Hello everyone! I'm a native Brazilian-Portuguese speaker, and I'd be happy to help someone with their Portuguese. My current priority is to improve my English, so an English-Portuguese exchange is ideal, especially in English English (UK). However, I am a beginner in Russian and intermediate in Spanish. So, I'm also open to some language exchange for those languages.

A motivational poem The road of prickles "It'll be a long road, getting from here to there. Where there're roses, there may be prickles, beware! Hurdles are the pavement of every worthy path. Marvels await for the brave ones who face the fight. Keep on course, till the end of this warpath. And your reward will be right."

Sci-fi story - part I - Title: The cursed snog It is late at night and some researchers from the Royal London Hospital are still working in their lab. Pipetting and spinning tubes, analysing data and formulating new hypotheses. All of a sudden, one of them turned on a computer and started a video recording. “Alright, camera is now recording! There we go.” The woman muttered while she was adjusting the camera position. “My name is Doctor Scott, I’m a molecular oncologist specialised in oncogenic viruses”. After taking a deep breath, she went on. “I have spent the last two years of my life trying to find out the cause of the called “Pandora’s plague”, as you probably know, that’s a weird kind of melanoma that has spread out in different populations around the world. Throughout the years I had never seen anything like that. It’s an amelanic aggressive and highly metastatic cancer, which kills their hosts just about 8 months after the first disease signs. Up to now, no conclusive risk factors were determined. According to the evidences we’ve collected and the high increase of incidence last year, it might be caused by an infectious agent. CDC and other worldwide agencies are investigating whether some new virus, bacteria or parasite is responsible for this disease.” Researchers sought to establish bacterial or fungal colonies in dish culture, yet they were unsuccessful. As a result, they performed 16S rRNA to explore the possibility of a bacterium chronic infection, although no distinct bacterial genetic material was found in any patient, if when compared to healthy negative control. Afterwards, they suspected that an unknown new virus could be the outbreak source, so they decided to use a nanopore sequencing technology on cancer cells total DNA, looking for any unknown virus. However, nothing was found yet. Several months went by and scientists in the lab tested many hypotheses, although they could not identify the transmission route of this nasty malady. Some issues went through their minds. “How could a cancer spread from one person to another contaminating about 47,5 percent of the human population? It’s got to be viral, there is no other reasonable explanation”, they said to themselves. “Two years since zero patient and more than 17% of global population have deceased. According to CDC estimates, the situation is critic.” ... continue.
