  • Infection with Sars-CoV-2 Renders a Robust Antibody Response for at least Three Months

    Infection with Sars-CoV-2 Renders a Robust Antibody Response for at least Three Months0

    Antibodies are one of the most valuable tools of the immune system to fight foreign invaders. As expected from work with other coronaviruses, several studies have confirmed that, following infection with Sars-CoV-2, the immune system counteracts by producing antibodies against the spike protein, a molecule that the virus uses to dock itself to our cells

    Covid-19 Candidate Vaccines Pass Safety and Efficacy Tests0

    Two candidate vaccines (ChAdOx1 and Ad-5-nCoV) for Covid-19 have been shown to be safe and efficacious in humans, according to two studies published this week in The Lancet journal. Both vaccines are based on adenovirus vectors, DNA viruses that act as vehicles to carry SARS-CoV-2 proteins to the body, therefore eliciting a response against an

  • The Molecules’ Marathon

    The Molecules’ Marathon0

    The benefits of exercise are not a surprise, and most of us have a fair sense of individual fitness. A recent article published in the Cell Journal1 went a step further and investigated what happens to the body at a molecular level after physical activity. Researchers at Stanford School of Medicine examined the molecular responses

    Nearly Every Recovered Covid-19 Patient Has Antibodies Against the Virus0

    Most of the patients who recover from Covid-19 have antibodies against SARS-CoV2, the coronavirus that causes the disease, shows a study published in the pre-print server medXriv (yet to be peer-reviewed). Researchers from the Mount Sinai School of Medicine recruited 1,343 patients who had tested positive or had symptoms for Covid-19 in New York City

    Are Viruses Alive?0

    Now that we are all tuned into virus talk, it may be a good idea to shed new light on an old debate. Arguments about whether viruses are alive have gone on for years. Expert opinion remains divided roughly a third each between yes, no and don’t know (surveys conducted by Vincent Racaniello on Virology

  • Study Reveals Geographic Differences in the SARS-CoV-2 Genomes

    Study Reveals Geographic Differences in the SARS-CoV-2 Genomes0

    Bioinformatic analysis of SARS-CoV-2 reveals several variations between the genomes of SARS-CoV-2 from Italy, India, Nepal and USA, and the SARS-CoV-2 originated from Wuhan. Researchers used a database of genomes, genes and proteins from SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic, and compared them with the SARS-CoV, the virus that originated an outbreak of
