Common cold stopped by experimental approach
Scientists think they have found a way to stop the common cold and closely related viruses which can cause paralysis.
Instead of trying to attack them directly, the researchers targeted an essential protein inside our cells which the viruses need to replicate. The approach gave "complete protection" in experiments on mice and human lung cells. However, the US-based researchers are not ready for trials in people.
Tackling the common cold has been a massive problem in medicine.
Most colds are caused by rhinoviruses, but there are around 160 different types and they mutate so easily they rapidly become resistant to drugs, or learn to hide from the immune system.
This has led to the idea of "host-directed therapy" - essentially making our bodies inhospitable for the cold viruses.
An individual virus does not have everything it needs to replicate. Instead, it is dependent on infecting another cell and stealing some of the parts inside.
It is why scientists still argue whether viruses are truly alive.
