High-speed genetic analysis looks deep inside primate immune system
(PhysOrg.com) -- Viruses such as HIV and influenza take safe harbor in cells, where they cannot be recognized directly by the immune system. The immune response relies on infected cells announcing the presence of the virus ...

Living longer -- variability in infection-fighting genes can be a boon for male survival
Females of mammals (including humans) tend to outlive males, a circumstance that is usually attributed to males´ more aggressive and hence energy-depleting behaviour, especially when they compete for females. This might ...

Diseases and sex: The cocktail maintaining immune gene variation
The great variation of a specific form of immune genes makes organ transplants so complicated. On the other hand, we need such a great variability in order to resist infectious diseases. This is why it also ...

Self or non-self: Social amoeba rely on genetic 'lock and key' to identify kin
The ability to identify self and non-self enables cells in more sophisticated animals to ward off invading infections, but it is critical to even simpler organisms such as the social amoebae Dictyostelium discoideum.

The importance of 'inner values': Female sparrows test the genetic make-up of their mates
How do females select partners? Darwin's initial idea that the fittest males would be the most desirable and would therefore be most likely to secure partners has represented a cornerstone of evolutionary theory since the ...

The spice of life: Variety is also good for hares
Since 1871, when Charles Darwin wrote The Descent of Man, it has been widely accepted that "Variability is the necessary basis for the action of selection." Variability is associated with the ability to adapt, which is clearly ...
