Uma menina sapeca, inquieta e curiosa, filha de empreendedores.Na sua adolescência, ela decidiu ser farmacêutica porque encantava como as moléculas curavam as pessoas. Ainda na graduação, ela se deparou com a pesquisa e com a ciência, e ela tinha certeza que a vida dela iria tomar esse rumo. Durante 3s anos, realizou iniciação científica e sendo farmacêu ...

No meu primeiro ano do ensino médio, eu tive a oportunidade de ingressar no Instituto Federal de Educação, Ciência e T ...

Science and Scientific Method - Science provides narratives for better understanding the world, distinguished by the scientific method [5][6] - The scientific method involves observation, questioning, hypothesis formation, and testing to develop scientific theories [7] - A scientific theory must be testable and is subject to revision based on new observations and data [13][14] - Science advances through a cycle of technological and observational advancements that feed back into scientific progress [27] Examples of Scientific Progress - Edward Jenner's observation and experimentation led to the discovery of vaccination principles [9][10][11][12] - Albert Einstein initially believed in a static universe, but later recognized his error when evidence supported the expanding universe theory proposed by Lemaître and Friedman [17][18][19][20][21][22] Limitations and Biases in Science - Hypotheses can be influenced by the biases of their proposers, but the scientific method filters these biases [23] - Scientific understanding is limited by technological and observational capabilities at a given time [24][25][26] Pseudoscience and its Impact - Pseudoscience uses scientific terminology to lend credibility to practices lacking scientific basis [30] - Examples of pseudoscience include horoscopes and certain claims by "quantum" coaches or therapists [29][30] - The speaker urges the audience not to spread pseudoscience, denialism, or conspiracy theories [33] The Importance of Science - Contemporary life is deeply rooted in scientific processes [28][29] - Denying science is, in a way, denying our own existence [33] - Science is the best tool for building a more just, healthy, and sustainable society [34]
Ciência e conhecimento tradicional a favor da biodiversidade | Emiliano Ramalho | TEDxAmazônia

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]
Futuro das Mulheres na Ciência e Tecnologia: Derrubar barreiras | Marta Marques | TEDxTorres Vedras

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]
