Snails have simple emotions and memory, In scientists research

Russian scientists came to unexpected conclusions, discovering that grape snails have simple memory and emotions.

Russian academic Pavel Balaban, a member of the Russian Academy of Sciences, said in an interview with the Russian Novosti news agency: "The snail has all the hormones associated with emotions, when certain areas of its brain are stimulated, as a person feels positive or negative feelings."

According to him, during these experiments, scientists proved that snails also have "arrows of love." That is, like Cupid (the messenger of love), he is able to "infect" the snail he likes with a calcium needle and after 15 minutes fertilizes her.

"The snail's love arrow is an element of social interaction, they use it when breeding, when one of the partners is not satisfied with something," the academic says, explaining.

And he adds, newborn snails have a miraculous ability, as they do not feel fear for a period of 3-4 weeks after their birth.

He says: "She has no sense of pain because she does not have neurotransmitters. Perhaps this is because the young ones live in the same nest and can leave it without fear."

An "invisible monster" Scientists solve the mystery of a wild black hole in universe : Myspace

Scientists think they've come up with an explanation for what they initially believed to be a "runaway" black hole speeding through the universe, which has been the subject of much debate in the scientific community.

Scientists have discovered a chain of stars 200,000 light-years long that was originally thought to follow a runaway black hole described as an "unseen invisible monster", but it may actually be a disguised galaxy belonging to a relatively common type of galaxy known as flat galaxies.

Astronomers announced the "runaway" black hole, which has a mass of 20 million suns, earlier this year, based on observations of the Hubble Space Telescope.

The team was amazed at the size of the tail of stars that the black hole appears to be dragging away from its home galaxy.

It is believed that this stellar tail arose when the black hole, which is moving at a great speed equivalent to covering the distance between the Earth and the Moon in just 14 minutes, made its way through the gas, causing the formation of dense regions and the birth of stars in its wake.

But scientists weren't sure why this black hole wasn't greedily gulping down gas and creating more turbulence as it moved through it. The galaxy from which the supermassive black hole was ejected was also supposed to be surrounded by a huge amount of gas.

These factors cast some doubts about the "runaway black hole followed by stars" scenario, and multiple teams of astronomers have begun to explore different, less exotic explanations for the observations.

In a recent study, a team from the Institute of Astrophysics of the Canary Islands (IAC) suggested that the intriguing observation could in fact be a galaxy without a bulge appearing at the edge. These thin or flat disk galaxies are fairly common in the universe.

"The motions, size and quantity of the stars fit what was seen in galaxies within the local universe," said team member and researcher at the Institute of Astrophysics of the Canary Islands, Jorge Sanchez-Almeida, in a statement.

He added, "It is very satisfying to find a solution to this puzzle. The new proposed scenario is much simpler. On the other hand, it is unfortunate, because runaway black holes are expected, and this may be the first scenario that can be observed."

To examine their interpretation of the Hubble observations, the team compared the supposed trail of stars to a well-known, less bulging galaxy called IC5249. This thin galaxy is located near our own Milky Way galaxy, and has a cluster of stars similar to the "tail" observed by Hubble.

Observations of the two dissimilar objects - the tail of the putative runaway black hole and IC5249 - were surprisingly similar.

"When we analyzed the velocities of this distant structure of stars, we realized that they were very similar to those obtained from the rotation of galaxies. So we decided to compare a much closer galaxy and found it to be extraordinarily similar," said co-researcher and team member Mireya Montes.

The relationship between the mass of what the team assumed to be a flat galaxy and its top speed of rotation convinced the team that the hypothesized "star tail" was in fact a galaxy behaving like a galaxy. However, this conclusion is unlikely to lead to a weakening of interest in this object.

Astronomer Ignacio Trujillo added: "It is an interesting object because it is a very large galaxy at a very great distance from Earth, where the majority of galaxies are smaller.

An Australian scientist claims to have solved the mystery behind the "Devil's Triangle" Bermuda and Puerto Rico

An Australian scientist has claimed to have solved the mystery behind the Bermuda Triangle, a region in the North Atlantic Ocean between Florida, Bermuda and Puerto Rico famous for stories of disappearing planes and ships.

For decades, the Devil's Triangle, as it is also known, was infamous as a hotspot for unexplained disappearances. This has sparked many speculations, theories and even supernatural explanations, ranging from water sinks, methane bubbles or magnetic field imbalances, to wormholes, the long-lost technology of Atlantis or extraterrestrials.

However, Karl Krushelnicki argues that the truth behind the mystery of the Bermuda Triangle is much simpler, as he believes it is only due to a combination of sheer probability (the probability of random occurrences), human error and weather, rather than the occurrence of any kind of unusual phenomenon.

As a result of his studies, Krushelnicki argued: "The number of ships and planes lost in the Bermuda Triangle is the same as anywhere in the world on a percentage basis. It's close to the equator, near a wealthy part of the world, America, so you have a lot of traffic."

In fact, Krushelnicki claims, the area where a group of five US Navy bombers known as Flight 19 disappeared without trace in 1945 has a similar rate of missing boats and planes than anywhere else in the world. Boffin of Sydney University believes human error and bad weather are the most likely causes of anything untoward, rather than alien abductions and outlandish theories cited by some theorists.

Speaking of Flight 19 itself, Krushelnicki, the 14-man crew commander, Lieutenant Charles Taylor, who "had a history of getting lost and abandoning his plane twice before," explained that human error in this famous tragedy is likely.

He went on to claim that radio transcripts prior to Flight 19's disappearance indicated that the crew had become unsure of its location.

Krushelnicki explained: “If you read radio texts, some novice pilots say: “Why don't we fly to the west?”, And the pilot says: “Why don't we fly to the east? "

In fact, the transcripts revealed that Lt. Taylor thought his compass had malfunctioned and that he was over the Florida Keys. However, subsequent analysis showed that it was further to the southeast in the Bahamas.

Krushelnicki's claims were first reported in the British newspaper The Independent in 2017, but resurfaced again this month in Popular Mechanics magazine, after he again stated that human error and bad weather were likely behind all the disappearances. Fox News reported.
