of a crystal or graphene layer, not typically used to describe black holes, since these geometries better match what happens inside a black hole: "Just as crystals have imperfections in their microscopic structure, the central region of a black hole can be interpreted as an anomaly in space-time, which requires new geometric elements in order to be able to describe them more precisely. We explored all possible options, taking inspiration from facts observed in nature."

Using these new geometries, the researchers obtained a description of black holes whereby the centre point becomes a very small spherical surface. This surface is interpreted as the existence of a wormhole within the black hole. "Our theory naturally resolves several problems in the interpretation of electrically-charged black holes," Olmo explains. "In the first instance we resolve the problem of the singularity, since there is a door at the centre of the black hole, the wormhole, through which space and time can continue."

This study is based on one of the simplest known types of black hole, rotationless and electrically-charged. The wormhole predicted by the equations is smaller than an atomic nucleus, but gets bigger the bigger the charge stored in the black hole. So, a hypothetical traveller entering a black hole of this kind would be stretched to the extreme, or "spaghettified," and would be able to enter the wormhole. Upon exiting they would be compacted back to their normal size.

Seen from outside, these forces of stretching and compaction would seem infinite, but the traveller himself, living it first-hand, would experience only extremely intense, and not infinite, forces. It is unlikely that the star of Interstellar would survive a journey like this, but the model proposed by IFIC researchers posits that matter would not be lost inside the singularity, but rather would be expelled out the other side through the wormhole at its centre to another region of the universe.

Another problem that this interpretation resolves, according to Olmo, is the need to use exotic energy sources to generate wormholes. In Einstein's theory of gravity, these "doors" only appear in the presence of matter with unusual properties (a negative energy pressure or density), something which has never been observed. "In our theory, the wormhole appears out of ordinary matter and energy, such as an electric field" (Olmo).

The interest in wormholes for theoretical physics goes beyond generating tunnels or doors in spacetime to connect two points in the Universe. They would also help explain phenomena such as quantum entanglement or the nature of elementary particles. Thanks to this new interpretation, the existence of these objects could be closer to science than fiction.

Was Venus Once A Habitable World Like Earth?

Experts assume that traces habitable landforms would have disappeared after a few hundred million years.

Until now, attention to the search for a habitable planet was focused on Mars, since it is assumed that it had a structure similar to Earth. There are, however, argue that we should take into account other variables such as, for example, Venus.

In a study published in the journal Geophysical Research Letters, a team of American researchers simulated the appearance that supposedly had a Venus, recreating how its surface showed, but the amounts of sunlight that reached here. The experiment results have led scientists to conclude that the planet was habitable in 2.9 billion years ago and 715 million years before, because here there is a temperature and water surfaces similar to those on Terra.

However, no evidence was found so far to indicate the presence of water on the surface of Venus, as it happens, for example, in the case of Mars. Here, researchers have identified the fingerprints of former rivers and oceans and believe that such structures could be found on Venus, but they were reshaped during volcanic activity occurred ago over 700 million years.

Experts have assumed, since Venus there was a habitable environment, should not exclude the possibility that there existed forms of life: ,, Both planets have oceans where water might have come into contact with rocks and organic molecules, giving rise to chemical processes. From what we know so far, these are the conditions that make possible the emergence of life, "says David Grinspoon, one of the coordinators of the study conducted by the Planetary Science Institute in Arizona.

Although Venus was habitable for nearly 2 billion years, it is uncertain whether complex life forms could have developed during this period. In this regard, we are given the example of the Earth, where the development of complex organisms lasted about 3 billion years.

Even if the history of living on Venus could be considered, scientists say, however, that we need much more information to reach a conclusion in this regard

The Milky Way's Halo Spins With The Galaxy

Astronomers from the University of Michigan have, for the first time, measured the speed at which the Milky Way halo is rotating, a discovery that could provide new clues on how galaxies form and evolve.

Our galaxy is surrounded by a gaseous halo that extends for many hundreds of thousands of light-years from the center. It has a mass comparable to the Milky Way itself and it was believed to be still, compared to our quickly rotating galaxy.

"This flies in the face of expectations," lead author Edmund Hodges-Kluck said in a statement. "People just assumed that the disk of the Milky Way spins while this enormous reservoir of hot gas is stationary – but that is wrong. This hot gas reservoir is rotating as well, just not quite as fast as the disk."

