Additives for vaccine storage to improve thermal stability of adenoviruses from hours to months

Francesco Stellacci, Paulo Henrique Jacob Silva, Valeria Cagno, Randy Patrick Carney

Up to 80% of the cost of vaccination programmes is due to the cold chain problem (that is, keeping vaccines cold). Inexpensive, biocompatible additives to slow down the degradation of virus particles would address the problem. Here we propose and character ...

Structure of viral membrane-penetrating machines by electron cryo-microscopy and tomography

Sergey Nazarov

My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...

Who will develop new antibacterial agents?

Stewart Cole

The golden age of antimicrobial drug development is a distant memory, and the likelihood of there being another seems slim. In part, this is because the pharmaceutical industry, which has now adopted an unsustainable business model, abandoned the anti-infe ...

Finding Trojan Message Vulnerabilities in Distributed Systems

Rachid Guerraoui, George Candea, Radu Banabic

Trojan messages are messages that seem correct to the receiver but cannot be generated by any correct sender. Such messages constitute major vulnerability points of a distributed system---they constitute ideal targets for a malicious actor and facilitate f ...
