Aparece en Borneo una ave que se creía extinguida desde hacía casi 200 años

A bird has been unexpectedly rediscovered in Borneo 172 years after its only description, according to inform BirdLife International. Specifically, two inhabitants of the South Kalimantan province of Indonesia have found it.

Is about black-browed cowbird.

The biggest enigma of Indonesian ornithology

The black-browed cowbird was described by the French ornithologist Charles Lucien Bonaparte in 1850. Its description was based on a specimen collected sometime in the 1840s by the German geologist and naturalist Carl ALM Schwaner, during his expeditions to the East Indies.

Black Browed Babbler

Since then, no other specimens or sightings have been reported. Until now. As explained Panji Gusti Akbar, lead author of A study describing details of the rediscovery:

We also know what the black-browed cowbird really looks like: the bird photographed now showed several differences from the only known specimen, specifically the color of the iris, beak, and leg. These three parts of a bird's body are known to lose their dye and are often artificially colored during the taxidermy process. The discovery also confirms that this species continues to exist despite massive deforestation and habitat conversion in this little-known part of Borneo. Therefore, there is a very high possibility that it will be seriously threatened by habitat loss.

Imagen sorprendente del lado nocturno de Venus desde una distancia de 12.380 kilómetros gracias a la sonda solar Parker

This amazing image of the night side of the planet Venus from a distance of 12,380 kilometers has been captured by the Wide Field Imager for Parker Solar Probe, or WISPR.

The capture occurred unexpectedly during the mission's third Venus gravity assist on July 11, 2020.

WISPR

WISPR is designed to take images of the solar corona and inner heliosphere in visible light, as well as images of the solar wind and its structures as they approach and fly by the spacecraft.

Wispr Venus Image

WISPR is designed and tested for visible light observations, so they expected to see clouds, but the camera looked directly at the surface. So, effectively captured thermal emission from the surface of Venus, detected a bright rim around the planet's edge that may be nightglow: light emitted by oxygen atoms high in the atmosphere that recombine into molecules on the night side.

The prominent dark feature in the center of the image is Aphrodite Terra, the largest mountainous region on the surface of Venus. The feature appears dark due to its lower temperature, about 30 ºC colder than its surroundings.

Wispr Venus Annotated

On January 29, 2020, the trajectory of the Parker Solar Probe took the spacecraft to a distance of approximately 18.6 million kilometers from the Sun, more than 5 million kilometers closer than previous flybys, so this, broke his record.

Reinforcement learning algorithms are better at playing classic video games than humans and other AI systems

By portal-3

Los algoritmos de aprendizaje por refuerzo son mejores jugando a videojuegos clásicos que los humanos y otros sistemas de IA

A set of reinforcement learning algorithms have proven to be better at playing classic video games than human players or other artificial intelligence systems.

The algorithms have been developed by a team of researchers at Uber AI Labs in San Francisco.

Future applications

The reinforcement learning algorithms They learn to do things by synthesizing the information provided by a large set of data: they recognize patterns and use them to make conjectures about new data. But such algorithms tend to run into problems when they encounter data that doesn't fit other data. Problems that have been corrected in this new development.

To do this, they have added an algorithm that remembers all the paths that a previous algorithm has taken while trying to solve a problem. When it encounters a data point that doesn't appear to be correct, it goes back to its memory map and tries another route.

The researchers They tested their new approach by adding rules from a video game and an objective- Get as many points as possible and try to achieve a higher score each time. Then they used their system to play 55 Atari games. The new system beat other AI systems 85.5% of the time. He did particularly well in Montezuma's Revenge, obtaining a higher score than any other artificial intelligence system and even breaking the record of a human.

The researchers believe that their algorithm could be transferred to other applications, such as image or language processing by robots.

Books that inspire us: 'Caught by the tongue' by Sheila Queralt

By portal-3

Libros que nos inspiran: 'Atrapados por la lengua' de Sheila Queralt

Sheila QueraltIn addition to being one of the few specialists in the world in anonymous analysis, she has a doctorate in Language Sciences and works as a judicial expert in Forensic Linguistics.

Your book Trapped by the tongue. 50 cases solved by forensic linguistics It is a casual approach to his work, as well as all the facets of this discipline, the curiosities, and the most notorious cases in history.

Miss Marple of the tongue

Sheila is like Miss Marple either sherlock holmes, but its clues are based exclusively on the characteristics of the language: the way a person expresses themselves, both orally and in writing, since in this one can find singularities that offer a lot of information. Even to the point of being able to find out who wrote an anonymous letter.

We are, therefore, before a type of research that is very little known and that is often confused with other disciplines. For example, a forensic linguist does not analyze the shape of the letter (that is what calligraphers do), nor do they extract personality traits of the author from their signature (that is what graphologists do). Nor does it carry out psychological profiles of the perpetrator of a crime, a task carried out by criminal profilers.

