However, access to specimens is a major factor that influences the quality and quantity of research on reptiles. Why is Access to [...]ver notícia -
A paper-based sensor to detect pesticides in food quickly and cheaply
Publicado em 30 março 2023Researchers have developed a new paper-based sensor that can detect pesticides in food quickly and cheaply. This new technology has the potential to revolutionize the way we test for pesticides in our food supply. How Does the Paper-Based Sensor Work? The paper-based sensor works by using a special ink that changes color when it comes into contact with pesticides. The ink is printed onto a piece of paper, and then a small sample of the food is placed onto the paper. If the food contains [...]ver notícia -
Study: Post-bariatric surgery exercise modulates brain regions associated with regulation of food intake
Publicado em 23 março 2023A recent study published in the journal Obesity Surgery has found that post-bariatric surgery exercise can help regulate food intake by modulating brain regions associated with the regulation of food intake. The study involved 20 patients who had undergone bariatric surgery and were randomly assigned to either an exercise group or a control group. The exercise group participated in a 12-week exercise program, while the control group did not engage in any structured exercise. Before and [...]ver notícia -
Emerging deforestation frontier in southwestern Amazon sees increase in burnings
Publicado em 20 março 2023The southwestern Amazon region is known for its rich biodiversity and unique ecosystems. However, recent studies show that it is also becoming a hotspot for deforestation and burnings, threatening its fragile environment and contributing to climate change. According to Brazil's National Institute for Space Research (INPE), the first nine months of 2021 witnessed a 56% increase in burnings in the states of Rondônia, Acre, and Amazonas, compared to the same period in 2020. This [...]ver notícia -
Dry forests and savannas vital for Brazil's climate goals
Publicado em 15 março 2023Brazil has set ambitious climate goals to reduce greenhouse gas emissions, combat climate change, and preserve its unique biodiversity. To achieve these goals, it is critical that Brazil protects its dry forests and savannas. Dry forests and savannas cover around 40% of Brazil's land area and are home to a diverse range of plants and animals, many of which are found nowhere else in the world. These ecosystems also play a critical role in regulating the climate by storing carbon, [...]ver notícia -
News coverage highlights some threats to deer conservation but may mislead or omit key information

While it's true that deer populations are declining in some areas and facing challenges such as habitat loss and disease, some news reports may omit important information or present a misleading picture of the situation. One common misconception is that deer hunting is solely to blame for declining deer populations. While hunting can certainly [...]ver notícia -
Researchers use cellulose to develop slow-release fertilizer and a self-fertilizing propagation pot
Publicado em 17 outubro 2022October 17, 2022 by Karina Ninni, FAPESP A research team affiliated with the Laboratory of Polymeric Materials and Biosorbents at the Federal University of São Carlos (UFSCar) in Araras, São Paulo state, Brazil, has produced and is testing cellulose-based materials for enhanced-efficiency fertilizers to improve the supply of nutrients to crops and reduce the release of non-biodegradable chemicals into the ecosystem. The studies were led by Roselena Faez, a professor at the [...]ver notícia -
Specialty and standard coffee beans can be sorted using multispectral imaging and artificial intelligence
