Scientists announced Thursday that they have cracked the genetic code of all known species of the common cold virus, a major step forward in the effort to develop a cureâ??and perhaps even a vaccineâ??or the common cold.
The findings, published this week in the journal Science, highlighted why researchers have found it so difficult to build effective drugs to combat the virus, which sickens millions each year and sends thousands of children with asthma to the hospital.
