A new study, conducted by the researchers from Arizona State University, USA, finds that traveling by plane is the fastest way for infectious diseases to spread. The spreading speed depends on such factors as place size and boarding method.
The researchers created a model simulating the spread of Ebola infection. The model can predict how many passengers would get an infection after using one of several different boarding methods. It also evaluates the influence of such factors as deplaning methods and plane size.
In their study, the researchers note: “Safer options include the two-section, random method, where the plane is divided into two lengthwise sections and passengers board randomly within those sections.”
Recently, a team of scientists from George Mason University have found that protein fragments in Komodo dragons’ blood have antimicrobial properties that help them resist toxic bacteria. Researchers figured out how these lizards became resistant to deadly infections in their mouths.
The scientist took blood from Komodo dragons and analysed it to find out whether they could trace of cationic antimicrobial peptides (CAMPs), the protein fragments that work as an essential part of our innate immune system.
The researchers hope that future studies of these peptides could lead to new antibiotic medications that can fight deadly superbugs. They wrote in their paper: “Future efforts will focus on determining whether peptides are constitutively produced or the result of pathogen detection, as well as whether this phenomenon is limited to Komodo dragons or if it occurs in other species, including humans.”
