In the selection of specialty coffees, those that score above 80 points in blind tests are free of physical and sensory defects. Greenish-colored beans are known to give the drink an astringent taste, which is described as harsh, pungent, and dry. These beans are therefore discarded, along with broken, black, burnt, pitted, or undersized beans. However, in a study published in the journal Food and Bioprocess Technology, researchers from the Federal University of Uberlândia (UFU) in [...]

One of the pillars of the Brazilian economy and one of the sectors responsible for the highest greenhouse gas emissions, beef production in Brazil, as it is currently practiced, emits more than twice the limit needed to meet international environmental targets. This is one of the conclusions of a study published in the journal Environmental Science and Pollution Research. The work includes an evaluation of projected emissions scenarios, along with an economic assessment. The researchers [...]

Unlike classical encryption, which relies on mathematical algorithms, quantum encryption assures security based on physical principles. Detection of espionage or interference is guaranteed by unavoidable alteration of the quantum states involved. Comparisons between the two systems yield impressive results. Classical supercomputers would currently take thousands of years to break strong encryption, but it will be possible to decipher the same codes in seconds with sufficiently powerful [...]

For thousands of years, plants have evolved in the presence of wildfires in the Cerrado, Brazil’s savanna-like biome. Scientists at São Paulo State University (UNESP) studied the effect of smoke on seed germination for 44 plant species typical of the Cerrado, as reported in an article published in Plant Ecology, where they stress that their findings could be used to optimize the restoration of degraded areas. The study was conducted by Ph.D. candidate Gabriel Schmidt Teixeira [...]
