Why the flu turns deadly for older adults, and how scientists found the cause

Scientists have discovered why older people are more likely to suffer severely from the flu, and can now use their findings to address this risk. In a new study, which is published in PNAS, experts discovered that older people produce a glycosylated protein called apoplipoprotein D (ApoD), which is involved…

Salmon’s secret superfood is smaller than a grain of salt