Trapped by the language: 50 cases solved by Forensic Linguistics (LAROUSSE – Illustrated/Practical Books – Art and culture)

What does a forensic linguist, for example, is to find a clue in the recordings of Anabel Segura's kidnappers or the alleged drug trafficker from Barcelona who spent 626 days in an Italian prison, and other cases that are astonishing due to the degree of scrutiny to which any sound, any detail in the accent, any particularity when writing, in order to find out not only the identity of the author, but a whole constellation of contextual data.

Furthermore, the book is not written in a technical or boring way, but rather the author accompanies us page by page almost hand in hand, contaminating us with her good humor and enthusiasm, until we feel what day to day work is like.

To discover a little more about the book and the author, you can do so in the following interview that she was kind enough to grant me:

It is confirmed that this kangaroo is the oldest cave painting in Australia and is 17,500 years old

By portal-3

Se constata que este canguro es la pintura rupestre más antigua de Australia y tiene 17.500 años

Using radiocarbon dating of 27 mud wasp nests, collected from more and less than 16 similar paintings, it has been confirmed that the rock art depicting the kangaroo that you can see at the head of this entry is the oldest art found in Australia.

According to him study that details it, published in Nature Human Behavior, and carried out by researchers from the University of Melbourne, is has placed the painting between 17,100 and 17,500 years ago.

The kangaroo is painted on the sloping roof of a rock shelter on the Unghango clan estate in Balanggarra Country, above the Drysdale River in the north-eastern Kimberley region of Western Australia. As explained by the postdoctoral researcher Dr. Damien Finch, who pioneered the exciting new radiocarbon technique:

We will never be able to know what was on the artist's mind when he painted this work more than 600 generations ago, but we do know that the naturalistic period dates back to the Last Ice Age, so the environment was cooler and drier than today.

The next step for researchers is to date more wasp nests in contact with this and other styles of Kimberley rock art to establish, more precisely, when each artistic period developed when it began and when it ended.

What 'Wandavisión' teaches us about how to deal with the death of a loved one: it can be so painful that you can get sick

By portal-3

Lo que 'Wandavisión' nos enseña de cómo afrontar la muerte de un ser querido: puede ser tan dolorosa que puedes enfermar

In the period of three months after the death of a spouse, widows and widowers are more likely to manifest risk factors related to cardiovascular disease and death, suggests A study published in Psychoneuroendocrinology, showing higher levels of pro-inflammatory cytokines (immune markers that indicate inflammation in the bloodstream) and lower heart rate variability (HRV).

Wanda's story in the Disney + Wandavision series (Scarlet Witch and Vision) is traumatic, painful and tragic. The first episodes show Wanda and Vision (played respectively by Elizabeth Olsen and Paul Bettany) as a happily married couple living like in an old sitcom from the 50s, then 60s, then 70s. Westview seems like the refuge for that pain.

Westview and your distorted reality

When a person has lost a partner or spouse, they are most commonly living in an 'altered reality'. The people we love, especially our partners and/or spouses, they give meaning to our world. They connect us with our reality. They help us anchor ourselves and are part of our role and identity.

During grief, then, the world can seem like a strange and terrifying place, in which one feels the need to control everything around them, to protect themselves. Have a sense of control over everything that is out of control. Sometimes, then, we need to put ourselves in a protective bubble, like an oxygen tank. In the case of Wandavision it is Westview.

This happens because, after the death of the loved one, both tangible and intangible losses occur, such as loss of home, loss of identity, loss of sense of security, loss of companionship, loss of customs and habits, loss of trust, loss of family role, loss of financial security, loss of purpose, loss of trust, loss of intimacy, as well as the loss of future hopes and dreams.

In some cases, grief can be complicated or pathological, as it deeply interferes with our abilities to face life and adapt to it, as suggested by This studio. Reasons for this may include the type of repeated losses that Wanda's character experiences. People experiencing maladaptive grief may show continuous pain, anger, anguish, sadness, bitterness, destructive to themselves or others, or efforts to escape from responsibilities or others.

Wandavision Estreno Horario Colombia 15 De Enero Marvel Studios 883561

Wanda teaches us that we can be powerful and fragile. It takes strength to fight to survive the deep pain of grief.. Therefore, as already happens in the movie Pleasantville (1998), if we have a special power, that power may also be oriented towards escape from reality in a much more tangible way. In this case, taking refuge in an Arcadian past where everything seemed simpler. Where, in addition, there were still the canned laughter that accompanied the characters in all their situations.

The canned laughterTherefore, they are like a happiness spell, as you can see in the following video, which also explains who invented them, as well as other methods to laugh more, be happier and, ultimately, be less alone in the world. universe:

If you are intelligent you are more likely to be intolerant than if you are not so intelligent.

By portal-3

Si eres inteligente es más probable que seas intolerante que si no eres tan inteligente

We are all crossed with biases. We all tend towards tribalism. To fall in love with ideas that form the foundations of our tall, beautiful and fragile houses of cards. Naturally, We are all intolerant of outgroup members. (and with all the ideas that come from there).

