Disposal of food packaging is a major cause of environmental pollution worldwide. More than 350 million metric tons of plastic are produced every year, and 85 percent of the garbage dumped in the oceans is plastic, according to estimates. Brazil is the fourth-largest producer, accounting for some 11 million metric tons per year. To make matters worse, most plastic packaging is derived from non-renewables such as petroleum. Given all these drawbacks, reducing the use of fossil fuels to [...]

Between 118 and 138 million tons of organic waste are generated annually worldwide, with waste from the food production and distribution chain accounting for 100 million tons of the total. Only about 25 percent of all this biowaste is collected and recycled. The other 75 percent is simply thrown away, representing a huge loss of potential resources and major damage to the environment. These numbers are from a report published in 2018 by the European Environment Agency. Its statistics are the [...]

In 2019, history student Rodrigo Gomes found out on social media about a call for volunteers to take part in a scientific project relating to the ocean and conducted by the Federal University of São Paulo’s Institute of Marine Sciences (IMAR-UNIFESP) in Santos, on the coast of the state of São Paulo, Brazil. He signed up for the project, took workshops, and trained in the field. “I was very fortunate to have all that contact with professors and learned a great deal [...]

A team of scientists has discovered a new marmoset species in the Brazilian Amazon. Schneider’s marmoset (Mico schneideri), described in the latest issue of the journal Scientific Reports, is named after professor Horacio Schneider, a pioneer and major contributor to the research of diversity and evolution of monkeys. The discovery was made by a team of researchers led by Rodrigo Costa Araújo, currently an associate researcher at Museu Paraense Emílio Goeldi. Araújo [...]

More than 70% of plant species that produce flowers depend on birds to disperse their seeds. Birds feed on fruit from a wide array of different plants, and bird-plant interactions configure a welter of complex networks. A study conducted at the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil shows that the evolutionary stability of each bird species depends on the position it occupies in these networks, increasing in step with the number and centrality of [...]

In Brazil, researchers affiliated with the Center for Nuclear Energy in Agriculture (CENA) and the Luiz de Queiroz College of Agriculture (ESALQ), both part of the University of São Paulo (USP), have developed a methodology based on artificial intelligence to automate and streamline seed quality analysis, a process required by law and currently done manually by analysts accredited with the Ministry of Agriculture. The group used light-based technology like that deployed in plant and [...]

It is already possible to produce food with a 3D printer, potentially delivering products that suit consumer preferences regarding taste, texture, cost, convenience, and nutrition. In the near future, it will be possible to produce food with personalized shapes, textures, flavors, and colors considered attractive and healthy for children and the elderly, for example. A group of researchers at the University of São Paulo's Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil, [...]

The onset of any physical exercise program causes muscle pain that can hinder movements as simple as getting up from a sofa. With time and a little persistence, the muscles become accustomed to the effort, developing more strength and endurance. Researchers affiliated with Harvard University in the United States and the University of São Paulo (USP) in Brazil describe the cellular mediator that makes this adaptation to exercise possible in the journal Cell. The mediator is succinate, a [...]

Brazilian red propolis found in beehives along the coast and mangroves in the Northeast region contains two substances with anti-cancer properties. In laboratory tests, they considerably reduced the proliferation of ovarian, breast, and brain cancer cells. In a study published in the Journal of Natural Products, researchers at the Universities of São Paulo (USP) and Campinas (UNICAMP) report their discovery of the two anti-cancer substances as well as six novel polyphenols with [...]
