Increasing ventilation within aircraft cabins can reduce the spread of infectious diseases in-flight, suggests a review published in this week’s issue of The Lancet.
Mark Gendreau (Lahey Clinic Medical Centre, MA, USA) and colleagues reviewed data from studies looking at the transmission of diseases during commercial air travel. They found that while commercial airlines are a suitable environment for the spread of pathogens carried by passengers or crew, the environmental control systems used in commercial aircraft seem to restrict the spread of airborne pathogens. Proper ventilation within any confined space reduces the concentration of airborne organisms, with one air exchange removing 63% of airborne organisms suspended in that particular space. Computer models of data from an in-flight tuberculosis investigation reveal that doubling ventilation rate in the cabin reduced infection risk by half.
Investigations of in-flight transmission of tuberculosis suggest that the risk of disease transmission to other symptom-free passengers within the aircraft cabin is associated with sitting within two rows of a contagious passenger for a flight time of more than 8 h. This is believed to be relevant to other airborne infectious diseases. However, in one outbreak of SARS, passengers as far as seven rows away from the source passenger were affected.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
