System Disruption May Release Huge Amounts of Methane

April 18, 2014 7:00 am | by European Association of Geochemistry | News | Comments

Researchers have shown that humic substances act as fully regenerable electron acceptors which helps explain why large amount of methane are held in wetlands instead of being released to the atmosphere. However, there are worries that if this system is disrupted it may release large amounts of methane back into the atmosphere.

Specific Gene Controls Strawberry Sweetness

April 18, 2014 7:00 am | by The Conversation, Madeleine Martiniello | News | Comments

Two studies have found that the distinct flavor of strawberry has been linked to a specific gene, present in some varieties of the fruit– but not in others. The gene, FaFAD1, controls a key flavor volatile compound in strawberries called gamma-decalactone, which is described as fruity, sweet or peachy and contributes to fruit aroma.
