A Dynamic Universe

The evolution of science is much less linear and predictable, as well as more susceptible to mistakes and chance, than it might first appear. There are often interesting stories behind important discoveries that despite now seeming irrefutable, may have been controversial at the time. One such case occurred 100 years ago, and a Brazilian scientist... View Article

Complex mechanisms

Publicly funded education in Brazil is a complex institutional system. The 1988 Constitution states that the process should be jointly funded and managed by all three levels of government: municipal, state, and federal.

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

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...

The role of museums

Images of the Brazilian National Museum in flames shocked the world.

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

In December, British newspaper The Economist published excerpts from an article based on weekly news reports written by an artificial intelligence program. The result demonstrated both the power and limitations of machine learning: the text imitated a journalistic writing style and mentioned topics often covered by the newspaper, using proper and correct grammar—but it did...

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
