New insights into how influenza evades human immunity
Some viruses can only infect people once—measles for example. But other viruses, notably influenza, are capable of infecting repeatedly. Scientists have long puzzled over how the flu virus evades human immunity. Recent work in eLife clarifies exactly how the virus … Continue reading

Nitrogen-fixing bacteria talk to soybean roots via tiny RNAs, suggesting new avenue to improve yields
In order for soybean plants to get their necessary dose of nitrogen, they partner with bacteria called rhizobia, which can convert atmospheric nitrogen into organic forms the plant can use. But scientists don’t have the full picture of what facilitates … Continue reading
