Scientists in Hong Kong have reported the first confirmed case of reinfection with the coronavirus that causes Covid-19, reportedly backed up by genetic sequences of the two episodes of the 33-year-old man’s infections in March and in August 2020. Naturally, people are worried what this could mean for our chances of resolving the pandemic. Here’s why [...]
Could uncomfortable nasal swabs be swapped for a contactless two-second breathalyzer puff to check for Covid-19 infection? Prof. Hossam Haick thinks so. Haick, a professor of chemical engineering and nanotechnology at the Technion – Israel Institute of Technology, first came to our attention in 2011 for his invention of “NaNose,” which can sniff out [...]
The relationship between antibodies for the novel coronavirus (SARS-CoV-2) and immunity, vaccine efficacy, and spread of COVID-19 has received significant attention. Dr. Seheult is back to illustrate why T cells have received less attention than antibodies, but may be more important to long term immunity from COVID-19. Dr. Seheult also discusses how previous [...]
An upcoming NASA mission could find that there are more rogue planets – planets that float in space without orbiting a sun – than there are stars in the Milky Way, a new study theorizes. “This gives us a window into these worlds that we would otherwise not have,” said Samson Johnson, an astronomy [...]
Images Description Three individuals were admitted to the hospital (ages 46–56; to men and one woman) with a multiday history of symptoms associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and underwent contrast-enhanced thoracic CT due to worsening symptomatology. Three-dimensional (3D) digital models were created to visualise the extent of the disease [...]
Study of nose and throat reveals why people with COVID-19 may lose their sense of smell Researchers studying tissue removed from patients' noses during surgery believe they may have discovered the reason why so many people with COVID-19 lose their sense of smell, even when they have no other symptoms. In their experiments they [...]

Researchers around the world are racing to develop a vaccine against Covid-19, with more than 170 candidate vaccines now tracked by the World Health Organization (WHO). Vaccines normally require years of testing and additional time to produce at scale, but scientists are hoping to develop a coronavirus vaccine within 12 to 18 months. Vaccines mimic the [...]
Rising chorus of concern over Sputnik V vaccine stems from opaque development and lack of mass-testing. In 1977 Scott Halstead, a virologist at the University of Hawaii, was studying dengue fever when he noticed a now well-known but then unexpected feature of the disease. Animals that had already been exposed to one of the [...]
Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases for the last three decades and an expert on pandemics for the last four decades, has been optimistic on a vaccine arriving at the end of 2020 or in early 2021, but he has also cautioned the public on their expectations for [...]
