    Recentemente dois professores da Universidade de Michigan conseguiram desenvolver um processo de retirar ouro da água do mar. Tudo graças à Cupriavidus metallidurans, uma bactéria que geralmente é encontrada no solo, próximo a minas. Os pesquisadores criaram um dispositivo no qual essa bactéria é colocada em contato com o cloreto de ouro existente na água do mar. Essa bactéria, ao longo de uma semana, come o cloreto e excreta ouro. A mais provável reação química da excreção é

    O oxigênio é indispensável para a vida no planeta Terra. Com a evolução dos produtores de oxigênio, a Terra foi habitada por miríades de espécies aeróbicas. Porém, segundo estudos desenvolvidos desde a década de 50, o uso do O2 parece estar relacionado com o envelhecimento e a morte celular. Uma das evidências de ação e injúria oxidativas é que desenvolvemos, por evolução, a capacidade de eliminar o excesso de espécies reativas de oxigênio (EROS) que prejudicam nossas células. Assim, uma das formas de minimizar esses danos oxidativos celulares se dá pelo uso de enzimas antioxidantes presentes em nossas células. Dentre as opções a seguir, marque a que relaciona um tipo de enzima antioxidativa e sua ação para diminuir as consequências das EROS.

          Hundreds of studies have assessed leadership styles, mainly by having employees report on how their managers typically behave. Researchers have also collected information on how effective managers are. After large numbers of such studies became available, reviewers aggregated them quantitatively to discover what kinds of leadership are effective.

          One conclusion that has emerged based on the research of the past 30 years is that a hybrid style known as transformational leadership is highly effective in most contemporary organizational contexts.

          A transformational leader acts as an inspirational role model, motivates others to go beyond the confines of their job descriptions, encourages creativity and innovation, fosters good human relationships, and develops the skills of followers. This type of leadership is effective because it fosters strong interpersonal bonds based on a leader’s charisma and consideration of others. These bonds enable leaders to promote high-quality performance by encouraging workers rather than threatening them, thus motivating them to exceed basic expectations.

          By bringing out the best in others, transformational leaders enhance the performance of groups and organizations.

          Transformational leadership is androgynous because it incorporates culturally masculine and feminine behaviors. This androgynous mixing of the masculine and feminine means that skill in this contemporary way of leading does not necessarily come naturally. It may require some effort and thought.

          Men often have to work on their social skills and women on being assertive enough to inspire others. It is nonetheless clear that both women and men can adapt to the demands of leadership in the transformational mode.

          One of the surprises of research on transformational leadership is that female managers are somewhat more transformational than male managers. In particular, they exceed men in their attention to human relationships. Also, in delivering incentives, women lean toward a more positive, reward-based approach and men toward a more negative and less effective, threat-based approach. In these respects, women appear to be better leaders than men, despite the double standard that can close women out of these roles.

          Why are women leaders more transformational when they are less likely to become leaders in the first place? One reason is that the double standard that slows women’s rise would work against mediocre women while allowing mediocre men to rise. As a consequence, the women who attain leadership roles really are better than the men on average.

          It is also true women generally avoid more domineering, “command and control” behavior because of the backlash they receive if they lead in this way. Men can often get away with autocratic behavior that is roundly disliked in women. Ironically, this backlash against domineering women may foster good leadership because the androgynous middle ground is more likely to bring success. Leaders gain less from ordering others about than from forming teams of smart, motivated collaborators who together figure out how to solve problems and get work done.

    A anemia falciforme decorre de uma mutação específica no gene da beta-globina que é um tipo de hemoglobina denominada de hemoglobina S. Os indivíduos que possuem a hemoglobina S apresentam quadros periódicos de febre e dor, pelo fato de a hemoglobina S formar longos cristais quando as concentrações de oxigênio estão abaixo do normal. Então, essa cristalização interfere na estrutura da membrana celular, provocando o rompimento da célula. Adicionalmente, estas células que sofreram lise podem causar o entupimento das veias, levando o indivíduo à morte. Abaixo estão os dois pedaços do gene da beta globina. A primeira sequência corresponde ao DNA de um indivíduo normal; a segunda sequência corresponde ao DNA de um indivíduo com anemia falciforme.
