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.

Global animal populations have declined by an average of two-thirds in less than half a century.

By portal-3

Las poblaciones mundiales de animales han disminuido en promedio dos tercios en menos de medio siglo

According to him WWF Living Planet Report 2020 (World Wide Fund for Nature), Wild animal populations have fallen by two thirds since 1970. Specifically, 68% in global populations of mammals, birds, amphibians, reptiles and fish between 1970 and 2016.

Freshwater wildlife have also suffered a decline of 84%, the steepest average population decline in any biome, equivalent to 4% per year since 1970.

The principal cause

The main factor in this animal loss is due to our diet.: We need a lot of land to produce food, which results in habitat loss and degradation, including deforestation.

That is, to solve the problem, drastic measures must be taken, both in the way we eat and manage food, as well as invest more in the protection of certain environments.

The Living Planet Index (LPI), provided by the Zoological Society of London (ZSL) tracked almost 21,000 populations of more than 4,000 vertebrate species between 1970 and 2016. As Gun explains Tim Newbold, from the UCL Biodiversity and Environment Research Center (University College London):

Changing land use, whether for agriculture, energy, transport or housing, has a profound impact on biodiversity, as many plants and animals can no longer survive in an environment, and the remaining wild nature may not be large enough to support a species. This is now affecting the composition of plants and animals, as generalist species are better able to survive while more specialized species become extinct.

The future cost of pollution: around $100,000 per ton of carbon

By portal-3

El coste futuro de la contaminación: alrededor de 100.000 dólares por tonelada de carbono

Unlike the estimation of other social costs of releasing carbon dioxide into the atmosphere, one has been made that goes beyond the year 2100.

In this way, it is estimated that carbon dioxide emissions into the atmosphere will cost future generations $100,000 per ton, a thousand times more than what was calculated for our generation.

Generational costs

The study, carried out by two geoscientists and a philosopher from the University of Chicago, published in the journal Climatic Change, calculates the so-called “social cost of carbon”, a number intended to represent the value of all future damages to our generation in today's dollars.

AntarcticaThis image shows changes in the thickness of Antarctic land ice measured by two satellites, one that ran between 2003 and 2009 and another that began in 2018.

The calculations take into account the full magnitude of sea level rise, which reduces, among other things, cropland. The final costs are a thousand times higher than the normally calculated present value of those costs because climate change will persist a thousand times longer than our generation, according to one of the authors, David Archer, computational climate scientist:

What we wanted to achieve with this calculation is a better idea of the burden we are imposing on future generations. This is not intended to be a realistic estimate of the present value of costs, but is our attempt to try to put the enormous time scales into more understandable units. Most people are not geologists, and even for us it's really hard to think about how long the changes we're making now are going to last.

The authors emphasized that the model is not intended to be an exact measurement, but rather to help people visualize the future. The costs are also added assuming that there is no economic growth in the current world.

Because it is impossible to reliably predict humanity's long-term future, we had to make unrealistic simplifying assumptions, such as that humanity lives in a stable state with a planet's carrying capacity without changes in technology.

African Americans are more likely to die from colorectal cancer, and the system is to blame

By portal-3

Los afroamericanos tienen más probabilidades de morir de cáncer colorrectal, y la culpa es del sistema

Chadwick Boseman, who will play King T'Challa in the film Black Panther, died recently of colon cancer at age 43 after years of fighting.

A study conducted with 16,382 patients has found that African Americans are, in fact, less likely to receive life-saving medical care, such as chemotherapy, so they have 17% more likely to die from colon cancer than their white peers.

Poor medical care

The researchers of City of Hope National Medical Center in California analyzed data from 2000 to 2012 on California patients with colon cancer that has spread to the liver, comparing treatments, outcomes, and demographics such as race, age, sex, and concurrent health problems.

They found that black people are 10% less likely overall to receive life-saving colorectal cancer treatment. They are also 17% more likely to die than their white peers.

According to the research, this could be attributed to factors such as lower referral rate to cancer specialists, late detection of colorectal cancer metastases, and patient-reported barriers, including fear of cancer and its treatment, costs and burdens of transportation, and childcare during therapy.

That is to say, that we are not simply dealing with genetic or biological factors, but as a result of complex intersections of discrimination and inequality in employment, housing, stress and other chronic diseases, as well as reliable access to both preventive care and medical treatment.

