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

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...

Brains on the move

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. Global plastic production was 2 million tons in 1950, and reached around 400 million tons in 2016. It is the... View Article

The horizons of science

Man’s arrival on the Moon captured the public imagination better than any other scientific or technological achievement in the modern era. The feat seemed so unattainable that, to this day, conspiracy theories abound that the entire event was faked by the US government in the midst of a space race against the Soviet Union. Believe...

From neural networks to artificial intelligence

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

The role of museums

Images of the Brazilian National Museum in flames shocked the world. The 200-year-old institution, based in a former imperial palace, was home to plants and animals collected during nineteenth-century expeditions throughout Brazil, mummies and minerals gathered by the Portuguese royal family, prehistoric fossils and meteorites, and artifacts of extinct indigenous peoples. A collection of inestimable... View Article

Lighting the way

In certain fields, innovative scientific discoveries are increasingly reliant on large and often multinational facilities. These projects are frequently the subject of controversy within (and outside) the scientific community due to the high costs involved, particularly in developing countries, but supporters argue that such investments are needed to stimulate qualitative advances in science. In December... View Article

Public health challenges

An article recently published in The New York Times (“Anti-Vaccine Activists Have Taken Vaccine Science Hostage,” August 5) warns that fear of being misinterpreted has caused vaccine researchers to avoid talking about potential negative aspects of their effectiveness and safety, even minimizing results that could indicate problems related to their use. Considering the recent rise... View Article

Amazing Amazonia

“The abundance of scientific literature on the Amazon reflects the physical geography of the region: it is amazing, highly unusual, and exceedingly disjointed. Any who dare study it carefully will, at the end of that attempt, get but a small way past the threshold of a wonderful world.” This is the diagnosis made almost 110... View Article

Algorithms, microchips, and the elite

Controversy at the dinner table

Food preservation and processing methods, perfected over thousands of years, are fundamental to our health and well-being. Preserving meat in salt allowed us to transport it over long distances, and pasteurizing milk eliminates harmful bacteria and increases its shelf life. But problems can arise when conservation is no longer the objective; when salt, sugar, and... View Article
