Now scientists may have the key to warding off the sniffles. Reporting in the journal Cell last week, two separate research teams announced the discovery of a cell molecule to which rhinoviruses attach themselves. When the cold viruses bind to the molecule, known as the ICAM-1 receptor, they infect the cell.
The discovery means that synthetic copies of the molecule might one day be made into a...