Since 1993, we have prevented the extinction of at least 28 species of birds and mammals

By portal-3

Desde 1993, hemos evitado la extinción de al menos 28 especies de aves y mamíferos

The Puerto Rican Amazon Amazona vittata, Przewalski's horse Equus ferus, the alagoas Antwren Myrmotherula snowi, the Iberian lynx Lynx pardinus and the black mosquito Himantopus novaezelandiae They are some of the species that have become extinct in recent decades.

However, as published in A study in Conservation Letters, This has not happened thanks to our prevention and conservation actions.

From 21 to 32 bird extinctions

The research team, which includes experts from BirdLife International, Sapienza University of Rome, Italy, and the Zoological Society of London, among others, identified species of birds and mammals that were listed as threatened on the International Union for Conservation of Nature's Red List. Nature Conservation.

Specifically, since 1993, researchers have found that from 21 to 32 bird extinctions and from 7 to 16 mammal species. The findings are highly relevant to the United Nations Convention on Biological Diversity (CBD), which came into force in 1993.

21 bird species benefited from the control of invasive species, 20 from conservation in zoos and collections, and 19 from site protection. 14 mammal species benefited from the legislation and nine from the reintroduction and conservation of species in zoos and collections.

The findings also show that without conservation actions, extinction rates they would have been around 3 to 4 times larger. As explained Rike Bolam, from the University of Newcastle, lead author of the study:

It is encouraging that some of the species we studied have recovered very well. Therefore, our analyzes provide a surprisingly positive message that conservation has substantially reduced bird and mammal extinction rates. While extinctions have also occurred during the same time period, our work shows that it is possible to prevent extinctions.

Negotiations are currently underway to develop a new framework to address biodiversity loss by 2030.

Men are more emotionally open to women than to other men.

By portal-3

Los hombres se abren más emocionalmente a las mujeres que a otros hombres

Men's conversations with other men tend to focus on depersonalized topics, such as shared activities, politics, football, etc.

On the contrary, with women, men tend to reveal their emotions more frequently and report that relationships with women are more meaningful, intimate, satisfying and pleasant than relationships between men

Intimacy and sex

Men's concern about status differences has implications for their friendships, so they tend to be cautious about entering into very intimate relationships with other men where weaknesses or concerns are revealed: such information could one day be used against you.

As suggested in A study by Valerian J. Derlega, Bonnie Durham, Barbara Gockel, and David Sholis: If men do not reveal personal information, other people cannot understand, predict, or control their behavior.

Although men will reveal facts about themselves, They are much less willing than women to share emotions. They are particularly unlikely to share negative emotions that reveal vulnerability, such as depression, anxiety and fear, as suggested in this other study.

Men's conversations with other men tend to focus on shared activities or depersonalized topics, such as politics and sports. Compared to women, they are more likely to define intimacy with other men in terms of shared activities rather than shared emotional experiences.

However, when they are with women rather than men, men make more emotional disclosures.. Which could partially explain why '(1) men tend to fall in love more easily than women; (2) women tend to fall out of love more easily than men.'

Missing link in ape fossil record found in India

By portal-3

Se encuentra en la India un eslabón perdido en el registro fósil de los simios

Christopher C. Gilbert, from Arizona State University, has filled an important void in the fossil record of apes with the discovery of a 13 million year old fossil unearthed in northern India comes from a newly discovered ape, the oldest known ancestor of the modern gibbon.

The find was by chance, on a small hill in an area where a fossil primate jaw had been found the previous year.

Kapi ramnagarensis

The fossil, a complete lower molar, belongs to a previously unknown genus and species (Kapi ramnagarensis) and represents the first new species of fossil ape discovered at the famous Ramnagar fossil site, India, in almost a century.

Map Of Gibbon MigrationMap illustrating the location of Kapi (black star) in relation to modern (dark green) and historical (light green) populations of lesser apes and the approximate distribution of early fossil apes in East Africa (blue triangles). Green triangles mark the locations of previously discovered fossil gibbons. The new fossil is millions of years older than any previously known fossil gibbon and highlights its migration from Africa to Asia. Illustration by Luci Betti-Nash.

The molar was photographed and scanned by computed tomography (CT), and comparative samples of teeth from living and extinct apes were examined to highlight important similarities and differences in dental anatomy. According to Gilbert explains.:

From the shape and size of the molar, our initial assumption was that it might be from a gibbon ancestor, but that seemed too good to be true, given that the fossil record of lesser apes is virtually nonexistent. There are other primate species known during that time, and no gibbon fossils had been found anywhere near Ramnagar. So we knew we would have to do our homework to find out exactly what this little fossil was.

In addition to determining that the new ape represents the oldest known fossil gibbon, the age of the fossil, around 13 million years, is contemporary with known great ape fossils.