The difference is that smarter people have more sophisticated tools to advance justifications for that intolerance. It doesn't matter what your political point is: if you are smarter you can probably be more Machiavellian when it comes to displaying your intolerance.

Liberals and conservatives

This is what it suggests a new study published in Journal of Personality and Social Psychology. Specifically, it establishes that conservative Americans are ideologically more intolerant than liberals, because the former are more politically sophisticated.

As the authors explain:

High cognitive ability allows individuals more cognitive resources, making them better able to reason about and justify their political ideology. From this perspective, cognitive ability influences ideological intolerance because those with higher cognitive ability are likely to have greater political sophistication than those with lower cognitive ability and, as a result, are more likely to rely on their ideology when forming attitudes toward the ideological outgroup, which makes the difference with the outgroup more prominent.

This relationship between ideology and exogenous intolerance also seemed to be influenced by extremism. Among both conservatives and liberals, extreme ideological views were linked to greater intolerance toward the out-group.

The researchers note that when comparing data from the two survey-based studies, it appeared that outgroup dislike was much higher in the recent 2010s sample compared to the 1980s sample. which likely reflects the greater polarization of American politics.

For this reason, more examples of liberticide also appear., both on one side and the other. Nobody pursues true freedom of expression. There are always ideological red lines, health cordons, cultural cancellations, even murders or attacks. There is always some faculty that does not want, by force, a speaker to present their ideas because they consider that their ideas are monstrous.

Therefore, in all countries, and until very few years ago, it was normal for genocide to be defended by intellectuals of international stature. Right now we live in a strange time where a minimal percentage of people believe that everyone should say theirs, and that in the event that two rights collide, we must ensure that freedom of expression prevails.

Maybe that small percentage will disappear again soon. Let's do everything possible to prevent it from happening. So that some do not think that others are slobs and that they deserve censorship, jail, cancellation or cordon sanitaire. So that at least a small percentage of people do not think that the solution to a perfect world It's about eliminating those you don't like:

The golden mirror for James Webb is the most sophisticated mirror ever built and will expose the universe

By portal-3

El espejo dorado para el James Webb es el más sofisticado espejo jamás construido y desnudará el universo

The mirror is so big that NASA doesn't fit inside any rocket, so to launch it into space we must fold it and finally deploy it into orbit to become part of the James Webb Space Telescope.

The James Webb Space Telescope will be able to image the Universe in the deepest and most powerful way possible. This mirror has seven times more light-gathering power than Hubble's.. It is the most sophisticated that has been built to date.

The mirror that will reveal the universe

He James Webb Space Telescope (James Webb Space Telescope (JWST)), will be a space observatory developed by collaboration between approximately 17 countries. But its golden mirror is particularly prodigious.

a

The sensitivity of a telescope It is directly related to the size of your mirror, which determines how much light the telescope can collect from the objects it observes. So the Northrop Grumman engineers behind the James Webb Space Telescope had to go to great lengths to build such a structure.

They had to design a mirror with a diameter of 6.5 meters that can survive the launch of a rocket into space, orbit the Earth for 5 to 10 years and maintain its shape at temperatures close to 220 ºC. And, as said, it is not a single piece, but a series of 18 segments made of beryllium, a rare metal that is strong and light. Engineers coated them with a microscopically thin layer of pure gold for maximum reflectivity..

Each of these hexagonal-shaped mirrors has a diameter of 1.32 meters and has a mass of around 20 kg. Small motors control each segment and can move up and down, left and right, and back and forth. This is necessary to unfold and focus the mirror. The curvature of each segment is also adjustable.

When placed together in a honeycomb pattern, these segments form an effective surface that will be 6.5 meters in diameter.

Jwmirrors2

Planning for Webb began in 1989, a year before NASA launched the Hubble telescope into orbit around Earth. Development began in 1996. NASA moved up an initial launch date from 2007 to 2011, then 2014, then 2018, and now, more than 30 years later, the telescope is expected to launch in 2021.

14,974 dust storms mapped on Mars over eight years

By portal-3

Se mapean 14.974 tormentas de polvo en Marte durante ocho años

Astronomers at the Harvard Center for Astrophysics have used daily global maps from NASA's Mars Global Surveyor and Mars Reconnaissance Orbiter missions to Mars for eight years. to map nothing less than 14,974 dust storms larger than 100,000 square kilometers and lasting more than a day.

Information for future missions

In this way, an attempt has been made to analyze particularities and patterns in storms that significantly affect the transmission, thermal structure and circulation of the Martian atmosphere.

All this information is a very valuable new resource for modeling the Martian atmosphere and mission planning.

Huge dust storms, which persist for weeks and even months, obscuring the entire planet, can arise suddenly, although they are more frequent after the planet's perihelion and in the Southern Hemisphere, when it is the end of spring there, They are caused by winds of more than 150 km/h.

Just as on Earth a wind of 50 to 60 km/h is enough to raise clouds of dust, on Mars, given the tiny density of the air, only a gale of about 200 km/h can produce the same effect. These storms can reach planetary dimensions.
