Cientistas Recriam Pigmento Azul de 5.000 Anos

6 days ago | forbes.com.br | Eva Amsen

Os antigos egípcios usavam pigmentos para criar tinturas, mas a origem de uma tonalidade específica de azul se perdeu com o tempo. Esse corante era encontrado regularmente em artefatos do Egito Antigo e continuou sendo usado pelos romanos. Depois disso, porém, seu uso foi diminuindo gradualmente até que ninguém mais soubesse como produzi-lo. Agora, pesquisadores da Universidade Estadual de Washington conseguiram recriar o tom.

Ancient Egyptians used pigments to create dyes and paints, but the origin of one blue pigment was lost to time. This dye was regularly found on artefacts from ancient Egypt, and still used by the Romans. After that, though, it was gradually used less and less until nobody remembered how to make it. But now, researchers from Washington State University have recreated this blue pigment. Researchers Travis Olds and Lisa Haney from the Carnegie Museum examine an ancient sarcophagus that ...
Drug Use Affects How People Feel The Groove In Music

A new study found that people who regularly used cocaine or heroin in the past experience music in a different way. This might seem strange, but it all has to do with dopamine. Part of what makes music enjoyable is the “groove” – the urge to move to the music. People experience this feeling with rhythms that are somewhat predictable, but not too predictable. When we listen to music with a somewhat predictable rhythm, we can anticipate what’s coming.

People have been using pigments to create art for centuries. But not all pigments are the same. Some change color over time, some are made of rare materials that are difficult to find, and some might be poisonous. Understanding these pigments is important for art historians and conservators who handle and repair old art, and now researchers are turning their attention to South Asian pigments. Over the years, chemists have learned a lot about the types of pigments used in Western art.

In two separate studies, researchers learned more about the way that our brains respond to music. One study found that brain neurons synchronize with musical rhythms, while the other showed how favorite music triggers a chemical pleasure signal in the brain.

A tiny snail was recently named after painter Pablo Picasso. It’s one of many species named after celebrities or artists, but some researchers question whether species should be named after people at all. How do you name a snail? That’s a question that several mollusk researchers tried to answer when they re-evaluated the names of hundreds of snail species from Southeast Asia.

Sea lion Ronan first made the news in 2013, when researchers revealed that Ronan had the unusual ability to bob her head to the beat. Twelve years later, Ronan still loves a good beat. A new study about her unusual musical ability describes how she has no trouble keeping up with humans in a rhythm exercise. The human volunteers in the study were ten undergraduate students at the University of California, Santa Cruz.
Fractal Math Describes How Realistic Trees Look In Art

Feb 28, 2025 | forbes.com | Eva Amsen

What makes a tree a tree? Or rather, why can we recognize trees in even quite abstract depictions when they are so varied in nature? Researchers have found a clue in the branches, and used math to describe how the way we see branches in nature and art contributes to our recognition of trees. "We've come up with something universal here that kind of applies to all trees in art and in nature," Mitchell Newberry told the University of Michigan.
