Those on the autistic spectrum use prior information but update it slowly, how we process information?

Researchers who studied how we process information have found that dyslexics have difficulty learning from stimuli to which they were previously exposed, while those on the autistic spectrum use prior information but update it slowly

None of us sees the world as it really is.When we see, hear, or smell what is around us, we do not passively absorb the information that exists in the world: the moment it is absorbed by our senses, we process the information in part based on what we have seen,heard and smelled in the past. For example, when our dog runs to the end of the street, we realize that it will not get smaller just because it's getting less space on our retina now. Similarly, we do not think the red swing in the garden changed color on a cloudy day, although objectively, the wavelength it returns is different from the one it brought back when it was sunny. Different perceptual biases are built into the way we process information, allowing us to use a wider context to understan…

Rare microscopic creatures that are genetically different from any of the other species known to science

Canadian researchers have found rare microscopic creatures that are genetically different from any of the other species known to science
Biologists use a method called systematics to classify living organisms into groups and explore their relationship. For example, the lions are species of the genus Panther, belonging to the cat family, belonging to the mammalian department, which belongs to the animal kingdom. The classification indicates a connection to a common ancestor and a level of "familial" closeness among various creatures, including those already extinct, and by means of which a sort of a family tree called "an evolutionary tree of life" is created. In the past, the classification was based on external characteristics such as appearance, but nowadays the classification is based primarily on genetic similarity in DNA.

A few years ago, Y. Eglit, a student from the University of Deliose, Canada, traveled across Nova Scotia and collected dirt from the area. Wh…

A new study found the same genetic signature associated with monogamy in species of evolutionarily distant animals, including mammals, birds, amphibians and fish.

Same genetic signature associated with monogamy in mammals, birds, amphibians and fish.
Monogamy evolved in many different groups of animals.Prairie voles, little rodents who live in North America, do not believe in free love. When they choose a partner, they stay with them for life, raise the offspring together and cooperate in preserving the territory. Monogamy is not unique to voles of course: we observe it in other mammals and also in birds, amphibians and even fish. It seems to have evolved again and again, independently, in different groups of animals. A new study suggests that in each such case, genes responsible for monogamous behavior were involved in the development of monogamous specie from an ancestor that wasn't monogamous.

A study compared monogamous animals to five non-monogamous animals.Researchers from universities in the United States and the United Kingdom compared five monogamous species to five non-monogamous species. For example, they examined the Meadow vole a…

Will aliens interpret the first message from humanity to them as a cyber attack?

This hypothetical issue was discussed at a conference held at the Bradford Science Festival, which dealt with the question of what message should be transmitted to aliens and whether we would be the initiators of the broadcast. 
The discussion was held with the aim of promoting the - project which offers $ 1 million to the best message provider. The competition is open to the general public.
The issues discussed at the Science Festival organized by the British Scientific Society, and was about formulating the first message for intelligent aliens and whether to launch it deliberately or merely to send it in response to a broadcast from an alien civilization.

The speakers at the event were members of the British branch of seti, who were competing for a $ 1 million prize from Russian Internet billionaire Yuri Milner as part of a larger $ 100 million project initiated by Russian billionaire Yuri Milner, in which Professor Stephen Hawking is also involved. …

The Iranian missiles were completely destroyed: the results of the Israeli attack in Syria are exposed.

The results of the Israeli attack in Syria are exposed.

After the Israeli attack on the International Airport in Damascus, ImageSat International (ISI) released two satellite photographs showing the ammunition depots before and after they were bombed from the air. The pictures show the warehouses, reportedly used for Iranian ammunition, open and active, with trucks running alongside them. The dimensions of the trucks, as well as the warehouse itself, correspond to the assessment that this is a warehouse used to store missiles. The "after" picture shows that the warehouse was completely destroyed.

According to reports in the Syrian media, the attack was carried out on Friday night, in areas that according to foreign reports have been attacked many times in recent years. The Syrian news agency SANA reported that Syria's air defense systems intercepted eight hostile targets, and the Foreign Ministry in Syria accused Israel for the attack, saying it was part of Israel's …

IBM unveiled the IBM Q System One at CES, The world's first of its kind quantum computing system for scientific and commercial use

These systems were designed by IBM scientists, system engineers and industrial designers, enabling the first time to operate a computer based on quantum processing outside the research labs.

The computing power of quantum systems is immeasurably superior to the capabilities of classical computing systems and is designed to deal with problems that are too complex for today's computers. Applications of such systems may include complex problem solving related to molecular and chemical interactions, development of new drugs, new materials, financial modeling, risk management, or improvement of large systems.
Classic computers are built into a package that combines a large number of components into a single architecture. IBM has implemented a similar approach to quantum computing and IBM Q systems one combines thousands of components working together to offer the most advanced computing device of its kind operating in the cloud environment. It is one of the most sophisticated, modular a…

How the Moon causes tides in the oceans on both sides of the Earth at the same time.

Tides are cyclical changes in sea level, caused by the influence of the moon's gravitational force on Earth. At any point in the world, the tides occur twice a day, in cycles of 12 hours and 25 minutes, half the time it takes for each point on Earth to pass in the area closest to the moon. At any given moment, the tide occurs in two separate regions of the earth. One is on the closest side to the moon, the other on the opposite side, the farthest from the moon. The tide can be equated with a kind of ellipse of water revolving around the solid earth, whose long axis is always parallel to the axis connecting the center of the earth to the moon.

There is a misconception that the gravity of the moon is the one that "draws" water. But in fact, changes in the surface of the oceans occur as a result of another physical phenomenon, which explains why the tide is also occurring on the side of the Earth far from the Moon, a fact that the moon's gravity does not explain.

New Horizons Spacecraft Took a Close Look at Pluto, NASA may Detect More Celestial Bodies in the Kuiper Belt.

The New Horizons spacecraft was launched in 2006 to probe the planet Pluto.
After almost a decade of flying, she passed by him in July 2015 and took a close look at Pluto and his moon. Long after the transition, the spacecraft continued to transmit images of Pluto and other information about the planet and its moons. Pluto is the largest known object in the area known as the Kuiper Belt, a vast area containing asteroids and other celestial bodies in the outer part of the solar system. After the passage near the dwarf planet, the plan was for the spacecraft to take a closer look at other objects in the Kuiper belt, and the search for the next target began before it approached its original destination. 
The object eventually selected was discovered in 2014 by observations of the Hubble Space Telescope, made just for this purpose. Its official name is 2014MU69, and the name is expected to be approved only after the spacecraft passes by it. The discovery is little more than the very existe…
