Immune system sets 'tripwire' to protect against viruses

Scientists are opening new windows into understanding more about the constantly shifting evolutionary arms race between viruses and the hosts they seek to infect. Host organisms and pathogens are in a perennial chess match ...

Arabidopsis uses molecular decoy to trick pathogens

In the animal kingdom, predators use a full range of strategies, such as camouflage, speed and optical illusions, to catch their prey. Meanwhile, prey species resort to the same tactics to escape from their predators. Such ...

Administration developing penalties for cybertheft

Evidence of an unrelenting campaign of cyberstealing linked to the Chinese government is prompting the Obama administration to develop more aggressive responses to the theft of U.S. government data and corporate trade secrets.

Screening technique uncovers five new plant activator compounds

A new high-throughput screening technique developed by researchers at the RIKEN Plant Science Center (PSC) has been used to uncover five novel immune-priming compounds in Arabidopsis plants. Discovery of the compounds, which ...

Immunoproteasome crystal structure determined

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells ...
