Numbers

With the second most COVID-19 deaths in the world, Brazil has already surpassed 200,000 victims of the disease. The figure could be much lower if preventive measures proven to be effective were more widely followed, such as social distancing, the use of masks, and strict hygiene practices. It is equally undeniable that the number could... View Article

Take care

Surgeon Angelita Habr-Gama has dedicated her career to developing treatment strategies that aim to prevent rectal cancer patients from needing to have the organ removed. The results of research carried out by her group since the 1990s were published last month, showing that patients need not undergo a proctocolectomy if the tumor regresses completely after...

Encouraging prospects

In February of this year, when we were putting together the March issue, the first official record of SARS-CoV-2 infection in Brazil was confirmed. We had no idea what the future might bring. Our first article on the topic, “The Novel Coronavirus in Brazil,” reported on the disease’s arrival and described the other types of... View Article

The Pantanal’s turn

The Pantanal is one of the best-preserved biomes in Brazil. As of 2019, 84% of its native vegetation had been maintained. It’s landscape is shaped by heavy rainfall and river floods, which leave much of the land flooded for months, as well as droughts that result in sporadic fires. The fires that devastated 27% of...

Legal subjects

The idea that children are individuals who deserve the same rights as adults, as well as other specific rights based on their inherent vulnerability, is a recent one. Previously seen as belonging to the family or the State, the notion that they deserve particular attention grew in popularity as we learned more about childhood development,... View Article

An all-inclusive illness

When the first reports emerged of a new disease in China at the turn of the year, it was described as a “pneumonia of unknown cause.” A few months later, with 25 million cases and 900,000 deaths worldwide, COVID-19 is known to be a more complex and widespread disease than previously thought. Immunologist Anthony Fauci,... View Article

The plague and the pain

It is no surprise that pandemics have a significant impact on the population’s mental health. The fear of contagion and death, the immediate impact of an economic downturn, the stress of confinement, the burden of having to take on  tasks that used to be shared by multiple people, and worrying about the future have all...

The challenge of immunization

Less than four months after China notified the WHO that it had identified a cluster of pneumonia cases “of unknown cause,” potential vaccines for the novel coronavirus had already begun human testing. One of the first companies to start phase 1 clinical trials (in humans) was Chinese biopharmaceutical firm Sinovac Biotech, with which the Butantan... View Article

Crucial numbers

Little is known about viruses. Existing on the boundary between the living and the nonliving, they are found in all environments where there is life. Their effects on living beings can be beneficial, harmless, or capable of triggering devastating epidemics, such as Ebola, Zika, and now, SARS-CoV-2. Although the number of species is estimated in...

Journalism during a pandemic

On March 20, the Pesquisa FAPESP offices closed and the team began working remotely. The April issue was completed in the midst of a rush to establish new working processes involving videoconferences, content-sharing platforms, and cloud storage. The May edition, meanwhile, was planned and executed from a distance, with only the journal’s photographer, Léo Ramos... View Article

A challenge for science

In May 1919, when the H1N1 pandemic known as the Spanish flu was slowing down, the journal Science published an article titled “The Lessons of the Pandemic.” In the article, American sanitation engineer and epidemiologist George A. Soper wrote: “The most astonishing thing about the pandemic was the complete mystery which surrounded it. Nobody seemed... View Article

Women and Science

Modern science and its remarkable advances are closely associated with the ideas and research of men. Although this perception is not entirely accurate, it is also not incorrect. Like all human activity, science is a part of our current social structure, which is undoubtedly based on a male perspective. Londa Schiebinger, a professor of the... View Article

DNA tampering

The idea of manipulating DNA to modify the human body is slowly becoming a reality. Researchers from all over the world, including Brazil, are working on methods that could effectively eliminate or alleviate certain diseases. What these scientists want is to silence, alter, or replace the genes that cause problems. Last year, Chinese scientists announced... View Article

Pesquisa Fapesp, 20 years

n 1963, a report by the Royal Society on the emigration of scientists sparked a public debate over so-called brain drain. Half a century later, international mobility among scientists is still an object of debate fueled by reports and studies. Initially restricted to people with a background in science and technology, the term currently covers... View Article

Calcium for tomatoes

Agriculture’s advance in Brazil is directly linked to scientific and technological research in the sector. The Agronomic Institute of Campinas was created in 1887, and the country’s first master’s thesis defended in 1961 at what is now the Federal University of Viçosa, was in the field of agronomic engineering, on the effects of irrigation and...

Evangelicalism and politics

In 1872, the year of the first Brazilian census, almost the entire population of the country defined themselves as Catholic (99.7%). One hundred years later, the proportion had changed, but only slightly, to 91.8% in 1970. Since then, official statistics show, the decline has accelerated: in 1991, the total was 83.3%, and in 2010 it... View Article

Challenges in the Amazon

The debate on the Amazon’s future depends largely on how exactly we define development. Since the 1970s, several governmental initiatives—as well as many private, often illegal ones—have focused on occupying the territory for farming and mining activities, as well as using its rivers to generate electricity, even if uncontrolled logging is involved. Northern Brazil is... View Article

Journalism for science

In October 1999, the Notícias FAPESP newsletter became the Pesquisa FAPESP journal, expanding the mission for scientific dissemination begun four years earlier by the foundation from which the publication gets its name. Two decades later, the need and desire to inform the public about science produced in Brazil and in the state of São Paulo... View Article

Fortune and chance

Science evolves in a nonlinear manner. Subject to mishaps and chance, its path is much more lively and interesting than one might presume. Frequently, there is a good story behind important discoveries. One of these stories happened one hundred years ago and had Brazil as its stage. In 1919, Albert Einstein was not yet the...

In 1963, a report on the emigration of scientists by the British scientific academy The Royal Society triggered what would come to be known as the brain drain debate. The origin of the term is attributed to then Minister of Science Lord Hailsham, who accused the USA of “parasitizing British brains.” Half a century later,... View Article

Too much plastic

Versatility is one of the many useful characteristics of plastic, which can be used in a range of applications in place of glass, wood, paper, metal, and natural fabrics, making it ubiquitous in modern society.

In the early 1990s, researchers from São Paulo submitted research proposals to FAPESP on artificial neural networks, a relatively unknown field at the time, in which computer systems simulate the human central nervous system. The objective is to develop algorithms that recognize patterns, allowing the machine to “learn.” Artificial intelligence (AI) first emerged in the... View Article

Constitution, 30

A constitution is the maximum applicable legal framework of a state; the set of its fundamental principles. It confers powers and establishes their limits. Constitutions vary in form and content depending on the history and traditions of the nation, and they are often replaced at times of significant political change. Brazil is no exception: the...
