Flu virus mutates so quickly that one year’s vaccine won’t work on the next year’s common strains. But rational design – a new way to create vaccines – might pave the way for more lasting solutions.

Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants’ natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.
The only thing standing between invaders such as bacteria, viruses, parasites and fungi and our devastation is our immune system.

The immune system does such a good job most of the time that we only really think about it when things go wrong. But to provide such excellent protection, it must constantly learn.
The immune system protects us from the constant onslaught of viruses, bacteria and other types of pathogens we encounter throughout life. But it can sometimes misbehave.