The gas in the halo is incredibly hot, millions of degrees, but very spread out so it's difficult to estimate how quickly it's moving. The researchers had to carefully detect movement as the gas moved in front of very bright extragalactic sources, like active supermassive black holes and quasars.

In a paper published in the Astrophysical Journal, they reported that the gas is moving at about 180 kilometers per second (400,000 mph), which is only slightly slower than the rotational velocity at the rim of the Milky Way (240 km/s, 540,000 mph).

"The rotation of the hot halo is an incredible clue to how the Milky Way formed," continued Hodges-Kluck. "It tells us that this hot atmosphere is the original source of a lot of the matter in the disk."

Galaxies are believed to have formed when intergalactic materials began to fall into the large gravitational wells formed by dark matter. The rotation of the halo tells us how quickly the material must fall towards the center, and also how quickly the Milky Way came together.

"Now that we know about the rotation, theorists will begin to use this to learn how our Milky Way galaxy formed – and its eventual destiny," added Professor Joel Bregman, co-author of the study.

Frightful mysteries of ancient mummies were untied with X-ray scans

Updated 04/05/2020

Scientists have conducted a new study to see if some of the most popular myths about mummies or not a grain of truth.

"Mummification was practiced in Egypt for more than 3,000 years, and the practice was changed in different times and places. In the past, we have looked at one, two mummies and we get a conclusion, but now we have much more technology nondestructive and a wealth of medical information that we rely on, "said anthropologist Andrew Wade, from the University of Western Ontario.

In the next issue of the Journal of Archaeological Science, Wade and his teammate Andrew Nelson examined radiographs of a total of 84 mummies in museums around the world. Their goal was to approve or disapprove some of the oldest and strangest information on ancient mummies. This information was and that during mummification, rulers and their successors brains were removed through the nose. Another information is so that internal organs were removed from the rich mummies.

Following our analysis based on X-ray scans, it was found that the mummification process was more complicated than we imagine.

Part of the blame for this confusion Greek historian Herodotus gate which noted in 440 BCE a description of the mummification process, following a visit to Thebes. Then he wrote that during the mummification of the rich is made interventions to remove the internal organs and the brain. Instead, for the poor, who were buried without being wrapped in cloth, resorting to a cheap technique of dissolving parts.

Ancient Egypt How were mummies made?. Herodotus

"In fact, it seems that Tut's time, almost everyone could afford to be mummified," says Wade after analyzing mummies. Then Pharaoh Tutankhamen died around 1323 î.e.n, long before Herodotus, and after the death of Pharaoh, mummification became increasingly popular.

But sometimes things were happening and as described by Herodotus. For example, if the priest Nesperennub, looked at the British Museum with the help of a CT performance, it was found that during the mummification process and has been removed brain through the nostrils, and his organs, such as lungs were stored in containers.

Nesperennub Mummipedia Wiki

However, other times, not performed in accordance with mummification Herodotus. Sometimes the lungs and other organs were left inside mummies, and the brains were removed only in certain cases. Moreover, there were cases where, for removing the brain was a hole in the place where the spine meets the head.

On the other hand they were discovered instances where the mummy's head was filled with resin, and scientists explain this by suggesting that it is possible that golden hue liquid resin to be associated with the sun and divinity. However, the brain was not receiving significant attention at the time. Instead, it was observed that the length of cloth used to wrap the deceased's head vary significantly from case to case, depending on who achieve process. Following investigations it was found that in some cases, are used for head and 55 meters of cloth.

Moreover, the study does not find evidence concerning what Herodotus describes as inexpensive technique which would have involved the use of cedar oil to dissolve the entrails of the mummy. Scientists believe that the substance would be too expensive for such use. Instead, they say for embalming animals would be used turpentine (liquid obtained by distilling pine resin). Therefore, it is possible that Herodotus to be confused with the animal conservation method used for humans.

A practice that seems to have been reserved for the elite is linked to heart organ which was the center of conscience and morality in Egyptian mythology. "The whole idea was you could enjoy the afterlife, and certainly for this you needed heart," said Wade.

However, the analysis indicated a significant lack of heart among mummies, which suggests that keeping the body in the afterlife was reserved for the elite. As the "Book of the Dead" is prohibited sharing secrets related to the procedure of mummification, Wade speculate that it could have that common people do not even have been aware of the fact that they remove the heart to allow them to of a privileged elite. Moreover, all heart, the confection shaped stone jewelry beetles that lived over organ.
