Having children only increases your happiness if you can pay the bills (and up to 10 years of age).

Tener hijos solo aumenta tu felicidad si puedes pagar las facturas (y hasta los 10 años de edad)

It doesn't matter that the planet is increasingly in environmental danger, or that we are already riding the second wave of a global pandemic that could condemn us to years or decades of poverty, people continue to have children. So we have to wonder if having children really provides enough happiness to ignore those details.

The answer is ambiguous: at first, according to this study suggests, Yeah. Having children is like treating yourself to any big whim: a trip, a new car, etc. However, there are some considerations to keep in mind: If there are financial problems, the child does not bring more happiness.

The happiness of the first years

If there are financial difficulties associated with the children, having them does not increase parents' happiness significantly. Furthermore, even if it does, once the children are over ten years old, the added happiness effect recedes a little, especially in adolescence: we do not know if because the children become more unbearable or because the novelty effect is left behind. .

In the study, published in Journal of Population Economics, also point out that not all children are equal, and stepchildren They tend to have a more negative correlation than the children of the current relationship.

To carry out the study, international data was taken into account, including more than one million observations on Europeans during 11 years of Eurobarometer surveys.

Other studies suggest that having children does not necessarily increase net happiness; Even, on average, having children means being less happy than not having them because we do not control all the problems that may arise, as explained Gary Marcus in his book Kluge:

Although the climaxes (“Daddy, I love you”) can be spectacular, on a day-to-day basis, most of the time spent caring for children is simply work. In “objective” studies that ask subjects about their level of happiness at random times, childcare (a task with a clear adaptive advantage) oscillates somewhere between housework and television, well below sex and cinema. Luckily, from a species perpetuation perspective, people tend to remember (intermittent) climaxes better than the drudgery of daily diapers and chauffeur service.

Smaller, more comfortable and easier to use: this is the new toilet that will be installed on the International Space Station

By portal-3

Más pequeño, más cómodo y más sencillo de usar: así es el nuevo inodoro que va a instalarse en la Estación Espacial Internacional

Aboard a US Cygnus replenishment freighter, October 3 will arrive at the International Space Station (ISS) the Universal Waste Management System (UWMS).

A new toilet that is smaller, more comfortable, easier to use and will be able to serve a larger crew.

UWMS

The new toilet features a 65% smaller and 40% lighter construction than the current space station toilet. Improved integration with other components of the space station's water system will help recycle more urine, which, yes, astronauts drink after filtering and processing it.

Uwms Diagram Web Feature V3 10

"We recycle about 90% of all water-based liquids on the space station, including urine and sweat," explains the NASA astronaut Jessica Meir. “What we are trying to do aboard the space station is mimic elements of Earth's natural water cycle to recover water from the air. And when it comes to our urine on ISS, today's coffee is tomorrow's coffee!

In the absence of gravity, space toilets use airflow to draw urine and feces from the body and place them in the appropriate receptacles. A new feature of the UWMS is the automatic start of airflow when the toilet lid is lifted, which also helps with odor control.

It also features a more ergonomic design that requires less time to clean and maintain, with durable, corrosion-resistant parts to reduce the likelihood of off-schedule maintenance.

For added privacy, the toilet is located inside a cubicle like in a public bathroom on Earth.

The UWMS seat may seem uncomfortably small and pointy, but in microgravity it is ideal. Provides ideal body contact to make sure everything goes where it should.

Toilet paper, wipes and gloves are disposed of in ziplock bags. Solid waste in individual waterproof bags is compacted into a removable fecal storage container. A small number of fecal containers are returned to Earth for evaluation, but most are loaded onto a cargo ship that burns upon re-entry into Earth's atmosphere.

According to this model there are up to six levels of critical thinking: from thoughtless thinkers to master thinkers.

By portal-3

Según este modelo hay hasta seis niveles de pensamiento crítico: de pensadores irreflexivos hasta pensadores maestros

We all like to be right. Reduce complex issues down to make them simple and, if possible, Manichean. We are also happy to slip superficial thoughts into typical bar conversation, more cathartic than reflective.. We even like to debate but not so much to confront ideas and enrich our own, but as a social act, a dance-like interaction.

