What is the key to a robust immunity against SARS-CoV-2? According to a study recently published in The New England Journal of Medicine, it could be a previous SARS infection—more specifically, the one that spread across 29 countries between 2002 and 2004—plus vaccination. 

A study in Science shed new light on the global epidemic obesity by evaluating nearly 650,000 exomes from the United Kingdom, United States and Mexico and identifying those with strong implications for body mass or obesity.

Regeneron Pharmaceuticals Inc. and AstraZeneca today announced that the companies entered into a collaboration to research, develop and commercialize small molecule compounds directed against the GPR75 target with the potential to treat obesity and related co-morbidities.

Since the 1800s, scientists have pushed governments to overhaul water supply systems for cleaner, safer water to stop the outbreak of waterborne pathogens. Now, researchers are calling for a similar “paradigm shift” in indoor ventilation systems to combat Covid-19 and other airborne pathogens.

A single dose of Pfizer’s coronavirus vaccine may not generate a sufficient immune response to protect against dominant new variants, except in people who have already been infected with Covid-19, according to a UK study published on April 30.

A new study report in Science suggests SARS-CoV-2 and its mutated new variants can evade immune responses via the selective deletion of small sections of the virus’s genetic sequence.

The data continues to come in on the various Covid-19 variants, and so far the news is pretty good, according to BioSpace.

Initially traced to about 100 cases of Covid-19 that spread across the United States, the number of infections linked to a Biogen corporate conference held in February 2020 at the Boston Marriott Long Wharf Hotel has grown exponentially and researchers estimate the total could be as many as 300,000.

In a Reuters roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for Covid-19, common cold antibodies yield clues to Covid-19 behavior.

The Nobel Prize in Chemistry was awarded to Emmanuelle Charpentier and Jennifer A. Doudna for their discovery and development of CRISPR gene editing.
