Some formula milk has twice as much sugar per serving as a glass of soda, according to one new research. But perhaps most surprising is the fact that there are very few regulations to control sugar content and ensure that consumers are well informed.
Baby formula, formula milk or infant formula is an artificial substitute for breast milk. It is usually produced from cow's milk.
Breast milk and sugar
Breast milk is the recommended source of nutrition for babies, especially during the first six months of life. Although it's sweet, sugar is mainly lactose and the content is specific to the baby's needs.
On the contrary, infant formula milk contains added sugars, such as corn syrup, which are added during production and are not found in breast milk.
This is harmful to babies because high consumption of added sugars can contribute to tooth decay, poor diet and encourage obesity.
In the aforementioned study, the sugar content of 212 infant formula dairy products available on the market aimed at babies under three years of age. The products were sold in supermarkets in 11 countries.
The findings revealed that more than half of the products contained more than 5g of sugar per 100ml. In many cases, the sugar content was more than 7.5 g per 100 ml, which exceeds the levels recommended by the European Parliament for infants.
One more reason to opt for breastmilk, that offers important benefits to the baby when you get sick and helps you recover sooner. Without counting that helps stop climate change and represents a saving of more than 100 kg of CO2 per baby.

According to a new numerical model of biogeochemistry and climate, developed by researchers at the Georgia Institute of Technology, Earth will maintain its oxygen-rich atmosphere for a billion years, before rapid deoxygenation makes the atmosphere reminiscent of early Earth.
The study, published in Nature, has important ramifications not only for the future of Earth's biosphere, but also for the search for life on Earth-like planets.
Stochastic approach
Oxygen (and the photochemical byproduct, ozone) is the most accepted biosignature for the search for life on exoplanets, and, from the looks of it, the oxygen-rich atmosphere might only be possible during 20-30% of the entire history of Earth as an inhabited planet.
The atmosphere after the major deoxygenation is characterized by high methane, low levels of CO2, and no ozone layer. The Earth system will likely be a world of anaerobic life forms.
Given that the modeling of the future evolution of the Earth harbors many uncertainties in the geological and biological evolutions, for the modeling of the future evolution of the Earth adopted a stochastic approach, which allows researchers to obtain a probabilistic assessment of the lifetime of an oxygenated atmosphere.
As explained Kazumi Ozaki, assistant professor at Toho University and lead author of the research:
For many years, the lifespan of Earth's biosphere has been debated based on scientific knowledge about the sun's constant brightness and the global carbonate-silicate geochemical cycle. One of the corollaries of such a theoretical framework is a continued decline in atmospheric CO2 levels and global warming on geological time scales. In fact, it is generally thought that Earth's biosphere will come to an end within the next 2 billion years due to a combination of overheating and a shortage of CO2 for photosynthesis. If true, it can be expected that atmospheric O2 levels will also eventually decrease in the distant future. However, it is unclear exactly when and how this will occur.

As suggested by this new study, still preprint, people evaluate moderate political opinions more negatively compared to extreme ones.
People who deviate from group norms pose problems for their ingroup, but not all forms of deviation are equivalent.
Four different experiments
The study was divided into four experiments. Participants thought that both Democrats (Experiment 1) and Republicans (Experiment 2) would view moderate political candidates more negatively (e.g., less loyal, less principled, more likely to defect) than extreme candidates. Furthermore, these relatively negative evaluations of moderates extended to rank-and-file members of the Democratic (Experiment 3) and Republican (Experiment 4) parties.
These findings suggest that people intuitively understand subjective group dynamics, and when applied to politics, this understanding can have important consequences for how people with moderate and extreme beliefs engage in political discourse.
The underlying point, then, is that people who deviate from the group's prescriptive norms can harm their group by blurring perceptions of consensus, thereby eroding the legitimacy of a group's position.
Without a doubt, another proof of the tendency to affiliate with the most extreme, compared to the most moderate. And how democracy is affected by it, in addition to the fact that politicians also take advantage, becoming radicalized in their speeches, especially using demagoguery and populism.
That is why, perhaps, in the cradle of democracy, in fact, a machine was used to choose elected officials because one could not trust the whims of the administrators: the klerotherion It was this device, used in the polis during the period of Athenian democracy, to randomly select the citizens who would participate in the majority of state positions.