However, that does not mean that we all have to be like this all the time or that we are doomed to be continually biased. There are people whose thinking is more or less sophisticated. And the importance of critical thinking in our daily lives cannot be underestimated, especially in these confusing times, so punctuated by rapid and often misleading information.

The theory of stages of critical thinking development, devised by psychologists Linda Elder and Richard Paul, can help us gauge the sophistication of our current mental approaches and provides a roadmap for the thinking of others.

The researchers identified six predictable levels of critical thinkers, from the lowest in depth and effort to advanced mental masters, who are always one step ahead. To level up the pyramid you just have to make an effort, train, as if you were going to a gym, because it would be rare for a person to be born spontaneously on the cusp.

Next, the six stages of intellectual thinking.

1. Thoughtless thinker

They are people who do not reflect on thought and the effect it has on their lives. As such, they form opinions and make decisions based on biases and misconceptions while their thinking does not improve. They also do not consistently apply standards such as accuracy, relevance, precision and logic..

As the psychologist points out Gary Marcus in This book will make you smarter:

When two people disagree, the cause is very often to be found in the fact that their previous convictions lead them to remember (or focus on) different pieces of information.

Most university graduates, for example, could still be on this first step. Social networks are a good place to see how this type of reasoning proliferates (due to the structure of the social network itself, not necessarily because the thinker is terrible, per se).

2. Questioned thinker

They can recognize that their own mental processes may have many flaws. However, they may not be able to identify all defects.

A questioning thinker may have the sense that sound thinking involves navigating assumptions, inferences, and points of view, but only at an initial level. They can also detect some cases of their own self-deception. As the philosopher explains Julian Baggini in Do they think we are stupid?: We prefer “that is true” or “that is false” to “the factual part of that information is true, but its supposed advantages are not real.”

3. Beginning thinker

They can begin to look at the concepts and biases underlying their ideas. Additionally, these thinkers develop higher internal standards of clarity, precision, and logic, realizing that your ego plays a key role in your decisions.

There is some capacity to receive criticism of their mental approach, even though they still have work to do and may lack sufficiently clear solutions to the problems they detect.

4. Intern Thinker

This type of more experienced thinker not only appreciates his own shortcomings, but has the ability to deal with them. A thinker at this level will practice better thinking habits and analyze their mental processes regularly. With everything, They can still fall prey to egocentric and self-deceptive reasoning..

In short, you will begin to take into account some notions such as those introduced John Allen Paulos in A mathematician reads the newspaper:

What difference is there between the empirical and the a priori proposition, between scientific induction and mathematical induction. Is a certain consequence valid in both senses or is its inverse false?

5. Advanced thinker

The advanced thinker is comfortable with self-criticism and does it systematically, seeking to improve. Among the key traits required for this level are 'intellectual insight' to develop new habits of thought, 'intellectual integrity' to 'recognize areas of inconsistency and contradiction in one's life, 'intellectual empathy' to put oneself on the spot. place of others in order to genuinely understand them, and the 'intellectual courage' to confront ideas and beliefs that they do not necessarily believe in and towards which they have negative emotions.

This type of thinker is no longer burdened by the so-called effect Lake Wobegon, as Kathryn Schulz explains in her book In defense of error:

Many of us go through life assuming that we are essentially right, always and about everything: about our political and intellectual convictions, about our religious and moral beliefs, about our appreciation of others, about our memories, about our way of thinking. understand what is happening. If we stop to think about it, anyone would say that our usual situation is to unconsciously assume that we are very close to omniscience.

6. Master thinker

An expert thinker achieves great understanding of deep mental levels, and is strongly committed to being fair and gain control over your own egocentrism.

Such a high-level thinker also exhibits superior practical knowledge and insight, always re-examining his assumptions. looking for weaknesses in your logic and or the existence of biases.

A skilled thinker would also not bristle at being intellectually confronted and would spend a considerable amount of time analyzing his or her own responses. Nor will it label those who defend diametrically opposed beliefs as "reds", "cavemen", "liberal lunatics", "right-wing bastards" and a long and creative etcetera. It will analyze ideas and not people or groups. He will flee like the plague of ad hominem. Will be vaccinated for the call Dunning-Kruger effect, that is to say, the inability of a subject to recognize his own ineptitude.

