When humans are suffering from an infection, it is common to become fatigued and to want to sleep more than usual. Two studies on fruit flies published online ahead of print in the journal Sleep suggest that this instinct should be followed. The studies from researchers in the University of Pennsylvania show that sleep is important in increasing resistance to infection and promoting survival.

High-density lipoprotein (HDL), known colloquially as "good cholesterol", protects against dangerous deposits in the arteries. An important function of HDL is its anti-inflammatory properties. An international research team at the Institute of Innate Immunity at the University Hospital of Bonn and the LIMES Institute at the University of Bonn has identified a central switch by which HDL controls the inflammatory response. The results are presented in the current issue of "Nature Immunology".

A unique form of pink eye found in some songbird species has given researchers insight into how disease virulence – or severity of harm to the host – evolves in conjunction with a susceptible population’s density and/or disease resistance. These findings may help scientists understand and predict the impacts of highly contagious human diseases, like SARS or flu.
