NewsResearchers show viral infections pose early heart risks
Myocarditis is often triggered by the body’s immune response to a viral infection, but a new study shows that the virus itself creates potentially dangerous conditions in the heart before inflammation sets in.

NewsMarine algae implants could boost crop yields
Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