In times when those offended are bothered by any statement that even slightly departs from their mental parameters, or that They can cancel you because you go out of your way, you can already imagine more or less what rung of thought the majority of society is on:

Why is all this so important? Precisely because the human mind, left to its own devices, pursues what is immediately easiest and simplest and most absent of uncertainty. The mind worships what is comfortable and what serves its selfish interests. At the same time, he naturally resists what is difficult to understand, what implies complexity, what requires penetrating the thoughts and difficulties of others, whether empathically or simply intellectually.

Whether as educators or ordinary people, we must treat thinking (quality thinking) as our top priority. When we learn together as developing thinkers, when we all seek to elevate our thinking to the next level, and then the next, we all benefit.

The professional and mental problems of postdoctoral researchers due to the pandemic

By portal-3

Los problemas profesionales y mentales de los investigadores postdoctorales debido a la pandemia

Six out of ten postdoctoral researchers they think the pandemic has worsened their career prospects, and one in four feel their supervisors have not done enough to support them during the pandemic.

Besides, 23% of respondents said they have sought help for anxiety or depression caused by their job, and another 26% would like that help but has not yet sought it.

Survey in 96 countries

These are the data that reflects a survey carried out by the magazine Nature to postdoc, already in a precarious and stressful situation.

Even, 51% of respondents in the latest survey have considered leaving active research due to work-related mental health issues.

The survey was conducted in June and July, and More than 7,600 people responded from 19 different disciplines. The sample, a self-selected group spread across 93 countries, is not completely representative globally, because the vast majority of respondents are in Europe and North America. All in all, the panorama that emerges is undoubtedly worrying.

Postdoctoral or postdoctoral research is academic or scientific research carried out by a person who has completed their doctoral studies, usually within the years following their degree, so, to cushion these effects, some institutions have carried out different strategies . For example, the US National Science Foundation (NSF) has extended project deadlines and ordered universities to continue paying the salaries of NSF-funded postdocs,although the investigation had to be suspended.

However, this situation will not be sustainable for long, as the costs are high and overall student mobility will be much lower than usual in the next academic year, so some institutions will lose a good fraction of their fee income.

We are in a deterministic universe where freedom does not exist: could accepting it be dangerous on a moral level?

By portal-3

Estamos en un universo determinista donde la libertad no existe: ¿aceptarlo podría ser peligroso a nivel moral?

Since everything around us is governed by inflexible laws, where there is a complex (and sometimes inextricable) chain of causes and effects, introducing free will is, from a scientific point of view, almost a fantasy.

But we continue to do it because accepting that everything is written, that all the fish is sold, that we will never be able to decide what to do, is incompatible with our vision of the world. To the point that accepting such a thing, that free will is a cognitive illusion, Could it lead us to more erratic moral behavior?.

Determinism VS freedom

Eliminating the notion of free will could undermine moral behavior, increasing dishonest behavior. In it present study, several attempts to replicate this hypothesis are reported. In a series of five studies, the relationship between indications against free will and immoral behavior was tested..

The main purpose of the study was to closely replicate the findings of Vohs and Schooler (2008) using the same manipulations and measures or very similar to those used in their original studies.

The efforts were largely unsuccessful, because manipulating beliefs about free will in a robust way is more difficult than has been implied in previous work, and the proposed link to immoral behavior may not be as consistent as the work suggests. former.

In other words: We are so programmed to believe in free will that pretending not to believe in it to see that immoral behavior increases is difficult..

For now, we can only speculate about it, as does the science fiction novelist Ted Chiang In one of the stories included in his new anthology, Exhalation, titled: What is expected of us. It describes how a large part of the population reacts when it is scientifically discovered, in an unquestionable way, that free will does not exist and everything is determined: adopting a akinetic mutism, a kind of deep apathy, because everything makes no sense.

