Monsanto is leading the fight to block a California ballot initiative that would require labeling of food with genetically modified ingredients.
Insect scientists say federal regulators need to take action against a growing pest problem in biotech corn.
They say corn rootworm has started to become resistant to Monsanto's Bt corn, which is genetically engineered to resist the damaging and costly pest.
The 22 scientists expressed their concerns in a letter sent to EPA earlier this week.
University of Illinois insect behaviorist Joseph Spencer was one of them.
Monsanto is entering a multi-year research collaboration with San Diego-based Sapphire Energy.
Sapphire specializes in genetically-engineering algae with the goal of producing drop-in replacements for fuels like gasoline, diesel and jet fuel.
The collaboration between Sapphire and Monsanto will focus on identifying genes that positively affect growth in algae and that might also increase agricultural crop yields.
