Genetically modified Bt cotton is the most widely planted cotton crop in India by acreage, and it is hugely controversial. Supporters long touted increased yields and reduced pesticides to justify its pickup. But that argument does not hold up under the first long-term study of Bt cotton impacts in India.

Monogamous Female Sea Turtles? Yes, Thanks to Sperm Storage

Findings provide insights into the relative numbers of males present in the breeding population, which are hard to get because males never come ashore.
