The most comprehensive synthesis of climate change impacts on the global availability of nutrients to date finds that, over the next 30 years, climate change and higher CO2 could significantly reduce the availability of critical nutrients, representing another challenge to global development and the fight to end undernutrition.

Waterhemp and Palmer amaranth, two aggressive weeds that threaten the food supply in North America, are increasingly hard to kill with commercially available herbicides. A novel approach known as genetic control could one day reduce the need for these chemicals. Now, scientists are one step closer.

Bee populations are declining, and neonicotinoid pesticides continue to be investigated -- and in some cases banned -- because of their suspected role as a contributing factor. However, limitations in sampling and analytical techniques have prevented a full understanding of the connection. Now, researchers describe a new approach to sample neonicotinoids and other pesticides in plants, which could explain how bees are exposed to the substances.

Recording the movements of people and animals has become easy because of small GPS devices and video cameras. However, the reasons for such movements remain difficult to infer. Scientists have developed a flexible artificial intelligence technology to understand the movement of animals, ranging from roundworms in petri dishes to penguins in the Antarctic Ocean. This method may make it easier to understand animal movements as well as their underlying brain activities.

CRISPR is thought of as 'molecular scissors' used to cut and edit DNA, but researchers are now looking far beyond these applications. In a new comprehensive review, they explore the current state of CRISPR in crops, and how scientists can enhance traditional breeding techniques in nontraditional ways to a growing population in the face of climate change, diseases, and pests.

A new study of cabbage crops in New York -- a state industry worth close to $60 million in 2017, according to the USDA -- reports for the first time that the effectiveness of releasing natural enemies to combat pests depends on the landscape surrounding the field.

Vector-borne diseases -- caused by parasites, viruses, and bacteria transmitted by insects and animals -- account for more than 17% of all infectious diseases on Earth. While many emerging infectious diseases (EIDs) are preventable through informed protective measures, the way that humans alter our landscape -- such as for farming and urban growth -- is making this task more difficult.
