May 21, 2021 — A novel defense mechanism for SARS-CoV-2 discovered Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients. |

October 12, 2020 — Age does not contribute to COVID-19 susceptibility Ryosuke Omori, Research Center for Zoonosis Control Scientists have estimated that the age of an individual does not indicate how likely they are to be infected by SARS-CoV-2. However, development of symptoms, progression of the disease, and mortality are age-dependent. |

|
September 8, 2020 – Cellular-level interactions that lead to the cytokine storm in COVID-19 Ryo Otsuka and Ken-ichiro Seino, Institute for Genetic Medicine Scientists review macrophage activation syndrome — a feature of the cytokine storm that kills patients with severe cases of COVID-19, as well as possible treatments. |
|
|
August 28, 2020 – Growth rate of the COVID-19 pandemic may be obscured due to changes in testing rates Ryosuke Omori, Research Center for Zoonosis Control Scientists have reviewed reported cases and testing data of COVID-19 and have determined that changes in the testing rate may be masking the true growth rate and extent of the pandemic. |

August 26, 2020 – SARS-CoV-2 RNA detected in untreated wastewater from Louisiana Masaaki Kitajima, Faculty of Engineering A group of scientists have detected genetic material from SARS-CoV-2 in untreated wastewater samples collected in April 2020 from two wastewater treatment plants in Louisiana, USA. |
|
|
August 12, 2020 – A quick, cost-effective method to track the spread of COVID-19 through untreated wastewater Masaaki Kitajima, Faculty of Engineering A group of researchers have demonstrated that, from seven methods commonly used to test for viruses in untreated wastewater, an adsorption-extraction technique can most efficiently detect SARS-CoV-2. This gives us another tool to detect the presence and spread of the COVID-19 pandemic. |

|
May 25, 2020 – Using wastewater to monitor COVID-19 Masaaki Kitajima, Faculty of Engineering Wastewater could be used as a surveillance tool to monitor the invasion, spread and eradication of COVID-19 in communities. |
|
|
May 22, 2020 – New technology can detect anti-virus antibody in 20 minutes Manabu Tokeshi, Faculty of Engineering Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19. |
