A study conducted at the Brazilian Center for Research in Energy and Materials (CNPEM) has discovered that three strains of Pseudomonas bacteria can inhibit growth, and even cause the death, of the fungus responsible for pineapple sett rot, a disease that attacks sugarcane, especially in the planting season. The results are reported in an article published in Environmental Microbiology, a journal of the United Kingdom’s Society for Applied Microbiology, and could serve as a basis for [...]

Brazilian researchers have analyzed the mechanisms by which estuarine plants absorb iron, and used their findings to recommend a promising phytoremediation technique for the rehabilitation of water and soil contaminated by environmental disasters such as the 2015 collapse of the Fundão iron mine tailings dam in Mariana, Minas Gerais state (Southeast Brazil). An article on the study is published in the Journal of Hazardous Materials. he researchers conclude that Typha domingensis, [...]

Several natural disasters have afflicted various parts of Brazil since 2022 began, from deadly flooding and mudslides due to abnormally heavy rain in the states of Minas Gerais, Bahia, Rio de Janeiro and São Paulo, to severe drought in Rio Grande do Sul state. However, only 6.1% of its 5,568 municipalities have plans of any kind to mitigate the risk and impact of such disasters, according to a survey by IBGE, the national census and statistics bureau. An article published in the [...]

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% 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 produce [...]

Electromagnetic (EM) waves and gravitational waves are the only available means to study the Universe on a large scale. For millennia, only the former could be used, in naked-eye astronomical observations by the ancients based on the reception of visible light, or present-day super telescopes operating in various bands of the EM spectrum, from radio waves to gamma rays. Gravitational effects can be inferred from the relative movements of celestial bodies. The first direct measurement of [...]

A study conducted by researchers affiliated with São Paulo State University (UNESP) in Brazil shows that large mammals have a major impact on plant diversity, primary productivity and biomass in the understory of Neotropical forests. Species like the lowland tapir (Tapirus terrestris) and white-lipped peccary (Tayassu peccari) help keep an ecological balance in areas such as the Atlantic Rainforest with different levels of productivity, while also influencing the spatial structure of [...]

A study of the management plans for 118 conservation units in Brazil shows that 60% use unsuitable methods to detect the presence of deer, and that 38% do not even describe the method used. Conservation of these animals may be endangered as a result. Eight deer species occur in Brazil; three are red-listed as “vulnerable” by IUCN. Management plans prescribe the governance and technical aspects of the administration of protected areas in Brazil. The protected areas analyzed in the [...]

The rhythms of activity in all biological organisms, both plants and animals, are closely linked to the gravitational tides created by the orbital mechanics of the Sun-Earth-Moon system. This truth has been somewhat neglected by scientific research but is foregrounded in a study by Cristiano de Mello Gallep at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, and Daniel Robert at the University of Bristol in the United Kingdom. An article on the study is [...]

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% of all this biowaste is collected and recycled. The other 75% 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 most recent [...]
