New drug candidate found for hand, foot and mouth disease
(Duke University) Duke researchers have identified a potential drug candidate against enterovirus 71, a common cause of hand, foot and mouth disease in infants and young children. The compound of interest is a small molecule that binds to RNA, the virus's genetic material, and changes its 3-D shape in a way that stops the virus from multiplying without harming its human host. It's an antiviral strategy that could be used on other hard-to-treat diseases.

Cellular processes and social behaviors and... zombies?
(Arizona State University) The Zombie Apocalypse Medicine Meeting will happen online October 15-18, 2020. The meeting spans the sciences, the arts and the scary while bringing scientists, artists and journalists together with the general public. This year's meeting has been reanimated into a livestream broadcast on Channel Zed. Registrants will have access to programming on topics like how birth control, race relations, the pandemic, sex, literature and social media can all be thought of as zombification processes.

Nanoparticle SARS-CoV-2 model may speed drug discovery for COVID-19
(NIH/National Center for Advancing Translational Sciences (NCATS)) Scientists have developed a new tool that mimics how the virus that causes COVID-19 infects a cell, potentially speeding the search for treatments against the disease. The tool is a fluorescent nanoparticle probe that uses the spike protein on the virus surface to bind to cells and trigger the process that pulls the virus into cells. The probe could be used to rapidly gauge how drugs and compounds might block the virus from infecting cells.

Researchers find diminished response by 'killer' T cells in elderly COVID-19 patients
(American Society for Microbiology) Although people of any age can become infected with SARS-CoV-2, the virus that causes COVID-19, elderly patients face a higher risk of severity and death than younger patients. New research comparing the immune response among age groups, published this week in mBio, an open-access journal of the American Society for Microbiology, may help explain why. Older patients with the disease have lower frequencies of the immune cells needed to expel the virus from the body, the researchers found.

Long-term COVID-19 containment will be shaped by strength, duration of immunity
(Princeton University) New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection, according to a study by Princeton researchers published in the journal Science Sept. 21.
