A pesquisadora chegou a cortar \u00e1guas vivas da esp\u00e9cie, ferv\u00ea-las, deix\u00e1-las passar fome, inserir sal em seu tanque de \u00e1gua e at\u00e9 mesmo jog\u00e1-las em \u00e1gua doce.<\/p>\n<p>Em vez de morrerem, contudo, essas pequenas criaturas se transformaram em bolas de c\u00e9lula, sem similaridade com seu formato natural, e depois de tr\u00eas dias ressurgiram no seu estado inicial da vida.<\/p>\n<p>As<em> Turritopsis dohrnii<\/em> foram descobertas em 1992 por um cientista italiano que esqueceu-se de aliment\u00e1-las por um fim de semana. Ao retornar ele acreditava que as encontraria mortas, mas deparou-se com \u00e1guas-vivas ainda mais jovens no recipiente.<\/p>\n<p data-intext-processed=\"true\">De acordo com o que disse o oncologista pediatra Michael Koldobskiy, f\u00edsico e cientista da Universidade Johns Hopkins, \u00e0 BBC News, estudar as \u201c\u00e1guas-vivas imortais\u201d pode ser uma chave para a biologia regenerativa.<\/p>\n<p>\u2013 O santo graal deste tipo de desenvolvimento, eu acho, seria a biologia regenerativa: tentar reverter a degenera\u00e7\u00e3o ou degrada\u00e7\u00e3o relativa ao envelhecimento. Estamos muito longe de aproveitar isso para benef\u00edcio humano, mas acredito que conhecer os organismos que evolu\u00edram estes processos milh\u00f5es de anos atr\u00e1s possivelmente poder\u00e1 valer a pena \u2013 declarou.<\/p>\n<\/section>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u00c1gua viva (Imagem ilustrativa) Foto: ChatGPT \/ OpenAI Turritopsis dohrnii \u00e9 uma esp\u00e9cie importante para a biologia regenerativa Uma esp\u00e9cie curiosa de \u00e1gua viva pode ajudar os cientistas a avan\u00e7arem em pesquisas sobre o tema que mais aflige a humanidade: desafiar a morte.
