According to psychologists from the University of California, Los Angeles, individuals who often seek snacks shortly after consuming a satisfying meal may possess hyperactive food-seeking neurons rather than an excessive appetite.   The team's findings shed light on how impulses to eat, regardless of hunger, can be triggered by a specific brain region rather than traditional stomach hunger cues. This discovery could potentially revolutionize our understanding of eating disorders, [...]

According to a study, the Rio Grande Rise undersea volcanic plateau could have been a tropical island roughly 45 million years ago. Signs of Dry Land The seafloor surrounding the Rio Grande Rise was the subject of exploration by Brazilian and British scientists in 2018. Back then, the specialists were able to notice some rocks that looked like they were from dry land. As they watched the footage taken by their remotely operated submersible around 650 meters below the surface, they were [...]

Glitter, widely used in apparel, cosmetics, and festive decorations, presents an emerging environmental threat. Despite its association with fun, new research reveals its dark side, as glitter particles reduce sunlight in water bodies, potentially harming aquatic plants. Unfortunately, glitter is not filtered by wastewater treatment, contributing to environmental pollution. The study, titled "Interference of glitter with the photosynthetic rates of a submerged macrophyte, Egeria [...]

The Amazon Rainforest, the largest rainforest in the world, is at risk of collapse. Researchers warn that it is approaching its tipping point and could happen in three decades. Amazon Rainforest at Risk of Collapse A new study learned that nearly half of the Amazon rainforest is at risk of collapse. Part of the reason is the "unprecedented stress" and a combination of climate change-related drivers like deforestation and global warming, to name a few. After analyzing data for [...]

Nanodiamonds have emerged as promising applications for semiconductors and tool surface modification. Recent advancements in nanotechnology have enabled researchers to embed these materials within polymer microstructures, opening up possibilities for enhanced quantum computing and biological studies.   Limitations in Diamond Structures Diamond is the only gem composed of a single element, carbon, surrounded by other carbon atoms linked together by covalent bonds. It also has both [...]

Aviation is considered one of the most significant contributors to carbon dioxide emissions, and reducing its impact on the environment is achieved by using sustainable alternatives to traditional fossil fuels. Biofuels produced from plant oils have been explored as a potential alternative, but they also come with an expensive and inefficient production process. Renewable Hydrocarbons for Aviation Scientists from the Brazilian National Center for Research in Energy and Materials (CNPEM) [...]

The volcanic outcrop Trindade Island is just one of the few remote places on Earth. It would take about three to four days by boat from the coast of Brazil to reach the place. So, geologist Fernanda Avelar Santos from the Federal University of Parana was shocked when she found an alarming indicator of human activities on the otherwise pristine landscape of the island. She saw "plastic rocks" or pebbles created from the abundance of plastic waste floating in the water. Discovery [...]

While the theory of evolution has been known to long clash with religion, a recent study reveals that religion is not the primary reason why schools reject evolution. According to SciTechDaily, a survey that covered 5,500 Italian and Brazilian students, from ages 14 to 16, revealed that social perceptions of science, nationality, and household income were more influential factors compared to religion. The findings of the study were included in the PLOS ONE publication. As part of the [...]

According to a recent study that was published in the journal Nutrition, supplementing one's diet with the amino acid taurine might be a feasible solution to the aging problem. Study and Findings Twenty-four female volunteers between the ages of 55 and 70 participated in the study at the University of Sao Paulo (USP). The participants were divided into two groups randomly. For 16 weeks, one group took three 500 mg taurine pills daily (1.5 g per day). The pills given to the opposing group [...]