That is to say, rather than acting badly, it seems that people simply do not act, which is why the text proposes perpetuating the collective deception of free will (although this is also somewhat determined):

And yet I know that since free will is an illusion, it is already predetermined who will fall into akinetic mutism and who will not. There is nothing to do about it; You cannot choose the effect that the Pronostic has on you. Some will succumb and others will not, and my sending this message will not change these proportions. So why am I sending it? Because I have no choice.

If you want to delve deeper into strong determinism, the possibility of free will, and the philosophical ramifications that all of this entails, you can do so in the following video:

Construction begins on gravity-driven energy storage system

By portal-3

Empieza la construcción de un sistema de almacenamiento de energía impulsado por la gravedad

The company Gravitricity It's going to start manipulating massive weights on an axle to store and deploy energy as needed. The axles will rise almost 1.6 kilometers in height and the weights will range between 500 and 5,000 tons. Huge winches will raise and lower the weights, and the axles will be pressurized to increase power production.

As the company says on your website: 'Our patented technology is based on a simple principle: raising and lowering a heavy weight to store and release energy.'

Gravitricity

According to those responsible for Gravitricity, maximum energy generation can reach between 1 and 20 megawatts, with continuous production of up to eight hours.

Costs are lower than current energy storage systems, such as lithium-ion battery-based solutions. Those responsible for Gravitricity also point out that, unlike battery systems, its storage mechanism can be charged and discharged several times a day without loss of performance for more than two decades.

The system's efficiency rate is 80 to 90 percent, and the system should last half a century.

The prototype system being developed by Gravitricity in Scotland, which will be completed and tested next year, will be limited to a 15 meter high shaft and a capacity of 250 kilowatts. Large-scale implementation will follow, as Gravitricity envisions utilizing abandoned coal mining pits globally for such energy storage plants.

Gravitricity's lead engineer, Miles Franklin, explains how the prototype will work:

Our demonstrator will use two 25 ton weights suspended by steel cables. In a test we will release the weights together to generate maximum power and verify our response speed. We estimate that we can go from zero to full power in less than a second, which can be extremely valuable in the frequency response and backup power markets.

The founder of Gravitricity is Peter Fraenkel, who invented the world's first tidal energy turbine. 30 years ago, the Fraenkel created a turbine to use the power of a river's current to bring water to Sudan, where he worked for a charitable organization. The civil war and lack of financing truncated their plans.

This is how the prognosis of cancer patients is worsening due to COVID-19

Así es cómo está empeorando el pronóstico de los enfermos de cáncer por culpa de la COVID-19

A study from the Centers for Disease Control and Prevention points out a drastic decrease in cancer screenings since the pandemic began.

The collateral effects of COVID-19 in this sense are clear: the delay in the diagnosis and treatment of cancer reduces the expectation of survival, As you can see in the following table.

Survival

According to This studio focused on the UK, this is the reduction in 10-year net survival per 3-month delay for 20 most common tumors:

Gr1

The study performed age-stratified and stage-stratified 10-year cancer survival estimates for patients in England, United Kingdom, for 20 common tumor types diagnosed in 2008-17 at age 30 or over from Public Health England.

Data were also used for cancer diagnoses made through the system's 2-week wait referral pathway in 2013-16. Cancer Waiting Times from NHS Digital. Hazard ratios (HRs) per day for cancer progression that were generated from observational studies of treatment delay were applied. The annual number of stage I-III cancers diagnosed through the 2-week wait pathway was quantified using age-specific and 2-week wait stage-specific breakdowns.

From these numbers, the total number of lives and life years lost in England due to delays per patient of 1 to 6 months was estimated.

It doesn't matter what language you speak: if you speak louder, you are more likely to infect others than by coughing or sneezing

By portal-3

No importa el idioma que hables: si lo haces más alto, es más probable que contagies a los demás que tosiendo o estornudando

As revealed A study published in Nature, the transmission of infectious agents through the air depends more on how loudly we speak than on coughs or sneezes. The effect is independent of language.

The researchers analyzed the broadcast in four languages: English, Spanish, Mandarin and Arabic.

Speech superspreaders

The hypotheses on the transmission of airborne infectious diseases have traditionally emphasized the role of coughs and sneezes, which are expiratory events that produce easily visible droplets and large quantities of particles too small to see with the naked eye.

