Quality vs. quantity: Why 'super-shedders' may not be the superspreaders of disease outbreaks

A host that sheds an abundance of parasites might seem like an obvious disease-spreading threat. But new research suggests that shedding large volumes of parasites does not dictate transmission efficiency—and "super-shedders" may not be the superspreaders of infectious disease outbreaks.

Sediments off Brazil's northeast coast reveal sudden changes in heat transport in the Atlantic

According to a new study led by researchers from Brazil and Germany, the main system that transports heat from one end of the Atlantic Ocean to the other may undergo sudden changes in intensity driven by climate change similar to what we are experiencing now, even when it is already weakened.

Stable RNA elements open new possibilities for mRNA therapeutics

A research team led by Director Kim V. Narry at the Center for RNA Research within the Institute for Basic Science (IBS) has discovered compact viral RNA elements that can make mRNA more stable and increase protein production. These elements could provide a simple way to develop longer-lasting and more efficient mRNA technologies for vaccines and other RNA-based therapeutics.
