New research could help solve major challenge in the deployment of COVID-19 vaccines
New research by University of Texas at Dallas scientists could help solve a major challenge in the deployment of certain COVID-19 vaccines worldwide the need for the vaccines to be kept at below-freezing temperatures during transport and storage.
In a study published online April 13 in
Nature Communications, the researchers demonstrate a new, inexpensive technique that generates crystalline exoskeletons around delicate liposomes and other lipid nanoparticles and stabilizes them at room temperature for an extended period up to two months in their proof-of-concept experiments.
The Moderna and Pfizer/BioNTech COVID-19 vaccines use lipid nanoparticles basically spheres of fat molecules to protect and deliver the messenger RNA that generates a vaccine recipient s immune response to the SARS-CoV-2 virus.
This illustration depicts a proteoliposome a spherical bilayer of fat molecules (white and blue) stabilized in a structure called a zeolitic-imidazole framework composed of zinc acetate and methylimidazole. Inserted into the lipid bilayer which mimics a cell membrane are modeled structures of CopA proteins, with a section (in pink) that resides inside the lipid and sections above the lipid surface (brown) and slightly inside the liposome (also brown, but inside).

Two candidates are running for the Place 5 seat on the Round Rock City Council.
Tina Steiner, a longtime educator in the Round Rock school district, is running against Kristin Stevens, a pediatric speech-language pathologist. They are running to replace Writ Baese, who announced in January he would not be seeking reelection.
The winners of the May 1 election will serve a three-year term. Early voting begins April 19 and will run through April 27.
In the Place 1 race, Steiner, 58, who has worked in Round Rock schools for more than 20 years, said that if elected she will ensure the council remains transparent, fair and inclusive.
Just Kitchen, a provider of ghost kitchens in Taiwan, to start offering public shares in North America
0 55 5 minutes read Ghost kitchens have been a COVID-19 success story, and now one is set to go public, giving investors a chance to weigh in on the trend and its potential for future success. (Photo: Shutterstock)
On Thursday, Just Kitchen Holdings Corp. (TSXV: JK), an operator of ghost kitchens in Taiwan, will make its public debut on the TSX Venture Exchange in Canada. The company believes it is the first ghost kitchen operator to debut on a North American stock exchange, but it also provides a first glimpse into the faith the markets have on a concept that has exploded since the onset of the COVID pandemic.