Not only can we find structural gaps in the argumentative edifice of feminism: with a little scratching we can discover that this edifice suffers from aluminosis. We are talking, naturally, about dominant feminism, the one that is most fashionable, the one that spreads like wildfire on social networks and among the demagogic proposals of the various political formations. A crude, simple and superficial feminism that, however, has managed to colonize part of the Academy.
That is why books like this, truly feminist, are necessary, because the best way to be feminist is to strengthen the concept through criticism and the continuous extraction of impurities. Books like Dismantling hegemonic feminism, written in several hands by experts from each of the fields covered.
The lies that are repeated the most
With a prologue from the economist Maria Blanco, Dismantling hegemonic feminism It is a kaleidoscope of voices that make use of current academic literature to debunk the most repeated lies of mainstream feminism, usually a feminism that is more misandric, retrograde and even sexist than is usually admitted.
Thus, we find chapters to conceptually clarify the term feminism, written by Irune Ariño, at the time coordinator of the book. Also Francisco Capella is dedicated to clarifying the science underlying sexual differences. Santiago Calvo addresses economic inequality and discrimination (and the famous glass ceiling).
Dismantling Hegemonic Feminism
Marina de la Torre delves into the meta-meaning of feminism, and Cuca Casado, of which you can see below an extensive interview that I conducted regarding the publication of this book, focuses on all the errors that exist around gender violence:
Are the roles adopted by women and men determined by their biology? Do women earn less than men for doing the same work? Do women have the same chances of reaching senior management positions as men? Should women be able to offer their sexual services in exchange for financial compensation? Is machismo the main cause of intimate partner violence? What rhetorical strategies does mainstream feminism use to expand its message?

The China National Space Administration released a list in January of 10 selections for the name of China's first Mars rover following a global naming campaign that began in late July 2020.
have now been selected three of them, after domestic and foreign Internet users were invited to vote for 10 candidates from January 20 to February 28. Are the following.
The three selected
China launched Tianwen-1 on July 23, 2020. The spacecraft, which consists of an orbiter, a lander and a rover, entered the Mars parking orbit after performing an orbital maneuver on February 24. The rover is expected to descend to the Martian surface in May or June.
In order of votes, from highest to lowest, these were the finalists:
- Zhurong: is a god of fire in ancient Chinese mythology. He lived in a palace on Mount Kunlun and taught humanity how to use the fire that Suiren had created.
- Nezha: a beloved Chinese mythological figure.
- Hongyi: means having a broad and strong mind in Chinese.

Evidenced by a growth in brain volume, our higher cognitive abilities developed because we hunted and we extinct the megafauna, according to a new study from Tel Aviv University.
This would occur about two million years ago, until the arrival of agriculture, about 10,000 years ago. The reason: we had to develop our brains to hunt smaller animals.
Megafauna in decline
The megafauna They are "giant", "very large" or "big" animals. The term is especially associated in current scientific literature with the megafauna of the late Pleistocene and Holocene that have been becoming extinct in a process known as Quaternary mass extinction.
In Africa, 2.6 million years ago, when humans emerged, the average size of land mammals was close to 500 kg. But then, just when the agricultural revolution began, that figure had been reduced by more than 90%, up to several tens of kilos.
For the sake of getting calories, well, Humans were forced to hunt smaller, faster animals., which required greater cognitive abilities, more cunning, an evolutionary process that required a greater volume of the human brain and then led to the development of language that allowed humans to exchange information to find prey and collaborate to hunt them. More sophisticated hunting tools were also required, that is, greater intelligence to develop them.
As it explains Miki Ben-Dor, from the Department of Archeology and author of the study:
As the size of animals continued to decrease, the invention of the bow and arrow and the domestication of dogs allowed for more efficient hunting of medium and small animals. until these populations also decreased. Towards the end of the Stone Age, when animals became even smaller, humans had to put more energy into hunting than they could recover.
That's when the Agricultural revolution, which involved the domestication of both animals and plants, and which brought with it other side effects (many of which were negative).
