New system developed to deliver vaccines without refrigeration

Because they spoil without refrigeration, vaccines are notoriously difficult to transport to remote or dangerous places; as a result, millions of children around the world miss out on life-saving inoculations. However, scientists at the University of Bath have found a way to prevent warmed-up vaccines from degrading. By encasing protein molecules in a silica shell, the structure remains intact even …

Researchers develop 3D-printable material that mimics biological tissues

University of Colorado Denver researchers are the first to 3D print a complex, porous lattice structure using liquid crystal elastomers (LCEs), creating devices that can mimic cartilage and other biological tissues. Creating synthetic replacements which truly match the properties and behaviours of biological tissues hasn’t been easy. But University of Colorado Denver scientists, led by mechanical engineer professor Chris Yakacki, …

In development: Neutralizing antibodies and medicines that block viral replication

Researchers at the University of Toronto’s Donnelly Centre are working on two key projects in the battle against COVID-19: developing neutralizing antibodies to help boost patient immunity to the virus, and designing antiviral medicines that block viral replication. “With our two funded projects, we are working to develop molecules that can target the virus both inside human cells and on …
