[Música] Nós, seres humanos, somos uma espécie um tanto quanto distinta, sencientes, conscientes de nossa própria existência, sabedores de nossa própria morte. Essas características fazem quase que imperativa uma outra característica que essa sim deve ser única nos seres humanos, a capacidade de criar narrativas. Pensa comigo, o nosso nível de consciência, ele é tamanho que clama por respostas a algumas perguntas retóricas do tipo: "De onde viemos. para onde vamos.

Biodiversity & Conservation - 20% of the planet's biodiversity is in Brazil, most of which is in the Amazon, but 20% of the Amazon has already been lost [2] - Traditional conservation separated people from nature, but a new paradigm integrates people into conservation unit management for sustainable use of biodiversity [5] - Monitoring biodiversity is crucial, exemplified by the Pirarucu monitoring technology, which increased populations by over 400% in managed areas [6][9] - Combining scientific methods with traditional knowledge from indigenous communities is powerful for Amazon conservation [25] - Investment in ancestral knowledge and local Amazonian research is essential for solutions, as the solution for the Amazon lies within the Amazon [26] Technology & Monitoring - Current technologies effectively monitor the forest from above, but struggle to monitor what's inside the forest, including animals [10][12] - The Instituto Mamirauá developed technology using AI to monitor biodiversity in real-time, aiming for a system to monitor the entire Amazon [20] - The system integrates photo and audio capture, identifying species in real-time autonomously, forming the largest network of autonomous sensors in the Amazon [21] - This technology integrates with laser monitoring and satellite imagery, providing species presence data and models for prioritizing conservation areas, reducing information gathering time from months/years to hours [22] - The "Drop" technology allows remote deployment via drones, supporting territory surveillance by communities and indigenous peoples, generating alerts for invasions and species presence [23][24]

Gender Inequality in Science - The stereotype of a scientist is often a middle-aged man with a white coat and glasses, but this doesn't reflect the diversity within the field [3][4] - In 2018, women represented approximately 33% of the total number of researchers in the European Union, indicating a minority representation [10] - Women are underrepresented in leadership positions in science, hindering their career progression and access to funding [12][13] - A significant number of scientists have experienced gender-based violence [13] - Despite higher graduation rates among women in Portugal, this does not translate into equal career progression in science [14][15] - Women receive less funding than men due to biases in curriculum evaluation [16] - Societal norms, stereotypes, lack of role models, and the impact of motherhood contribute to the underrepresentation of women in science [18][19][20] Importance of Diversity in Science - Science needs diverse voices, including men, women, and those who don't fit into labels, to foster innovation and a culture that values diversity [21][28] - Collaboration, networking, and respecting ideas are crucial for scientific advancement, regardless of gender, origin, or appearance [28][29] Gender Differences in Disease and Treatment - Gender has a significant impact on how diseases manifest, develop, and are treated [22] - Cancer incidence varies between sexes, with breast cancer being more prevalent in women and prostate cancer in men [23] - Mortality rates are higher in men, highlighting the need for targeted therapies and personalized medicine [24] - Targeted therapies, such as monoclonal antibodies and peptides, aim to eliminate tumor cells while minimizing side effects [25][26]