However, it has long been known that normal speech also produces large quantities of particles that are too small to see with the naked eye, but large enough to carry a variety of transmissible respiratory pathogens.

The aforementioned study thus shows that the rate of particle emission during normal human speech is positively correlated with volume (amplitude) of vocalization, which varies from approximately 1 to 50 particles per second (0.06 to 3 particles per cm3) for low to high amplitudes, regardless of the language spoken (English, Spanish, Mandarin or Arabic). When you breathe, you are emitting particles from your saliva or respiratory fluid, from the trachea and from the lungs. If you talk, you emit 10 times more. If you scream or sing, 50 times more.

Furthermore, a small fraction of individuals behave as 'super-speech emitters', consistently releasing an order of magnitude more particles than their peers.

This can not only be explained by the phonic structures or the amplitude of speech, so the results also suggest that other unknown physiological factors, which vary dramatically between individuals, could affect the probability of transmission of respiratory infectious diseases and would also help explain the existence of superspreaders that are disproportionately responsible for outbreaks of airborne infectious diseases.

The wage gap that no one talks about: the beauty gap

By portal-3

La brecha salarial de la que nadie habla: el de la belleza

A recent study on worker attractiveness finds that there is a large 'beauty pay premium' for jobs that require significant interpersonal interaction, although not for jobs that primarily require working with data.

Welcome to the beauty pay gap. A gap, another one, that shows that the reasons, biases and heuristics that we use to value others at work are endless and that, possibly, Eliminating them would mean significantly reducing freedom..

Jungle of biases

This shows, once again, that employers discriminate. Another thing is that we consider that this discrimination is positive, negative, inevitable or avoidable, which already enters the political, almost philosophical, and also deontological field..

Geperut De Notre Dame

What seems evident is that discrimination is the only way to choose: faced with two identical resumes, one must choose something that inclines one towards one or another employee…which can even lead to in discriminating based on skin color: For example, if you open a restaurant with African cuisine, having black waiters may be preferable for the employer if they consider that it will increase their profits.

The time has passed when phrenologists and physiognomists inferred the characteristics of human beings from the protuberances of the skull or facial features. However, andThis has not eliminated our innate tendency to judge others by the type of face they have.. That's why villains usually look evil. That is why in the courts of law, lThose who have facial defects tend to be convicted more easily by popular juries.

Although an individual's personality is full of nuances and we will rarely be able to decipher it in a few personal interactions, we tend to consider the face as aa kind of Rosetta stone that will decode the entire inner universe of an unknown person.

All in all, this is a complex, protracted topic, full of sharp edges like the thorns of a rose like the one that guarded the Beast, so you can dive into its deep multifactorial consequences in the following video:

A new study estimates that orbiting Jupiter there would be about 600 moons (all larger than a kilometer)

By portal-3

Un nuevo estudio estima que orbitando a Júpiter habría unas 600 lunas (todas de más de un kilómetro)

A team of astronomers who have carefully studied archival data from 2010 from the Canada-France-Hawaii Telescope maintain that Jupiter not only has the 79 moons that have been detected so far, but many more: at least 600 irregular moons more than a kilometer in diameter.

That telescope has a powerful digital camera called MegaCam. It is a 340-megapixel wide-field imager that sees in optical and near-infrared. The authors will present their findings at the Virtual Europlanet 2020 Scientific Congress.

jovian moons

But what is the difference between regular and regular moons? If regular moons are formed by the accumulation of material in a disk (like planets) The irregular ones are objects captured by the planet's gravity, which on Jupiter is nothing to sneeze at.

Stacked Image Moon 900x469

That is, unlike Jupiter's largest moons, such as Io, Europa and Ganymede, these irregular moons were not formed by accumulating material in a disk.

Its capture may have been due to "gas entrainment, falling due to sudden mass growth, and three-body interactions."

Jupiter Moon Orbits 630x354

The team of astronomers found 52 objects in their images that they identified as irregular moons, and then they estimated the figure of 600 by simple extrapolation. The objects had magnitudes up to 25.7, and that corresponds to objects with diameters of approximately 800 meters. Of those 52, seven of the brightest were already known irregular moons.
